Electrically Self-Powered Surgical Instrument With Manual Release

摘要

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.
