Application description of medical titanium alloy rod
Medical titanium alloy rods have excellent biocompatibility, high strength, resistance to body fluid corrosion, and good machining performance. They are mainly suitable for manufacturing implants and precision instruments that need to withstand mechanical loads and have stable structures in the medical field. The core applications cover orthopedics, dentistry, cardiology, and surgical instrument fields. The specific uses are as follows:
1、 Orthopedic field
As a core application material, it can be processed into various types of intramedullary nails for fracture fixation (such as femoral intramedullary nails, tibial intramedullary nails, humeral intramedullary nails, etc.). Through intramedullary fixation, it provides axial support for long bone fracture sites, disperses stress, promotes fracture healing, and is resistant to fluid corrosion. It can be left in the body for a long time; It can also be used to manufacture the core load-bearing components of artificial joints, such as the femoral head and stem of artificial hip joints, and the femoral condyle of artificial knee joints. Its mechanical properties match the human skeleton, ensuring the stability and service life of the joint after long-term implantation, and reducing complications such as bone resorption; In addition, customized processing of bone connecting rods, support nails, etc. can be used for bone defect repair, adapting to complex bone repair scenarios and assisting in bone structure reconstruction.
2、 Dental field
Often used as the main substrate for dental implants, different specifications of dental implants are made through processes such as bar cutting and polishing. After implantation in the jawbone, they can form a good bone bond with the bone tissue, providing stable support for the upper crown and withstanding corrosion from oral saliva, acidic and alkaline food environments, ensuring the long-term use of dental implants; At the same time, it can also be used to manufacture precision components such as support nails and connecting rods for orthodontic treatment. With high strength characteristics, it meets the mechanical traction requirements in orthodontic treatment and has excellent biocompatibility, which can avoid stimulating the oral mucosa.
3、 Cardiovascular field
It can be used as a substrate for precision instruments such as pacemaker casings and catheter sheaths, relying on its resistance to blood corrosion and good biocompatibility to adapt to complex physiological environments in the body, ensuring long-term stable operation of the instruments; It can also be used to process the support skeleton of vascular stents, the core support structure of congenital heart disease occluders, etc. By precision machining, high-strength and high-precision structural components can be made to achieve the therapeutic purpose of vascular support or defect occlusion.
4、 Surgical instruments field
It can be used to manufacture surgical bone drills, bone saws, biopsy needle cores, puncture needle rods, etc. With its high strength, wear resistance, and resistance to disinfection and corrosion (such as high temperature and high pressure steam disinfection, chemical disinfection, etc.), it ensures the stability and safety of surgical instruments during repeated use, and assists in precise surgical implementation.
