Abstract
A work tip for a surgical hand piece has a solid knife connected to a source of ultrasonic energy in the hand piece and a sleeve having a generally uniform cylindrical shape that surrounds the distal end of the knife. The distal end of the knife has at least a portion of a conical tip, e.g., a Cobra tip. The sleeve provides irrigation and aspiration fluid channels. Also, a structure in the sleeve blocks the proximal opening in the upper part of the conical tip when the knife is withdrawn into the sleeve. A hole is provided in the sleeve adjacent to, but proximally of the structure so that when a portion of the opening is blocked, aspiration fluid flows through the hole to provide I/A clean up.
