PROBLEM TO BE SOLVED: To provide a fracture part fixing tool that is capable of surely restricting rotation of a bone chip at a fracture part and is capable of surely and easily being implanted into the bone chip.SOLUTION: A fracture part fixing tool 1 comprises: a cylindrical sleeve 2 and a hook pin retention part 3 that is housed in the sleeve 2 so as to be movable in an axial direction. The sleeve comprises a tip closing part 22 and side holes 24a, 24b, and the hook pin retention part comprises hook pins 5, 6 that protrude from the side holes by being pushed from behind. The hook pin 5 includes a main body part extending in the axial direction in a state of being tilted to the lower part of one side part, and the hook pin 6 includes a main body part extending in the axial direction in a state of being tilted to the lower part of the other side part. The main body parts 51, 61 comprises in-bone penetration thin tips 52, 62 that gradually become thinner and are curved in directions of the outer side surfaces of the hook pins 5, 6, respectively.SELECTED DRAWING: Figure 29COPYRIGHT: (C)2017,JPO&INPIT【課題】骨折部における骨片の回転を確実に規制可能であり、かつ、骨片への刺入が確実かつ容易に行うことができる骨折部固定具を提供する。【解決手段】骨折部固定具1は、筒状スリーブ2と、スリーブ2内に軸方向に移動可能に収納されたフックピン保有部3からなる。スリーブは、先端閉塞部22と、側孔24a,24bを備え、フックピン保有部は、後方からの押込により、側孔より突出するフックピン5,6を備える。一方のフックピン5の本体部は、一方の側部下方に傾斜した状態にて軸方向に延び、他方のフックピン6の本体部は他方の側部下方に傾斜した状態で軸方向に延びている。本体部51,61は、徐々に肉薄となりかつフックピン5,6の外側面方向に湾曲した骨内進入用薄肉先端部52,62を備える。【選択図】図29
