The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of torsion angle of neck of femur, lean forward angular measurement Device, the present invention also aims to provide the method using the measurement device femoral torsion angle, top rake.
The torsion angle of neck of femur of the present invention, the technical scheme of front inclination angle measurement mechanism, including workbench and dividing head, it is described Workbench is provided with scale wall and preceding laser head, side laser head, and vertical correction plate, weight, upper laser head.
The scale wall is provided with length indentation.
The preceding laser head, side laser head are respectively arranged on governor motion.
The governor motion is made up of movable stand, nut rotating disk, screw rod.
Using the measurement device femoral torsion angle, the method for top rake, carried out according to the following steps:
1. the femoral head of femur is placed in the chuck of dividing head fixed;
2. before adjusting laser head, the vertical beam of light of side laser head project before neck of femur respectively, side, adjust stock The position of bone is put makes neck of femur axis perpendicular to level;
3. the horizontal laser beam of preceding laser head is projected on the length indentation of scale wall through neck of femur, horizontal rotation indexing Head, makes the laser beam that the length indentation on scale wall is stopped by neck of femur up to maximum length, and now, neck of femur oval cross section is most Major diameter is parallel with scale wall;
4. the complex vertical correcting plate at femur medial and lateral condyle and greater trochanter rear minimum point, installs weight, upper laser Head;
5. incline, face upward femur, drive vertical correction plate, weight, the rotation of upper laser head so that the plumb line of weight hangs down with level Directly, the horizontal laser beam of upper laser head projects the upper surface formation laser beam projects line of workbench, laser beam projects line and mark The parallel lines that contour line is overlooked on the preceding surface of chi wall form angle α, and angle α is the torsion angle of neck of femur;
The top rake of the angle as neck of femur that 6. anglec of rotation indentation now on dividing head is rotated.
The torsion angle of neck of femur of the present invention, front inclination angle measurement mechanism and measurement femoral torsion angle, the method for top rake Beneficial effect be:Using the torsion angle of neck of femur, front inclination angle measurement mechanism measurement femoral torsion angle, top rake, can Simultaneously convenient, the directly perceived, torsion angle of accurately measure neck of femur and top rake.
