SURGICAL CASSETTE WITH COMPLIANT CLAMPING ZONE |
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 a nd flow plastically when the material yield point is exceeded. The use of ribs creat es 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. |
