Abstract

A surgical clip may be configured to ligate tissue. The surgical clip may include first and second leg members. The first leg member may have a proximal portion, a distal portion, a convex first inner surface, and a convex first outer surface. The first leg member may also include an inner portion at least partially defining the first inner surface and an outer portion at least partially defining the first outer surface. The inner and outer portions may be joined at first and second portions of the first leg member and separated by a channel. The second leg member may include a proximal portion, a distal portion, a second inner surface, and a second outer surface. The first and second leg members may be movable relative to each other between open and closed configurations, and the first and second inner surfaces may be configured to ligate the tissue when in the closed configuration.

Claims (33)

1 . A surgical clip configured to ligate a tissue, the surgical clip comprising:

a first leg member including a first proximal end portion, a first distal end portion, a first inner portion, and a first outer portion, the first inner portion including a first inner surface, the first outer portion including a first outer surface, the first inner portion and the first outer portion being joined at a first portion and a second portion of the first leg member;

a second leg member including a second proximal end portion, a second distal end portion, and a second inner portion including a second inner surface;

wherein the first and second leg members are movable relative to each other between an open configuration and a closed configuration,

wherein the first inner surface and the second inner surface are configured to contact the tissue when the first and second leg members are in the closed configuration,

wherein the first inner surface of the first inner portion is convex and the second inner surface of the second inner portion is convex,

wherein the first and second inner surfaces are configured to pinch a proximal portion of the tissue as the first and second leg members are initially closed,

wherein the first outer portion is configured to elongate as the first and second leg members are moved to the closed configuration; and

wherein the first inner portion is configured to distribute pressure over a width of the tissue when the first and second leg members are in the closed configuration.

2 . The surgical clip according to claim 1 , wherein the first inner portion is configured to resiliently deflect toward the first outer portion when the first and second leg members are in the closed configuration.

3 . The surgical clip according to claim 2 , wherein the first inner portion further includes a first concave outer surface.

4 . The surgical clip according to claim 2 , wherein the first outer surface of the first outer portion is convex.

5 . The surgical clip according to claim 2 , wherein the first outer portion further includes a first concave inner surface.

6 . The surgical clip according to claim 1 , wherein the first inner portion has a width that is substantially equal to a width of the first outer portion.

7 . The surgical clip according to claim 1 , wherein the second leg member further includes a second outer portion, the second inner portion and the second outer portion being joined at a first portion and a second portion of the second leg member.

8 . The surgical clip according to claim 7 , wherein the second inner portion is configured to distribute pressure over the width of the tissue when the first and second leg members are in the closed configuration.

9 . The surgical clip according to claim 8 , wherein the second inner portion is configured to resiliently deflect toward the second outer portion when the first and second leg members are in the closed configuration.

10 . The surgical clip according to claim 7 , wherein the second outer portion further includes a second convex outer surface.

11 . The surgical clip according to claim 7 , wherein the second inner surface of the second inner portion is convex.

12 . The surgical clip according to claim 7 , wherein the second inner portion includes a second concave outer surface.

13 . The surgical clip according to claim 7 , wherein the second outer portion includes a second concave inner surface.

14 . The surgical clip according to claim 7 , wherein the second inner portion has a width that is greater than a width of the second outer portion.

15 . The surgical clip according to claim 1 , further comprising a first tooth on the first inner surface of the first inner portion, and a second tooth on the second inner surface of the second inner portion.

16 . The surgical clip according to claim 15 , wherein the first tooth is angled toward the first proximal end portion of the first leg member, and the second tooth is angled toward the second proximal end portion of the second leg member.

17 . The surgical clip according to claim 15 , wherein the first tooth extends along a width of the first inner portion, and the second tooth extends along a width of the second inner portion.

18 . The surgical clip according to claim 1 , further comprising a hinge portion integrally joining the proximal end portions of the first and second leg members, the hinge portion including a curved slot.

19 . A surgical clip configured to ligate a tissue, the surgical clip comprising:

a first leg member including a first proximal end portion, a first distal end portion, a first inner portion, and a first outer portion, the first inner portion including a first inner surface, the first outer portion including a first outer surface, the first inner portion and the first outer portion being joined at a first portion and a second portion of the first leg member; and

a second leg member including a second proximal end portion, a second distal end portion, a second inner portion including a second inner surface, and a second outer portion, the second inner portion and the second outer portion being joined at a first portion and a second portion of the second leg member;

wherein the second inner portion has a width that is greater than a width of the second outer portion,

wherein the first and second leg members are movable relative to each other between an open configuration and a closed configuration,

wherein the first inner surface and the second inner surface are configured to ligate the tissue when the first and second leg members are in the closed configuration, and

wherein the first inner portion is configured to distribute pressure over a width of the tissue when the first and second leg members are in the closed configuration.
