摘要

The invention concerns a device for positioning a surgical instrument, characterised in that it comprises a fixed support (1) combined with at least: a first mobile element (4) articulated on the fixed support (1) about a first axis (H1) substantially parallel to the plane wherein the patient is placed (PP') and capable of carrying out a first movement; a second mobile element (5) articulated at the end of the first element (4) about a second axis (H2) substantially parallel to the plane wherein the patient is placed (PP') and capable of carrying out a second movement; a deformable element (6) fixed on one side to the end of the second mobile element (5) and capable of carrying out a third rotating movement about a third axis (C); a prehensile member (7) fixed on the side opposite to that of the second element to the deformable element; a device (8) for locking a surgical instrument (9) on the prehensile member (7); and actuating means (10 and 11) for producing the rotating movements about the different axes (H1, H2, and C).
