The present invention is as follows using process：
1st, by fairlead of the invention 9 tentatively near neck of femur outer end, fixed plate 1 is basically identical with femoral shaft axis, uses
Be fixed on fixed plate 1 in femoral shaft through femoral shaft locking hole 12 by screw.
2. with laser rays Verticality gauge correction aiming pin 8 and the axis of fairlead 9 in same vertical plane.Correction navigator
Or C-arm X-ray machine is vertical.Pin 8 is aimed under the guiding of navigator or C-arm X-ray machine, display aims at pin 8 and femoral head
The position of the image of neck, adjustment aims at the position of pin 8, is overlapped with femoral head neck axis until aiming at pin 8, now pilot pin（Gram
Family name's pin）Axis also overlapped with neck of femur axis.
3. the height of fairlead 9 is adjusted so that laser rays is directed at entry point.Adjustment top rake is at 12 °~15 °.Adjust
A certain concrete condition afterwards is as shown in Figure 5, Figure 6.Implement pilot pin finally by fairlead 9（Kirschner wire）Inserting needle.
The present invention navigator it is image-guided under, it is first parallel with femur neck angle and top rake using the external pin 8 that aims at,
The external pin 8 that aims at is translated again to be overlapped with neck of femur rod axis.Or C arm X-ray machines it is image-guided under, first aim at pin using external
8 is parallel with femur neck angle, adjusts the top rake of guider at 12 °~15 °.External aiming pin 8 and femur neck are translated again
Axis overlaps.Finally by the guiding positioning guide pin inserting needle of fairlead 9.The present invention can improve accuracy, the safety of positioning guide pin
Property and validity, while in ensureing fixed configuration biomethanics efficiency, reduce iatrogenic and ionising radiation infringement.
Although the present invention illustrates above-mentioned preferred embodiment, although it should be noted that those skilled in the art can
To carry out various change and remodeling, unless such change and remodeling deviate from the scope of the present invention, otherwise should be construed as being included in
