Abstract

This invention provides a cutting tool, comprising a sleeve enclosing a suction chamber where, during use, a reduced pressure prevails and wherein a cutting member is arranged so as to be movable along a suction opening provided in the wall of the sleeve. The wall of the sleeve forms a light conductor. The sleeve can be tubular and is preferably manufactured from light conduction material, in particular glass.

Claims (16)

1. A cutting tool comprising a sleeve enclosing a suction chamber where, during use, a reduced pressure prevails and wherein a cutting member is arranged so as to be movable along a suction opening formed in the wall of the sleeve, characterized in that the wall of the sleeve forms a light conductor.

2. A cutting tool according to claim 1 , wherein the sleeve comprises a tube part with a cutting opening formed adjacent one extremity of the tube part in the tube wall and wherein the tube channel enclosed by the tube wall forms the suction chamber.

3. A cutting tool according to claim 1 , wherein the cutting member comprises an inner tube included in the tube channel so as to be coaxially moveable, the inner tube channel of the inner tube being connected to a suction duct during use.

4. A cutting tool according to claim 3 , wherein tube and inner tube are designed as capillaries.

5. A cutting tool according to claim 1 , wherein the sleeve is manufactured at least partly from light conducting material.

6. A cutting tool according to claim 1 , wherein the sleeve is provided with a light exit window located adjacent the cutting opening.

7. A cutting tool according to claim 6 , wherein the light exit window is designed as a lens.

8. A cutting tool according to claim 1 , wherein the inner and/or outer wall of the tube is provided, at least partly, with a covering which prevents exit of light from the sleeve.

9. A cutting tool according to claim 8 , wherein the covering is formed by a reflective coating for reflecting exiting light back into the tube wall.

10. A cutting tool according to claim 8 , wherein the covering is formed by a refractive structure of the surface of the tube wall for reflecting exiting light back.

11. A cutting tool according to claim 8 , wherein the covering is formed by a further tube part provided against the inner and/or outer wall of the light conducting sleeve.

12. A cutting tool according to claim 1 , wherein the sleeve is included in a handle.

13. A cutting tool according to claim 1 , wherein in the handle, a movement mechanism is accommodated for moving the cutting member along the suction opening provided in the wall of the sleeve.

14. A cutting tool according to claim 12 , wherein the handle is provided with a connecting plug four connection of the suction duct, which plug is in communication with the suction chamber.

15. A cutting tool according to claim 12 , wherein the handle is provided with a connection which is in light conducting communication with the sleeve for the connection of a flexible light conductor.

16. A cutting tool according to claim 5 , wherein the light conducting material is glass.
