ARTIFICIAL BONE FILLING CONTAINER

To more simply implement an artificial bone filling container capable of inhibiting an artificial bone stored inside the container from being unintentionally discharged.SOLUTION: An artificial bone filling container 1 comprises: a cylinder part 2 having a storage part 10 and a diameter reduction part 12; and a slit 3. A diameter of a first circumscribed circle circumscribed on an inner peripheral surface of the storage part 10 on a cut section obtained by cutting the storage part 10 in a direction orthogonal to a first axis line O is equal to or longer than a diameter of a second circumscribed circle circumscribed on an outer peripheral surface of an artificial bone 30 on a cut section obtained by cutting the artificial bone 30 in a direction orthogonal to a second axis line Z1. A diameter of a third circumscribed circle circumscribed on an inner peripheral surface of the diameter reduction part 12 on its cut section in the direction orthogonal to the first axis line O becomes smaller as it goes toward one end side. A minimum diameter D3 of the third circumscribed circle is smaller than a diameter D2 of the second circumscribed circle. The slit 3 extends beyond one end side of the diameter reduction part 12 to the other end side. The length of the slit 3 is in a range of 1.02 to 1.62 times as long as the diameter of the first circumscribed circle.SELECTED DRAWING: Figure 2 【課題】内部に貯留された人工骨が意図せずに排出されてしまうことを抑制し得る人工骨補填容器を、より簡易に実現する。【解決手段】人工骨補填容器１は、貯留部１０及び縮径部１２を有する筒部２とスリット３とを備える。貯留部１０を第１軸線Ｏと直交する方向に切断した切断面における貯留部１０の内周面に外接する第１外接円の直径は、人工骨３０を第２軸線Ｚ１と直交する方向に切断した切断面における人工骨３０の外周面に外接する第２外接円の直径以上である。縮径部１２は、第１軸線Ｏと直交する方向の切断面における自身の内周面に外接する第３外接円の直径が一端側に向かうにつれて小さくなり、第３外接円のうちの最小の直径Ｄ３が第２外接円の直径Ｄ２よりも小さい。スリット３は、縮径部１２の一端側の端部を越えて他端側まで延び、スリット３の長さは第１外接円の直径の１．０２倍〜１．６２倍の範囲内である。【選択図】図２
