- the tracer (1) object of the invention marks the planned distance (D) at which the osteotomy is performed offering a control of the movements made by the surgical handpiece (15) used in performing the osteotomy with those movements being limited to movements within the planned distance (D) with respect to the support point but allowing the movement of the tracer handpiece assembly (15-1), longitudinally thus performing the osteotomy, resulting in a cut in the bone of a length defined and at a planned distance (D).
- the plotter (1) object of the invention (observable in Figures 1, 2 and 3) comprises guide wire (2) connected to an interchangeable head (3).
- Head interchangeable (observable in Figure 4) has different dimensions depending on the planned distance "D" at which you want to perform the osteotomy, so that osteotomies can be performed at different planned distances (D) by simply changing the head (3 ) interchangeable in the plotter (1) object of the invention.
- the tracer (1) object of the invention is coupled to any surgical handpiece (15) by means of clamps (14) that fix the surgical handpiece (15) and the guide wire (2) of the tracer (1) together. ), avoiding relative movements between them.
- the interchangeable head (3) (observable in figure 4) comprises:
- a central body (9) which in turn comprises a groove (10) through which a cutting element (16) of the surgical handpiece (15) that performs the osteotomy is introduced;
- the planned distance (D) marked by the tracer in performing osteotomy is determined by the interchangeable head (3) of the tracer (1), and within the interchangeable head (3) the planned distance (D) is the distance between the opposite face of the support element (1 1) that carries out the support at the patient's reference point (bone or gum) and the groove (10) of the central body (9).
- the central body (9) (observable in figures 5 and 6) is a flat piece with a polygonal shape with curved sides, comprising a first recess (12) in which the support element (1 1) and a second one are fixed recess (13) in which the connector (5) is fixed.
