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.
