Medical titanium alloy medical equipment is the third generation of surgical instruments after carbon steel and stainless steel. In order to improve the rust prevention performance, stainless steel instruments are often subjected to surface treatment such as chrome plating and electropolishing. However, chromium is toxic, and the detached chromium layer will have certain effects on the human body.

    The benefits of medical titanium alloys for medical devices are:

    1, The device is light, can reduce the damage to blood vessels, muscles and organs during the operation, reduce the fatigue of doctors, medical titanium instruments are more suitable for fine microsurgery;

    2, Good corrosion resistance and non-toxic, equipment does not rust, wounds are not easy to infect, wound healing is fast;

    3, Medical titanium alloy elasticity is appropriate, suitable for pliers, tweezers, micro scalpels and other equipment;

    4, When operating under a shadowless lamp, the reflective properties of medical titanium are weaker and more suitable than stainless steel.

    Medical titanium medical devices mainly include: scalpels, surgical forceps, surgical forceps, chest enlargers, suture needles, sutures, and the like. Medical titanium wire is used as a surgical suture, which has the advantages of small tissue reaction and good torsional resistance compared with other materials such as stainless steel wire. After suturing, the surgical wound is not easy to be inflamed, and the suture site of the bone is not easily displaced. The suture is generally made of medical titanium wire (TA1 or TA2 wire) having a diameter of 0.5 to 0.8 mm. In addition, the soft elasticity of the titanium-nickel alloy wire can promote the rapid healing of the wound.

    In addition, medical titanium alloys are also important materials for assisting rehabilitation equipment, such as wheelchairs, crutches, splints, and medical instruments.
