The bone plate is usually made of metal materials, such as stainless steel, titanium alloy, etc., and has good biocompatibility and corrosion resistance. The shape and size of the bone plate vary according to the site and type of fracture. The use of the bone plate needs to be selected and customized according to the patient's specific situation and surgical plan.

[0003] When in use, the surgeon can select plate bodies of different specifications according to the actual fracture situation, and choose to use locking blocks or pressure blocks at each threaded connection hole to connect locking screws or pressure screws to meet clinical needs.

[0027] Specifically, the second bone plate 3 forms a movable structure through the screw rod 5 and the movable block 6, and the threads on both sides of the screw rod 5 have opposite rotation directions, and the number of the movable blocks 6 is two.

[0028] Through the above technical solution, it is convenient to turn the knob at the outer end of the screw rod 5 by hand to drive the screw rod 5 to rotate, because the threads on both sides of the screw rod 5 have opposite rotation directions, and the two moving blocks 6 are symmetrically arranged on both sides of the screw rod 5, and then the rotation of the screw rod 5 drives the moving blocks 6 to move in opposite directions, thereby achieving the effect of the two moving blocks 6 moving in opposite directions.
