Detailed Description
In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in figures 1 to 3, a femoral neck fracture nail-placing guider mainly comprises a triangular guider 1, an auxiliary positioner 2 and a holding handle part 3.
Specifically, triangle director 1 is the distribution of falling triangle, the central locating hole 11 that link up around the center department on the triangle director 1 is equipped with one, triangle locating hole 12 that link up around all being equipped with four on every side of triangle director 1, through setting up a plurality of triangle locating holes 12, be favorable to the adjustment and confirm three cannulation screw's position distribution, increase fixed stability.
The central positioning hole 11 and the triangular positioning hole 12 are obliquely distributed towards the lower part of the front side, and the included angle between the central positioning hole 11 and the triangular positioning hole 12 and the front side surface of the triangular guider 1 is 127 degrees, which is consistent with the femoral shaft angle, and is beneficial to the insertion of a kirschner wire in the operation.
The auxiliary positioner 2 is an auxiliary connecting rod 21, the length of the auxiliary connecting rod 21 is 5cm, and the auxiliary connecting rod 21 is arranged on the right side edge of the triangular guider 1 and is consistent with the sagittal position of the central positioning hole 11; the tail end of the auxiliary connecting rod 21 is provided with an auxiliary positioning hole 22, and a Kirschner wire is implanted into the auxiliary positioning hole 22, so that the body surface can be positioned in advance, and the injury in the operation is reduced. The inclination angles of the auxiliary positioning holes 22 are consistent with those of the central positioning hole 11 and the triangular positioning hole 12. Furthermore, the hole diameters of the central positioning hole 11, the triangular positioning hole 12 and the auxiliary positioning hole 22 are all 2.5mm, and are matched with the diameter size of the kirschner wire used in the operation.
The holding handle part 3 is vertically connected to the bottom of the triangular guide 1 and is used for holding by an operator.
