Ligating clip advance
First Claim
1. A surgical clip applier for applying a plurality of surgical clips comprising a clip advance for sequentially advancing the plurality of surgical clips, the clip advance comprising:
- a longitudinally extending housing having a first channel for receiving the plurality of surgical clips;
a pusher, andmeans mounting said pusher in the housing for reciprocating longitudinal movement adjacent the plurality of clips, the pusher having a plurality of tabs arranged to correspondingly engage and distally move respective ones of the plurality of clips when said pusher is moved distally;
wherein one of said pusher and housing has a cam and the other of said pusher and housing has a cam surface, the cam and the cam surface configured and arranged relative to each other such that, upon proximal movement of the pusher, the cam and the cam surface interact to move the tabs out of longitudinal contacting alignment with the clips.

13. A surgical clip applier for applying a plurality of surgical clips comprising a clip advance for sequentially advancing the plurality of surgical clips, the clip advance comprising:
-
a longitudinally extending housing having a first channel and a second channel, the first and second channels located in parallel alignment to one another, the first channel for receiving the plurality of surgical clips; a pusher, and means mounting said pusher in the second channel of the housing for reciprocating longitudinal movement adjacent the plurality of clips, the pusher having a plurality of tabs arranged to correspondingly engage and distally move respective ones of the plurality of clips when said pusher is moved distally; wherein one of said pusher and housing has a deflectable member and the other of said pusher and housing has a cam, the deflectable member and the cam configured and arranged relative to each other such that, upon proximal movement of the pusher, the deflectable member and the cam interact to move the tabs out of longitudinal contacting alignment with the clips without deflecting the tabs. - View Dependent Claims (14, 15, 16, 17, 18)
