Abstract

A surgical clip is provided for ligating or transecting tissue, such as vessels, other tubular ducts, and the like and a surgical clip applier device for delivering and applying the surgical clip to the tissue. The surgical clip can include a spine and opposed arms extending from the spine where the arms can define a clamping length. In a resting state, the clip can be biased to a closed position such that the ends of each opposed arm are disposed in proximity to each other. With such biasing, when applied to a tissue, such as with a surgical clip applier, the clip can exert a positive clamping pressure to the tissue along the clamping length to seal the tissue and limit passage of fluids, such as blood, from the tissue.

Claims (30)

1. A surgical clip, comprising:

a spine having a height defined by a top edge and a bottom edge and extending along a longitudinal axis of the clip from at least one of a first clip end and a second clip end;

opposed arms extending from the top and bottom edges of the spine, the arms having a substantially straight length extending transverse to the longitudinal axis, the arms biased to a closed position such that ends of each opposed arm are disposed in proximity to each other to define a tissue-clamping region having a clamping length defined by the arms;

a frangible portion at a location along a length of the clip such that the clamping length of the tissue-clamping region can be selectively controlled; and

an incising element integrally formed on the spine and extending between the top edge to the bottom edge and configured to incise tissue in a direction parallel with the longitudinal axis of the clip.

2. The surgical clip of claim 1 , further comprising a plurality of frangible portions along the length of the clip such that the clamping length of the tissue-clamping region can be selectively controlled.

3. The surgical clip of claim 1 , wherein the spine of the clip is bendable along the longitudinal axis such that the shape of the clip can be selectively altered.

4. The surgical clip of claim 1 , wherein each opposed arm includes one or more slots disposed along the length of the clip, each slot extending from the ends of each opposed arm towards the spine in a direction substantially transverse to the longitudinal axis of the clip.

5. The surgical clip of claim 4 , wherein each slot terminates at a location in proximity to the spine.

6. The surgical clip of claim 1 , wherein the ends of the opposed arms comprise tissue-grasping elements adapted to secure the clip to a tissue.

7. The surgical clip of claim 6 , wherein tissue grasping elements of a first arm are staggered relative to tissue grasping elements of an opposed second arm along the length.

8. The surgical clip of claim 1 , wherein the length of the tissue-clamping region is greater than the length of the spine.

9. The surgical clip of claim 1 , wherein each of the opposed arms is oriented at an acute angle with respect to the spine.

10. The surgical clip of claim 1 , wherein the clip is formed of a material having spring properties, selected from the group consisting of a metal, a metal alloy, and a polymer.

11. The surgical clip of claim 10 , wherein the material is selected from the group consisting of nitinol, stainless steel, and spring steel.

12. The surgical clip of claim 10 , wherein the clip is formed of a bioabsorbable polymer.

13. The surgical clip of claim 12 , wherein the bioabsorbable polymer is selected from the group consisting of polyglycolide, polydioxanone, and polylactide.

14. The surgical clip of claim 1 , wherein the ends of the opposed arms contact each other in the closed position.

15. The surgical clip of claim 1 , wherein the ends of the opposed arms are spaced apart from each other in the closed position.

16. A surgical clip, comprising:

a spine having a height defined by a top edge and a bottom edge and extending along a longitudinal axis of the clip between a first clip end and a second clip end;

a plurality of top arms extending from the top edge of the spine and a plurality of bottom arms extending from a bottom edge of the spine, the arms having a substantially straight length extending transverse to the longitudinal axis, the plurality of top and bottom arms being biased to a closed position defining a tissue-clamping region having a clamping length defined by the arms; and

an incising element integrally formed on the spine and extending between the top edge to the bottom edge and configured to incise tissue in a direction parallel with the longitudinal axis of the clip.

17. The surgical clip of claim 16 , further comprising a plurality of frangible portions formed along a length of the clip such that a clamping length of the clip can be selectively controlled.

18. The surgical clip of claim 16 , wherein the spine of the clip is bendable along the longitudinal axis such that the shape of the clip can be selectively altered.

19. The surgical clip of claim 16 , wherein each of the plurality of top and bottom arms includes one or more slots disposed therebetween along a length of the clip, each slot extending from the ends of each top and bottom arm towards the spine in a direction substantially transverse to the longitudinal axis of the clip.

20. The surgical clip of claim 19 , wherein each slot terminates at a location in proximity to the spine.

21. The surgical clip of claim 16 , wherein the ends of the plurality of top and bottom arms comprise tissue-grasping elements adapted to secure the clip to a tissue.

22. The surgical clip of claim 16 , wherein each of the plurality of top and bottom arms is oriented at an acute angle with respect to the spine.

23. The surgical clip of claim 16 , wherein the clip is formed of a material having spring properties, selected from the group consisting of a metal, a metal alloy, and a polymer.
