The utility model discloses simple structure has increased the strengthening rib of chimb with the slope setting in the design, reasonable in design, and the intensity that can increase the coaptation edition of books body is prevented, ends the fracture of the coaptation edition of books body, and the screw hole divide into coarse thread and fine screw thread, simple to operate, stability is good, and the coaptation is effectual, and the clinical use security is high.
Description
Technical field
This utility model relates to orthopaedics medical instruments field, specifically a kind of locking metal bone fracture plate.
Background technology
Locking bone fracture plate is the most frequently used internal fixation apparatus of at present both at home and abroad treatment fracture, existing locking bone fracture plate one be pressurization hole with lock hole separately independently, separate; Another kind is that pressurization hole and lock hole link together, namely through hole is by pressurizeing hole and lock hole part is overlapping forms, namely the pressurize center of clearing end in hole does not overlap with the center of lock hole, although the pressurization hole of the blade plate of this kind of structure and lock hole link together, but its pressurization is independently with lock function, namely needs first to pressurize with ball screw, then locks by lock screw in other lock hole, finally ball screw is taken out, can lock by lock screw as required.The blade plate of the first structure has too much through hole, causes the intensity of blade plate poor; And although its pressurization hole of the blade plate of the second structure and lock hole link together, the size of this through hole longitudinal direction is comparatively large, reduces the intensity of blade plate to a certain extent.Therefore, for the blade plate of the second structure, further improvement is made to its structure, solve the problem of blade plate intensity difference.
Summary of the invention
Problem to be solved in the utility model is: overcome the deficiencies in the prior art, there is provided a kind of structure simple, reasonable in design, easy for installation, good stability, can increase the intensity of blade plate body, prevents blade plate body from rupturing, synthetism is effective, the angle type metal bone fracture plate that Clinical practice safety is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of locking metal bone fracture plate, comprise blade plate body, the both sides of described blade plate body are provided with the chimb be crisscross arranged, described blade plate body is provided with through hole, described through hole is between blade plate body and chimb, described through hole is superposed by pressurize hole and threaded bore portions and forms, the upper and lower of described screwed hole is respectively coarse thread and fine thread, is provided with the reinforcement be obliquely installed between described adjacent two through holes.
Further, described chimb is semicircle or rounded square structure.
Further, described pressurization hole is circular or kidney-shaped structure.
Further, the angle of the length direction of described reinforcement and blade plate body is 45 °-60 °.
Further, the material of described blade plate body is Ti-6Al-4V, Ti-6Al-7Nb, TA2, TA3 or 00Cr18Ni14Mo3.
Further, the cross section of described blade plate body and chimb is arc-shaped structure.
The advantage that this utility model has and good effect are:
This utility model structure is simple, and the reinforcement adding chimb in design He be obliquely installed is reasonable in design, and the intensity that can increase blade plate body is prevented, only blade plate body fracture; And screwed hole is divided into coarse thread and fine thread, easy for installation, good stability, and synthetism is effective, Clinical practice safety is high.
