The present invention is an endoscope mirror flexible catheter structure, which is mainly designed to utilize a plurality of unit bodies that can be easily engaged with each other, and is integrally disposed inside the end hose portion of the endoscope catheter to provide smooth operation. The unit body is a column structure, the shaft center is provided with a circular working hole and two laterally extending slots, and two independent through holes are arranged, and both ends of the column are arranged from the middle to the outside. An inclined surface having an oblique angle, wherein one end is provided with two opposite lug pieces, the outer side of each of the two lug pieces is provided with a convex portion, and the other end is provided with two C-shaped clips, so the two unit body can be borrowed The C-shaped clip and the convex portion of the circular protrusion are pivotally connected to each other in a swingable state, and the swinging range is at a position where the upper and lower inclined surfaces of the unit body are in contact with each other, and the surface is in contact with the surface to achieve control of mutual card. The angle of the swing between each two unit body is obtained, and the smoothing effect of the end of the endoscope tube bending is smoothly obtained.本創作為一種內視鏡可彎曲導管構造，主要設計以利用多數個可簡易相互卡合的單元體，整體設置於內視鏡導管遠端軟管部的內部，提供操作順暢之效果，其各單元體為柱體構造，軸心設有貫穿的圓形工作孔道和側向延伸的二個槽孔，另設有二獨立貫穿的線孔，於柱體的兩端面均設為由中間向外呈下斜角度的傾斜面，而其中一端設有二相對的凸耳片，二凸耳片的外側各設有一圓凸部，另一端相對位置則有二C形夾，故二單元體可藉由C形夾和圓凸部的簡易卡合而樞接，呈可擺動之狀態，其擺動的範圍係介於單元體上下斜面接觸之位置，為面與面的接觸定位，以達到控制相互卡合的每二單元體間擺動的角度，並獲得順暢操作內視鏡導管尾端彎曲的穩定效果。
