[0029] During operation, the auxiliary frame is pushed to a suitable position on one side of the bed. The support rod is removed from the holder and rotated to align with the ground. The auxiliary positioning rod is rotated from the mounting slot to align with the support rod and secured with a pin. After disinfecting the patient's lower leg or heel, it is placed on the surface-disinfected quick-release clamp and secured. The support is then raised to a suitable height using the lifting assembly to perform disinfection of the entire leg. For ease of operation, a disposable disinfectant film can also be laid on the surface of the quick-release clamp; these are all readily apparent to those skilled in the art. For patients with leg fractures requiring support in two areas, two auxiliary frames can be combined to form a suspension system, which, in conjunction with a single auxiliary frame for support, can significantly reduce the workload of doctors, improve disinfection convenience, and shorten disinfection time.
