Abstract
A phacoemulsification probe includes a first portion for interconnecting the probe with a phacoemulsification machine. A probe tip has a first end connected with the first portion and a second end curved up to a predetermined angle. The probe tip defines a channel therein for aspirating material through the probe tip from a surgical region.
Claims20
A phacoemulsification probe tip, comprising:
- a body having a first end and a second end, the body further having an outer wall defining only a single channel therein for aspirating material therethrough from a surgical region in an eye at the second end, the body including a straight portion connected to the first end and a curved portion connecting the straight portion to the second end, the body further defining an annular protrusion surrounding only the single channel defined within the body and axially displaced from the second end such that a portion of the curved portion of the probe tip extends from the second end to the annular protrusion;
- and
- wherein the probe tip is configured to vibrate at ultrasonic frequencies.
A phacoemulsification probe tip, comprising:
- a body defining a channel therein for aspirating material therethrough from a surgical region, the body including a straight portion connected to a first end and a curved portion connecting the straight portion to a second end, the body further defining 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;
- 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 having an outer wall defining only a single channel therein for aspirating material therethrough from a surgical region in an eye along a first vector from a first end, the body including a straight portion connected to a second end and a curved portion connecting the straight portion to the 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 only the single channel defined within the body and axially displaced from the first end such that a portion of the curved portion of the probe tip extends from the first end to the annular protrusion.
