Surgical cassette apparatus

A surgical cassette arrangement coupled with a handpiece, the surgical cassette arrangement comprising:

• a surgical cassette, wherein the surgical cassette comprises:
• a flow selector valve configured to operate with the handpiece to selectively irrigate and aspirate fluid with respect to an ocular region, the flow selector valve comprising a first port, a second port, and a third port, wherein the second and third port are each configured to both receive and transmit fluid, with the first port fluidly connectable to the handpiece;
• and
• a reservoir fluidly connected to the second port of the selector valve via a first flow segment within the surgical cassette and configured to receive fluid from the flow selector valve;
• and
• a collector fluidly connected to the 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;
• wherein the flow selector valve is configured to selectively control irrigation and aspiration flow to and from the handpiece and ocular region.

A surgical cassette arrangement fluidly connected with a handpiece, the surgical cassette arrangement comprising:

• a surgical cassette, wherein the surgical cassette comprises:
• a reservoir configured to hold fluid;
• and
• a flow selector valve arrangement fluidly connected to the handpiece and having a first port and a second port that are each configured to both receive and transmit fluid;
• and
• a collector configured to collect fluid;
• wherein the first port is fluidly connected with the reservoir through a first fluid pathway within the surgical cassette and the second port is fluidly connected with the collector through a second fluid pathway;
• wherein the collector is configured to collect fluid received from the flow selector valve arrangement via the first fluid pathway and from the reservoir via a third fluid pathway.
