Wearable exoskeleton hand function rehabilitation trainer

Abstract

The invention relates to a wearable exoskeleton hand function rehabilitation trainer and belongs to the technical field of rehabilitation engineering. The wearable exoskeleton hand function rehabilitation trainer comprises a four-finger drive mechanism, a thumb drive mechanism, a back supporting plate and finger mechanisms. The hand back supporting plate is fixedly connected with the four-finger drive mechanism, a motor is connected with the index finger through gear movement and drives the index finger to move, four fingers are connected through connecting parts at the near ends of the four fingers, and movements of other fingers are driven by the movement of the index finger. One side of the back supporting plate is connected with the thumb drive mechanism. The wearable exoskeleton hand function rehabilitation trainer can finish opposite movement of the thumb and the index finger, the movement speed of an index finger mechanism can be set according to the rehabilitation situation of a patient. In addition, a wearable function of the trainer can be achieved through connection of worn gloves and the hand. The wearable exoskeleton hand function rehabilitation trainer is simple in structure, light and convenient to operate and can be used for rehabilitation training of the patient in a community and at home by himself / herself.

Description

technical field [0001] The invention relates to a wearable exoskeleton hand function training device which imitates the finger-to-finger movement of a human body. Background technique [0002] A pair of healthy hands occupies a very important position in people's life. However, for some elderly people and external injuries that cause hand spasms and other injuries, it has caused great difficulties in the lives of patients. At the same time, the treatment of hand injuries is very difficult, and rehabilitation training after treatment is greatly limited. For hand rehabilitation treatment in the traditional sense, the patient regularly goes to the hospital to carry out the rehabilitation training of the opponent by means of some relatively large hand trainers. [0003] The research on limb rehabilitation equipment in China started relatively late, and there are mainly Tsinghua University, Shanghai Jiaotong University, Fudan University, Harbin Institute of Technology, etc. who ...

Problems solved by technology

However, the current molded products are difficult to fully meet the requirements of patients

The application range of upper limb rehabilitation equipment is limited to local joints, and the degree of intelligence is not high, and the wearability is poor

For the repetitive training of hemiplegic upper limbs in foreign countries, MIT designed and completed the first upper limb rehabilitation training robot system MIT-MANUS[8] in 1991. Unlike general industrial robots, MIT-MANUS has considered safety, stability and Compliant for close physical contact with the patient, but not wearable
