Abstract

A hand piece having an irrigation portion and an aspiration portion that are releasably coupled is disclosed. In an assembled configuration, the irrigation portion and the aspiration portion are coupled such that the hand piece may be manipulable by a user as a single unit. In a separated configuration, the irrigation portion and the aspiration portion may be utilized separate from each other. The irrigation portion and the aspiration portion may be freely moved between the assembled configuration and the separated configuration.

First claim

What is claimed is:

1. A surgical irrigation/aspiration system, comprising:
a handheld irrigation portion comprising a first outer surface and having an irrigation sleeve extending from a distal end of the handheld irrigation portion, the handheld irrigation portion configured to provide an irrigation fluid to a surgical site from a surgical console; and
a handheld aspiration portion comprising a second outer surface and having an aspiration tip extending from a distal end of the handheld aspiration portion, the handheld aspiration portion configured to provide aspiration from the surgical site;
wherein the handheld aspiration portion is configured to be removably coupled with the handheld irrigation portion such that, when coupled:
the aspiration tip extends through and is annularly surrounded by the irrigation sleeve and provides aspiration through a fluid outlet of the irrigation sleeve, and
the first outer surface of the handheld irrigation portion and the second outer surface of the handheld aspiration portion define a substantially continuous outer surface along a portion of the surgical irrigation/aspiration system; and

wherein the handheld irrigation portion is configured to provide the irrigation fluid to the surgical site and the handheld aspiration portion is configured to provide aspiration from the surgical site regardless of whether the handheld irrigation portion and handheld aspiration portion are coupled together.

2. The surgical irrigation/aspiration system of claim 1 , wherein the aspiration tip extends along a central axis of the irrigation sleeve when the handheld aspiration portion is coupled with the handheld irrigation portion.

3. The surgical irrigation/aspiration system of claim 1 , wherein a distal end of the aspiration tip extends beyond a distal end of the irrigation sleeve when the handheld aspiration portion is coupled with the handheld irrigation portion.

4. The surgical irrigation/aspiration system of claim 1 , wherein the handheld irrigation portion comprises a receptacle configured to receive the distal end of the handheld aspiration portion when the handheld aspiration portion is coupled with the handheld irrigation portion.

5. The surgical irrigation/aspiration system of claim 4 , wherein the receptacle forms a fluid-tight seal with the handheld aspiration portion when the handheld aspiration portion is coupled with the handheld irrigation portion.

6. The surgical irrigation/aspiration system of claim 4 , wherein the handheld irrigation portion and the handheld aspiration portion include interlocking elements for removably coupling the distal end of the handheld aspiration portion in the receptacle of the handheld irrigation portion.

7. The surgical irrigation/aspiration system of claim 6 , wherein the handheld irrigation portion interlocks with the handheld aspiration portion through a friction fit.

8. The surgical irrigation/aspiration system of claim 6 , wherein the handheld irrigation portion interlocks with the handheld aspiration portion through a snap fit.

9. The surgical irrigation/aspiration system of claim 4 , wherein the receptacle has a tapered portion configured to receive a cone-shaped portion of the handheld aspiration portion.

10. A surgical irrigation tool, comprising
a handheld irrigation portion comprising a first outer surface and configured to provide an irrigation fluid to a surgical site from a surgical console; and
an irrigation sleeve extending from a distal end of the handheld irrigation portion;
wherein the handheld irrigation portion is configured to be removably coupled with a handheld aspiration portion comprising a second outer surface and having an aspiration tip extending from a distal end of the handheld aspiration portion, such that, when the handheld irrigation portion and handheld aspiration portion are coupled:
the aspiration tip extends through and is annularly surrounded by the irrigation sleeve and provides aspiration from the surgical site through a fluid outlet of the irrigation sleeve, and
the first outer surface of the handheld irrigation portion and the second outer surface of the handheld aspiration portion define a substantially continuous outer surface along a portion of the surgical instrument; and

wherein the handheld irrigation portion is configured to provide the irrigation fluid to the surgical site regardless of whether the handheld irrigation portion and handheld aspiration portion are coupled together.

11. The surgical irrigation tool of claim 10 , wherein the handheld irrigation portion comprises a receptacle configured to receive the distal end of the handheld aspiration portion when the handheld aspiration portion is coupled with the handheld irrigation portion.

12. The surgical irrigation tool of claim 11 , wherein the receptacle forms a fluid-tight seal with the handheld aspiration portion when the handheld aspiration portion is coupled with the handheld irrigation portion.

13. The surgical irrigation tool of claim 11 , wherein the handheld irrigation portion and the handheld aspiration portion include interlocking elements for removably coupling the distal end of the handheld aspiration portion in the receptacle of the handheld irrigation portion.

14. The surgical irrigation tool of claim 13 , wherein the handheld irrigation portion interlocks with the handheld aspiration portion through a friction fit.

15. The surgical irrigation tool of claim 13 , wherein the handheld irrigation portion interlocks with the handheld aspiration portion through a snap fit.

16. The surgical irrigation tool of claim 11 wherein the receptacle has a tapered portion configured to receive a cone-shaped portion of the handheld aspiration portion.

17. A surgical aspiration tool, comprising:
a handheld aspiration portion comprising a first outer surface and configured to provide aspiration from a surgical site; and
an aspiration tip extending from a distal end of the handheld aspiration portion;
wherein the handheld aspiration portion is configured to be removably coupled with a handheld irrigation portion comprising a second outer surface and having an irrigation sleeve extending from a distal end of the handheld irrigation portion, the handheld irrigation portion configured to provide an irrigation fluid to the surgical site from a surgical console, such that, when the handheld aspiration portion and handheld irrigation portion are coupled:
the aspiration tip extends through and is annularly surrounded by the irrigation sleeve and provides aspiration from the surgical site through a fluid outlet of the irrigation sleeve, and
the first outer surface of the handheld aspiration portion and the second outer surface of the handheld irrigation portion define a substantially continuous outer surface along a portion of the surgical instrument; and

wherein the handheld aspiration portion is configured to provide the aspiration from the surgical site regardless of whether the handheld irrigation portion and handheld aspiration portion are coupled together.

18. The surgical aspiration tool of claim 17 , wherein the aspiration tip extends along a central axis of the irrigation sleeve when the handheld aspiration portion is coupled with the handheld irrigation portion.

19. The surgical aspiration tool of claim 17 , wherein a distal end of the aspiration tip extends beyond a distal end of the irrigation sleeve when the handheld aspiration portion is coupled with the handheld irrigation portion.
