  • Patent number: 6206848
    Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to great an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. 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 annular passage. The electrodes are insulated from each other.

  • Patent number: 6196989
    Abstract: A tip for a liquefracture surgical handpiece. The tip uses at least two channels or tubes. One tube is used for aspiration and at least one other tube is used to inject heated surgical fluid for liquefying a cataractous lens. The distal portion of the injection tube terminates just inside of the aspiration tube and directs the heated fluid through an orifice in the wall of the aspiration tube opposite the injection tube. The handpiece may also contain other tubes, for example, for injecting relatively cool surgical fluid.

  • Patent number: 6186868
    Abstract: A method of polishing articles comprising soft acrylic materials is disclosed. The method includes a polishing step and a cleaning step. In the polishing step a receptacle is charged with polishing beads of various sizes, alumina, sodium hydroxide, water, a surfactant, and the articles to be polished, and agitated for a period of time and at a speed sufficient to remove surface irregularities. The polishing step is completed below the glass transition (Tg) point of the acrylic article being polished but above 0° C. Following the polishing step, the polished articles are cleaned by rinsing them with water for a period of time to clean the surface of the polished articles.

  • Patent number: 6179805
    Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. 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 annular passage. The distal end of the annular gap is sealed by sealing together the distal ends of the first and second tube and a plurality or orifices or ports may be formed near the seal. As the expanding gas is propelled down the annular gap, the gas/liquid stream is forced out of the distal orifices in a controlled and directed manner.

  • Patent number: 6179808
    Abstract: A control system for a surgical system that includes an irrigation fluid flow sensing capability. The sensing capability may be placed in the control console or in the handpiece. Irrigation flow measurements provided by the sensing capability allows the control system to vary irrigation pressure and/or flow, aspiration pressure and/or flow and power supplied to the handpiece more accurately than prior art sensors that monitor aspiration flow.
