摘要：
A phacoemulsification cannula (10) includes a hub (12) for engagement with anophthalmic surgical instrument. An elongated needle (14) having a proximalend (16) is attached to the hub (12). The cannula (10) has an aspiration lumen (20)spanning a majority of a length of a needle (14) from the proximal end towards adistal end (18). A venturi lumen (22) is formed in the needle adjacent the distalend. The venturi lumen (22) is in communication with the aspiration lumen (20)so that fluid and tissue may be aspirated through the venturi lumen (22) and theaspiration lumen (20).
