A lower limb rehabilitation training device

Abstract

The invention discloses a rehabilitation trainer for lower limbs. The linkage can be realized in such a way that thigh rods and shank rods are effectively connected by setting a driving component, wherein a drive rod can be driven to move through a driving element so as to realize the simulation of the walking motion of legs and the linkage of all joints of the lower limbs, effectively reduce the use of driving elements, simplify the structure of a trainer, reduce the complexity of a system, and save cost; furthermore, a movement locus is exclusive, therefore the trainer is convenient to operate and control, and is effective to help patients carry out the movement locus of the lower limbs. By setting an adjusting component, the sizes of all driven rods can be adjusted according to need of a patient, and then the swing angles and angle scopes between the thigh rods and the shank rods can be adjusted to be applicable to the demands of the patients of different heights.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation equipment, and in particular relates to a lower limb rehabilitation training device. Background technique [0002] Rehabilitation training is an effective means for stroke patients, patients with spinal injuries and other trauma patients to recover motor function. At present, one-on-one physicians are usually used for rehabilitation training, which is low in efficiency and high in intensity. With the rapid increase in the number of patients, saving treatment time has become an issue of current concern. [0003] Rehabilitation robot is a new type of robot that has emerged in recent years, and it belongs to the category of medical robots. Divided into rehabilitation training robots and auxiliary rehabilitation robots, the main function of rehabilitation training robots is to help patients complete various motor function recovery training, such as walking training, arm exercise traini...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing lower limb rehabilitation robots use a suspended weight-reducing walking mechanism to assist patients in walking, but this mechanism is only suitable for patients in the late stage of rehabilitation who have the ability to walk, and does not pay enough attention to patients who need early training. Due to the limitations of the traditional exoskeleton structure, the knee joint motor needs to be connected to the arm of the lower limb, which places a greater burden on the hip joint motor and limits the flexibility of the exoskeleton.

The multi-position bed-type rehabilitation training robot can adapt to patients in different rehabilitation training stages, but the lower limb rehabilitation training structure of most of these robots still adopts a multi-joint exoskeleton training mechanism, which is configured at the hip, knee and ankle joints of the lower limbs. One drive motor realizes the movement, which makes the mechanism complex, high cost, and difficult to control
