摘要： A bipolar instrument and a method for endoscopically controlled shortening and/or fragmentation of a stent located in the gastrointestinal tract, in the tracheobronchial system or in other hollow organs. The instrument includes a first electrode and a second electrode arranged at a distal end of the instrument and connected to and receiving current provided by a power source, and protective means connected to the electrode means. At least one wire of the stent can be severed at a particular location by the instrument. The protective means separates the wire from tissue of the gastrointestinal tract, tracheobronchial system or other hollow organs and/or secures the wire to the instrument during the severing of the wire. The instrument and the method minimize damage to tissue and risk to the patient during machining of stents.

摘要： A device for devitalizing biological tissue and a method for controlling a device for devitalizing biological tissue. According to one embodiment, at the start of the devitalization, a low, first temperature is used and, at the end of the devitalization, an increased, second temperature is used. A device and method for operating a cooled HF (high frequency) ablation probe, wherein the temperature of the probe is primarily regulated via the cooling power supplied to the probe, is also described. According to another embodiment, the HF energy supply to the probe during treatment of a tissue region is operated first at a constant current and then at a constant voltage.

摘要： A method and a measurement apparatus are provided for determining the transition impedance between two electrode parts of a subdivided neutral electrode used in high-frequency surgery. These makes it possible for the purely capacitive component of the transition impedance to be measured. For this purpose a resonant-frequency shift is measured, which occurs when a basic resonant circuit is expanded to an expanded resonant circuit by incorporating the two electrode parts into it in parallel. In particular, in order to determine the basic resonant frequency of the basic resonant circuit and/or the sample resonant frequency of the expanded resonant circuit, the phase shift between current and voltage is measured and the frequency is adjusted until current and voltage are in phase.

摘要： The invention relates to a high-frequency surgical device for monopolar coagulation of biological tissue using a high-frequency current. The device includes an electrosurgical instrument with a coagulation electrode and a surgical device with a high-frequency generator for generating a high-frequency voltage and for supplying the high-frequency current to the coagulation electrode of the electrosurgical instrument and at least one control device for terminating the coagulation process. A measuring device detects at least one measured value describing a measured tissue introduction of energy into a defined measured tissue area. An arithmetic device determines the measured tissue introduction of energy into the defined measured tissue area and a final value for a target tissue introduction of energy into a target tissue area. The control device regulates the high-frequency generator based on the final value by generating a shut-down signal when the target tissue introduction of energy reaches the final value.

The RF surgical apparatus comprises at least two RF generators and at least one neutral electrode output for one neutral electrode. At least two outputs for connecting RF surgical instruments for applying treatment currents to the surgical instruments are provided. Furthermore, a switching device is provided.

摘要： An apparatus for the interstitial coagulation of tissues includes at least one electrode by way of which an HF coagulation current can be conducted into the tissue of a patient. The electrode is constructed as a three-dimensional body that can be expanded to various states of expansion, or is attached to such a body, so that by continuous or stepwise expansion of the body the electrode can be kept in constant electrical contact with the tissue during coagulation. In this way the apparatus enables the tissue treatment to be more uniformly distributed.
