Background technique

Human skeletal tissue is a kind of hard tissue with a three-dimensional space structure. In the process of trauma or tumor treatment of patients, doctors are required to use metal fixation plates to fix the broken ends of the bones to complete the continuity of the bones.

Due to the individual differences of human bones and the human factors of doctors during the operation, the reduction of fractures and the truncation of bones are often not accurate enough, resulting in a certain gap between the effect after reduction and the doctor's expectations, and the accuracy of surgery and the therapeutic effect are not ideal. . Taking oral and maxillofacial surgery as an example, patients with jaw tumor resection or fractures need titanium metal or absorbable plates to complete the repair and reconstruction, but the reduction of fractures and the amputation of bones are usually completed by the surgeon with his own sensory judgment during the operation , there is a large human error, which will have a great impact on the reconstruction effect after fracture reduction and tumor resection. It is easy for doctors to rely on experience to operate with low accuracy of osteotomy angle, resulting in insufficient butt joint after bone grafting, which prolongs the recovery time of patients. surgery time.

Therefore it is necessary to design a kind of osteotomy guide plate, to overcome the above problems.
