Titanium metal in mecical

The main advantages of titanium alloy is excellent rust resistance, belongs to the ecological metal, contact with the human body for a long time will not produce allergic and immune response, so a lot of prosthetic joint adopt titanium alloy.
Stems mainly from the following features in the aspect of cutting tool titanium cn applications, feel is gentle, is not so cold steel, and aluminum, but are more hardwearing than aluminum alloy high hardness.So often referred to as high-grade the handle material.
Blade with titanium alloy is not much, because, though lighter than steel alloy, titanium alloy but can only be reached around HRC46 hardness, not universal cutting hardness standard, only occasionally used in diving knife, purpose is water rust resistance.
The application of titanium in surgical operation, is also very fascinating.At present, the surgical osteosynthesis is stainless steel, using stainless steel has a fault, is the bone healing, the stainless steel piece out again, this is a very painful thing.Otherwise, the stainless steel will rust and cause harm to human body.If use titanium material of artificial bone will make the orthopaedic technology completely changed.At the head of the damage, using titanium plate with titanium screws, after several months, bones will grow back in titanium plate holes and screw, new muscle fibers are wrapped in titanium sheet, titanium skeleton like a real bones and flesh of support and reinforcement effect, so, titanium has been hailed as "metal".Now it is already applied to the joints of the knee joint, shoulder joint, rib, skull, active heart valve, bone clamp, etc.
The current human use of the four series of hydrogen storage in metal, titanium is one kind of, also is a kind of cheaper, but now have not found a more ideal human "hydrogen storage metal", once the problem solved, people can use hydrogen as fuel
Is titanium is finding wider and wider application in medical apparatus and instruments, the early main used to make some small blood vessels of suture with needle, electrocardiogram electrode materials and ophthalmic instruments. In recent years has been used as a retractor heart and heart plug, which is used in the process of cardiac surgery assisted medical devices, it requires high strength, corrosion resistance, non-toxic, easy to clean. Heart plug generally according to the diameter of the plug size is divided into six types: 20, 18 ~ 17 ~ 19 mm, 16 mm to 15 mm, 14, 12 ~ 13 mm ~ 11 mm and 10 ~ 9 mm. The heart, jun is divided into large and small two kinds. Large stem thick phi 12 mm, small stem thick phi 10 mm. Large jun 24 mm wide

Pure titanium porcelain teeth is a kind of precious metal porcelain teeth, titanium has steady chemical property and excellent biocompatibility, not to any reaction with human tissue.Don't cause gum inflammation, neck edge black, dental metallic odor and other problems.Pure titanium nonmagnetic, can through X-ray, does not affect the nuclear magnetic resonance, X-ray films, CT, etc., does not affect the medical examination in the future.Light weight, less than 1/6 of the other PFM alloy.
