Because tantalum is biocompatible, tantalum wires and tantalum foil have important medical applications. Human muscles grow on tantalum wire, so tantalum wire can be used to compensate muscle tissue and suture nerves and tendons. Tantalum wire can be used for oral sutures, visceral surgical sutures. Tantalum rods and tantalum plates can also be processed into medical devices such as stents and bone pins. Tantalum sheets can be made into artificial ears, fixed behind the head, and then moved straight to the skin. After a period of time, the new skin graft grew so well that it was hardly noticeable that the ears were made of tantalum sheets.
Niobium also plays an important role in surgery. Niobium rods, niobium plates and niobium foil can be used to make medical devices. Niobium has a good "biological adaptability material". Niobium wire has excellent corrosion resistance and will not act on various liquid substances in the human body, so it can be combined with organic tissue for a long time and remain harmlessly in the human body.
In the medical industry, titanium is an emerging material. Titanium rods, titanium plates and titanium foil can be processed into surgical instruments, human implants and other fields. Now titanium has achieved great success in the medical field.Titanium and titanium alloys can be used to manufacture artificial joints, bone plates and titanium alloy screws. Titanium and titanium alloys are processed into hip joints (including femoral head), knee joints, elbow joints, etc. In stomatology, titanium alloys are also used for artificial dental implants.
One of the most notable properties of zirconium is its resistance to corrosion. Zirconium rod and zirconium plate has very good corrosion resistance and it is often used in the field of neurosurgery. Zirconium alloy is a good material for surgical instruments. Zirconium wire and zirconium foil is sometimes used for sutures during brain surgery.
The most obvious feature of superelastic (SE) Nitinol rod is that its flexibility is 10-20 times that of stainless steel rod.
In other words, one can observe the equipment "bouncing back" at up to 11% strain. The Nitinol stent is self-expanding. They are shaped as open structures.
Nitinol is compressed into the catheter, which is then pushed out and expanded against the wall of the blood vessel. Nitinol guides/Nitinol wire have played an important role in the success of angioplastic medicine.
Nitinol wire has excellent biocompatibility.
