Abstract

The invention discloses an artificial vertebral plate used after spine laminectomy. The artificial vertebral plate consists of a vertebral plate, a first screw and a second screw, wherein a first long round hole and a second round hole are formed in two ends of the vertebral plate, the first screw is arranged in the first long round hole, and the second screw is arranged in the second long round hole. The vertebral plate is firstly placed above the spine to be positioned, two threaded holes are drilled in sections where the vertebral plate is to be reconstructed through vertebral pedicle screws on two sides, the vertebral plate is mounted, the first screw and the second screw are tightened, mounting is finished, the vertebral plate is located above the spine, so that closed muscle and other soft tissue can be stopped during cut closure, spinal cords are protected from compression, and severe complications such as neural symptoms, paralysis and the like after the laminectomy can be avoided. The artificial vertebral plate is simple in structure, convenient to use, firm in fixation, convenient to dismount and capable of stopping closed muscle and other soft tissue during cut closure, the spinal cords are protected from compression and adhesion, the severe complications such as neural symptoms, paralysis and the like after the laminectomy can be avoided, and the artificial vertebral plate can be implanted in a patient to be used for a long term.

Description

technical field [0001] The invention relates to the medical field, in particular to an artificial lamina used after spinal laminectomy. Background technique [0002] In spinal surgery, it is often necessary to relieve nerve compression and perform laminectomy decompression. After laminectomy, the dural sac or spinal cord will lose the protection of the lamina and be exposed. Since most patients will not have symptoms of spinal cord compression, so the current clinical No measures are taken to protect the spinal cord. However, if the resection of the lamina is relatively large, the exposed area of ​​the spinal cord will also be large. After the operation, the muscles and other soft tissues separated on both sides will close together and press against the spinal cord. In severe cases, paralysis will occur. The technology of total laminectomy for the treatment of spinal stenosis is becoming more and more mature. Some postoperative complications are lamina regeneration and the ...
