Radiofrequency ablation is the most classic local ablation technique, with extensive applications and adequate clinical research.
This technique is recommended by a variety of domestic and foreign guidelines, such as NCCN, CSCO, etc. It is mainly used in the local treatment of various solid tumors, including the radical treatment of early-stage tumors and the palliative treatment of advanced tumors.
Puncture the radiofrequency electrode to the target under the guidance of ultrasound, CT or MRI, and the 480KHz alternating current will be sent out through the radio frequency generator, so that the ions around the needle tip oscillate at high frequency and generate heat by friction, then the local temperature rapidly rises to 90℃ Above, to achieve the purpose of coagulation necrosis of diseased tissue.
The Radiofrequency electrodes are intended for percutaneous puncturing, laparoscopic surgeries and open surgeries. They can be used under the guidance of medical images such as ultrasound and CT.
