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.

First claim

1 - 9 . (canceled)

10 . A phacoemulsification system, comprising:
a cassette comprising positioning surfaces; and a console comprising: a cassette receiver configured to couple with the positioning surfaces of the cassette; and two potentiometers mounted within an area defined by the cassette receiver, wherein the potentiometers are each suitable for depression by a respective one of the positioning surfaces, and wherein an extent of the depressions is indicative of at least one of an alignment and an attitude of said cassette with respect to the cassette receiver.

11 . The phacoemulsification system of claim 10 , wherein the suitability for depression is provided by a spring loaded plunger shaft.

12 . The phacoemulsification system of claim 10 , wherein the console further comprises a comparator configured to compare, based on an electrical resistance reading, an extent of the depression of one of the potentiometers with that of another of the potentiometers to assess the attitude of the cassette.

13 . The phacoemulsification system of claim 12 , wherein said comparator is further configured to compare an extent of the depression of both of the two potentiometers to assess at a complete loading of the cassette into the cassette receiver.

14 . The phacoemulsification system of claim 10 , wherein the console further comprises a clamping mechanism suitable for clamping the cassette into the cassette receiver based on an assessment by said comparator of a minimum threshold for at least one of the alignment and the attitude.
