[0045] Among them, the sliding seat 30 moves from one end of the reference steel wire 200 to the other end thereof, and the wire winding assembly 40 rotates around the axis of the reference steel wire 200, so that the peripheral wall of the reference steel wire 200 is completely wrapped around the multiple strands of the metal wire core, so that the multiple strands of the metal wire core wrapped around each other form a guide wire.

[0046] In this embodiment, the medical spring, taking the guide wire as an example, the winding device 100 of the fully automatic medical spring of the present invention can be used to produce the guide wire. The guide wire is one of the main tools of the percutaneous puncture catheter. The guide wire plays a guiding and auxiliary role in the catheter, helping the catheter to enter the blood vessels and other cavities, and guiding the catheter to reach the lesion smoothly. The guide wire consists of an inner and outer part, and the outer layer is wound with high-quality stainless steel wire on a spring rotating bed. The steel wire needs to be smooth, tough, and elastic, and the winding must be uniform and tight, neatly arranged, and loose and consistent. This spring should be able to withstand repeated bending and will not break under a certain force. The cavity in the center of the spring, that is, the inside of the guide wire, is equipped with a hard steel wire core, and its front end gradually becomes thinner. The tip of the very thin steel core is welded to the end of the spring, and then the tail of the core is welded to the end of the spring to make it polished and smooth, becoming the simplest guide wire.
