Abstract

The invention provides a spinous process vertebral plate replantation internal fixing device. The device is suitable for bone replantation fixation of a spinous process (11) and / or a vertebral plate (12) after intravertebral surgery. The device comprises one or more fixing units, wherein each fixing unit comprises a fixing plate (2), a fixing piece (21) and a bone grafting bin (22); the fixing piece (21) is arranged on the fixing plate (2), and the fixing plate (2) is fixedly connected to the spinous process (11) and / or the vertebral plate (12); and the bone grafting bin (22) is connected to the fixing plate (2). The device has the advantages of simple structure, light weight, small volume and high reliability; through the arrangement of at least three fixing pieces, the fixing effect is effectively improved, and the risk of lateral dislocation of the vertebral plate is reduced; the fixing effect can be further improved by arranging a pedicle screw and / or a facet joint screw; and through the specially-designed reticular bone grafting bin structure, the tissue growth of the operation area can be promoted, and the compression can be reduced.

Description

technical field [0001] The invention relates to the field of surgical devices, in particular to a spinous process lamina replantation internal fixation device. Background technique [0002] Intraspinal tumors are found in any segment of the spinal cord and cauda equina, most commonly in the thoracic segment. It can occur at any age, but adults between the ages of 20 and 40 account for the majority. According to the anatomical site, it is divided into extradural and extramedullary intradural. Intramedullary three categories. According to pathological classification, neurofibroma, meningioma and glioma (including astrocytoma and ependymoma) are the three most common types. Most of the tumors in the spinal canal are benign, and the only effective treatment is surgical resection of the tumor, about 3 / 4 of which can be cured by surgical resection. Even older patients, such as over 70 years old, can sometimes tolerate surgery better. Therefore, we should take a positive attit...
