PROBLEM TO BE SOLVED: To provide a fixation device stably fixing a graft ligament in a hole through a bone.SOLUTION: A fixation device 10 for fixing the graft ligament to be fixed in the hole through the bone at an opening part of the hole through the bone has a pair of or more wedge-shaped through-holes 11, the diameter of which is gradually reduced as heading from one end to the other end. A vertex or a side of a small diameter side 11b in one wedge-shaped through-hole 11 and a vertex or a side of a small diameter side 11b in the other wedge-shaped through-hole 11 to be paired are configured to face each other on both sides of the fixation device central part.COPYRIGHT: (C)2014,JPO&INPIT【課題】移植用靱帯を骨貫通孔内に安定に固定できる固定具を提供する。【解決手段】骨貫通孔内に固定される移植用靱帯を、前記骨貫通孔の開口部で固定するための固定具10であって、一端から他端に向かうにしたがって径が小さくなる楔形貫通孔11を、一対以上有し、一つの楔形貫通孔11における小径側11bの頂点または側辺が、対となる他の楔形貫通孔11における小径側11bの頂点または側辺と、固定具中心部を挟んで互いに対向していることを特徴とする固定具10。【選択図】図1
