Abstract
Description
また、本発明の一態様による内視鏡は、複数の湾曲要素が長手軸方向に連設され、ワイヤを牽引することで2つの湾曲方向に湾曲可能な内視鏡湾曲部であって、それぞれの前記湾曲要素は、前記長手軸方向にわたって外表面に形成された開口と、前記開口に連続するとともに前記湾曲方向に対して45度ないし135度で交差する第1の位置に形成された第1のワイヤ収容溝を有する第1の湾曲要素と、前記開口に連続するとともに前記湾曲方向に対して225度ないし315度で交差する第2の位置に形成された第2のワイヤ収容溝を有する第2の湾曲要素と、を有し、前記第1の湾曲要素と前記第2の湾曲要素とは、前記長手軸方向において隣接して配設され、前記ワイヤは前記ワイヤ収容溝に配設された、前記内視鏡湾曲部を有するものである。
Claims (4)
