Patent ID: 7422139

Claim:
A surgical cutting instrument comprising: an end effector comprising a moveable cutting instrument for cutting an object positioned in the end effector, wherein the end effector comprises; an elongate channel for carrying the cutting instrument and a staple cartridge; and an anvil pivotably connected to the elongate channel; a main drive shaft assembly connected to the end effector; and a handle connected to the main drive shaft assembly, wherein the handle comprises: a gear drive train connected to the main drive shaft assembly; an electric main motor for actuating the gear drive train; a battery for powering the motor; a firing trigger for actuating the main motor; and a tactile position feedback system for applying force to the firing trigger such that position of the firing trigger is related to the position of the cutting instrument in the end effector; and a run motor sensor for sensing retracting of the firing trigger, wherein, when retraction of the firing trigger is sensed by the run motor sensor, the main motor is signaled to forward rotate to cause cutting of the object positioned in the end effector by the cutting instrument.
