Machining method of micropore catheter

The invention relates to the technical field of medical instruments, in particular to a forming process of a micropore catheter, and aims at providing a machining method of the micropore catheter. According to the machining method, a micropore structure can be formed, micropores are uniform in size, and the micropores are not likely to be blocked. A steel wire and a polymer material are subjected to joint extrusion forming, the surface of the steel wire is coated with the polymer material, in other words, the steel wire is implanted in the center of the catheter, the micropores are formed after the steel wire is drawn out, the sizes of the micropores are controlled by controlling the diameter of the steel wire, meanwhile, the surface of the steel wire is spray-coated or soaked with medical silicon oil, the problems that due to the characteristics of materials, after the surface of a steel wire is wrapped by the materials, the materials easily adhere to the steel wire, and the steel wire cannot be drawn out ar
