A surgical cassette (150) is provided which is adapted for insertion into a cassette receiver (125) in a surgical console (100) and to be held in place by at least one clamp (144,184) in the cassette receiver, the cassette comprising compliant clamping zones (160,190; 165,195) configured to deform to conform to any non-uniform load profile applied to the cassette. The clamping portion(s) (190,195) can include ribs (240) that are sized and made of a suitable material such that the ribs will deflect predictably in an elastic region and flow plastically when the material yield point is exceeded. The use of ribs creates discrete small load areas that will deflect and distort predictably and non-catastrophically at high loads. This allows for the absorption of accumulated tolerances between the clamping mechanism (142,144; 182,184) and the cassette (e.g. non-parallelism between the clamping mechanism and the cassette while still providing a distributed load on the cassette. |
