摘要：
A surgical instrument includes a drive shaft, a motor for rotating the drive shaft, and a motor speed control. The motor speed control includes a first switch and a second switch which are in communication with the motor. The first switch is disposed over and in registration with the second switch. The first switch has an activated state such that the first switch sends a first signal to the motor. The motor rotates the drive shaft in response to the first signal. The second switch sends a second signal to the motor that varies the speed that the motor rotates the drive shaft in response to a force applied to the second switch by the first switch.
