Application of tantalum rod in medical field

Titanium is the most commonly used treatment for patients with femoral head necrosis. At present, a team has developed 3D printed bionic bone trabecular porous tantalum metal stent, which is the result of the national key research and development plan "Clinical application research and promotion of 3D printed personalized implant devices".

Compared with titanium, tantalum has better biocompatibility and human body is not prone to rejection. Moreover, the elastic modulus of tantalum is closer to bone tissue, which is more suitable for the bone trabecular structure of bionic human body. The growth rate of bone tissue is much higher than that of titanium metal, which can promote bone cells to grow into the pores of tantalum rods quickly.

However, at present, the few companies in the world that make such materials manufacture "uniform" cylindrical tantalum rods, whose regular "honeycomb" pore structure is not very suitable for the trabecular structure of human bone. To this end, the team, together with the team of the State Key Laboratory of Powder Metallurgy of the University, jointly developed domestic tantalum metal powder materials, and through more than a year of repeated design and 3D printing, customized a "tantalum rod" for patients.

After 3D printing the tantalum rod with bionic bone trabecular structure, how to speed up the growth rate of bone tissue? The team innovates with a "bionic" approach. Using the "biophile" characteristics of tantalum metal, the "seed" is planted in the tantalum rod, and the bone tissue can grow on the internal and external prosthesis surface at the same time, and finally achieve the complete integration of the porous tantalum metal rod and the human body.

Fortu Tech can produce and process tantalum powder, tantalum rod, tantalum plate, tantalum tube, tantalum foil, tantalum wire and tantalum processing workpiece.
