To provide a high-frequency thermal therapy apparatus and an electrode replacement aid capable of easily performing a replacement work of a disc electrode.A high-frequency thermotherapy apparatus 1 includes a pair of electrode shafts 34, 35 arranged to face each other, a pair of disc electrodes 37, 37 which are detachably attached to the pair of electrode shafts 34, 35 and face each other with the affected part 101 interposed therebetween , 47. A high frequency electric power is applied between the pair of disc electrodes 37, 47 to thermally treat the affected part 101 by dielectric heating, and the electrode attachment 36 including the disc electrode 37 etc etc. is inserted into the electrode shaft 34 etc. , And an arm mechanism 72 as a moving mechanism for moving the placing plate 71. The arm mechanism 72 moves the placing plate 71 in a state where the placing plate 71 is supported by the arm mechanism 72. As shown in FIG.(FIG.【課題】円盤電極の交換作業を容易に行うことができる高周波温熱治療装置及び電極交換用補助具を提供する。【解決手段】高周波温熱治療装置1は、対向配置される一対の電極軸34,35と、一対の電極軸34,35に着脱可能に装着されて患部101を挟んで対向する一対の円盤電極37,47とを備え、一対の円盤電極37,47間に高周波電力を印加し、誘電加熱によって患部101を温熱治療するものであって、円盤電極37等を含む電極アタッチメント36等を電極軸34等から取り外した状態で支持する支持部としての載置板71と、載置板71を移動させる移動機構としてのアーム機構72と、を備えている。【選択図】図4
