1. A surgical stapler comprising:
- a) a handle assembly including a stationary handle and a pivotable handle mounted for manipulation through an actuating stroke;
b) an elongated body extending distally from the handle assembly and defining a longitudinal axis;
c) an actuation member supported within the handle assembly and mounted for linear movement in response to movement of the pivotable handle through the actuation stroke;
d) a staple cartridge supported by the elongated body and containing a plurality of staples;
e) an anvil mounted adjacent the cartridge, the anvil having a fastener forming surface thereon and being mounted for relative movement with respect to the cartridge between an open position spaced from the staple cartridge and a closed position in close cooperative alignment with the staple cartridge; and
f) an actuator operatively connected to the actuation member, the actuator being configured to move relative to the staple cartridge and anvil to initially effectuate relative movement of the anvil and cartridge from an open position to a closed position and to subsequently effectuate sequential ejection of the staples from the cartridge in response to movement of the pivotable handle through the actuation stroke.

Abstract
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.
