Abstract

The present application relates to the technical field of medical devices, in particular to a deep intracranial electrode, comprising a flexible wire, an electrode contact, a plug and an inelastic sleeve. One end of the flexible wire is connected to the electrode contact, and the other end is connected to the electrode contact. In connection with the plug, the inelastic sleeve can be sleeved on the flexible wire, one end of the inelastic sleeve can be connected with the plug, and the other end can be connected with a fixing nut fixed to the skull. When the deep intracranial electrode is subjected to a pulling force, the fixing nut can block the movement of the inelastic sleeve, thereby preventing the deep intracranial electrode from being pulled out.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intracranial deep electrode. Background technique [0002] Before surgery in patients with intractable epilepsy, intracranial EEG monitoring with deep intracranial electrodes is required to determine the location of the epileptogenic foci. The deep intracranial electrode generally includes electrode contacts and plugs, and the electrode contacts are electrically connected to the plug. The end of the deep intracranial electrode with the electrode contacts can be surgically implanted into the patient's brain, and the plug can be connected to the EEG. , so that the electrophysiological signals collected by the electrode contacts can be transmitted to the EEG. [0003] Before testing, it is necessary to drill a hole in the patient's skull, and then screw a guide screw into the patient's skull, and the guide screw is also threadedly connected with a fixing nut, which can l...
