Application description of medical titanium alloy rods
2025-12-24
Medical titanium alloy rods, with excellent biocompatibility, high strength, resistance to body fluid corrosion, and good machining performance, are mainly suitable for the manufacture of implants and precision instruments that require mechanical loads and stable structures in the medical field. The core applications cover orthopedics, dentistry, cardiovascular diseases, and surgical instruments. The specific uses are as follows: In the field of orthopedics, 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.), providing axial support for long bone fracture sites through intramedullary fixation, dispersing stress, promoting fracture healing, and being resistant to body fluid corrosion and 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. With mechanical properties that match the human skeleton, it ensures the stability and service life of the joint after long-term implantation, reducing complications such as bone resorption; In addition, customized bone connecting rods, support nails, etc. can be used for repairing bone defects, adapting to complex bone repair scenarios and assisting in the reconstruction of bone structures. In the field of dentistry, the main substrate commonly used for dental implants is made into different specifications of implant materials through processes such as bar cutting and polishing. After implantation in the jawbone, it can form a good bone bond with the bone tissue, providing stable support for the upper crown and resisting 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, avoiding irritation of the oral mucosa. In the field of cardiovascular medicine, it can be used as a substrate for precision instruments such as pacemaker casings and catheter sheaths. With its resistance to blood corrosion and good biocompatibility, it adapts 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 treatment goal of vascular support or defect occlusion. In the field of surgical instruments, 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 (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.
