Surgical fastener-applying apparatuses with sequential firing

摘要

A surgical fastening instrument is provided. The surgical fastening instrument includes a handle portion and an elongate portion extending distally from the handle portion and defining a longitudinal axis along a length thereof. The surgical fastening instrument also includes an end effector assembly that includes an anvil and a cartridge supported adjacent a distal end of the elongate portion. Each of the anvil and the cartridge includes a tissue contacting surface oriented substantially perpendicular to the longitudinal axis. One or more independently movable pushers is configured to support one or more surgical fasteners. A thrust bar is operatively coupled to the elongate portion, wherein the thrust bar is movable over a predetermined stroke to effect sequential ejection of at least two surgical fasteners of the plurality of surgical fasteners from the cartridge.
