Description

Passive restorer for upper limb joints Technical Field The invention relates to the technical field of joint passive restorations, in particular to an upper limb joint passive restorative. Background The upper limb joint dysfunction is common symptoms of diseases such as osteoarthritis and the like and after long-term braking, the common symptoms are manifested by joint pain, limited movement and stiffness, the quality of life of patients is influenced, in clinical rehabilitation, the joint loosening technology is a core means for treating the disorder, joint movement can be recovered, pain is relieved, and the mobility is improved, but the clinical application and teaching training of the technology depend on manual operation, the limitation exists, on one hand, the treatment effect is difficult to quantify and standardize, the manual operation is based on personal experience and hand feeling, key parameters cannot be accurately measured and reappeared, on the other hand, the teaching link is low in efficiency, students are difficult to feel operation difference, understand classification technology, the examination depends on naked eye observation and experience, the existing upper limb joint rehabilitation equipment in the market is single in movement mode, and the bionic simulation of the essence of the joint loosening technology is lacking, and the gap is provided with the traditional manual treatment. Therefore, intelligent upper limb joint loosening equipment is urgently needed in the rehabilitation medicine field, joint loosening operation principle and integrated sensing technology are fused, accurate quantification, personalized adaptation and standardization teaching of treatment parameters are realized, and the manpower and technical bottlenecks are broken through. In the clinical rehabilitation field, the upper limb joint dysfunction is common complications of orthopaedics postoperative patients with chronic musculoskeletal diseases and long-term braking, the patients often accompany problems of joint stiffness, limited movement range, muscle adhesion and the like, daily life and limb function recovery are seriously affected, medical research proves that continuous mild passive movements can be developed in early stage after joint injury, the degree of joint movement can be effectively maintained, local blood circulation is promoted, soft tissue adhesion is reduced, a foundation is laid for follow-up active rehabilitation training, along with the development of rehabilitation medicine, the clinical requirements on standardized and accurate passive rehabilitation equipment are increasingly highlighted, the upper limb joint structure is complex, the joint movement tracks of shoulders, elbows, wrists and the like are different, individual differences exist in different patients in the degree of injury and rehabilitation stage, diversified passive movement parameters are required to be adapted, and on the basis of clinical and teaching requirements, and the medical principle of joint movement technology is combined, the core aim is to provide safe and controllable passive rehabilitation support for the patients, and the patient efficiently recovers the joint movement track, so that a passive rehabilitation aid is provided for the patients. Through retrieval, patent publication number CN112022634A discloses a three-degree-of-freedom horizontal multi-joint upper limb rehabilitation training robot, in which the upper limb forearms and hands of a patient are fixed on arm supports and tail end handles of the robot, and the robot arm drives the tail end of the upper limb of a human body so as to drive the upper limb to complete various rehabilitation training modes in the horizontal plane and sagittal plane of the human body. The device is driven by three motors, the first joint motor drives the large arm to swing relative to the upright post, the second joint motor drives the small arm to swing relative to the large arm, and the third joint motor drives the screw rod to drive the tail end of the robot to do vertical linear motion. The posture, the movable range and the training intensity of the upper limbs of the human body are accurately controlled by adopting a servo closed-loop control system. The human-computer interface consists of a touch screen and a switch button, a rehabilitation training mode can be selected through the touch screen, the rehabilitation training modes are displayed in a corresponding dynamic schematic mode, the human-computer interface is convenient and easy to understand, and the speed and time of each rehabilitation training mode and the moving range of each joint can be adjusted according to the condition of a patient. The prior art has the following defects in the using process: The passive restorer of the upper limb joint in the prior art has single function, can only meet the requirement of passive exercise of the joint and physiological motion of a user in the three-axis
