  • Patent number: 6331171
    Abstract: A tip for a liquefraction surgical handpiece uses at least two tubes. One tube is used for aspiration and another, smaller 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 so that heated fluid escaping the injection tube is reflected off of the internal wall of the aspiration tube prior to entering the eye. The internal wall is textured or roughened to further diffract the fluid stream. Such an arrangement prevents the injected fluid from directly entering the eye. The handpiece may also contain other tube, for example, for injecting relatively cool surgical fluid.

  • Patent number: 6319223
    Abstract: A cassette configuration, operative parts of which may be disposable or resterilizable, is configured with an adapter that may be mounted within the cassette receiving portal of a console that uses a peristaltic pump spaced apart from actuator and vent controls to engage the lower end wall of a cassette. The adapter is asymmetrically mounted in the available space, and allows a tubing loop from one side of a cassette inserted under it to be threaded through the peristaltic pump and to be seated in a bore in the adapter on the opposite side. A lower edge of the cassette fits into an interface slot in the console, and the interior tubing configuration enables clamping of irrigation and vent lines, while providing aspiration and irrigation flows to and from a handpiece. Within the cassette or in the console, flow control elements are provided to enable alternative venting of either air or fluid into the aspiration system to prevent excessive suction at the operative site.
