A self-contained powered surgical stapling device is provided which includes an elongate body and a disposable cartridge assembly detachably supported in a distal end portion of the body. The cartridge assembly includes a frame configured to engage the distal end portion of the body, a housing supported within the frame and containing a plurality of surgical fasteners, an anvil mounted for movement with respect to the housing, an actuation assembly configured to translate relative to the housing and the anvil to progressively move the anvil from an open position to a closed position and to sequentially eject the surgical fasteners from the housing to be formed against the anvil, and an axial drive screw mounted in the frame and threadably associated with the actuation assembly for effectuating the longitudinal translation thereof. A motor assembly having an axial drive shaft is disposed within the elongate body, and a coupling is provided for detachably connecting the axial drive shaft and the axial drive screw. A power source is disposed within the elongate body for energizing the motor assembly.
[ What is claimed is:] [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 assembly detachably supported in a distal end portion of the elongate body, and including:i) a frame havin
[ What is claimed is:] [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 assembly detachably supported in a distal end portion of the elongate body, and including:i) a frame having a proximal end portion configured to engage the distal end portion of the elongate body;ii) a housing supported within the frame and containing a plurality of surgical fasteners;iii) an anvil pivotably associated with the frame and mounted for movement with respect to the housing between an open position and a closed position;iv) an actuation assembly configured to translate in a longitudinal direction relative to the housing and the anvil to progressively move the anvil from the open position to the closed position and to sequentially eject the surgical fasteners from the housing to be formed against the anvil; andv) an axial drive screw rotatably mounted within the frame and threadably associated with the actuation assembly for effectuating the longitudinal translation thereof;c) a motor assembly disposed within the elongate body and including an axial drive shaft;d) a coupling disposed within the elongate body for detachably connecting the axial drive shaft of the motor assembly and the axial drive screw of the cartridge assembly; ande) a power source disposed within the elongate body for energizing the motor assembly.
