Abstract

L'invention concerne une cartouche de lentille intraoculaire permettant d'injecter une lentille intraoculaire dans le globe oculaire, ainsi qu'un mécanisme d'injection l'utilisant. Une surface du corps de la cartouche possédant une forme cylindrique est découpée dans le sens de la longueur afin de former une paire saillante de parties ailettes sur les deux côtés de celle-ci. Une partie pliante est disposée sur une surface opposée de chacune des parties ailettes afin que le corps de la cartouche puisse tourner. Un trou de guidage de cartouche pour fixer la lentille intraoculaire et d'insérer en douceur la lentille intraoculaire, est formé en retrait dans une surface interne du corps de cartouche connectant la partie ailette à la partie pliante. Une partie d'insertion de la cartouche de forme conique est disposée sur un côté du corps de la cartouche afin d'insérer la lentille intraoculaire injectée dans un espace de réception interne. La présente invention permet de simplifier la structure d'une cartouche sur laquelle une lentille intraoculaire est montée, d'un cylindre pour insérer la lentille intraoculaire monté dans l'espace de réception de la cartouche et d'un plongeur, afin d'insérer facilement la lentille intraoculaire dans le globe oculaire d'un patient et de réduire le temps de l'opération.
