Claims (5)
- 内視鏡の操作部に対して傾動可能に支持された湾曲レバーと、
前記湾曲レバーに設けられ当該湾曲レバーの傾動動作に連動して先端側が変位可能なアーム部と、
中継レバーと、を備え、
前記中継レバーは、
固定端側が前記操作部に対して揺動可能に支持され、前記アーム部の先端側が中継部材を介して接続される力点を中途に有するとともに、前記内視鏡の挿入部に設けられた湾曲部を湾曲動作させるための湾曲ワイヤが接続される作用点を、前記力点よりも支点から離間した位置であって、該中継レバーの長手方向において前記力点よりも自由端側の位置に有する、ことを特徴とする湾曲操作装置。 - 前記中継部材の中途に係合され、前記湾曲レバーが中立状態にあるときの前記中継部材の基端側を前記アーム部の垂直方向に対して所定角度範囲内の角度にて指向させるプーリを備えたことを特徴とする請求項1に記載の湾曲操作装置。
- 前記プーリは、前記湾曲レバーが中立状態にあるときの前記中継部材の先端側を前記中継レバーの垂直方向に対して所定角度範囲内の角度にて指向させることを特徴とする請求項2に記載の湾曲操作装置。
- 前記中継レバーの前記力点に接続する前記中継部材の長さを調整する第1のワイヤ調整部と、
前記中継レバーの前記作用点に接続する前記湾曲ワイヤの長さを調整する第2のワイヤ調整部と、を備えたことを特徴とする請求項1に記載の湾曲操作装置。 - 請求項1に記載の湾曲操作装置を前記操作部に備えたことを特徴とする内視鏡。
