Tantalum can be made into tantalum chips of various shapes and sizes, which can be implanted according to the needs of various parts of the human body, such as repairing and sealing the cracks and defects of broken cranium and limb fractures of the human body. After the tantalum piece was attached to the head and the skin grafted, over time, the new skin grew so well that the tantalum ear could hardly be seen. Tantalum is an ideal bioadaptive material in medicine. When it is in direct contact with human bone, muscle tissue and fluid, it can adapt to biological cells and has excellent affinity, almost without human stimulation and side effects. Tantalum can not only be used to make bone plates, screws and clamps for the treatment of fractures, but also can be used to repair bones with tantalum plates or tantalum chips or to replace broken bones caused by trauma.
Tantalum and tantalum foil can be used to suture nerves, muscle muscles and blood vessels up to 1.5 millimeters long. Extremely fine tantalum can replace tendons and even nerve fibers. With the development of science and technology, niobium and tantalum will be more and more widely used. Tantalum is very malleable and can be made into silk equal to or finer than a human hair. As a surgical suture line, it has the advantages of easy sterilization, less stimulation and great tensile strength. Tantalum can be used for suture of bone, tendon and fascia, as well as for extensional suture or fixation of teeth in the mouth. It can also be used as sutures for visceral surgery, or inserted into artificial eyes. It can also be used as a substitute for tendon and nerve fibers.
Because of its excellent mechanical properties and anti-fatigue properties, metal materials are suitable to be used in the field of clinical medicine as implant materials for load-bearing parts. The corrosion of materials caused by the environment in human body has influenced the wide application of metal materials in the medical field. Tantalum metal, with its excellent corrosion resistance and biocompatibility and other unique advantages, is more and more widely concerned by medical and material workers.
