摘要： PROBLEM TO BE SOLVED: To provide a stereotactic apparatus for a locking nail, by which the position of a horizontal hole in the locking nail is correctly and highly reliably detected. SOLUTION: The stereotactic apparatus for the locking nail 40 includes two oscillation circuits arranged along a longitudinal direction. The apparatus comprises a guide cylinder for disposing a holing apparatus, etc., which is advanced to horizontal holes 42, 44. Three oscillation circuits 54 are arranged on a first plane 52 and to be respectively equal in distance from a first center 60. Three oscillation circuits 58 are arranged on a second plane 56, which is extended in parallel with the first plane 52, and to be respectively equal in distance from a second center 62. Both the planes 52, 56 are mutually oppositely arranged so as to allow the normal line of one surface to be extended through both the centers 62, 60. One pair of oscillation circuits 64, 66 are arranged at interval from a straight line 48 which is extended after passing through the both centers 62, 60. The straight line connecting the pair of oscillation circuits 64, 66 is substantially orthogonally crossed with the longitudinal direction of the locking nail 40 in a state where the stereotactic apparatus is aligned with the locking nail.
