A screwless anterior cervical spine fixation plate and fixation method thereof

Abstract

The invention relates to a screwless cervical spine anterior fixation plate and a fixation method thereof. So far, the plate screw system contains at least 4 screws, and any screw loosening or falling out will lead to surgical failure, and the incidence rate is also between 1% and 3%. The distance between the screw and the fixed plate and the lower edge has It may affect the motor function of adjacent segments, and even cause early degeneration; the fixation process takes a long time, which increases the risk of surgical complications such as infection. The central position of the fixed plate of the present invention is provided with a lookout hole, the fixed plate is provided with plate-shaped nails, and the fixed plate and the plate-shaped nails are of an integrated structure. The present invention does not have screws, and the inherent plate-like nails are provided with serrated hooks, which eliminates the complications of screw loosening or prolapse; the fixing plate and the plate-like nails are integrated, shortening the length of the plate and reducing the impact on adjacent segments. Possibility of impact; the simplification of operation steps shortens the operation time and reduces the complications such as infection caused by prolonged exposure time.

Description

technical field [0001] The invention belongs to orthopedic surgery, and in particular relates to a screwless anterior cervical vertebra fixation plate and a fixation method thereof. Background technique [0002] Anterior cervical decompression and fusion are commonly used surgical methods in spine departments. Since the invention of the Gaspar anterior cervical plate and screw system in 1991, after anterior cervical decompression and fusion, the stability has been achieved immediately, allowing patients to get out of bed early , improved the fusion rate and treatment effect, and then the locking screw system, etc., are all trying to prevent the screw from coming out. However, the plate screw system still has the following problems so far: 1. Each fixation system has at least Contains 4 screws, any screw loosening or falling out will lead to surgical failure, the incidence rate is also between 1% and 3%, and there is still no improved product; 2. The distance between the scre...
