By rotating the connecting bolt, the lower clamp and the upper clamp clamp the bone structure at one end of the patient, and after fixing, the lower clamp and the upper clamp are fixed by tightening the connecting bolt, which solves the problem that the doctor needs to continuously clamp the upper clamp and the lower clamp during fracture reduction surgery. The first method requires a dedicated person to fix the device, which wastes manpower. The upper clamp and the lower clamp can be fixed by tightening the connecting bolts after the upper clamp and the lower clamp clamp the bone structure at one end of the patient, which greatly enhances the usability of the device. By spraying cleaning liquid on the inner walls of the upper clamp and the lower clamp, and then rotating the drive shaft seat to make the cleaning roller fit with the inner wall of the upper clamp, the inner walls of the upper clamp and the lower clamp can be cleaned and disinfected by rotating the handle after fitting, which solves the problem of residual impurities on the inner walls of the upper clamp and the lower clamp after the device operation affecting the reuse, and achieves the effect of spraying disinfectant on the inner walls of the upper clamp and the lower clamp after the operation, and then rotating the handle to clean and disinfect the inner walls of the upper clamp and the lower clamp, which greatly enhances the cleanliness of the equipment.

[0028] How this utility works:

[0029] During use, the lower clamping plate 11 is moved upward by rotating the fixing bolt 10, so that the upper clamping plate 9 and the lower clamping plate 11 clamp the operating bed guardrail or bed board to fix the device. After fixation, the angle of the device can be adjusted by rotating the fixing shaft 4 and the semi-threaded bolt 2. After adjustment to a suitable position, the limiting rod 6 is pulled out to make the limiting block 5 fall downward into the groove, so that the fixing shaft 4 cannot rotate. At the same time, the semi-threaded bolt 2 is tightened to prevent the semi-threaded bolt 2 from rotating, so that the device is fixed, which solves the problem of the doctor having to use one hand to hold the device to fix the patient's bone structure and the other hand to fix the patient's bone structure when performing fracture reduction at the patient's ankle position. The problem that this method is inconvenient for doctors to perform surgery on patients is solved. The angle of the device can be adjusted in multiple directions before the device is fixed on the operating table guardrail or bed board before the patient is operated on, which greatly enhances the doctor's surgical efficiency. By fitting one side of the support plate 15 with the patient's heel, the protective pad 16 is used to avoid damage to the patient's heel when the device is fixed. The telescopic spring rod 14 passes through different connecting holes, and the length of the right telescopic rod 13 can be adjusted, which solves the problem that the existing device cannot perform fracture reduction surgery and needs to place the bone structures at both ends of the patient in a suitable position and then fix them. The device can be placed in a suitable position before the device is fixed. After being fixed on the operating table guardrail or bed board and fixing one end of the patient's bone structure, the effect of fixing the patient's heel by adjusting the length of the right telescopic rod 13 greatly enhances the doctor's surgical efficiency. By rotating the connecting bolt 18, the lower clamp 1 and the upper clamp 20 clamp and fix the bone structure at one end of the patient. After fixation, the lower clamp 1 and the upper clamp 20 are fixed by tightening the connecting bolt 18, which solves the problem that the doctor needs to continuously clamp the upper clamp 1 and the lower clamp 20 during fracture reduction surgery, and this method requires a dedicated person to fix the device and wastes manpower. The upper clamp 20 can be fixed by tightening the connecting bolt 18 after the upper clamp 20 and the lower clamp 1 clamp the bone structure at one end of the patient. The fixing effect of the upper clamp 20 and the lower clamp 1 greatly enhances the usability of the device. After the operation, cleaning liquid is sprayed on the inner walls of the upper clamp 20 and the lower clamp 1, and then the cleaning roller 24 is fitted with the inner wall of the upper clamp 20 by rotating the drive shaft seat 21. After fitting, the inner walls of the upper clamp 20 and the lower clamp 1 can be cleaned and disinfected by rotating the handle 23, which solves the problem of residual impurities on the inner walls of the upper clamp 20 and the lower clamp 1 after the operation and affects the reuse of the device. After the operation, the inner walls of the upper clamp 20 and the lower clamp 1 can be sprayed with disinfectant, and the inner walls of the upper clamp 20 and the lower clamp 1 can be cleaned and disinfected by rotating the handle 23, which greatly enhances the cleanliness of the equipment.
