Development and application of medical titanium rods and titanium rods for medical implants
The world population is nearly 7 billion. According to incomplete statistics, there are close to 400 million people with disabilities, 60 million people with physical disabilities, and 2 billion dental patients. At present, there are only 35 million implanters of biomaterial devices, and the annual joint replacement volume is about 150. Ten thousand cases, which is far from the actual number of replacements. Therefore, the market demand for biomedical materials has great potential. As the first choice of biomedical metal materials, the demand for titanium rods and titanium plates will also greatly 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 and organs or to enhance their functions. It is a new type of carrier material in materials 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 biomedical metal materials, titanium and titanium alloys have become artificial joints (hip, knee, shoulder, ankle, elbow, wrist, finger joints, etc.) and bone trauma products (intramedullary nails, steel plates, screws, etc.) by virtue of their excellent comprehensive properties. ), Spinal orthopedic internal fixation systems, dental implants, dental trays, orthopedic wires, artificial heart valves, interventional cardiovascular stents and other medical internal plant products of choice. At present, there is no better metal material than titanium alloy for clinical use. Developed countries and world-renowned suppliers of internal implant products 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 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 purpose of speedy recovery of patients.
For example, cheekbone plastic surgery mainly includes two concepts: one is a simple chiseling to reduce the outer contour of the cheekbone; the other is a three-dimensional osteotomy, which is achieved by shortening and moving the bones. Of shrinking. Zygomatic chiselectomy is generally suitable for patients with protruding anterior and lateral faces. An intraoral incision is often used to separate and expose the cheekbones under the periosteum. Special equipment is used to chisel and thin the part of the cheekbones that are designed to be removed before the operation to reduce the size. Improve facial contours. Use titanium nails and titanium plates to fix the cheekbones so that the cheekbones will not slip and cause the facial contours to lose shape, and it can better achieve the effect of cheekbones shaping! The biggest advantage of this kind of surgery is that there are no scars after the operation and it is seamless. , Leaving no trace. The difficulty of three-dimensional zygomatic osteotomy is greatly increased, which is suitable for patients with protruding zygomatic arch. In addition to the intraoral incision, an auxiliary incision is usually made in the hidden part of the hairline, or a single coronal incision is made in the scalp. After the subperiosteal separation exposes the entire cheekbone, the bone pieces of a specific size are cut according to the needs of the computer three-dimensional simulation design. Special materials such as titanium nails are used to reconnect and shape the separated bone blocks, so that the entire facial contour and shape can be changed to the greatest extent, and even the patient can achieve a "reborn" effect.
