Abstract

Segment réutilisable d'une poignée d'endoscope, poignée d'endoscope et endoscope. Le segment réutilisable de la poignée d'endoscope comprend une première coque (100), des premières tiges de poussée (310), un mécanisme d'entraînement (200) et un élément élastique (320). Les deux premières tiges de poussée (310) sont agencées de façon mobile à l'intérieur de la première coque (100). Chacune des deux premières tiges de poussée (310) est reliée au mécanisme d'entraînement (200). Le mécanisme d'entraînement (200) entraîne les deux premières tiges de poussée (310) à se déplacer de manière synchrone dans différentes directions. L'élément élastique (320) relie la première coque (100) et les premières tiges de poussée (310), amenant les extrémités éloignées des deux premières tiges de poussée (310) à venir en butée l'une contre l'autre et à former une partie d'accueil. Par l'action élastique de l'élément élastique (320), les extrémités éloignées des deux premières tiges de poussée (310) viennent en butée l'une contre l'autre et forment une partie de réception. Lorsqu'un opérateur réceptionne le segment réutilisable à un segment jetable, il est seulement nécessaire de réceptionner la partie de réception avec l'extrémité proche du segment jetable. Par rapport à l'état de la technique où le segment réutilisable a au moins deux parties de réception correspondant à des composants de transmission de force, le nombre de parties de réception est réduit et la difficulté de réception du segment réutilisable avec le segment jetable est réduite.
