<P>PROBLEM TO BE SOLVED: To provide a treatment tool for an endoscope enabling even one operator to easily perform two operations of opening forcep cups and pushing the forcep cups forward which have to be performed at the same time in collecting biological tissue inside the parenchymatous organ. <P>SOLUTION: The treatment tool for the endoscope includes: a forcep sheath 11; a first forcep cup 13 and a second forcep cup 13 which are attached to a distal end of the forcep sheath and cooperate with each other to be openable/closable as a whole; and an operation wire 14 movably arranged in the forcep sheath along the axial direction and connected to each forcep cup to open/close each forcep cup when moved in its axial direction. The distal end of the first forcep cup is provided with a needle-like part 12 extending to the distal end side rather than the distal end of the second forcep cup, and at least a part of the needle-like part is arranged to overlap the second forcep cup when the closed state of each forcep cup is viewed in parallel with the axis of the operation wire. <P>COPYRIGHT: (C)2011,JPO&INPIT |
