The invention provides a surgical device for osteotomy allowing accurate determination of the angle at which a bone in the human or animal body should be corrected, and for precisely maintaining said angle constant during the entire surgical procedure. The surgical device comprises on its distal end a circular segment (D) fixed to a distal end of a first blade (&Agr;') and further moveably connected to a distal end of a second blade (A), allowing to move said distal end of the second blade along the circular segment, wherein the proximal ends of the first (&Agr;') and second blade (A) converge at an angle, and at least a pair (I and II, or III and IIIl) of pin guide openings provided in parallel for inserting and positioning at least two parallel pins or drill bits (T, T'). The surgical device provides unique fixed reference means allowing to perform a precise surgery according to the predetermined parameters and angles even at the final stages of the operation. |
