Device for determining the position of a treatment area in a patient's brain has an electrode that can be precisely and reproducibly positioned in the brain ensuring that healthy tissue is protected as far as possible

摘要

Device for determining the position of a treatment target area (1, 1') in the brain (2) with a positioning device placed on the patient's head that is used to position an electrode (6) at given spatial coordinates with a given incidence direction. The electrode is designed so that it has an effective direction (9) for detection of neuronal processes that is perpendicular to the electrode longitudinal axis and can be adjusted for 360 deg around the electrode. Further is has position and angle determination devices.
