Medical guide wire, as an accurate guiding tool, can help doctors accurately locate lesions in complex anatomical environments and improve the success rate of surgery. This article will provide a detailed introduction to the working principle, types, applications, and development prospects of medical guide wires, so that readers can better understand this key tool. 1、 The working principle of medical guide wire is a device used to accurately guide and insert medical devices, such as catheters, implantators, etc. Its working principle is to insert a guide wire along a human pipeline or incision, and after reaching the target position, the doctor guides other medical devices into the human body through the guide wire, achieving accurate lesion localization. The softness and toughness of the guide wire determine its smoothness and guiding effect in the human body. 2、 The type of medical guide wire Metal guide wire: Metal guide wire has high hardness and bending resistance, and is commonly used to guide harder medical devices, such as implants, catheters, etc. But its softness is poor, which can easily cause discomfort to the human body. Soft guide wire: Soft guide wire has good flexibility and compliance, and is suitable for pipelines with large curvature, such as coronary arteries. But its bending resistance is weak and is not suitable for guiding harder medical devices. Special guide wire: special
