Abstract[English]
Some embodiments provide a surgical cassette designed for use in ophthalmic surgical procedures, which features a multiple chamber pump elastomer to seal multiple chambers within the device. The elastomer is comprised of a silicone rubber component that incorporates a plurality of grooves on its top face and seal beads on its lower portion. The grooves enable lateral deformation of the silicone rubber under compression, improving the seal of the multiple chambers and reducing or eliminating leak paths, thus enhancing the device's performance. The seal beads, strategically placed on the lower portion of the silicone rubber component, prevent separation and lifting of the pump elastomer at the corners by conforming to the geometry of the corners.[French]
Certains modes de réalisation concernent une cassette chirurgicale conçue pour être utilisée dans des procédures chirurgicales ophtalmiques, qui comprend un élastomère de pompe à chambres multiples pour sceller de multiples chambres à l'intérieur du dispositif. L'élastomère est constitué d'un composant de caoutchouc de silicone qui incorpore une pluralité de rainures sur sa face supérieure et des bourrelets d'étanchéité sur sa partie inférieure. Les rainures permettent une déformation latérale du caoutchouc de silicone sous compression, ce qui améliore l'étanchéité des multiples chambres et réduit ou élimine les trajets de fuite, ce qui permet d'améliorer les performances du dispositif. Les bourrelets d'étanchéité, placés stratégiquement sur la partie inférieure du composant de caoutchouc de silicone, empêchent la séparation et le levage de l'élastomère de pompe au niveau des coins en se conformant à la géométrie des coins.
