Embodiment 1

[0032] as attached figure 1 As shown, a deep intracranial electrode of the present invention consists of an insulating tubular carrier 3, a plurality of electrode points 2 embedded in the tubular carrier 3, located in the carrier and connected to the electrode points 2 and the connectors at both ends ( (not shown in the figure) consists of an insulated wire 1, an elastic core 4 in the tubular direction corresponding to the section of the electrode point 2, and a terminal 5 at the front end of the electrode.

[0033] In the embodiment 1 shown in the drawings, the further feature of the present invention is that a stainless steel ring 6 is arranged inside the tubular carrier 3 corresponding to the electrode point 2, so that the electrode has good sealing performance. When the electrode is placed in the human brain, because the intracranial pressure is greater than the external atmospheric pressure, the intracranial tissue fluid and cerebrospinal fluid will be pressed into the in...

Abstract

The invention discloses an intracranial deep electrode. The intracranial deep electrode is composed of an insulated tube-type carrier, multiple electrode points, an insulated wire, an elastic core and an end, wherein the electrode points are embedded in the tube-type carrier, the insulated wire is located in the carrier, the two ends of the insulated wire are connected with the electrode points and plug connectors respectively, the elastic core is arranged in the tube direction corresponding the electrode point sections, and the end is arranged at the front end of the electrode. Because elastic rings are arranged at the positions, corresponding to the electrode points, inside the tube-type carrier, the electrode has excellent sealing performance. Because the edges of the electrode points are provided with ground corners, the electrode points will not scratch brain tissue which the electrode points pass through when the electrode is implanted or taken out, and operation risks are reduced. When the end is used as an electrode point, the electrode can puncture and enter the brain more smoothly and is prevented from deviating from a preset path in the inserting process. Besides, the end can perform electrocoagulation damage or radiofrequency ablation to damage diseased tissue of the brain. Meanwhile, a doctor can calculate the implantation depth easily to reduce operation injury.

Description

technical field [0001] The invention relates to an electrode for sensing and recording intracranial biological waves and conducting extracranial electric pulses to the intracranium, in particular to an intracranial deep electrode. Background technique [0002] The human brain continues to emit weak bioelectrical signals, which are called brain waves, which are an intuitive reflection of brain activity. By monitoring and studying these tiny electrical signals, we can understand the real-time physiological state of the brain. Brain diseases or brain tissue lesions can cause abnormal brain tissue discharges, especially epilepsy, a disease that can cause strong abnormal discharges in the brain. Monitoring EEG signals can help doctors determine the type of disease and the location of the disease. In order to determine the treatment Scenarios provide valuable information. [0003] People first used disc-shaped metal electrodes with wires to stick on the scalp to collect the EEG ...
