1. A self-contained powered surgical apparatus for applying surgical fasteners to body tissue comprising:
- a) an elongate body defining a longitudinal axis;
b) a cartridge supported by said elongate body and housing a plurality of surgical fasteners and having a tissue engaging surface thereon;
c) an anvil member having a fastener forming surface thereon, the anvil member mounted adjacent the cartridge and configured for relative movement between an open position wherein said fastener forming surface is spaced from said tissue engaging surface and a closed position wherein said fastener forming surface is in close cooperative alignment with said tissue engaging surface;
d) a motor assembly disposed within the elongate body;
e) a power source disposed within the elongate body for energizing the motor assembly; and
f) an actuating assembly including a longitudinally translating drive member driven by the motor assembly and first and second camming mechanisms driven by the drive member; and
g) wherein movement of the drive member in a longitudinal direction initially causes the first camming mechanism to effect relative movement of the anvil member and the cartridge and subsequently causes the second camming mechanism to effect sequential ejection of a plurality of surgical fasteners from the cartridge.

Abstract
A self-contained powered surgical stapling device is provided which includes an elongate body. A fastener applying assembly is operatively associated with a distal end of the elongate body and includes a cartridge housing a plurality of staples and an anvil actuable to move between an open position and a closed position. A motor assembly is disposed within the elongate body for driving an actuation assembly configured to translate through the fastener applying assembly to progressively close the anvil and sequentially eject staples from the cartridge.

17. A self-contained powered surgical apparatus for applying surgical fasteners to body tissue comprising:
-
a) an elongate body defining a longitudinal axis and having proximal and distal end portions; b) a cartridge supported by said elongate body and housing a plurality of surgical fasteners and having a tissue engaging surface thereon; c) an anvil member having a fastener forming surface thereon, the anvil member mounted adjacent the cartridge, the anvil member and cartridge being relatively movable between a first position wherein said fastener forming surface is spaced from said tissue engaging surface and a second position wherein said fastener forming surface is in close cooperative alignment with said tissue engaging surface; d) a motor assembly disposed within the elongate body; e) a power source disposed within the elongate body for energizing the motor assembly, the elongate body having a substantially uniform outer diameter along its entire length, such that said proximal and distal end portions have substantially the same diameter; and f) an actuating assembly driven by the motor assembly and mounted for movement in a longitudinal direction to effect sequential ejection of a plurality of surgical fasteners from the cartridge. - View Dependent Claims (18, 19, 20, 21, 22)
