Micro-needle head for treating tissue by radio-frequency electrical impulses

摘要

A micro-needle head for treating tissue with radiofrequency electric pulses, at the front of which are located at least two groups of electromagnetically (5) or other mechanism-extending electrically insulated needles (8) disposed in a nut in the exchange part (7). At one time only one group of needles (8) are connected to the output of the high-frequency current generator, which do not interact with each other electrically and therefore no current merging and the effect of the applied energy acting just and only at one particular point under the tips of the needles (8) groups.
