Description

Technical Field

[0001] This utility model relates to the field of angle-adjustable metal bone plates, and more specifically, to an angle-adjustable metal bone plate. Background Technology

[0002] Bone plates are frequently used in fracture surgery. Most existing bone plates are metal plates, designed biomimetic to mimic the shape of human bones, aiming to minimize stress damage caused by bone bending, compression, and rotation. Furthermore, the shape, thickness, screw hole spacing, and hole diameter of the bone plate are predetermined according to the different parts of the body it will be used in. The most common materials used are medical-grade stainless steel and titanium alloy.

[0003] In conventional technologies, such as the Chinese authorized patent CN208464234U (an angle-adjustable metal bone plate), the following is described: A lower bone plate is provided, with two fan-shaped discs at its upper end. A fixed shaft is provided between the two fan-shaped discs. The two ends of the fixed shaft are rotatably connected to the side walls of the fan-shaped discs. A connecting rod is provided on the side wall of the fixed shaft. A hollow sliding groove is provided in the middle of the connecting rod. A limiting rod is provided inside the hollow sliding groove. The side wall of the fan-shaped discs has multiple slots at equal intervals along its circumference that cooperate with the limiting rod. A pull rod is provided perpendicular to the limiting rod on its side wall. The pull rod is fixedly connected to the inner wall of the hollow sliding groove by an elastic device. A fixing rod is provided on the side wall of the pull rod. The fixing rod passes through the hollow sliding groove. A handle is provided at the end of the fixing rod away from the pull rod. An upper bone plate is fixedly connected to the end of the connecting rod away from the fixed shaft.

[0004] According to existing technology, such as the authorization announcement number CN219126631U, this utility model discloses an angle-adjustable metal bone plate, including a second metal bone plate disposed at the upper end of the rear end face of the first metal bone plate. A connecting gear shaft is installed inside the first metal bone plate, and the connecting gear shaft is rotatably connected to the first metal bone plate. This device, by installing a rotation adjustment component to cooperate with the connecting gear shaft, makes it more convenient for the user to adjust the angle of the device, increases the rotation circumference of the device adjustment, and thus achieves a more precise adjustment of the rotation angle of the device, enhancing the convenience of the device. The installation of an electric heating wire can play a heating role, preventing the device from losing heat too quickly when it is in contact with the patient's body, which would cause the patient to feel cold and easily cause discomfort, making the device more humane and enhancing the effect of the device.

[0005] The aforementioned structure features an adjustable angle, but it employs an externally built-in spring-loaded snap-fit ​​assembly for positioning and flipping. In actual use and production, the placement of this elastic snap-fit ​​assembly within the medical bone plate is extremely complex, resulting in poor structural stability, significant mechanical costs, and overall high costs for the bone plate. Utility Model Content

By adopting an overlapping mounting hole position merging structure and setting an angle snap-fit ​​groove box positioning snap-fit ​​block structure, after they are snapped together, the required angle can be adjusted for snap-fit ​​positioning as needed. During fixation, the overlapping mounting hole positions are fixed to the bone with steel nails. After the angle is adjusted, it is firmly positioned and fixed, the angle adjustment is simple, and the cost is low.

[0007] To solve the above problems, the present invention adopts the following technical solution.

By employing a combined structure at the overlapping mounting holes and a structure of angle locking groove and positioning locking block, these components interlock, allowing for adjustment of the required angle for positioning. During fixation, the overlapping mounting holes are fixed to the bone with steel nails. After angle adjustment, the plate is firmly positioned and fixed, resulting in simple angle adjustment and low cost.

[0009] Furthermore, the outer surface of the first metal bone plate is provided with multiple sets of first mounting holes.

[0010] Furthermore, the outer surface of the second metal bone plate is provided with multiple sets of second mounting holes.

[0011] Furthermore, the diameters of the first overlapping mounting hole and the second overlapping mounting hole are the same as the diameters of the first mounting hole and the second mounting hole.

[0012] Furthermore, the angle locking groove adopts a square groove structure, and its positioning locking block adopts a square protruding small block, which is tightly fitted and locked onto the inner surface of the angle locking groove.

[0013] Furthermore, the sixty sets of angle locking grooves are distributed on the surface of the first metal bone plate, and the angle between adjacent angle locking grooves is six degrees.

[0014] Furthermore, the outer surfaces of the overlapping outer ends of the first and second metal bone plates are both rounded.

The outer end of the first metal bone plate body 1 is provided with a first overlapping mounting hole position 4, and the outer surface of the second metal bone plate body 2 is provided with a second overlapping mounting hole position 5. The first overlapping mounting hole position 4 and the second overlapping mounting hole position 5 overlap each other. The upper surface of the first metal bone plate body 1 is provided with an angle locking groove 300, and the lower surface of the second metal bone plate body 2 is provided with a positioning locking block 3. The surface of the first metal bone plate body 1 is provided with a first mounting hole position 40, and the surface of the second metal bone plate body 2 is provided with a second mounting hole position 50. By adopting a combined structure at the overlapping mounting hole positions and setting an angle locking groove and positioning locking block structure, after they are interlocked, the required angle can be adjusted for locking and positioning as needed. During fixation, the overlapping mounting hole positions are fixed to the bone with steel nails. After the angle is adjusted, they are firmly positioned and fixed. The angle adjustment is simple and the cost is low.

[0029] Multiple sets of first mounting holes 40 are distributed on the outer surface of the first metal bone plate 1; this facilitates fixing steel nails to the bone along the first mounting holes 40.

[0030] Multiple sets of second mounting holes 50 are distributed on the outer surface of the second metal bone plate 2; this facilitates fixing steel nails to the bone along the second mounting holes 40.

[0031] The diameters of the first overlapping mounting hole 4 and the second overlapping mounting hole 5 are the same as those of the first mounting hole 40 and the second mounting hole 50. During installation, after the angles of the first metal bone plate 1 and the second metal bone plate 2 are adjusted, steel nails can be inserted through the first overlapping mounting hole 4 and the second overlapping mounting hole 5 to fix them to the bone. The fixation is firm, and the plate can be firmly fixed after the angle is adjusted, without flipping.

[0032] The angle locking groove 300 adopts a square groove structure, and its positioning locking block 3 adopts a square protruding small block. The positioning locking block 3 is tightly fitted and locked onto the inner surface of the angle locking groove 300; the locking is tight and firm, and the angle positioning is stable.

[0033] Sixty sets of angle locking slots 300 are distributed on the surface of the first metal bone plate 1, and the angle between adjacent angle locking slots 300 is six degrees. When adjusting the angle, the positioning locking block 3 can be flexibly locked into the corresponding angle locking slot 300, which makes the angle adjustment convenient and the positioning stable.

[0034] Both the outer surfaces of the overlapping outer ends of the first metal bone plate 1 and the second metal bone plate 2 are rounded; this prevents them from interlocking and squeezing each other during angle adjustment, thus avoiding obstruction.

[0035] In use, the outer end of the first metal bone plate 1 is provided with a first overlapping mounting hole position 4, and the outer surface of the second metal bone plate 2 is provided with a second overlapping mounting hole position 5. The first overlapping mounting hole position 4 and the second overlapping mounting hole position 5 overlap each other. The upper surface of the first metal bone plate 1 is provided with an angle locking groove 300, and the lower surface of the second metal bone plate 2 is provided with a positioning locking block 3. Sixty sets of angle locking grooves 300 are distributed on the surface of the first metal bone plate 1, and the angle between adjacent angle locking grooves 300 is six degrees. When adjusting the angle, the positioning locking block 3 can be flexibly locked into the corresponding angle locking groove 300, which makes angle adjustment convenient and positioning stable. The device employs a square groove structure, with its positioning locking block 3 featuring a square protruding small block. The positioning locking block 3 tightly fits and engages with the inner surface of the angle locking groove 300°. The engagement is tight and secure, ensuring stable angle positioning. During installation, after adjusting the angles of the first metal bone plate 1 and the second metal bone plate 2, steel nails can be inserted along the first overlapping mounting hole position 4 and the second overlapping mounting hole position 5 to fix them to the bone. The fixation is secure, and the plate remains firmly in place after angle adjustment, preventing it from flipping over. Furthermore, steel nails are inserted along the first mounting hole position 40 and the second mounting hole position 50 to fix the plate to the bone. The fixation is secure and stable, and the first metal bone plate 1 and the second metal bone plate 2 remain stable and secure after angle adjustment. The device has a simple structure and low cost.
