Safety manipulator for rehabilitation training robot for upper limb

Abstract

The invention relates to a safety manipulator for a rehabilitation training robot for an upper limb. The safety manipulator comprises a manipulator body, a support device, a binding device, a grip device, support plates, rotating devices, horizontal movement chambers, a retractable grip and a linkage hand, wherein the front end of a supporting plate is fixedly connected with the grip device; the three support plates are arranged in the middle of the supporting plate, and are rotationally connected through the rotating devices; and the horizontal movement chambers are formed in the front support plate and the rear support plate. The length setting of each part of the mechanical arm is achieved through the multi-step telescoping of an automatic telescopic column provided by the invention, and precise adjustment ensures the safety training effect of a patient, so that the real needs of the patient are better met; the rotation lifting and the horizontal movement of the multiple joints achieve the training of the whole arm; and the connection between a crossbar and a sliding rod can limit the range of rotation and horizontal movement, so that the training safety and comfort are ensuredfor the patient; the grip device is designed to be retractable, and the design of a soft cotton material inner core and a finger chamber are more in line with the actual needs of the patient.

Description

technical field [0001] The invention relates to a manipulator of a rehabilitation robot, in particular to a safety manipulator of a robot for rehabilitation training of upper limbs. Background technique [0002] Rehabilitation training robots are mainly used in sports therapy, such as preventing low motor performance and contracture of limbs, allowing joints to move within the range of motion, strengthening muscle strength, enhancing endurance, coordination, walking training, gymnastics treatment, etc., if The robot is equipped with an instrument with the function of measuring rehabilitation, which can quantitatively collect the data during the recovery process of the training object's function, and make a decision on the recovery process; pre-analyze and evaluate, and record the whole process of rehabilitation. Rehabilitation data may produce some positive feedback effect. Research on rehabilitation training robots includes two aspects: upper limb rehabilitation training ro...

AI Technical Summary

Problems solved by technology

[0003] The upper limb rehabilitation equipment currently used has a single product structure and function, and its application range is limited to local joints, that is, the rehabilitation of the wrist joint, elbow joint and shoulder joint is completed by a separate device, and there is no such device that can realize the rehabilitation of each joint of the entire arm. Integrated products, that is, incomplete, and most of them are electromechanical, just repeat the set movement, and do not consider the patient's feelings, resulting in a certain unsafe product for the patient, even if the patient feels pain. When moving, it will still continue to carry out its original set activities, which will easily aggravate the patient's injury, and when the patient's hand can move slightly and can perform reciprocating activities, such a rehabilitation device cannot sense it, and just repeats the original The movement of the patient will cause the patient to lose autonomy, not every important joint is moving, especially the movement of the hand, and the hand joints are more and more flexible, so it is essential to restore the hand, but most of the fingers Rehabilitation equipment ignores this point, and there is a lack of devices for thumb rehabilitation. This kind of existing equipment that does not fit the patient's real training intensity and patient feelings, and ignores the multi-faceted training of the patient's fingers, that is, the lack of safety limits and comprehensiveness of training. As a result, patients cannot really get the real effect of training, and it may lead to further training deterioration over time, etc.
