摘要： A powered surgical apparatus (10) for applying surgical fasteners to body tissue comprising: a) an elongate body (20) supported by said elongate body; b) a channel (32) supported by said elongate body; c) a cartridge (44) retained by said channel, the cartridge housing a plurality of surgical fasteners (48); d) an anvil member (64) mounted for movement with respect to the cartridge, the anvil and cartridge being relatively movable between an open position and a closed position; e) a motor assembly (86) having a rotatable drive shaft (88); f) a power source (98) for energizing the motor assembly; and g) an actuating assembly (42) driven by the motor assembly, the actuating assembly having a camming beam (100) configured to translate through the cartridge to eject the surgical fasteners therefrom, the camming beam being driven by a drive member 880) and an axial drive screw (84), the drive member defining a threaded bore (82) threadably associated with the axial drive screw, the axial drive screw being connected to the drive shaft; and h) the camming beam having an upper portion (102) for engaging the anvil member and a lower portion (106) for engaging the channel to effect the progressive closure of the anvil member and balance the forces exerted on the anvil member.
