Zhenghai Bioscience announced that the company recently obtained a "Medical Device Change Registration Certificate" issued by the National Medical Products Administration, completing changes to the specifications and product technical requirements of "Active Bone Biomaterial". The changes include adding product specifications and modifying related content of product technical requirements. The change certificate can be used together with the original registration certificate, which meets the company's development needs, satisfies customer demands, and facilitates business expansion, but has no significant impact on recent operations.
