PROBLEM TO BE SOLVED: To easily sample an effective amount of tissue and to easily take out the sampled tissue by slidably mounting a cutter tubular body into a puncture tubular body, pricking the cutter tubular body into the body, sucking the vital tissue and cutting the same by the cutter tubular body. SOLUTION: The tissue sampling device 30 comprises a catheter 31 and a manipulation section 32. A syringe 33 is attachably and detachably connected to the base end of the manipulation section 32. The catheter 31 comprises triple cylindrical members and the outermost peripheral side is a sheath member 34. The puncture tubular body 35, which is disposed in this sheath member 34 and is displaceable to a retreat position and an operating position, opens the front end of a main body pipe 35a and a needle tip 35b is formed. A suction hole 35c is formed in the proximate position on the flank of the main body pipe 35a. The cutter tubular body 36 is mounted in this puncture tubular body 35 and the blade edge 36a at this front end is made slidable and displaceable to the front and rear of the suction hole 35c. |
