Abstract
Description
図1は、本発明の実施形態に係わる、内視鏡1の構成の一例を示す図である。図2は、本発明の実施形態に係わる、内視鏡1の挿入部5の先端部材6の構成の一例を示す図である。
続いて、ガイド機構11の構成について、説明をする。
続いて、内視鏡1のガイド機構11の動作について説明をする。
実施形態及び他の変形例では、外周壁42は、外筒51の外周面と隣り合うように配置され、座屈しないように外筒51を保護するが、外周壁42と外筒内周部54とが隣り合うように配置されてもよい。
実施形態及び他の変形例では、内筒71は、内筒基端部73にガイド筒261を有しないが、内筒基端部73にガイド筒261を装着してもよい。
実施形態及び他の変形例では、固定具61及び内筒71は連結されているが、固定具61及び内筒71とが分離して構成してもよい。
