Endoscopic surgical clip applier
First Claim
1. A method of applying surgical clips from a surgical clip applier, the method comprising the steps of:
- providing a surgical clip applier comprising at least a plurality of clips, jaws configured to receive and form said clips, a trigger configured to actuate the jaws between an open position for receiving said clips and a closed position for forming said clips, and a wedge plate positionable between the jaws and being movable in a distal and a proximal direction;
providing a drive bar connected to the trigger and a pusher bar selectively connected to the drive bar;
actuating the trigger from an open position to a closed position to (1) load a first clip into the jaws and to move the jaws from the open position to the closed position to form said first clip, and (2) distally move the drive bar and the pusher bar; and
thenreleasing the trigger to return the trigger to the open position, to move the wedge plate in the distal direction between the jaws, and to return the jaws to the open position.

Abstract
An apparatus for application of surgical clips is provided and includes a lockout system selectively engagable with a pusher bar to prevent the pusher bar from returning to a home position and to prevent a trigger from completing a full stroke when a plurality of clips are substantially exhausted. The apparatus may include a trip mechanism including a trip lever biased into contact with the pusher bar, wherein distal movement of the drive bar moves the trip mechanism until the trip lever engages a lip of the pusher bar and in turn distally moves the pusher bar. The apparatus may include a wedge plate including a distal end placeable between spaced-apart jaw members, wherein the wedge plate is moved proximally to withdraw the distal end thereof from between the jaw members when a drive channel is moved in a distal direction.
