Critical alignment of fluidics cassettes
View Patent ↗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.
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.
