The invention discloses a high-voltage transmitting circuit for a catheter and an ablation tool. The catheter is provided with a plurality of first electrodes and a plurality of second electrodes. The high-voltage transmitting circuit comprises a first transmitting circuit, a second transmitting circuit, a first switching circuit, a second switching circuit and a control circuit. The first transmitting circuit is connected with the plurality of first electrodes through the first switching circuit; the second transmitting circuit is connected with the plurality of second electrodes through the second switching circuit; the control circuit controls the first transmitting circuit, the second transmitting circuit, the first switching circuit and the second switching circuit so that positive high voltage, negative high voltage, zero voltage or multiple high voltage can be formed between any first electrode and any second electrode. Therefore, the pulse voltage between any two transmitting electrodes is flexibly adjusted by controlling the on-off between the transmitting circuit and the transmitting electrodes, the treatment requirements in various pulse electric field ablation operations are met, and the application prospect of the pulse electric field ablation technology in arrhythmia treatment is improved to a great extent.
Description
technical field [0001] The invention relates to the technical field of pulse electric field ablation, in particular to a high-voltage transmitting circuit and an ablation tool for a catheter. Background technique [0002] At present, the ablation energy in the catheter ablation technology used in the treatment of arrhythmia is usually mainly radiofrequency energy, supplemented by cryoenergy. These two ablation methods have shown certain advantages in the treatment of arrhythmia, but also have corresponding limitations. For example, the ablation energy lacks selectivity in destroying the tissue in the ablation area, and depends on the adhering force of the catheter, which may cause certain damage to the adjacent esophagus, coronary artery, and phrenic nerve. Therefore, it is necessary to find a fast, safe and efficient ablation energy To complete and achieve persistent pulmonary vein isolation and not to damage the related technology of adjacent tissue has become a research h...
