Device, system and method for assessing attitude and alignment of a surgical cassette

摘要

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.

主权项

1. A cassette attitude assessment system, comprising:
a cassette receiver configured to couple with a cassette having positioning surfaces; two detectors mounted diagonally within an area defined by said cassette receiver, each of said detectors providing a depressable rod in the area defined by the cassette receiver, wherein each of the depressable rods is configured to be depressed by one of the positioning surfaces of the cassette; and a comparator configured to compare, based on an electrical resistance reading, an extent of the depression of one of the depressable rods with that of another of the depressable rods to assess an attitude of the cassette.
