Patent number: 10751076Abstract: A motor-driven surgical instrument that may comprise (i) a movable drive member that is driven in a first direction when the electric motor operates in a first direction and that is driven in a second direction when the electric motor operates in a second direction. Movement of the drive member causes movement of the movable component of the end effector, and (ii) a motor control circuit connected to the motor for controlling the motor. The motor control circuit may comprise a switching circuit that, upon actuation, reverses the direction of the motor from the first direction to the second direction. The switching circuit may be actuatable separately through each of: (i) actuation of a movable actuator of the switching circuit through movement of the drive member at least in the first direction; and (ii) manual actuation by a user of the surgical instrument.Type: GrantFiled: May 11, 2017Date of Patent: August 25, 2020Assignee: Ethicon LLCInventors: Ryan J Laurent, Brett E. Swensgard, Bret W. Smith
