When the support is in specific operation, a patient firstly lies on a sickbed, when the support below needs to be used, legs needed to be rehabilitated by the patient are firstly placed on the support, at the moment, shanks of the patient are placed on the shank leg support and used as first contact points, and thighs of the patient are fixed through the thigh fixing lantern ring and used as second contact points. When passive rehabilitation is carried out on a patient on the brace, an operator holds the handle at the moment, the position of the limiting block is far away from the position of the sliding plate by rotating the adjusting rod with threads, the patient is accompanied by medical care personnel, strength is applied to the thigh part to carry out the leg stretching process, in the process, the lower leg supporting arm moves towards the oblique front, the auxiliary supporting arm moves downwards, the inner sleeve rod is retracted into the outer sleeve, the sliding plate moves forwards along the soft cushion layer through the roller structure, and at the moment, the lower leg support position adopts a hinging mode, so that the lower leg support always supports the lower leg part in the whole process; after the stretching is finished, the elastic supporting spring drives the shank supporting arm to rise under the driving of the elastic supporting spring, and under the condition of assisting force application of patients or assisting medical staff, the knee joint part is gradually reset to be in an initial bending state, so that the stretching and bending actions are finished. When the patient carries out active rehabilitation on the brace, medical personnel only need to hold the handle to screw in the adjusting rod, and when the limiting block props against the sliding plate, the sliding plate can not move forward, so that the linkage movement of each part of the brace is limited, and the patient only needs to use the thigh fixing lantern ring as a basic point of force application, and under the assistance of the medical personnel, the shank part can be lifted and put down along the knee joint through self strength.
When the upper rehabilitation support is adopted, firstly, medical staff fix leg fixing belts on thighs and shanks of patients respectively, then the bending degrees of knee joints of different patients are adapted by adjusting the distance between a first walking box and a third walking box on an L-shaped support, the lifting overall height of the legs of the patients is further adjusted by adjusting the retracting distance between a first telescopic arm and a second telescopic arm, the comfortable positions of the thighs and the shanks of the patients relative to the knee joints are finally adjusted, then the medical staff drive a driving shaft by starting a driving motor, drive a driving arm to move downwards by driving a tooth socket, thereby completing the main adjustment in a large range, then the patients cooperate with the electric power of an input electromagnet according to the self-independent strength when the knee joints are bent, and finally apply the acting force applied by external power on the knee joints through the repulsive force of a permanent magnet and the electromagnet, the patient can gradually and gradually train the self strength and the bending degree of the knee joint under the condition of maintaining the state of the adjusting position, so that the rehabilitation degree is gradually deepened, and the rehabilitation is finally realized. In order to realize the pressure fine adjustment of the pressing sheet at the knee joint position, the adjustment mode is processed except the repulsion type of the electromagnet and the permanent magnet, the pressing sheet can be realized through the left top spring and the right top spring, when the left top spring and the right top spring are adopted for adjustment, only medical personnel need to manually rotate and adjust the left positioning sleeve and the right positioning sleeve respectively along the left guide through hole and the right guide through hole according to the specific conditions of patients, the compression stroke adjustment of the left top spring and the right top spring can be realized through the self thread connection, thereby proper force can be applied to the knee joint of the patients, and the knee joint bearing capacity of the patients can be gradually and gradually exercised. The knee joint brace has the advantages of very high use and operation flexibility and very many matching effects, and can be adapted to patients with different conditions.
