In 223, the bone cement Jing bone cements hand-hole 23 in endoporus 223 is flowed out and is combined with bone, afterwards, positioned at two of spinal column side
Or multiple bone cement screws be one group, by this group of bone cement screw with pitman connect, will pitman be placed on this group of bone cement
In the U-shaped mounting groove 13 of screw, it is generally the case that two or more bone cement screws not point-blank, put pitman ratio
It is more difficult, in the present invention U-shaped nail seat can along 21 universal rotational of spherical construction section, now can with rotary U-type nail seat to correct position,
Put pitman after the completion of adjustment, then support pin 4 is mounted in the top of U-shaped nail seat 1, screw support pin 4, pitman is compressed, so far
Complete the implantation of bone cement screw.
In implantation process, it cannot be guaranteed that point-blank, it is relatively difficult to put pitman for bone cement screw in one group,
And U-shaped nail seat along 21 universal rotational of spherical construction section, can adjust the position of U-shaped nail seat in the present invention, multiple bone cements are made
The U-shaped mounting groove of screw is tried one's best point-blank, conveniently puts the operation of pitman.
Under normal circumstances, the fixed operation 1 year or so of scoliosis, it is possible to which the bone cement screw of implantation is taken out, by
In bone cement screw long period in human body, pitman, the U-shaped nail seat of bone cement screw, spherical installation portion and bone
It is sticked together with meat, especially bad taking-up, and can between U-shaped nail seat 1 and the spherical construction section 21 of screw body 2 in the present invention
To rotate, after pulling down support pin and mounting bar, rotating U-shaped nail seat can just be such that U-shaped nail seat separates with spherical installation portion, convenient to take out
Bone cement screw.
Embodiment described above is only that the preferred embodiment of the present invention is described, not the model to the present invention
Enclose and be defined, on the premise of without departing from design spirit of the present invention, technical side of the those of ordinary skill in the art to the present invention
