Vertebral plate steel plate for cervical vertebral body

Abstract

The invention discloses a vertebral plate steel plate for cervical vertebral body, which is provided with a gripping end, wherein the gripping end is provided with an upper gripping plate and a lower gripping plate for gripping the cut end of the vertebral plate, and the gripping end is also provided with a retaining block to be retained into a groove at the port of the vertebral plate cut end. Under the gripping effects of the upper gripping plate and the lower gripping plate, the vertebral plate can not move up and down relative to the vertebral plate steel plate; simultaneously, because the retaining block can be inserted into the groove at the port of the vertebral plate cut end, the front and back side walls of the groove are abutted against the retaining block, so that the vertebral plate can not swing back and forth relative to the vertebral plate steel plate; and in addition, because the cut end of the vertebral plate is pushed open outwards and has a certain resetting trend, the cut end of the vertebral plate is not liable to disengage from the side. Therefore, the vertebral plate steel plate of the structure can position the cut end of the vertebral plate between the upper gripping plate and the lower gripping plate more reliably before setscrews are implanted, and moreover, the retaining block is helpful to strengthen the fixation of the setscrews after the setscrews are implanted.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a vertebra plate for cervical vertebral body. Background technique [0002] When the cervical spine is damaged, the spinal cord in the cervical spine may be damaged, and the damaged spinal cord may compress the cervical nerves, causing discomfort, pain and other symptoms for the patient. For example, fracture and dislocation of the cervical spine accompanied by spinal cord injury, a fracture block in the spinal canal of the cervical spine that obviously compresses the spinal cord, and symptoms of spinal cord injury gradually aggravate after injury may all cause cervical nerve compression. [0003] During clinical surgical treatment, steps such as incision, exposure, laminectomy, fusion and fixation after resection, and incision closure are usually performed. In the prior art, laminectomy mainly includes total laminectomy, extended laminectomy, and unilateral laminectomy. The f...

Problems solved by technology

[0007] However, the above-mentioned fixation technique has the following technical problem: when inserting the lamina plate 11, one end of the lamina plate 11 and the lamina 102 are only positioned by clamping up and down, so as to facilitate the implantation of fixation screws, and this method is stable. Poor stability, the lamina plate 11 is easy to fall off from the openings on both sides of the accommodation port, and separated from the lamina 11, it is not easy to operate during the operation, and the postoperative stability cannot be guaranteed only by fixing screws; in addition, the upper splint 111 is separated from the lower splint 112, which has poor strength and weak pressure bearing capacity
