Intracranial electrode integrated with macro and micro electrodes

Abstract

The invention provides an intracranial electrode integrated with macro and micro electrodes. The intracranial electrode integrated with the macro and micro electrodes comprises a sleeve (3), a wire (4) is arranged in the sleeve (3), wherein a macro electrode (1) and a micro electrode (2) are integrated on the side wall of the sleeve (3); and the macro electrode (1) and the micro electrode (2) respectively transmit signals received by the macro electrode (1) and the micro electrode (2) outwards through the wire (4). In the axial direction of the sleeve (3), the macro electrode (1) and the micro electrode (2) are spaced from each other and are arranged on the side wall of the sleeve (3) in a mutually insulated manner.

Description

technical field [0001] The present application relates to the technical field of stereotactic electroencephalography, in particular to an intracranial electrode integrated with macro and micro electrodes. Background technique [0002] Stereotactic electroencephalography (SEEG) is also known as stereoscopic three-dimensional electroencephalography. This technology introduces the positioning method from 2D to 3D by introducing EEG technology into the 3D level. It is based on clinical symptoms, cortical discharge, and neuroanatomy, and uses stereotaxic methods to place electrodes. This method uses electrodes to cover the brain in three dimensions, so as to achieve the purpose of accurately locating the lesion and improving the treatment effect. [0003] Patients with drug-refractory epilepsy need surgery to achieve the goal of radical treatment. Preoperative evaluation is an important factor affecting the effect of surgery. Existing non-invasive examination methods cannot ac...

Problems solved by technology

This leads to epilepsy patients having to undergo long-term intracranial EEG monitoring after implanting deep intracranial electrodes to capture a sufficient number of seizure events, which intensifies the consumption of medical resources and increases the risk of infection and other diseases. risk of complications

Even some patients with epilepsy did not have epileptic seizures during the whole process of EEG monitoring, which led to the failure of diagnosis

[0010]The root cause of this situation is that the existing intracranial deep electrodes can only collect local field potential signals at specific positions in the brain, and medical workers can only Diagnosis and analysis based on the limited information that local field potentials can provide
