Abstract
A surgical instrument comprising a motor assembly, a shaft defining a shaft axis, a distal head, a rotary drive member, and a distal head lock member movable between a first position where the distal head is unlocked from the shaft and a second position where the distal head is locked to the shaft is disclosed. The motor assembly comprises a motor and a controller configured to operate the motor in first and second operating modes. The distal head comprises an end effector movable between an open configuration and a closed configuration. The distal head is rotated about the shaft axis when the distal head lock member is in the first position and the rotary drive member is actuated. The end effector is moved from the open configuration toward the closed configuration when the distal head lock member is in the second position and the rotary drive member is actuated.
