Claim:
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.
