Problems solved by technology

[0002] Fracture is a common disease in orthopedic clinics. After a fracture occurs, the fracture site is usually reset first, and then the fracture site is fixed with screws and plates. After the fracture site is healed, the screw is screwed out of the patient's bone and Plate removal; the existing orthopedic broken nail removal device has a single structure and is usually manually operated by a doctor. There are no good fixation and limit measures for the patient's treatment site, and it is easy to cause secondary damage to the patient's treatment site during the nail removal process. Is not conducive to the recovery of patients; therefore, it is necessary to improve the existing technology
