Abstract

L'invention concerne un dispositif de traitement endoscope qui est apte à assurer un espace de fonctionnement et un champ de vision suffisants et qui aide à saisir une détection de distance. Ce dispositif de traitement endoscope comporte : des tubes intérieurs souples 20 dans lesquels un endoscope 2 et une pluralité d'instruments de traitement 3 sont insérés pour pouvoir se déplacer vers l'avant et vers l'arrière ; et un tube externe 30 dans lequel les tubes intérieurs 20 peuvent être insérés. Les tubes intérieurs 20 sont situés au niveau d'une partie d'extrémité distale avec des premières parties d'opération de pliage 22, 25, 28 qui, lorsque l'endoscope 2 et les instruments de traitement 3 sont avancés, plient et font saillir l'endoscope et les instruments de traitement 3 dans une direction vers la circonférence extérieure du tube extérieur 30. Des parties distales de l'endoscope 2 et les instruments de traitement 3 qui font saillie des tubes intérieurs 20 sont chacun pourvus de deuxièmes parties d'opération de pliage 2a, 3a, 70 qui plient l'endoscope 2 et les instruments de traitement 3 dans une direction vers la circonférence interne du tube externe 30.
