PURPOSE: To improve cutting performance and durability by making the direction of extending a grinding grain cross the direction of extending an edge line in at least one of edge parts of two sampling blades. 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 part 1. In this case, the treating part 10 is provided with two sampling blades 13 and 14 to allow the opening or closing thereof by an operating wire of the linkage string 6 through an opening/closing mechanism 12. Moreover, 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 by grinding. The direction B of extending a grinding gain G is made to cross the direction A of extending an edge line 28 in at least one of the edge parts 27 of both the sampling blades 13 and 14. |
