A surgical device is described herein that can be used to fire different types and sizes of disposable loading units. In a preferred embodiment, the device applies parallel rows of surgical fasteners to body tissue and concomitantly forms an incision between the rows of staples during an endoscopic or laparoscopic surgical procedure. The device can be utilized with disposable loading units configured to apply linear rows of staples measuring from about 15 mm in length to about 60 mm in length and can be used to fire disposable loading units containing surgical clips and individual staples. A lockout mechanism is provided to disable the disposable loading units after firing.

[ What is claimed is:] [1.] A surgical stapler comprising:a) a handle assembly including an elongated barrel portion and an actuation handle mounted for manipulation through an actuation stroke cycle which includes a clamping stroke segment and a stapling stroke segment;b) an elongated body extending distally from the barrel portion of the handle assembly and defining a longitudinal axis;c) an elongated actuation shaft supported at least in part within the barrel portion of the handle assembly and mounted for longitudinal movement in response to manipulation of the actuation handle;d) a disposable loading unit operatively engaged at a distal end portion of the elongated body and including a staple cartridge containing a plurality of staples, an anvil mounted adjacent the staple cartridge and movable between an open position and a clamping position, and an actuator which operatively interacts with the elongated actuation shaft and is movable in a distal direction relative to the staple cartridge and anvil to effect movement of the anvil from the open position to the clamped position during said clamping stroke segment and to effect sequential ejection of the staples from the cartridge during the stapling stroke segment; ande) a lockout mechanism mounted in the disposable loading unit and including a lock mounted adjacent the actuator for longitudinal movement therewith and pivotal between an unlocked position and a locked position, fixed support structure in the disposable loading unit for supporting the lock in the unlocked position during the clamping stroke segment of the actuator and projection mounted in the disposable loading unit for engaging the lock in the loaded position upon retraction of the actuator to move the anvil to the open position after firing.
