ABSTRACT:
A phacoemulsification needle generally includes a needle for fragmenting eye tissue, a sleeve coaxially disposed about the needle for introducing irrigation fluid into a surgical site, and structure on the needle for inhibiting the formation of bubbles and microbubbles as the irrigation fluid flows along an irrigation pathway formed between the needle and coaxial sleeve. The structure includes preferably three wedge shaped indents, each being equidistantly spaced with respect to each other, about a shoulder of the needle. The needle includes a threaded end for enabling its removable engagement with a suitable phacoemulsification horn, the removable engagement being facilitated by surfaces on the wedge shaped indents.
