摘要:
A surgical instrument that includes a motor powered drive unit that drives a portion of a firing member assembly in an axial direction to actuate a surgical end effector coupled to the instrument. The instrument may further include a retraction system configured to interact with the firing member assembly to permit a clinician to manually retract the portion of the firing member assembly should it become jammed or inadvertently stopped during a firing process. The surgical instrument includes a locking arrangement that interfaces with the retraction system and the motor powered drive unit to prevent the transfer of the retraction forces generated by the retraction system to the motor shaft without physically separating portions of the motorized drive unit.
