Application Of Medical Titanium Alloy Materials In Medical Fields Such As Artificial Joints And Spinal Orthopedics

The world's population is nearly 6.5 billion. According to incomplete statistics, there are nearly 400 million disabled people, 60 million physically disabled people, and 2 billion dental patients. Currently, there are only 35 million biomaterial device implants, and about 1.5 million joint replacements are performed every year. Ten thousand cases, far from the actual number of replacements. Therefore, the market demand for biomedical materials has huge potential. As the first choice for biomedical metal materials-titanium rods and titanium plates, the demand will also increase greatly. Therefore, it is imperative for medical titanium rod manufacturers to increase the research and development of medical titanium alloy materials.

Biomedical titanium is an important branch of material science. It is a new type of carrier material with high technical content and high economic value for diagnosis, treatment or replacement of human tissues, organs or enhancement of their functions. It is an ongoing process in material science and technology. new areas of development. Biomedical titanium rods have made greater contributions to exploring the mysteries of human life and ensuring human health and longevity.

Among the biomedical metal materials, titanium and titanium alloys are used in artificial joints (hip, knee, shoulder, ankle, elbow, wrist, knuckles, etc.), bone trauma products (intramedullary nails, plates, screws, etc.) due to their excellent comprehensive properties. ), spinal orthopedic internal fixation systems, dental implants, dental trays, dental orthopedic wires, artificial heart valves, interventional cardiovascular stents and other medical implant products. At present, there is no better metal material than titanium alloy for clinical use. Developed countries and world-renowned implant product suppliers attach great importance to the research and development of titanium alloys, and have launched a series of new medical titanium alloy materials, including biologically active titanium alloy bionic materials, in terms of surface treatment of medical titanium alloy materials A lot of patented designs and developments have also been done to endow medical titanium alloy materials with better biological activity to meet the physiological needs of the human body, so as to achieve the purpose of early recovery of patients. For example, cheekbone plastic surgery mainly includes two concepts: one is simple chiseling of the cheekbone to reduce the outer contour of the cheekbone; the other is three-dimensional osteotomy, which shortens and moves the bone to reach the shrinking. Zygoma chipping is generally suitable for patients with anterior and lateral protruding faces. Intraoral incisions are often used to separate and expose the zygoma under the periosteum. Special instruments are used to chisel and thin the part of the zygoma designed to be removed before surgery, thereby reducing the size of the zygoma. Contours the face and improves the shape of the face. The use of titanium nails and titanium plate fixation is to prevent the cheekbones from slipping, causing facial contours to lose shape, and to better achieve the effect of cheekbone shaping! The biggest advantage of this surgery is that it does not leave scars after surgery, and it is seamless , leaving no trace. The difficulty of three-dimensional zygomatic osteotomy is greatly increased, and it is suitable for patients with zygomatic arch protrusion. In addition to the intraoral incision, an auxiliary incision is usually made at the hidden part of the hairline, or a coronal incision is made in the scalp alone. After the subperiosteal separation exposes the entire zygomatic bone, a specific size of bone is removed according to the computer three-dimensional simulation design. Then use special materials such as titanium nails to reconnect and reshape the separated bone fragments, so that the entire facial contour and shape can be changed to the greatest extent, and even the patient can achieve a "reborn" effect.
