摘要：
A motorized surgical instrument is provided. The surgical instrument includes a displacement member. A motor is coupled to the displacement member. A control circuit is coupled to the motor. A position sensor is coupled to the control circuit. A timer circuit is coupled to the control circuit to measure elapsed time. The control circuit is configured to receive the position of the displacement member from the position sensor, receive elapsed time from the timer circuit, and control velocity of the motor based on the position of the displacement member and the elapsed time. A method of controlling motor velocity of the surgical instrument also is disclosed.
