Abstract

Devices, systems, and methods interface a cassette with an eye treatment system console to provide coupling between the console and an eye treatment probe. The console may receive the cassette using a driven axial translation linkage that inhibits rotation of the cassette. The cassette may facilitate accurately positioning of a pressure sensor relative to a the console by allowing sliding movement between the sensor and a cassette body. Multiple peristaltic drives may be mounted to the console so that their rotors rotate about a common axis. An integrated mount structure may support and/or position components of the console which will interface with cassette, and an axially compressible vacuum connector of the console seal to a tapered vacuum coupler of the cassette.

Claims

1. A method for mounting an eye treatment cassette to an eye treatment console, the method comprising:

displacing channels by engaging positioning surfaces of the cassette against receptacle surfaces of the console;

actuating a microswitch to activate a controller via the cassette;

energizing an actuator by the controller; and

translating an axial translation linkage of the console with the energized actuator so as to axially translate the cassette to a mounted position while the receptacle surfaces inhibit rotation of the cassette.

2. The method of claim 1, wherein the cassette is brought into engagement with the receptacle surfaces while the cassette is supported by a single hand, and further comprising moving a first receptacle surface relative to a second receptacle surface during translation of the cassette so as to more accurately align a plurality of interfaces of the cassette with a corresponding plurality of interfaces of the console.

3. The method of claim 1, wherein the microswitch is exposed along the receptacle surfaces.

4. The method of claim 1, wherein the microswitch is coupled to the axial translation linkage.
