Abstract

La présente invention concerne un endoscope qui comprend un ensemble caméra, un tube de raccordement (20B), un élément de préhension (30B) et une unité adaptateur (40B). L'ensemble caméra comprend un module de caméra de visualisation principale (11B) et un module de caméra de visualisation latérale (12B). L'endoscope comporte un petit diamètre extérieur de 3,8 mm. Il peut donc être utilisé pour inspecter l'intérieur d'un canal de petite taille. En outre, l'endoscope peut inspecter en même temps l'environnement au niveau d'un côté avant et d'un côté latéral de l'endoscope, ce qui permet de réaliser une inspection en vision totale sans courber l'endoscope, réalisant ainsi une inspection plus complète et plus pratique.
