Abstract: In the broader aspects of the invention, there is provided a cleaning tool for electrically and pneumatically powered surgical instruments having either a pneumatic hose connector or an electrical plug connector thereon comprising a tool body having opposite ends. An instrument connector is at one of the ends. A handle is at the other of the ends. The handle allows positive control of the positioning of the surgical instrument and positive control over both axial movement and rotary movement of the instrument during cleaning.

Abstract: A hand held battery powered tool having a motor with a rotor within a stator having stator windings and a motor control trigger operably movable between off and enable positions with means for sensing the trigger position and proving an output signal indicating trigger movement to the off position and means responsive to the output signal for shorting the motor windings and dissipating the kinetic energy of the rotating rotor as heat. A method of retarding rotation of the rotor of the motor comprising the steps of sensation of motor operation command and shorting the motor windings upon sensing the motor operation command while continuing electronic commutation of the motor windings is also provided.
