Rehabilitation instrument for training rotation of wrist joints

Abstract

The invention discloses a rehabilitation instrument for training rotation of wrist joints, belongs to the field of rehabilitation assistant tools, and relates to a rehabilitation device for rehabilitating wrist joints of hemiplegic patients. The rotating range, allowed by the rehabilitation instrument, of a wrist joint can be adjusted, and the driving force of the rehabilitation instrument is provided by a reducing motor and passed to a palm of a patient through a coupler, a magnetic powder clutch, a stepped shaft and a hand holding board sequentially so as to drive the patient to perform rotation movement of the wrist joint. The magnetic powder clutch is taken as a damper for mechanism movement, and different assistance functions can be achieved by controlling current of the magnetic powder clutch. Forward and backward rotation ranges of round discs and the hand holding board are changed by changing the relative position of nuts and the round discs in the rehabilitation instrument so as to adjust the rotation ranges of the wrist joints; and the rehabilitation instrument further comprises a simple form and is provided with three work modes of a passive mode, an assistance mode and a damping mode. The rehabilitation instrument is simple in structure, novel in design, safe and reliable, and can estimate and record rehabilitation conditions of the patient to provide a certain treatment standard for doctors.

Description

technical field [0001] The invention belongs to the field of rehabilitation aids, in particular to a rehabilitation device aimed at rehabilitation of the wrist joints of hemiplegic patients. Background technique [0002] According to statistics, more and more stroke patients will have different degrees of sequelae after surgery. How to make stroke patients fully recover after surgery has become a difficult problem in the current medical field. The traditional rehabilitation treatment method is mainly one-on-one manual treatment by the treating physician, and simple rehabilitation equipment is attached. With the increasing number of patients with hemiplegia, it is difficult to solve the rehabilitation needs of patients by simple traditional treatment methods. In order to solve these problems, the development of intelligent rehabilitation equipment has become particularly important. These equipment can not only solve the problem of insufficient manpower and physical strength ...

AI Technical Summary

Problems solved by technology

[0004] The current hemiplegia rehabilitation equipment is mostly multi-joint rehabilitation equipment. Because these rehabilitation equipment focus on the complexity of movement, the importance of single joint rehabilitation treatment is ignored, especially the rehabilitation of extremity joints, such as wrist joints and finger joints.

In the rehabilitation equipment only for single joint treatment, there are often only passive working mode and damping working mode based on the amount of exercise (such as wrist joint CPM machine), lack of power-assisted working mode
