Problems solved by technology
Therefore, at one end of the coil, the danger of arcing between the coils will not be exempted
The risk of flashover is also increased by the user creating additional capacitance; wherein the additional capacitance will disturb the resonant circuit consisting of the secondary coil and the capacitance associated with this secondary coil, thereby causing Easier arcing between coils
If the primary coil and the secondary coil have different lengths, for example in the subject matter of DE 36 18 412 A1 and WO 2006 / 1199971 A1, in combination Figure 1a and Figure 1b It can also be seen more clearly that the danger will increase again

Embodiment Construction
[0067] exist figure 2 , image 3 as well as Figure 4a Different elements of an apparatus for treating biological tissue by low-pressure plasma according to an embodiment of the present invention are shown in to q and will be explained in more detail subsequently.
[0068] figure 2 For example, an embodiment of a transformer chamber 8 of a device according to the invention is shown. A transformer is installed in the transformer chamber 8 . The transformer consists of a primary coil 4 and a secondary coil 5 . The control device 3 is connected to the transformer via a coupling 9 . Wherein, the control device 3 is further connected with a power source 13 (not shown) for providing power to the transformer 1 . The probe 2 , in particular a glass probe, is arranged on the coupling 7 . The coupling element 7 is in turn arranged at the end of the transformer chamber 8 opposite the coupling element 9 . In this case, the contact spring 12 ensures that there is always electrica...

The invention relates to a device for the treatment of biological tissue (G) by means of a low-pressure plasma, comprising: a transformer (1) for producing a high-frequency electromagnetic field; a probe electrically coupled to said transformer (1); and a control device (3), used to control the high-frequency electromagnetic field generated by the transformer (1); wherein, the transformer (1) has a primary coil (4) and a secondary coaxially arranged with the primary coil (4) coil (5); wherein, in the overlapping region (8) of the two coils (4, 5), the intermediate distance between the primary coil (4) and the secondary coil (5) is within the distance between the probe The direction of the coupling (7) of (2) increases from a first distance (d1) to a second greater distance (d2).
Description
technical field [0001] The invention relates to a device and a method for treating biological tissue by means of a low-pressure plasma (plasma) according to the preamble of claim 1 . The invention further relates to a method for treating biological tissue by means of a low-pressure plasma. Background technique [0002] Plasma is known to have antimicrobial properties. The antimicrobial effect of plasma is caused by heat, dehydration, shear stress, UV radiation, free radicals, and electrical charges. In the case of low-pressure plasmas (also known as cool plasmas), since these plasmas operate at room temperature, heat plays only a secondary role. In such low-pressure plasmas reactive particles are especially produced, which have a sufficiently long lifetime to destroy tissue compounds through indirect exposure; wherein these reactive particles are for example different oxygen- or nitrogen-containing species . These particles inter alia include oxygen atoms, superoxide rad...
