Surgical cassette with bubble separating structure

1. A surgical cassette, comprising:

an aspiration chamber, comprising:

a first entry for fluidly coupling to a surgical device;

a second entry for fluidly coupling to a source of vacuum in a surgical console for aspirating liquid infusion fluid from said surgical device; and

a bubble separating structure disposed within said aspiration chamber that divides said aspiration chamber into a first section and a second section, said bubble separating structure having:

a first support surface for mating with a first internal wall of said aspiration chamber;

a second support surface for mating with a second internal wall of said aspiration chamber; and

a dividing surface disposed between said first support surface and said second support surface;

wherein said dividing surface has a first opening that allows passage of liquid but prevents passage of air bubbles from said first section to said second section, said first support surface has a second opening that allows liquid from said second section to return to said first section, and said second section collects fluid for measuring a fluid level in said aspiration chamber.

2. The surgical cassette of claim 1 wherein said first entry is disposed proximate a bottom of said aspiration chamber and said second entry is disposed proximate a top of said aspiration chamber.

3. The surgical cassette of claim 2 wherein said first opening is disposed proximate a bottom of said dividing surface.

4. The surgical cassette of claim 3 wherein said second opening is disposed proximate a top of said first support surface.

5. The surgical cassette of claim 4 wherein said first opening and said second opening function to keep a fluid level in said first section equal to a fluid level in said second section.

6. The surgical cassette of claim 1 wherein said bubble separating structure is opaque.
