DEVICE AND METHOD FOR CREATING PLASMA IN AN AQUEOUS ENVIRONMENT

摘要

A device (14) for supplying a medical instrument (15) for the treatment of biological tissue (11) by the action of a plasma (28) is according to the invention in a special way to the ignition and the stable construction of a plasma (28) on the electrode (27 ) of the instrument (15). For this purpose, the device (14) has a control device (23) which limits the current to be supplied to the instrument (15) and / or limits the electric power to be delivered to the instrument (15) during and / or during the ignition test reduced operating voltage works. With this measure, for a large variety of connectable instruments (15a-15e), respectively, a fast, stable plasma structure with a low spark gap is achieved.
