Lower limb rehabilitation robot

Abstract

The invention provides a lower limb rehabilitation robot. The robot comprises a rack, a lifting weight reduction mechanism, a mechanical leg moving mechanism, a mechanical leg movement mechanism, a treadmill and a treadmill lifting mechanism; the rack comprises a rack bottom frame, supporting columns arranged at one end of the rack, supporting crossbars disposed between the supporting columns, anda supporting vertical rod disposed in the middle of the supporting crossbars, wherein the bottom of the supporting vertical rod is fixed to a horizontal frame of the rack bottom frame; the treadmillis disposed in the rack bottom frame; the treadmill lifting mechanism is arranged on a bottom plate of the treadmill; the lifting weight reduction mechanism is arranged on the sides of the supportingcolumns; the mechanical leg moving mechanism is arranged on the side of the middle supporting crossbar, and the two ends of the lifting weight reduction mechanism are fixed to the supporting columns;the mechanical leg movement mechanism is arranged on a mechanical leg mounting plate of the mechanical leg moving mechanism. The robot can effectively adjust the leg length of mechanical legs and canbe adjusted according to the body width of a patient to make gait simulation more accurate, the structure is safe and small, and the overall height is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation equipment, and in particular relates to a lower limb rehabilitation robot. Background technique [0002] Rehabilitation therapy is a new therapeutic discipline that promotes the recovery of the physical and mental functions of the injured and disabled, and it is also a new technical specialty. Its purpose is to enable people to restore the ability of daily life, study, work and labor, and social life as much as possible, integrate into society, and improve the quality of life. [0003] In traditional rehabilitation training, a number of professional medical staff assist patients to complete leg and torso exercises. Or massage the diseased joints or muscles of the paraplegia patient by the nursing staff, that is, one-to-one rehabilitation treatment. The medical staff not only has high labor intensity and high cost, but also it is difficult to ensure stable and continuous exercise tr...

The patent application number is 201210225997.1 for the invention patent "sitting and lying lower limb rehabilitation robot", including seat, mechanical arm, main industrial control box, human-computer interaction interface, electric stimulation hand-held switch and electrode sheet, electromyographic signal acquisition electrode sheet, function The industrial control box for sexual stimulation and myoelectric signal acquisition is a kind of rehabilitation training by placing the patient on a specific seat and driving the lower limbs by the mechanical arm on the seat, but it cannot realize standing training and lacks waist activity devices. Greater burden on the waist during training

The patent application No. 201510311272.8 is an invention patent "a walking aid lower limb of an exoskeleton robot". and wearing comfort, but there is only one knee joint and it is mainly used for walking, and it cannot coordinate the rehabilitation of the entire lower limbs

[0004] At present, the structure of lower limb rehabilitation training robots is relatively simple, and the existing lower limb rehabilitation training robots require patients to stand upright by their own strength, but for patients in different rehabilitation stages, especially those in the early stage of rehabilitation, it is difficult to control their own vertical posture. Standing balance is easy to fall and cause secondary injury; the coordination of waist and lower limbs is not enough during rehabilitation training, and it is impossible to achieve comprehensive rehabilitation of lower limbs
