1. A surgical instrument, comprising:
a motor assembly comprising a motor and a motor controller, wherein the motor controller is configured to operate the motor in a first operating mode and a second operating mode;
a shaft defining a shaft axis;
a distal head extending from the shaft, wherein the distal head is rotatable about the shaft axis, and wherein the distal head comprises an end effector movable between an open configuration and a closed configuration;
a rotary drive member operably responsive to the motor, wherein the rotary drive member is operably engaged with the distal head; and
a distal head lock member manually 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, wherein the distal head is rotated about the shaft axis relative to the shaft when the distal head lock member is in the first position and the rotary drive member is actuated, and wherein 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.
