17. The assembly of claim 16, wherein the irrigation tubing is configured for connection to at least two fluid sources by way of a dual pathway irrigation tubing that leads to a common tubing junction located upstream of the cassette.

18. The assembly of claim 16, further comprising at least one pinch clamp configured for preventing fluid flow along the suction tubing or irrigation tubing.

19. The assembly of claim 16, wherein the cassette is configured for connection with a reusable pump system such that during use, fluid from the fluid source flows through the cassette, into the pump system, out of the pump system, through the cassette again, and to the handpiece via the irrigation tubing.

20. The assembly of claim 16, wherein the pump system is powered by an AC power source.

21. The assembly of claim 16, wherein the cassette includes electrical contacts configured to establish electrical connection to corresponding contacts in the reusable pump system.

22. The assembly of claim 21, wherein the electrical contacts of the cassette extend to electrical wiring that leads to the handpiece, and wherein the handpiece includes an irrigation control button including at least one conductive contact such that actuation of the irrigation button closes an electric circuit, thereby providing power to the pump system.

23. The assembly of claim 21, wherein the electrical wiring extending from the cassette runs along an exterior surface of the irrigation tubing between the cassette and the handpiece.

24. The assembly of claim 16, wherein the cassette includes a collar configured for engagement with an aperture of the reusable pump system upon rotation of the collar within the aperture.
