Abstract
Description
また、他の態様における内視鏡の湾曲操作機構は、内視鏡の湾曲部を駆動するための湾曲ワイヤが連結され、回転操作されることで該湾曲ワイヤを回転方向に牽引する湾曲操作部材と、この湾曲操作部材と連結され、該湾曲操作部材の回転操作により回転駆動される第1の歯車と、この第1の歯車に連結され、前記第1の歯車の回転を減速して伝達される第2の歯車を備えた減速歯車機構と、前記第2の歯車に回転方向の付勢力を加える付勢機構と、を備えており、前記付勢機構は、基端を不動部に、先端を前記第2の歯車の外径部に、それぞれ回転自在に軸支され、前記湾曲操作部材が前記湾曲部を湾曲させず略直線状態にする中立状態にあるときには、前記付勢機構の二つの軸と前記第2の歯車の回転軸とが略直線状に並ぶように配置されている。
