Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a snap-fit ​​bone plate. Background Technology

[0002] Bone plates, located between the inner and outer periosteum, form compact bone, through which blood vessels pass. Bone plates consist of annular plates and interplates. The annular plates are arranged parallel to the periphery of the bone shaft; the outermost plates are called the outer annular plates, and the innermost plates are called the inner annular plates.

[0003] Currently, fracture-fixation connections are usually made using screws, and this is also the case for fracture connections around the eye. However, the area where holes can be drilled in the bone around the eye is small, and the surrounding load-bearing capacity is reduced after drilling holes and screws are inserted.

[0004] Therefore, we made improvements and proposed a snap-fit ​​bone plate. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a snap-on bone plate.

[0006] This utility model is implemented as follows:

[0007] A snap-fit ​​bone plate includes a pair of snap-fit ​​bodies and a fixed bone plate. The adjacent sides of the pair of snap-fit ​​bodies are respectively connected to the two ends of the fixed bone plate. The pair of snap-fit ​​bodies are an open fixed snap and a closed fixed snap, respectively. The open fixed snap and the closed fixed snap have openings and can undergo elastic deformation.

[0008] Furthermore, the opening and fixing buckle includes a first top cover, a first side corner plate, a first bending and stretching plate, and a first bottom plate; the two ends of the first top cover are respectively connected to the first side corner plate, the ends of the two first side corner plates away from the first top cover and away from the first side corner plate are respectively connected to the first bending and stretching plate, one end of the two first bending and stretching plates is respectively connected to the first bottom plate, and the two first bottom plates are respectively provided with a first inclined surface on an adjacent side, and the two first inclined surfaces are respectively facing the first top cover, and the first side corner plate, the first bending and stretching plate, and the first bottom plate can undergo elastic deformation.

[0009] Furthermore, the closing and fixing buckle includes a second top cover, a second side corner plate, a second bending and stretching plate, and a second bottom plate; the two sides of the second top cover are respectively connected to the second side corner plate, the ends of the two second side corner plates away from the second top cover are respectively connected to the second bending and stretching plate, and the ends of the two second bending and stretching plates away from the second side corner plate are respectively connected to the second bottom plate; the second top cover, the second side corner plate, the second bending and stretching plate, and the second bottom plate can undergo elastic deformation.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, through the connection of the second top cover, the two second side corner plates are connected and maintained in a symmetrical relationship, thus ensuring that the bone plate is subjected to uniform force on the left and right sides. Furthermore, through the connection of the second bending and stretching plate, it is convenient to extend and bend the buckle body to complete the opening and closing action. Furthermore, through the connection of the second bottom plate, it is convenient to fit the bone plate with the other side of the bone, thereby maintaining stability.

[0011] Furthermore, a second inclined surface is provided on each adjacent side of the two second base plates, with the two second inclined surfaces facing the second top cover.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the setting of the second inclined surface facilitates the contact and separation between the bone plate and the bone.

[0013] Furthermore, the fixing bone plate is provided with a plurality of the perforations.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the perforation makes the structure of the plate lighter.

[0015] Furthermore, the perforations are divided into two groups, and the two groups of perforations are staggered.

[0016] The advantage of adopting the above-mentioned further solution is that by utilizing the distribution of perforations, the strength of the plate is kept balanced throughout.

[0017] Furthermore, the bending angle between the first bending tension plate and the second bending tension plate ranges from 90 to 180 degrees.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by limiting the degree of bending of the first bending tension plate and the second bending tension plate, it is beneficial to protect the structure of the bone plate.

[0019] Furthermore, both the buckle body and the fixing plate are made of biodegradable materials.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, by utilizing the properties of biodegradable materials, the bone plate can be free from crevice corrosion and fretting wear after degradation.

[0021] The beneficial effects of this utility model are as follows: By connecting the buckle bodies to both sides of the fixed bone plate and using the identical structure of the two buckle bodies, the bone plate can be used for fixing the eye bone, effectively ensuring the surrounding load-bearing capacity. The buckles clamp the two ends of the bone tissue, avoiding the impact of direct drilling and nailing on strength. The connection of the first top cover connects the two first side plates and maintains a symmetrical relationship, ensuring that the bone plate is evenly stressed from left to right. The connection of the first bending and stretching plate facilitates the extension and bending of the buckle body to complete the opening and closing action. The connection of the first bottom plate facilitates the fitting of the bone plate to the other side of the bone, thereby maintaining stability. The perforation design makes the plate structure lighter, and the distribution of the perforations ensures that the strength of the plate is balanced throughout. Attached Figure Description

The ends of the two first bending and stretching plates 100103 away from the first side corner plate 100102 are respectively connected to the first bottom support plate 100104. The two first bottom support plates 100104 are respectively provided with a first inclined surface 100105 on adjacent sides, and the two first inclined surfaces 100105 face the first top cover. The first side corner plate 100102, the first bending and stretching plate 100103, and the first bottom support plate 100104 can undergo elastic deformation.

[0033] Example 2

[0034] Please see Figure 1-5As an embodiment of this utility model, the closing and fixing buckle 1002 further includes a second top cover 100201, a second side corner plate 100202, a second bending and stretching plate 100203, and a second bottom support plate 100204. The two sides of the second top cover 100201 are respectively connected to the second side corner plate 100202. The ends of the two second side corner plates 100202 away from the second top cover 100201 are respectively connected to the second bending and stretching plate 100203. The ends of the two second bending and stretching plates 100203 away from the second side corner plate 100202 are respectively connected to the second bottom support plate 100204. The second top cover 100201, the second side corner plate 100202, the second bending and stretching plate 100203, and the second bottom support plate 100204 can undergo elastic deformation. The connection of the second top cover 100201 allows the two second side plates 100202 to be connected and maintain a symmetrical relationship, ensuring that the bone plate is subjected to uniform force on both sides. The connection of the second bending and stretching plate 100203 facilitates the extension and bending of the buckle body 100 to complete the opening and closing action.

[0035] Example 3

[0036] Please see Figure 1-5 As an embodiment of this utility model, the fixed bone plate 200 is further provided with a plurality of perforations 2002. The perforations 2002 make the structure of the fixed bone plate 200 lighter. The plurality of perforations 2002 are divided into two groups, and the two groups of perforations 2002 are staggered. By utilizing the distribution position relationship of the perforations 2002, the strength of the fixed bone plate 200 is kept balanced. The bending angle range of the first bending tension plate 100103 and the second bending tension plate 100203 is 90 to 180 degrees. By limiting the bending degree of the first bending tension plate 100103 and the second bending tension plate 100203, it is beneficial to protect the structure of the bone plate. The materials of the buckle body 100 and the fixed bone plate 200 are both biodegradable materials. The biodegradable material is preferably magnesium-aluminum alloy. By utilizing the characteristics of biodegradable materials, the bone plate can be free from crevice corrosion and fretting wear after degradation.

[0037] Specifically, the working principle of this snap-on bone plate is as follows: First, check the structure of the bone plate for integrity. Only after ensuring structural integrity should it be used. The snap-on mechanism clamps the two ends of the bone tissue, preventing direct drilling and impacting strength. Then, the first top cover 100101 connects the two first side plates 100102, maintaining symmetry and ensuring even force distribution on the left and right sides of the bone plate. Finally, the first bending and stretching plate 100103 facilitates the extension and bending of the snap-on body 100, enabling its opening and closing action. The connection of the first support plate 100104 facilitates the fitting of the bone plate to the other side of the bone, thereby maintaining stability. The perforations 2002 make the structure of the fixed bone plate 200 lighter. The distribution of the perforations 2002 ensures that the strength of the fixed bone plate 200 is balanced. At the same time, the positional relationship between the two second support plates 100204 makes the fit between the bone plate and the bone tighter. Furthermore, the biodegradable material properties prevent crevice corrosion and fretting wear after the bone plate degrades.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
