Abstract

A clip applier configured to apply a surgical clip to tissue. The clip applier may include first and second jaw members configured to engage distal portions of the surgical clip. The first and second jaw members may be configured to move relative to each other between an open configuration and a closed configuration. The clip applier may also include a stabilizing member having an end portion secured to the first jaw member. The stabilizing member may be configured to engage a proximal portion of the surgical clip and be compressed from a first configuration when the first and second jaw members are in the open configuration to a second configuration when the first and second jaw members are in the closed configuration. The stabilizing member may have at least one bend that facilitates compression of the stabilizing member.

First claim

What is claimed is:

1. A clip applier configured to apply a surgical clip to tissue, the clip applier comprising:
first and second jaw members configured to engage distal portions of the surgical clip, the first jaw member having a longitudinal channel in an inner portion extending along a longitudinal axis of the clip applier, and the first and second jaw members being configured to move relative to each other between an open configuration and a closed configuration; and
a stabilizing member received in the longitudinal channel of the first jaw member and having an end portion secured to the first jaw member, the stabilizing member having an aperture and/or first and second walls configured to receive a proximal portion of the surgical clip to reduce lateral movement of the surgical clip,
wherein the stabilizing member is flexible and configured to be compressed from a first configuration when the first and second jaw members are in the open configuration to a second configuration when the first and second jaw members are in the closed configuration.

2. The clip applier of claim 1 , wherein the stabilizing member comprises the first and second walls, the first and second walls extend along the longitudinal axis of the clip applier and define a cavity therebetween configured to receive the proximal portion of the surgical clip.

3. The clip applier of claim 1 , wherein the stabilizing member comprises the aperture configured to receive the proximal portion of the surgical clip and to reduce lateral movement of the surgical clip.

4. The clip applier of claim 1 , wherein the stabilizing member comprises at least one bend that facilitates compression of the stabilizing member when the first and second jaw members close.

5. The clip applier of claim 1 , wherein the longitudinal channel is configured to receive the stabilizing member when compressed.

6. The clip applier of claim 1 , wherein the second jaw member has a channel in an inner portion that receives the stabilizing member, and the stabilizing member has a second end portion secured to the second jaw member.

7. The clip applier of claim 1 , further comprising a second stabilizing member having an end portion secured to the second jaw member, wherein the second stabilizing member is configured to be compressed from a first configuration when the first and second jaw members are in the open configuration to a second configuration when the first and second jaw members are in the closed configuration.

8. The clip applier of claim 1 , wherein the end portion of the stabilizing member is secured in the longitudinal channel of the first jaw member.

9. The clip applier of claim 1 , wherein the end portion of the stabilizing member is releasably secured to the first jaw member.

10. The clip applier of claim 9 , wherein the end portion of the stabilizing member comprises an enlarged end configured to snap into the first jaw member.

11. The clip applier of claim 1 , wherein the stabilizing member comprises a spring element.

12. The clip applier of claim 1 , wherein the stabilizing member comprises a plastic element.

13. A stabilizing member configured to be received between first and second jaw members of a clip applier and engage a proximal portion of a surgical clip, the stabilizing member comprising:
a first portion having an enlarged end portion configured to be secured in a longitudinal channel in an inner portion of a first jaw member;
a second portion having an enlarged end portion configured to be secured in a longitudinal channel in an inner portion of a second jaw member;
a first bend and a second bend configured to facilitate compression of the stabilizing member when the first and second jaw members are in a closed configuration, the first bend positionable between a longitudinal axis of the clip applier and the first jaw member, and the second bend positionable between the longitudinal axis of the clip applier and the second jaw member; and
an aperture and/or first and second walls between the first and second portions configured to receive a proximal portion of the surgical clip and to reduce lateral movement of the surgical clip.

14. The stabilizing member of claim 13 , comprising the first and second walls, the first and second walls being longitudinal and defining a cavity configured to receive the proximal portion of the surgical clip.

15. The stabilizing member of claim 13 , wherein the first bend is on a first side of the aperture and the second bend is on a second side of the aperture.

16. The stabilizing member of claim 13 , wherein the stabilizing member comprises a spring element.

17. The stabilizing member of claim 13 , wherein the stabilizing member comprises a plastic element.

18. A method of securing a surgical clip to a clip applier having first and second jaw members, the method comprising:
securing a stabilizing member between the first and second jaw members by engaging a first end portion of the stabilizing member in a longitudinal channel in an inner portion of the first jaw member extending along a longitudinal axis of the clip applier and engaging a second end portion of the stabilizing member in a longitudinal channel in an inner portion of the second jaw member extending along the longitudinal axis of the clip applier;
receiving the surgical clip between the first and second jaw members; and
stabilizing the surgical clip with the stabilizing member to the clip applier by receiving a proximal portion of the surgical clip in an aperture and/or between first and second walls.

19. The method of claim 18 , wherein stabilizing the surgical clip with the stabilizing member includes receiving the proximal portion of the surgical clip into the aperture of the stabilizing member.

20. The method of claim 18 , further comprising:
engaging a distal portion of a first leg member of the surgical clip with the first jaw member; and
engaging a distal portion of a second leg member of the surgical clip with the second jaw member.
