  1. The structure of the guide wire

  The guide wire is composed of inner and outer parts, and the surface layer is made by rewinding high-quality stainless steel wire on the side of the spring lathe. The steel wire is smooth, firm, and malleable. The rewinding machine must be well-proportioned, neatly arranged, and compact. This kind of spring should be able to withstand constant bending and not break under certain energy efficiency. The inner cavity of the spring management center, that is, the inside of the guide wire, is equipped with a straight and hard steel wire core, and the front of the steel wire core gradually narrows. Weld the top of the very slender wire core with the end of the spring, then weld the end of the wire core with the end of the spring, and polish it smoothly to become a very simple guide wire.

  To put it plainly, the steel wire core in the middle of the SafetyGuideWire spring is a few centimeters away from the spring, and it is not welded to the spring, making the front of the spring softer. There is also a commercial fuse steel wire with a diameter of 0.1mm or less, which is processed in parallel with the steel wire core, and its tail end is welded to the spring to ensure that a section of the capillary will not be disappointed by the spring break. This type of guide wire is divided into two types: one is a fixed steel wire core, that is, the steel wire core is welded to the end of the spring; the other is a theme movable steel wire core, whose end is welded in the handle. It can be moved, used to change the strength and shape of the front of the guide wire.

  Some guide wires are coated with a thin layer of polytetrafluoroethylene plastic film, the purpose is to make the guide wire more smooth and reduce the friction resistance with the catheter. The Teflon sheath of the more high-quality guide wire has been resolved by heparin. In addition to low sliding friction, it also has the ability to avoid blood clotting.
