Biopatch is extracted from natural organisms by various techniques, and then implanted into the human body according to some molecular biology and immunology principles, which can play a certain cellular scaffolding role, fill the missing tissues in damaged areas, and induce the body’s own repair function, so that new tissues can gradually grow and complete the process of organ tissue regeneration. Biopatch is used in neurosurgery for meningeal repair, repair of esophageal cancer after resection, and cranial repair, as well as in cosmetic surgery, large burns, gynecology and oncology. Biopatch has high biocompatibility, low probability of rejection, and is relatively safe, does not cause malignant or teratogenic effects, and is relatively stable and quick to recover.
