Advantages of Nitinol stent in the treatment of tracheal stenosis
Nitinol tube has excellent biocompatibility, wear resistance and corrosion resistance, better than stainless steel. Nitinol is an ideal biomaterial with little irritation to gas pipe walls. However, Nitinol stents, like other tracheal stents, still exhibit local chronic inflammation due to foreign body irritation and normal tracheal epithelium to discuss reconstruction issues.
Nitinol alloy is a new type of support material with high added value. At the same time, Nitinol will play an increasingly important role in medical equipment. Iron and steel enterprises with relevant technical reserves should intervene as soon as possible to obtain good earnings.
In order to realize the welding between the micro-needle pipe and 304 stainless steel, the micro-needle pipe is 1.8mm * 1.4mm. Stainless steel is 2.5mm * 1.8mm. During the welding process, insert the spined tube into the stainless steel tube to a depth of 4mm. Because of its small size, I went outside to look for some laser welders, but they could not be welded, because the niti tube was brittle in heat and easily broke.
