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

We claim:

1. An Irrigation/Aspiration (I/A) hand piece comprising:
an irrigation portion comprising a hand graspable handpiece body with an outer surface gripping portion; and
an aspiration portion comprising a hand graspable handpiece body with an outer surface gripping portion,
one of the body of the irrigation portion or body of the aspiration portion comprising an integral, longitudinally extending receptacle into which at least a portion of the other of the irrigation portion or aspiration portion is removably received in a manner forming a single graspable outer surface portion for both the irrigation portion and aspiration portion that is graspable by one hand for both irrigation and aspiration of a surgical site.

2. The I/A hand piece of claim 1 , wherein one of the irrigation portion or the aspiration portion comprises a recess within the hand graspable handpiece body and wherein the hand graspable handpiece body of the other of the irrigation portion or the aspiration portion includes a profile configured to be releasably received into the recess.

3. The I/A hand piece of claim 2 , wherein the recess extends longitudinally along the hand graspable handpiece body.

4. The I/A hand piece of claim 1 , wherein the receptacle and the portion of the other of the irrigation portion or the aspiration portion received within the receptacle form a fluid-tight seal.

5. The hand piece of claim 1 , wherein the hand piece is selectively configurable between an assembled configuration in which the irrigation portion and the aspiration portion are coupled together such that the at least a portion of irrigation portion or the aspiration portion is received within the receptacle of the other of the irrigation portion or the aspiration portion and a separated configuration in which the irrigation portion and the aspiration portion are decoupled from each other.

6. The I/A hand piece of claim 5 further comprising an irrigation sleeve.

7. The I/A hand piece of claim 6 , wherein the aspiration portion comprises the receptacle, and
wherein at least a portion of the irrigation portion is received within the receptacle in the assembled configuration.

8. The I/A hand piece of claim 7 , wherein the irrigation sleeve is coupled to a distal end of the aspiration portion,
wherein the aspiration portion comprises an aspiration needle, the aspiration needle extending through an opening formed in the irrigation sleeve,
wherein the irrigation portion comprises a passage, and
wherein the passage of the irrigation portion communicates with an interior of the irrigation sleeve.

9. The I/A hand piece of claim 7 , wherein a proximal portion of the irrigation sleeve is releasably coupled to a distal end of the aspiration portion.

10. The hand piece of claim 7 , wherein the irrigation portion comprises a longitudinally-extending recess and wherein the aspiration portion comprises a cross-sectional shape configured to be releasably received into the longitudinally-extending recess.

11. The I/A hand piece of claim 6 , wherein the irrigation portion comprises the receptacle, and
wherein at least a portion of the aspiration portion is received within the receptacle in the assembled configuration.

12. The I/A hand piece of claim 11 , wherein the irrigation portion comprises an annular outlet formed at a distal end thereof and wherein the receptacle of the irrigation portion defines a central opening disposed in a central region circumscribed by the annular opening.

13. The hand piece of claim 12 , wherein the aspiration portion is received in the receptacle, a distal portion of the aspiration portion extending through the central opening of the irrigation portion.

14. The I/A hand piece of claim 13 , wherein the aspiration portion comprises an aspiration needle, wherein the irrigation sleeve is coupled to a distal end of the irrigation portion, and wherein the aspiration needle extends through an opening formed in the irrigation sleeve.

15. The I/A hand piece of claim 11 , wherein the irrigation portion comprises a longitudinally-extending recess and wherein the aspiration portion comprises a cross-sectional shape configured to be releasably received into the longitudinally-extending recess.

16. An Irrigation/Aspiration (I/A) hand piece comprising:
an irrigation portion comprising:
an inlet;
an outlet:
a passage extending between the inlet and the outlet; and
a hand graspable handpiece body with an outer surface gripping portion:

an aspiration portion comprising:
an inlet;
an outlet;
a passage extending between the inlet and the outlet;
a receptacle; and
a hand graspable handpiece body with an outer surface gripping portion,

the I/A hand piece selectively configurable between an assembled configuration in which a portion of the irrigation portion is releasably received into the receptacle of the aspiration portion in a manner forming a single graspable outer surface portion for both the irrigation portion and aspiration portion that is graspable by one hand for both irrigation and aspiration of a surgical site and a separated configuration in which the irrigation portion and the aspiration portion are decoupled from each other.

17. The I/A hand piece of claim 16 , wherein an inner surface of the receptacle and an outer surface of the irrigation portion form a fluid-tight seal around the irrigation portion.

18. The I/A hand piece of claim 16 further comprising an irrigation sleeve releasably coupled to a distal end of the aspiration portion.

19. The I/A hand piece of claim 18 , wherein the irrigation portion comprises an irrigation needle, an outlet of the irrigation needle in communication with an interior of the irrigation sleeve, wherein the aspiration portion comprises an aspiration needle, the aspiration needle extending through an opening formed in the irrigation sleeve.

20. The I/A hand piece of claim 16 , wherein the irrigation portion comprises a longitudinally-extending recess and wherein the aspiration portion comprises a cross-sectional shape configured to be releasably received into the longitudinally-extending recess.

21. An Irrigation/Aspiration (I/A) hand piece comprising:
an irrigation portion comprising:
an irrigation passage; and
a first outer surface around the irrigation passage, the outer surface comprising a hand graspable handpiece body with an outer surface gripping portion; and

an aspiration portion comprising:
an aspiration passage; and
an outer surface around the aspiration passage, the outer surface comprising a hand graspable handpiece body with an outer surface gripping portion,
one of the irrigation portion or the aspiration portion comprising a receptacle into which at least a portion of the other of the irrigation portion or aspiration portion is removably received such that the first outer surface and second outer surface are aligned in series along a longitudinal axis to form a single graspable portion.

22. The I/A hand piece of claim 21 , wherein the irrigation portion is graspable for independent use by a user.

23. The I/A hand piece of claim 21 , wherein the aspiration portion is graspable for independent use by a user.
