Method and device for implanting intracranial electrode in arc track

The invention provides a method and device for implanting an intracranial electrode in an arc track. The method and the device are used for obtaining a puncture track with the single electrode passing through multiple intracranial target points. In the method for implanting the intracranial electrode, a radian-fixed arc puncture cannula is used for leading the electrode into the cranium, puncture positioning of the radian-fixed arc puncture cannula is achieved through the guidance of a radian-fixed arc guide cannula, the radian-fixed arc guide cannula is fixed to a positioning tool, the positioning tool is provided with a positioning frame and position-adjustable positioning points, the positioning points are provided with fixing parts, and when the arc guide cannula penetrates through the positioning points and is fixed through the fixing parts, positioning of the arc guide cannula is completed; when the arc guide cannula is positioned, the circumference of the circle where the arc of the arc guide canula is located passes through the multiple intracranial target points. According to the implanting method and the orienting device, the multiple target points are stimulated with the single electrode.
