PROBLEM TO BE SOLVED: To provide a rejectscope to obtain curing efficacy keeping safety in higher efficiency. SOLUTION: A rejectscope comprises a scope 1 and a sheath 3 for inserting the scope 1 into a human body, a working element 2 installed at the hand side of the sheath 3, an electrode unit 4 connected to the working element 2 and an electric conducting member for supplying electric current to the electrode unit 4. By operating the working element 2, the electrode of the electrode unit 4 from the opening at the top end of the sheath 3 is made to project to use. The electrode comprises a freely rotatable roller body made of an electrically insulating material and at least two of electric conductive needles are formed on the outer periphery of the roller to construct a bipolar electrode. |
