PURPOSE: To achieve a cleaning of edge parts easily and accurately to be made sanitary by providing two sampling blades with the edge parts adapted to approach or separate from each other with the opening or closing thereof to sample a tissue in vivo with higher cutting performance of the edge parts by an electrolytic grinding applied at least to the edge parts. CONSTITUTION: In a treating device for an endoscope, a treating part 10 provided at the tip part of a linkage string 6 to be inserted in vivo through an endoscope is operated remotely by an operating section 1. In this case, the treating section 10 is provided with two sampling blades 13 and 14 to allow the opening or closing thereof with an operating wire of the linkage string 6 through an opening/closing mechanism 12. Both the sampling blades 13 and 14 are provided with edge parts 27 adapted to approach or separate from each other with the opening or closing thereof. Moreover, an electrolytic grinding is applied at least to the edge parts 27 of both the sampling blades 13 and 14. In other words, both the sampling blades 13 and 14 are provided with a sampling chamber 26 inside both cups 24 and 25 and the edge parts 27 are formed on a circular periphery of a releasing part 26a thereof. |
