DEVICE FOR COAGULATION OF TISSUES

摘要

1. Device for the coagulation of tissues, containing, wired in series, a high voltage electricity supply source, an effective power regulator and a probe, characterised in that it has a piezo-electric voltage transformer, the power input of which is connected to the said effective power regulator and the controlling input to a constant voltage source, while the output is connected to the probe. 2. Process for the electrical coagulation of tissues using the device described in claim 1, in which at the beginning of the coagulation process, the resonance frequency of the piezo-electric transformer is displaced towards the side of lower frequency values, thus reducing the effective power by an extent sufficient to exclude the influence of trembling of the surgeon's hands on the operation of the device. 3. Process in accordance with claim 2, characterised in that the displacement of the resonance frequency is implemented to a magnitude of 0.5-0.6%.
