ABSTRACT:
A cassette is structurally adapted to receive at least a portion of an irrigation manifold and an aspiration manifold, so that when the cassette is firmly secured to a cassette mechanism on an emulsifier/aspirator unit: (1) the flow to irrigation solution through the irrigation manifold is regulated; (2) the flow of aspirated fluid and tissue from the surgical site is regulated; (3) the vacuum control system (VCS) within the unit is applied to the aspiration manifold. The cassette defines, at its leading edge, an irrigation opening, an aspiration pump opening, and a vacuum control system opening. The cassette housing defines an irrigation boss having a flat leading edge surface in register with the irrigation opening, while an aspiration boss is located in register with the aspiration pump opening. A cassette mechanism is located on the emulsifier/aspirator unit and is structurally adapted to receive the cassette to complete the fluidic connection upon insertion of the cassette.
