Description

TECHNICAL FIELD

[0001] The utility model relates to the field of transdermal nerve electric stimulation, especially to a electroacupuncture stimulation device compatible with magnetic resonance for acupuncture brain atlas construction. BACKGROUND

[0002] Needling method refers to the acupuncture (usually refers to the filiform needle) is inserted into the patient's body according to certain angle under the guidance of traditional Chinese medicine theory, and the acupuncture techniques such as twirling and lifting are used to stimulate the specific parts of the human body to achieve the purpose of treating diseases, and it is widely used in the treatment of various indications. At present, acupuncture as a traditional Chinese medicine, the modern scientific mechanism is still unclear. In recent years, with the rise of non-invasive neural detection technology, functional magnetic resonance imaging (fMRI) technology has also been widely used in the treatment mechanism research of acupuncture.

[0003] Since the first article on fMRI-based acupuncture brain effect was published in 1999, a large number of studies have begun to use fMRI to observe the brain function changes of acupuncture at specific acupoints. fMRI scanning is carried out at the same time when acupuncture is carried out at a specific acupoint to observe the brain response, so as to clarify the specificity of acupoints. However, the current research has the problem of non-uniformity of experimental design, which may be an important factor for the inconsistency of the research results of the same acupoint, which poses a great challenge to the mechanism research of acupoint effect.

[0004] Brain atlas is a tool or model for visualizing and quantifying the structure and function of the brain. It helps to understand the organization and operation of the brain by dividing the brain into different regions and labeling and presenting the characteristics, connections and functions of these regions. It has important applications in the fields of neuroscience research, medical diagnosis, brain imaging analysis, etc. By observing the brain response mode while acupuncture is carried out at different acupoints and constructing acupuncture brain atlas, it helps to explain the mechanism of acupuncture and clinical acupoint selection. The construction of acupuncture brain atlas requires a large number of samples, so it is very important to control the heterogeneity of experimental design. Therefore, a special electroacupuncture stimulation device for acupuncture brain atlas construction is needed to reduce the heterogeneity of experimental design and improve the safety and accuracy of the experimental process.

[0005] One is to solve the magnetic resonance compatibility problem of the electric acupuncture device. The electric acupuncture device used in the clinic is to hold the alligator clip connected with the electric wire on the needle handle to realize current stimulation. However, because the non-magnetic metal such as pure copper lacks hardness, the material used for the spring in the alligator clip is iron. Iron as a magnetic material also makes the alligator clip unable to enter the magnetic resonance equipment. Therefore, the key point of the design needs to solve the problem of the connection between the needle body and the electric wire. The second is to solve the problem of the non-uniform placement of the electrode sheet in the current research. According to the literature, the current research places the electrode sheet at any position of the circle with the electric acupuncture stimulation point as the center and 1 inch or 2 inches as the radius (at the non-meridian non-meridian). The non-uniformity of this experimental design has a potential impact on the experimental results. Therefore, how to design the electrode sheet so that it has only one position for an acupoint is important for the uniformity of the experimental design. The third, because the subject is in the process of magnetic resonance scanning, it is possible to be away from the environment of the practitioner, so how to design a device to improve the stability of the needle body during electric stimulation is crucial for the safety of the experiment.

[0006] Based on the above research background and existing problems, a safe, uniform, accurate and magnetic resonance compatible electric acupuncture stimulation device is designed, which plays an important role in the construction of acupuncture brain atlas. Practical new type content
