Fig. 1 is a schematic structural view of a disposable catheter with a fixing ring according to the present invention, fig. 2 is a schematic exploded structural view of the fixing ring according to the present invention, and fig. 1 to 2 show a preferred embodiment of the disposable catheter with a fixing ring, which comprises: the device comprises a catheter 1, a fixing ring 2, a fixing mechanism 3 and a telescopic mechanism 4; the cover is equipped with solid fixed ring 2 on the pipe 1, is provided with telescopic machanism 4 in solid fixed ring 2, and one side of solid fixed ring 2 is provided with fixed establishment 3, and fixed establishment 3 is connected with telescopic machanism 4, and one side of solid fixed ring 2 still is provided with go-between 5, and the one end of go-between 5 is connected with telescopic machanism 4's one end. The fixing ring 2 is sleeved on the catheter 1 and fixes the catheter 1 together with the connecting ring 5. The fixing ring 2 and the catheter 1 are made of plastic materials, so that the elasticity of the catheter 1 and the fixing ring 2 is increased, and the catheter cannot be broken off due to bending when in use.

Further, as a preferred embodiment, the telescopic mechanism 4 includes a telescopic rod 41, the fixing ring 2 is provided with a placing hole 21, the telescopic rod 41 is disposed inside the placing hole 21, the telescopic rod 41 can slide in the placing hole 21, one end of the telescopic rod 41 extends out of the placing hole 21, and one end of the connecting ring 5 is connected to one end of the telescopic rod 41. One side of the fixing ring 2 away from the placing hole 21 and the other end of the connecting ring 5 are integrally arranged. When the catheter 1 needs to be fixed to a position having a different diameter, the fixing mechanism 3 is first released, the telescopic rod 41 is pulled to extend or shorten the length of the telescopic rod 41 outside the placement hole 21 to a desired position, and finally the fixing device is fixed, thereby fixing the guide rail.
