PROBLEM TO BE SOLVED: To continuously and easily collect viable tissue and also to improve an operability in a tissue collecting part by forming a pair of forceps by means of a pair of mobile jaws which are rotated with respect to a tip cover and engaging a pair of independent actuator means being freely rotatable with the mobile jaws. SOLUTION: An endoscope treatment tool 1 is provided with an inserting part 2 to be inserted to a forceps channel of an endoscope and inserted to a celom and a treatment tool operating part 3 is integrally fixed to its near end. The inserting part 2 is provided with the tissue collecting part 5 which is integrally fixed to the far end of a sheath 4 and the tissue collecting part 5 is constituted of a pair of forceps 12a and 12b supported by the tip cover 11 so as to be freely rotatable and of a sucking nozzle 13 or the like. The forceps 12a and 12b is arranged to grasp a part of viable tissue in one end part and to excise it as a tissue piece, is formed as the pair of mobile jaw 20a and 20b for holding the tissue piece and is operation possible independent of operation wires 9a and 9b. |
