Abstract
A surgical instrument includes a shell assembly and an adapter. The shell assembly includes a shell housing, a plurality of staples, a staple pusher, a staple actuator configured to engage the staple pusher, a knife member, and a knife carrier supporting the knife member. The adapter includes a staple band operatively coupled to an actuation mechanism for axial displacement, a knife band at least partially received within the staple band, and a cam ring rotatably supported about the knife band. The staple band is configured to releasably engage the staple actuator. The knife band is operatively coupled with an actuation mechanism for axial displacement. The cam ring is rotatable between an engaged position in which the knife carrier engages the cam ring for concomitant axial displacement with the knife band and a disengaged position in which the knife carrier is disengaged from the cam ring.
