MULTIPLE PROCESSOR MOTOR CONTROL FOR MODULAR SURGICAL INSTRUMENTS
First Claim
Patent Images
1. A modular motor control system comprising:
- a master controller;
a first motor configured to control a first movement of a surgical instrument; and
a first motor controller operatively coupled to the first motor, wherein the first motor controller and the master controller are in electrical communication, wherein the master controller provides a first control signal to the first motor controller, wherein the first motor controller controls the first motor in response to the first control signal.

Abstract
In various forms, the modular motor control system may comprise one or more motor controllers each having an associated motor. The one or more motor controllers may be in communication with a master controller. The master controller is configured to provide control signals to the motor controllers to control the associated motors. In some forms, the one or more motor controllers and the associated motors may be located within a surgical module. The surgical module may provide a communications interface between the master controller and the one or more motor controllers.

22. A method for controlling a motor-driven surgical instrument, the method comprising:
-
generating, by a master controller, a plurality of control signals; transmitting, by the master controller, a first subset of the plurality of control signals to a first motor controller; controlling, by the first motor controller, a first motor, wherein the first motor controls a first function of the motor-driven surgical instrument, and wherein the first motor is controlled in response to the first subset of the plurality of control signals. - View Dependent Claims (23, 24)
