Abstract

An example of a surgical clip applier may include a housing with a passage defined therein, the passage having a longitudinal centerline; a plurality of clips held within the passage, each clip lying in a plane angled relative to the longitudinal centerline of the passage; a pusher slot defined in the housing; and a pusher slidable along the pusher slot, wherein distal motion of the pusher urges the distalmost clip in the passage out of the passage in a direction angled relative to the longitudinal centerline of the passage. Another example of a surgical clip applier may include a first jaw having a control slot defined therein; a second jaw having a control slot defined therein; and a control arm extending into the control slot of each jaw; wherein the control arm is movable along the control slots in a first direction to close the jaws and is movable along the control slots in a second direction to open the jaws.

Claims

1. A surgical clip applier, comprising:

a housing with a passage defined therein, said passage having a longitudinal centerline;

a plurality of clips held within said passage, each said clip lying in a plane angled relative to said longitudinal centerline of said passage;

a pusher slot defined in said housing; and

a pusher slidable along said pusher slot, wherein distal motion of said pusher urges the distalmost said clip in said passage out of said passage in a direction angled relative to the longitudinal centerline of said passage.

3. The surgical clip applier of claim 1, incorporating by reference all of the elements of that claim;

wherein each said clip is independent form and positioned adjacent to at least one other said clip.

4. The surgical clip applier of claim 1, incorporating by reference all of the elements of that claim;

further comprising a lower ramp located at the distal end of said passage;

wherein frictional force between said distalmost clip and said lower ramp holds said distalmost clip in place relative to said passage.

5. The surgical clip applier of claim 1, incorporating by reference all of the elements of that claim;

further comprising an upper ramp generally parallel to said lower ramp and spaced apart from said lower ramp by a distance slightly greater than the thickness of said clips.

6. The surgical clip applier of claim 1, incorporating by reference all of the elements of that claim;

wherein at least one said clip is generally U-shaped.

7. The surgical clip applier of claim 1, incorporating by reference all of the elements of that claim;

further comprising a clip pusher biased distally, wherein said clip pusher contacts the most-proximal clip in said passage, and wherein force in the distal direction applied by said clip pusher to said most-proximal clip is transmitted through said plurality of clips to said distalmost clip.

8. The surgical clip applier of claim 7, incorporating by reference all of the elements of that claim;

further comprising a spring connected to said clip pusher, wherein said spring biases said clip pusher distally.

9. The surgical clip applier of claim 8, incorporating by reference all of the elements of that claim;

wherein said pusher is movable into said passage as it urges the distalmost said clip in said passage out of said passage; and

wherein motion of said pusher back into said pusher slot allows said clips within said passage to advance distally within said passage.

10. The surgical clip applier of claim 1, incorporating by reference all of the elements of that claim;

wherein said pusher slot is underneath and generally parallel to said passage.

11. The surgical clip applier of claim 1, incorporating by reference all of the elements of that claim;

further comprising a handle coupled to said pusher, whereby actuation of said handle causes distal motion of said pusher.

12. The surgical clip applier of claim 11, incorporating by reference all of the elements of that claim;

wherein said handle includes a source of stored energy, whereby said stored energy is released to urge said pusher distally.

2. A surgical clip applier, comprising:

a first jaw having a control slot defined therein;

a second jaw having a control slot defined therein; and

a control arm extending into said control slot in each said jaw;

wherein said control arm is movable along said control slots in a first direction to close said jaws and is movable along said control slots in a second direction to open said jaws.

13. The surgical clip applier of claim 2, incorporating by reference all of the elements of that claim;

wherein at least one said clip is plastically deformable by said jaws.

14. The surgical clip applier of claim 2, incorporating by reference all of the elements of that claim;

wherein the distal end of each said jaw includes a finger angled relative to a remainder of said jaw.

15. The surgical clip applier of claim 14, incorporating by reference all of the elements of that claim;

further comprising at least one clip held at an angle relative to the longitudinal centerline of said control arm, and wherein each finger is angled substantially the same as said at least one clip.

16. The surgical clip applier of claim 2, incorporating by reference all of the elements of that claim;

further comprising at least one clip held at an angle relative to the longitudinal centerline of said control arm;

wherein each finger includes a trench defined therein on the inner surface thereof.

17. The surgical clip applier of claim 16, incorporating by reference all of the elements of that claim;

further comprising a pusher slidable to urge the distalmost said clip into position between said fingers along said trenches until said distalmost clip encounters the distal ends of said trenches.

18. The surgical clip applier of claim 2, incorporating by reference all of the elements of that claim;

wherein the distal end of each said control slot is located laterally outward from the proximal end of said control slot.

19. The surgical clip applier of claim 2, incorporating by reference all of the elements of that claim;

further comprising a handle coupled to said control arm, whereby actuation of said handle causes distal motion of said control arm and closure of said jaws.

20. The surgical clip applier of claim 19, incorporating by reference all of the elements of that claim;

wherein said handle includes a source of stored energy, whereby said stored energy is released to urge said control arm distally.
