Titanium is a very common material, and the titanium sponge is 99.9% pure. Physical and chemical properties of titanium is very stable, will not be absorbed by human body, contact with body fluids and drug also won't happen chemical reaction, also won't ionization, also does not react with the body's musculoskeletal, thus known as "metal". Because titanium is "pro-biological", titanium can resist the corrosion and non-toxicity of secretions in human body, and it is suitable for any sterilization method. Therefore, it is widely used in the manufacture of medical devices, and it is used to manufacture the hip, knee, shoulder joint, side joint, skull, active heart valve and bone fixation clip.
Biomedical titanium (base material: medical titanium rods, medical titanium plate, medical titanium wire) is an important branch of medical material science, mainly used for the treatment or replace the body's tissues and organs or improve its function, is a high technology content and high economic value of new carrier materials. When the new muscle fiber ring is wrapped around these "titanium bones", the titanium bones begin to maintain normal human activity. Titanium is widely distributed in the human body. The content of normal human body is no more than 15mg per 70kg. Its role is not clear. But the role of titanium in stimulating phagocytes and boosting immunity has been confirmed. The properties of titanium itself are of high hardness and light and do not rust, or cause metal allergy to stable metal. Titanium has special current characteristics, which can have beneficial physiological effects on human experience, and its chemical stability will not change or deteriorate in time. In recent 10 years, biomedical materials and products market growth rate remained at about 30%, is expected in the next 10 years to 20 years, including medical metal materials, medical equipment industry will achieve pharmaceutical products market scale, will become the pillar industry of the world economy in the 21st century. According to incomplete statistics, disabled people around the world is close to one over twelve of the world's population, 60 million, limb disabled dental patients with close to 2 billion, the current surgical implantation of only 35 million people, each year about 1.5 million cases, joint replacement quantity and the amount of actual need replacement is far. Therefore, the potential demand of biomedical materials market is huge. As the first choice for biomedical materials, the demand for medical titanium and titanium alloy will also increase, so it is imperative to increase the research and development of medical titanium.
