Abstract
L'invention concerne un système (300) et un procédé permettant de réduire et d'enlever le cristallin de l'oeil d'un mammifère. Ledit système (300) comporte un dispositif à sonde rotatif (302) de réduction du cristallin présentant une configuration rectiligne ou incurvée. Ledit dispositif à sonde (302) comprend une gaine extérieure (320) tubulaire dans laquelle s'étend un arbre d'entraînement (316) rotatif. Une tête rotative (318) de réduction de cristallin est placée à l'extrémité distale de l'arbre d'entraînement (316). Cette tête (318) est configurée et construite de façon à aspirer un flux de fluide et de matière constituant le cristallin entrant en contact avec elle ce qui facilite la réduction complète du cristallin sans qu'il soit nécessaire de faire exécuter un mouvement axial (c'est-à-dire longitudinal) important à la sonde à l'intérieur de la capsule du cristallin. La partie distale de la gaine tubulaire (320) est, de préférence, configurée de façon à couvrir une partie de la tête de réduction de cristallin (318) pendant son fonctionnement, cela pour éviter d'endommager par inadvertance la capsule du cristallin. La partie distale de ladite gaine (320) peut également être orientée ou positionnée de façon à diriger le flux de fluide et de matière constituant le cristallin créé par la tête rotative de façon qu'il suive un trajet préféré à l'intérieur de la capsule du cristallin. Le dispositif à sonde (302) peut comporter des moyens servant à introduire un fluide dans l'oeil et/ou à retirer un fluide et/ou des débris de l'oeil.
