The current operation is to clamp the bone plates by clamping forceps. The structure of the clamping forceps is relatively common. The basic principle The clamping is realized by a torsion spring and a pair of mutually hinged clamping rods. After an orthopedic patient has undergone a fracture operation, a fracture fixing device is required to protect the fracture of the orthopedic patient.

The existing fixation devices for fractures are all fixed, and the clamping width of the fixation device for fractures cannot be adjusted. Due to the difference in fat and thinness of patients, the fatter and thinner patients have a fixed effect on the fracture during use. Poor, even with obese patients, it cannot be used during fixation. Since the existing fixing device cannot change the clamping width of the clamping device, it is inconvenient for the user to use, and the existing fixing device for fractures is reduced. Therefore, we propose an orthopedic clinical multi-purpose clamping device to solve the above problems.
