Abstract The disclosed electrode device for high frequency thermotherapy apparatus comprises a base member; a cavity-inserted cylindrical body removably fixed to the base member and inserted into a cavity of a living body; a separator fixed to the base member and arranged in the cylindrical body, for partitioning a space within the cylindrical body into two; an electrode arranged at an end of the separator; and in particular a circulation passage for a cooling liquid being formed extending from a going path, through an end space, to a return path within the cylindrical body. Therefore, the surface of the living body in contact with the cylindrical body can be efficiently cooled by circulating a cooling liquid therethrough to protect the surface of the living body from being heated excessively. Further, the cavity-inserted cylindrical body can be replaced or removed for washing to realize a sanitary medical treatment.
An electrode device for high frequency thermotherapy apparatus, comprising; (a) a base member having a cooling liquid charge port and a cooling liquid discharge port; (b) a cavity-inserted cylindrical body removably fixed to said base member under liquid-tight conditions; (c) a separator fixed to said base member and arranged in said cavity-inserted cylindrical body along the longitudinal direction thereof, partitioning a space within said cavity-inserted cylindrical body into a first and a second space except for an end space thereof, said first space communicating with said charge port and said second space communicating with said discharge port, said separator comprising a flat liquid passage partition plate having a width substantially equal to an inner diameter of said cavity-inserted cylindrical body coupled to a flat liquid charge/discharge partition plate fixed to said base member having a width substantially equal to an inner diameter of said base member; (d) an electrode arranged at one of said separator extending into said end space; and (e) a circulation passage for a cooling liquid being formed extending from said first space via said end space to said second space.
