A radio frequency ablation method, system, storage medium and intelligent terminal

Abstract

The present application relates to a radio frequency ablation method, system, storage medium and intelligent terminal, and relates to the field of medical devices. The method includes obtaining current treatment area information; determining expansion range information; determining advancing distance information; extending the radio frequency central electrode into the treatment area The radio frequency sub-electrodes are expanded according to the propulsion distance information; the electrode temperature information and cell temperature information are obtained; the temperature difference information is calculated; the current current power information is determined; Output power and increase the temperature of the radio frequency central electrode and the radio frequency sub-electrode to ablate the cancerous cells in the treatment area, which improves the problem that the temperature rise process is faster and the treatment range is small. This application has increased the treatment range, By controlling the temperature change, the ablated cancerous cells are less likely to be charred, thereby improving the therapeutic effect.

Description

technical field [0001] The present application relates to the field of medical devices, and in particular, to a radio frequency ablation method, system, storage medium and intelligent terminal. Background technique [0002] With the development of modern medical technology, minimally invasive treatment has become the most promising technology in the field of tumor treatment. At present, for local solid tumors such as liver cancer and lung cancer, the tumor minimally invasive treatment technology represented by radiofrequency ablation is playing an increasingly important role in the field of minimally invasive treatment. [0003] The principle of radiofrequency ablation is to apply alternating high-frequency current with a frequency of less than 30MHz (usually 460-480kHz) to cause high-speed oscillation of ions in tumor tissue, friction with each other, and convert radiofrequency energy into heat energy, causing coagulation necrosis of tumor cells. In radiofrequency ablation...
