Development and application of titanium rods for medical and medical implants

The world population is nearly 7 billion, according to incomplete statistics, the disabled close to 400 million, limb disabled 60 million, dental patients 2 billion, the current biomaterial device implant only 35 million people, the annual number of joint replacement about 1.5 million cases, and the actual need for replacement is far from the number of people. Therefore, the market demand for biomedical materials has huge potential. As the first choice for biomedical metal materials - titanium rod and titanium plate demand 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, is used to diagnose, treat or replace human tissues, organs or improve their function, with high technical content and high economic value of new carrier materials, is a new field of material science and technology is developing. Biomedical titanium rods make greater contributions to exploring the mysteries of human life and ensuring human health and longevity.

In biomedical metal materials, titanium and titanium alloys with excellent comprehensive properties, It has become the preferred material for artificial joints (hip, knee, shoulder, ankle, elbow, wrist, knuckle, etc.), bone trauma products (intramedullary nails, plates, screws, etc.), spinal orthopedic internal fixation systems, dental implants, dentures, orthopedic wires, artificial heart valves, interventional cardiovascular stents and other medical endoplant products. 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 alloy, and have launched a series of new medical titanium alloy materials, including titanium alloy bionic materials with biological activity, and have also done a lot of patented design and development in the surface treatment of medical titanium alloy materials. Give medical titanium alloy material 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 cheekbone chiselling to reduce the external outline of the cheekbone; The other type is three-dimensional osteotomy, which reduces the zygomatic bone by shortening and moving the bone. Cheekbone chiselling is generally suitable for patients with anterolateral facial protrusion. Intraoral incision is often used to separate and expose cheekbones under periosteal, and special instruments are used to chisel and thin the cheekbones designed to be removed before surgery, so as to reduce the external contour of the face and improve the facial shape. The use of titanium nails, titanium plate fixation is in order to cheekbones will not cause slip, resulting in facial contour loss, but also can better achieve the effect of cheekbone shape! The best thing about this surgery is that it leaves no scars, it's seamless, it leaves no marks. However, the difficulty of zygomatic three-dimensional osteotomy is greatly increased, and it is suitable for patients with prominent zygomatic arch. In addition to the intraoral incision, an auxiliary incision is usually made in the hidden part of the hairline, or a coronal incision is made only in the scalp. After the subperiostum separation and exposure of the entire cheekbone, bone blocks of specific size are cut off according to the three-dimensional simulation design of the computer, and special materials such as titanium nails are used to reconnect and shape the separated bone blocks, so as to maximize the change of the entire facial contour and shape. Even let the patient achieve the effect of "transformation".
