Description

Technical Field

[0001] The present disclosure relates to the field of electrode technology, and in particular to a high-precision electrode for transcranial nerve stimulation. Background Art

[0002] Cranial microcurrent stimulation (CES) is a completely different treatment method from traditional drug therapy and electroconvulsive therapy. It stimulates the brain with low-intensity microcurrents, changes abnormal brain waves in the patient's brain, and prompts the brain to secrete a series of neurotransmitters and hormones that are closely related to anxiety, depression, insomnia and other diseases, thereby achieving the treatment of these diseases. Compared with drug therapy, this treatment method has no side effects and stable efficacy, so it has been widely used in Europe, the United States and other countries as a safe and effective treatment for anxiety, depression, insomnia and related diseases.

[0003] Transcranial direct current stimulation (tDCS) is a non-invasive technique that uses constant, low-intensity direct current (1-2 mA) to regulate the activity of neurons in the cerebral cortex. tDCS has two different electrodes and their power supply battery devices, plus a control software to set the output of the stimulation type. There are three types of stimulation methods, namely, anodal stimulation, cathodal stimulation, and sham stimulation. Anodal stimulation usually enhances the excitability of neurons at the stimulation site, while cathodal stimulation reduces the excitability of neurons at the stimulation site. Sham stimulation is mostly used as a control stimulation. Unlike stimulation techniques such as transcranial electrical stimulation and transcranial magnetic stimulation, tDCS does not cause neuronal discharges through suprathreshold stimulation, but works by regulating the activity of neural networks. At the neuronal level, the basic mechanism of tDCS regulation of cortical excitability is to cause changes in resting membrane potential hyperpolarization or depolarization depending on the polarity of the stimulus. Anodal stimulation usually increases the excitability of the cortex, while cathodal stimulation reduces the excitability of the cortex. Membrane polarization is the main mechanism of tDCS action immediately after stimulation.

[0004] However, in addition to the immediate effect, tDCS also has a post-stimulation effect. If the stimulation time lasts long enough, the change in cortical excitability can last up to 1 hour after the stimulation ends. Therefore, its mechanism of action cannot be explained solely by the polarization of neuronal membrane potential. Further studies have confirmed that in addition to changing the polarity of membrane potential, tDCS can also regulate the microenvironment of synapses, such as changing the activity of NMDA receptors or GABA, thereby regulating synaptic plasticity. The after-effect mechanism of tDCS is similar to the long-term facilitation of synapses. Animal studies have found that a sustained increase in postsynaptic excitatory potentials can be observed when anodal stimulation is applied to the motor cortex. The regulation of cortical excitability depends on the level of membrane polarization during tDCS stimulation, and the after-effect after the stimulation ends is mainly due to the activity of synapses in the cortex.

[0005] tDCS can also modulate the excitability of remote cortical and subcortical areas. tDCS anodal stimulation of the premotor cortex can affect changes in the excitability of connected remote cortical areas. Stimulation of the left hemisphere M1 area not only affects the corticospinal circuits involved in generating motor evoked potentials, but also modulates transcallosal inhibition of the contralateral hemisphere through inhibitory interneurons.

[0006] However, the existing stimulation electrodes have a complex structure, are inconvenient for patients to use, and the stimulation effect is not very obvious. Utility Model Content

[0036] In this embodiment, a glue injection hole 17 is provided on the top of the shell 1 and the glue injection hole 17 is connected to the groove 14 so that glue can be injected into the electrode 2 disposed in the groove 14 through the glue injection hole 17 to bond the electrode 3 to the lower shell 4.

[0037] like Figure 6 As shown, at least one protrusion 141 is provided on the bottom surface of the groove 14. After the electrode 2 is installed in the groove 14, the protrusion 141 lifts the electrode 2 so that there is a gap between the electrode 2 and the bottom surface of the groove 14. The conductive paste flows onto the electrode 2 through the gap, so that the conductive paste flows evenly through the gap to the contact surface between the electrode 2 and the bottom surface of the groove 14, thereby further improving the stimulation effect of the high-precision electrode for transcranial nerve stimulation in this embodiment.

[0046] Optionally, the inner diameter of the through hole 20 is smaller than the inner diameter of the mounting hole 21 .

[0047] In the present embodiment, the inner diameters of the connecting head 12, the connecting column 11, and the through hole 20 on the shell 1 are set to be smaller than the inner diameter of the mounting hole 21 on the electrode 2, so that the upper surface of the electrode 2 can be positioned through the hole wall of the mounting hole 21, thereby playing the role of fixing the electrode 2, thereby preventing the electrode 2 in the present embodiment from falling off the shell 1 due to the patient's own shaking or accidental collision with the outside world during the use of the high-precision electrode for transcranial nerve stimulation in the present embodiment.

[0048] like Figure 3 As shown, an annular groove 22 is provided between the connecting column 11 and the top of the housing 1 .

[0049] In the present embodiment, an annular groove 22 is provided between the connecting column 11 and the top of the shell 1, so that the connecting column 11 can be tightly clamped to the target setting position on the electrode frame through the annular groove 22, so as to prevent the high-precision electrode in the present embodiment from falling off from the target setting position on the electrode frame due to the patient's own shaking or external accidental collision during the use of the high-precision electrode for cervical and cranial nerve stimulation in the present embodiment.

[0050] Preferably, the connector 12, the connector column 11, and the housing 1 are integrally formed to save processing technology.

[0051] Preferably, the connecting head 12, the connecting column 11, and the shell 1 are all made of hard silicone to prevent the electrode 2 in this embodiment from falling off the shell 1 due to the patient's own shaking or external accidental collision when using the high-precision electrode for transcranial nerve stimulation in this embodiment.
