US 10,517,610 B2 · Auxiliary unit for surgical tool

Abstract

A powered surgical tool that includes a housing with a head and a handle that extends from the head. An electric motor is disposed in the head. A trigger extends from the handle. There is a void space in the handle. A plate separates the motor from the handle. Internal to the handle void space there is a rotor sensor and a control circuit. The rotor sensor is able to monitor the magnetic fields emitted by the motor rotor and that pass through the plate. The control circuit receives signals from the rotor sensor representative of the rotational orientation of the rotor and is further able to monitor the actuation of the trigger. Based on the rotor orientation signals and the actuation of the trigger, the control circuit generates signals that result in the selective generation of power signals to the motor rotor.
