Abstract

An elongated jaw assembly for pinching closed a medical clip in an elongated medical clip-applying device. The assembly has an elongated bifurcated set of jaw members on a set of jaw arms. The assembly has a first end and a second end with a curvilinear rail arranged on an edge of each of the arms. A movable cinch member is slidably disposed on the jaw assembly to effect both closure and spreading apart of said jaw members on a tissue pinching medical clip supported therebetween.

Claims

1. An elongated jaw assembly for pinching closed a clip, in an elongated clip-applying device, the assembly having a first end and a second end, comprising:

an elongated bifurcated set of jaw members on a set of jaw arms;

a curvilinear rail arranged on an edge of each of said arms; and

a movable cinch member slidably disposed on said jaw assembly to effect closure and spreading apart of said jaw members on a clip supported between said jaw members.

2. The jaw assembly as recited in claim 1, wherein said curvilinear rail is positioned on an upper surface of each of said arms.

3. The jaw assembly as recited in claim 2, wherein said curvilinear rail is formed into an elongated generally “

S”

shape on each of said arms.

4. The jaw assembly as recited in claim 1, wherein said cinch has a curved upper surface and a generally planar jaw-engaging lower surface.

5. The jaw assembly as recited in claim 4, wherein said planar jaw-engaging lower surface has a pair of rail-receiving tracks on an end thereof.

6. The jaw assembly as recited in claim 4, wherein said cinch member is arranged to slide on said rail-receiving tracks.

7. The jaw assembly as recited in claim 5, wherein each of said pair of rail-receiving tracks has an outer edge comprised of an outer cam surface.

8. The jaw assembly as recited in claim 5, wherein each of said pair of rail-receiving tracks has an inner edge comprised of a spreader block.

9. The jaw assembly as recited in claim 8, wherein said spreader block is of a generally circular configuration on said planar surface.

10. The jaw assembly as recited in claim 7, wherein said spreader block is disposed on said planar surface, between said outer cam surfaces.

11. The jaw assembly as recited in claim 1, wherein movement of said cinch member toward the first end effects pinching of the clip disposed between said jaws members.

12. The jaw assembly as recited in claim 11, wherein movement of said cinch member toward the second end effects unbiased spreading apart of said jaw members.

13. A method of pinching closed a clip in a substantially elongated clip-applying device, the device having a first end and a second end, the method comprising:

receiving the clip between a substantially elongated bifurcated set of jaw members on a set of jaw arms, each jaw member having a curvilinear rail positioned on each jaw arm;

advancing a cinch toward the first end to perform a squeezing movement of each of the curvilinear rails, and effect biasing of the jaw members such that the clip is pinched between the jaw members; and

advancing the cinch toward the second end to release the jaw members.

14. The method as recited in claim 13, further comprising receiving a second clip between the elongated bifurcated set of jaw members on the set of jaw arms.

15. The method recited in claim 13, wherein the cinch slides on rail-receiving tracks during advancement toward the first and second ends.

16. The method recited in claim 13, wherein the release of the jaw members opens the jaw members.

17. The method recited in claim 13, wherein the curvilinear rail is vertically disposed on each of the jaw arms.

18. The method recited in claim 13, wherein the curvilinear rail is a substantially elongated “

S”

shape on each of the arms.

19. An elongated jaw assembly in an elongated clip-applying device, said assembly having a first end and a second end, comprising:

a substantially elongated pair of jaw members on a set of jaw arms;

a curvilinear rail arranged on an edge of each of said arms; and

a movable cinch member slidably disposed on said jaw assembly to effect closure and opening of said jaw members.

20. The jaw assembly as recited in claim 19, wherein said curvilinear rail is vertically disposed on each of said arms.

21. The jaw assembly as recited in claim 19, wherein said curvilinear rail is a substantially elongated “

S”

shape on each of said arms.

22. The jaw assembly as recited in claim 19, wherein movement of said cinch member toward the first end effects pinching of a clip disposed between said jaws members.

23. The jaw assembly as recited in claim 19, wherein movement of said cinch member toward the second end effects a release of said jaw members.
