Percutaneous pedicle internal fixation is a pedicle minimally invasive internal fixation technology which is widely applied clinically at present, and has the advantages of small wound, less bleeding, short operation time, quick recovery of patients and the like compared with the traditional open pedicle screw technology. Because the percutaneous pedicle screw technology is used for placing the screw under the guidance of the C-arm, each step has accurate imaging data, the accuracy of the screw placing is even higher than that of the traditional open free-hand screw placing, and the percutaneous pedicle screw technology is widely applied to operations such as vertebral fracture and lumbar vertebra degeneration.
In nail placement, due to the complex anatomy of the spine, erroneous needle insertion can lead to serious complications such as (1) spinal cord and dural sac injuries: when the needle is inserted in the operation, the inward angle is more than 15 degrees, which is easy to cause acute injury of spinal cord and dural sac; (2) nerve root damage: the pedicle screws are laterally and downwardly directed, and the screws approach or partially pass through intervertebral foramen, possibly damaging nerve roots; (3) injuring viscera or great vessels by using the guide needle: because the operator can only operate under the normal projection and can not carry out lateral observation, the guide pin is easy to break the cortex of the front edge of the vertebral body and hurt the internal organs and great vessels; (4) inner fixed object breaking: post-operative premature weight-bearing activities or internal fixture quality problems can lead to internal fixture breakage. Accordingly, the present invention is provided.
