SURGICAL CLIP APPLIER METHODS
First Claim
Patent Images
1. A method for applying a surgical clip, comprising:
- applying a closing force to a pair of opposed jaws formed on a surgical clip applier, the closing force being effective to move the opposed jaws from an open position to a closed position, wherein the closing force is transferred to an overload mechanism disposed within the surgical clip applier when the closing force is greater than a threshold force of the overload mechanism, the threshold force of the overload mechanism increasing as the jaws are moved from an open position toward the closed position.

Abstract
A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween.

7. A method for advancing a surgical clip through an elongate shaft of a surgical clip applier, comprising:
- distally advancing a feed bar within an elongate shaft of a surgical clip applier to drive a distal-most clip disposed within the elongate shaft into a jaw assembly, and to distally drive a feeder shoe disposed within the elongate shaft and thereby distally advance at least one additional surgical clip disposed within the elongate shaft.

13. A method for applying a surgical clip, comprising:
-
moving a trigger coupled to a housing a first distance toward a closed position to actuate a clip advancing assembly disposed within the housing, thereby advancing a clip into a jaw assembly formed on a distal end of the elongate shaft;
further moving the trigger a second distance toward the closed position to actuate a clip forming assembly disposed within the housing, thereby forming the clip disposed within the jaw assembly, the trigger being pliant relative to the clip advancing assembly during actuation of the clip forming assembly. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
