First Claim
1. A opthalmic microsurgical system comprising:
- a console having a source of vacuum and control means associated therewith;
a cassette assembly means adapted for releasable securement to said console;
surgical apparatus adapted for remote connection to said cassette assembly and to be disposed in the vicinity of the surgery situs and including an inlet means for application of vacuum;
first conduit means coupled to said inlet means and said vacuum source for carrying material away from said surgery situs;
said control means including first means cooperating with said cassette assembly for selectively isolating said vacuum source from said first conduit means;
said cassette assembly having a body portion;
a collection vessel associated with said body portion, first port means for communication with said first conduit means, second port means for communication with said vacuum source;
said cassette assembly also including first flexible occludable means on the cassette coupled between said first flexible and second port means and arranged for cooperation with said first means when said cassette assembly is secured to said console to isolate said vacuum source from said first port means in response to a first signal;
said collection vessel adapted to be coupled to said first conduit means to collect material extracted from said surgery situs.

Abstract
A microsurgery system comprising an instrument including a source of vacuum and control means, a remotely connected handpiece adapted to be disposed in the vicinity of the situs of the surgery and including an inlet and suction conduit means coupled to the inlet and to the vacuum source for carrying material away from the surgery situs. The system also includes a cassette assembly arranged for releasable securement to the instrument. The control means of the instrument includes an interrupter bar which cooperates with the cassette assembly for selectively isolating the vacuum source from the suction conduit means. The cassette assembly comprises a body portion, a collection vessel, a first port communicating with the suction conduit and a second port communicating with the vacuum source. Occludable conduit means are coupled between the first and second ports and are arranged to be engaged by the interrupter bar in response to a first signal to isolate the vacuum source from the suction means. The collection vessel is coupled to the suction conduit to collect the material extracted from the surgery situs. The cassette also includes similar means for enabling or disabling the flow of infusion liquid through an infusion line to the surgery situs. A hydrophobic filter and a check valve are also located within the cassette assembly.
