Abstract

L’invention a pour objet une canule dans laquelle le diamètre intérieur d’un élément de forme cylindrique est étroit afin de ne pas limiter la liberté de mouvement d’une tige, telle celle d’un dispositif de commande, et de ne pas limiter le mouvement d’un instrument d’opération à l’extrémité antérieure de la tige, tel le dispositif de commande. La canule présente ledit élément de forme cylindrique (2) dans lequel une fente (3) continue d’une extrémité à l’autre est pratiquée. La fente (3) est formée de manière rectiligne parallèlement à l’axe central de l’élément de forme cylindrique (2) et les parties de ce dernier aux deux extrémités où est pratiquée la fente (3) ont une forme (4, 5) coupée en direction des extrémités de l’autre côté.
