There is provided a device used for sampling a tissue within a lesion in a minimally invasive manner when a bronchus does not directly reach the lesion. A cell sampling needle 13 having a groove 16 engraved in a circumferential direction is formed at an end of a flexible wire 12. The wire and the needle are inserted into a flexible tube 11, and an end of the wire drawn out from a rear end of the tube is connected to a slider 29 inside an operation implement 20. The operation implement has a rack 22 and a pinion 27 engaging with the rack 22, and when the rack is pushed away via an operation bar 23, the pinion rotates, and in accordance with the motion, the slider first advances and then retreats. Accordingly, the cell sampling needle protrudes and withdraws in a moment from and into the end of the tube, thereby sampling of the lesion in the groove of the needle.
