      Titanium in medicine:   
      1、 Titanium has been used as a new material in the fields of pharmaceutical industry, surgical instruments and human implants in China and the rest of the world for several decades and has achieved great success.
      2、 Human body due to trauma caused bone, joint and spinal injury, can use titanium and titanium alloys manufactured artificial joints, bone plates and bone screws repair, is now widely used in clinical. It is also used in the hip joint (including femoral head), knee joint, elbow joint, metacarpophalangeal joint, interphalangeal joint, mandible, artificial vertebral body (spine orthosis), cardiac pacemaker housing, artificial heart Artificial dental implant, and titanium mesh in cranial plastic surgery and so on.
      3、 The requirements for implant materials can be grouped into three aspects: the biocompatibility of the material with the human body, the corrosion resistance of the material in the human environment, and the mechanical properties of the material.
