Probe tip and infusion sleeve for use in ophthalmological surgery
First Claim
1. An aspiration probe tip for use in surgical procedures, comprising:
- a body defining a first channel therein for aspirating material therethrough from a surgical region along a first vector, the body including a straight portion connected to a first end and a curved portion connecting the straight portion to a second end, wherein the body further defines an annular protrusion surrounding the body and axially displaced from the second end such that a portion of the probe tip extends from the second end to the annular protrusion;
a fluid sleeve which surrounds at least a portion of the body and defines a second channel between the fluid sleeve and the body for injecting a fluid into the surgical region along a second vector in a non-competitive direction to the first vector, an end of the fluid sleeve securely fitting over the body to substantially seal the end of the fluid sleeve, the fluid sleeve further defining an aperture for injecting fluid along the second vector from the second channel into the surgical region; and
wherein a combination of the aspiration of the material into the first channel from the surgical region along the first vector and injection of fluid into the surgical region from the second channel along the second vector in the non-competitive direction to the first vector creates a cyclonic movement within the surgical region.

Abstract
An aspiration probe tip for use in surgical procedures includes a body defining a first channel therein for aspirating material therethrough from a surgical region along a first vector. The body includes a straight portion connected to a first end and a curved portion connecting the straight portion to a second end. A fluid sleeve surrounds at least a portion of the body and defines a second channel between the fluid sleeve and the body for injecting a fluid into the surgical region along a second vector. An end of the fluid sleeve securely fits over the body to substantially seal the end of the fluid sleeve. The fluid sleeve further defines an aperture for injecting fluid along the second vector from the second channel into the surgical region. A combination of the aspiration of the material into the first channel from the surgical region along the first vector and injection of fluid into the surgical region from the second channel creates a cyclonic movement within the surgical region.
