Further, the adjustable angle of the dynamic hip bone plate with the adjustable angle is not less than 20 degrees, namely α degrees can reach 125-145 degrees.
Further, the angle adjusting nut is screwed in or out for adjusting the angle α degrees of the goose head nail head, the anti-rotation piece, the locking nut and the tension nail.
Furthermore, the staple is connected with the steel plate and the femoral shaft, the tail part can select 3-15 holes with different specifications according to different fracture types, and the hole distances are all 16 mm.
Furthermore, a cancellous bone screw can be arranged in the anti-rotation piece and forms plane fixation with the tension screw.
Further, the anti-rotation tab is axially angularly adjustable.
Compared with the prior art, the utility model discloses a characteristics and progress as follows:
because the angle-adjustable bone fracture plate is of a split combined structure, compared with the integrated design of other products, the same product can correspond to the same series of products with different angle specifications, so that the application range is wider, and the angle adjustment is flexible and the joint is realized in use; meanwhile, the angle-adjustable anti-rotation piece connected with the goose head and the goose head can ensure the stability of installation and improve the installation precision in the installation process of the dynamic hip. The utility model discloses but angle regulation's power hip locking coaptation plate structure is simple relatively, and installation easy operation is reliable, and angle regulation scope is big, can be connected with the skeleton accurate reliable ground.
