1. A surgical clip applier, comprising:

  • a housing having a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof;

    an advancer assembly coupled to the trigger, disposed within the elongate shaft, and configured to advance one of a plurality of clips disposed within the elongate shaft into the opposed jaws, the advancer assembly being movable between a proximal position and a distal position; and

    a feeder shoe disposed within the elongate shaft and having a tang configured to engage the advancer assembly to lock the advancer assembly, and thus the trigger, in respective partially advanced positions to prevent the advancer assembly from moving to the proximal position, and thus to prevent the trigger from moving to a fully opened position, after the advancer assembly has moved to the distal position to advance a proximal-most clip into the opposed jaws.
