    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.

    摘要翻译： 具有至少两个流明或管安装到身体的外科手术器械。 至少一个管用于抽吸，并且至少一个其它管用于注射加热的手术流体以执行外科手术，例如眼科或耳外科手术。 第二管的一部分可以形成泵送室。 泵送室通过煮沸少量的手术液来起作用。 当流体沸腾时，其迅速膨胀，从而将泵送室下游的液体推出第二管。 泵送室可以使用加热丝或激光来加热沸腾室内的手术流体，从而产生沿着第二管行进的压力波。

    摘要： A tip assembly for a liquefaction surgical handpiece. The tip assembly has an inner connector and an outer cap. The outer cap contains an external thread for attaching the tip assembly to a handpiece. The inner housing contains an alignment tab and fits within the outer cap so as to allow rotation of the inner connector within the outer cap. The inner and outer liquefaction tip tubes are frictionally fit into a bore in the inner connector. The proximal end of the inner housing contains a gasket that seal the inner housing against the handpiece.

    摘要： A surgical handpiece having a tip with at least two coaxially spaced electrically conductive tubes. The tubes are separated by an electrical insulator. The interior of the inner tube is used for aspiration of liquefied tissue. The outer tube is surrounded by a soft irrigation sleeve that forms an irrigation fluid path. The distal portion of the interior tube terminates inside of the outer tube so as to form a boiling region. Surgical fluid from the irrigation fluid path can enter the boiling region through a hole or port in the outer tube. Electrical current is passed between the inner and outer tube to rapidly boil any surgical fluid in the boiling region. The boiling fluid rapidly expands out of the ring between the tube ends and forces hot fluid to contact the targeted tissue, thereby liquefying the tissue and allowing the tissue to be aspirated. Such a construction allows the boiling chamber to be self-priming and operate even if the outer tube is occluded with material.
