  • Patent number: 11185365
    Abstract: High-frequency (HF) tools are used in medicine for manipulating body tissue, using an HF resectoscope. For electrical insulation of an electrode from an electrode support, the ends of the electrode are initially guided through ceramic tubes. These ceramic tubes are sensitive in particular to forces transverse to the longitudinal axis of the resectoscope. Disclosed herein is a high-frequency tool that has increased stability with respect to transverse forces. An electrode has two ends, which for establishing a connection to an electrode support are each insertable into a receiving opening of the ends of the electrode support, or positionable in front of the ends. The electrode is contacted in an electrically conductive manner, at least in the area of a receiving opening, with a conductor wire that is guided in the electrode support.

  • Patent number: 11154352
    Abstract: Apparatus, consisting of a probe with a temperature sensor and a transducer in contact with a living subject's tissue. A power supply delivers electrical power to the transducer for tissue ablation. A controller receives a signal from the temperature sensor and in response outputs a tissue temperature. During a first time period the power supply delivers no more than a first target power to the transducer, and reduces the power when a first maximum allowable temperature of the tissue is exceeded. During a transition time period the power supply delivers no more than a second target power, while reducing the delivered power when the first maximum allowable temperature of the tissue is exceeded. During a second time period the power supply delivers no more than the second target power, while reducing the delivered power when a second maximum allowable temperature, less than the first maximum allowable temperature, is exceeded.
