When the utility model is used, the first positioning kirschner wire is generally driven into the neck of the femur through perspective after the fracture is reset (the layout of the three wires is generally an inverted triangle, the lowermost wire is driven first, the ideal position positive piece is close to the lower edge of the neck of the femur, and the side piece is in the center of the neck of the femur); because the positioning pin driven in through perspective is generally satisfactory, even if the adjustment is fine adjustment, the fine adjuster is used for further adjusting the first Kirschner wire to the ideal position; the honeycomb guider is installed through the first needle (all honeycomb through holes 4 in the device are parallel), and the second and third parallel needles are punched in sequence.
In the use of the femoral neck Kirschner wire positioning and adjusting system, the rational positions of the three hollow screws are parallel to each other and are dispersed, and the rational positions are as close to the edge of the femoral neck as possible. Clinically, roughly marking the general position of the lowermost positioning kirschner wire after the external kirschner wire is placed for perspective, then driving the kirschner wire into a femoral neck by hands according to the mark, wherein the position of the kirschner wire is difficult to be in a rational position at this time, the kirschner wire possibly deviates upwards (a normal position image) and deviates forwards and backwards (a lateral position image) in the femoral neck, then placing the kirschner wire to be adjusted into a channel of a first layer of first holes through a designed fine adjuster, if the upper and lower positions of a needle entering point are good (a normal position), selecting a second hole (3 degrees) of a second channel according to the degree deviating from the center, a second hole (6 degrees) of a third layer of channel and a second hole (9 degrees) of a fourth layer of channel only by regulating the deviation of the front and the back of the lateral position;
if the upper and lower positions of the needle entering point are upward or downward (positive position), the side position is not at the center, the upward and downward adjustment is continued, and the forward and backward positions of the side position are adjusted, the Kirschner wire to be adjusted is placed in the channel of the first layer of first hole, and then the third hole (3 degrees) of the second layer of channel, the third hole (6 degrees) of the third layer of channel and the third hole (9 degrees) of the fourth layer of channel are selected according to the degree deviated from the center; this produces the desired first lowermost positioning k-wire.
The invention will be further described with reference to specific embodiments and applications.
Examples
Firstly, when a kirschner wire is driven and the lateral perspective is not in the center, the central line of the femoral neck is drawn on the lateral image, the included angle between the femoral neck and the kirschner wire to be adjusted is calculated, the angle closest to the 3 degrees, the 6 degrees and the 9 degrees is selected according to the calculated angle, and the corresponding channel is inserted.
Then, install the central point that the locating kirschner wire of below is put at second honeycomb sleeve 7, press close to the thighbone near-end with the honeycomb director as far as possible, increase the strength of control guide pin direction, beat two piece other parallel kirschner wires from the centre bore of first honeycomb sleeve 4, third honeycomb sleeve 8, if the perspective is not enough to press close to the cortex of bone, then continue to adjust through the subassembly of honeycomb sleeve. Thus, the ideal three-parallel and dispersed hollow screws which are as close to the edge of the femoral neck as possible can be driven, and favorable conditions are provided for fracture pressurization and fixation.
The first positioning kirschner wire can be quickly adjusted to an ideal position through the fine adjuster, and the adjustment can be quantized; after the position of the first Kirschner wire is satisfied, the honeycomb sleeve is arranged, so that the three Kirschner wires can be completely parallel and are close to the cortical bone of the femoral neck.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
