Abstract
A laparoscopic surgical ligation, repair, and electrosurgical coagulation and cutting device (10) has a central passageway (16) with first (26) and second (40) parallel channels on opposite sides thereof. A suture (18) extends through the central channel passageway (16) and has a loop (20) with a slip knot (22) on the distal end and a pull (24) on the proximal end. By pulling on the pull (24) the loop (20) can be drawn tightly about a tissue (50) to be ligated. An electrosurgical wire (28), connected (36) to a power source, slidably received in the first channel (26), has an electrically insulated body (30) extending through the first channel (26) with an exposed wire hook (32) formed at the distal end thereof for grasping the tissue (50) to pull it through the suture loop (20). A ligation assist device, such as a hypodermic needle (44) for providing anesthesia to the tissue (50) to be ligated or an optical fiber (46) for carrying laser energy for fulgurating the ligated tissue (50) is slidably received in the second channel (40). In one form, a nesting tube (74) is provided in one channel (26) to receive a suture needle (72) attached to a loopless suture (18) to easily suture to a body cavity wall (75). In another form, a tapered handle (12) frictionally receives a suture needle (72) attached to a looped (20) and slip knotted (22) suture (18) to repair a tear or rupture in a body part (89) by suturing through one or more laparoscopies without tying ligature knots inside the body cavity. In a third form, a curved carrying device (92) in one channel (40) and a ligation assist device (76) in the other channel (26) permits ligation of large vessels (99) attached to a body part (110) by fibrous tissue (108).

Best ~ode ~or Carryinq Out The Inven~ion In accordance with this invention, a laparoscopic :: :
surgical ligation, repair, and ~lectrosurgical coagul~tion and cutting device 10 is provided. This device is designed primarily for female sterilization -~
in an out patient and~or office setting under local anesthesia. However, it can also be used for ligating blood vessels, for laparoscopic appendectomies or for any other ~issue ligation procedure. This device can ::.
be introduced through the abdomen to the operative . ~
site by means of a 3 mm or 5 mm trochar opening.
Viewing is done through an endoscope such as the ~electronic endoscope shown in my U.S. patent ~ appli~ation Serial No.~769,120, ~iled 30 September - 1991, entitled "Heat Sterilizable Elec~ronic Video Endoscope", which is introduced through a separate ~;~ trochar. Sin~e~this optical catheter is a micro ~ en~oscope, it can:also be introduced throuyh a 3 ~
: opening under local anesthesia. Thisl however, does : not preclude the;use of a much larger liaparoscope, : ~ ~ still utilizing local anesthesia.
Laparoscopic~device 10 comprises~an elon~ated ~;
25:: b:ody:or handle~12, ~hich may be extruded from a `~
: medically compatible plastic or other s~it:able :; :ma~erial. The~devioe can bei introduced through a : krochar of an endoscope, such as trochar:14, shown in Figure 3. A suitable device is shown in my U. S. ;~
Pat~nt No. 4,869,717, for "Gas Insu~flation Needle :~
With Instrument Port".
Handle 12 has a central passageway 16 through which a suture 18 extends. The distal end of suture 18 is formed with ~ loop 20 by means of a slip ~not ~;
WO93/21834 2 1 3 ~ 6 6 2 P~T/VS93/03857 22. The slip knot has a diameter larger than that of ~ :
passageway 16. The proximal end of suture 18 has a ~--pull in a form of a handle 24. ~.
A first channel 26 runs entirely along and intersects the surface o~ handle 12 to form a longitudinal groove which is generally parallel to passageway 16. This channel slidably receives an ~
electrosurgical wire 28 which is covered by electrical -~.
insulation 30 an~ terminates at the distal end in an ~:
exposed wire hook`32. A cutting blade 34 can be provided across the bight of the hook, as best ~een in `~
Figure 3. The proximal end of wire 28 is connected to an electrical connector 36 for attachment to a source of electrosurgical power (not shown). Wire 28 is longitudinally lidable and rotatabl~ within channel .~.
26 so that the tip of hook 32 can be used to grasp the ~
tissue to be ligate~ and~draw it through loop 20, as :-.";.
will be described more fully below. The cutting blade 34 can be used to cu~ he suture just beyond sl~p knot : 20 22 after t~e loop is drawn ~ig~t, as ~urther explained `~
below. ConYenien~ly, when not in use, wire 28 can be ~`~
drawn in the proxlmal direction so that the hook 32 and::~blade 34 are received in a recess 38 formed in the distal end of handle 12 as a transverse slot across 2S~ the convex end~of~handle 12 and intersecting th~ end : ~ : o~:channel 26, as best seen in Figures 3-7. `~
~ An option~l:seoond channel 40 can be pro~ided ...
: ~ ~ : which also runs:the entire length of hand~e 12, but ` `-spaced from channel 26, such as on the opposite side o~ passageway 16 ~om channel 26. This se~ond channel 40 in~ersects the surface of handle 12 to form a `.
longitudinal groove which is al~o generally parallel .~.
: ~ to passageway 16. Channel 40 can be used seleatively ~or receiYing o~her ligation devices. For ~xample, in : 35 Fi~ure 8, a hypodermic syringe 42 is shown with a long `' ;, ~
i`
..~,' ,^
WO93/218~ !2~1`.3 4 6 6 2 PCT/US93/03857 needle 44 attached thereto which extends through channel 40. It can be used initially to inject anesthesia to the tissue to be ligated, if this -procedure is deemed necessary. Usually, the :
anesthesia used t~ deaden the area of the abdomen where the trochars are inserted is suffic}ent and additional anes~hesia is not required.
Alternatively, channel 40 can be used to receive one or more optical fibers, such as optical fiber 46 Conveniently, the optical fiber can be connected to a suitable source 48 o~ laser light, as shown in Figure -~;
9, for providing laser light to the operative site to :
fulgurate the ligated tissue. ~:
The method of preforming a tubal ligation is diagrammatically illus~rated in Figures 10-17. In Figure 10, tissue to be liga~ed, such as fallopian tube 50 is shown~ The device 10 is positioned so that suture loop 20 is brought into proximity to a tubal section 52 of the tube 50 which is to be ligated. As 0 previously mentioned, this positioning is viewed through an endoscope inserted through a sep~rate tro~har. Once loop 20 is positioned, hook 32 is ~ ~ exte~ded to grasp the tubal section 52 and pull it : through suture loop 20 as shown in Figure 11. The : 25 physioian then pulls on handle 22 to place suture 18 under traction so:that loop 20 begins to pull tight around tubal section 52/ as shown~in Figure 12. Thu~
slip knot 22~ ~ngages the distal en~ of handle 12 and is held by ~lt as:the ~uture is drawn through knok 22 :`
to dr~w loop 20 tightly about tubal section 52. Hook ;-32 then i5 retracted, as shown in Figure 3, as the -~
final tightening of the slip knot is complet~d.
Once suture loop 20 has ~een pulled ti~ht, the ~;
hook 32 can be extended again so that blade 34 can be used to cut suture 18 just above sIip knot 22, as ".''',.':
: .
WO93/21834 `2 13 ~ 6 6 2 PCT/US93/03857 13 ~-~ .
shown in Figure 14. The completed ligation is shown :~
in Figure 15. `
For many physicians, this constitutes the end of . -.
the procedure. However, other physicians may choose .
to use the hook 32 as an electrosurgical device for cauterizing the ligated portion 52. This device may be used as either a mono-polar or a bi-polar unit. As illustrated in Figure 16, the wire hook is positioned ~:
adjacent ligated tissue 52 and electrosurgical current -~
is supplied to the hook to carry out the cauterizing procedure.
If desired, an additional or alternative ~- <
procedure may be undertaken wherein the laser f iber 46 ..
i5 used for photo coagulation of ligated section 52 or for photo ~aporization of the tissue, as illustrated : in Fiyure 17.
Other common surgical procedures are simplîf ied : by devices fur~her disclosed as modifications and enhancaments of the present invention. For example, ~ .
~: 2Q fixation sutures are used extensively in surgery to ~ .
hold an organ, temporarily, to a body cavity wall.
: ~ In~the abdominal cavity, fixation sutures are used to ~;~

Thi~ de~ice has an elonga~ed handle 12~ shown with a `.
; : : tapered dis~al end, having a cenkra. pa~sageway 16, as ~--il in the present invention, but only a single first .~channel ~6 is.utiliz d. A suture l8~extends through aid central passageway and has a suture needle 72 on the distal end thereof and a pull 24 on the proximal end thereo~. A nesting tu~e 74 is slida~ly received in the first ch~nnel 26 and has a distal opening to -;~

A second laparoscopic device provided with forceps 76 can be used to remove the suture needle from the nesting tube 74 and pass i' through the organ -77 to be fixed t;: the body cavity wall 75. When the needle 72 is replaced in the nesting tube 74, both ends of the su~ure 18 can be withdrawn into the device 70 and the dPViCe pulled out from the body cavity wall 75. Thereby the two su~ure 18 ends may be pas~ed through the body c~vity wall 75 and tied over a bolster 78. Thus, the applica~ion o~ a fixation suture is greatly simplified. The suture may be cut ~ ~

W093~21834 2 1 3 1 6 g 2 PCT/US93/03857 Frequently, organs in the abdominal, peritoneum or chest cavities are torn and require sewing of double, triple or more stitches. Doctors frequently have trouble learning and executing the tedious and :~
time consuming procedure of ligature knotting through .
a laparoscope. Therefore, in accordance with this ~ .
disclosure, a laparoscopic body part repair device 80 .
is provided to simplify the repair of structures inside a body cavity. This device, as shown in Figure .
24, also utilities a handle 12, central passageway 16, .
and a first channel 26. The handle 12 is shown as tapered on its distal end to provide an oblique ``~
surface to frictionally fit a nee~le 72 into first .~.
; channel ~6. It is understood that t~e distal end ~`
: 15 shape of handle 12 may be varied and still accomplish this~purpose. A suture 18 ex~ends through the central .`
passageway 16 and has a 1ODP 20 with a slip knot 22 on ~.
the~distal end thereof and a pull 24 on the proximal end thereof. A portion 82 of the suture 18 ext.ends :;
bey~nd the slip~knot 22 and has the suture needle 72 :~
a~tached thereto.~ The method of repairing structures in a body cavity is shown in Figures 24-27.
Originally, the needle 72 is frictionally nestsd in ~;
firs~ channel 26.:;~The defert is repaired ~y utilizing : 25~:~ a~:1aparoscopic~;~orceps device 76 introduced through a :;:

For the ligation of larger and medium sized blood vessels, cystic ducts, trachea and bronchi, clip appliers and staplers are not always reliable.
Therefore, ligating must he used to adequately close off the vessel. However, often the surgeon has to first free the vessel from a body part attached to it with fibrous tissue by blunt dissection with a dissecting instrument. Typically, this has to be done -~
to free a space for three ligatures. A device which ~:
can carry a ligature behind a vessel greatly simplifies this procedure. Therefore, in accordance -~
with this disclosure, a laparoscopic suture carrying de~ice so is provided t~ facilitate the ~igation of certain vessels with a high assurance of complete surgical closure. ~s~shown in Figuxes 28 and 29, ~his .-~
: ~ de~ice utilizes a handle 1~, shown with a tapered : distal~end, central pa~sageway 16, first channel ~6, and second channel 40. A suture 1~ extends through ; the central passageway 16 and has a loop ~0 with a slip; knot 22 on the~distal end thereof and a pull 24 on the proxima1~end~thereof. A por ion 82 of the suture 18 extends~beyond the slip knot 22 and has a Z5~ ab 96 a~tached there~o.~ A carrier device ~2 is ;51idably recei~ed~in the second channel 40. The aarrier device 92:has a generally U-shaped curve~ .
portion 93 at its dista1 end with a slit 94 along the inner surface thereof, as shown. As seen in Fig~res ~;~
.29 and 30, the suture end 82 with ~he tab 96 can be loaded in the carrier device 92 through the s1it 94O
The carri:er device 92 can be made of pr~-formed plastic, having a memory, such that the curvature 93 .
can be s~raightened when retracted into se ond channel ;~.:

device 76 is slidably received in the first channel 26.
The method of ligation for major vessels or ducts --~
is shown in Figures 31-35. The suture end 82 and tab .~
96 are brought behind the vessel 99 to a ligated by : :
tilting device 90 and then straightening it. This sufficiently pierces fibrous tissue 108 connecting ves~el 9~ to body part 110 to allow for the through placement of curved portion 93 of carrier device 92.
The laparo~copic forceps device 76 in first channel 26 ~ :
i~ used then to draw the tab 96 ~hrough the loop 20.
The device 90 can again be tilted to withdrawn carrier device 92 from ~ehind vessel 99 and swing it out of the way. Then the ligation 92 and suture 20 loops are closed by simultaneously pulling on the tab 96 with -~
the forceps 8~ and the pull 24 by hand. As shown in ~:
~ Figure 35, once the ligature is closed, the forceps ~:
;: ~ device 76 can be replaced with a laparoscopic scissors `~-~
: device ~6 to cut the excess suture beyond the knot 22.
: 20 : As seen in Fi~ures 36 and 37, the carrier device ~ ~, ~ . .
~92 may be replac d by a j-guide carrier 104 with a slotted tip 106 to releasably hold the suture tab 96.
The j-guide carri:er:104 may either be of pre-formed :`~
plastic or may be~hollow with a guide wire running 25~ through it such that the memory o~ the pl~stic forms h~: ~urvature when the guide wire is removed. ~-~

Best ~ode ~or Carryinq Out The Inven~ion In accordance with this invention, a laparoscopic :: :
surgical ligation, repair, and ~lectrosurgical coagul~tion and cutting device 10 is provided. This device is designed primarily for female sterilization -~
in an out patient and~or office setting under local anesthesia. However, it can also be used for ligating blood vessels, for laparoscopic appendectomies or for any other ~issue ligation procedure. This device can ::.
be introduced through the abdomen to the operative . ~
site by means of a 3 mm or 5 mm trochar opening.
Viewing is done through an endoscope such as the ~electronic endoscope shown in my U.S. patent ~ appli~ation Serial No.~769,120, ~iled 30 September - 1991, entitled "Heat Sterilizable Elec~ronic Video Endoscope", which is introduced through a separate ~;~ trochar. Sin~e~this optical catheter is a micro ~ en~oscope, it can:also be introduced throuyh a 3 ~
: opening under local anesthesia. Thisl however, does : not preclude the;use of a much larger liaparoscope, : ~ ~ still utilizing local anesthesia.
Laparoscopic~device 10 comprises~an elon~ated ~;
25:: b:ody:or handle~12, ~hich may be extruded from a `~
: medically compatible plastic or other s~it:able :; :ma~erial. The~devioe can bei introduced through a : krochar of an endoscope, such as trochar:14, shown in Figure 3. A suitable device is shown in my U. S. ;~
Pat~nt No. 4,869,717, for "Gas Insu~flation Needle :~
With Instrument Port".
Handle 12 has a central passageway 16 through which a suture 18 extends. The distal end of suture 18 is formed with ~ loop 20 by means of a slip ~not ~;
WO93/21834 2 1 3 ~ 6 6 2 P~T/VS93/03857 22. The slip knot has a diameter larger than that of ~ :
passageway 16. The proximal end of suture 18 has a ~--pull in a form of a handle 24. ~.
A first channel 26 runs entirely along and intersects the surface o~ handle 12 to form a longitudinal groove which is generally parallel to passageway 16. This channel slidably receives an ~
electrosurgical wire 28 which is covered by electrical -~.
insulation 30 an~ terminates at the distal end in an ~:
exposed wire hook`32. A cutting blade 34 can be provided across the bight of the hook, as best ~een in `~
Figure 3. The proximal end of wire 28 is connected to an electrical connector 36 for attachment to a source of electrosurgical power (not shown). Wire 28 is longitudinally lidable and rotatabl~ within channel .~.
26 so that the tip of hook 32 can be used to grasp the ~
tissue to be ligate~ and~draw it through loop 20, as :-.";.
will be described more fully below. The cutting blade 34 can be used to cu~ he suture just beyond sl~p knot : 20 22 after t~e loop is drawn ~ig~t, as ~urther explained `~
below. ConYenien~ly, when not in use, wire 28 can be ~`~
drawn in the proxlmal direction so that the hook 32 and::~blade 34 are received in a recess 38 formed in the distal end of handle 12 as a transverse slot across 2S~ the convex end~of~handle 12 and intersecting th~ end : ~ : o~:channel 26, as best seen in Figures 3-7. `~
~ An option~l:seoond channel 40 can be pro~ided ...
: ~ ~ : which also runs:the entire length of hand~e 12, but ` `-spaced from channel 26, such as on the opposite side o~ passageway 16 ~om channel 26. This se~ond channel 40 in~ersects the surface of handle 12 to form a `.
longitudinal groove which is al~o generally parallel .~.
: ~ to passageway 16. Channel 40 can be used seleatively ~or receiYing o~her ligation devices. For ~xample, in : 35 Fi~ure 8, a hypodermic syringe 42 is shown with a long `' ;, ~
i`
..~,' ,^
WO93/218~ !2~1`.3 4 6 6 2 PCT/US93/03857 needle 44 attached thereto which extends through channel 40. It can be used initially to inject anesthesia to the tissue to be ligated, if this -procedure is deemed necessary. Usually, the :
anesthesia used t~ deaden the area of the abdomen where the trochars are inserted is suffic}ent and additional anes~hesia is not required.
Alternatively, channel 40 can be used to receive one or more optical fibers, such as optical fiber 46 Conveniently, the optical fiber can be connected to a suitable source 48 o~ laser light, as shown in Figure -~;
9, for providing laser light to the operative site to :
fulgurate the ligated tissue. ~:
The method of preforming a tubal ligation is diagrammatically illus~rated in Figures 10-17. In Figure 10, tissue to be liga~ed, such as fallopian tube 50 is shown~ The device 10 is positioned so that suture loop 20 is brought into proximity to a tubal section 52 of the tube 50 which is to be ligated. As 0 previously mentioned, this positioning is viewed through an endoscope inserted through a sep~rate tro~har. Once loop 20 is positioned, hook 32 is ~ ~ exte~ded to grasp the tubal section 52 and pull it : through suture loop 20 as shown in Figure 11. The : 25 physioian then pulls on handle 22 to place suture 18 under traction so:that loop 20 begins to pull tight around tubal section 52/ as shown~in Figure 12. Thu~
slip knot 22~ ~ngages the distal en~ of handle 12 and is held by ~lt as:the ~uture is drawn through knok 22 :`
to dr~w loop 20 tightly about tubal section 52. Hook ;-32 then i5 retracted, as shown in Figure 3, as the -~
final tightening of the slip knot is complet~d.
Once suture loop 20 has ~een pulled ti~ht, the ~;
hook 32 can be extended again so that blade 34 can be used to cut suture 18 just above sIip knot 22, as ".''',.':
: .
WO93/21834 `2 13 ~ 6 6 2 PCT/US93/03857 13 ~-~ .
shown in Figure 14. The completed ligation is shown :~
in Figure 15. `
For many physicians, this constitutes the end of . -.
the procedure. However, other physicians may choose .
to use the hook 32 as an electrosurgical device for cauterizing the ligated portion 52. This device may be used as either a mono-polar or a bi-polar unit. As illustrated in Figure 16, the wire hook is positioned ~:
adjacent ligated tissue 52 and electrosurgical current -~
is supplied to the hook to carry out the cauterizing procedure.
If desired, an additional or alternative ~- <
procedure may be undertaken wherein the laser f iber 46 ..
i5 used for photo coagulation of ligated section 52 or for photo ~aporization of the tissue, as illustrated : in Fiyure 17.
Other common surgical procedures are simplîf ied : by devices fur~her disclosed as modifications and enhancaments of the present invention. For example, ~ .
~: 2Q fixation sutures are used extensively in surgery to ~ .
hold an organ, temporarily, to a body cavity wall.
: ~ In~the abdominal cavity, fixation sutures are used to ~;~
: temporarily hold organs such as the stomach, large bowel, small bowel and gall ~ladder to the abdominal ~wall. In accordance with this disclosure, a laparoscopic ~ixation suture device 70 is provided.
Thi~ de~ice has an elonga~ed handle 12~ shown with a `.
; : : tapered dis~al end, having a cenkra. pa~sageway 16, as ~--il in the present invention, but only a single first .~channel ~6 is.utiliz d. A suture l8~extends through aid central passageway and has a suture needle 72 on the distal end thereof and a pull 24 on the proximal end thereo~. A nesting tu~e 74 is slida~ly received in the first ch~nnel 26 and has a distal opening to -;~
frictionally receive the suture needle 72O The ~: ' W093/~l834 ; ~ 1 3 ~ ~ ~ 2 PCT/US93/03857 14 :
' nesting tube 74 may be made o~ medically compatible plastic, stainless steel, or other suitable material.
A second laparoscopic device provided with forceps 76 can be used to remove the suture needle from the nesting tube 74 and pass i' through the organ -77 to be fixed t;: the body cavity wall 75. When the needle 72 is replaced in the nesting tube 74, both ends of the su~ure 18 can be withdrawn into the device 70 and the dPViCe pulled out from the body cavity wall 75. Thereby the two su~ure 18 ends may be pas~ed through the body c~vity wall 75 and tied over a bolster 78. Thus, the applica~ion o~ a fixation suture is greatly simplified. The suture may be cut ~ ~
: at a later time, allowing the organ to return to its normal position. The procedure may be.viewed by an endoscope 7 9 .

:trochar and a:laparoscopic device provided:with 25 :~forceps 76 through a second troc~ar. As seen in Figures 20 and 21, the second laparoscopic device 7~
: is ~used to remo~Je~ ~he needle 72 and pass the suture 18 ::
thrc~u~h the organ 77. Figure 21 shows the procedure ~`
b~ing viewed through endoscope 79 inserted through a ; 30 .s~parate trochar. Figure 2~ shows the two ends of su~ure 18 being drawn ~hrough the body cavity wall 75 after needle 72 has bae~ replaced in nestinq tube 74. ~;

W093~21834 2 1 3 1 6 g 2 PCT/US93/03857 Frequently, organs in the abdominal, peritoneum or chest cavities are torn and require sewing of double, triple or more stitches. Doctors frequently have trouble learning and executing the tedious and :~
time consuming procedure of ligature knotting through .
a laparoscope. Therefore, in accordance with this ~ .
disclosure, a laparoscopic body part repair device 80 .
is provided to simplify the repair of structures inside a body cavity. This device, as shown in Figure .
24, also utilities a handle 12, central passageway 16, .
and a first channel 26. The handle 12 is shown as tapered on its distal end to provide an oblique ``~
surface to frictionally fit a nee~le 72 into first .~.
; channel ~6. It is understood that t~e distal end ~`
: 15 shape of handle 12 may be varied and still accomplish this~purpose. A suture 18 ex~ends through the central .`
passageway 16 and has a 1ODP 20 with a slip knot 22 on ~.
the~distal end thereof and a pull 24 on the proximal end thereof. A portion 82 of the suture 18 ext.ends :;
bey~nd the slip~knot 22 and has the suture needle 72 :~
a~tached thereto.~ The method of repairing structures in a body cavity is shown in Figures 24-27.
Originally, the needle 72 is frictionally nestsd in ~;
firs~ channel 26.:;~The defert is repaired ~y utilizing : 25~:~ a~:1aparoscopic~;~orceps device 76 introduced through a :;:

For the ligation of larger and medium sized blood vessels, cystic ducts, trachea and bronchi, clip appliers and staplers are not always reliable.
Therefore, ligating must he used to adequately close off the vessel. However, often the surgeon has to first free the vessel from a body part attached to it with fibrous tissue by blunt dissection with a dissecting instrument. Typically, this has to be done -~
to free a space for three ligatures. A device which ~:
can carry a ligature behind a vessel greatly simplifies this procedure. Therefore, in accordance -~
with this disclosure, a laparoscopic suture carrying de~ice so is provided t~ facilitate the ~igation of certain vessels with a high assurance of complete surgical closure. ~s~shown in Figuxes 28 and 29, ~his .-~
: ~ de~ice utilizes a handle 1~, shown with a tapered : distal~end, central pa~sageway 16, first channel ~6, and second channel 40. A suture 1~ extends through ; the central passageway 16 and has a loop ~0 with a slip; knot 22 on the~distal end thereof and a pull 24 on the proxima1~end~thereof. A por ion 82 of the suture 18 extends~beyond the slip knot 22 and has a Z5~ ab 96 a~tached there~o.~ A carrier device ~2 is ;51idably recei~ed~in the second channel 40. The aarrier device 92:has a generally U-shaped curve~ .
portion 93 at its dista1 end with a slit 94 along the inner surface thereof, as shown. As seen in Fig~res ~;~
.29 and 30, the suture end 82 with ~he tab 96 can be loaded in the carrier device 92 through the s1it 94O
The carri:er device 92 can be made of pr~-formed plastic, having a memory, such that the curvature 93 .
can be s~raightened when retracted into se ond channel ;~.:

The method of ligation for major vessels or ducts --~
is shown in Figures 31-35. The suture end 82 and tab .~
96 are brought behind the vessel 99 to a ligated by : :
tilting device 90 and then straightening it. This sufficiently pierces fibrous tissue 108 connecting ves~el 9~ to body part 110 to allow for the through placement of curved portion 93 of carrier device 92.
The laparo~copic forceps device 76 in first channel 26 ~ :
i~ used then to draw the tab 96 ~hrough the loop 20.
The device 90 can again be tilted to withdrawn carrier device 92 from ~ehind vessel 99 and swing it out of the way. Then the ligation 92 and suture 20 loops are closed by simultaneously pulling on the tab 96 with -~
the forceps 8~ and the pull 24 by hand. As shown in ~:
