Medical Titanium Fasteners

From instrument fixation in minimally invasive surgery to long-term support for large orthopedic implants, from the precision assembly of in vitro diagnostic equipment to the stable connection of life support systems, medical fasteners, though often considered “tiny components,” play a crucial role in ensuring medical safety and improving treatment outcomes. With continuous breakthroughs in materials, technology, and intelligence, medical fasteners will play a vital role in a wider range of medical scenarios, providing patients with safer, more precise, and more comfortable treatment options, and driving the medical industry towards higher-quality development.

Medical fasteners must simultaneously meet three core requirements: biocompatibility, mechanical reliability, and sterility. They must avoid triggering immune rejection in the human body, while also ensuring long-term stability in complex physiological environments (such as corrosive bodily fluids and repeated stress). They must also undergo rigorous sterilization processes to ensure safe use. The technical threshold and quality standards are far higher than those of ordinary industrial products.

Orthopedics: Orthopedics is the largest application area for medical fasteners, primarily used for fracture fixation, joint prosthesis installation, and bone defect repair. Key requirements include mechanical stability, good osseointegration, and no rejection. These include orthopedic screws, plate bolts, artificial hip and knee prostheses, and dental fasteners.

Cardiovascular: Fasteners in the cardiovascular field require miniaturization and high fatigue strength. They are primarily used to secure interventional devices such as heart stents and vascular occluders, preventing them from dislodging within blood vessels.

Medical Devices: While fasteners for in vitro medical devices (such as life support equipment, diagnostic instruments, and surgical instruments) don’t come into direct contact with the human body, they must ensure long-term, stable operation. Core requirements include corrosion resistance, easy cleanability, and high reliability. These include ventilators, hemodialysis machines, biochemical analyzers, surgical forceps, and scissors.
