Abstract

In order, in the case of a surgical ligature clip comprising two retaining arms, which are connected to one another in each case at one end by a deformable connection point and bendable in such a way towards one another that the arms move from an open position, in which they are spaced further apart from one another, into a closed position, in which the mutually opposing inner sides of the arms are brought permanently closer to one another, to improve the seat of the ligature clip on a hollow organ, it is proposed that it comprises an endless web member, which in the region of the two arms and the connection point forms two juxtaposed portions that merge one into the other at the free ends of the arms remote from the connection point.

Claims

1. Surgical ligature clip comprising two retaining arms, which are connected to one another in each case at one end by a deformable connection point and bendable in such a way towards one another that the arms move from an open position, in which they are spaced further apart from one another, into a closed position, in which the mutually opposing inner sides of the arms are brought permanently closer to one another, wherein it comprises an endless web member, which in the region of the two arms and the connection point forms two juxtaposed portions that merge into one other at the free ends of the arms remote from the connection point.

2. Ligature clip according to claim 1, wherein the web member has a constant width over its entire length.

3. Ligature clip according to claim 1, wherein the web member has a constant height over its entire length.

4. Ligature clip according to claim 1, wherein the web member has a constant cross section over its entire length.

5. Ligature clip according to claim 1, wherein the web member has a rectangular cross section over its entire length.

6. Ligature clip according to claim 1, wherein the juxtaposed portions are of a rectilinear form.

7. Ligature clip according to claim 6, wherein the juxtaposed portions extend parallel to one another.

8. Ligature clip according to claim 1, wherein the juxtaposed portions of an arm merge in an arcuate manner into one another in the region of the free end of the arm.

9. Ligature clip according to claim 8, wherein the juxtaposed portions of an arm merge in a circular-arcuate manner into one another in the region of the free end of the arm.

10. Ligature clip according to claim 1, wherein the juxtaposed portions at their end remote from the connection point open into transverse portions that project laterally in opposite directions.

11. Ligature clip according to claim 10, wherein the transverse portions at their outer ends remote from the juxtaposed portions merge into a clamping portion that extends at a spacing from the transverse portions at the side thereof remote from the juxtaposed portions.

12. Ligature clip according to claim 11, wherein the clamping portion extends substantially parallel to the transverse portions.

13. Ligature clip according to claim 11, wherein the transverse portions at the outer ends merge in an arcuate manner into the clamping portion.

14. Ligature clip according to claim 13, wherein the transverse portions at the outer ends merge in a circular-arcuate manner into the clamping portion.

15. Ligature clip according to claim 10, wherein the transverse portions and optionally the clamping portion lie in the same plane as the juxtaposed portions adjoining the transverse portions.

16. Ligature clip according to claim 11, wherein the clamping portion extends in an arcuate manner.

17. Ligature clip according to claim 16, wherein the clamping portion extends in a circular arcuate manner.

18. Ligature clip according to claim 16, wherein the clamping portion is bent in a direction away from the juxtaposed portions.

19. Ligature clip according to claim 11, wherein at least one clamping portion carries a projection that, when the clamping portions of the two arms lie adjacent to one another, engages into a recess of the other clamping portion.

20. Ligature clip according to claim 19, wherein the projection is a pin.

21. Ligature clip according to claim 19, wherein a plurality of projections are disposed on, and distributed over the longitudinal direction of, the clamping portion of one arm and corresponding recesses are disposed on the clamping portion of the other arm.

22. Ligature clip according to claim 1, wherein the juxtaposed portions extend in an arcuate manner.

23. Ligature clip according to claim 22, wherein the juxtaposed portions extend in a circular arcuate manner.

24. Ligature clip according to claim 23, wherein the juxtaposed portions in the region of the free end of the arms merge into one another with a constant radius of curvature.

25. Ligature clip according to claim 1, wherein the two juxtaposed portions of an arm at least over part of their length lie in one plane.

26. Ligature clip according to claim 25, wherein the two juxtaposed portions of an arm in each case at least over part of their length lie in different planes and that the two planes are inclined towards one another.

27. Ligature clip according to claim 1, wherein the web member is profiled on its side forming the inner side of the arms.

28. Ligature clip according to claim 27, wherein the profiling in the region of the free end of the arms is mouse-tooth profiling.

29. Ligature clip according to claim 1, wherein the arms on their free ends carry a detent device that, when the arms are brought closer to one another, leads to a detent connection of the arms in this region.

30. Ligature clip according to claim 29, wherein the detent device comprises at least one projection on one arm that in the closed state of the ligature clip engages behind a part of the other arm.

31. Ligature clip according to claim 30, wherein the projection has on its free end a widened portion or a bent portion.

32. Ligature clip according to claim 30, wherein the projection takes the form of a hook.

33. Ligature clip according to claim 1, wherein the web member is an integral component.

34. Ligature clip according to claim 1, wherein the two juxtaposed portions are connected to one another in the region of the connection point by means of a web.

35. Ligature clip according to claim 10, wherein the two juxtaposed portions are connected to one another in the region of the connection point by means of a web.

36. Set of a plurality of ligature clips, each of which comprises two retaining arms, which are connected to one another in each case at one end by a deformable connection point and bendable in such a way towards one another that the arms move from an open position, in which they are spaced further apart from one another, into a closed position, in which the mutually opposing inner sides of the arms are brought permanently closer to one another, each ligature clip comprising an endless web member that forms in the region of the two arms and the connection point two juxtaposed portions that merge one into the other at the free ends of the arms remote from the connection point, wherein all of the ligature clips are disposed on a common carrier that passes through the ligature clips, which are disposed parallel and in a row adjacent to one another, in the region of the space between the juxtaposed portions.

37. Set of a plurality of ligature clips according to claim 36, wherein the juxtaposed portions of the ligature clips lie at least in places closely adjacent to the carrier.
