A skull clamping device for fixing and aligning a head of a patient for a medical intervention includes at least two ring elements arranged concentrically. A second ring element of the two ring elements is arranged within a first ring element of the two ring elements and is connected hereto by a second axis, about which the second ring element is mounted rotatably within the first ring element. The first ring element, which is outer relative to the second ring element, is mounted rotatably about a first axis that is orthogonal to the second axis. The skull clamping device also includes at least one motor-driven drive that drives the rotation of one or more of the at least two ring elements about the respective axis, at least two pins that are arranged in an innermost ring element of the at least two ring elements and are embodied to fix a head of a patient, two telescope bars that hold the at least two ring elements, and a control unit for the motor-driven actuation of the at least one motor-driven drive.
