Background

Chinese patent document CN 112568890A describes a minimally invasive multi-electrode bioelectrical impedance detection system and detection method, in which it is described that the accuracy of radio frequency detection can be greatly improved by invasive electrodes. Through clinical examination, the detection rate of minimally invasive radio frequency detection on abnormal tissues exceeds 95%. I.e. the impedance, the capacitive reactance of normal tissue and their combined data, are clearly different from the impedance, the capacitive reactance of abnormal tissue, e.g. tumor tissue, and their combined data. However, no electrode special for minimally invasive detection exists at present, and an electrode needle is used for sampling clinically, so that the electrode is inconvenient to use.
