Plasma treatment unit
A plasma treatment unit having a high-voltage stage ( 5, 6 ), arranged in a housing, for generating high-voltage signals suitable for the generation of a plasma, and having a head part ( 2 ) which is connectable to the high-voltage stage ( 5, 6 ) and in which there is situated an electrode arrangement ( 13 ) shielded by a dielectric ( 9 ), is suitable for plasma treatments in particular in the body interior by virtue of the fact that the head part ( 2 ) has an elongate transition piece ( 10 ) which is attachable to the housing and on that end of which which is not connectable to the housing there is arranged a treatment head ( 16, 16 ′), the dimensions of which perpendicular to the longitudinal direction of the transition piece ( 10 ) greatly exceed the dimensions of the transition piece ( 10 ), and that, in the treatment head ( 16, 16 ′), the electrode arrangement ( 13 ) forms a spatially closed flexible sheath ( 12 ) around a resiliently elastic core ( 14 ) and is covered at its outer lateral surface by a thin layer ( 15 ) of the flexible dielectric ( 9 ), such that the treatment head ( 16, 16 ′) can, as it is inserted into a body interior, assume the shape of the surrounding tissue in the body interior.
1. A plasma treatment unit, comprising:
a high-voltage stage arranged in a housing for generating high-voltage signals suitable for the generation of a plasma;
a head part connectable to the high-voltage stage;
an electrode arrangement shielded by a dielectric material located in the head part,
wherein the head part comprises an oblong transition part attachable to the housing,
a treatment head being arranged at an end of the head part which is not connectable to the housing, the treatment head having dimensions perpendicular to a longitudinal direction of the transition part which exceed dimensions of the transition part, and
wherein the electrode arrangement forms a spatially closed flexible envelope around a soft-elastic core and is covered on an outer lateral surface by a thin layer of the flexible dielectric material so that the treatment head, upon insertion into a body interior, assumes a shape of surrounding tissue in the body interior.
2. The plasma treatment unit as claimed in claim 1 , wherein the thin layer of the dielectric material comprises an outer structure which forms free spaces for formation of a plasma upon application to the body interior.
3. The plasma treatment unit as claimed in claim 1 wherein the transition part is flexible.
4. The plasma treatment unit as claimed in claim 1 wherein the transition part the treatment head is wire shaped.
5. The plasma treatment unit as claimed in claim 1 wherein the transition part to the treatment head is tubular in shape.
6. The plasma treatment unit as claimed in claim 1 wherein the housing is formed as a handle part to which the head part is replaceably connectable.
7. The plasma treatment unit as claimed in claim 1 wherein the treatment head is ball shaped.
8. The plasma treatment unit as claimed in claim 1 wherein the treatment head has a truncated cone shape.
