Abstract
A surgical system and cassette, the cassette having an identification method that is specific to the cassette. Suitable methods include bar coding or Radio Frequency Identification (“RFID”). Cassette information that may be encoded include features such as lot number and performance characteristics, such as pressure sensor calibration data, flow and pressure data and any other performance characteristics of the cassette captured during testing of the cassette at manufacture.
Claims22
A surgical system, comprising:
- a surgical console having a cassette receiving portion;
- a cassette sized and shaped to be received in the cassette receiving portion of the surgical console, the cassette comprising:
- a housing;
- a pressure sensor coupled to the housing;
- a bar code, located on the cassette;
- and
- pressure sensor calibration data, stored in the bar code, that includes unique information specific to operation of the pressure sensor coupled to the housing and determined for that unique pressure sensor by testing that unique pressure sensor on the cassette at manufacture;
- wherein the surgical console comprises an optical reader configured to read the pressure sensor calibration data when the cassette is in the cassette receiving portion of the surgical console;
- wherein software contained within the console is configured to automatically make appropriate adjustments in operating parameters of the console, in response to the read pressure sensor calibration data;
- and
- wherein said pressure sensor calibration data for multiple cassettes are determined by testing the pressure sensor on each cassette at manufacture.
A surgical cassette sized and shaped to be received in a cassette receiving portion of a surgical console, the cassette comprising:
- a housing;
- a pressure sensor coupled to the housing;
- a bar code, located on the cassette;
- and
- pressure sensor calibration data, stored in the bar code, that includes unique information specific to operation of the pressure sensor and determined for the pressure sensor by testing the pressure sensor on the cassette at manufacture;
- wherein the surgical console has an optical reader configured to read pressure sensor calibration data within the bar code when the cassette is in the cassette receiving portion of the surgical console;
- and
- wherein said pressure sensor calibration data for multiple cassettes are determined by testing the pressure sensor on each cassette at manufacture.
A method of manufacturing surgical cassettes, comprising:
- providing a housing for each cassette;
- coupling a separate pressure sensor to each of the cassette housings;
- determining pressure sensor calibration data individually for each separate pressure sensor by individually testing each separate pressure sensor during manufacturing;
- and
- coupling a bar code, with unique determined pressure sensor calibration data for a specific pressure sensor, to the cassette housing coupled to that specific pressure sensor;
- wherein the cassette is configured to be received in a surgical console that includes an optical reader configured to read the pressure sensor calibration data contained within the bar code when the cassette is received in the surgical console to automatically make appropriate adjustments in the operating parameters of the console according to the pressure sensor calibration data for that one unique pressure sensor.
