At present, digital biotechnology is rapidly developed and widely introduced in surgical clinics. Among them, the techniques that can accurately convert preoperative designs into intraoperative operations include surgical navigation and guide plates. The operation navigation needs to register the information of CT, MRI and the like before or during the operation with the patient entity through a large-scale and expensive navigator, and not only the operation is complex, but also the navigation fails. The surgical guide plate technology has a certain application in orthopedics, plastic surgery and maxillofacial surgery, the used data mostly come from CT or three-dimensional scanning, the requirement on equipment is high, the guide plate design process is also complex, and the guide plate can be molded only by operating special engineering technicians.
There are many methods for mandible restoration reconstruction, but the most common and most effective method is autologous bone grafting, and after some osteotomy is performed on a human body, the bone is usually taken from the ilium and then implanted into the resected part after molding.
In order to achieve the purpose of accurately repairing the damaged mandible by the ilium and reconstructing the normal form of the mandible, the surgical guide plate technology is widely applied to the auxiliary operation process. The invention discloses a bone flap guiding plate for a jaw bone transplantation operation, which is characterized in that a bone flap is arranged on the bone flap, a bone surface is arranged on the guiding plate, and a small gap is reserved between the guiding plate and the bone surface. Clinical research proves that muscle tissue in bone transplantation can not only rebuild blood circulation of transplanted bone tissue, but also bring osteoblasts and bone-induced multiple growth factors into the muscle tissue, promote formation of new bone, accelerate bone tissue repair, reduce compression and torsion of muscle pedicle in the bone transplantation process, protect good blood circulation of bone flap, and lay a solid foundation for healing of postoperative bone flap. How to ensure the guiding of the transplanted bone to be in place and fully utilize the benefits of soft tissues such as muscles and the like brought by bone flaps on a human body does not have a disclosed technical scheme at present.
