Description

Technical Field

[0001] This utility model relates to the field of titanium plate technology, specifically a novel foldable micro titanium plate for posterior cervical spine dual-channel endoscopy with a single opening. Background Technology

[0002] Posterior cervical spine surgery, due to spinal canal stenosis leading to nerve compression, causes patients to experience pain, numbness, and unsteady gait. In severe cases, it can even cause bowel and bladder dysfunction. When conservative treatment is ineffective or symptoms severely impact daily life, surgical treatment needs to be considered. The core goal of the surgery is to relieve the compression of the spinal cord and create space for nerve recovery. Single-door surgery involves completely cutting the lamina on one side of the spinal cord to release the constriction on the spinal cord. To prevent the lamina from closing, a special single-door titanium plate is used to fix both sides of the cut lamina, maintaining the enlarged spinal foramen space. Because the surgery requires a large space, current single-door surgeries are performed in an open surgical environment. However, minimally invasive surgery has gained more favor among doctors due to its advantages such as smaller incisions, less blood loss, and faster recovery. Therefore, how to perform single-door surgery under minimally invasive surgical conditions is a challenge that doctors and designers need to overcome.

[0003] Because of the unique Z-shaped structure of the single-door panel, the overall size is relatively large, making it difficult to perform surgery under minimally invasive conditions;

[0004] Therefore, a novel posterior cervical spine endoscopic single-door foldable micro-titanium plate is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel posterior cervical spine dual-channel endoscopic single-door foldable micro titanium plate to solve the problem mentioned in the background art that the Z-shaped titanium plate is too large to be convenient for minimally invasive surgery.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel posterior cervical spine dual-channel endoscopic single-door foldable micro titanium plate, comprising a first micro titanium plate and a second micro titanium plate. The top of the first micro titanium plate is provided with a foldable micro titanium plate assembly, which includes a positioning platform, a positioning groove, a rotating shaft, a connecting platform, and a second micro titanium plate. The positioning platform is fixed to the left side of the top of the first micro titanium plate, and the positioning platform is provided with a positioning groove. The rotating shaft is movably installed inside the positioning groove, and the connecting platform is fixed to the outer wall of the rotating shaft. The second micro titanium plate is fixed to the right side of the connecting platform.

[0007] As a further technical solution of this utility model, two sets of positioning platforms are fixed on the left side of the top of the first micro titanium plate, and the two sets of positioning platforms are symmetrically distributed.

[0008] As a further technical solution of this utility model, a first through groove is provided through the surface of the top end of the second micro titanium plate, and a second through groove is provided through the surface of the top end of the first micro titanium plate.

[0009] As a further technical solution of this utility model, a connecting plate is fixed to the right side of the first micro titanium plate, and a reinforcing rib is fixed to the right side of the connecting plate.

[0010] As a further technical solution of this utility model, the front end of the reinforcing rib is fixed with a first fixing platform, and the top end of the first fixing platform is provided with a first screw hole.

[0011] As a further technical solution of this utility model, a second fixing platform is fixed to the rear end of the reinforcing rib, and a second screw hole is provided through the top end of the second fixing platform.

[0012] As a further technical solution of this utility model, an extension plate is fixed to the right side of the second micro titanium plate, and a third fixing platform is fixed to the right side of the extension plate. A third screw hole is provided through the top surface of the third fixing platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting a rotating shaft, the complete "Z"-shaped titanium plate is divided into two halves from the center position, namely the first micro titanium plate and the second micro titanium plate. With the assistance of the positioning platform and the rotating shaft, they are movably connected. When folded, the size of the plate is reduced, making it convenient to insert under the channel, thus realizing the convenience of the micro titanium plate insertion method.

[0014] By providing a first through groove and a second through groove, which are located on the surfaces of the first and second micro titanium plates respectively, the overall weight is reduced. The first and second through grooves can also assist in the insertion of screws for adaptive positioning, thereby enhancing the stability of the micro titanium plate during use.

[0015] By setting a first fixing platform, a second fixing platform, and a third fixing platform, which are respectively located on the first micro titanium plate and the second micro titanium plate, and staggered from each other when folded, a single set of screws can be installed. Then, by flipping the folded side inside the body, the screws on the vertebral plate side can be fixed, thus achieving the convenience of fixing the micro titanium plate. Attached Figure Description
