Intracranial electrode module and intracranial electrode implantation device

Abstract

The embodiment of the invention relates to the technical field of medical equipment, and particularly discloses an intracranial electrode module and an intracranial electrode implantation device.The intracranial electrode module comprises a substrate, at least two electrode sampling point sets and a conductive wire, and the electrode sampling point sets are arranged on the substrate and exposed out of the surface of the substrate; the electrode sampling point group comprises electrode sampling points; the conductive wires are arranged on the substrate and are electrically connected with the electrode sampling points; the intracranial electrode module comprises a sampling part, electrode sampling points are located on the sampling part, and the sampling part can be switched between a gathering state and an unfolding state; in the unfolding state, the sampling part is unfolded to be in a fan shape, the sampling part is provided with a first side and a second side which are oppositely arranged in the radial direction of the sampling part, and the electrode sampling point groups are arranged at intervals in the unfolding circumferential direction of the sampling part; and in the gathering state, the second side is gathered. By means of the mode, the intracranial electrode module can be implanted into the human body in the gathering state and then switched into the unfolding state, and therefore the intracranial electrode module can be implanted into the human body through a bone window smaller than the intracranial electrode module.

Description

technical field [0001] The embodiment of the present application relates to the technical field of medical devices, and in particular to an intracranial electrode module and an intracranial electrode implantation device. Background technique [0002] Under normal circumstances, the human brain produces weak bioelectrical signals on the surface of its cortex with certain regularity. When there are pathological lesions in the brain, the discharge pattern of the EEG signal will change significantly, and some lesions will cause special changes in the discharge pattern of the brain electrical signal. Clinically, by observing the special changes in these discharge patterns, the human brain can be affected. disease diagnosis and treatment. [0003] There are currently two ways to collect EEG signals. One is the collection of scalp EEG signals, that is, a certain number of electrodes are placed on the scalp to collect EEG signals. This method is characterized by non-invasive and ea...

Problems solved by technology

[0004] Intracranial cortical electrodes are mainly divided into strip-shaped cortical electrodes and sheet-shaped cortical electrodes. In order to have a larger detection range, sheet-shaped cortical electrodes are often used. However, the inventor of the present application found in the process of implementing the application that : At present, traditional sheet-like cortical electrodes need to open a larger bone window than sheet-like cortical electrodes in the patient's skull during use, which is not conducive to patient repair and postoperative care
