Claims (3)
- 本体操作部に挿入部を連結して設け、この挿入部を先端から内視鏡観察手段を設けた先端硬質部、湾曲部及び軟性部となし、前記本体操作部には、前記湾曲部に連結した湾曲操作用の操作ワイヤの基端部を連結したプーリを回転させる軸を回動操作するための湾曲操作手段が設けられ、この湾曲操作手段で前記湾曲部を湾曲操作可能な構成とした内視鏡において、
前記湾曲操作手段は、この湾曲操作手段の回動操作に対する負荷を与える回動操作部材を有し、この回動操作部材には押圧部材が設けられ、また前記軸には受け部材が設けられ、
前記受け部材には、前記回動操作部材の回動動作により、前記押圧部材に押圧されることによって、前記湾曲操作手段に負荷を生じさせながら前記湾曲部を湾曲させる操作が可能な有負荷作動状態となる負荷付与部材と、前記湾曲部を所定の姿勢状態に保持させる最大負荷が与えられるロック状態とする摩擦部材とが装着され、
前記回動操作部材は、前記押圧部材と前記受け部材との間を前記摩擦部材及び前記負荷付与部材による負荷を生じさせずに回動可能な最小負荷作動状態と、前記押圧部材と前記受け部材との間に前記負荷付与部材による所定の負荷が与えられた状態で前記湾曲部を湾曲させる操作が可能な有負荷作動状態と、前記摩擦部材により前記押圧部材と前記受け部材とが相対回動不能となったロック状態とに変位可能な構成としたことを特徴とする内視鏡。 - 前記回動操作部材の操作時に、前記負荷付与部材による負荷を前記ロック状態から前記最小負荷作動状態まで連続的または段階的に変動させる構成としたことを特徴とする請求項1記載の内視鏡。
- 前記回動操作部位材は負荷設定手段を構成するものであり、この負荷設定手段は、前記回動操作部材に対して、前記ロック状態から前記有負荷作動状態までの範囲の負荷を作用させる通常操作モードと前記回動操作部材に対して前記最小負荷作動状態とする軽操作モードとの間の移行をクリック感触として検出可能なクリック部材からなるモード切換手段を備える構成したことを特徴とする請求項1記載の内視鏡。
