Clip advancer with lockout mechanism
First Claim
1. A surgical clip applier, comprising:
- an elongate shaft having opposed jaws formed on a distal end thereof;
an advancer assembly 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 in a partially advanced position to prevent the advancer assembly from moving to the proximal position after the advancer assembly has moved to the distal position to advance a proximal-most clip into the opposed jaws.

Abstract
A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one embodiment, a surgical clip applier is provided and can include a housing having a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof. The clip applier can include an advancer assembly disposed within the elongate shaft and configured to advance one of a plurality of clips disposed within the elongate shaft into the opposed jaws. A feeder shoe can be disposed within the elongate shaft and can be configured to engage and prevent the advancer assembly from moving to a proximal position after the advancer assembly has moved to a distal position to advance a proximal-most clip into the opposed jaws. This can indicate to a user that a clip supply of the surgical clip applier is depleted.

9. A method for advancing surgical clips, comprising:
-
moving an advancer assembly distally from a proximal position, through an elongate shaft, and over a feeder shoe in the elongate shaft to a distal position to advance a proximal-most clip of a plurality of clips disposed in the elongate shaft into opposed jaws located at a distal end of the elongate shaft; releasing the proximal-most clip from the opposed jaws of the clip applier, and then moving the advancer assembly proximally over the feeder shoe until a recess in the advancer assembly engages a tang on the feeder shoe to maintain the advancer assembly in an intermediate position located between the proximal and distal positions.
