Abstract
The invention discloses an adjustable special-shaped proximal femur locking plate. The adjustable special-shaped proximal femur locking plate comprises a main steel plate and a small steel plate. The main steel plate is a long-strip-shaped femur fixing steel plate. Screw holes for fixing bone nails are formed in the main steel plate, screw holes are formed in the small steel plate, and the small steel plate is detachably connected with the main steel plate through bolts. Through the structure, the adjustable special-shaped proximal femur locking plate is flexible to operate, a fixing position can be selected according to requirements to rebuild the small steel plate, and reliability of the position for fixing smashed cortexes on the intertrochanteric inner side or the intertrochanteric rear side is guaranteed.
Description
Technical field
The present invention relates to a kind of locking steel plate, particularly a kind of adjustability abnormity near end of thighbone locking steel plate.
Background technology
Along with the prolongation of human longevity and the arrival of aged society, postmenopausal osteoporosis and senile osteoporosis sickness rate increase, and can cause the increase of fractured near end of thighbone incidence rate.At present the major technique for the treatment of fractured near end of thighbone have that many pins are fixed, marrow internal fixation system, side roof system, dynamic condylar screw and proximal femur dissection locking steel plate, but these devices all have different defects, not strong for the fixedly specific aim of near end of thighbone.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of adjustability abnormity near end of thighbone locking steel plate, and it is resected femur fractured near end firmly, and uses flexibly.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of adjustability abnormity near end of thighbone locking steel plate, it is characterized in that: described adjustability abnormity near end of thighbone locking steel plate comprises main steel plate and little steel plate, described main steel plate is strip femur fixation steel plate, on main steel plate, have the screw for fixing bone pin, on described little steel plate, have screw and be connected by bolt and steel plate are detachable.
Further, described main steel plate near-end width is greater than main steel plate body width, and main steel plate near-end has a plurality of screws that vary in size.
Further, the side of described main steel plate near-end is arc.
Further, in described main steel plate main body, screw is crisscross arranged along main body bearing of trend is non-linear.
Further, the screw in described main steel plate main body is waist-shaped hole.
Further, described little steel plate is that side is the steel plate of L-type, and on little steel plate, has the screw varying in size.
The present invention compared with prior art, has the following advantages and effect:
1, the little steel plate of adjustability can be rebuild lockplate, and can select as required the fixed position of little steel plate, use more flexibly, and on little steel plate, have different screws to select screw according to practical situation, thereby it is fixing more reliable to make between tuberosity inner side or rear side pulverize cortex;
2, main steel plate near-end is wider, can towards different directions, be intersected and implant more lock screw by the screw distributing above, has improved hold, avoids coxa vara and screw to extract;
3, main steel plate main body screw is non-linear arranges, and prevents stress concentration, has increased screw hold, has strengthened the fatigue resistance of steel plate.
Accompanying drawing explanation
Fig. 1 is adjustability abnormity near end of thighbone locking steel plate schematic diagram of the present invention.
Fig. 2 is the side view of the main steel plate of adjustability abnormity near end of thighbone locking steel plate of the present invention.
Fig. 3 is the front view of the little steel plate of adjustability abnormity near end of thighbone locking steel plate of the present invention.
Fig. 4 is the side view of the little steel plate of adjustability abnormity near end of thighbone locking steel plate of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
As shown in Figure 1, adjustability abnormity near end of thighbone locking steel plate of the present invention comprises main steel plate 1 and little steel plate 2, main steel plate is strip femur fixation steel plate, main steel plate 1 near-end width is greater than main steel plate 1 body width, and main steel plate 1 near-end has a plurality of screws that vary in size, wherein main steel plate 1 near-end has 3 4.5mm screws along edge, at 3 4.5mm screw downsides, has 4 3.5mm screws, the distribution that assumes diamond in shape of 4 3.5mm screws.As shown in Figure 2, the proximal side of main steel plate designs for arc, not only can more press close to like this condyle bone shape of femur, and the near-end of arc design is in fixed bone screw, screw can form fixing by proximal curved ends from different directions, improve hold, avoided coxa vara and screw to extract.In main steel plate 1 main body, screw is crisscross arranged along main body bearing of trend is non-linear, prevents like this stress concentration, has increased screw hold, has strengthened the fatigue resistance of steel plate, and screw employing waist-shaped hole, and the operability of hold-down screw is more flexible like this.The total length of main steel plate 1 lengthens, and can make like this screw of far-end can be fixed on the better key portion of sclerotin, more stable and be more suitable for Minimally Invasive Surgery.
As shown in Figure 3 or Figure 4, the bending steel plate that little steel plate 2 is L-type for side, a side of the bending of little steel plate 2 has the screw mating with screw in main steel plate 1 main body, and when in use, 2 of little steel plates are bolted on main steel plate 1; The opposite side of the bending of little steel plate 2 has a 4.5mm screw and two 3.5mm screws, can select as required screw to carry out knochenbruch and fix, and can make between tuberosity inner side or rear side pulverize cortex fixing more reliable; On plate body outside the screw of little steel plate 2, have recess simultaneously, alleviated like this steel plate weight and still guaranteed armor plate strength.
Pass through technique scheme, adjustability abnormity near end of thighbone locking steel plate of the present invention when in use, first main steel plate 1 is pressed close to knochenbruch position, the near-end radian of main steel plate 1 and the condyle of femur position of bone are put and are matched, then select the position of little steel plate 2 and little steel plate 2 is fixed on main steel plate 1, then selecting the screw and the fixed position that need to be fixed according to practical situation.By such mode, adjustability abnormity near end of thighbone locking steel plate advantage of the present invention is as follows:
1, the little steel plate of adjustability can be rebuild lockplate, and can select as required the fixed position of little steel plate, use more flexibly, and on little steel plate, have different screws to select screw according to practical situation, thereby it is fixing more reliable to make between tuberosity inner side or rear side pulverize cortex;
2, main steel plate near-end is wider, can towards different directions, be intersected and implant more lock screw by the screw distributing above, has improved hold, avoids coxa vara and screw to extract;
3, main steel plate main body screw is non-linear arranges, and prevents stress concentration, has increased screw hold, has strengthened the fatigue resistance of steel plate.
Above content described in this description is only made for the present invention illustrating.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment; only otherwise depart from the content of description of the present invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
