Claims

Claims

1. Surgical device (10) comprising: - a hollow guide tube (100) extending longitudinally between a proximal end and a distal end, - a surgical tool (300) connected to the distal end of the guide tube, - a mechanical connecting means (700) of the braided torque coil type comprising at least one wire, said means being disposed between and connecting the guide tube and the surgical tool, - orientation means connected to the mechanical connecting means arranged to impose a mechanical constraint so as to orient the tool in a desired direction.

2. Device according to the preceding claim in which the orientation means comprise orientation cables (500) and control means (400) equipped with servomotors.

3. Device according to one of the preceding claims, further comprising means for actuating the tool comprising at least one tool cable (600).

4. Device according to one of the preceding claims, in which the mechanical connecting means (700) comprises at least two radially superimposed coil layers, preferably three radially superimposed coil layers.

5. Device according to one of the preceding claims, in which the guide tube has an external diameter of less than 3 mm, advantageously less than 2.5 mm, even more advantageously less than 2 mm.

6. Device according to one of the preceding claims, comprising only a mechanical connecting means of the braided torque coil type between the surgical tool and the guide tube.

7. Device according to one of claims 1 to 5, further comprising an elastically deformable connecting element (200), preferably in one piece, preferably capable of bending under the effect of mechanical stress, and secured to the guide tube by a proximal end of said element.

8. Device according to one of the preceding claims, in which the surgical tool is a surgical micro-forcep.

9. Assembly comprising a surgical device according to one of the preceding claims and a laser device for ablation of tissues of a individual.
