MOTOR-DRIVEN SURGICAL CUTTING AND FASTENING INSTRUMENT WITH TACTILE POSITION FEEDBACK
First Claim
1. A surgical cutting and fastening instrument comprising:
- an end effector comprising a moveable cutting instrument for cutting an object positioned in the end effector;
a main drive shaft assembly connected to the end effector;
a gear drive train connected to the main drive shaft assembly;
a main motor for actuating the gear drive train;
a firing trigger for actuating the main motor; and
a tactile position feedback system for applying force to the firing trigger such that the position of the firing trigger is related to the position of the cutting instrument in the end effector.

Abstract
A surgical cutting and fastening instrument is disclosed. According to various embodiments, the instrument includes an end effector comprising an elongate channel, a clamping member pivotably connected to the channel, and a moveable cutting instrument for traversing the channel to cut an object clamped in the end effector by the clamping member when the clamping member is in a clamped position. The instrument may also comprise a main drive shaft assembly for actuating the cutting instrument in the end effector, a gear drive train connected to the main drive shaft assembly, and a motor for actuating the gear drive train. The instrument may also includes a closure trigger and a firing trigger, separate from the closure trigger, for actuating the motor when the firing trigger is retracted. Also, the instrument may comprise a mechanical closure system connected to the closure trigger and to the clamping member for causing the clamping member to pivot to the clamped position when the closure trigger is retracted.

17. A surgical cutting and fastening instrument comprising:
-
an end effector comprising a moveable cutting instrument for cutting an object positioned in the end effector; 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; a main motor for actuating the gear drive train; 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. - View Dependent Claims (18, 19)
