Technical Field

The invention belongs to the technical field of medical devices, and particularly relates to a paralyzed limb movement function reconstruction system adopting an electric needle and an electric moxibustion medical technology.

Background

According to the theory of traditional Chinese medicine, the cause of the quadriplegia of the apoplexy patient is the empty and deficient of the qi transmission of the channels and collaterals caused by the damage of the brain and marrow spirit. Common treatment methods include taking traditional Chinese medicine and acupuncture. The traditional acupuncture therapy is to insert a filiform needle into a specific acupoint of a patient's body by hand and to use acupuncture techniques such as twirling, lifting and inserting, etc., while the moxibustion therapy is to smoke and bake the specific acupoint with a burning moxa cone. The effects of both therapies can only be slowly manifested by multiple treatments over a longer period of time. In other words, for paralyzed limbs, the traditional Chinese medicine acupuncture and moxibustion cannot show the movement function in the treatment process. 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 special point is that in the treatment process, the limbs can generate harmonious actions, and the rehabilitation of the limb movement function can be realized by depending on the brain remodeling mechanism.
