Abstract:

A hand-held instrument which provides for directing irrigating fluid to a surgical site through an irrigation passage, and which may also provide for suction of fluid and debris away from the surgical site through an alternate passage. The passages are typically tubing channels which may be attached to various types of tips which are introduced at the surgical site. The handpiece instrument, including the tubing channels, may be totally disposable, or the handpiece may be adapted to allow the external housing to be reusable with only the tubing channels being disposable. Both the suction and irrigation tubing channels may be assembled internally in the handpiece housing, with both suction and irrigation being conveniently controlled with one hand by pinch valves. In an alternate embodiment, the handpiece has external mounts for attaching the suction tube, providing the operator of the handpiece the option of having the suction function attached or detached during the surgical procedure.
