Surgical fasteners, applicator instruments, and methods for deploying surgical fasteners

摘要

An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft extending from the housing, a firing rod disposed inside the elongated shaft and being movable within a first plane between a retracted position and an extended position, an advancer disposed inside the elongated shaft and being moveable within a second plane between a retracted position and an extended position, and a staging assembly located adjacent the distal end of the elongated shaft and being adapted to align surgical fasteners with a distal end of the firing rod. The staging assembly is held below the second plane by the advancer when the advancer is in the extended position and the staging assembly is adapted to move into at least partial alignment with the distal end of the firing rod when the advancer is in the retracted position.
