[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The combined bone fracture plate for orthopedic trauma is formed by clamping two arc-shaped splints arranged opposite to each other on both sides of the patient's affected limb, then inserting a locking screw on a locking block into the other locking block, and then tightening the nut to achieve the assembly between the two arc-shaped splints, and rotating the threaded rod on the arc-shaped splint to push the arc-shaped splint to fix the affected limb;

[0012] The combined bone fracture plate for orthopedic trauma compresses the elastic mechanism by pressing the rebound plate, and then inserts the plug plate into the assembly block on the adjacent arc-shaped splint. The rebound plate is released to use the rebound force of the elastic mechanism to cause the clamping block to be clamped into the clamping slot to realize the installation of the distance adjustment mechanism. The two movable plates are driven to move by rotating the screw rod. Since the threads at both ends of the screw rod are arranged in opposite directions, the two movable plates will move relative to or away from each other, thereby driving the traction rod to move. At this time, the traction rod will drive the positioning plate to move, thereby realizing the spacing adjustment between adjacent fastening components.

[0013] The combined bone fracture plate for orthopedic trauma is convenient for disassembly and assembly of bone fracture components, simple for on-site assembly, and can adjust and fix the spacing between adjacent bone fracture components, thereby reducing the difficulty of positioning the bone fracture components for staff.
