Abstract

A navigation aid for introducing an elongate medical penetration element into a patient. An X-ray image, containing a target region for the penetration element in a desired target position in a patient, is superimposed in alignment with video sequence images, containing at least in part the penetration element, to form a combination image sequence. The penetration element is captured in a start position and a desired penetration course of the penetration element at least to the target region of the penetration element in a desired target position, is visually displayed in the combination image sequence. A penetration element, such as a medical implant and/or instrument, in particular a K-wire (Kirschner wire), may carry a number of markers, such as additional bodies, coatings, elevations, and/or depressions, said markers altering a light reflection, are situated on and/or at and/or in the penetration element.
