- high frequency energy radiation is generated between adjacent electrodes and electrodes at pitch P intervals, thereby forming a high frequency energy radiation region in a cylindrical shape as a whole. Therefore, the two electrode bodies 13 and 15 generate frictional heat by causing ions of the lesion tissue to vibrate by the energy generated in the radiation zone, thereby raising the temperature of the lesion tissue by the heat, thereby causing the lesion.
- the site can be effectively treated to a minimum thickness, i.e. without damaging other adjacent tissues, by a cylindrical radiation zone that follows the shape of the lesion site.
- MRI computed tomography
- MRI magnetic resonance
- the human body that predicts the path before insertion of the electrode through the position sensor on the handle part during the thermal treatment (RFA) procedure, and displays the path to accurately position the electrode needle after insertion through the position sensor on the electrode part.
- An insertion electrode position sensing device and method can be realized.
- the present invention is to predict the path before the insertion of the electrode through the position sensor of the handle portion in the electrode device for high-frequency heat treatment, and to display the path so that the electrode needle is accurately positioned on the lesion after insertion of the human body through the position sensor of the electrode needle portion It can be applied to the human body insertion electrode position sensing device and method.
