Electrically Self-Powered Surgical Instrument With Manual Release

Abstract

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.

Dependencies are inferred from the claim text.
