In order to perform minimally invasive interventions in the skull region according to prior art, a spherical guide for a medical instrument is placed in the burr hole of the skull in such a way that the medical instrument can be swiveled in all directions while being mounted so as to be axially movable through the spherical guide. The aim of the invention is to create an aiming device which allows both a comparable guiding element and the medical instrument to be positioned and retained in the burr hole. Said aim is achieved by an aiming device in which an aiming pencil (3) is placed directly on the burr hole (2) of the body part (1) that is to be examined and is retained there by means of a positioning arm (8). |
