Abstract:

A surgical console has a receptacle for receiving a surgical fluidics cassette. The receptacle has a light source that transmits light to light pipes in the surgical fluidics cassette. The light pipes transmit light to a light transmissive optical interface surrounded by an opaque frame in the surgical fluidics cassette. The opaque frame is located at a fluid level detection system in the cassette. The system illuminates fluidic connectors on the surgical fluidics cassette without interfering with the fluid level detection system of a surgical console.
