Rehabilitation training hand and rehabilitation training method

Abstract

The invention discloses a rehabilitation training hand and a rehabilitation training method. The rehabilitation training hand comprises a drive portion and a mechanical portion. The mechanical portion comprises a palm portion body, a finger regulation portion body and a man-machine integration portion body. According to the palm portion body, a palm fixing plate is connected with a palm face of a patient hand through a palm binding belt and connected with a carpal articular face of the patient hand through an arm binding belt. A finger sliding rail and a thumb base are arranged on the palm fixing plate. The finger regulation portion body comprises support rods rotating around coxa pins, knuckle sliders sliding along sliding grooves of the support rods. The coxa pin of the thumb is connected to a thumb base, and coxa pins of the other four fingers are arranged on coxa sliders which are arranged on the finger sliding rail and slide along the finger sliding rail. The man-machine integration portion body comprises a thumb sleeve connected with a remote thumb knuckle of the patient hand and finger sleeves connected with remote knuckles of the other four fingers of the patient. The rehabilitation training hand is small in structure, light and convenient, suitable for being worn on the patient hand and capable of completing hand expanding and finger and palm training actions.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation, in particular to a rehabilitation training hand and a rehabilitation training method. Background technique [0002] At present, the rehabilitation training hand for the hand function recovery of stroke and cerebral hemiplegia patients is mainly to realize the hand grasping, hand opening and other actions in daily life. In fact, for rehabilitation training, the flexibility of the thumb, The mutual coordination between the thumb and other fingers or palms is more conducive to the completion of finger function rehabilitation, and the rehabilitation of each finger can be evaluated in a targeted manner. The research and development of rehabilitation robotic hands at home and abroad has never stagnated. The research goal of more mature rehabilitation training hands at home and abroad is mainly to restore the overall motor function of the hand. [0003] The rehabilitation assisting hand ...

AI Technical Summary

Problems solved by technology

[0006] In short, in the prior art both at home and abroad, there are generally the following defects: (1) rehabilitation assisting hands are generally heavy, one is immovable, and is used for rehabilitation training at a specific location, and the other is wearable, and the weight is basically more than 400g, for the affected hand, it is not easy to wear it for a long time; (2) The affected hand worn in the rehabilitation assisting hand will be confined in the finger cot worn and unable to move. For fingers with different degrees of damage, it will be difficult to adapt It is more difficult; (3) The movements are still grasping and palm opening in the traditional sense, and other movements are affected by the mechanical structure. It is necessary to consider the complex structure of the human body to complete the design of various movements, such as Gifu University, Japan The rehabilitation assisting hands are all made of metal structural parts, and the system is quite huge
