The world population is nearly 7 billion. According to incomplete statistics, there are nearly 400 million disabled, 60 million limb disabled, and 2 billion dental patients. At present, there are only 35 million implanted biomaterial devices, and the annual joint replacement is about 150. The number of cases is far from the number of people who actually need to be replaced. Therefore, the market demand potential of biomedical materials is huge. As the first choice of biomedical metal materials-the demand for titanium rods and plates will also increase, so it is imperative to increase the research and development of medical titanium alloy materials.

Biomedical titanium is an important branch of materials science. It is a new carrier material with high technical content and high economic value for diagnosis, treatment or replacement of human tissues, organs or enhancement of its function. New areas of development. Biomedical titanium rods make greater contributions to exploring the mysteries of human life and ensuring human health and longevity.

Among biomedical metal materials, titanium and titanium alloys have become an artificial joint (hip, knee, shoulder, ankle, elbow, wrist, knuckle, etc.) and bone trauma products (intramedullary nails, steel plates, screws, etc.) due to their excellent comprehensive properties. ), Spinal orthopedic internal fixation systems, dental implants, dental trays, dental orthopedic filaments, artificial heart valves, interventional cardiovascular stents and other medical endogenous plant products of choice. At present, there is no better metal material for clinical use than titanium alloy. Developed countries and world-renowned body implant product suppliers have attached great importance to the research and development of titanium alloys, and introduced a series of new medical titanium alloy materials, including bioactive titanium alloy bionic materials, in the surface treatment of medical titanium alloy materials. Many patented designs and developments have also been made to give medical titanium alloy materials better biological activity to meet the physiological needs of the human body, so as to achieve the goal of early recovery for patients.

For example, sacral plastic surgery mainly includes two concepts: one is simple sacral chiseling to reduce the outer contour of the sacrum; the other is three-dimensional osteotomy, which is achieved by shortening and moving the sacrum. Shrinking. Sacral chiseling is generally suitable for patients with prominent anterolateral sides of the face. Intraoral incisions are often used to separate and expose the sacrum under the periosteum. Special equipment is used to chisel the sacral part that is designed to be removed before surgery to reduce the thickness. Facial contours improve the appearance of the face. The use of titanium nails and titanium plate fixation is to prevent the patella from slipping and cause facial contour loss, and it can better achieve the effect of patella shaping! The biggest benefit of this operation is that it does not leave scars after surgery, and it is seamless. No trace left. The three-dimensional osteotomy of the sacrum is significantly more difficult and suitable for patients with prominent sacral arch. In addition to the intraoral incision, a hidden incision in the hairline is usually required, or a single incision in the scalp is made. After the periosteum is separated and exposed to expose the entire sacrum, the bone mass of a specific size is removed in accordance with the needs of 3D computer simulation design. Then, the special bone and other materials are used to reconnect and shape the separated bone pieces, so that the contour and shape of the entire face can be changed to the greatest extent, and even the patient can achieve the effect of "reborn".
