Abstract
A surgical tool for resecting bone has a pneumatic motor within a tool body which rotates a coaxial tool implement. The tool implement is provided with irrigation fluid from a fluid reservoir. The reservoir and the motor are charged with pressurized air from a pressurized air source. A fluid control valve is located between the reservoir and the tool, and an air control valve is located between the air pressure source and the motor. The air control valve is controlled by a variable foot pedal or hand valve so that the speed of the motor is variably actuated by the foot valve.
