Abstract

A surgical cassette arrangement is provided. The arrangement includes a flow selector valve configured to operate with a handpiece to selectively irrigate and aspirate fluid with respect to an ocular region. The flow selector valve includes at least three ports, with one port fluidly connectable to the handpiece. The arrangement further includes a reservoir fluidly connected to a second port of the flow selector valve via a first flow segment and configured to receive fluid from the flow selector valve, and a collector fluidly connected to a third port of the flow selector valve via a second flow segment and configured to receive fluid from the flow selector valve and from the reservoir. The flow selector valve selectively controls irrigation and aspiration flow to the handpiece and ocular region.

10. The surgical cassette arrangement of claim 1, wherein said surgical cassette arrangement is configured to operate in connection with an ocular surgical procedure.

11. The surgical cassette arrangement of claim 1, wherein said flow selector valve is controlled by an instrument host configured to select operational parameters based on data received.

12. The surgical cassette arrangement of claim 1, wherein the fluid selector valve is further configured to selectively receive fluid from the first fluid pathway or the second fluid pathway and distribute fluid to an eye via the handpiece.

13. The surgical cassette arrangement of claim 1, further comprising a fluid source, the fluid source configured to distribute fluid to the handpiece and the flow selector valve, and wherein the flow selector valve comprises a third port fluidly connectable to the fluid source.

14. A method for selectively venting and aspirating fluid to and from a handpiece employed in an ocular surgical procedure, comprising:

providing a first pumping operation and a second pumping operation; and

selecting operation between the first pumping operation and the second pumping operation using a flow selector valve;

wherein the first pumping operation controls fluid flow to and from an eye using a first pump fluidly connecting the flow selector valve to a first fluid pathway via a first port in the flow selector valve and the second pumping operation controls fluid flow to and from the eye using a second pump fluidly connected to the flow selector valve via a second fluid pathway connected to a second port in the flow selector valve.

15. The method of claim 14, wherein the first pumping operation and/or the second pumping operation may be selectively reversed.

16. The method of claim 14, further comprising enabling further pumping from the reservoir to a collector.

17. The method of claim 14, wherein the first pumping operation comprises a pump drawing fluid through the flow selector valve and passing the fluid to a collector.
