PROBLEM TO BE SOLVED: To provide a tap jig for the bone which has no risk of giving damage on the living soft tissue on the lower side with a tap part because it can control the tap depth and which is easily assembled before tapping operation and is easily disassembled and cleaned after tapping operation.SOLUTION: The tap jig for the bone includes a tap jig body 1 having the tap part 1c on the front end of a stem part 1b projecting from a handle part 1a and a tap depth controlling cylindrical body 2L. The tap depth controlling cylindrical bodies 2L and 2S are fitted around the stem part 1b of the tap jig body 1 while being fixed temporarily to prevent dropping off, and the rear ends of the tap depth controlling cylindrical bodies 2L and 2S are abutted on an abutting part 10a formed on the front end of the handle part 1a or on the outer surface of the stem part. With such a configuration, the tap part 1c of the tap jig body 1 projects by a predetermined dimension from front end openings of the tap depth controlling cylindrical bodies 2L and 2S.COPYRIGHT: (C)2012,JPO&INPIT【課題】タップ深さを制御できるためタップ部で下方の生体軟組織を傷つける危険性がなく、しかも、タップ作業前の組立作業やタップ作業後の分解、掃除作業を簡単に行うことができる骨用タップ治具を提供する。【解決手段】ハンドル部1aから突き出す軸部1bの前端にタップ部1cを設けたタップ治具本体1と、タップ深さ制御用筒体2Lとを具備し、タップ治具本体1の軸部1bにタップ深さ制御用筒体2L,2Sを脱落しないように仮止めした状態で脱着可能に外嵌挿着して、タップ深さ制御用筒体2L,2Sの後端をハンドル部1aの前端又は軸部外面に形成した当止部10aに前方から当止させると共に、タップ深さ制御用筒体2L,2Sの前端開口からタップ治具本体1のタップ部1cを所定寸法だけ突出させた構成の骨用タップ治具とする。【選択図】図1
