ABSTRACT:
An irrigating and aspirating handpiece for use in ophthalmic surgery includes a tubular body having a flexible irrigating sleeve mounted on a distal end thereof, a rigid tubular aspirating tip member mounted in a tip support insert disposed in the distal end of the body and extending through the irrigating sleeve, a length of flexible irrigating tubing connected with a coupling mounted on the proximal end of the body for supplying irrigating fluid through the body, a passage in the tip insert member and the irrigating sleeve to exit at a port in the distal end of the irrigating sleeve, and a length of flexible aspirating tubing extending within the irrigating tubing and connected with the proximal end of the aspirating tip member within the body for aspirating material entering through a port in the distal end of the aspirating tip member. The irrigating and aspirating handpiece has a slim, cylindrical configuration to facilitate manipulation by a surgeon with the concentric irrigating and aspirating tubings producing no branch obstructions, and the irrigating and aspirating handpiece is constructed of a minimal number of parts easily produced and assembled to permit the handpiece to be economically disposable.
