What is the radiofrequency needle ablation of liver cancer?

Radiofrequency needle ablation for liver cancer is a new minimally invasive method and new technology that develops rapidly in China. It is guided by CT or ultrasound to accurately locate liver cancer lesions, and then radiofrequency ablation needle is inserted into the core of liver cancer. The whole procedure is performed by an interventional radiologist or an interventional ultrasound physician. Because of the radiofrequency ablation process, there is a certain amount of pain. A propofol intravenous anesthetic is usually administered by an anesthesiologist. Radiofrequency ablation technology is to insert the radiofrequency ablation needle into the core of the tumor, extend multiple electrode wires from the front end of the radiofrequency needle to the tumor tissue, and then through the output of radiofrequency current, the cell ions in the lesion area can shock and friction to generate heat, and the local temperature within the lesion can reach more than 90 degrees. Through the radiofrequency technology heating, the liver cancer tumor tissue can be killed, so that the tumor tissue solidification necrosis, so as to achieve the purpose of liver cancer treatment.
