PROBLEM TO BE SOLVED: To provide an organism insertion implement and a suction method, allowing for reliable prevention of release of a biological tissue from a suction state when the biological tissue is sucked.SOLUTION: A vagina insertion member 5 is inserted into a vagina 1400. The vagina insertion member 5 includes : a top face 511a functioning as an abutment face to abut on a vagina wall defining the vagina 1400 at least one suction hole 59 for sucking the vagina wall to the side of the upper face 511a while the upper face 511a is abutting on the vagina wall and a blocking part 56 for blocking or suppressing the deviation of the vagina wall in the puncturing direction of a puncturing member 3 with respect to the upper face 511a when the vagina wall is punctured by the puncturing member 3 in the suction state in which the suction port 59 sucks the vagina wall.COPYRIGHT: (C)2015,JPO&INPIT【課題】生体組織に対する吸引を行なった際、当該生体組織が吸引状態から解放されるのを確実に防止することができる生体挿入具および吸引方法を提供すること。【解決手段】膣挿入部材5は、膣1400に挿入されるものである。この膣挿入部材5は、膣1400を画成する膣壁に当接する当接面となる上面511aと、上面511aが膣壁に当接した状態で膣壁を上面511a側に吸引する少なくとも1つの吸引孔59と、吸引孔59が膣壁を吸引した吸引状態で膣壁を穿刺部材3により穿刺した際に、膣壁が上面511aに対して穿刺部材3の穿刺方向にズレるのを阻止または抑制する阻止部56とを有する。【選択図】図50
