Abstract

A system and method of receiving a cassette to a console of a phacoemulsification system. The system and method may include receiving the cassette in close proximity to a cassette receptacle comprising a receiving surface, sensing variations in at least two variable resistances mounted respectively diagonally about the receiving surface, and comparing the variations as between the at least two variable resistances to assess an attitude of the cassette. The system and method may optionally include clamping the cassette responsively to the comparing step.

Claims

1-14. -14. (canceled)

15. A method of receiving a cassette to a console of a phacoemulsification system, comprising:

receiving the cassette into immediate proximity with a cassette receiver comprising a receiving surface;

sensing variations in detectors mounted respectively diagonally about the receiving surface, wherein the variations are indicative of pressure asserted by the received cassette on the receiving surface; and

comparing the variations as between the detectors to assess an attitude of the cassette.

16. The method of claim 15, wherein the variations comprise linear depressions of the detectors.

17. The method of claim 15, wherein said comparing the variations further comprises comparing the variations to known linear depressions to assess an alignment of the cassette.

18. The method of claim 15, wherein said comparing the variations further comprises comparing the variations to known linear depressions to assess a complete loading of the cassette.

19. The method of claim 15, further comprising clamping the cassette responsively to said comparing.

20. The method of claim 19, wherein said clamping comprises dynamically clamping responsively to said comparing.

21. The method of claim 19, wherein said clamping comprises dynamically unclamping responsively to said comparing.
