Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a surgical bone plate that is easy to assemble. Background Technology

[0002] Surgical bone plates are orthopedic instruments used to fix fracture sites and promote fracture healing. Bone plates are usually made of metal materials, such as stainless steel and titanium alloys, which have good biocompatibility and corrosion resistance. The shape and size of bone plates vary depending on the location and type of fracture, and they can be made into strip, Y-shape, L-shape, T-shape, etc., depending on the purpose.

[0003] Because each patient's fracture is different, and existing bone plates have fixed structures and numerous length specifications, it is often necessary to stock all available plates to meet surgical needs. This leads to a large workload for inventory and acceptance, high sterilization costs, slow selection during surgery, and poor versatility as standard-sized bone plates cannot be flexibly adjusted to accommodate individual patient differences. Furthermore, regardless of whether the bone plate is straight, anatomical, or angled, it requires pre-shaping, resulting in preparation time for plate insertion and delaying patient treatment. Additionally, the shaped bone plate may not have sufficient contact surface between the plate surface and the bone. Therefore, we propose a new surgical bone plate that is easy to assemble. Utility Model Content

[0004] The main objective of this invention is to provide a surgical bone plate that is easy to assemble, which can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a surgical bone plate that is easy to assemble, comprising: a first bone plate and a second bone plate, the first bone plate and the second bone plate being symmetrically arranged, a plurality of first docking cylinders and second docking cylinders being fixedly connected to the sides of the first bone plate and the second bone plate that are close to each other, the first docking cylinders and the second docking cylinders being spaced apart, and the first docking cylinders and the second docking cylinders being fixedly connected by a first meshing tooth post; a third bone plate, the bottom of the third bone plate being fixedly connected to a connecting cylinder, the top and bottom of the first bone plate and the second bone plate being fixedly connected to fixing blocks, the connecting cylinders and the fixing blocks being fixedly connected by fixing components, and the unused fixing blocks being fixedly connected to a protective cover by a second fixing bolt.

[0006] As a further description of the above technical solution, the inner cavities of the first docking cylinder and the second docking cylinder are respectively provided with a first meshing groove, and the first meshing groove is meshed with the first meshing tooth column.

[0007] As a further description of the above technical solution, an installation head is fixedly connected to one end of the first meshing tooth post, and a fixing plate is fixedly connected to one side of the installation head. A through arc-shaped groove is opened on the top of the fixing plate, and threaded holes are opened on the top of the first bone plate and the bottom side of the second bone plate, respectively. The arc-shaped groove and the threaded hole are fixedly connected by a first fixing bolt.

[0008] As a further description of the above technical solution, the top of the fixing block has a through groove, and the bottom of the through groove is fixedly connected to a second meshing tooth column. The bottom of the connecting cylinder has a second meshing groove, and the second meshing groove meshes with the second meshing tooth column.

[0009] As a further description of the above technical solution, the sidewall of the through groove is symmetrically provided with mounting grooves, the inner cavity of the mounting groove is provided with a fixing component, and the middle of the sidewall of the connecting cylinder is provided with an annular fixing groove.

[0010] As a further description of the above technical solution, the fixing component includes a spring, a movable plate, a fixing block, and a limiting ring. The spring is fixedly connected to the inner wall of the mounting groove. One end of the spring is fixedly connected to the movable plate. One side of the movable plate is fixedly connected to the fixing block. The fixing block is engaged with the annular fixing groove. The opening of the mounting groove is fixedly connected to the limiting ring. The fixing block is slidably connected to the inner cavity of the limiting ring.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the angles of the first and second bone plates are adjusted before the bone-setting surgery. Pre-shaping of the bone plates is unnecessary; the shaping is achieved through the engagement of the first meshing tooth post and the first meshing tooth groove. This ensures sufficient bone-setting surface while significantly shortening pre-operative preparation time and accelerating the patient's treatment process. Furthermore, depending on the patient's fracture condition, the first and second bone plates can be fitted onto one bone, while the third bone plate is fixed to another bone. The third bone plate is then fixed to a corresponding fixation block for bone setting, allowing for flexible adjustment and excellent bone-setting results. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figure 1-4This utility model provides a technical solution: a surgical bone plate that is easy to assemble, comprising: a first bone plate 1 and a second bone plate 3, the first bone plate 1 and the second bone plate 3 being symmetrically arranged, and a plurality of first connecting cylinders 2 and second connecting cylinders 4 being fixedly connected to the sides of the first bone plate 1 and the second bone plate 3 that are close to each other, the first connecting cylinders 2 and the second connecting cylinders 4 being spaced apart, and the first connecting cylinders 2 and the second connecting cylinders 4 being fixedly connected by a first meshing tooth post 5; a third bone plate 12, the bottom of the third bone plate 12 being fixedly connected to a connecting cylinder 15, and the top of the first bone plate 1 and the second bone plate 3 being... The top and bottom are respectively fixedly connected to fixing blocks 11. The connecting cylinder 15 and the fixing blocks 11 are fixedly connected by fixing components. The empty fixing blocks 11 are fixedly connected to the protective cover 23 by the second fixing bolt 24. When in use, depending on the patient's fracture condition, it is selected whether to use the third bone plate 12. On the fixing blocks 11 that do not need to be connected to the third bone plate 12, the protective cover 23 is fixedly clipped to the fixing blocks 11 and the two are fixedly connected by the second fixing bolt 24. This can cover the second meshing tooth column 14, fixing components, etc., so that the surface of the bone plate remains flat and avoids discomfort during use.

[0018] Specifically, such as Figure 2 , Figure 4 As shown, the inner cavities of the first docking cylinder 2 and the second docking cylinder 4 are respectively provided with the first meshing groove 6. The first meshing groove 6 is meshed with the first meshing tooth post 5. In use, firstly, the first docking cylinder 2 on the first bone plate 1 and the second docking cylinder 4 on the second bone plate 3 are inserted together. Then, the first bone plate 1 and the second bone plate 3 are rotated to determine the angle. The two first meshing tooth posts 5 are inserted into the inner cavities of the first docking cylinder 2 and the second docking cylinder 4 from both ends and fixed.

[0019] Specifically, such as Figure 3As shown, a mounting head 7 is fixedly connected to one end of the first meshing tooth post 5, and a fixing plate 8 is fixedly connected to one side of the mounting head 7. A through arc-shaped groove 9 is opened on the top of the fixing plate 8. Threaded holes are opened on the top of the first bone plate 1 and the bottom side of the second bone plate 3 respectively. The arc-shaped groove 9 and the threaded hole are fixedly connected by the first fixing bolt 10. When using this bone plate, first determine the curvature of the bone setting surface of the patient's bone. Then, rotate the first bone plate 1 and the second bone plate 3. Using an angle measuring tool such as a graduated ruler or graduated instrument, rotate the first bone plate 1 and the second bone plate 3 to form a suitable included angle. Next, insert the two first meshing toothed pillars 5 into the inner cavities of the first connecting cylinder 2 and the second connecting cylinder 4 from both ends, and engage with the first meshing grooves 6 in the inner cavities of the first connecting cylinder 2 and the second connecting cylinder 4. This locks the first connecting cylinder 2 and the second connecting cylinder 4 together with the first meshing toothed pillars 5, preventing relative rotation. Finally, fix the first fixing plate 10 to the side wall of the first bone plate 1 or the side wall of the second bone plate 3 using the first fixing bolts 10. This fixes the first meshing toothed pillars 5, and the surgery can then begin. During the surgery, bone screws are passed through the bone screw holes on the first bone plate 1 and the second bone plate 3 to fix the first bone plate 1 and the second bone plate 3 to the patient's bone. There is no need to pre-shape the bone plates, which greatly shortens the preparation time before bone setting surgery and speeds up the treatment process for the patient.

[0020] Specifically, such as Figure 3 , Figure 4 As shown, the top of the fixing block 11 has a through groove 13, and the bottom of the through groove 13 is fixedly connected to the second meshing tooth post 14. The bottom of the connecting cylinder 15 has a second meshing groove 16, and the second meshing groove 16 is meshed with the second meshing tooth post 14.

[0021] The sidewall of the through groove 13 has symmetrically opened mounting grooves 17, and the inner cavity of the mounting groove 17 is provided with a fixing component. The middle of the sidewall of the connecting cylinder 15 has an annular fixing groove 22.

[0022] The fixing assembly includes a spring 18, a movable plate 19, a fixing block 20, and a limiting ring 21. The spring 18 is fixedly connected to the inner wall of the mounting groove 17. One end of the spring 18 is fixedly connected to the movable plate 19, which is slidably connected to the inner wall of the mounting groove 17. The fixing block 20 is fixedly connected to one side of the movable plate 19. One side of the fixing block 20 is trapezoidal and engages with the annular fixing groove 22. The limiting ring 21 is fixedly connected to the opening of the mounting groove 17, and the fixing block 20 is slidably connected to the inner cavity of the limiting ring 21. The limiting ring 21 provides good limiting and guiding function for the movable plate 19 and the fixing block 20. When the angle between the first bone plate 1 and the second bone plate 3 is determined, the location of the patient's fracture can be considered to determine whether a third bone plate 12 needs to be connected. When the third bone plate 12 is needed to fix the patient's bone, the first bone plate 1 and the second bone plate 3 are first fixed to one of the patient's bones with bone screws, and then the third bone plate 12 is fixed to the other bone of the patient with bone screws. At this time, the connecting sleeve 15 on one side of the third bone plate 12 is inserted into the cavity of the through groove 13 on the selected fixing block 11. At this time, the second engagement groove 16 in the cavity of the connecting sleeve 15 engages with the second engagement tooth 14 in the cavity of the through groove 13, thereby connecting the third bone plate 12. Plate 12 and fixing block 11 are locked together without relative rotation. As the connecting cylinder 15 continues to penetrate deeper, the side wall of the connecting cylinder 15 presses against the inclined side wall of the fixing block 20, causing the fixing block 20 to move into the inner cavity of the mounting groove 17 and push the moving plate 19 to compress the spring 18. When the annular fixing groove 22 moves to the position of the mounting groove 17, the spring 18 releases its elastic force, pushing the moving plate 19 and the fixing block 20 into the inner cavity of the through groove 13, so that the fixing block 20 is engaged with the inner cavity of the annular fixing groove 22, thus fixing the connecting cylinder 15. Assembly is convenient and quick, without the need for tools, which greatly improves the efficiency of bone plate assembly, and the adjustment is flexible with good bone setting effect.

[0023] It should be noted that this utility model is a surgical bone plate that is easy to assemble. When using this bone plate, first determine the curvature of the bone joint surface of the patient's bone, then rotate the first bone plate 1 and the second bone plate 3. With the help of angle measuring tools such as a graduated ruler or graduated instrument, rotate the first bone plate 1 and the second bone plate 3 to form a suitable included angle. Then, insert the two first meshing toothed columns 5 into the inner cavity of the first docking cylinder 2 and the second docking cylinder 4 from both ends, and mesh with the first meshing groove 6 in the inner cavity of the first docking cylinder 2 and the second docking cylinder 4. This locks the first docking cylinder 2 and the second docking cylinder 4 together with the first meshing toothed columns 5 so that they will not rotate relative to each other. Finally, fix the first fixing bolt 10 and the fixing plate 8 to the side wall of the first bone plate 1 or the side wall of the second bone plate 3 to fix the first meshing toothed columns 5, and then the operation can begin. During the surgery, bone screws are passed through the screw holes on the first bone plate 1 and the second bone plate 3 to fix them to the patient's bones. There is no need to pre-shape the bone plates, which greatly shortens the preparation time before bone setting surgery and speeds up the treatment process for the patient.

[0024] When the angle between the first bone plate 1 and the second bone plate 3 is determined, the location of the patient's fracture can be considered to determine whether a third bone plate 12 needs to be connected. When the third bone plate 12 is needed to fix the patient's bone, the first bone plate 1 and the second bone plate 3 are first fixed to one of the patient's bones with bone screws, and then the third bone plate 12 is fixed to the other bone of the patient with bone screws. At this time, the connecting sleeve 15 on one side of the third bone plate 12 is inserted into the cavity of the through groove 13 on the selected fixing block 11. At this time, the second engagement groove 16 in the cavity of the connecting sleeve 15 engages with the second engagement tooth 14 in the cavity of the through groove 13, thereby connecting the third bone plate 12. Plate 12 and fixing block 11 are locked together without relative rotation. As the connecting cylinder 15 continues to penetrate deeper, the side wall of the connecting cylinder 15 presses against the inclined side wall of the fixing block 20, causing the fixing block 20 to move into the inner cavity of the mounting groove 17 and push the moving plate 19 to compress the spring 18. When the annular fixing groove 22 moves to the position of the mounting groove 17, the spring 18 releases its elastic force, pushing the moving plate 19 and the fixing block 20 into the inner cavity of the through groove 13, so that the fixing block 20 is engaged with the inner cavity of the annular fixing groove 22, thus fixing the connecting cylinder 15. Assembly is convenient and quick, without the need for tools, which greatly improves the efficiency of bone plate assembly, and the adjustment is flexible with good bone setting effect.
