Angle-adjustable visual endotracheal catheter

The invention relates to the technical field of tracheal intubation, in particular to an angle-adjustable visual endotracheal catheter which comprises a catheter body, an angle adjusting chain, a display screen and a miniature camera mounted at the front end of the catheter body. An interlayer cavity is formed in an inner cavity of the catheter, and the angle adjusting chain is installed in the interlayer cavity. The angle adjusting chain is composed of a plurality of chain links rotationally connected end to end in sequence, an outer elastic band and an inner elastic band, wherein the outer elastic band and the inner elastic band penetrate through the chain links in sequence. A reel containing cavity is formed in the rear end of the guide pipe, a winding shaft is arranged in the reel containing cavity, a damping ring is arranged between the reel containing cavity and the winding shaft, and the winding shaft is rotationally matched in the damping ring. The intubation process is visible, the curvature of the c
