First Claim
Patent Images
1. A surgical instrument comprising:
- a motor;
an end effector;
a drive shaft;
a closure trigger, wherein actuation of the closure trigger causes the end effector to clamp an object;
a firing trigger distinct from the closure trigger for actuating the motor;
a run motor sensor capable of communicating with the motor and configured to sense actuation of the firing trigger; and
a tactile feedback system for applying a feedback force to the firing trigger.

Abstract
A surgical instrument is disclosed. The surgical instrument comprises a motor, an end effector, a drive shaft, and a closure trigger, wherein actuation of the closure trigger causes the end effector to clamp an object. The surgical instrument further comprises a firing trigger distinct from the closure trigger for actuating the motor, a run motor sensor capable of communicating with the motor and configured to sense actuation of the firing trigger, and a tactile feedback system for applying a feedback force to the firing trigger.
