Wherein the second end of the displacement plate 2 is fixed at one side of the first end of the rod body 1; the convex block 3 is fixed in the middle of the first end of the displacement plate 2 and is used for being inserted into a concave hole of the interbody fusion cage; the supporting plate 4 is installed at the first end of the rod body 1 and is perpendicular to the displacement plate 2, and a bearing area is formed between the supporting plate 4 and the displacement plate 2 and used for bearing the interbody fusion cage.
The convex blocks 3 are inserted into concave holes of the interbody fusion cage to limit the interbody fusion cage, so that the interbody fusion cage can be stably placed after the bearing area bears the interbody fusion cage.
Further, a handle is fixed at the second end of the rod body 1, and anti-skid patterns are formed on the handle.
Further, the length of the displacement plate 2 is greater than the length of the support plate 4.
After the tool is used for feeding the intervertebral fusion device into the intervertebral disc between two adjacent spinal active segments, the rod body 1 is pulled back, so that the convex block 3 is separated from the concave hole of the intervertebral fusion device, and then the intervertebral fusion device is subjected to displacement adjustment on one side of the intervertebral fusion device through the displacement plate 2.
Further, a support plate 4 is fixed to the first end of the rod body 1.
When the supporting plate 4 is fixed on the left side of the displacement plate 2, the displacement plate 2 is positioned on the right side of the intervertebral fusion device after the intervertebral fusion device is positioned in the bearing area, and the displacement plate 2 carries out left displacement adjustment on the intervertebral fusion device from the right side of the intervertebral fusion device; when the supporting plate 4 is fixed on the right side of the displacement plate 2, the displacement plate 2 is positioned on the left side of the intervertebral fusion device after the intervertebral fusion device is positioned in the bearing area, and the displacement plate 2 carries out rightward displacement adjustment on the intervertebral fusion device from the left side of the intervertebral fusion device.
