Application description of medical titanium alloy strip and foil materials
Medical titanium alloy strip (usually 0.1-1.0 mm thick) and foil (less than 0.1 mm thick) are mainly suitable for manufacturing minimally invasive interventional instruments, precision implants, and medical consumables in the medical field due to their excellent biocompatibility, corrosion resistance to body fluids, and lightweight, precision cutting, and easy welding characteristics. Their core applications cover cardiovascular, orthopedic, dental, surgical, and medical aesthetics fields. Due to the difference in thickness, the two materials have their own specific applications.
1、 Application of medical titanium alloy strip
In the field of cardiovascular medicine, it can be used to manufacture support substrates for vascular stents and membrane skeletons for cardiac occluders. High precision structural components are made through precision rolling and laser cutting processes, which have both strength and flexibility, and can adapt to the needs of vascular dilation and dynamic cardiac activity, ensuring stability after implantation; In the field of orthopedics, it can be processed into micro bone plates for fracture fixation and thin connecting plates for spinal fixation systems, which are suitable for the fixation needs of narrow bone parts and reduce compression on surrounding tissues; In the field of dentistry, it can be used as a base pad for dental implants and a thin bracket for oral restorations. With its lightweight characteristics, it conforms to the anatomical structure of the oral cavity, ensuring the comfort and stability of the restoration effect; In addition, it can also be used as a cutting edge substrate for surgical instruments and as an outer reinforcement band for minimally invasive instruments, enhancing the wear resistance and structural strength of the instruments.
2、 Application of medical titanium alloy foil material
Due to its extreme thinness and stronger processability, the core is used for high-precision implant and consumable manufacturing. In the field of cardiovascular medicine, thin leaflets for artificial heart valves and inner foil layers for vascular intervention catheters can be made, which can achieve precise flexible movements and blood compatibility, reducing interference with blood flow; In the field of medical aesthetics, ultra-thin support foils for thread embedding and micro foil scaffolds for local shaping can be used to reduce postoperative foreign body sensation due to their thin, light, and soft characteristics. They also have excellent biocompatibility and fast postoperative recovery; In the field of surgery, it can be used as an ultra-thin patch substrate for visceral repair and a lubricating foil layer for minimally invasive puncture needles, suitable for the needs of fine tissue repair and minimally invasive operations; In addition, it can also be used as electrode foil layer for medical sensors and insulation foil layer for implantable medical devices, balancing biocompatibility and conductivity/insulation performance to ensure precise operation of the devices.
