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.

Claims

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;

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, 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 creates a cyclonic movement within the surgical region.

2. The aspiration probe tip of claim 1, further including an aspiration controller for selectively controlling aspiration of material from the surgical region into the first channel.

3. The aspiration probe tip of claim 1, further including an irrigation controller for selectively controlling injection of the fluid through the aperture from the second channel into the surgical region.

4. The aspiration probe tip of claim 8, wherein the probe tip is configured to vibrate at ultrasonic frequencies.

5. The aspiration probe tip of claim 1, further including a sonic controller for selectively controlling the vibrations of the probe tip at the ultrasonic frequencies

6. The aspiration probe tip of claim 1, wherein the probe tip circularly rotates about an axis running through the first end of the probe tip.

7. The aspiration probe tip of claim 1, 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

8. The aspiration probe tip of claim 7, wherein an end of the fluid sleeve securely fits over the annular protrusion to substantially seal the end of the fluid sleeve.

9. 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, 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, an end of the fluid sleeve securely fitting over the annular protrusion 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 creates a cyclonic movement within the surgical region.

10. The aspiration probe tip of claim 9, further including an aspiration controller for selectively controlling aspiration of material from the surgical region into the first channel.

11. The aspiration probe tip of claim 9, further including an irrigation controller for selectively controlling injection of the fluid through the aperture from the second channel into the surgical region.

12. The aspiration probe tip of claim 11, wherein the probe tip is configured to vibrate at ultrasonic frequencies.

13. The aspiration probe tip of claim 9, further including a sonic controller for selectively controlling the vibrations of the probe tip at the ultrasonic frequencies

14. The aspiration probe tip of claim 9, wherein the probe tip circularly rotates about an axis running through the first end of the probe tip.

15. 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;

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, 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;

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 creates a cyclonic movement within the surgical region;

an aspiration controller for selectively controlling aspiration of material from the surgical region into the first channel; and

an irrigation controller for selectively controlling injection of the fluid through the aperture from the second channel into the surgical region.

16. The aspiration probe tip of claim 15, wherein the probe tip is configured to vibrate at ultrasonic frequencies.

17. The aspiration probe tip of claim 16, further including a sonic controller for selectively controlling the vibrations of the probe tip at the ultrasonic frequencies

18. The aspiration probe tip of claim 15, wherein the probe tip circularly rotates about an axis running through the first end of the probe tip.

19. The aspiration probe tip of claim 15, 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

20. The aspiration probe tip of claim 19, wherein an end of the fluid sleeve securely fits over the annular protrusion to substantially seal the end of the fluid sleeve.
