Application of titanium rods in medical treatment With the development of titanium industry, more and more fields are finding applications for titanium products.And the titanium rod is one of the best. (1) Titanium rod for medical use Titanium, as an emerging material, has been used for decades in the global rmaceutical industry, surgical instruments, human implants and other medical fields, and has achieved great success. (2) the human body should be caused by trauma, tumor bone, joint injury, the use of titanium and titanium alloy can be made of artificial joints, bone plate and screws has been widely used in clinical.It is also used in hip joint (including femoral head), knee joint, elbow joint, metacarpolangeal joint, interlangeal joint, mandible, artificial vertebrae (spinal orthoses), pacemaker shell, artificial heart (heart valves), artificial dental implants, and titanium mesh in skull plastic and so on. (3) The material requirements of titanium rod implants for medical use can be classified into three aspects: the biocompatibility of the material with human body, the corrosion resistance of the material in human environment and the mechanical properties of the material.
