“Thanks to Tang Du Hospital for my concern and care, and superb medical skills have given me no worries!” Wang Xiaowei, a soldier of the armed police stationed in Tibet who had the Nutcracker syndrome, received the left renal vein at the Fourth Military Medical University Tangdu Hospital. 3D printing titanium alloy extravascular stent implantation was discharged after surgery. This is another vivid example of the achievements of the new scientific research achievements of the Institute.


After checking with Xiao Wang in detail, Associate Professor Zhang Bo, who was consulted, decided to use the 3D titanium alloy extravascular stent implantation in the left renal vein first created by the hospital to relieve him of pain. Last month, under the guidance of the director of the Department of Urology, Wang Bo, Associate Professor Zhang Bo used laparoscope to implant titanium stents tailored for Xiao Wang based on 3D printing technology into his body, propped up a life channel. One week after surgery, all symptoms related to Xiao Wang disappeared, and only four small scars less than 1 cm were left in the abdomen.


Titanium alloy biomedical materials are used to make titanium alloy implanted in medical devices, prostheses or artificial organs and auxiliary treatment devices in human bodies. There are mainly titanium 6 aluminum 4 vanadium, titanium 5 aluminum 2.5 tin and other alloys. They have high specific strength, mechanical properties close to human bones, and strength far better than that of pure titanium. They also have characteristics such as fatigue resistance, corrosion resistance, and excellent biocompatibility.

There are mainly ti-6-al-4-v, ti-5-al-2.5tin, ELI ti-6-al-4-va and other alloys. They have high secific strength, mechanical properties close to human bones, and strength far better than that of pure titanium. They also have characteristics such as fatigue resistance, corrosion resistance, and excellent biocompatibility.


Widely used in various artificial joint artificial bone, bone fixation devices, artificial teeth, dental inserts, fixed bridges and so on.
