The present invention is an endoscope catheter bending control device, the structure comprising a handle, which is composed of an upper cover and a lower cover. A rotating wheel is arranged inside the handle, the rotating wheel has a rotating shaft, and the two ends of the rotating shaft are respectively arranged On the two arc-shaped grooves on both sides of the lower cover, the rotating wheel is in a rotatable state, and a spring is respectively arranged in the lower hole of the two curved grooves, and has an elastic force for pushing the top of the rotating shaft, and the control is located above the handle. The piece is coupled with the rotating wheel, and the outer part of the rotating wheel is further provided with a curved piece, which can be combined with the inner side surface of the circular arc portion of the upper cover, and one end of the two pulling wire is extended and coupled to the rotating wheel, so that the simple The control piece is moved to achieve the bending of the outer end of the catheter and positioning at any angular position to achieve the progress of the creation.本創作為一種內視鏡導管彎曲控制裝置,其構造包含有一把手,由上蓋和下蓋組合而成,一轉輪,設於把手的內部,轉輪具有一轉軸,轉軸的兩端分別跨設於下蓋兩側的二弧形槽上,使轉輪呈可轉動的狀態,二弧形槽的下方孔內分別設有一彈簧,具有將轉軸向上推頂的彈力,而位在把手上方的控制片與轉輪結合連動,轉輪的外部另設有一弧形片,可對合於上蓋圓弧部的內側表面,二拉線的一端係延伸結合於轉輪上,因此,可藉由簡易的移動控制片,即達到使導管外端彎曲,以及在任意角度位置定位之,以達成本創作之進步性。
