According to the theory of traditional Chinese medicine, the cause of the quadriplegia of the stroke patient is that a part of nerve cells in the brain are damaged or inactivated due to cerebral hemorrhage or ischemia, so that meridian signals called 'qi' for controlling limb movement cannot be generated. The traditional rehabilitation therapy methods comprise medicine, physical therapy, acupuncture and moxibustion, operation methods and the like. For half a century, biomedical engineering researchers have developed methods of functional electrical stimulation. However, the treatment methods to date have some limitations in their effectiveness. Over 70 percent of hemiplegic patients have difficulty in recovering hand function. Taking acupuncture therapy as an example, the traditional acupuncture therapy is to use hands to insert acupuncture needles into a certain acupuncture point of the body of a patient and use acupuncture techniques such as twirling, lifting and inserting to treat paralysis diseases. Its therapeutic effect is slowly manifested by multiple treatments over a long period of time. In other words, for paralyzed limbs, the motor function cannot be shown in the course of the traditional Chinese medicine acupuncture treatment. The electric acupuncture apparatus widely used in hospitals at present replaces the traditional hand acupuncture therapy, and applies the artificially coded electric pulse to the acupuncture needle inserted into the acupuncture point, so as to realize various treatment purposes. For paralyzed limbs, the motor function can not be shown except the vibration of muscles in the electric needle treatment process. The invention aims to construct a meridian electric 'gas' signal bridging type limb movement function reconstruction device excited by an electro-acupuncture needle, which is used for carrying out reconstruction training on limb movement functions of hemiplegic patients including fingers so as to achieve the aim of rehabilitation.
