Description

Technical Field

[0001] This utility model relates to the field of anterior cervical spine plates, specifically a fracture-resistant anterior cervical spine plate. Background Technology

[0002] Anterior cervical plate, also known as a plate in anterior cervical fixation systems, is a small fixation system typically used after anterior cervical surgery to provide stability to the spine. It can be applied to the anterior part of the spine during surgery to protect bone grafts and provide necessary support and integrity as the spinal structures heal.

[0003] Chinese patent announcement CN208905684U discloses an anterior cervical spine intervention plate. It includes: a plate body with a countersunk hole and a first through hole; an elastic element is installed in the countersunk hole; a fixation element passes through the first through hole, and after the fixation element is fixed, the elastic element blocks the fixation element, preventing it from coming out. This invention solves the problem of loosening and coming out of existing anterior cervical spine intervention plates.

[0004] Existing anterior cervical spine intervention plates are mostly made of steel, which poses a risk of breakage during use, affecting the patient's treatment outcome. Therefore, we propose a breakage-resistant anterior cervical spine intervention plate. Utility Model Content

[0005] The purpose of this invention is to provide a fracture-resistant anterior cervical spine intervention plate to address the problem mentioned in the background art that existing anterior cervical spine intervention plates are mostly made of steel, which poses a risk of fracture during use and affects the treatment effect on patients.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fracture-resistant anterior cervical spine plate, comprising an upper plate and a lower plate, a lower plate with fixing bolts installed above the upper plate and a lower plate with a lower plate installed below the upper plate and a first mounting groove for the lower plate, a reinforcing plate lower plate installed inside the first mounting groove, a second mounting groove for the lower plate, and a sealing silicone lower plate installed on the lower surface of the upper plate and the lower plate.

[0007] Preferably, the upper plate and the lower plate are bolted together by fixing bolts, and the shape and size of the upper plate and the lower plate match the shape and size of the lower plate.

[0008] Preferably, the lower sealing silicone plate is tightly fitted to the lower plate, and the upper plate and lower plate are sealed together by the lower sealing silicone plate.

[0009] Preferably, the shape and size of the lower plate of the reinforcing plate partially match the shape and size of the lower plate of the first mounting groove, and the shape and size of the lower plate of the reinforcing plate partially match the shape and size of the lower plate of the second mounting groove.

[0010] Preferably, the lower plate of the reinforcing plate is made of tungsten metal.

[0011] Compared with the prior art, the present invention provides a fracture-resistant anterior cervical spine plate with the following beneficial effects: the fracture-resistant anterior cervical spine plate improves the overall strength of the steel anterior cervical spine plate by adding a metal reinforcing plate with higher hardness inside, thereby preventing the anterior cervical spine plate from breaking during use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4A fracture-resistant anterior cervical spine support plate includes an upper plate 1, with fixing bolts 2 installed on the top of the upper plate 1 and a lower plate 4 installed below the upper plate 1. The upper plate 1 is bolted to the lower plate 4 via the fixing bolts 2, and the shape and dimensions of the upper plate 1 match those of the lower plate 4. A first mounting groove 6 is formed inside the upper plate 1, and a reinforcing plate 5 is installed inside the first mounting groove 6. The reinforcing plate 5 is made of tungsten metal. A second mounting groove 7 is formed inside the lower plate 4. The shape and dimensions of the reinforcing plate 5 partially match those inside the first mounting groove 6 and partially match those inside the second mounting groove 7. A sealing silicone 3 is installed on the lower surface of the upper plate 1. The sealing silicone 3 is tightly fitted to the lower plate 4, and the upper plate 1 is sealed to the lower plate 4 via the sealing silicone 3. By adding a metal reinforcing plate with higher hardness inside the steel anterior cervical spine support plate, the overall strength of the anterior cervical spine support plate is improved, preventing the anterior cervical spine support plate from breaking during use.

[0019] Working principle: When using this fracture-resistant anterior cervical spine plate, firstly, the reinforcing plate 5 is placed inside the first mounting groove 6 and the second mounting groove 7. Then, four fixing bolts 2 are used to fix the upper plate 1 and the lower plate 4 together. Next, the sealing silicone 3 between the upper plate 1 and the lower plate 4 is used to seal the gap between them. Furthermore, the reinforcing plate 5 can be made of a metal with high hardness such as tungsten or titanium. Users can choose to install a reinforcing plate 5 made of a specific metal according to their needs. Finally, the assembled anterior cervical spine plate is installed on the cervical vertebrae. This is the working principle of the fracture-resistant anterior cervical spine plate.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
