Electrically self-powered surgical instrument with manual release
First Claim
1. An electrically operated surgical instrument, comprising:
- a surgical end effector having an actuation assembly operable to effect a surgical procedure when actuated, a part of said actuation assembly operable to move between a start position and a fully actuated position; and
a handle connected to said end effector for actuating said actuation assembly, said handle having;
a self-contained power supply disposed entirely within said handle;
a drive assembly disposed entirely within said handle and having;
an electrically powered motor; and
a controller electrically connected to said power supply and to said motor and selectively operating said motor;
a transmission mechanically connecting said motor to said moving part and being operable to selectively displace said moving part anywhere between said start and fully extended positions when said motor is operated; and
a manual release mechanically coupled to said transmission to selectively interrupt said transmission and, during interruption, displace said moving part towards said start position independent of operation of said motor.

Abstract
An electrically operated surgical instrument includes a surgical end effector having an actuation assembly effecting a surgical procedure when actuated and a handle connected to the end effector for actuating the assembly. A part of the assembly moves between start and fully actuated positions. The handle has a self-contained power supply and a drive assembly disposed entirely within the handle. The drive assembly has an electrically powered motor and a controller electrically connected to the power supply and to the motor. The controller selectively operates the motor. A transmission mechanically connects the motor to the moving part and selectively displaces the moving part anywhere between the start and fully extended positions when the motor is operated. A manual release is mechanically coupled to the transmission to selectively interrupt the transmission and, during interruption, displaces the moving part towards the start position independent of motor operation.
