Medical field titanium alloy titanium alloy used in the manufacture of implanted medical devices, prosthesis or artificial organs and adjuvant therapy equipment. Mainly titanium, titanium 5 aluminum 2.5 tin, ELI titanium-6 aluminum, 4 vanadium and other alloys. They have mechanical properties close to human bones, high strength, strength is far superior to titanium, also has resistance to fatigue, and excellent corrosion resistance and biocompatibility. Widely used for a variety of artificial joints, bone fixation devices, dentures, dental inlay, fixed bridges. Bone 6 aluminum 4 vanadium

, Titanium the kernel ceramic bone

A could be used for the body of ceramic bone available in Shanghai. CAS Shanghai Institute of Ceramics, researchers say, it will benefit many patients in the near future.

Chinese Academy of Engineering Ding Chuanxian said, the "kernel" of ceramic bone metal titanium alloy, the texture is very hard, Waipi ceramic "coat". This layer "coat" is the high temperature of 20,000 degrees Celsius with high-speed spray from plasma. In addition to the similar shape with human bone, but also with the human body "harmony." The researchers produce X-rays: the injured puppy implanted ceramic bone, a few months after the surrounding muscles start its harmonious connected to the new and old bones gradually extended until blend. This is mainly because the main inorganic component similar ceramic the bone ceramic coating with human bone tissue.

According to reports, China's annual all kinds of accidents, diseases of bone defects or bone injury were approximately 300 million people, the bones do not sound the crowd of 1000 people, our clinical artificial bone is mostly made of metal, the lack of biological activity and blending, and with good biological activity and mechanical properties, is the biggest advantage of ceramic bone. It has varieties of artificial knee, tibia, color white, slightly the tweezers knock up the issue clank sound. The researchers said that the bone once put ceramic "coat" the body as "insiders" to accelerate the bone healing and promote tissue growth.

Second, the artificial hip joint

Artificial hip, an artificial joint, modeled on the structure of the human hip. Refers from the upper end of the thigh bone inserted a metal rod, the peak of the staff have a metal ball, can replace the top of the femur. Cement in hip nest in a plastic mortar, metal balls embedded in a mortar. Today there are hundreds of thousands of patients fitted joint.

1, material: femoral head shank were used titanium alloys, cobalt-chromium-molybdenum alloy, ultra-low carbon stainless steel manufacturing, plastics within the acetabulum, the acetabular nontoxic ultra high molecular weight polyethylene manufacturing, metal cup with titanium alloy (titanium alloy with the cobalt-chromium-molybdenum alloy femoral head handle) and ultra-low carbon stainless steel.

2, composed of:

a. unipolar femoral head handle;

b. unipolar total hip femoral head handle and plastic hip acetabular components;

c double-headed half hip femoral head handles, plastic mortar and metal cup;

d double acting mortar composition of total hip femoral head handles, plastic mortar, metal cup and plastic hip.

3, the processing method:

Titanium alloy products blanks using hot isostatic processing methods. Casting processing method for cobalt-chromium-molybdenum alloy, stainless steel forging processing method, as subsequently machined, and subjected to a surface treatment is made.
