Abstract: The plasma sensor monitors parameters characterizing the condition of the plasma during the treatment phase and/or the change thereof in order to recognize a prefiguring or already occurred interruption of the plasma in this manner and to avoid this interruption and, in the ideal case, avoid this by already changing the voltage form previously. The mentioned mechanisms can be used by the control device (22) also during a pulse packet. The length of each pulse packet is adapted at each change of the voltage form according to their characteristics in order to guarantee a constant average power.

Abstract: Devices and methods for image-based treatment with an instrument configured to apply variable amounts of treatment medium at different locations. Devices having an image caption device that is configured to capture the area to be treated. The device comprises an evaluation device that is configured to determine a treatment trace of the treatment medium relative to the area to be treated from data of the image capture device and to determine a spatially resolved dosage for the area to be treated based on the treatment trace. Devices having a representation device that is configured to display the treatment trace and/or the spatially resolved dosage optically for a user, relative to the tissue. Methods to optically indicate the locations of the area to be treated of the tissue surface that have already been treated and/or the dosage with which the respective treated locations have been treated.

Abstract: A plasma for prevention of intraepithelial neoplasia, particularly by anti-viral therapy. The plasma may be used, for example, against the human papillomavirus, for treatment of intraepithelial neoplasia of all grades of severity, e.g., carcinoma in situ lesions, and/or for treatment of invasive carcinoma that is reachable in epithelial manner. A system for creating the plasma includes a medical instrument with at least one electrode having galvanic contact to the plasma. The medical instrument also has an RF device that provides an alternating voltage to supply the instrument with electric power and a gas supply device that is adjusted to supply gas, for example argon gas, to the instrument.

Abstract: To provide the user of an RF-surgical instrument with a non-hazardous short test operation, for example so as to test the ignitability of an argon plasma probe, provision is made for an instrument test arrangement, which is installed into a feeding medical device or into a neutral conductor connecting cable or which is provided as plug adapter, which is to be plugged between the device and the neutral conductor connecting cable. The instrument test arrangement comprises at least one or, better yet, two ignition test electrodes, which are connected to conductors of the device or of the neutral conductor cable, preferably via impedance components. The ignition test electrodes can be accessed insofar as a spark can be created simultaneously to both ignition test electrodes by means of an operational probe or an instrument.

Abstract: An instrument test arrangement is specified, which is preferably equipped for medical instruments for argon plasma coagulation. The instrument test arrangement comprises an electrode arrangement, comprising at least one test electrode. In a preferred embodiment, a test electrode is thereby connected to two neutral conductors of a neutral conductor cable or device, wherein the neutral conductors are insulated from one another, and wherein the first coupling impedance between the test electrode and the first neutral conductor and the second coupling impedance between the test electrode and the second neutral conductor are equal or at most slightly different, so that a split circuit, which is assigned to a neutral electrode arrangement, does not trigger due to the strike of a test spark or arc.

Abstract: An anti carbonization device to prevent the carbonization of tissue upon plasma coagulation by a suitable surgical instrument, wherein the surgical instrument has a feed line for an oxidizing agent, a feed line for a gas and an electrode for generating a plasma. A gas-oxidizing agent mixture for generating a gas oxidizing agent plasma is provided by the anti-carbonization device.
