The regulating system comprises a signal acquisition module, a signal processing module, an amplifier module, a display module, a power selection module and an ablation electrode, wherein the signal acquisition module is used for acquiring an impedance signal of a heart, the impedance signal is amplified by virtue of the amplifier module and is transmitted to the signal processing module, the signal processing module is used for processing and calculating the signal so as to obtain impedance information, and the power selection module is used for selecting working power of the ablation electrode according to a processing result of the signal processing module; and the display module is used for displaying a heart impedance result and the working power of the ablation electrode, and the ablation electrode is used for carrying out ablation treatment on a heart region. The regulating system disclosed by the invention can detect impedance of a focus region in real time, judge an impedance value and carry out ablation on the focus region, so that the aim of continuous ablation of the radio frequency catheter is achieved, and a treatment effect is improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an adjustment system for an arrhythmia radio frequency catheter. Background technique [0002] With the development of biomedicine, the use of radiofrequency catheter technology to treat arrhythmia has been widely used. Radiofrequency catheter treatment of arrhythmia is through 300-1000 kHz high-frequency sinusoidal alternating current radiofrequency energy to ablate and block the most critical parts that cause arrhythmia, so as to cure arrhythmia. The radio frequency catheter generates radio frequency current, which causes high-speed ion vibration and friction in the surrounding tissue, which is converted into heat energy, causing thermal coagulation necrosis and denaturation of local tissue cells. From a pathological point of view, when the temperature reaches above 60 degrees, the Proteins will change their characteristics due to heat, resulting in irrev...
