APPARATUS AND METHOD FOR GENERATING PLASMA IN AQUEOUS ENVIRONMENT

摘要

To provide an apparatus that allows ignition and stable development of plasma on an electrode of an instrument.SOLUTION: An apparatus (14) for supplying a medical instrument (15) for treatment of biological tissue (11) by the action of plasma (28) is disposed, in accordance with the invention, in a special manner for ignition and stable development of the plasma (28) on an electrode (27) of the instrument (15). To accomplish this, the apparatus (14) comprises a control device (23) that, during an ignition test, limits, preferably in an instrument-specific manner, the current deliverable to the instrument (15) and/or the electrical power to be output to the instrument (15), and, in doing so, works with a reduced operating voltage. With this measure, rapid and stable plasma development with minimal spark play is achieved with a large variety of connectable instruments (15a-15e).SELECTED DRAWING: Figure 1
