Abstract
A tubing cassette and method for use in cooling a surgical handpiece. The handpiece is provided with a drive motor which is received within a cooling chamber adapted to circulate cooling fluid around the motor. The cooling chamber is accessible from the exterior of the handpiece via inflow and outflow apertures, and a disposable cassette is selectively attachable to the exterior of the handpiece so as to communicate inflow and outflow apertures of the cassette with the inflow and outflow apertures on the handpiece body. The cassette is provided with inflow and outflow ports in communication with its inflow and outflow apertures in order to direct cooling fluid into and out of the cooling chamber via tubes through which coolant fluid may be circulated with the aid of an external pump, if desired.
