The invention relates to an aiming device () for the placement of Kirschner-wires in orthopedics/traumatology. The aiming device () comprises an adjustable aiming block () which is displaceably attached to a forceps (). The fixation of the aiming device at the bone () can be varied by clamping the forceps () more or less strongly. The aiming block () can be displaced to the periost () and be fixed. The aiming device () according to the invention allows the alignment of the guidance () of the Kirschner-wire () about an axis of rotation (). Before the Kirschner-wire () is inserted in the bone () its position and direction can be intraoperatively represented and aligned in at least two non-parallel planes of projection (P, P) by means of fluoroscopy and/or navigation. Repeated drilling and mistaken positioning of the Kirschner-wire () can so be avoided. Thus, allowing to reduce the time of operation and the exposure of the patient to radiation.
