<P>PROBLEM TO BE SOLVED: To provide a high frequency treating implement for an endoscope capable of smoothly washing cauterization pieces of mucous membrane tissue or the like caused around a high frequency electrode during cutting treatment and quickly performing a cutting operation without affecting the protrusion and retraction state of the high frequency electrode into a water feed amount jetted from a water feed path and the state of a water stream. <P>SOLUTION: Inside a sheath 1, a wire insertion hole 2 where an operation wire 5 connected to the high frequency electrode 4 is inserted so as to be freely moved back and forth in an axial direction and the water feed path 3 are formed in parallel independent of each other. Also, a water feed nozzle 8 for bending the jetting direction of the water which has passed through the water feed path 3 toward the high frequency electrode 4 is formed at the most distal end part of the sheath 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
