PROBLEM TO BE SOLVED: To provide a bone-fixing tool applicable to a wide range of use such as application to an embedding portion in minimal invasive surgery.SOLUTION: The bone-fixing tool includes: an axis 7 having a first end part 8 and a second end part 9 a conduction hole 11 extending to the second end part 9 from the first end part 8 so as to be coaxial to the axis 7 and plug members 30, 40 and 41 which can be inserted into the conduction hole from the first end part 8 and also can be guided along the conduction hole for blocking the conduction hole at the second end part 9. The plug member has a spherical configuration. The bone-fixing tool having such a structure can guide the guide wire through the inner part thereof and can block the open end of the bone-fixing tool by inserting the plug members after the bone-fixing tool is fixed to the bone.COPYRIGHT: (C)2015,JPO&INPIT【課題】たとえば最小侵襲手術における埋め込み部位への適用など、幅広い範囲の用途に適用可能な、骨固定具を提供する。【解決手段】第1端部8および第2端部9を有する軸7と、軸7と同軸に第1端部8から第2端部9に延びる導通穴11と、第1端部8から導通穴に挿入可能で、かつ、導通穴をその第2の端部9において閉鎖するために導通穴に沿って案内可能な栓部材30,40,41とを備え、栓部材は球形状を備える。このような構造を有する骨固定具によれば、その内部を通してガイドワイヤを案内可能であり、また、骨固定具が骨に固定された後に、栓部材を挿入して骨固定具の開放端を閉鎖することができる。【選択図】図9
