Medical device for moving a medical instrument

The aim of the invention is to move a medical instrument (2) by means of a medical device (1) in the longitudinal direction of the device and in the rotation direction transversely about the longitudinal direction by an actuating apparatus (3). This aim is achieved in that the medical instrument (2) is connected to at least one first magnetic element (18, 19) and the actuating apparatus (3) contains at least one second magnetic element (20, 21) or is connected thereto; the actuating apparatus (3) is movable together with the at least one second magnetic element (20, 21) in the longitudinal direction of the device and in the rotational direction about the longitudinal direction in question and is movable together with the at least one second magnetic element (20, 21) in the longitudinal direction of the device and in the rotational direction about the longitudinal direction in question and permits, by means of magnetic coupling between the at least one second magnetic element (20, 21) and the at least one first magnetic element (18, 19), moving same together with the medical instrument (2).
