Endoscopic reposable surgical clip applier
First Claim
1. A reposable surgical clip applier, comprising:
- a handle assembly; and
an endoscopic assembly selectively connectable to and in mechanical communication with the handle assembly, the endoscopic assembly including a shaft assembly having;
an outer tube defining a longitudinal axis extending therealong and a pair of transverse channels formed therein;
a pusher bar slidably supported within the outer tube, wherein a proximal portion of the pusher bar is received within the pair of transverse channels; and
a spindle assembly slidably supported within the outer tube, a surface of the spindle supporting a fin that is in selective engagement with a proximal portion of the pusher bar,wherein during a distal advancement of the spindle, the fin urges the pusher bar in a distal direction.

Abstract
A reposable surgical clip applier includes a handle assembly and an endoscopic assembly that is selectively connectable to and in mechanical communication with the handle assembly. The endoscopic assembly includes a shaft assembly having an outer tube defining a longitudinal axis extending therealong and a pair of transverse channels formed therein, a pusher bar slidably supported within the outer tube, and a spindle assembly slidably supported within the outer tube. A proximal portion of the pusher bar is received within the pair of transverse channels. A surface of the spindle supports a fin that is in selective engagement with a proximal portion of the pusher bar such that during a distal advancement of the spindle, the fin urges the pusher bar in a distal direction.
