Title
(EN) FLEXIBLE ENDOSCOPE
(FR) ENDOSCOPE FLEXIBLE
Abstract
(EN)
An endoscope includes a handle connected to a flexible, steerable, kink- resistant insertion tube. An endoscope insertion tube may include a shaft, a lower durometer section proximate to a distal end of the shaft, and a higher durometer section positioned between the lower durometer section and a medium durometer section. The endoscope insertion tube may further include a fourth thermoplastic laminate section proximate to a proximal end of the shaft and having a higher durometer. A method of making an endoscope insertion tube may include inserting a mandrel with one, two, or more lateral slots and a liner into a shaft, wherein the liner is positioned between the mandrel and the shaft, bonding a bonded portion of the liner to an inner surface of the shaft, separating other portion(s) of the liner from the shaft, and inserting a first deflection wire in a gap between the shaft and the unbonded portion(s) of the liner.

L'invention concerne un endoscope comprenant une poignée reliée à un tube d'insertion flexible, dirigeable et résistant à la torsion. Un tube d'insertion d'endoscope peut comprendre un arbre, une section de dureté au duromètre inférieure à proximité d'une extrémité distale de l'arbre, et une section de dureté au duromètre supérieure positionnée entre la section de dureté au duromètre inférieure et une section de dureté au duromètre intermédiaire. Le tube d'insertion d'endoscope peut en outre comprendre une quatrième section de stratifié thermoplastique à proximité d'une extrémité proximale de l'arbre et ayant une dureté au duromètre plus élevée. Un procédé de fabrication d'un tube d'insertion d'endoscope peut comprendre les étapes consistant à insérer un mandrin avec une, deux ou plus de deux fentes latérales et une doublure dans un arbre, la doublure étant positionnée entre le mandrin et l'arbre, lier une partie liée de la doublure à une surface intérieure de l'arbre, séparer une ou des autres parties de la doublure de l'arbre, et insérer un premier fil de déviation dans un espace entre l'arbre et la ou les parties non collées de la doublure.
