Transformer irrigation/aspiration device
First Claim
1. A cannula device, comprising:
- an irrigation handpiece portion comprising a first aspiration tip configured to provide aspiration and an irrigation fluid outlet configured to provide an irrigation fluid;
an aspiration handpiece portion comprising a second aspiration tip configured to provide aspiration, wherein the second aspiration tip extends from a distal end of the aspiration handpiece portion;
wherein the cannula device is transformable between;
a coaxial mode in which the aspiration handpiece portion is coupled to the irrigation handpiece portion such that fluid is aspirated through the first aspiration tip and then the second aspiration tip in series and the irrigation fluid is provided through the irrigation fluid outlet, anda bimanual mode in which the aspiration handpiece portion is separated from the irrigation handpiece portion to provide aspiration through the second aspiration tip while the irrigation handpiece portion continues to provide the irrigation fluid through the irrigation fluid outlet but not aspiration through the first aspiration tip.

Abstract
In various embodiments, a cannula device includes an irrigation handpiece portion (with a first aspiration tip for aspiration and an irrigation fluid outlet for irrigation) and an aspiration handpiece portion (configured to aspirate fluid into a second aspiration tip that extends from a distal end of the aspiration handpiece portion). The cannula device is transformable between: (a) a coaxial mode in which the aspiration handpiece portion is coupled to the irrigation handpiece portion such that fluid is aspirated through the first aspiration tip and then the second aspiration tip in series and irrigation fluid is provided through the irrigation fluid outlet, and (b) a bimanual mode in which the aspiration handpiece portion is separated from the irrigation handpiece portion to provide aspiration through the second aspiration tip while the irrigation handpiece portion continues to provide irrigation fluid through the irrigation fluid outlet.

10. A method, comprising:
-
inserting an aspiration tip of an aspiration handpiece portion into a seal in an irrigation handpiece portion to place the aspiration tip of the aspiration handpiece portion in fluid communication with an aspiration pathway of the irrigation handpiece portion such that fluid entering an aspiration tip on the irrigation handpiece portion passes through an interior of the irrigation handpiece portion, into the aspiration tip of the aspiration handpiece portion, and then out of the aspiration handpiece portion; coupling the aspiration handpiece portion to the irrigation handpiece portion to form a coaxial handpiece; providing aspiration through the aspiration tip on the irrigation handpiece portion and irrigation fluid through an irrigation fluid outlet on the irrigation handpiece portion; decoupling the aspiration handpiece portion from the irrigation handpiece portion; withdrawing the aspiration tip of the aspiration handpiece portion from the seal in the irrigation handpiece portion to form two separate handpieces; and providing the irrigation fluid through the irrigation fluid outlet on the irrigation handpiece portion and aspiration through the aspiration tip on the aspiration handpiece portion. - View Dependent Claims (11, 12, 13)
