Description

Epileptic electrode implantation equipment

Technical Field

The invention belongs to the field of medical appliances, and particularly relates to epileptic electrode implantation equipment.

Background

Epilepsy is a chronic neurological disorder caused by abnormal and excessive brain neuronal activity, with EEG signals being the most common and effective method of detecting epilepsy.

Epileptic patients often respond poorly to antiepileptic drugs, and long-term administration of drugs can severely affect the patient's body, and seizures can easily occur if the drug is not administered in time. Surgical removal of an epileptic focal zone is a relatively effective method of treating epilepsy, but it is difficult to treat epilepsy when the area is relatively large or the location is inconvenient for surgery.

Therefore, it is necessary to invent a device that can timely remind the patient to avoid or reduce seizures by means of electrical stimulation manually or automatically, and current implantation devices often use screws for fixation, which can cause secondary injury if it needs to be removed or replaced.
