Abstract
A baffle with holes formed therein is mounted in a sleeve which surrounds the needle of an ultrasonic handpiece so as to reduce bubbles in the irrigation fluid supplied to the handpiece and thus improve the visibility at the operating site. As irrigation fluid is supplied to the handpiece, it contacts the ultrasonic motor which tends to cause bubbles and by providing the baffle with openings, the bubbles are restricted from passing the baffle and obstructing the vision of the surgeon using the ultrasonic handpiece.
