Abstract

L'invention concerne un ensemble de positionnement (10) permettant de retenir, de positionner et d'exposer au moins partiellement la cornée d'un oeil au cours d'une intervention chirurgicale, l'oeil étant disposé dans un accès oculaire rétréci de manière latitudinale. L'ensemble de positionnement (10) comprend un segment de positionnement (20) présentant une plaque de retenue (23) dotée d'une ouverture (25) définie de manière à recevoir et exposer la cornée (C) de l'oeil, ainsi qu'un élément de bride (24) disposé autour de l'ouverture (25), à faible distance d'un rayon latitudinal de celle-ci, et structuré de manière à venir en prise avec oeil. L'ensemble de positionnement (10) comprend en outre un ensemble d'aspiration (30) associé au segment de positionnement (10) permettant de fixer, au moins temporairement, le segment de positionnement (20) sur l'oeil, l'ensemble d'aspiration (30) comprenant un orifice à vide (32) s'étendant de manière verticale à partir du segment de positionnement (10) et étant incliné vers l'extérieur par rapport à un tracé de guidage (40) disposé d'une seule pièce sur la plaque de retenue (23), de manière à définir un chemin de coupe arqué destiné à un ensemble de tête de coupe de microkératome (15). L'invention concerne enfin un ensemble de pivot comprenant au moins un élément de montant (50) définissant un axe de pivot autour duquel un ensemble de couplage pivote, ainsi qu'une commande d'origine de coupe placée au niveau de l'élément de montant (50), de manière à définir un point d'origine au niveau duquel un mouvement, et par conséquent la coupe, de l'ensemble de tête de coupe (15) commence.
