Abstract:
1. A medical treatment endoscope comprising: a longitudinal member including a longitudinal axis and comprising a channel along the longitudinal axis; an arm section disposed to be free to be protruded from and inserted into a distal end of the channel; a bending part disposed to a proximal end of the arm section and capable of bending; a wire member for bending the bending part; an one-end-connecting part disposed at the bending part and connected to the wire member; an other-end-connecting part disposed at the longitudinal member and connected to the wire member; and an operating part for the arm section moving relative to the longitudinal member in a protruding direction of the arm section, wherein an operation of the operating part configured to cause a drawing tension of the wire member to generate in a direction from the one-end-connecting part to the other-end-connecting part by the arm section moving relative to the longitudinal member in the protruding direction of the arm section such that the bending part is bent, and wherein the bending part includes: a viewing device disposed at a tip of the longitudinal member independent from the arm section for observing an object; an illuminating member, for illuminating light onto the object, disposed at the tip of the longitudinal member independently from the arm section; in a cross-sectional surface of the second bending part, a first axis line and a second axis line, provided at the second bending part, normal to each other, and the plurality of the first operating members are each inserted therebetween for rotating the first bending part; and in a cross-sectional surface of the second bending part, a third axis line and fourth axis line, provided at the second bending part, normal to each other, and the plurality of the second operating members are each inserted therebetween for rotating the second bending part; wherein:
