Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation, and more particularly to a rehabilitation training robot used for orthopedic rehabilitation training. Background Art

[0002] Orthopedic rehabilitation training is a key step in helping patients restore bone, joint, and muscle functions. Patients can use training robots to assist in rehabilitation training to improve safety during training. At the same time, with the help of training robots, the accuracy of posture during training is improved to ensure the precise docking and restoration of bones and joints, and prevent dislocation after recovery caused by incorrect posture training. In summary, the inventors have found that the existing rehabilitation training robots mainly have the following defects: when performing lower limb rehabilitation training, the current rehabilitation training robots only use the side panels of the intelligent rotating wheel machine and the sole fixing parts to fix the patient's feet, so that the thigh and calf sides are in contact with the side panels, and then the joint position is trained through the rotating wheel. As a result, during the training process, the hollow area of ​​the thigh and calf is too large and there is no superposition of any fixing force, which will cause instability during training. Subsequently, the stability during training will be reduced due to the influence of leg shaking, thereby reducing the intensity of rehabilitation training and increasing the discomfort of patients during training.
