A surgical handpiece driver having a pumping chamber. The pumping chamber works by boiling a small volume of a fluid. As the fluid boils, it expands rapidly, thereby propelling a piston down the length of the pumping chamber. The piston may be attached to the operative shaft or rod of a surgical probe and produce reciprocal motion. Alternatively, the piston may be attached to a cam or gear to product rotary motion.
