PROBLEM TO BE SOLVED: To surely suck and recover plural excised organismic tissues by providing plural suction ports on a tubular insertion part insertable to the forceps channel of an endoscope and turning only one of the opened suction ports to a suction operation state at the time of suction by a suction means. SOLUTION: After abutting a suction hole 7a at a very tip on the excised tissue, the opening part 6 of a communication pipe 10 is positioned on the hand side of the suction hole 7a, air is supplied to a balloon 12 and it is expanded inside a tip recovery part 5. In this state, the inside of a rigid part 4a is made a negative pressure through a suction cock and the communication pipe 10 by the suction means, the negative pressure is made to act on the suction hole 7a on a tip side from the balloon 12 and the excised tissue is sucked. Thereafter, in the state of expanding the balloon 12 and in the state of abutting the suction hole 7b on the excised tissue, the suction cock is moved to the hand side, the opening part 6 and the balloon 12 are positioned on the hand side of the suction hole 7b and the excised tissue is sucked by the suction hole 7b. |
