A two-portion device for electromagnetic hyperthermia therapy includes an outer needle, and a first inner needle. The outer needle has an outer body defined an insert space. The outer body has a first magnetic-response portion, and a first nonmagnetic-response portion connected to the top portion of the first magnetic-response portion. The first magnetic-response portion is made of the material could generate heat energy in changed magnetism. The first magnetic-response portion could locate at the lesion portion precisely, and it needs only high frequency magnetism to generate heat energy to ablate the lesion. Therefore, it’s easy to operate the device and the device has low cost. The device also makes small wound and pain alleviating.一種兩段式電磁熱療法治療裝置,包含:一外針,以及一第一內針。該外針包括一個界定出一插設空間的外針本體,該外針本體包括一第一感磁部,以及一連接在該第一感磁部之頂端的第一非感磁部,所述第一感磁部是由可受變化磁場作用而產生熱能之材料製成。該第一內針是可抽出地插設於該外針的插設空間。藉由該外針的兩段式設計,使該第一感磁部可精準地定位於病灶部位,而且只需要藉由高頻磁場作用即可發熱而燒灼病灶,使本發明具有操作簡單、治療方便、成本低,並且對患者造成之傷口較小,治療過程之痛苦程度亦較低。2...外針20...插設空間21...外針本體211...第一感磁部212...第一非感磁部3...第一內針
