Guide wire selection

Medical guide wires are used in clinical practice to guide and push various medical devices to the lesion site. When selecting medical guide wires, it is important to pay attention to the following key factors to ensure their effectiveness and safety during surgical operations.

1. Hydrophilic coating

Hydrophilic coating is a special layer of coating on the surface of medical guide wires, which has good lubrication and reduces friction. Hydrophilic coating can reduce the friction between the guide wire and the vascular wall when passing through blood vessels, reduce the risk of vascular damage, and reduce the possibility of the guide wire being adhered to by blood or thrombus.

2. Soft conduit material

The softness of the guide wire is directly related to its flexibility and controllability in vascular bends or narrow channels. The soft material of the catheter can make it easier for the guide wire to follow the curve of the blood vessel, reduce trauma and friction at bends, and make it easier to pass through narrow channels.

3. Short shoulder design reduces excess expansion

The shoulder of the medical guide wire is the part where the guide wire is connected to other instruments, and its design is also very important. The short shoulder design can reduce the expansion between the guide wire and other instruments, reduce the resistance and trauma generated by the guide wire when crossing narrow channels, and improve the passability and safety of the guide wire.
