Positioning device for fixing femoral neck and use method of positioning device

The invention relates to the field of medical equipment, in particular to a positioning device for fixing femoral neck and a use method of the positioning device. The positioning device for fixing thefemoral neck comprises a body, wherein a plurality of linear through holes are formed in the body and form an equal-interval array, a coordinate system is marked on the surface of the head end of thebody and forms a corresponding relation with the through holes of the array, the tail end of the body is an oblique plane, and an included angle of 135 degrees is formed by the oblique plane and theside surface, with the smallest area, of the body. With the adoption of the positioning device, a rookie doctor without experience can position a fastening nail precisely and effectively, interferenceof the human ability factor is eliminated to the greatest extent while the maximum biomechanical efficiency is realized, dependence of positioning work on experience is avoided, and accidental factors such as lateral sway, slip
