Application description of medical titanium alloy wire
2025-12-24
Medical titanium alloy wire material relies on excellent biocompatibility, high toughness, good braiding ability, and resistance to body fluid corrosion. It is mainly suitable for the manufacturing of implants and instruments that require flexible shaping, precision connection, or minimally invasive intervention in the medical field. Its core applications cover multiple fields such as orthopedics, dentistry, cardiovascular medicine, surgery, and medical aesthetics. Its specific uses are as follows: in the field of orthopedics, it can be processed into medical sutures for fracture fixation, tension band steel wires (such as patellar fracture fixation), orthopedic anchor sutures, etc. With good flexibility and strength, it can achieve precise fixation of bone fracture sites and soft tissue suture repair. It is also resistant to body fluid corrosion and can be left in the body for a long time, reducing the pain of secondary surgery removal; It can also be used to manufacture connecting steel wires in spinal fixation systems, achieving stable fixation of spinal vertebrae through weaving or winding, and assisting in structural reconstruction and functional recovery after spinal injury. In the field of dentistry, it is one of the core materials for orthodontic treatment, which can be made into various types of orthodontic archwires (such as round wires and square wires). With excellent elasticity and shaping memory, it provides sustained and gentle orthodontic force for teeth, guides teeth to align neatly, and has excellent biocompatibility to avoid stimulating the oral mucosa; In addition, it can also be used for suturing and fixing dental implants, connecting wires for oral restorations, etc., suitable for complex and narrow space operations in the oral cavity, ensuring the stability of the restoration effect. In the field of cardiovascular medicine, it is widely used in the manufacturing of minimally invasive interventional instruments, which can be made into woven skeletons of vascular stents (such as coronary stents and peripheral vascular stents). Through precision weaving technology, a mesh structure with good expandability and support is formed. After implantation of blood vessels, it can accurately adhere to the vessel wall, support diseased vessels and restore blood flow, and is resistant to blood corrosion and has good biocompatibility, reducing the risk of thrombosis; It can also be used as electrode lead wires for pacemakers and defibrillators. With its high conductivity and flexibility, it achieves stable transmission of electrical signals in the body and adapts to the dynamic activity needs of the heart. In the field of surgery, it can be made into medical sutures (suitable for internal organs and soft tissue suturing), puncture guide wires for laparoscopic surgery, etc. It has good flexibility and sufficient strength, which can reduce tissue damage during surgery, and is resistant to disinfection and corrosion (high temperature and high pressure steam disinfection, chemical disinfection, etc.), ensuring surgical safety; In the field of medical aesthetics, it can be used to produce protein thread core wires for buried thread lifting, support wires for nose/chin shaping, etc. With biocompatibility and degradability (some medical titanium alloy wires), facial contour lifting or local shaping can be achieved with mild postoperative reactions and short recovery cycles.
