摘要

MODULAR SURGICAL INSTRUMENT WITH CONTAINED ELECTRICAL OR MECHANICAL SYSTEMS A surgical instrument (10) comprising a handle module (12) including at least one handle having a gripping surface and a post disposed within the handle module. The surgical (10) instrument also having a drive assembly (74) selectively removable from the handle module. The drive assembly including a housing; an elongated shaft defining a longitudinal axis extending from the housing; an end effector disposed at a distal end of the elongated shaft, the end effector including a pair of jaw members, at least one of the jaw members movable relative to the otherjaw member between an open position and a closed position; a drive member extending at least partially though the elongated shaft, the drive member operably coupled to the end effector to induce movement of the jaw members between the open position and the closed position in response to longitudinal reciprocation of the drive member; a motor disposed within the housing, the motor operable to move the drive member longitudinally through the elongated shaft; an actuator supported on the housing, the actuator operable to activate the motor; and a slot defined within the housing, wherein the post disposed within the handle is configured to mechanically engage the slot in the housing.
