PROBLEM TO BE SOLVED: To provide a tissue sampling tool capable of reliably sampling a tissue in a sufficient amount.SOLUTION: A tissue sampling tool 1 cutting away and sampling a tissue includes: a first member 21 formed in a cylinder shape and including an inner space S and a side hole 23 communicating with the inner space a second member 36 inserted into the inner space and configured so as to move relative to the first member a first protrusion 27 arranged in the first member and protruding toward an inner side of the side hole and a second protrusion 38 arranged in the second member and protruding to an opposite direction to the first protrusion. When the first member and second member are in such a position relationship that the first protrusion and second protrusion face and separate from each other, a tissue can enter into the inner space from the side hole.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】十分な量の組織をより確実に採取可能な組織採取具を提供する。【解決手段】組織を切離して採取する組織採取具1は、筒状に形成され、内部空間Sと、内部空間に連通する側孔23とを有する第一部材21と、内部空間に挿入され、第一部材に対して相対移動可能に構成された第二部材36と、第一部材に設けられ、側孔の内側に向かって突出する第一突出部27と、第二部材に設けられ、第一突出部と反対の方向に突出する第二突出部38とを備え、第一突出部と第二突出部とが対向して離間する位置関係に第一部材と第二部材とがあるときに、組織が側孔から内部空間に進入可能である。【選択図】図2
