摘要：
A surgical instrument is disclosed. The surgical instrument comprises a handle, a shaft comprising a proximal portion extending from the handle and a distal portion, and a firing member. The surgical instrument further comprises a motor, wherein the motor is configured to be operated in a first direction to advance the firing member toward the distal portion during a firing stroke, wherein the firing stroke comprises a firing stroke end, and wherein the motor is configured to be operated in a second direction to retract the firing member away from the distal portion. The surgical instrument further comprises a switch configured to detect when the firing member has reached the firing stroke end, wherein the motor is configured to be automatically operated in the second direction when the switch detects the firing stroke end.
