Abstract
The present invention discloses a two-stage locating device and the method thereof. In stage-one, the preliminary locating device finds the approximate area of the locking hole encircled with the magnetic material on the intramedullary nail. In stage-two, the pinpoint device has a plurality of targeting devices and includes a transparent plate with a plurality of alignment lines. According to the deviations between each pointing device and the alignment lines, the direction of the pinpoint device for further adjustment can be determined. The present invention can determine the position and the orientation of the locking hole on the intramedullary nail quickly and precisely to shorten the time spent to implant the intramedullary nail. Furthermore, the present invention can also have a conductive circuit to connect to an alarm device. Thus, the precise location can be determined through the different alarm signals based on the contact conditions between each directing devices and the conductive circuit.
