Abstract

Claims (30)

1. A clip applier configured to apply a surgical clip, the clip applier comprising:

first and second jaw members configured to engage the surgical clip;

an actuating member configured to pivot at least one of the first and second jaw members between an open configuration and a closed configuration;

a stabilizing member configured to engage the surgical clip, the stabilizing member being configured to move longitudinally with respect to the clip applier from a distal position at least partially between the first and second jaw members to a proximal position at least partially between the first and second jaw members; and

at least one pin connecting the stabilizing member to the first jaw member and/or the second jaw member,

wherein the at least one pin is configured to actuate movement of the stabilizing member between the distal position and the proximal position, such that movement of the stabilizing member is actuated by pivoting the at least one of the first and second jaw members between the open configuration and the closed configuration.

2. The clip applier of claim 1 , wherein the stabilizing member is configured to disengage the surgical clip when the stabilizing member is in the proximal position.

3. The clip applier of claim 1 , wherein the stabilizing member comprises at least one slot, the at least one pin is received in the at least one slot, and each pin of the at least one pin slides along a respective slot of the at least one slot to actuate the stabilizing member.

4. The clip applier of claim 3 , wherein the at least one slot is angled relative to a longitudinal axis of the clip applier.

5. The clip applier of claim 3 , wherein the at least one slot includes a first slot and a second slot, and the at least one pin includes a pin on each of the first and second jaw members.

6. The clip applier of claim 1 , wherein the stabilizing member is configured to stabilize a proximal portion of the surgical clip in a lateral direction.

7. The clip applier of claim 1 , wherein the stabilizing member includes first and second walls on a distal portion configured to receive a proximal portion of the surgical clip therebetween.

8. The clip applier of claim 1 , wherein the first jaw member comprises a first inner channel, the second jaw member comprises a second inner channel, and the stabilizing member is received in the first and second inner channels in the closed configuration.

9. The clip applier of claim 1 , further comprising a linkage connecting the actuating member and the first and second jaw member.

10. The clip applier of claim 1 , wherein the actuating member comprises an actuating rod.

11. The clip applier of claim 1 , wherein the first jaw member is configured to engage a distal portion of a first leg member of the surgical clip, the second jaw member is configured to engage a distal portion of a second leg member of the surgical clip, and the stabilizing member is configured to engage a proximal portion of the surgical clip.

12. The clip applier of claim 1 , wherein the stabilizing member is constrained to longitudinal movement between the distal and proximal positions.

13. The clip applier of claim 1 , wherein actuating the actuating member, pivoting the at least one of the first and second jaw members to the closed configuration, and moving the stabilizing member from the distal position to the proximal position are performed simultaneously.

14. A method of applying a surgical clip with a clip applier, the method comprising:

receiving the surgical clip between first and second jaw members of the clip applier;

engaging a proximal portion of the surgical clip with a stabilizing member in a distal position at least partially between the first and second jaw members;

moving an actuating member to pivot at least one of the first and second jaw members toward a closed configuration to close the surgical clip; and

moving the stabilizing member from the distal position to a proximal position at least partially between the first and second jaw members by actuation of the stabilizing member by sliding a pin of at least one of the first and second jaw members through a slot in the stabilizing member, such that pivoting the at least one of the first and second jaw members toward the closed configuration actuates movement of the stabilizing member toward the proximal direction.

15. The method of claim 14 , further comprising disengaging the surgical clip from the stabilizing member when the stabilizing member is in the proximal position.

16. The method of claim 14 , further comprising receiving the proximal portion of the surgical clip between first and second walls of the stabilizing member to stabilize the proximal portion of the surgical clip.

17. The method of claim 14 , further comprising actuating a linkage with the actuating member to pivot at least one of the first and second jaw members.

18. The method of claim 14 , further comprising receiving the stabilizing member in a first inner channel of the first jaw member and a second inner channel of the second jaw member in the closed configuration.

19. The method of claim 14 , further comprising engaging a distal portion of a first leg member with the first jaw member and a distal portion of a second leg member with the second jaw member.

20. The method of claim 14 , wherein moving the stabilizing member is constrained to longitudinal movement between the distal and proximal positions.

21. The method of claim 14 , wherein moving the actuating member, pivoting the at least one of the first and second jaw members to the closed configuration, and moving the stabilizing member from the distal position to the proximal position are performed simultaneously.
