Abstract
【解決手段】先端部本体2の凹部8内に配置されている駆動アーム10と凹部8の表面を塞ぐ蓋状部材13の内面との干渉を避けるための第1の面取り部15を駆動アーム10の全幅にわたって形成すると共に、駆動アーム10が遠隔操作によって回動したときに蓋状部材13の内面との干渉を避けるための第2の面取り部16を、第1の面取り部15の稜線によって形成される角部分のみに形成した。
【選択図】 図1
Description
図3は側方視型内視鏡の先端部を示しており、可撓管状の挿入部1の最先端部分に連結された金属製の先端部本体2にプラスチック製の先端キャップ3が被せられている。先端キャップ3は先端部本体2に対して着脱することが可能であり、図4には、先端キャップ3が先端部本体2から取り外された状態が図示されている。
