Abstract

An instrument for performing liposuction with a longitudinally extended rod-shaped part that, at its rear end, has a handle and a front end piece for partially introducing the rod-shaped part under the skin at a site to be treated. The rod-shaped part is, at least over a portion of its length, provided with a roughened surface. This enables the rod-shaped part to be partially introduced under the skin at the site that has already been treated with a suction instrument. At this location, the rod-shaped part can, with its roughened surface, simultaneously distribute the remaining fatty layer remnants or to remove these remnants from the remaining tissue by means of a to-and-fro movement in the longitudinal direction.

Claims

1. An instrument for performing liposuction on a fat layer located under a surface of skin of a location to be treated, said instrument comprising:

an elongated rod-shaped part made of elastically bendable stainless steel, having a rounded cross-section, said elongated rod-shaped part including;

a rear-end portion; and

a front-end portion having a front-end tip portion which forms a front-end of said instrument, said front-end portion and said front-end tip portion having a roughened surface continuously extending to the front-end of said instrument, said front-end tip portion having (i) rounded side portions formed by said roughened surface which continuously extends to the front-end of said instrument, and (ii) a non-rounded and flat downwardly angled upper surface and a non-rounded and flat upwardly angled lower surface which both extend to meet and form a rounded front edge, said rounded front edge having a rounded cross-section formed by said rounded side portions and said non-rounded and flat upper and lower surfaces, and said rounded front edge extending across a width of said non-rounded and flat upper and lower surfaces and extending between said rounded side portions; and

a handle connected to said rear-end portion of said elongated rod-shaped part,

wherein said front-end tip portion, said front-end portion, and said roughened surface are operable to be inserted and move backwards and forwards under and along the surface of the skin of the location to be treated so as to treat the fat layer with said roughened surface.

2. The instrument according to claim 1, wherein said handle includes a reference surface positioned to indicate an orientation of said rounded front edge.

3. The instrument according to claim 1, wherein said instrument is operable to be inserted under the skin alternately with a suction instrument.

4. The instrument according to claim 1, wherein said elongated rod-shaped part is formed to have a round, oval, or rounded edge cross-section.

5. The instrument according to claim 2, wherein said elongated rod-shaped part is formed have a round, oval, or rounded edge cross-section.

6. The instrument according to claim 3, wherein said elongated rod-shaped part is formed to have a round, oval, or rounded edge cross-section.

7. The instrument according to claim 1 wherein:

said non-rounded and flat downwardly angled upper surface is a non-roughened surface;

said non-rounded and flat upwardly angled lower surface is a non-roughened surface; and

said rounded front edge is a non-roughened edge.

8. The instrument according to claim 1, wherein said rounded front edge is non-circular.
