The applications of cutting-resistant tungsten wire in the medical field primarily stem from its high strength, corrosion resistance, biocompatibility, and excellent performance in precision machining. Below are some specific applications in the medical domain:
1. Manufacturing of Medical Surgical Tools
Due to its high hardness and wear resistance, cutting-resistant tungsten wire is frequently used in the production of components for surgical knives, suture needles, or other cutting instruments. Tungsten wire maintains sharpness and resists deformation, making it ideal for surgical tools requiring high precision and durability.
2. Processing of Minimally Invasive Devices
In the manufacturing of minimally invasive surgical equipment—such as endoscopes, catheters, or stents—cutting-resistant tungsten wire serves as a tool for cutting or shaping tiny components. Its fineness and tensile strength enable it to process extremely small structures while ensuring precision and reliability. For example, it excels in cutting vascular stents or forming guidewires.
3. Dental Tools
Tungsten wire is also applied in dentistry, such as in the production of dental drills or components for orthodontic devices. Its corrosion resistance and high strength allow it to withstand prolonged use in the oral environment, resisting erosion from saliva and acidic conditions.
4. Implant Manufacturing
Owing to tungsten’s excellent biocompatibility, cutting-resistant tungsten wire can be used to process certain medical implants, such as orthopedic fixation devices or components of cardiovascular implants. The wire’s ability to cut hard materials while maintaining a smooth machined surface makes it suitable for producing high-precision implants.
5. Radiotherapy and Diagnostic Equipment
Tungsten’s high density and heat resistance give it indirect applications in radiotherapy equipment, such as X-ray tubes or gamma knives. Cutting-resistant tungsten wire can be used to manufacture precision components for these devices, ensuring stability in high-temperature and high-radiation environments.
6. Surgical Robots
Due to its high density and strength, tungsten wire is utilized in precision medical devices like surgical robots. It can endure continuous motion and pressure, resist wear, and maintain high precision and strength. Unaffected by high temperatures, it withstands bodily fluids, rigorous sterilization processes, and other environmental factors, thereby extending the lifespan of critical components and ensuring the reliability and longevity of surgical robots.
