IMPROVED MOTOR CONTROL AND FEEDBACK IN POWERED SURGICAL DEVICES
Surgical devices and methods are described herein that provide improved motor control and feedback, thereby combining advantages of manually-operated and powered surgical devices. In one embodiment, a surgical device includes a proximal handle portion (10) that includes a motor, a distal end effector (14) coupled to the handle portion, and a cutting element configured to cut tissue engaged by the end effector (14), wherein the motor is configured to supply power that moves the cutting element. The device also includes a motor control mechanism configured to cause the amount of the power to dynamically change in response to a manual user input when the cutting element is moving.
