Problems solved by technology

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 new nerve tissue will not grow according to the original shape of the nerve tissue, but will grow in the burned area. Neuromas grow randomly on the dead nerve tissue. When neuromas form, the human nerves will be more easily compressed and injured, which will cause pain in the affected area and recur, and even cause more severe pain.

experiment example 1

[0067] Experimental Example 1: Behavioral Test of Pain in Rat Foot - Von Frey (VF) Test

[0068] SD rats (Sprague-Dawley rats, BioLASCO, Taiwan co., Ltd.; Taiwan), each weighing about 275 to 350 grams, were used from the Central Laboratory Animal Center of Shin Kong Hospital, Taiwan. The fifth lumbar nerve of SD rats was subjected to nerve ligation (Spinal nerve ligation, SNL). After the pain behavior developed stably for several days and conformed to the clinical pain development model, the electrical stimulation unit of the present invention was implanted, and high-frequency therapy was started. electrical stimulation. This experimental example was divided into a control group (N=3) and an experimental group (N=7) according to different electrical stimulation measures. The experimental group continued to observe the pain behavior for 7 days after the operation. 5 minutes each time, a total of 3 sessions of high-frequency electrical stimulation, and observe the pain behavior...

[0070] Experimental Example 2: Neuroelectrophysiological Test

[0071] SD rats were divided into experimental group and control group, experimental group ( Figure 17B ) received 5 minutes of high-frequency electrical stimulation, while the control group ( Figure 17A ) did not receive any electrical stimulation, and the two groups received sciatic nerve high-current stimulation (2.5T, Cresponse threshold) under the same conditions to induce obvious A responses (corresponding to A-fiber) and C responses (corresponding to C-fiber) in the dorsal horn of the ipsilateral spinal cord. fiber). Before the intervention measures (high-frequency electrical stimulation for 5 minutes or pause recording for 5 minutes), the baseline value (Baseline) was measured in advance for 30 minutes (18 samples, 100 seconds interval). After the interventional measures were applied, the sciatic nerve was stimulated with high current every 30 minutes, and the recording was continued for 2 hours. Five e...

Abstract

The present application discloses an electrical stimulator which is applied to a target region of an electrical stimulation organism so that the pain is reduced without causing an abnormal feeling. The electrical stimulator comprises at least one electrical stimulation unit. The electrical stimulation unit has at least one first electrode and at least one second electrode. The electrical stimulation unit receives the high frequency electrical stimulation signal, causing the first electrode and the second electrode to generate an electric field. The electric field range covers the target area and the electric field intensity ranges from 100V / m to 1000V / m to electrically stimulate the target area. The frequency range of the high frequency electrical stimulation signal is between 200KHz and 1000KHz.

Description

technical field [0001] The invention provides an electric stimulator, especially an electric stimulator for electrically stimulating a target area of ​​a living body, so as to reduce pain without producing abnormal sensation. Background technique [0002] The human nerve is mainly used as the conduction path of the instructions (current) issued by the brain. The human nerve has a threshold, and the threshold of the damaged nerve area tends to decrease, so the human body is particularly prone to feel discomfort in the damaged nerve area. Comfortable soreness can lead to chronic pain in the long run. [0003] Clinically, a continuous radiofrequency (CRF for short), also known as electrocautery, is applied to a variety of complications, such as: cervicogenic headache, occipital neuralgia, cervical spine injury, intercostal neuralgia and other pains . The continuous radio frequency stimulation method is mainly to insert electric cautery needles near the relevant nerve tissue o...
