1. 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; anda 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; anda 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. 2. The instrument according to claim 1, wherein: the first position is a starting position; andthe second position is a fully actuated position. 3. The instrument according to claim 1, further comprising a controller electrically connected to the power supply and to the motor and selectively operating the motor. 4. The instrument according to claim 3, wherein the controller comprises a multi-state switch that causes rotation of the motor in a forward direction when the switch is in a first state and causes rotation of the motor in a reverse direction when the switch is in a second state. 5. The instrument according to claim 3, wherein the transmission has a motor drive side and an actuation side and the manual release mechanism is coupled therebetween. 6. The instrument according to claim 5, wherein: the motor drive side has a series of rotation-reducing gears including a last gear;the actuation side has: at least one gear; anda rack-and-pinion assembly coupled to the at least one gear and directly connected to at least a portion of the moving part; andthe manual release mechanism is mechanically coupled between the at least one gear and the last gear. 7. The instrument according to claim 6, wherein: the motor has an output gear; andthe series of gears has a first stage coupled to the output gear. 8. The instrument according to claim 7, wherein: the series of rotation-reducing gears includes first, second, and third stages, and a cross-over gear with a shaft crossing from the motor drive side to the actuation side; andthe cross-over gear is coupled to the third stage. 9. The instrument according to claim 6, wherein: the series of rotation-reducing gears has a cross-over gear with a cross-over shaft crossing from the motor drive side to the actuation side;the cross-over gear is coupled to the series of rotation-reducing gears;a castle gear is rotationally fixedly coupled about the cross-over shaft and longitudinally translatable thereon, the castle gear having castellations extending towards the actuation side;the at least one gear of the actuation side includes a first pinion having castellation slots shaped to mate with the castellations;a bias device is disposed between the cross-over gear and the castle gear and imparts a bias upon the castle gear towards the actuation side to permit selective engagement of the castle gear with the first pinion and, thereby, cause a corresponding rotation of the first pinion with rotation of the cross-over shaft when so engaged; andthe manual release mechanism has a release part shaped and positioned to provide an opposing force to overcome the bias on the castle gear and disengage the castle gear from the first pinion when the manual release mechanism is at least partially actuated. 10. The instrument according to claim 9, wherein the at least one gear of the actuation side includes a second pinion stage having: a second pinion shaft;a second pinion gear coupled to the first pinion and rotationally fixedly to the second pinion shaft; anda third pinion rotationally fixed to the second pinion shaft, the third pinion being a pinion of the rack-and-pinion assembly and longitudinally moving a rack thereof when rotated. 11. The instrument according to claim 9, wherein the manual release mechanism has: a rest state in which the release part provides the opposing force at a magnitude less than the bias to the castle gear;a first partially actuated state in which the release part provides the opposing force at a magnitude greater than the bias to the castle gear and move the castellations out from the castellation slots; anda second partially actuated state in which the manual release mechanism rotates the first pinion to move a rack longitudinally in a withdrawing direction. 12. The instrument according to claim 9, wherein: the at least one gear of the actuation side includes at least one release gear; andthe first pinion is directly connected to the at least one release gear to rotate the at least one release gear when rotated. 13. The instrument according to claim 12, wherein: the manual release mechanism includes a manual release lever: rotatably connected to the handle; andhaving a one-way ratchet assembly; andthe at least one release gear has an axle directly connected to the ratchet assembly to rotate in a corresponding manner with the manual release lever when the manual release lever is at least partially actuated and to rotate independent of the manual release lever when the manual release lever is not actuated. 14. The instrument according to claim 9, wherein: the at least one gear of the actuation side includes first and second stage release gears; andthe first pinion is directly connected to the first stage release gear to rotate the first and second stage release gears when rotated. 15. The instrument according to claim 1, wherein the manual release mechanism is mechanically coupled to the transmission. 16. The instrument according to claim 1, wherein the manual release mechanism is mechanically disposed in the transmission. 17. The instrument according to claim 1, wherein: the surgical end effector is an endoscopic surgical stapler and tissue cutter; andthe moving part is comprised of at least a staple-actuating and tissue-cutting slide. 18. The instrument according to claim 1, wherein the power supply is a removable battery.
