回以上入替え挿通したことを特徴とする内視鏡。 A curved section is provided in the insertion section of the endoscope and is composed of a plurality of joint rings that are connected to each other so as to be able to bend. One end is connected to the distal end side of the curved section, and the other end is connected to the operating section of the endoscope. It includes a plurality of operating wires connected to a bending operating member, and a wire support member that allows these operating wires to be inserted and supported at substantially opposite positions on the inner periphery of the node ring, and the operating wires are moved forward and backward by the bending operating member. By doing so, in the endoscope capable of bending the bending portion, the plurality of operation wires are attached to at least one wire support member at a position substantially opposite to the longitudinal axis of the bending portion within the bending portion.
An endoscope that has been replaced and inserted more than once.
