PROBLEM TO BE SOLVED: To provide a photoelectric probe device that has no instability of electrical contact with a human body surface, requires no alignment of an optical axis with an electrical contact point and can simultaneously perform two kinds of electric and optical treatments.SOLUTION: A photoelectric probe device having a light generation part 10 and a current generation part 20 comprises a probe head 30 that uses an optical fiber 11 to guide light generated by the light generation part 10, uses a conductive wire 22 to guide current generated by the current generation part 20, and almost simultaneously directs and supplies the guided light and current to a same section on a human body surface. The probe head 30 comprises: a conductive electrode (a probe electrode) 31 that conducts electricity by coming into contact with the human body surface an electrode holder 36 that is electrically insulated from the conductive electrode and the optical fiber 11 that is provided in an inner cavity. A light emitting hole 33 is located within a surface area in contact with the human body surface in the conductive electrode and is arranged at a position where a light outputting end face of the optical fiber does not project outward from a surface of the conductive electrode.COPYRIGHT: (C)2014,JPO&INPIT【課題】人体表面との電気的接触の不安定さが無く、光軸と電気的接触点との位置合わせが不要で、電気と光の2つの施術を同時に行える光電プローブ装置を提供する。【解決手段】光電プローブ装置は、光発生部10と電流発生部20を有し、光発生部10で発生する光を光ファイバー11で導光させ、電流発生部20で発生する電流を電気導線22にて導電させ、導光させた光と導電させた電流とを人体表面の同じ箇所に、略同時に誘導・供給するプローブヘッド30を備える。プローブヘッド30は、人体表面へ接触して導電する導電性電極(プローブ電極)31と、導電性電極と電気的に絶縁された電極ホルダー36と内部の空洞に設けられる光ファイバー11で構成される。光射出孔33は導電性電極の人体表面に接する表面領域内に位置し、且つ光ファイバーの光出力端面が導電性電極の表面より外に突出しない位置に配置される。【選択図】図1
