Claims priority, application Germany July 3, 1953 9 Claims. (Cl. 128-326) The present invention relates to a ligature carrier, and more particularly to a ligature carrier which carries a pre-looped ligature ready for transfer to a surgical instrument.

It is one object of the present inventionto provide a ligature carrier to which a pre-looped ligature is detachably attached, so that it can be immediately transferred to a suitable ligaturing instrument capable of tightening the pre-looped ligature into a double knot on a blood vessel. Another object of the present invention is a ligature carrier including a plate which may remain directly on the surgical instrument as a protection for the ligature during the tying operation.

Another object of the present invention is a readylooped ligature arrangement including a supporting plate and a ligature, which can be prepared in non-sterilized condition, and then sterilized in large numbers while the ligature remains on the supporting plate.

With these objects in view, the present invention mainly consists in a ligature carrier which comprises, in combination, support plate means for supporting a ligature to be tied into a knot and having at least one first boss portion surrounded by a first loop portion of a ligature, and at least one second boss portion surrounded by another loop portion of the ligature, the respective loopportions constituting the inner and outer loops of a ligature knot tied on a blood vessel so that when the ligature is transferred to a surgical instrument, a double knot is easily tied by the surgical instrument on the blood vessel.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

Figure 1 is a plan view illustrating a ligature carrier according to the present invention;

Figure 2 is a sectional view of the ligature carrier shown in Figure 1 taken on line 11-41;

Figure 3 is a bottom view of the ligature carrier shown in Figure 1;

Figure 4 is a fragmentary plan view of a part of the ligature carrier;

Figure 5 is a plan view of another part of the ligature carrier;

Figure 6 is an exploded side view showing the parts of Figures 4 and 5;

Figure 7 is a longitudinal section of a magazine for the ligature carriers;

Figure 11 is a longitudinal sectional view illustrating a modified magazine for ligature carriers including an ejector member;

Figure 12 is a cross sectional view taken on line XII XII of Figure 11;

Figure 13 is a plan view of a ligature carrier according to the modified embodiment of the present invention;

Figure 14 is a view partly in section on line XlV- XIV in Figure 13 and showing a surgical instrument for tying blood vessels;

Figure 15 is a plan view of the arrangement shown in Figure 14 with a part of the ligature carrier removed; and

Figure 16 is a side elevation showing the ligature carrier in the condition of Figure 15, and including the surgical instrument.

Referring now to the drawings, and more particularly to Figures 1 to 6, a ligature 1 consisting of catgut, for example, is attached in pre-looped condition to a supporting plate means and wound in two loops 2 and 3 so that a double knot is produced when the loops 2 and 3 are later on tightened by a surgical instrument. The crossing points 5 and 6 of the two loops are disposed above each other. The supporting plate means may consist of metal, or artificial transparent material, and has such a size and shape as to correspond to the shape of corresponding portions of a ligaturing instrument, as is, for example, described in the co-pending applications Serial No. 347,336, now abandoned and Serial No. 402,359.

Boss portions 7, 8 and 9 project above the surface of support plate 4 and are part of another plate 10. The center boss portion 7 has an opening passing therethrough and is consequently tubular, whereas the other boss portions 8 and 9 are short solid pins. Boss portions 7, 8 and 9 project through openings 7 8' and 9 in plate 4.

The ligature 1 is wound about the boss portions 7, 8 and 9 in front of plate 4. The ends 11 and 12 of the ligature are guided around the edge 13 of plate '4 and placed under the surface 14 of plate 10 so that they are attached to the ligature carrier 4, 10 by the clamping pressure between the plates 4 and 10. After a ligature has been wound on the ligature carrier as above described, it can be sterilized together with the carrier, and the supporting plate 10 and 7 can be discarded as waste after the ligature has been transferred to a surgical instrument.

Ready-looped ligature carriers are stored in a magazine of the type shown in Figures 7 to 12. The magazine has a base 15 with a tubular guide wall 16. A container 17 containing a stack of ligature carriers is inserted into the tubular guide wall 16 so that its open end is closed. Slots 18 and 19 are provided in the container 17 and in the guide wall 16 through which the ligature carrier plates can be removed by pincers, while successive ligature carriers move down to the base plate 15. A guide rib 2.0 is provided in container 17 for holding the carrier plates 4 in proper position, and engages a notch in the carrier plate 4. The free ends of the ligature are located on both sides of'the guide rib 20.

in the modified magazine shown in Figures 9 and 10, instead of the guide rib 20, a guide rod 21 is provided which passes through the center opening 7 and 7' of the ligature carriers. Theend of the guide rod 21 is spaced from the base plate to permit removal of ligature carriers through slots 18 and 19, which can be aligned by turning container 17 through out of the position shown in Figure 9 in which the magazine is closed. In the modified embodiment of Figure 11, the foremost carrier plate is ejected through slots 18 by operation of a pusher member 22 which is normally retracted by a spring 23.

Figures 13 to 16 show a modified embodiment of the ligature carrier. A flat carrier plate 24 has wound thereon a ligature which. forms two loops which are held in.

position by a cover plate 25. Aligned holes 26 are provided in the carrier plate24 and in the cover plate. 25, and

additional aligned holes 29 are provided in plates 24 and 25. Carrier plate 24 has a flap 31 provided with notches and tongues 32 into which the free ends of the ligature 1 are clamped, and which constitute securing means for holding the ligature. The cover plate is perforated along lines 33 and can be broken along these lines when force is applied to the two flaps 34 and 35 thereon. V

The ligature carrier shown in Figure 13 is placed on a surgical ljgaturing instrument 27 which includes a pair of pins 30, forceps 28 for clamping a blood vessel, and buttons 37 for tightening a ligature. The ligature carrier is placed on the instrument with the forceps 28 passing through holes 26, and the pins located in the holes 29, cover plate 25 facing the instrument, and plate 24 facing outward. The free ends 36 of the ligature 1 are connected withbuttons 37 which were previously ughened, and after loosening of buttons 37 the free ends 36 of the ligature are tightened in the direction of the arrows in Figure 16 whereby the prepared loops of the ligature are detached from the plates 24 and 25 and lie around the forceps 28 and pins 30. Carrier plate 24 can now be removed, while cover plate 25 is broken by bending the same with the aid of flaps 34 and 35. In this manner the carrier is discarded, while the pre-looped ligature is now transferred to the surgical instrument.

In the embodiment of Figures 1 to 6, the ligature is transferred to the surgical instrument by placing the forceps in the opening 7, whereupon three ejector members of the instrument are actuated to act on boss portions 7, 8 and 9 to push plate 10 with bosses 7, 8 and 9 out of plate 4 so that the ready-looped ligature is located on the instrument. In this embodiment the plate 4 remains temporarily on the applicance during the tying of the blood vessel, and may be retained by resilient means acting on the cutout portions a and b.

It will be understood that each of the elementsdescribed above, or two or more together, may also find a useful application in other types of ligature carriers differing from the types described above.

The invention is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
