Description

technical field [0001] The invention relates to the technical field of radio frequency ablation, in particular to a multi-channel radio frequency output circuit and an ablation device. Background technique [0002] At present, in minimally invasive surgery, radiofrequency technology has been widely used in the treatment of many diseases. Radiofrequency technology generates sine waves with a frequency between 300Khz and 1000Khz. The radiofrequency energy generated by the sine waves is applied to the lesion that needs to be treated through radiofrequency catheters or radiofrequency electrodes, so that it can block or regulate, and then achieve treatment. Effect. [0003] For example, in the field of pain treatment, radiofrequency ablation equipment often uses unipolar or bipolar methods to perform radiofrequency ablation operations. First, the focus is identified through the stimulation signal, and then the focus is treated with radiofrequency signals. Wherein, adopting the ...

Problems solved by technology

[0004] Therefore, in the field of pain treatment, no matter whether the radiofrequency ablation device adopts the monopolar method or the bipolar method, it can only form a single circuit to realize the output of radiofrequency energy, which will lead to longer operation time of radiofrequency ablation treatment and is difficult to guarantee Ablation effect
