Definitions
- a hemostat for clamping a severed blood vessel comprising a pair of pivotal handle members formed of the nonmetallic material and having web means for strengthening the handle member and having an offset nose portion to permit minimum lateral dimension of the hemostat in the area of the hemostat which will be adjacent the blood vessel to be clamped.
- Ligature means are provided on the hemostat for effecting a rapid tie and include disc means forming a one way knot in the ligature.
- This invention provides a surgical hemostat which has loaded thereon a length of ligature adapted to be used for ligating a severed blood vessel.
- the ligature is preloaded on the hemostat in a manner whereby the surgeon may quickly apply a noose-like portion of the ligature to the severed vessel and may contract the noose-like portion by pulling on the ligature at an area remote from the severed vessel.
- the instrument is extremely simple to operate and can ligate the severed ves sel in a fraction of the time required for manual tying. The particular location of the bleeder has little or no effect on the instrument. The instrument is completely safe and thereby avoids all of the hazards incident to the use of the electrocoagulation method.
- FIG. 1 is a front elevational view of the preferred embodiment of the present invention
- FIG. 2 is a side elevational view of the device shown in FIG. 1;
- FIG. 3 is a rear elevational view of the device of FIG. 1 shown in position to clamp a severed vessel;
- FIG. 4 is a view similar to FIG. 3 but showing the device after the ligature has been applied to the vessel;
- FIG. 5 is a fragmentary perspective view showing the completion of a ligating operation and cutoff method;
- FIG. 6 is a fragmentary perspective view showing the looping configuration of the ligature on the hemostat.
- FIG. 7 is a fragmentary perspective view showing further details of the device.
- the instrument comprises a pair of handle members 12 and 14 joined at an intermediate point by pivot means 16.
- the pivot means may be conveniently a metallic eyelet or may be a molded extension of one of the handle members.
- the handle members may be made of stainless steel as is conventional for surgical hemostats.
- the handles are made of a nonmetallic' material; for example a synthetic material such as nylon. polystyrene. etc.
- the handles are conveniently molded to lower the manufacturing costs of the instrument and thereby make it feasible to discard the instrument after a single use.
- Handle 14 has a nose portion 18 provided with a serrated edge 20 and a finger-receiving portion 22.
- Handle 12 has a nose portion 24 slightly larger than the nose portion 18, the portion 24 being provided with serrations 26 which cooperate with the serrations 20.
- a finger-receiving portion 28 is provided on handle member 12 and locking means 30 are provided on each of the handles 12 and 14 for maintaining the instrument in a closed position while also permitting openingof the instrument by disengaging the ratchet teeth of the locking means.
- Such locking means are conventional in prior art hemostats.
- Nose portion 24 is provided with an opening 32 therein, such opening being provided at the extreme tip of the nose portion.
- a metallic insert 34 is mounted within the opening 32 and has an edge 36 which constitutes a cutting surface. The insert 34 and opening 32 cooperate to form a passageway through which a ligature 38 extends.
- the covering may take various forms such as a length of tubing through which the ligature extends or the covering may merely consist ofa coating adhesively applied to the ligature.
- Securing means 42 comprises a series of ribs 44 through which the covering and ligature extend.
- the central rib is thermally deformed at 46 causing material from the central rib to flow into the channels between adjacent ribs to thereby entrap the covering and ligature.
- the handle members 12 and 14 are provided with longitudinally extending webs 48, which webs serve to add additional strength and rigidity to the handles. Offset sections 50 are provided in the handle members for bringing the nose portions 18 and 24 into longitudinal alignment.
- Retaining means 52 may comprise a pin-like member frictionally held within the pivot means or the retaining means may be combined as part of the pivot means and may be an integral part of one of the handle members.
- Retaining means 52 dle members as best seen in FIG. 2.
- One side of the retaining means is provided with a boss 54 (see FIG. 6) for receiving the ligature 38 as it exits from the covering 40.
- the ligature 38 passes around the boss 54 and then into the passageway formed by the opening 32 and the metallic insert 34. After passing through the opening 32 the ligature is formed into a noose 56, said noose being formed by the ligature being threaded through an apertured disc 58.
- the threading of the ligature through the disc provides essentially a one-way knot. that is the disc permits the noose 56 to be contracted rather easily while the disc also serves to prevent subsequent enlargement of the noose.
- the noose portion 56 is positioned around the handle members and is retained in position by the member 52. As is evident from FIG. 6 the noose 56 is placed outwardly on member 52 from the portion of ligature exiting from covering 40.
- the instrument In use the instrument will be in the condition shown in FIGS. land 2. A bleeder such as 60 which is to be ligated will be grasped by the nose portions 18 and 24 ofthe instrument as shown in FIG. 3 and the handle members will be closed into a locked position by engagement of a locking means 30. Sufficient force is developed in the nose portions of the instrument to perform temporary hemostasis of the vessel.
- the operator or surgeon will next grasp the covering 40 and will move the covering in a direction out of the paper and towards the reader. This movement of the covering and the ligature 38 therein will cause the ligature to be freed from the retaining means 52. This movement of the ligature off of boss 54 will also cause the noose 56 to be pulled off of the retaining member into a free position. The surgeon will then pull on the covering 40 until the covering and ligature are in the position shown in FIG. 4.
- the noose As the ligature is pulled towards the finger-receiving portion of the instrument the noose is constantly being contracted about the vessel 60. When the covering is in the position shown in FIG. 4 the noose will be in its fully contracted position about the vessel 60 and ligation of the vessel will be effected. The disc 58 will insure that the noose remains in its contracted or tightened position. As seen in FIG. the noose and disc are tightly secured about the vessel 60. The surgeon will then remove the excess portion of the ligature by grasping the ligature and applying pressure to the ligature in a direction towards the nose of the instrument, such pressure being effected conveniently by the surgeons thumb.
- the movement of the ligature towards the nose forces the ligature against the cutting edge 36 of the insert 34, thus severing the ligature closely adjacent the disc 58.
- the handle members With the tying thus effected the handle members will be moved to their open position and will be removed from the bleeder leaving only the small noose and disc around the bleeder. The noose and disc will remain on the bleeder and the wound or incision will then be closed.
- the material of which the ligature and disc are comprised will determine whether or not the ligature and disc are subsequently absorbed by the body. Both absorbable and nonabsorbable materials may be used safely and effectively for both the disc and ligature.
- the present invention has several distinct advantages over the ligating hemostat shown and described in the above-mentioned copending application Ser. No. 506,692.
- the present invention provides a more rapid ligation than is possible with the hemostat of the earlier filed application and also the present invention provides an instrument which remains unitary after a ligating function has been performed.
- the unwanted length of ligature was not secured to the hemostat at the end of a tying operation and therefore it was necessary that both the hemostat and the ligature be counted prior to closing of the wound to insure that no unwanted objects were left in the wound.
- With the present device only the instrument itself need be counted and this is a relatively easy task.
- a surgical instrument comprising first and second handle members, pivot means joining said members intermediate the ends thereof, each said handle member having a nose portion and a finger-receiving portion, one said nose portion being provided with an opening in its end, said opening being of sufficient size to permit the passage of a ligature therethrough, locking means provided adjacent said finger-receiving portions for maintaining said instrument in a closed position and for allowing said instrument to move to an open position.
- an offset section disposed in each said handle member between said nose portion and said pivot means, said offset section causing said nose portions to be in longitudinal alignment.
- securing means located on one said handle member adjacent the finger-receiving portion thereof.
