Because the second positioning needle comprises away from an end of bone traction frame and an end of close bone traction frame; If sleeve, rotating shaft are located to the end near bone traction frame, the 3rd positioning needle, than the more close human body of the second positioning needle, is not easy to manual adjustment rotating shaft (being subject to the impact of tissue); What is more, and the 3rd positioning needle likely can be between people's two lower limbs, and this position can be detected due to the inconvenience of blocking of tissue; Because the present invention selects the end away from bone traction frame, can avoid the impact of human body on concrete operations itself as far as possible.
Further, on described location-plate, the other end of the first strip cylindrical void length direction is fixed with the 4th positioning needle, described the 4th positioning needle and the first positioning needle, the second positioning needle one are in together with in location-plate becomes to determine a parallel plane of spacing, and the 4th positioning needle parallels with the first positioning needle.
Further, described the 3rd positioning needle is located in the 3rd positioning needle attaching means, and described the 3rd positioning needle attaching means is hinged on rotating shaft.
Now, in conjunction with the specific works principle of fracture of femoral neck screw of the present invention Wicresoft internal fixation operation vitro gunsight, its technique effect is described.The implantation site of supposing first hollow guide pin is to depart from the neck of femur axis apart from a on reverse S-line of Golden, the position of on the picture of side position, departing from neck of femur axis distance b; The implantation site of second hollow guide pin is to depart from the neck of femur axis apart from a on reverse S-line of Golden, the side position as on depart from neck of femur axis distance c position (to insert three internal fixation nails in routine operation, in order to select, convenient wherein the position of two should be on the same straight line of reverse S-line of Golden), the existing location that adopts following operation to realize this position and corresponding hollow guide pin should keep inserts angle.(described side position picture, reverse S-line of Golden are the medical imaging term)
The 1st step, first patient is placed in to reseting fracture on bone traction frame, then take the bone traction frame gin pole as fixed position, adjust the locus of location-plate by locus and angle adjusting mechanism, be convenient to the first positioning needle by outside top near the femur position of human body and require the first positioning needle to enter C type arm X-ray machine can irradiated zone, adjust (rotation or slide) rotation disc and make the second positioning needle roughly point to acetabular bone or femoral head position, requiring the second positioning needle also to enter C type arm X-ray machine can irradiated zone; Application C type arm X-ray machine is taken near reverse S-line of Golden image femoral head, adjust again the solid space position of first and second positioning needle by above-mentioned adjustment mode according to image, until two positioning needles are shown as straight line on reverse S-line of Golden, and this straight line and neck of femur axis distance are a; Determined that thus (and parallel distance is a), soon with location-plate, becomes to determine that a parallel plane of spacing is adjusted into the plane that is parallel to the neck of femur axis for first face of being parallel to the neck of femur axis.
The 2nd step, adjust the irradiation head of C type arm X-ray machine, make irradiation head be convenient to take near the side position of femoral head as image, the second positioning needle invariant position, by rotating shaft and corresponding hinged relationship make the 3rd positioning needle enter can irradiated zone (due to C type arm X-ray machine position, the medical personnel present position, the impact of the space factors such as bone traction frame position, need to utilize hinged relationship to adjust the angular relationship of the 3rd positioning needle and the second positioning needle, avoid affecting medical personnel's operation), the irradiation head of application C type arm X-ray machine is taken near the side position of femoral head as image, and according to the side position as Image Adjusting second, three positioning needle locus, wherein the adjustment of the 3rd positioning needle is mainly the rotation that relies on the axle that spins, until second, three positioning needles are shown as straight line on image, and straight line and neck of femur axis distance are b, determined thus second face (and parallel distance is b) that is parallel to the neck of femur axis, after regulating by determined of second and third positioning needle.
Due to, the second positioning needle is simultaneously in above-mentioned two planes that are parallel to the neck of femur axis, and these two planes that are parallel to the neck of femur axis are neither identical also not parallel, (by two antarafacials, determining a space line) is so its rectilinear direction of the second positioning needle is parallel with the neck of femur axis, the second positioning needle body surface position pointed is required to depart from the neck of femur axis apart from a on reverse S-line of Golden, the body surface position of departing from neck of femur axis distance b on the picture of side position, the space angle of the second positioning needle should be also the space angle (being all to be parallel to the neck of femur axis with hollow guide pin to be advisable in practical operation) that hollow guide pin should be taked.
The 3rd step, second positioning needle that will be connected as a single entity and rotating shaft take out from sleeve pipe and sleeve, to insert in sleeve pipe (from the above with first hollow guide pin of sleeve pipe coupling, the now sensing of hollow guide pin should be consistent with the sensing of sleeve pipe, the second positioning needle, point to predefined implantation site), then by hollow guide pin, to human body, insert internal fixation nail; Take out afterwards first hollow guide pin, along the first strip cylindrical void slip rotation disc (slip does not affect the parallel relation of the axial and neck of femur axis of sleeve pipe), the internal fixation nail of just having inserted walks opening from internal fixation nail; Repeat the 2nd step, until second and third positioning needle is shown as straight line in the side position on as image, and straight line and neck of femur axis distance are c; Determined thus the 3rd face (and parallel distance is c) that is parallel to the neck of femur axis, in like manner can determine the position that second hollow guide pin and internal fixation nail should be inserted by first and third face that is parallel to the neck of femur axis, and carry out subsequent operation.
Fracture of femoral neck screw of the present invention Wicresoft internal fixation operation vitro gunsight can also arrange the 4th positioning needle, it is but the second positioning needle replaced in the 1st step, determine first face of parallel neck of femur axis, and no matter how rotation disc rotates or slides, the second positioning needle all should be in this parallel neck of femur axis first face, the determining of face that this does not affect second parallel neck of femur axis, do not affect last technique effect yet.
When determining second face, second and third positioning needle should adopt the principle of " two intersection is determined a face ", rather than parallel definite mode, mainly contain two design reasons: adopt first parallel mode the 3rd positioning needle need be located to femur opposite side (lateral side of femur of crotch or another one leg).During photographic images, there is blocking of tissue, whether be inconvenient to compare two positioning needles in same straight line, and span is large, after adopting location-plate, also need to adopt again a structure that is similar to location-plate could realize this effect, the structure relative complex, cost increases; Second second and third positioning needle is located to femur the same side and parallel, according to above-mentioned known, the spacing between second and third positioning needle will be quite little, and whether same inconvenience compares two positioning needles in same straight line on view.
When determining second hollow guide pin implantation site, only need to determine the face of the 3rd parallel neck of femur axis.Owing to having determined first face before, second hollow guide pin and first hollow guide pin are in together in this face, so the 3rd step only needs along the first strip cylindrical void slip rotation disc, and observe and whether to reach preset distance and get final product by side position picture; Rotate rotation disc when avoiding maloperation to cause sliding, made second hollow guide pin space move towards misalignment, specially established the groove corresponding with the rotation disc anglec of rotation and character at the hoop sidewall subscript of capstan, the effect of a great deal of hornwork scale.Observe the relative position relation between groove and location-plate when determining first hollow guide pin implantation site, during the slip rotation disc and while determining second hollow guide pin implantation site, by the relative position relation of again observing between groove and location-plate, judge whether the anglec of rotation of rotation disc changes.
Practical application fracture of femoral neck screw of the present invention Wicresoft internal fixation operation vitro gunsight, only need two, three radiation imagings can determine a face, whole guide-localization process, only need imaging 5～7 times, thus can accomplish safe and effective, quickly and accurately the location.
