Abstract
A quick release tip assembly for a liquefaction surgical handpiece. The tip contains a lumen attached to a hub. The hub has a circumferential flange around its base. The handpiece contains a recess into which the hub fits. The bottom of the recess contains a plurality of movable snaps or catches that as sized to capture the flange on the tip hub. A slidable lever is connected to the snaps so that movement of the level causes the snaps to spread apart, thereby releasing the flange and allowing the tip to be easily removed from the handpiece.
