A surgical instrument including a band configured to move a cutting member within an end effector. The instrument can further include a reel, wherein at least a portion of the band can be wound around the reel, and wherein the cutting member can be configured to unwind the band from the reel when the cutting member is advanced within the end effector. The instrument can further include a first actuator selectively engageable with the reel to rotate the reel, wind the band around the reel, and retract the cutting member. The instrument can further include a second actuator engageable with the reel in the event that the first actuator cannot rotate the reel. |
