Abstract

La présente invention concerne un tube flexible destiné à être utilisé dans un endoscope médical. Le tube flexible est doté d'un canal s'étendant dans la direction axiale. Le canal est divisé en un canal de commande de guidage (1), un canal de détecteur de lumière et d'imagerie (2) et un canal de travail (3). L'aire transversale du canal de travail (3) est supérieure à l'aire transversale du canal de commande de guidage (1) ou à celle du canal de détecteur de lumière et d'imagerie (2). La présente invention rassemble le canal de travail et un canal de rinçage en un seul canal, fournissant une aire transversale plus grande, une plus grande plage disponible pour le mouvement durant l'opération, une plus grande commodité dans le fonctionnement des équipements, un flux plus important, alors que la conception à trois canaux-cavités permet une fabrication plus simple, de faibles coûts de fabrication, des coûts maintenus et une promotion plus facile.
