PROBLEM TO BE SOLVED: To provide a zygote holder capable of easily holding and releasing a zygote, and an assembling method of such a zygote holder.SOLUTION: A zygote holder comprises a cylindrical member 10 and a slide member 30. The cylindrical member 10 has an inner space SP. The cylindrical member 10 includes an outer cylinder 11 and a tip cylinder 21 connected to a distal part of the outer cylinder 11. The slide member 30 is a member slidable relative to the cylindrical member 10. At least a part of the slide member 30 is disposed in the inner space SP of the cylindrical member 10. The slide member 30 includes a fixing member 36. The fixing member 36 fixes a linear member 40 having a loop-shaped part 43 projecting from a distal end 26 of the tip cylinder 21 and capable of receiving a zygote 3.SELECTED DRAWING: Figure 2ACOPYRIGHT: (C)2017,JPO&INPIT【課題】接合子を容易に保持可能および解放可能にする接合子保持具、および、そのような接合子保持具の組立方法を提供する。【解決手段】筒部材10とスライド部材30とを具備する接合子保持具。筒部材10は、内部空間SPを有する。筒部材10は、外筒11と、外筒11の遠位部に接続された先端筒21とを含む。スライド部材30は、筒部材10に対してスライド可能な部材である。スライド部材30の少なくとも一部は、筒部材10の内部空間SPに配置される。スライド部材30は、固定部材36を含む。固定部材36は、先端筒21の遠位端26から突出するとともに接合子3を受け入れ可能なループ形状部43を有する線状部材40を固定する。【選択図】図2A
