Probe tip and infusion sleeve for use in ophthalmological surgery

A phacoemulsification probe tip, comprising:

• a body having a first diameter with a central axis running therethrough having a first end and a second distal end with a second axis running therethrough, wherein the second axis is at a predetermined angle to the central axis, wherein the body further defines a channel therein for aspirating material therethrough from a surgical region, the body including a straight portion connected to the first end and a curved portion connecting the straight portion to the second distal end, the body further including an annular protrusion having a second diameter larger than the first diameter, the annular protrusion surrounding the body and axially displaced from the second distal end along the second axis such that a portion of the probe tip extends from the second end to the annular protrusion;
• and
• a fluid sleeve which surrounds at least a portion of the body and defines a channel between the fluid sleeve and the body for injecting a fluid into the surgical region, an end of the fluid sleeve securely fitting over the annular protrusion to substantially seal the end of the fluid sleeve.

A phacoemulsification probe tip, comprising:

• a body defining a channel therein for aspirating material therethrough from a surgical region along a first vector from a first end, the body further including an annular protrusion having a second diameter larger than a first diameter of the body, the annular protrusion surrounding the body and axially displaced from the first end such that a portion of the probe tip extends from the second end to the annular protrusion;
• and
• a fluid sleeve which surrounds at least a portion of the body and defines a channel between the fluid sleeve and the body for injecting a fluid into the surgical region along a second vector.
