The design is a curved structure of tracheoscopic catheter.It is mainly composed of a main elastic spring ring,Two small spring coils,And a fixed seat,The main elastic spring coil is arranged inside the hose at the distal end of the tracheoscope catheter.The two small spring coils are arranged at the two opposite sides of the main spring coil.The two stay wires of the tracheoscope are respectively penetrated between them.The fixing seat is arranged at the farthest end of the hose.The distal ends of the two stay wires are respectively passed through the through holes on the two sides of the fixing seat and fixed.The other end of the stay wire extends to the control mechanism inside the handle.Therefore, the utility model can be used for simple operation of the linkage cable at the handle.And then the fixed seat swings in the same direction.The distal end of the catheter is bent synchronously.本創作為一種氣管鏡導管彎曲構造，主要係由一條主彈性彈簧圈、二條小型彈性彈簧圈、和一固定座所組成，其中主彈性彈簧圈係設在氣管鏡導管遠端的軟管之內部，而二小型彈性彈簧圈則設在主彈性彈簧圈內部相對的兩側位置，提供氣管鏡的二條拉線分別貫穿其間，固定座則容置於軟管的最遠端，二拉線的遠端分別穿過固定座二側的貫穿孔並固定，拉線的另端延伸結合於把手內部的控制機構，因此可利用於把手處簡易操作連動拉線，進而連動固定座同向擺動，達到使導管遠端同步彎曲之目的者。
