DEVICES FOR INVESTING WITHIN LIGAMENTS FOR RETRACTING AND REINFORCING THE
SAME
Abstract
A surgical instrument, guide, and method capable of being used for closure
of peritoneum fascia, occlusion of bleeding vessels such as inferior
epigastric, and for all uses related to accurately passing suture
material through a guide into tissue. A tip of a surgical instrument in a
standard suture-needle-driving position with a sharp tip that opens and
closes with the surgeon grasping suture material with the sharp tip is
provided. Insertion of the tip/suture through tissue until the tip is
seen through the peritoneum by direct vision begins the wound-closing
procedure. The suture is released by opening and withdrawing the tip from
the guide. The suture is recovered by using the guide to redirect the tip
and puncturing the tissue opposite the first point of insertion. The tip
grasps the suture and pulls the suture through the guide. The suture is
pulled outside the wound, providing for rapid closure of the surgical
incision. The guide is insertable within the wound to be closed and
guides the surgical instrument at a predetermined angle from the
longitudinal axis of the guide for optimum wound closure. The surgical
instrument and method may be used to advantageously shorten and
strengthen ligaments. For example, by gathering and reinforcing the round
ligament that supports a woman's uterus with suture materials, surgeons
can reposition and stabilize a retroverted uterus. Other devices may be
also used in connection with retracting and reinforcing connective
tissue. For example, rather than relying entirely on suture material to
hold connective tissue in a retracted state, a device having one or more
anchors may be inserted into connective tissue.

applications of which the present application is a divisional,
continuation, or a continuation-in-part, are incorporated herein by this
reference thereto.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to improvements in the procedure for
suturing tissue during endoscopic/laparoscopic surgery, and to a method
of suturing which utilizes a modified laparoscopic grasper and a guide.
More particularly, the improved method relates to suturing of ligaments
using a needle-point suture passer to retract and reinforce the
ligaments, applications including uterine suspension and positioning.
Devices suitable for insertion into ligaments or tendons for retracting
and reinforcing the same in accordance with the improved method are also
disclosed.
[0004] 2. Description of the Related Art
[0005] An endoscopic/laparoscopy procedure involves making small surgical
incisions in a patient's body for the insertion of trocar tubes thereby
creating access ports into the patient's body. Thereafter, various types
of endoscopic/laparoscopic instruments are passed through these access
ports and the appropriate surgical procedures are carried out.
[0006] After the surgical procedure is performed, the trocar tubes are
removed and the incisions sutured closed by using both a needle and
grasper for penetrating the tissue and handling the suture. This
procedure for closure is frequently a time-consuming procedure requiring
the identification of the fascia and closure of each fascial site with
suture from an external point.
[0007] The necessity for closing these port sites in laparoscopic surgery
is critical since suturing the incisions improperly can lead to bowel
herniation through the port sites as well as the possibility of omental
trapping if the fascial sites are not properly closed. Incisional hernias
have occurred in both laparoscopic-assisted vaginal hysterectomies and
laparoscopic cholecystectomies as well as other advanced laparoscopic
procedures.
[0008] Thus there is a need for an endoscopic/laparoscopic instrument and
method which will significantly reduce the operating time and is better
able to give the surgeon direct visualization of the fascial and
peritoneal closing. Additionally, there is a need for a surgical
instrument which allows the surgeon to control bleeding sites by rapidly
putting sutures around blood vessels of the abdominal wall.
[0009] Furthermore, there is a need to accurately and consistently guide
and orient an endoscopic/laparoscopic instrument into proper position to
accurately and easily provide for placement and retrieval of suture
materials within an open wound to be closed.
[0010] The subject invention herein solves all of these problems in a new
and unique manner which has not been part of the art previously. General
types of surgical forceps and laparoscopic graspers are known in the art,
and some related patents directed to surgical instruments or guides are
described below:

are eyelets or grooves or the like to guide the sutures as the knot is
being pushed. The purpose of the device is to advance the knot of a
suture through an endoscope portal or a cannula or the like.
U.S. Pat. No. 4,621,640 issued to J. S. Mulhollan on Nov. 11. 1986
[0021] This patent is directed to a mechanical needle carrier which can
grasp and carry a surgical needle through a cannula, position the needle,
and set a stitch at a remote location, then release the needle for
withdrawal from the cannula. The mechanical needle carrier is inserted
through the cannula, and a pivotal needle-carrying head is positioned by
adjusting knurled knobs SO as to position the needle as required. Once
the needle is set, it can be released and then retrieved by forceps or
the like. This mechanical needle carrier provides the structure for
suturing in a restricted field with the manipulation remote from the
location of the needle.
[0022] Intra-abdominal suturing is a time-consuming process for surgeons
in part because a lot of manipulation and "fiddling" is associated with
the needle attached to the suture material. For instance, the needle and
suture material must be aligned so they can pass through a trocar sleeve.
As curved needles will only fit through large trocar sleeves, larger
wounds must be made for the trocars in order to pass the curved needles
into the body cavity. Once inside the abdominal cavity, the needle has to
be grasped, regrasped, aligned, and realigned in the needle driver. After
each stitch, the needle has be to be grasped and realigned in the needle
driver.
[0023] With the present invention, the needle driver and the needle are
one and the same. Therefore, the disadvantages presented by having an
independent needle are avoided. Suturing can start immediately without
the frustration of continually realigning the needle when it is
regrasped. The surgeon simply passes the suture through the tissue then,
by either using the same instrument or a standard grasper, picks up the
suture for tying or passing through the tissue to create another stitch
for wound closure. The present invention allows introduction of suture
directly through tissue or through small trocar sites, as the diameter of
the shaft and its tip for the probe is generally much smaller than the
average trocar. Additionally, the technique for using the present
invention is easily learned; and the several embodiments set forth herein
generally reduce the time and frustration associated with intra-abdominal
suturing. These advantages are enhanced by use of the guide disclosed
herein.
[0024] Laparoscopic surgical procedures have been used in attempts to
correct misalignment of a woman's uterus. This misalignment is most often
seen as a retroverted, backward-bending uterus, but can also be an
anterior misalignment where the uterus is situated more toward the front
than is desired. Symptoms reported as a result include chronic pelvic
pain, pain on intercourse, debilitating pain during menstrual cycles,
urinary problems, bowel problems, infertility and back pain.
[0025] It has been found that repositioning the uterus to a more midline
position in the pelvis relieves symptoms in a great percentage of these
patients. To that end a number of surgical procedures have been attempted
to perform the correction.
[0026] The corrections revolve around surgeons' observations that
ligaments, or tough bands of tissue which normally function to hold the
uterus in a neutral position, are or have become stretched, thinned or
loosened from their attachment points. Procedures designed to shorten
and/or reattach these ineffective ligaments include the following:
Gilliams Procedure
[0027] The Gilliams procedure was designed to remove a section of the
ligament and suture the ends back together. The resulting shortened
ligaments provide more tension to hold the uterus in a neutral position.
Among the drawbacks to Gilliams procedure is that it does nothing to
improve the strength of thinned ligaments and they may again stretch so
that the correction would be short-lived. Additionally, Gilliams
procedure can change the geometry of the lower pelvis when ligaments are
reattached to the anterior abdominal wall, creating a pouch that may
entrap the bowel which is a serious complication.
Webster-Baldy Procedure
[0028] The Webster-Baldy procedure creates a new attachment point for one
ligament by passing it through another and suturing it to the wall of the
lower uterine corpus. This stretching of the ligament to a second
attachment point on the uterus creates more tension with which to hold
the uterus. This correction does not take advantage of the thickest part
of the ligament which is the part already attached to the uterus.
Changing the attachment point does nothing to improve the strength of
these thinned ligaments, and they may be prone to restretch.
Mann-Stenger Uterine Suspension, Candy's Modified Gilliam Uterine
Suspension, Pereyra Needle Uterine Suspension Doleris's Procedure
[0029] The above procedures rely on passing suture one or more times
around or through the ligament and then directly attaching the loose ends
of suture to the abdominal wall for the purpose of putting more tension
on the ligaments that support the uterus. The procedures do not reinforce
thinned ligaments which may stretch and loosen from the fixation. They
also create a cavity-like space in the anterior cul-de-sac where bowel
intussusception will be most likely to is occur. This may lead to a
slipping of a length of intestine into an adjacent portion, which may
produce an obstruction.
[0030] In contrast, the present invention uses a needle-point suture
passer to carry and withdraw suture longitudinally into the ligament from
a point at or near the ligament's original fixation point. Using this
method, the thinned part of the ligament is reinforced with permanent
suture, thus significantly reducing the risk of additional stretching. By
tunneling into the ligament from the area near the natural attachment
point, the natural geometry of the lower pelvis is preserved which
reduces the risk of complications.
[0031] In accordance with the improved method for retracting and/or
reinforcing ligaments to better support organs, there may be other ways
to accomplish the same rather than only routing suture in and out of the
ligament as described above. For example, it may be desirable to invest
specially configured devices into a ligament to accomplish the retracting
and/or reinforcing.
[0032] It has been known in the art to use splints or other devices to
repair lacerated or severed ligaments or tendons, or for use in place of
badly damaged connective tissues. The prior art devices may include
anchoring or securement structures for fixing the device in a ligament or
tendon, or for securing the device with sutures to the ligament or
tendon. Typically the devices are used to hold together opposing ends or
portions of connective tissue, while preparing for and waiting for the
healing process. Often the devices are made of materials which are at
least partially absorbed into the body over time, such that they need not
be removed once healing of the connective tissue has taken place. As
evident from the above. description, the prior art devices are not
suitable for use to retract and reinforce ligaments to better support
organs as envisioned by Applicant.
SUMMARY OF THE INVENTION
[0033] The present invention is directed to a suturing method using an
improved laparoscopic surgical instrument which permits a surgeon to pass
suture without trauma through tissue while retaining the function of
grasping the suture. The laparoscopic surgical instrument comprises a
modified laparoscopic grasper wherein forceps jaws at the tip are
manipulated by means of
handles extending from a tubular housing with an
enclosed reciprocating actuating rod connected with the
handles. As
contemplated in the present invention, scissor-type or syringe-type
handles may be used. In an alternative embodiment, a cannula may be used.
[0034] The laparoscopic surgical instrument of the present invention has
the tip of the forceps jaws modified to have either a knife-, chisel-, or
cone-shaped tip when the jaws are in the closed position. These tips are
configured such that they are needle sharp which is critical in reducing
trauma and accompanying bleeding and further decreases tissue damage
during the suturing procedure. Other tip configurations include curved
and bent tips, which allow greater facility under certain conditions.
Additionally, a suture probe guide delivering guided access to
appropriate tissue layers for suturing is provided.
[0035] The method of the present invention to shorten and strengthen a
ligament includes entering the person's body with a surgical tool having
a sharp tip and bearing suture material, and inserting the tool into the
ligament and pushing the suture material along the axial length of the
ligament. Then the method includes pulling the suture from outside the
ligament causing the ligament to retract along its length, and
incorporating the suture material such that the ligament is retracted and
reinforced. The resulting ligament is shorter, thicker and stronger, and
better able to support internal organs such as a woman's uterus.
[0036] Rather than using only suture materials to shorten and strengthen
connective tissue such as ligaments, tendons, etc., devices for
investment into connective tissues are also contemplated. The devices of
the present invention for such uses as insertion into the round ligament
to better support a woman's uterus, include an elongate body having one
or more spaced-apart anchors adapted to be fixed to the connective tissue
in a retracted condition, to hold the connective tissue in the retracted
condition. The elongate body of the device may include a deployable
anchor at the first end inserted into the ligament, and the opposing end
of the device may be attached to a nearby fixed structure of the human
body. Alternatively, both ends of the device may include one or more
opposing anchors or scales adapted to firmly hold the ligament in the
retracted condition.
[0037] Other alternate embodiments are contemplated, including a device
having an elongate substantially rigid body adapted to be screwed into
place inside the ligament in a retracted condition. Or the device may
include an elongate body extendable to a substantially straight
configuration inside the ligament, and retractable to a substantially
coiled configuration to hold the ligament in a retracted condition. A
device in combination with suture or glue could also be used to hold the
ligament in the retracted state.
OBJECTS OF THE INVENTION
[0038] It is an object of the invention is to provide a surgical method
for the closure of a surgical incision under direct camera laparoscopic
vision of the surgeon, and the closure that is accomplished is a mass
closure which allows for closure of peritoneal surfaces as well.
[0039] A further object of the invention is to provide a laparoscopic
instrument that allows for the rapid control of bleeding from inferior
epigastric lacerations or other lacerations of vessels in the outer (or
abdominal) wall that may occur with placement of the laparoscopy trocars.
[0040] Another object of the invention is to provide a laparoscopic
instrument that easily disassembles at the handle and at the interface
between the tube member and handle for providing easy access to all the
instrument components for cleaning and sterilization prior to surgery.
[0041] Still another object of the invention is to provide a laparoscopic
instrument having a pair of independently operated actuatable means such
that a single instrument can simultaneously perform both the functions of
a needle and grasper during laparoscopic surgery.
[0042] Yet another object of the present invention is to provide a
surgical instrument that works in a manner similar to a needle driver
without the requirement for the needle itself in passing suture easily
through the fascial and peritoneal surfaces and for retrieving the suture
for completing the suture procedure in a rapid, safe, and visualized
manner.
[0043] It is another object of the invention to provide a guide to
accurately and consistently restrain the position and angle of insertion
of a laparoscopic instrument to provide for proper placement and
retrieval of suture material at a predetermined location within the body.
[0044] Accordingly, it is an objective of the present invention to provide
a method associated with an improved surgical instrument of the standard
laparoscopic-type grasper that better suits the needs of a surgeon when
suturing closed a surgical incision. In addition, it is the objective of
the present invention to allow the passage of suture through tissue in
order to suture or ligate vessels, approximate tissues, and perform all
suturing that would require a separate needle driver in laparoscopic
surgery.
[0045] Another object of the invention is to provide a method of
laparoscopically inserting a suture within a ligament in a person's body,
causing the ligament to retract along its length and reinforcing the
ligament.
[0046] Still another object of the invention is to provide a method of
laparoscopically suturing the round ligament that supports a woman's
uterus to shorten and strengthen the ligament to reposition and stabilize
a misaligned uterus.
[0047] Finally, still another object of the invention is to provide a
method of laparoscopically suturing the round ligament that supports the
woman's uterus and anchoring the same to a bone, to reposition the
uterus.
[0048] Another object of the present invention is to provide a device for
investment into connective tissue of the human body to firmly hold the
connective tissue in a retracted condition.
[0049] Another object is to provide such a device adapted to facilitate
insertion into connective tissue and adapted to firmly hold the
connective tissue once retracted.
[0050] Another object is to provide such a device which automatically
deploys once inside connective tissue.
[0051] Another object is to provide such a device that need not be sutured
into place inside the connective tissue.
[0052] The improvements afforded by this instrument, and the methods and
devices of the present invention are set forth throughout the following
description, claims, and accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
[0118] Referring now to the drawings wherein like reference numerals refer
to like and corresponding parts throughout, the laparoscopic instrument
is generally indicated by numeral 20. Referring now to FIGS. 1a and 1b,
forceps jaws 24 and 26 are pivoted back and forth in double-action
movement about an axis defined by pivot pin 28 when actuating rod 36 is
reciprocated by a surgeon manipulating the scissor
handles 22 and 23
providing a driving means 25 for driving forceps jaws 24 and 26 in a
closed position through a patient's skin. Detachable means 27 comprise an
elongated tube 30 concentrically sharing an axis with the actuating rod
36 having forceps jaws 24 and 26 engaged at a distal end.
[0119] As shown in FIG. 1b, the laparoscopic instrument 20 may be easily
disassembled for sterilization prior to surgery by separating driving
means 25 from detachable means 27 by loosening the knurled screw 34 on
fixed handle housing 22, rotating the elongated tube 30 and forceps jaws
24 and 26 slightly, and unlatching hook 31 from pin 37 which thereby
frees actuating rod 36 and tube 30 from handle housing 22. By loosening
thumb screw 35, movable handle or lever means 23 can be disassembled from
fixed handle housing 22 that allows for cleaning of the inside of the
handle-housing area. When disassembled, the parts may be flushed, washed,
and dried according to hospital procedures for stainless steel surgical
instruments. A cleaning port 32 may be provided for ease in flushing the
disassembled fixed handle housing 22.
[0120] With the above-described arrangement, it will be seen that the
surgeon is able to selectively operate the scissor handles 22 and 23 to
independently open and close the movable forceps jaw 24 in relationship
to fixed forceps jaw 26 for grasping, carrying, or releasing suture
during a laparoscopic operation. To open forceps jaw 24, the surgeon
moves movable handle or lever means 23 forward toward the distal end of
tube 30. As shown in FIGS. 2 and 3, the forceps jaws 24 and 26 have a
chisel shape 38 and 40 which, when closed, form a chisel-shape tip 42.
This chisel-shape tip 42 operates as a sharp needle point that
simultaneously grips and passes the suture through soft tissue. Referring
to FIG. 4, chisel-shaped jaw 38 pivots open and closed about pivot pin 28
and chisel-shaped jaw 40 which is fixed and non-pivotable.
[0121] Although the forceps jaws are shown as chisel shaped in FIGS. 2 and
3, they may alternatively have a cone shape 44 and 46, forming a
cone-shaped tip 48 as shown in FIGS. 5 and 6. Referring to FIG. 7,
cone-shaped jaw 44 also pivots open and closed about pivot pin 28 and
cone-shaped jaw 46 which is fixed and non-pivotable. Alternatively, the
aforementioned forceps jaws may have individual knife-shaped tips 50 and
52 forming a knife-shaped tip 54 as shown in FIGS. 8 and 9. Likewise, as
shown in FIG. 10, the knife-shaped jaw 50 pivots open and closed about
pivot pin 28 and knife-shaped jaw 52 which is fixed and non-pivotable. In
all the above views, the tips are required to be sharp which is critical
in reducing trauma and accompanying bleeding and in decreasing tissue
damage during the suturing procedure.
[0122] Common to the variously shaped jaw embodiments is a generally
partial crosshatched interior jaw surface 58 embedded in jaw body 56, as
shown in FIG. 11, which facilitates in grasping more securely the suture
material 66 during insertion into tissue. In order to maintain the
sharpness of the tip, a partial nonhatched area 60 is provided at the
forward end of jaw body 56.
[0123] FIGS. 12 and 13 show another embodiment of a means to retain the
sharpness of the tip at the end of jaw body 56 when the forceps jaws are
closed. In FIG. 12 it is seen that lower forceps jaw body 26 is inclined
by a small angle, indicated at 74, toward pivot-pin hole 62. With this
arrangement the small angle 74 accounts for the thickness of the suture
such that, when the jaws are closed, a sharp tip is still defined with
the suture grasped resulting from the clearance provided by small angle
74. Additionally, a spring 64 is provided which has one end affixed into
jaw body 26 at a point near pivot-pin hole 62. The spring 64 assists in
more firmly grasping the suture material by adding a compression force
resulting in a more positive grip when the jaws 24 and 26 are closed as
shown in FIGS. 13 and 13a. The spring 64 is especially useful in handling
suture material that is large in diameter, therefore allowing for a wider
range of suture sizes that can be used during surgery.
[0124] These features and their advantages in use will be more
particularly appreciated when reviewing the following method of the
present invention used to pass suture through soft tissues during
endoscopic/laparoscopic surgery for which the instrument 20 of this
invention is provided. In application the surgical instrument 20 is to be
grasped by a skilled laparoscopic surgeon and placed for closure of
punctured vessels in the muscular surface or for closure of the fascia
and peritoneum.
[0125] FIGS. 14a through 14e are diagrammatic representations of one
example of using the method and laparoscopic instrument 20 with the
knife-shaped tip 54 of the present invention grasping and passing suture
through soft tissue for closure of an incision 72. In FIG. 14a the
surgeon grasps the suture material 66 with tip 54 and inserts instrument
20 carrying suture material 66 through the muscle fascia 70 and
peritoneum 68 until the tip 54 is seen through the peritoneum by direct
camera vision. Subsequently, the surgeon releases the suture 66 by
opening jaw 50 and withdrawing the instrument 20 out of incision 72 as
shown in FIG. 14b. In FIG. 14c the surgeon then takes instrument 20 and
inserts the tip 54 through the muscle fascia 70 and peritoneum 68
opposite the first point of insertion, grasping the suture 66 with jaws
50 and 52 and pulling the suture 66 carried and held by tip 54 outside
incision 72 as shown by FIG. 14d whereupon suture 66 is tied below the
skin to complete closure of incision 72 as shown by FIG. 14e.
[0126] It is to be pointed out that the knife-shaped tip 54 in the
above-described method may be replaced with either the chisel-shaped tip
42 or cone-shaped tip 48. Although not shown, it may be envisioned in the
above-described method that a second surgical instrument 20 may be
inserted through the muscle fascia 70 and peritoneum 68 opposite the
first point of insertion grasping the suture 66 with jaws 50 and 52 and
pulling the suture 66 held by tip 54 outside incision 72 by either an
assistant or the surgeon, resulting in a savings of time for completion
of the closure.
[0127] By way of example but not of limitation, it has been shown that, by
using the present invention during a laparoscopic-assisted vaginal
hysterectomy, the total time required for the closure of the two 12 mm
and one 10 mm trocar ports has been reduced from 15 minutes (as required
by prior surgical procedures) to 3 minutes.
[0128] As shown in FIGS. 15-25, additional alternative embodiments of the
present invention provide additional advantages for both specific and
general applications.
[0129] FIGS. 15 and 16 show a curved forceps tip 100. The curved forceps
tip 100 is curved in an S-shaped curve. The curved tip 100 has two jaws.
The lower and movable jaw 102 articulates downwardly from the upper and
fixed jaw 104. A pin 106 serves as a pivot point for the lower moving jaw
102.
[0130] Both the lower 102 and upper 104 jaws define lateral slots that
pass transversely across the inner faces of the jaws 102, 104. The slot
108 present in the lower jaw 102 is oppositely opposed the slot 110
present in the upper jaw. As shown in FIGS. 15 and 16, the slots 108, 110
are positioned toward the proximal end of the jaws 102, 104. As with the
small angle 74, as shown in FIG. 12, the slots 108, 110 accommodate
suture material 112 so that the two jaws 102, 104 may completely close
and provide the sharpest possible tip for tissue penetration. The
forwardmost end of the curved forceps tip 100 is exceedingly sharp so as
to provide easy and clean penetration of tissues.
[0131] The exterior surfaces of the lower and upper jaws 102, 104 are
smooth and round to quickly and easily push aside tissue penetrated by
the forwardmost end 114 of the tip 100.
[0132] The S-shape of the tip 100 provides the surgeon with a better means
by which to grasp suture, especially inside the body cavity. The angle
the curved tip 100 makes with respect to the probe's shaft 120 (FIG. 17)
allows the surgeon to more easily grasp suture that has positioned itself
alongside the curved tip 100. In contrast to a straight tip (such as that
shown in FIG. 18), the curved tip 100 allows the surgeon to rotate the
probe 122 in order to quickly grasp adjacently adjoining suture 112. If
the suture material is present immediately adjacent to the curved tip
100, a straight-edged tip would be ill-disposed to grasp material as the
surgeon would have to flex the probe within the surgical wound in order
to address the suture 112 with the tip. Additionally, the curved tip 100
allows the surgeon to grasp suture in tight confines having difficult
angles.
[0133] As shown in FIG. 17 as well as FIGS. 21, 22, and 25, the novel
handle structure 130 provides an alternative embodiment to that shown in
FIGS. 1a and 1b. As opposed to the scissors-type handle structure shown
in FIGS. 1a and 1b, the handle structure shown in FIG. 17 is of a syringe
type where a surgeon's first and second fingers may hold steady the
instrument as a whole with the thumb passing through a thumb loop to
control the articulation of the forceps tip.
[0134] As shown in FIG. 17, loops for the forefinger and second finger
132, 134 are oppositely opposed about a central stem 136 that provides a
solid foundation for the surgeon's hand. The shaft 120 of the probe 122
extends laterally from the central stem and terminates in the forceps
tip. Oppositely opposed the shaft 120 with respect to the central stem
136 is a rotatable thumb ring 138. The rotatable thumb ring 138 is freely
pivotable with respect to the central stem 136. The thumb ring 138 is
connected to a shaft 140 that communicates with the lower moving jaw 102.
By moving the thumb ring forward and backward, the lower moving jaw 102
is correspondingly closed and opened. Generally, as it is most
advantageous for the surgeon to firmly grasp the handle 130, the lower
moving jaw 102 will generally be closed when the thumb ring 138 is moved
forward and pressed toward the central stem 136 with its finger loops
132, 134.
[0135] A cleaning or flush port 146 is present toward the distal end of
the central stem 136. The cleaning port 146 has a cap 142 fitting over a
Luer-type fitting 144. In order to provide means by which the internal
structures of the probe 122 may be sterilized, the cleaning port may be
used to flush out the internal workings and surfaces of the probe 122. To
do so, the cap 142 is removed; and a hose having a compatible fitting is
attached to the cleaning port's Luer fitting 144. Cleaning or sterilizing
fluid may be then used to rinse the interior of the probe 122, flushing
out any particulate matter. This process is advantageously performed
before the probe 122 has been autoclaved. Chemical sterilization of the
probe 122 can also be performed through the port.
[0136] FIG. 18 shows a straight and conical forceps tip 150 having a fixed
upper 152 and moving lower 154 forceps jaws. Slots 156 and 158 are
disposed on the internal jaw faces toward the rear of the jaws 152, 154.
As previously described, these oppositely opposed slots provide
accommodation for suture material 160 so that the jaws may be completely
closed without gap between them for better penetration through tissue.
[0137] FIG. 19 shows the straight tip 150 in a closed position carrying
suture 160 between the jaws 152, 154 and the slots 156, 158. The lower
moving jaw 154 articulates about a pin 162.
[0138] FIG. 21 shows a straight forceps tip 150 carrying suture 160,
having the handle structure previously described in FIG. 17 and indicated
by reference number 130.
[0139] FIG. 20 shows a forceps tip much like that shown in FIG. 18 and 19
save that the shaft 170 immediately preceding the tip 172 has a bend 176
which disposes the tip 172 at an angle to the main portion of the shaft
174. The bend 176 serves to direct the tip 172 away from the major axis
of the main portion of the shaft 174. The tip 172 is then directed by the
bend 176 to travel along a minor axis defined by the tip 172 and portions
of the shaft 178 immediately behind the tip 172.
[0140] The tips angling off to one side of the probe shaft, such as those
shown in FIGS. 15, 16, and 20, allow the surgeon to tie suture knots more
easily and allow access to sites that would otherwise require
repositioning of the probe's insertion point and allow the surgeon to
avoid awkward hand positioning.
[0141] FIG. 22 shows a probe 180 similar to that shown in FIG. 21, the
shaft 182 of the probe 180 being relatively shorter than that shown in
FIG. 21.
[0142] FIGS. 23 and 24 show additional embodiments of forceps tips
contemplated for use in the present invention.
[0143] In FIG. 23, a transcutaneous grasper tip 190 is shown, having a
moving upper jaw 192 and a fixed lower jaw 104. As shown in FIG. 23,
serrations 196 are shown on the interior facial portions of the two jaws
192, 194. These serrations 196 are slightly offset to allow complete
closure of the transcutaneous grasper tip 190. When the tip 190 is
completely closed, the serrations of the lower jaw 194 are immediately
adjacent to the serrations 196 on the upper jaw.
[0144] When a probe 198, such as that shown in FIG. 25, has a
transcutaneous grasper tip 190, as shown in FIG. 23, tissues within the
body cavity are more easily grasped due to the increased friction arising
from the serrations 196. The probe 198 pierces the muscle fascia and the
peritoneum in order to enter the body cavity. Direct camera vision then
allows the surgeon to view the progress of the grasper tip 190 inside the
body cavity. When tissue of interest to the surgeon needs to be grasped
(for possible extraction or positioning), the grasper tip 190 is opened
and situated on either side of the tissue of interest. The grasper tip
190 is then closed by manipulation of the thumb ring 138. Once grasped by
the tip 190, the tissue is then moved into position according to the
surgeon's articulations of the probe 198.
[0145] The syringe-type handle design shown in FIG. 25 allows great
flexibility in positioning the instrument tip within the body cavity with
minimal hand movement required by the surgeon. This results in less
fatigue for the surgeon and allows the device to have much greater
utility. The flexibility of motion generally arises from the freely
rotatable thumb ring 138 and the handle 130. This allows the thumb
grasping the handle to move independently of the fingers. The handle 130
also allows the surgeon to rotate the instrument freely without releasing
his grip. This feature is not as greatly present in the scissors-type
handle shown in FIGS. 1a and 1b. Rotating the instrument while
maintaining instrument control is useful for general instrument
manipulation and special surgical maneuvers such as suture tying.
[0146] Materials used to construct the devices set forth herein include
surgical stainless steel and the like.
[0147] The present invention has been found to facilitate many
camera-viewed laparoscopic procedures. By varying the diameter, length
and curvature of the shaft, many procedures may be improved compared to
previously-existing methods. Laparoscopic port closure and the
identification and retraction of ureters during lymphadenectomy also
advantageously implement the present invention. The same is likewise true
for retraction of kidneys and other structures during laparoscopic
nephrectomy.
[0148] Intra-abdominal suturing, whether by closing of peritoneum or
intra-abdominal knot-tying, has benefited from use of the present
invention as has laparoscopic port closure (as for the urological uses
listed above). In general surgery, the present invention has been found
to be advantageously used with respect to laparoscopic port closures and
temporary and permanent fixations of hernia mesh. It is contemplated that
many other surgical procedures will advantageously use the present
inventive methods and instruments as described herein.
[0149] As shown in FIGS. 26-33, a specially adapted guide 220 can be used
in the suturing procedure discussed above, and its application is
demonstrated in FIGS. 31a-31c. The guide 220 provides the surgeon a
device and methodology for accurately and precisely positioning and
removing the suture material 66 in or from the patient's body where
desired.
[0150] The guide 220 has a longitudinal axis x shown in FIG. 26 and is
generally symmetrical about its x axis. Its proximal end 222 defines an
integrally-formed annulus 224 which serves as a gripping area for the
surgeon with a concave, radially disposed surface 226 which further
assists the surgeon in gripping and holding the guide 220. The concave
surface 226 may be smooth or knurled.
[0151] A top cylindrical recess 228 in the annulus 224 exposes two entry
holes 230 to generally linear passageways 232 through the guide 220. The
passageways 232 are appositely adjacent, and each forms a diverging angle
alpha of approximately 10.degree. with the longitudinal axis x but can
range over a number of angles less than 90.degree.. Optimally, the angle
is 9.6.degree. for an overall guide 220 length of 2.7 inches. The entry
holes 230 are located along a diameter line and are approximately 0.2
inches from center hole to center hole but may vary between 0.1 inches to
1 inch depending upon the desired angle x. The holes are sized to receive
the surgical instrument to be used.
[0152] In use, the annulus 226 stands proud of the wound but has an
undersurface or lip 234 which is adjacent the wound to be sutured. The
recess 228 provides access to the entry holes 230 and passageways 232 yet
prevents unwanted body fluids from obscuring the entry holes 230. The lip
234 prevents the guide 220 from sliding into the wound and, therefore,
should be sized to be of a greater diameter than that of the open wound
to be sutured.
[0153] A distal portion 240 of the guide 220 may be slightly tapered
although it may not be necessary. Tapering allows for greater ease of
insertion into the wound. The passageways 232 have exit holes 242 in the
distal portion 240 and may include a flaring 244 or tapering. The holes
230 and 242 to passageways 232 are sized to receive the surgical
tools to
be used and optimally may be less than one-quarter inch in diameter.
[0154] An extending finger 250 is adjacent the distal portion 240 and
primarily serves as an alignment or bearings indicator for the surgeon
viewing the procedure by camera. It is helpful to actually see the
relative positioning of the guide 220 by its extending finger 250 which
extends far enough down to where the viewing is taking place during the
operation. It is round on its distal end 252 for ease of insertion.
[0155] An index 254 may be located between the two entry holes 230 to
visually advise the surgeon to line up the index 254 with the cut of the
wound to ensure that suturing takes place at approximately 90.degree. to
the sliced walls of flesh.
[0156] The entire guide 220 can be integrally molded out of high-density
polyethylene or other comparable material which is durable and medically
inert or machined from stainless steel.
[0157] The distance L as shown in FIG. 27 between the undersurface 234 of
the annulus 224 and the exit holes 242 in the distal portion 240 is a
function of the patient's anatomy, in particular his or her body fat
composition. Ideally, the surgeon desires to reach a particular layer to
suture which may vary from patient to patient. Therefore, varying sized
guides 220 are anticipated with the length L being different and ranging
between 0.5 inches and 8 inches. Also, the overall length of the distal
portion 240 may vary depending upon the patient's anatomy, but an optimum
length ranges between 1.5 to 4 inches.
[0158] It is also possible to use the guide 220 of the present invention
with only one passageway 232; however, the surgeon would have to rotate
the guide 220 180.degree. to retrieve the suture material once the suture
material was deposited.
[0159] As can be seen in FIGS. 31a-31c, the guide greatly assists in the
procedure described above for FIGS. 14a-e. More particularly, the guide
220 is placed with the distal end 240 through the skin incision, muscle,
fascia, and peritoneum so that the finger distal tip 252 appears in the
view of the laparoscope. The guide 220 is oriented so that the holes 230
in the guide 220 are in the caudad-to-cephalad position.
[0160] The fascial closure instrument 20 (or 122) is inserted with suture
in its grasp through the cephalad hole in the guide 220 and observed to
exit through the peritoneum by laparoscopic view.
[0161] The suture is then released and the instrument 20 (or 122)
withdrawn from the guide 76. The instrument 20 is placed in the caudad
hole of the guide and watched by laparoscopic view to exit through the
peritoneum in the caudad position, therefore passing through fascia and
peritoneum on the caudad side of the incision. The guide 220 is then
withdrawn up on the shaft of the instrument 20, allowing the instrument
free mobility to grasp the suture that had been left with the first
passage.
[0162] The suture is withdrawn through the hole made by the instrument 20.
The guide 220 is then withdrawn from the suture completely. The suture is
then tied by standard techniques, thus encompassing the fascia and
peritoneum in a mass closure under the skin.
[0163] The guide 220 allows the suture instrument through fascia and
peritoneum and mass closure of all incisions greater than 5 mm and the
identification of the position of a trocar placement for use in occluding
a trocar site.
[0164] It also provides for placement in a trocar or other abdominal wall
site where a vessel, such as an inferior epigastric, has been lacerated
and allows passage of the instrument 20 for suturing of tissue around the
vessel to occlude the vessel and stop bleeding and for fascial closure of
any abdominal incision.
[0165] It provides for a method to obtain a measured amount of fascia and
peritoneum for laparoscopically controlled mass closure by varying the
length of the tool and the angle of the guide holes. By varying the tip
length and the length of the overall guide 220, visualizing the guide 220
itself, and placing the guide properly in incisions intra-abdominally,
closure of wounds in an individual of any weight is made possible.
[0166] By providing for the tip design, visualization of the guide 220
through the fascia and peritoneum is possible by laparoscopic
visualization, for repair of vascular damage to abdominal wall in any
area.
[0167] As can be seen by inspection of the Figures, particularly FIGS. 15,
20, and 27, some surgical instruments that do not maintain a straight or
linear configuration could not use the guide 220 with its long, straight
passages.
[0168] Alternative embodiments to the suture guide shown in FIGS. 26 et
seq. are shown in FIGS. 32-35.
[0169] A first alternative embodiment is shown in FIGS. 32 and 33 where
the suture guide 260 has a slot 262 allowing passage of the surgical
instrument through the guide and into the flesh to be sutured. The top
264 of the slot 262 provides the suture and surgical instrument with
access to the surgical wound while the side 266 of the slot 262 has the
adjacent flesh ready for suturing by the surgical instrument.
[0170] In most other aspects, the suture guide shown in FIG. 32 is similar
to that as shown in FIGS. 26 et seq., and like elements are labeled with
like reference numbers. Note should be taken that proximal end 222 is
bisected by slot 262 to form two wings 263, 265. The wings so formed
extend perpendicularly to the longitudinal axis x and can allow a surgeon
to more easily manipulate the suture guide 260.
[0171] The cross section view shown in FIG. 33 shows the central
supporting portion 268 which guides the suturing surgical instrument to
the adjacent flesh of the surgical wound. One advantage of the embodiment
shown in FIGS. 32 and 33 is that suturing surgical instruments having
bent tips or the like (such as those shown in FIGS. 15, 16, and 20) may
realize the advantages of using a suture guide that might otherwise be
prevented if the passage through which the suturing surgical instrument
had to pass could not accommodate the bent, or curved, tips.
[0172] Similarly, a second alternative embodiment of the suture guide
shown in FIGS. 26 et seq. is shown in FIGS. 34 and 35. Like elements are
labeled with like reference numbers; and like in the embodiments shown
FIGS. 32 and 33, a top slot 264 is present; however, the exit holes 242
are maintained. Guide barriers 270 are present in the alternative
embodiment shown in FIGS. 34 and 35. The suture guide 272 may still allow
suturing surgical instruments such as those in FIGS. 15, 16, and 20 to
use a suturing guide; however, the guide barriers 270 allow the surgeon
more guidance during the insertion process of the surgical instrument
into the suture guide 272.
[0173] Now referring to FIGS. 36-48, a method may be described for
suturing ligaments within a person's body using the laparoscopic, suture
passer instrument 20. In particular, the procedure described is for
retracting and reinforcing the ligament attached to a woman's uterus, to
reposition and stabilize the uterus to eliminate pain associated with its
misalignment. Patients with severe pelvic pain, pain with intercourse,
and severe painful menstruation may suffer from a backward-bending or a
retroverted uterus 302 (See FIGS. 36 and 46). If the uterus 302 can be
suspended and placed in its proper position, these pains may resolve.
Elevating the uterus 302 improves venous drainage and improves uterine
drainage at time of menstrual flow. Collision dyspareunia is avoided
since the cervix is pulled up out of the way.
[0174] Referring now to FIG. 37, first a small skin incision (not shown)
is made, overlying the area of the inguinal canal. Permanent suture
material 306 is then introduced using the needle-point suture passer 20
through the small skin incision, and passed through a first point 304 in
the muscle fascia 70, but not through the peritoneum, or broad ligament
68, in order to introduce the suture 66 within the preperitoneal space
overlying the round ligament 308. As shown in FIG. 38, the needle-point
suture passer 20 with the permanent suture 306 is passed through the
preperitoneal space and into the round ligament 308, preferably at its
thinnest section where it is attached to the peritoneum 68.
[0175] Referring to FIG. 39, approximately one to two centimeters from the
uterus 302 the needle-point suture passer 20 exits at a first point from
the round ligament 308 with the suture 306. The suture 306 is dropped,
and the needle-point suture passer 20 is withdrawn from the abdominal
cavity (see FIG. 40). The suture passer 20 (without suture) is
reintroduced through the same skin incision (not shown) at a second point
310 in the fascia 70 (see FIG. 41), so a fascial bridge 312 will be
created to fix the suspension (See FIG. 44).
[0176] FIG. 42 shows needle-point suture passer 20 being passed along the
round ligament 308 until a second point one to two centimeters from the
uterus 302 is reached. The needle-point suture passer 20 then grasps the
suture 306 and retrieves it within the round ligament 308 (FIG. 43).
Then, the needle-point suture passer 20 is used to pull the truncated and
thickened round ligament 308 within the peritoneum 68, providing the
preperitoneal 68 suspension of the uterus 302 (FIGS. 44 and 48). FIG.
47(A)-(E) shows a schematic view of the above-described procedure.
[0177] The round ligament 308 has now been thickened, shortened, and is
used in this manner to support the uterus 302 in a neutral position. The
opposite side was previously truncated and suspended with this technique,
the suture similarly applied externally under the skin and above the
fascial bridge 312 that was created. The final effect of the suspension
is shown in FIGS. 44 and 48, with the uterus 302 well placed in a neutral
or mildly anteverted position. In this manner, venostasis will not occur,
collision dyspareunia will not be experienced, and menstrual flow will be
easier. The preperitoneal uterine suspension using the needle-point
suture passer 20 is simple to perform, efficacious, and of great benefit
to patients.
[0178] Besides using the fascial bridge 312 to attach the suture material
306 to the peritoneum, other methods of fixing ligaments are also
contemplated. For example, ligaments reinforced with suture may be
attached to any anatomical anchoring point 314 such as a bone 316, or a
medical device 318 anchored to a bone 316. See FIG. 41A.
[0179] Although the above procedure for suturing ligaments describes
repositioning and stabilizing a woman's uterus, other applications are
contemplated. For example, the new methods may have application in
certain knee surgeries, and in breast-lift procedures.
[0180] Now referring to FIGS. 49-53, a number of devices for investment
into connective tissues such as ligaments may be described. These devices
once inserted into ligaments may serve to retain the ligaments in a
retracted condition, thereby better supporting organs in place, better
connecting particular extremities of bones, etc. The devices reduce the
amount of suturing and other manipulation required in and around
connective tissue to accomplish the retraction/reinforcement procedure
described above.
[0181] Referring first to FIG. 49, shown is a device 410 having an
elongate body 412 preferably fabricated of a braided cable. At one end of
the braided cable 412 is a deployable first anchor member 414, and at the
opposing end is a second anchor member 418. The deployable first anchor
member 414 preferably consists of a pair of folding anchors 415 pivotally
attached by a pin 416. The folding anchors 415 are able to pivot little
more than about 90.degree. or less from the axis of the length of braided
cable 412. In FIG. 49 the folding anchors 415 are shown partially
deployed. The second anchor member 418 preferably consists of a fascial
lock washer anchor, including a retaining washer 419 having a pair of
tabs 421. The tabs 421 of the retaining washer 419 are securable to the
braided cable 412, and upon installation the second anchor member 418
bears against the patient's fascia F.
[0182] Having described the structure of the device 410, it is now
possible to describe its use. The device 410 is inserted through the
fascia F into connective tissue CT, led by the deployable first anchor
member 414 and the braided cable 412. Upon the device 410 reaching an
appropriate location in the connective tissue CT, the folding anchors 415
are deployed and locked, and the braided cable 412 is pulled opposite the
direction of insertion. The folding anchors 415 become lodged in the
connective tissue CT and the pulling force causes the connective tissue
CT to gather and shorten. Then the retaining washer 419 is installed on
the braided cable 412, to bear against the fascia F. This maintains the
connective tissue CT in the retracted condition.
[0183] Next referring to FIG. 50, shown is a device 430 having an elongate
body 432 preferably fabricated of a polymer material. Included in both
the front and back sides of the elongate body 432 are two sets of
opposing, protruding scales 434 and 435. The device 430 also preferably
includes a protective covering or sheath 436 over all of the elongate
body 432.
[0184] In use, the device 430 including the sheath 436 is inserted into
connective tissue CT. A portion of the sheath 436 is removed, and the
exposed set of protruding scales 434 are embedded into the connective
tissue CT. The connective tissue CT is put in the retracted condition,
and the other set of protruding scales 435 are exposed and embedded into
nearby connective tissue CT. The device 430 maintains the connective
tissue CT in the retracted position without use of sutures.
[0185] Referring to FIG. 51, shown is a coil-like device 440. The device
may include a substantially rigid elongate body 442 which may be screwed
into place inside connective tissue CT. That is, the elongate body 442 is
rotated and advanced into the connective tissue CT, and the elongate body
442 is sized to engage the connective tissue CT as it advances therein.
The end result is shortening and strengthening of the connective tissue
CT by the presence of the device 440.
[0186] Alternatively, the device 440 may include an elongate body 446 set
to the coil shape shown. Then the elongate body 446 may be extended or
stretched or temporarily deformed into a substantially straight
configuration (not shown), and inserted into connective tissue CT. Next,
the elongate body 446 is released from the extended configuration and
reverts back to the set coil shape. In so doing, the connective tissue CT
is again similarly shortened and strengthened.
[0187] Moving along to FIG. 52, shown is a device 450 including a
deployable anchor 452 preferably fabricated of Teflon.RTM. covered with
felt, and a length of conventional suture 454. The device 450 is
preferably delivered inside connective tissue CT by a plunger P, and then
the device is released from the plunger P and the anchor 452 lodges
itself into the connective tissue CT. The opposing end of the suture 454
may be pulled opposite the direction of insertion causing the connective
tissue CT to gather and shorten. Then the suture 454 is tied off on the
patient's fascia F or other anchoring structure (not shown).
[0188] FIG. 53 shows a device 460 including a pad or pledget 462
preferably fabricated of felt-covered Teflon.RTM., and conventional
suture 464. The pledget 462 is preferably attached to the exterior of
connective tissue CT by the suture 464, which is routed in the connective
tissue CT, through the pledget 462, and out back through the connective
tissue CT. The suture 464 is pulled opposite the direction of insertion
and tied off on the patient's fascia F or other anchoring structure.
[0189] FIG. 54 shows use of a device 470 including an elongate body 472.
Conventional suture 474 at opposing ends of the elongate body 472 holds
the connective tissue CT in a retracted condition.
[0190] Finally, FIG. 55 shows a device 480 including an elongate body 482
preferably fabricated of an interwoven fabric material. The device 480
further includes deposits of a strong glue-like material such as fibrin
484, which is made from blood components. The device 480 may further
include a sheath 486 that initially covers all of the elongate body 482.
[0191] Once the device 480 is inserted and the connective tissue CT is
brought into the retracted condition, the sheath 486 is removed and
exposed fibrin 484 serves to adhere the elongate body 482 to the
connective tissue CT. Over time the connective tissue CT grows into the
interwoven fabric of the elongate body 482, and the connective tissue is
maintained in the retracted state even after the breakdown of the fibrin
484.
[0192] It is understood that the exemplary methods described herein and
shown in the drawings represent only presently preferred embodiments of
the invention. Indeed, various modifications and additions may be made to
such embodiments without departing from the spirit and scope of the
invention. These and other modifications and additions may be obvious to
those skilled in the art and may be implemented to adapt the present
invention for use in a variety of different applications.
