Abstract

L’objectif de l’invention est de fournir un endoscope apte à s’adapter de manière flexible à un itinéraire menant à un site cible, l’ajustement de position de l’extrémité distale de l’endoscope tout en manipulant l’endoscope vers le site cible étant simple, sans augmenter le diamètre de l’endoscope. Cet endoscope comprend un manchon externe allongé et une unité d’élément optique disposée sur le côté interne du manchon externe. Le manchon externe comprend une couche interne constituée d’une résine souple, une couche de renfort disposée sur le côté externe de la couche interne, et une couche externe constituée d’une résine souple recouvrant la couche de renfort. L’unité d’élément optique comprend une partie transmission d’image pour une utilisation de transmission d’image, une partie transmission laser, et un faisceau de fibres d’éclairage remplissant l’espace entre la surface interne de la couche interne, la surface externe de la partie transmission d’image, et la surface externe de la partie transmission laser.
