Abstract
A system and method for provided a phacoemulsification surgery handpiece including a convertible sleeve for phacoemulsification surgery and irrigation/aspiration procedures. In a retracted state, the sleeve is in a desired relationship with the exposed portion of a phaco tip of the handpiece to support normal phacoemulsification surgery. In an extended state, the sleeve features a distally placed aspiration hole located forward from the distal end of a phaco tip to allow typical irrigation/aspiration procedures. A distal tip segment of the hand piece is overmolded by polyimide materials having a split feature to allow egress of a phaco tip.
