Tantalum products and their applications

Tantalum wire
Tantalum can be made into filaments with a diameter of 0.2mm, which can be used in clinical operations as tension-resistant sutures that are easy to sterilize and less irritate surrounding tissues.

Tantalum sheet
When the upper and lower extremities or other parts have cracked fractures or fracture nonunion, tantalum metal can be made into tantalum sheets of different shapes and sizes to repair the cracks and nonunion in order to achieve functional healing.

Tantalum bracket
Due to the strong ductility of tantalum metal, the diameter of the tantalum wire made of it can better adapt to its fluctuation in the artery and achieve accurate and rapid release. Some scholars used the coronary arteries of minipigs as a research model, implanted tantalum wire stents made of tantalum metal into the body, and observed for a period of 6 months. They found that there was no rejection in the local tissues of the coronary arteries after the stents were implanted. , and the neointimal proliferation changes in phases.

Porous tantalum joint
Porous tantalum has obvious advantages in the use of joint materials. Because tantalum metal has certain elasticity, when it interacts with cortical bone, it can produce slight deformation without fragmentation. In addition, the friction coefficient of tantalum metal is higher than that of other materials. The metal is high, so the stability of tantalum metal is relatively high after implantation.

Tantalum coated products
Many metal materials can be used in the medical field due to their unique properties, but their advantages cannot be used clinically due to their lack of biocompatibility. Now, we can coat the surface of these metal materials with highly corrosion-resistant and stable tantalum metal, so that those metal materials that have unique properties but were originally prevented from being clinically used due to low biocompatibility can be reused in clinical practice.
