Abstract

The invention discloses a radio frequency ablation system and a control method thereof. The radio frequency ablation system comprises a radio frequency ablatograph for generating radio frequency energy on the basis of set ablation parameters, and a plurality of bipolar radio frequency ablation needles, wherein each bipolar radio frequency ablation needle comprises a first electrode and a second electrode for outputting the radio frequency energy; the radio frequency ablatograph comprises a radio frequency energy generator and a switching circuit; the radio frequency energy generator is used for generating radio frequency energy; the switching circuit is used for controlling the on-off states between each first electrode, each second electrode and the radio frequency energy generator. According to the technical scheme, the on-off states between each first electrode, each second electrode and the radio frequency energy generator can be independently controlled through the switching circuit, the size of the radial ablation region can be obtained through one first electrode and one second electrode, and the shape of the ablation region can be accurately controlled by controlling the on-off states of each first electrode and each second electrode.

Description

technical field [0001] The present invention relates to the technical field of medical surgical instruments, and more specifically, relates to a radio frequency ablation system and a control method thereof. Background technique [0002] At present, the treatment methods for minimally invasive nerve treatment mostly use radiofrequency ablation technology, which generates radiofrequency energy with a frequency of 375KHz-500KHz through the radiofrequency generator, and transmits the radiofrequency energy to the surgical electrode. Molecular vibration and friction of the tissue around the surgical electrode generate heat. When the temperature of the lesion tissue exceeds 60°C for 3-4 minutes, the lesion tissue will undergo irreversible necrosis, thereby achieving the therapeutic effect. [0003] Generally, the lesion area to be ablated is multi-spherical. For radiofrequency ablation, the theoretical result of the ablation area should also be spherical. However, because the blood...
