Deep intracranial electrode and medical instrument

Abstract

The invention discloses an intracranial deep electrode and a medical instrument. The intracranial deep electrode comprises an insulating support, a plurality of electrode contacts spaced apart at thefront end of the intracranial deep electrode, an electrically conductive terminal and an electromagnetic induction element, wherien the terminal is connected with the support body, the terminal is positioned at the front end of the support body, the electromagnetic induction element is arranged in the terminal, and the electromagnetic induction element is used for acquiring position information ofthe terminal. In the intracranial deep electrode according to an embodiment of the present invention, the electromagnetic induction element for indicating position information of the end is arrangedin the end, the positional information of such a head can be fed back to an external device through an electromagnetic induction element so that the path of the intracranial deep electrode can be traced, thereby improving the accuracy of determining the position of each brain region through the intracranial deep electrode, thereby improving the accuracy of surgical removal of a lesion (e.g., an epileptic lesion).

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an intracranial deep electrode and a medical equipment. Background technique [0002] In related technologies, deep intracranial electrodes can not only detect electrophysiological signals of the cerebral cortex, but also penetrate deep into the brain to obtain electrophysiological signals of different regions of the brain, thus being widely used in the diagnosis of epilepsy and neurosurgery. middle. When observing the contacts through deep intracranial electrodes to determine the location of each brain region, it is necessary to combine the CT images after the electrodes are placed with the MR images before the electrodes are placed to achieve indirect software isolation. However, the above-mentioned method of determining the position of each brain region through intracranial deep electrodes will be affected by the accuracy of different software partitions, and will a...

Problems solved by technology

However, the above-mentioned method of determining the position of each brain region through intracranial deep electrodes will be affected by the accuracy of different software partitions, and will also be affected by whether the brain tissue of each region of the patient has a slight shift compared with the pre-operation MR.

This also leads to the fact that the considered electrode position is not the actual position of the electrode, thus affecting the accuracy of surgical resection
