<P>PROBLEM TO BE SOLVED: To provide a high frequency treatment tool for an endoscope, by which cauterized viable tissue is not easily stuck to a high frequency electrode even if high frequency treatment is executed, and which can be repeatedly used continuously in a state where the high frequency electrode maintains the initial function. <P>SOLUTION: In the high frequency treatment tool for the endoscope, in which the high frequency electrode 4 brought into contact with a living body for cauterizing a contact surface on the living body side is arranged at the distal end of an electrically insulated sheath 1 inserted into and detached from the treatment tool insertion channel of the endoscope, a coating film A composed of a metal or alloy of gold or platinum is formed on a part or all of the surface of the high frequency electrode 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
