| description | The invention provides a conveying guide wire which is characterized in that a core wire is sequentially provided with a first section, a second section and a third section in the direction from the far end to the near end of the conveying guide wire, and the diameters of the sections are sequentially increased. A metal ring is at least partially disposed at a proximal end of the first segment. The second section is at least partially sleeved with the spring, the far end of the spring is connected with the near end of the metal ring, and the diameter of the far end area of the spring is smaller than that of the near end area of the spring. According to the invention, the diameter of the far-end area of the spring is smaller than that of the near-end area of the spring, so that the fit clearance between the far-end area of the spring and the core wire is smaller, and the concentricity of the far-end area of the spring and the core wire is better. Correspondingly, the invention further provides a manufacturing |
