摘要：
The invention relates to a device for guiding a medical instrument (2) inserted into a natural duel (101) or an artificial duct of a patient in order to bring at least a distal end (1) of the instrument in proximity to an internal organ (100), the device comprising an articulated arm (3) with a plurality of degrees of freedom, for moving a proximal end (4) of the instrument, and controlled blocking means (7) for blocking the degrees of freedom of the articulated arm. According to the invention, the blocking means are designed in such a way that, for at Mast one of the degrees of freedom, a blockage imposed on said degree of freedom can be enforced when an outer stress exerted on the instrument (2) exceeds a predetermined threshold.
