First Claim
1. A surgical instrument, comprising:
- a surgical end effector having an actuation assembly operable to effect a surgical procedure when actuated, a part of the actuation assembly being movable between a first position and second position; and
a handle connected to the end effector for actuating the actuation assembly, the handle having;
a power supply disposed within the handle;
a motor disposed within the handle and electrically powered by the power supply;
a transmission connecting the motor to the moving part and operational to displace the moving part anywhere between the first and second positions when the motor is operated; and
a manual release mechanism that selectively interrupts the transmission and, during interruption, displaces the moving part towards the first position independent of operation of the motor.
