During a surgical procedure, one hundred or more blood vessels may be due to one in the body of the Patient cut ;; ground. Although a larger number of capillaries through the incision can also be separated, these will stop by themselves through the formation of a blood clot, to bleed. Those blood vessels, however, have a diameter is much larger than that of the Ki. do not close by themselves and their blood flow must therefore be artificially inhibited. The usual A method of stopping the flow of blood in a severed vessel is to close the blood vessel,

The ligature device, after it has been inserted into the hemostat, can easily be applied to the blood vessel by clamping the blood vessel between the jaws, removing the pin to release the loop, placing the pestle holding member along the blood vessel and removing the pin from pulled away from the hemostat to tighten the loop around the blood vessel.

According to another aspect of the invention, the surgical ligature device comprises a tube, with a surgical ligature extending through the tube, and having one end attached to a movable member while the other end of the ligature has a loop formed therein, and a pestle retaining member through which the Ligature is threaded, so that a movement of the movable member against

The ligature 50 has an enlarged, for example knotted free end 5 with a larger diameter than each of the openings 1 to J5 and it extends from the free end 5 from the underside (as shown in FIG. JA ) of the disk 52 out through the Opening J and down through opening 2 to form a loop 6 on the top (as shown in Figure JA) surface of disk 52. After the loop 4 has been formed, the ligature runs upwards (as shown in FIG.

During work, a blood vessel is drawn between the gripping surfaces 20 and 22 of the jaws, ie in 7 g. d shown clamped and the hemostat is bent to form a meat pyramid, according to F- g. 'shown. The peg 34 is then removed, as shown in FIG. 3, 3 to release the sling 4, v: whether the movement of the free end 51 of the ligature 50 against the peg 34 causes the loop to contract. The disc 52 is then pushed into the position in which it lies along the blood vessel shown in Figure 3. Lev pin J4 is pulled away from the hemostat in order to pull the loop 4 tightly around the blood vessel and to stop the flow of blood, as in FIG in Fig. 4. Since the prevention of the blood vessel from expanding under the blood pressure contained therein, there is a tendency to press the loop ο against that part of the ligature 50 extending between the loop β and the disk 52, whereby this part is pressed against the disk 52, the loop is automatically held in its fully tightened position around the blood vessel

The presence of the locking projections 2-3 and ^ O, however, offers the option of first stopping the blood flow of the blood vessel with the hemostat, * ¹ bringing the jaws 10 and 18 into engagement by means of the locking projections 28 and 30 and the setting process to be carried out at a later point in time, for example after the blood flow to other vessels has been stopped.

gature device is preferably used if the ligature is made of catgut or cotton, for example. If, however, the ligature is made of a material such as, for example, llylone, which has a particularly low coefficient of friction, the ligature device preferably has a large number of loops, which press against the disc for each ligature when the loop is s blood vessel is blocked. The ligature device shown in FIG. 7 comprises a disk 100, for example made of nylon or stainless steel, which has four bores 101 to 10 ^ 1 penetrating the disk. The ligature (J g as in F "shown.) Has an enlarged end 105, UEAs on the upper- side of the disc is 100, DSE ligature downwardly (as in I x - g shown. 3) extends through the bore 102 to form a first loop 106 and upward (as shown in Fig. 7) through bore 10J5, across the top (as shown in Fig. 7) surface of disc 100 to form a second loop 107, down (as shown in Fig. 7) through bore 104 to form a loop 108, the loop extending between the disc and loop 106, up (as shown in Fig.) through bore 101 and between the Loop 107 and the disk 100.

Figure 6 shows the sling 108 after it has been released by removing the removable pin (not shown) from the hollow pivot pin (not shown) with the disc 100 slid into position along the blood vessel. When the detachable peg is sucked away from the hemostat to pull the loop 108 around the blood vessel, the tendency of the blood vessel to expand under the prevailing blood pressure causes the loops 106 and 107 to form the parts of the ligature between these loops and 107 of the disc 100 firmly against the disc 100 to secure the loop 108 in its fully tightened position around the blood vessel. After the loop 108 has been secured as described above, the portion of the ligature adjacent the cutting edge 48 'is pressed against the cutting edge to cut the ligature and the loop 108 remains firmly attached to the blood vessel, as shown in FIG.
