The motor is configured for operative connection to a power source. A surgical attachment has a proximal end detachably connected to the motor and a distal end defining a working plane for engagement with biological tissue. A housing has a housing distal end, a housing proximal end, and a cavity configured to receive the motor and the surgical attachment. An irrigation path of the housing is configured to communicate irrigation fluid. The irrigation path has an inlet proximate the housing proximal end operatively connected to an irrigation fluid source, and an outlet proximate to the working plane.
