Surgical instrument sleeve
First Claim
1. A surgical sleeve for a phacoemulsification surgical instrument comprising:
- a) a hollow sleeve body having a proximal end and a distal end, b) said proximal end having a configuration adaptable to be removably attached to said surgical instrument, c) said distal end having a tubular shank with a truncated cone contour on its extremity, and d) at least one substantially annular protuberant appendage integrally formed with said shank and extending from an outer surface of the distal end for manipulation of intraocular tissue.

Abstract
A surgical sleeve lens removal by laser or ultrasonic surgical instruments, also used on the forefront of an ophthalmic irrigation/aspiration surgical instrument. The surgical sleeve consists of a hollow sleeve body (20) with its proximal end (22) adapted to fit the surgical instrument and its distal end (24) having a tubular shank (30). The shank has a truncated cone contour (32) on its extremity and at least one annular protuberant appendage (34) integrally formed with the shank (30) and extending from an outside surface of the distal end, for manipulation of intraocular tissue. The appendage (34) has a sloped surface (36) and extends either partially or completely around the periphery of the sleeve body (20). The appendage (34) may consist of single or multiple elements but in any case the appendage has a larger outside diameter than the shank.
