摘要:
Embodiments of the present invention provide a surgical cassette with compliant clamping zones to provide more uniform loading. According to one embodiment of the present invention, a surgical cassette includes a clamping portion that is configured to deform to conform to non-uniform load profile applied to the cassette. The clamping portion can include ribs that are sized and made of a suitable material such that the ribs will deflect predictably in the 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 and cassette (e.g., the non-parallelism between the clamping mechanism and cassette) while still providing a distributed load on the cassette.
