Title
(EN) DEVICE AND METHOD FOR FRACTURING AND REMOVING OCULAR LENSES
(FR) DISPOSITIF ET PROCÉDÉ DE FRACTURATION ET D'ÉLIMINATION DE LENTILLES OCULAIRES
Abstract
(EN)
The present invention relates to a device (10) for fracturing and removing ocular lenses. The device mainly comprises a rotational screw drill (1), a sleeve (2) and a hydraulic suction system (9). The rotational screw drill (1) has reversed conical propellers (1f) which help to grind the particles. The rotational screw drill (1) is housed in a sleeve (2), which comprises a rigid cylinder (2b) and a suction cup (2a). The suction cup (2a) has a bell or funnel shape with an elliptical cross-section. Finally, the hydraulic suction system (9) is key for the present invention performance. Also, the invention relates to a method comprising the steps of breaking, splitting the cataract or lens (100) tissue and simultaneously or subsequently grinding the particles inside the sleeve (2) by means of the rotational screw drill (1) and the sleeve (2), and finally removing them from the medium via the sleeve (2) by means of a hydraulic suction system (9).

La présente invention concerne un dispositif (10) de fracturation et d'élimination de lentilles oculaires. Le dispositif comprend principalement une perceuse à vis rotative (1), un manchon (2) et un système d'aspiration hydraulique (9). La perceuse à vis rotative (1) a des hélices coniques inversées (1f) qui aident à broyer les particules. La perceuse à vis rotative (1) est logée dans un manchon (2), qui comprend un cylindre rigide (2b) et une ventouse (2a). La ventouse (2a) présente une forme en cloche ou en entonnoir ayant une section transversale elliptique. Enfin, le système d'aspiration hydraulique (9) est essentiel aux performances de la présente invention. L'invention concerne également un procédé comprenant les étapes de rupture, de division du tissu de cataracte ou de lentille (100) et de broyage simultané ou ultérieur des particules à l'intérieur du manchon (2) au moyen de la perceuse à vis rotative (1) et du manchon (2), et enfin de retrait de celles-ci de l'instrument par l'intermédiaire du manchon (2) au moyen d'un système d'aspiration hydraulique (9).
