Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a straight metal bone plate. Background Technology

[0002] Metal bone plates are surgical instruments used for fracture fixation, typically made of metal materials such as stainless steel or titanium alloys. Their primary function is to promote bone healing by fixing the fracture site. Bone plates are usually used in conjunction with screws to securely connect the fractured bone ends together.

[0003] A search revealed that Chinese Publication No. CN204971543U discloses a straight metal bone plate, belonging to the field of orthopedic medical devices. It includes a steel plate and a sleeve disposed at the end of the steel plate. The sleeve has a through hole arranged axially along the sleeve. The end of the through hole closer to the steel plate is the proximal end, and the end farther from the steel plate is the distal end. The distal end of the through hole has no threads, while the proximal end has a threaded area with a T-shaped structure. A limiting screw is threaded into the threaded area. This utility model has a simple structure. The threaded area at the proximal end of the through hole, with a limiting screw threaded into it, effectively prevents the tension screw from loosening, shifting, or even dislodging, resulting in good bone healing and high safety in clinical use.

[0004] While the aforementioned patent can effectively prevent the tension screws from loosening, shifting, or even coming out, the bone plate fixation is not adjustable, making it unable to fully adapt to the specific situation of patients with different bone lengths. This fixation method lacks flexibility, hence the proposal of a straight metal bone plate to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a straight metal bone plate, which aims to improve the problem that the existing bone plate fixation cannot be adjusted, making it unable to fully adapt to the specific situation of patients when facing skeletons of different lengths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A straight metal bone plate includes a plate body one and a plate body two. Both ends of the plate body one and the plate body two are equipped with a connecting adjustment mechanism, and the top of the plate body one and the plate body two are equipped with a fixing mechanism. The connection adjustment mechanism includes four adjustment plates, which are respectively installed on the two ends of the plate body one and the plate body two on the same side. The two adjustment plates are threadedly connected to the same side, and hexagonal bolts are fixedly connected to the outside of the adjustment screws. The top of the plate body one and the plate body two are provided with mounting components. Through the above technical solution: the straight metal bone plate achieves multi-angle fixation and support through the double-plate design of plate body one and plate body two. The connecting adjustment mechanism consists of four adjustment plates, which are installed on the adjacent sides of the two plates. The two are connected by adjustment screws. The rotation of the adjustment screws drives the movement of the adjustment plates, thereby dynamically adjusting the distance between the plates to adapt to different bone types. The top fixation mechanism provides further stability through the installation components, ensuring that the bone plate can effectively fix the bone after implantation and promote structural support and load distribution during the healing process.

[0007] As a further description of the above technical solution: The mounting assembly includes multiple mounting bolts, and multiple mounting slots are provided on the top of the first plate and the second plate. The outer parts of the mounting bolts are mounted on the inner wall of the mounting slots. The above technical solution involves externally mounting bolts on the inner wall of the mounting groove, creating a stable connection between the plates and ensuring that the bone plate provides reliable support and fixation during surgery.

[0008] As a further description of the above technical solution: The fixing mechanism includes multiple rotating plates, one side of which is rotatably connected to one side of the mounting groove, and a trapezoidal groove is formed on the outside of the rotating plate. The above technical solution achieves stable locking through multiple rotating plates. One side of the rotating plate is rotatably connected in the mounting groove, and the outside is provided with a trapezoidal groove. The trapezoidal groove cooperates with other components and achieves a tight fit through rotation, ensuring that the bone plate is firmly fixed during use and preventing loosening.

[0009] As a further description of the above technical solution: The adjusting plate is externally threaded with a rotating pin, and the external thread of the rotating pin is connected to the inner walls of the first plate and the second plate. Through the above technical solution, this design can lock the adjustment plate and the plate body together, ensuring stability during adjustment and allowing precise control of the spacing between the plates.

[0010] As a further description of the above technical solution: Multiple mounting slots are evenly distributed on the top of plate one and plate two, and the mounting bolts are externally slidably connected to the inner wall of the mounting slots; The above technical solution allows the installation bolts to be flexibly adjusted in position during surgery to adapt to different bone structures, ensuring stable fixation and precise support.

[0011] As a further description of the above technical solution: The top of the mounting bolt is threaded with a trapezoidal block, and the outside of the trapezoidal block is in contact with the inner wall of the trapezoidal groove. Through the above technical solution, this design ensures that the trapezoidal block is stably locked in the trapezoidal groove, effectively preventing the displacement of the installation bolts and enhancing the fixation and stability of the bone plate.

[0012] As a further description of the above technical solution: The other end of the rotating plate engages with the inner wall of the mounting groove, and the top of the mounting bolt has a star-shaped groove. The above technical solution provides additional gripping surfaces through the star-shaped grooves on the top of the mounting bolts, facilitating manual adjustment and ensuring the stability of the rotating plate during adjustment, thereby enhancing the fixation and operational flexibility of the bone plate.

[0013] As a further description of the above technical solution: The external thread of the mounting bolt is connected to the inner wall of the mounting groove and passes through one side of the first plate and the second plate. The above technical solution ensures that the mounting bolts can firmly connect the two plates together, providing effective support and stability, and enhancing the overall structural strength and reliability of the bone plate.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the cooperation of the adjusting plate and the rotating pin allows the first plate and the second plate to be flexibly adjusted after fixation, thereby adapting to skeletons of different lengths and shapes. The rotation of the adjusting screw can precisely control the movement of the adjusting plate and adjust the distance between the plates, thereby ensuring that the spacing between the first plate and the second plate is suitable for the patient's specific fracture condition. This design provides higher adaptability and adjustability, enabling precise fixation in different fracture types and joint positions, optimizing surgical results and promoting better bone healing, and improving the flexibility of use.

[0015] 2. In this utility model, the precise fixation and stability are achieved through the cooperation of the mounting bolt and the trapezoidal groove. By rotating the rotating plate, the trapezoidal groove comes into contact with the trapezoidal block, restricting the movement of the trapezoidal block, thereby effectively fixing the position of the mounting bolt and preventing it from loosening or shifting. This structure enhances the fixation effect, ensures the stability of the mounting bolt in the skeleton, avoids insecure fixation due to position changes, and thus improves the accuracy and reliability of fracture repair, ensuring a stable treatment effect after surgery.

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.

[0019] Reference Figures 1 to 3 An embodiment of this utility model is provided: a straight metal bone plate, including a plate body 1 and a plate body 2. The double plate design achieves multi-angle fixation support. Both ends of the plate body 1 and the plate body 2 are equipped with a connecting adjustment mechanism 3, which can realize dynamic adjustment of the distance between the two plates. The top of the plate body 1 and the plate body 2 are equipped with a fixing mechanism 5 to enhance the overall stability after implantation. The connecting adjustment mechanism 3 includes four adjustment plates 31, forming a symmetrical bidirectional adjustment structure. The four adjustment plates 31 are respectively installed on the two ends of the adjacent side of the plate body 1 and the plate body 2 to ensure the synchronous adjustment function on both sides. The adjacent side of the two adjustment plates 31 is threaded with adjustment screws 32, which realize precise displacement control through screw transmission. The external fixed connection of the adjustment screws 32 is a hexagonal bolt 33, which provides a standard torque input interface. The external thread of the adjustment plate 31 is connected with a rotating pin 34, which has the dual functions of positioning and axial fixation. The external thread of the rotating pin 34 is connected to the inner wall of the plate body 1 and the plate body 2, forming a three-point mechanical locking structure. The top of the plate body 1 and the plate body 2 is provided with an installation component 4 to realize multi-point dynamic anchoring with the bone surface. Specifically, the straight metal bone plate, through its double-plate design, including plate 1 and plate 2, provides multi-angle fixation support, achieving precise bone alignment and stable repair. Its connection adjustment mechanism 3 consists of four adjustment plates 31, employing a symmetrical bidirectional adjustment structure to ensure uniformity and balance in adjustment. The adjustment screws 32, through a helical transmission mechanism, achieve precise control of the distance between the two plates, dynamically adapting to the healing needs of the bone. External adjustments are made by inputting standard torque through hexagonal bolts 33, ensuring the accuracy and safety of operation. The design of the rotating pin 34 achieves the dual functions of positioning and axial fixation, effectively resisting plate displacement. The three-point mechanical locking structure forms a stable fixation relationship between plate 1 and plate 2, enhancing the overall structural resistance and preventing postoperative displacement. The top mounting component 4 achieves multi-point dynamic anchoring with the bone surface, further dispersing local stress, improving the repair effect, and ensuring the stability of the biomechanical environment of the bone during the healing process.

[0020] Mounting assembly 4 includes multiple mounting bolts 41, which are precisely designed to be flexibly adjustable in different positions, thus providing a variety of options for fixing the bone plate. Multiple mounting grooves 42 are provided on the top of plate 1 and plate 2. The even distribution of these mounting grooves 42 ensures that the bone plate can provide optimal support in various application scenarios and adapt to the needs of different positions and angles. The external threads of the mounting bolts 41 are connected to the inner wall of the mounting grooves 42 and penetrate one side of plate 1 and plate 2, effectively fixing the two plates together and ensuring stability and strength throughout the healing process. Multiple mounting slots 42 are evenly distributed on the top of plate 1 and plate 2, providing a modular fixation option. This allows doctors to select the optimal installation position based on the specific situation of bone injury. The external sliding connection of the mounting bolt 41 is to the inner wall of the mounting slot 42. This design allows for quick position adjustment during surgery, ensuring the convenience and flexibility of surgical operation. The external mounting of the mounting bolt 41 to the inner wall of the mounting slot 42 forms a stable connection, enhancing the overall strength of the bone plate. refer to Figure 4 The fixing mechanism 5 includes multiple rotating plates 51, which are designed to be locked quickly and effectively during installation. The other end of the rotating plate 51 engages with the inner wall of the mounting groove 42, ensuring the stability of the rotating plate 51 during use. The top of the mounting bolt 41 is provided with a star-shaped groove, which increases the gripping surface during adjustment, thereby improving the convenience and efficiency of manual adjustment. One side of the rotating plate 51 is rotatably connected to one side of the mounting groove 42. The design takes into account the smoothness of operation and avoids structural instability caused by improper operation. The rotating plate 51 has a trapezoidal groove 52 on its outside. This design allows for effective adjustment of the tightness of the fit when the plate moves. The top of the mounting bolt 41 is threaded with a trapezoidal block 53. Through the configuration of the trapezoidal block 53, automatic locking can be achieved during rotation to prevent the mounting bolt 41 from being accidentally displaced during use. The outside of the trapezoidal block 53 contacts the inner wall of the trapezoidal groove 52, ensuring a stable connection between the two and enhancing the reliability of the installation. Overall, this structure achieves a highly efficient and stable bone fixation effect by combining multiple mechanical principles, providing an excellent support environment for bone healing. Specifically, the mounting component 4 achieves flexible fixation through multiple mounting bolts 41, adapting to different bone injury conditions to provide optimal support. The mounting bolts 41 connect with multiple mounting slots 42 on plate 1 and plate 2, allowing for quick adjustment of the installation position during surgery, ensuring convenience and flexibility. This design effectively enhances the overall strength of the bone plate and ensures stability during the healing process. The fixation mechanism 5 utilizes multiple rotating plates 51, whose stable design allows for rapid locking, enhancing stability during use. The engagement of the rotating plates 51 with the mounting slots 42, combined with the cross-shaped groove design, increases the gripping area, thereby improving the efficiency of manual adjustment. The combination of the trapezoidal groove 52 and the trapezoidal block 53 achieves automatic locking through rotation, effectively preventing accidental displacement of the mounting bolts 41 and ensuring the stability and reliability of the entire system. Through coordinated work, the overall structure achieves excellent bone fixation and promotes bone healing.

[0021] Working principle: When plate 1 and plate 2 are needed, the adjusting plate 31 is aligned with one side of plate 1 and plate 2, and the rotating pin 34 is threaded into the inner wall of the adjusting plate 31. After adjusting the position of plate 2 to that of plate 1 in advance, the rotating pin 34 is threaded into the inner wall of plate 1 and plate 2 to complete the fixation and connection. Then, by rotating the hexagonal bolt 33, the adjusting screw 32 can be rotated. The rotation of the adjusting screw 32 can rotate the inner wall of the adjusting plate 31, thereby controlling the movement of the two adjusting plates 31 outside the adjusting screw 32. The movement of the adjusting plates 31 can control the distance between plate 1 and plate 2, adapting to the specific joints of different parts. Then, by moving the mounting bolt 41 to different positions in the mounting groove 42, the mounting bolt 41 is installed into the frame. Finally, the rotating plate 51 is rotated, which causes the trapezoidal groove 52 to move. As the trapezoidal groove 52 moves, it can contact the trapezoidal block 53 at the bottom, thereby restricting the trapezoidal block 53. When the trapezoidal block 53 is restricted, the mounting bolt 41 is also restricted, thus stabilizing the mounting bolt 41 and preventing the position of the mounting bolt 41 from moving.
