<P>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. <P>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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
