PROBLEM TO BE SOLVED: To provide an artificial bone prosthetic tool, when a bone defective part is filled with a powdery or granular prosthetic material, capable of filling an aimed site with the prosthetic material to the depth of a body of an operative field without dispersion or fall in a periphery, while controlling an amount of the prosthetic material.SOLUTION: A prosthetic tool has a funnel shape, and the material has deformable rigidity, so that the discharge of the prosthetic material stored inside the funnel is stopped by bending a tip of a straw part. When the straw part is clogged with the prosthetic material, the clogging is removed by pressing or kneading the straw part with fingers. This configuration can facilitate the prosthetic material filling work, reliably perform the prosthetic material filling work and shorten an operation time. 【課題】 粉体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】 本発明装置はロート状の形状をしており、その材質が変形可能な剛性を持ち、スロート部の先端を曲げることで、ロートの内部に収納された人工骨の排出を止めたり、人工骨材料がスロート部に詰まった時は、スロート部を指で押さえたり、もみほぐすことで、詰まりを解除できる。これによって手術での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２
