Description

High frequency electromagnetic field stimulator changing neural threshold

The invention relates to a high frequency electromagnetic field stimulator for changing a neural threshold, in particular to a low voltage high frequency signal with a voltage ≦10V and a frequency between 200KHz and 800KHz, and a second interval from the nerve to be stimulated. The electromagnetic field generated by the electrical stimulator is surrounded by the nerve to be stimulated, and the nerve to be stimulated is subjected to low-intensity electromagnetic stimulation to increase the threshold of the nerve region stimulated by electromagnetic stimulation.

The human body is mainly used as the conduction path of the command (current) emitted by the brain, in which the human body has a threshold value, and the threshold value of the damaged God region is often lowered, and thus the human body is particularly damaged in the area of the god. It is easy to feel the soreness of discomfort, and it will form chronic pain after a long time.

Clinically, a continuous radiofrequency (CRF), also known as electrocautery, is used for a variety of complications, such as: cervicogenic headache, occipital neuralgia, cervical spine injury, intercostal neuralgia, etc. The continuous radio frequency stimulation (CRF) method mainly involves inserting an electrocautery needle into the vicinity of the relevant nerve tissue of the affected part, and using the high temperature generated by the continuous high-frequency electric stimulation to burn the nerve tissue of the affected part, also because The nerve tissue of the affected part is burned to death, so as to achieve an analgesic effect in the affected part after the operation. However, when the self-repair function of the human body is activated, the burned nerve tissue will repair itself. Once the nerve tissue is repaired by itself, the newly added nerve tissue does not grow in the shape of the original nerve tissue, but it will burn out. On the nerve tissue Arbitrarily grow to form a neuroma. When a neuroma is formed, the human body is more likely to be oppressed and injured by the gods, causing the pain in the affected part to be repeated, and even the pain in the affected part will be more serious.

Clinically, another pulsed radiofrequency (PRF) is mainly used to insert an electrode needle into the vicinity of the relevant nerve tissue of the affected part, and use a 45V high-voltage RF current to stimulate the current twice a second. 20 microseconds (ms), stimulate the nerve tissue of the affected part, and use the pulse intermittent method to suppress the high voltage current from increasing during the stimulation process, so that the thermal effect of the stimulation process can be lower than 42 degrees Celsius, avoiding the high voltage current stimulation. The nerve tissue is destroyed or necrotic by high temperature, preventing the formation of neuroma after surgery.

US Patent No. 6,246,912, "Modulated high frequency tissue modification" discloses that a positive electrode electrode shaft 1 and a negative electrode ground plate 16 are respectively connected to the high frequency pulse generator 11, and the positive electrode shaft 1 is inserted into the human body, and the electrode is placed. The electrode end 2 of the shaft 1 is located in the affected part of the nerve, and the grounding piece 16 of the negative pole is attached to the outside of the human body to form a circuit loop. The high-frequency pulse generator 11 generates a radio frequency pulse current of several tens of volts and high voltage, and stimulates the affected part of the nerve via the electrode end 2 to suppress the temperature of the stimulation process from rising, and to prevent the nerve tissue from being destroyed or necrotic by the high temperature. However, the user must precisely control the pulse intermittent time to effectively control the rise of the high voltage stimulation current.

In order to solve the problems and deficiencies of the above-mentioned prior art, the present invention discloses a high frequency electromagnetic field stimulator that changes a neural threshold, including at least one electrical stimulator. The electrical stimulator comprises at least one positive electrode end and at least one negative electrode end, the first spacing distance between the positive electrode end and the negative electrode end is insulated, and the positive electrode end and the negative electrode end are separated from each other by a nerve The second separation distance, and the electric stimulator electrically conducts a voltage, so that the voltage is ≦10V and the frequency The rate is between 200KHz and 800KHz, and an electromagnetic field is generated from the positive electrode end and the negative electrode end of the electric stimulator, so that the electromagnetic field is surrounded by the nerve to be stimulated to electromagnetically stimulate the nerve to be stimulated. The low-intensity, low-temperature high-frequency electromagnetic stimulation can increase the threshold of the nerve region stimulated by electromagnetic stimulation, thereby reducing the nerve conduction capability of the nerve region stimulated by electromagnetic stimulation, thereby effectively reducing the nerve pain of the patient.
