    摘要: 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 performing a surgical procedure, such as an ophthalmic or otic surgical procedure. A portion of the second tube may 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 heating filament or a laser to heat the surgical fluid within the boiling chamber, thereby creating a pressure wave that travels down the second tube.
