At this time, the patient's thigh Squeeze the splint so that the splint exerts a squeeze on the spring, and under the action of the spring’s resilience, the splint exerts an anti-extrusion force on the patient’s thigh, so that the patient’s thigh is firmly connected to the support seat. The medical personnel then repeatedly press the airbag with their hands. At this time, the inflated gas formed by the airbag is discharged into the air cushion through the intake pipe, so as to inflate the air cushion. Through the expansion of the air cushion, the air cushion exerts a soft clamping force on the patient's calf. Its purpose is to make the connection between the connecting sleeve and the patient's calf stable. When the degree of inflation of the air cushion meets the needs of the medical staff, the medical staff will stop using the air bag. Open the connecting plate, and the medical personnel turn on the first switch by hand, through the first switch, the motor drives the rotating shaft to drive the gear to rotate clockwise, and through the meshing effect of the gear and the ring rack, the gear drives the connecting sleeve together with the patient Rotate the calf of the patient clockwise, that is, let the patient's foot rotate along the inner side. When the inner side of the patient's foot rotates too much, the medical staff will turn off the first switch by hand, and then turn on the second switch by hand. The second switch makes the motor drive the rotating shaft to drive the gear to rotate counterclockwise. Through the meshing effect of the gear and the ring rack, the gear drives the connecting sleeve and the patient's calf to rotate counterclockwise, that is, the patient's foot moves along the Rotate in the lateral direction until the patient's feet together with the calf and knee joint are at the same level as the patient's thigh, the medical staff closes the second switch by hand to stop the motor. The motor has a self-locking function. At this time, the patient The horizontal state of the knee joint and thigh is fixed. Through the above methods, the levelness between the patient's knee joint and thigh is adjusted and corrected. The medical staff can then perform knee joint replacement surgery on the patient. The joint replacement is adjusted and corrected. The device is ingenious in structure, powerful in function, and easy to operate. By using this device, it eliminates the need for a medical staff to fix the patient's knee joint and thigh level by hand, so that the patient's knee joint and thigh level can be adjusted. The state is fixed, which effectively reduces the manpower of the medical staff. At the same time, after the device is used, the medical staff first opens the regulating valve by hand, so that the inflation gas in the air cushion is discharged from the exhaust pipe to the outside, that is, the impact of the air cushion on the patient's calf. When the soft clamping force disappears, the medical staff can remove the device from the patient's leg. The battery is used to provide energy for the motor. The motor is a low-speed motor whose model is preferably 4632WG370. The airbag is for medical use PVC airbag, the installation groove is the installation carrier of the ring rack, and the connecting plate is to connect the support seat and the connecting sleeve as a whole.
