Detailed ways

Below in conjunction with accompanying drawing, the present invention is further described:

As shown in the accompanying drawings, a vertebral body front protection device for total vertebral body resection of the spine is characterized in that it is provided with a guard plate 1, and the left end of the guard plate 1 is gradually thickened to form a left stopper 2. The middle part of the left end surface of the left retaining part 2 is provided with a threaded hole, and the threaded hole is provided with at least one, and the left handle 3 is connected in the threaded hole, and the end face of the left retaining part 2 on the side of the threaded hole is provided with Guide the inserted insert plate 4, the insert plate 4 has the same width as the guard plate 1, the right end of the guard plate 1 is provided with a connecting convex plate 5, and the upper side of the connecting convex plate 5 is provided with an inner connecting screw hole, The connecting convex plate 5 is connected with the right handle 6, and the left end of the right handle 6 is provided with a connecting concave head 7, and the connecting concave head 7 is provided with an external connecting screw hole at the same position as the internal connecting screw hole. The outer connection screw hole and the inner connection hole are provided with connecting bolts 9, and the connecting bolts 9 pass through the outer connecting screw holes and the inner connecting screw holes to realize the connection between the connecting convex plate 5 and the connecting concave head 7.

Further, there are at least two external connection screw holes, and the connection height between the right handle 6 and the guard plate 1 is adjusted by adjusting the connection between different external connection screw holes and internal connection screw holes, and then different heights are used for Adapt to patients with different fat and thin.

Further, the thickness of the guard plate 1 is 2 mm, the width of the guard plate 1 is 20 mm, the thickness of the left end of the left blocking part 2 is 5 mm, and the thickness of the connecting convex plate 5 is 5 mm.

Further, the thickness of the insertion plate 4 is 2mm and the width is 20mm, which is convenient for insertion.
