Position is good, chooses the corresponding present invention, and the present invention is placed in patient femur's rotor by the retainer body
Skin surface, locator long axis distal end insertion Kirschner wire and the knee joint centre for being directed toward patient:
2, it is not required to incision patient skin and Kirschner wire is pierced by the positioning of the centre bore, later again directly on the outside of skin
After the kirschner pin position of the positioning of centre bore described in fluoroscopic examination is good, under the positioning of tripartite's location hole, three pieces grams are pierced
Family name's needle:
3, the pilot pin in the centre bore is taken out, perspective determines the position of tripartite's positioning hole Kirschner wire again, checks
The present invention is removed after errorless, and pierces the hollow nail along the position of three pieces of Kirschner wires of tripartite's positioning hole, again thoroughly
Inspection, which is looked into, determines that errorless rear operation terminates.
The beneficial effects of the present invention are: the present invention, which passes through, determines central point, while other three anchor points have been determined,
The characteristics of considering neck of femur Coronal and 15 ° of angles of femur long axis and 15 ° of angles of femur anticollis, designs the present invention, solves
Nailing of having determined positioning is inaccurate, position is inaccurate, direction is inaccurate, hollow nail unbalance stress and reduction take refracture after nail, avoids sky
The problems such as heart nail bit is gone out outside neck of femur solves the urgent need of clinician.
