Abstract

The invention relates to a device for collecting small diameter hair grafts comprising a portable cutting tool (1) which is consists of a tool-holder body (2), a cylindrical tool provided with a hollow axle (4) for inserting hollow needle (5, 17, 25) whose diameter ranges from 0.7 to 2 mm, a motor (3) for rotatably driving said needle (5, 17, 25) with respect to said body (2). The inventive device also comprises a graft storage container (9, 18, 22) which is connected to the body (2) and is provided with a graft input orifice (10, 19) connected to the vicinity of the rear end of the hollow needle (5, 17, 25) and a suction orifice (13, 20) connected to graft suction means which is arranged in such a way that the graft is enable to enter directly the container (9, 18, 22) by sucking said graft through the needle (5, 17, 25).

Claims

1. Device to remove small hair grafts comprising a portable cutting instrument (1), the instrument comprising:

a tool-rest body (2);

a cylindrical tool with a hollow axis (4) in the body, a hollow needle (5, 17, 25) having a diameter which ranges from 0.7 mm to 2 mm, the needle being inserted in the hollow axis;

a motor (3) able to drive the needle (5, 17, 25) in rotation with respect to the body (2);

a storage tank (9, 18, 22) for grafts integral with the body (2), the tank (9, 18, 22) comprising an inlet (10, 19) for grafts connected near a rear end of the hollow needle (5, 17, 25) and a suction opening (13, 20) means for supplying graft suction being connected to the suction opening, the means of suction being fitted to enable the graft to directly reach the tank (9, 18, 22) by suction of the graft through the needle (5, 17, 25).

2. Device according to claim 1, characterised in that the tool-rest body (2) is a roughly cylindrical handpiece.

3. Device according to claim 1, characterised in that the tool-rest body (2) is a contra-angle handpiece.

4. Device according to claim 1, characterised in that the tank is integral with the body (2) by a flexible pipe (23) whose length does not exceed the length of the body (2).

5. Device according to claim 1, characterised in that the tank (9, 18, 22) is impermeably connected to the body (2).

6. Device according to claim 1, characterised in that the hollow needle (5, 17, 25) is detachable with respect to the body (2).

7. Device according to claim 1, characterised in that the storage tank (9, 18, 22) comprises a filter (30), the filter extending along the entire transverse section of the tank, near the suction opening (13, 20).

8. Device according to claim 1, characterised in that the tank (9, 18, 22) also comprises an inlet (26) for a graft preservation solution, the inlet being connected to a supply pipe (27) for preservation solution.

9. Device according to claim 8, characterised in that the preservation solution comprises isotonic solution.

10. Device according to any of claims 1 to 9, characterised in that the walls of the storage tank (9, 18, 22) are transparent.

11. Device according to claim 7, characterised in that the tank (9, 18, 22) also comprises an inlet (26) for a graft preservation solution, the inlet being connected to a supply pipe (27) for preservation solution.
