Description

Complete gait running gear of three joints
Technical Field
The invention relates to the field of rehabilitation robots, in particular to a three-joint complete gait walking device.
Background
The gait walking rehabilitation robot is a new application of combining a robot and rehabilitation medical treatment, and the rehabilitation robot can provide active and passive rehabilitation training for patients with lower limb paralysis by combining different robot control methods. Under the background that the aging of the population of China is continuously intensified, the application of the rehabilitation robot can relieve the heavy work of a rehabilitation physical therapist in the traditional rehabilitation therapy, more importantly, the rehabilitation robot can provide the rehabilitation therapy at any time and any place according to the will of a patient, the therapy process can be monitored and recorded in real time, and then the rehabilitation therapy can be continuously improved after the data are analyzed. Under the background of the aggravation of aging in China and the strong demand of people on high-level medical services, the gait walking rehabilitation robot has a very good application prospect in the field of rehabilitation medical treatment.
According to related data, the stroke is a big killer for depriving the old of life and influencing normal life. Among them, the prominent hemiplegia affects the normal walking and self-care ability of the elderly. How to effectively enable the groups to realize the walking ability again, and the realization of the correct gait posture is a great clinical problem at present, and the gait walking rehabilitation robot realizes the possibility. The device effectively helps the rehabilitation personnel to find the correct walking posture and helps the rehabilitation personnel to carry out the neural reconstruction of the gait function, and greatly meets the requirements of the rehabilitation personnel and the clinical requirements. Most gait rehabilitation robots in the market at present are common weight reduction and treadmill matched mechanical motions or upgraded versions of lower limb active and passive training, the intelligent level is low, only a single (active and passive) training mode can be realized, and the intelligent effective training and evaluation means is lacked. In clinical practice, it is known that the whole gait process of human body is realized by the linkage relationship of three joints, namely hip joint, knee joint and ankle joint. However, most of the robots in the market have only two joints without ankle joint training in motion (hip joint and knee joint), and are only in simple correlated motion, so that the functions are not complete. For rehabilitation personnel who need to recover gait walking, a correct gait walking posture and a better training mode are of the utmost importance.
