Tantalum wire
Tantalum wire can be used as a tension-resistant suture in clinical surgery. It has the advantages of easy sterilization and little stimulation to surrounding tissues. Xu Hao and other researchers used tantalum wire to perform cerclage internal fixation surgery on 33 patients with patellar fractures. Among them, 31 cases recovered well, only 2 cases developed mild arthritis, and there were no obvious complications 5 months to 16 years after surgery .
Tantalum sheet/block
Using 3D printing to customize tantalum patches, it can be used as a repair to achieve functional healing when fractures occur or fractures do not heal. The application of tantalum blocks/sheets is not only in common orthopedic surgeries such as upper and lower limbs, pelvic acetabulum (such as Lidakang customized tantalum patches), but also in various surgeries such as artificial tantalum ears.
Tantalum stent
The excellent ductility of tantalum metal makes it a reliable choice for arterial stents. It has been proven to be safe and effective in both animal experiments and clinical trials. In the past clinical trials on patients with ischemic syndrome, tantalum wire stents were not only easy to operate and effective, but also greatly reduced the probability of subacute thrombosis and vascular restenosis after 6 months.
Tantalum rods/tantalum-coated femoral stems/tantalum acetabulum/tantalum total knee (porous tantalum)
They are different from the pure tantalum products mentioned above. They are made of porous tantalum after surface modification using advanced preparation technologies such as vapor deposition/vapor deposition. This technology can transform tantalum into metal trabeculae with a honeycomb-like three-dimensional structure. The 75%-80% pores and the average pore size of about 430μm provide space and microcirculation metabolic environment for osteoblasts, induce bone ingrowth, and form a strong bone-metal bond.
The elastic modulus between cancellous bone and cortical bone (about 3Gpa) can effectively avoid the stress shielding effect and achieve long-term retention in the human body without side effects.
In addition, porous tantalum has the characteristics of promoting cell proliferation and improving the bone-forming ability of osteoblasts. Tantalum support rods are mainly used to treat femoral head necrosis, while tantalum coatings are mainly used in femoral stems, both of which take advantage of the good biocompatibility, strong toughness and inertness of tantalum metal.
