When being implanted into the first supporting block 10 and the second supporting block 20 vertical direction can precise positioning, by the first positioning column 122 of protrusion and
Second positioning column 123 is placed in the first supporting block 10, saves the space setting implantation cavity 30 being more than.
6, horizontally arranged third positioning column 124, the 4th positioning column 224, third locating slot 225 and the 4th locating slot
125, make the first supporting block 10 and the second supporting block 20 precise positioning in the horizontal direction.
7, it after split type artificial vertebral body implantation human body, is fixed, is made point by hammering into screw at left and right sides of U-shaped structure
Body formula artificial vertebral body is fixed on backbone.
8, implantation cavity 30 is for being put into broken bone, while the vertebra of split type artificial vertebral body upside and downside being made to pass through implantation
The over and under of cavity enters, convenient for merging for split type artificial vertebral body and vertebra.
9, second side 12, third side 13, the 5th side 22 and the side plate structure of the 6th side 23 are split type people
Work centrum provides support, and the micropore being arranged on split type artificial vertebral body has certain when split type artificial vertebral body is squeezed
Buffer function, be unlikely to make split type artificial vertebral body because excessive impact force is damaged, the vertebra above artificial vertebral body
Bone can enter split type artificial vertebral body by the micropore of obturator upper surface, and the vertebra below artificial vertebral body can pass through filling
The lower surface of body enters split type artificial vertebral body, increases merge contact area of the split type artificial vertebral body with vertebra, meanwhile, it fills out
The micropore for filling the upper surface and the lower surface of body has certain anti-skidding effect, make implantation split type artificial vertebral body and top and under
Will not occur the case where shifting and misplacing because of activity between the vertebra of side.
The above are only specific embodiments of the present invention, does not limit the protection scope of the utility model with this；Not
It violates made any replacement on the basis of the utility model is conceived and improves, the category protection scope of the utility model.
