How can medical titanium bars be used in medical treatment?
As a new material, titanium bars for medical use have been used for decades in the pharmaceutical industry, surgical instruments, human implants and other fields in China and the world, and have achieved great success.
The use of titanium and titanium alloy to make artificial joints, bone plates and screws has been widely used in clinical practice. Also used for hip joint (including femoral head), knee joint, elbow joint, metacarpophalangeal joint, interphalangeal joint, inferior? Bones, artificial vertebrae (spinal orthopedics), pacemaker casings, artificial hearts (heart valves), dental implants, and titanium mesh in cranial reconstruction.
The requirements for implant materials can be classified into three aspects: the biocompatibility between the material and the human body, the corrosion resistance of the material in the human body environment and the mechanical properties of the material. As a long-term implant material, there are seven specific requirements as follows:
The corrosion resistance;
Excellent mechanical properties and fatigue properties;
Low modulus of elasticity;
Good wear resistance in the assembly;
A satisfactory price
