The invention relates to an operation system for performing surgical interventions by using a surgical instrument (3) on a patient (1). The operation system comprises an X-ray unit (2) for taking an X-ray image of at least one area of the patient (1), whereby the recorded X-ray image is pictorially represented by an output device (11). The operation system also comprises a position detection system for detecting the position of the X-ray unit (2) as well as the position of the surgical instrument (3), and comprises a processing device (10) for processing the detected positions and for continuosly superimposing a representation of the surgical instrument (3) in the displayed the X-ray image. The superimposition of the X-ray image and of the representation of surgical instrument ensues to-scale according to the actual spatial positions between the position of the recorded area of the patient (1) and of the position of the surgical instrument (3). The invention also relates to a method, which is used in the operation system and which is provided for controlling a surgical instrument during the intervention.
