As three categories of orthopaedic implant medical devices, biological evaluation is the most authoritative and effective way to verify the safety of products. The company's '3D printing absorbable orthopedic implants' products entrust Sichuan Biomedical Device Testing Center to conduct all ten biocompatibility tests.

On August 19, 2021, the product has obtained eight biocompatibility test reports, and the remaining two tests of sub chronic toxicity and bone implantation are expected to obtain all biocompatibility test reports next year.
