ABSTRACT:
A surgical suction cassette for use with a microsurgical apparatus having a surgical handpiece connected by tubing with a control cabinet contains a tank to receive aspirated material from the microsurgical site, fluid connections for the tubes providing suction, pressure and irrigation fluid to the handpiece, fluid connections for connecting sources of pressure, vacuum and vent within the cabinet, fluid connection for an external source of irrigation fluid, and internal tubing providing connections between the connections to the handpiece and the connections to the cabinet. Solenoid actuated occluders in the cabinet compress the tubing in the cassette to turn the various fluid streams on and off. The cassette is provided with a drain for automatically removing the contents without changing the cassette. A latch hook, centrally located between the fluid connections to the cabinet holds the cassette in the cabinet when in use.
