Motor-driven surgical cutting instrument
TL;DR: In this paper, a motor-driven surgical cutting and fastening instrument consisting of an end effector, an electric motor, and a motor control circuit is used for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end-effector.
Patent
Motor-driven surgical cutting instrument with electric actuator directional control assembly
TL;DR: A motor-driven surgical instrument having a control assembly for controlling a switch of the instrument can be represented by a motor control circuit, a drive member, and a slider as discussed by the authors.
