ABSTRACT:
A surgical handpiece having at least two lumens or tubes mounted to a body. At least one tube is used for aspiration and at least one other tube is used to inject heated surgical fluid for liquefying a cataractous lens. A portion of the second tube is enlarged to form a pumping chamber. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the second tube. The pumping chamber may use a pair of electrodes.
