Abstract
【解決手段】挿入部2の湾曲部2bは操作ノブ13UD,13LRを手指で操作することにより湾曲するが、操作レバー26または操作つまみ27を操作すると、操作ノブ13UD,13LRの操作に対する抵抗が最小負荷作動状態からロック状態まで変化する。負荷付与部材36,37で設定した有負荷作動状態からロック状態までは、操作ノブ13UD,13LRに内視鏡を通常操作する際に設定される負荷が作用する通常操作モードと、負荷付与部材36,37の負荷が作用しない最小負荷の状態で操作ノブ13UD,13LRを操作できる軽操作モードとの間が、操作レバー26,操作つまみ27で切り換えられる。

Claims (5)
- 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回動操作部材を有する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、前記回動操作部材に対して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、この有負荷作動状態より軽い負荷となる最小負荷作動状態とに前記回動操作部材に対する操作時の負荷を段階的にまたは連続的に変化させる負荷設定手段と、
前記負荷設定手段を、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に切り換えるモード切換部材と
を備える構成としたことを特徴とする内視鏡。 - 前記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最小負荷作動状態まで連続的または段階的に負荷を変動させるものから構成したことを特徴とする請求項1記載の内視鏡。
- 前記モード切換部材は、前記通常操作モードと前記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で構成したことを特徴とする請求項1記載の内視鏡。
- 前記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と前記有負荷作動状態との間で連続的または段階的に負荷を変動させるものであり、また前記最小負荷作動状態は、前記回動操作部材の操作方向に向けての操作力を増強させる操作力アシスト機構から構成し、前記モード切換手段は、前記操作力アシスト機構を非作動状態と作動状態とに切り換える切換手段で構成したことを特徴とする請求項1記載の内視鏡。
- 前記操作力アシスト機構は、前記湾曲操作手段に設けたモータまたは前記湾曲部に設けた人工筋肉から構成したことを特徴とする請求項4記載の内視鏡。
