Abstract

An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft, surgical fasteners disposed in the elongated shaft, a firing system for dispensing the surgical fasteners, a firing rod disposed within the elongated shaft and movable within a first plane, and an advancer disposed within the elongated shaft and moveable within a second plane. An actuator is coupled with the advancer for moving the advancer back and forth between retracted and extended positions. A staging assembly at the distal end of the elongated shaft aligns a leading surgical fastener with the first plane. The staging assembly includes a biasing device that is configured to be deflected away from the first plane by the advancer when the advancer is in the extended position and the staging assembly is configured to spring back into alignment with the first plane when the advancer returns back to the retracted position.
