Abstract:
1. A surgical clip applier, comprising: an elongate shaft having opposed jaws formed on a distal end thereof; a clip track extending through the shaft and adapted to retain a plurality of clips; and a feeder shoe slidably disposed within the clip track and adapted to advance the plurality of clips through the clip track, the feeder shoe having a first deflectable tang formed thereon biased against the clip track and configured to prevent proximal movement of the feeder shoe within the clip track, a second deflectable tang formed thereon and configured to be engaged by a feed bar to advance the feeder shoe distally, and a distal end of the feeder shoe having a notch for seating a proximal-most clip of the plurality of clips, the feeder shoe being configured to resist unintentional movement of the feeder shoe by generating friction against the clip track through contact therewith before the feeder shoe is advanced, and the feeder shoe including at least one protrusion formed thereon and in contact with the clip track to generate friction with the clip track.
