PROBLEM TO BE SOLVED: To provide a filling jig for artificial bone material capable of performing filling work with controlled amount of filling for a target site even to a deep part of a surgical field of the body without scattering or falling of material to the area around when filling a bone defective part with a powdery or granular artificial bone material.SOLUTION: The device according to the present invention is composed of an inner member and an outer member both made of finger press-deformable material. The outer member has a shutting member disposed which acts as a shutter between the inside and the outside, the shutting member being closed in a normal state. When artificial bone material is filled, the inner member is slid for pushing the shutting member away to make the inner member itself protrude to the outside, thereby enabling the artificial bone material to be discharged outside. In addition, pressing down on the outer member with fingers gives an effect like disentangling the throat section with fingers, releasing the blockage of internal walls of the throat section. This facilitates the filling of the artificial bone material, ensuring reliable filling work and shortened surgery time.COPYRIGHT: (C)2015,JPO&INPIT【課題】 粉末や顆粒状の人工骨材料を骨欠損部に補填する時に、狙った部位に、周囲への散らばりや脱落なしに、術野の体内の深い部分まで、補填量を制御しながら補填ができる人工骨補填治具である。【解決手段】 本発明装置は指で押すことで変形可能な材質で作られたインナー部材とアウター部材で構成され、アウター部材には内部と外部を閉鎖する機能を持った部材が設置され、通常は閉鎖されている。人工骨を補填する時に、インナー部材をスライドさせる事により閉鎖機構を押しのけてインナー部材が外部に突出して、人工骨を外部に排出することができる。また、補填材のアウター部材の上から指で押すことにより、スロート部を指でもみほぐすような効果が得られ、スロート部内壁面の詰まりを解除できる。これによって人工骨補填作業を容易に行い、補填作業の確実化と手術時間の短縮が可能な構造となっている。【選択図】図3
