Abstract

The utility model discloses a porous structure niti alloy vertebral plate which comprises a vertebral plate body, a limiting groove is formed in the vertebral plate body, a sliding block is connected in the vertebral plate body in a sliding mode, the two sides of the sliding block are connected with the interior of the limiting groove in a sliding mode, a secondary positioning hole is formed in the sliding block, and the secondary positioning hole is connected with the interior of the limiting groove in a sliding mode. End V-shaped recesses are formed in the two ends of the vertebral plate main body, side V-shaped recesses are formed in the two sides of the vertebral plate main body, and a through groove is formed in the vertebral plate main body. According to the niti alloy vertebral plate with the porous structure, the vertebral plate main body is preliminarily fixed through cooperation of second auxiliary positioning holes and screws, then reinforced fixing can be conducted again through cooperation of main positioning holes and screws, and sliding adjustment can be conducted along limiting grooves by sliding sliding blocks; after the sliding block moves to a proper position, key parts can be reinforced through the secondary positioning holes and the screws.
