Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a composite medical bone crusher required for bone transplantation and its application. Background technique [0002] Bone graft materials are mainly used in orthopedic surgery for bone fracture repair, coating of bone implants, artificial joint repair, injectable bone graft materials for osteoporosis and other indications, and in spinal treatment for posterior spinal fusion, etc. All kinds of vertebral defect indications, mainly used in dental extraction trauma and maxillofacial surgery and other indications. Bone graft materials usually contain one or more functional components, such as an osteoconductive matrix, which provides a scaffold for new bone growth, osteoinductive proteins, and induces stem cells to differentiate into osteoblasts, which generate new bone tissue under appropriate conditions. The role of bone graft is mainly to provide support, fill the bon...
