Description

Technical Field

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

[0002] Metal bone plates are used on bone plates from various parts of the body. They are mainly divided into locking metal bone plates and ordinary metal bone plates (including anatomical, straight, and angular types). The main difference between the two lies in the holes in the bone plates. Locking metal bone plates have threads in the holes, which are locked in place with the threads of screw heads for stable internal fixation. Ordinary metal bone plates have round, unthreaded holes, which are fixed by compression with ordinary ball-head screws.

[0003] A search revealed Chinese patent publication number CN217793296U, which discloses an angled metal bone plate, comprising a fixation plate, a first sub-plate, and a second sub-plate. The fixation plate is provided with fixation holes and connection holes. Both the first and second sub-plates are detachably mounted on the bottom of the fixation plate, and the first and second sub-plates are located within the distance between adjacent connection holes. The second sub-plate is arranged in an "I" shape. This application can reduce the overall weight of the bone plate while ensuring its effectiveness, thus improving the problem of increased patient load and poor experience caused by large-area fixation bone plates.

[0004] The aforementioned patent mentions the beneficial effects of "detachably setting first and second auxiliary plates of different shapes on the fixation plate of a traditional bone plate. The special shape can be selected and fixed according to the shape and location of the bone fracture. This method can reduce the overall weight of the bone plate and reduce the burden on the patient while ensuring the bone healing effect." Although the aforementioned patent can reduce the overall weight of the bone plate, in the existing technology, some bone plates are connected by bolts and nuts. Doctors need to spend more time removing the bone plates, which will prolong the operation time. Prolonged operation increases the patient's anesthesia risk and is prone to anesthesia-related complications, such as delayed awakening and respiratory depression. For doctors, prolonged high-intensity operation will exacerbate their fatigue and affect the accuracy of operation in the later stage of the operation. Therefore, the angled metal bone plate is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an angled metal bone plate, which aims to improve the problem that some bone plates in the prior art are difficult to remove, resulting in prolonged operation time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An angled metal bone plate includes a bone plate body, the bone plate body having multiple internal cavities, a support column rotatably connected inside each cavity, two rotating plates rotatably connected outside each support column, a telescopic component fixedly connected to the bottom inner wall of each cavity, multiple sleeve columns fixedly connected to the bottom of each bone plate body, grooves being formed on both the left and right sides of each sleeve column, and a limit component slidably connected inside each cavity. Through the above technical solution: the angled metal bone plate achieves reliable fixation and convenient removal of the fracture site, the support column provides a fulcrum for the rotation of the plate, the telescopic component assists the movement of the plate and ensures reversible operation, and the limiting component controls the rotation of the plate under the pull of the pull rod, so that it cooperates with the groove of the sleeve column to complete the fixation and separation of the bone plate at the bone, thus meeting the surgical requirements.

[0007] As a further description of the above technical solution: The telescopic assembly includes an arc-shaped rod, the bottom of which is fixedly connected to the bottom inner wall of the inner cavity, and a spring is sleeved on the outside of the arc-shaped rod; Through the above technical solution, the telescopic component realizes the elastic assistance and reset function of the bone plate installation and removal operation. The arc-shaped rod is fixed at the bottom of the inner cavity to provide support and guidance for the spring. The spring is sleeved on the outside and connected to the rotating plate. When the rotating plate rotates, it compresses the spring to store elastic potential energy. When the external force is removed, the spring releases the potential energy to drive the rotating plate to rotate in the opposite direction to reset, ensuring that the bone plate operation process is reversible and stable.

[0008] As a further description of the above technical solution: The limiting component includes a movable rod, the left and right sides of which are slidably connected to the inner walls of the left and right sides of the inner cavity. The rotating plate has a square opening inside, and the movable rod is slidably connected to the inner walls of the two square openings outside. Through the above technical solution, the limiting component achieves precise control of the rotation of the rotating plate. The moving rod slides between the inner walls on both sides of the cavity of the bone plate and is connected to it through the square opening inside the rotating plate. When the moving rod is driven by an external force, it can push the rotating plate to rotate around the support column, thereby realizing the connection or separation of the rotating plate and the groove of the sleeve column, ensuring the accuracy and stability of the bone plate installation and removal operation.

[0009] As a further description of the above technical solution: The bone plate body is slidably connected to multiple tie rods inside, and the bottom of each tie rod is fixedly connected to a limit frame. Through the above technical solution, this design allows doctors to control the rotation of the bone plate by pulling the lever, which in turn drives the limiting frame and the moving rod associated with the limiting frame, providing a simple and effective way to facilitate the removal of the bone plate.

[0010] As a further description of the above technical solution: The movable rod is externally fixedly connected to the inner wall of the limiting frame, and the rotating plate is internally slidably connected to the left and right sides of the outer side of the arc-shaped rod. Through the above technical solution: the rotating plate slides on the left and right sides outside the arc-shaped rod, and in conjunction with the movement of the moving rod, the moving rod pushes the rotating plate to rotate around the support column, completing the connection or separation with the groove of the sleeve column, ensuring the continuity and stability of the bone plate installation and removal.

[0011] As a further description of the above technical solution: The left side of the spring is fixedly connected to the right side of the left rotating plate, and the right side of the spring is fixedly connected to the left side of the right rotating plate. Through the above technical solution: the moving rod is fixed to the inner wall of the limiting frame. When the doctor pulls the lever to move the limiting frame, the moving rod can respond accurately and move accordingly. The rotating plate slides on both sides of the outer arc rod and rotates around the support column under the push of the moving rod, so that the rotating plate can be connected or separated from the groove of the sleeve column, ensuring that the bone plate is installed firmly and removed easily, and ensuring the continuity and reliability of the entire bone plate system operation.

[0012] As a further description of the above technical solution: The limiting frame is square in shape, and the rotating plate is L-shaped; Through the above technical solution, the shape design of the square limiting frame and the L-shaped rotating plate achieves a specific functional fit. The square limiting frame provides a stable connection structure for the moving rod, ensuring efficient and stable linear movement of the moving rod when it is pulled. The L-shaped rotating plate, on the one hand, has a unique shape that facilitates fitting with the groove of the sleeve column within a limited space to fix the bone plate; on the other hand, it is easy to connect with the moving rod through the square opening, allowing it to rotate precisely around the support column under the push of the moving rod, thus enabling convenient removal of the bone plate. The two shapes work together to ensure the reliability and smoothness of the bone plate operation.

[0013] As a further description of the above technical solution: The outer side of the rotating plate is in contact with the inner wall of the groove, and the far side of the two rotating plates is in contact with the left and right inner walls of the inner cavity.

[0014] The above technical solution achieves stable positioning of the bone plate in both fixed and ready-to-be-removed states. The outer side of the rotating plate contacts the inner wall of the groove, ensuring that the bone plate is firmly fixed to the bone and preventing displacement. The outer side of the two rotating plates contacts the inner walls of the two sides of the cavity, restricting the position of the rotating plates when the bone plate is not in use, preventing them from rotating arbitrarily, and ensuring that the bone plate functions stably in the body.

[0015] This utility model has the following beneficial effects: In this invention, firstly, pulling the lever causes the limiting frame to move, which in turn causes the moving rod to move. The movement of the moving rod causes the rotating plate to rotate around the supporting column. The force of the rotating plate's rotation compresses the spring, causing the bottom of the rotating plate to disengage from the groove. After placing the sleeve column in the designated position, releasing the lever causes the spring to rotate, allowing the bone plate to be removed. This significantly shortens the surgical time, reducing the patient's anesthesia risks and minimizing complications such as delayed awakening and respiratory depression caused by prolonged anesthesia. It also allows surgeons to complete the surgery in a more alert state, improving the precision of the surgical procedure. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 3This utility model provides an embodiment of an angled metal bone plate, including a bone plate body 1. The stability of the bone plate body 1 directly affects the bone setting effect. Multiple inner cavities 2 are formed inside the bone plate body 1. Support columns 3 are rotatably connected inside the inner cavities 2. Two rotating plates 4 are rotatably connected to the outside of the support columns 3. A telescopic component is fixedly connected to the bottom inner wall of the inner cavity 2. Multiple sleeve columns 7 are fixedly connected to the bottom of the bone plate body 1. Grooves 8 are formed on both the left and right sides inside the sleeve columns 7. When the rotating plates 4 are embedded in the grooves 8, the bone plate can be stably fixed in the corresponding position of the bone. When the rotating plates 4 disengage from the grooves 8, the bone plate can be removed. When the rotating plates 4 are in close contact with the inner wall of the grooves 8, the bone plate is firmly fixed. When the rotating plates 4 rotate and disengage from the grooves 8, the connection between the bone plate and the sleeve columns 7 is released, and a limit component is slidably connected inside the inner cavity 2. Specifically, the bone plate body 1 serves as the main body, providing a foundation for fracture fixation through its stability. Multiple internal cavities 2 accommodate components such as support columns 3 and rotating plates 4. The support columns 3 support the rotation of the rotating plates 4. When the rotating plates 4 are embedded in the grooves 8 on both sides of the sleeve column 7, the bone plate is stably fixed to the bone. Pulling the pull rod 11 in the limiting component drives the moving rod 10 to make the rotating plates 4 rotate around the support column 3 and disengage from the grooves 8, allowing the bone plate to be easily removed. The entire design takes into account both the reliability of fixation and the convenience of removal.

[0020] Reference Figures 1 to 3 The telescopic component includes an arc-shaped rod 5, the bottom of which is fixedly connected to the bottom inner wall of the inner cavity 2. A spring 6 is sleeved on the outside of the arc-shaped rod 5. The limiting component includes a moving rod 10. When the moving rod 10 is pushed by an external force, the rotating plate 4 rotates around the support column 3, changes its own position, and realizes the connection and separation with the groove 8 of the sleeve column 7. It plays a key supporting and guiding role in the installation and removal of the bone plate, ensuring the stability of the movement of the rotating plate 4. When one end of the rotating plate 4 contacts the inner wall of the groove 8, it can fix the bone plate. When pushed by the moving rod 10, it rotates around the support column 3 and disengages from the groove 8, making it easy to remove the bone plate. The left and right sides of the moving rod 10 are slidably connected to the left and right inner walls of the inner cavity 2. The inside of the rotating plate 4 is provided with a square opening 9, and the outside of the moving rod 10 is slidably connected to the inner walls of the two square openings 9. Specifically, the arc-shaped rod 5 is fixed at the bottom of the inner cavity 2 to provide support for the spring 6. The spring 6 is connected to the rotating plate 4 and stores and releases elastic potential energy when the rotating plate 4 rotates, ensuring reversible and stable action. The moving rod 10 slides on the inner walls on both sides of the inner cavity 2 and is connected to the rotating plate 4 through the square opening 9. When pushed by an external force, the moving rod 10 drives the rotating plate 4 to rotate around the support column 3, so that one end of it contacts or separates from the groove 8 of the sleeve column 7, thereby achieving stable fixation and convenient removal of the bone plate.

[0021] Reference Figures 2 to 4Multiple pull rods 11 are slidably connected inside the bone plate body 1. The telescopic assembly provides support and guidance for the spring 6. The spring 6 is sleeved on the outside of the arc-shaped rod 5, and its left and right sides are respectively connected to the rotating plate 4. When the rotating plate 4 rotates, it compresses the spring 6, and the spring 6 stores elastic potential energy. When the pull rod 11 is released, the spring 6 releases its potential energy, causing the rotating plate 4 to rotate in the opposite direction to reset, ensuring the reversibility and stability of the bone plate installation and removal operation. The pull rod 11 is slidably connected inside the bone plate body 1, and its bottom is fixedly connected to the limiting frame 12. The doctor pulls the pull rod 11 to activate the limiting assembly, indirectly controlling the rotation of the rotating plate 4. The bottom of the pull rod 11 is fixedly connected to the limiting frame 12, and the outside of the moving rod 10 is fixedly connected to the inner wall of the limiting frame 12. The moving rod 10 moves left and right. The two sides slide on the inner wall of the inner cavity 2 and are connected to the rotating plate 4 through the square opening 9, pushing the rotating plate 4 to rotate. The limiting frame 12 is square and fixed outside the moving rod 10. It is connected to the pull rod 11. Pulling the pull rod 11 drives the limiting frame 12, which in turn drives the moving rod 10, thereby controlling the rotation of the rotating plate 4 and ensuring the accuracy and stability of the operation. The inside of the rotating plate 4 is slidably connected to the left and right sides of the outside of the arc rod 5. The left side of the spring 6 is fixedly connected to the right side of the left rotating plate 4, and the right side of the spring 6 is fixedly connected to the left side of the right rotating plate 4. The limiting frame 12 is square in shape, and the rotating plate 4 is L-shaped. The outside of the rotating plate 4 is in contact with the inner wall of the groove 8, and the far side of the two rotating plates 4 is in contact with the inner walls of the left and right sides of the inner cavity 2. Specifically, the procedure achieves precise, convenient, and stable installation and removal of the bone plate. The pull rod 11 serves as the starting point of the operation; when pulled by the doctor, it drives the fixed limiting frame 12, which in turn drives the moving rod 10 connected to the limiting frame 12 to slide along the inner wall of the cavity 2. The moving rod 10 pushes the L-shaped rotating plate 4 to rotate around the support column 3 through the square opening 9. During rotation, the spring 6, which is sleeved on the arc-shaped rod 5, is compressed. The spring 6 stores elastic potential energy. When the bone plate needs to be removed, the rotating plate 4 disengages from the groove 8 of the sleeve column 7. After releasing the pull rod 11, the spring 6 releases its potential energy, causing the rotating plate 4 to rotate in the opposite direction and reset, re-contacting and fixing itself to the groove 8. The entire process is reversible, ensuring that the bone plate can both stably fix the fracture site within the body and be easily removed at the appropriate time, guaranteeing the efficiency and safety of the surgical procedure.

[0022] Working principle: During the operation of the angled metal bone plate, when the bone plate needs to be removed, the surgeon first applies a pulling force to the pull rod 11. The pulling of the pull rod 11 drives the limiting frame 12 to move synchronously, so that the moving rod 10 slides between the inner walls of the bone plate body 1 as the limiting frame 12 moves.

[0023] The rotating plate 4 is L-shaped with a square opening 9 inside. The moving rod 10 is slidably connected to the inner wall of the square opening 9 of the two rotating plates 4. Therefore, the movement of the moving rod 10 will push the rotating plate 4 to rotate around the support column 3. The support column 3 is rotatably connected in the inner cavity 2, providing a fulcrum for the rotation of the rotating plate 4. During the rotation of the rotating plate 4, pressure is applied to the springs 6 on the left and right sides of the outer side of the arc rod 5, causing the springs 6 to be compressed and deformed. As the rotating plate 4 continues to rotate, the bottom of the rotating plate 4, which was originally in contact with the groove 8 inside the sleeve column 7, gradually separates from the groove 8. At this time, the connection between the sleeve column 7 and the rotating plate 4 is released, and the connection between the bone plate body 1 and the fixation site becomes loose. Subsequently, the doctor can easily remove the sleeve column 7 from the designated fixation position.

[0024] Once the bone plate has been moved to the appropriate position for re-fixation or removal, the doctor releases the lever 11. At this time, the compressed spring 6 releases its stored elastic potential energy, generating a reaction force. This force acts on the rotating plate 4, causing it to rotate in the opposite direction under the influence of the spring 6. The rotating plate 4 returns to its initial position, and its outer surface contacts the inner wall of the groove 8 again, restoring the state when the bone plate was installed and fixed.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
