Electrically Self-Powered Surgical Instrument With Manual Release
First Claim
1. A method for operating a surgical instrument, which comprises:
- mechanically coupling a manual release to a transmission of a surgical instrument having a self-contained power supply disposed entirely within a handle thereof, the transmission translating movement of an electrically powered motor inside the handle to movement of a part of a surgical end effector connected to the handle, the part being operable to move anywhere between a start position and a fully actuated position; and
selectively interrupting the transmission with the manual release to move the part towards the start position independent of motor operation.

Abstract
A method for operating a surgical instrument includes mechanically coupling a manual release to a transmission of a surgical instrument having a self-contained power supply disposed entirely within a handle thereof. The transmission translates movement of an electrically powered motor inside the handle to movement of a part of a surgical end effector connected to the handle. The part is operable to move anywhere between a start position and a fully actuated position. The method further includes selectively interrupting the transmission with the manual release to move the part towards the start position independent of motor operation.

11. A method for operating a surgical instrument, which comprises:
-
providing a surgical end effector at a distal end of a surgical instrument handle, the end effector having an actuation assembly operable to effect a surgical procedure when actuated, the actuation assembly having a part operable to move between a start position and a fully actuated position; disposing a self-contained power supply and an electrically powered motor entirely within a handle and connecting a motor controller to the motor and to the power supply to selectively operate the motor with the motor controller; mechanically connecting the motor to the moving part through a transmission operable to selectively displace the moving part anywhere between the start and fully extended positions when the motor is operated; and mechanically coupling a manual release to the transmission to selectively interrupt the transmission and, during interruption, displace the moving part towards the start position independent of motor operation. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
