Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an orthopedic bone plate. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system and uses drugs, surgery and physical methods to maintain and develop the normal shape and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries and diseases has changed significantly.

[0003] Bone plate fixation surgery is an important method for fracture treatment. However, current bone plates are all straight strips at one end, which have poor stability during use and are prone to slippage and displacement. Furthermore, the edge of the straight strip bone plate will constantly press on the patient's arm or thigh, causing discomfort and the patient's desire to remove the bone plate. In addition, bone plates cannot be changed or adjusted according to different patients' body sizes, making the adjustment and installation process cumbersome and reducing the work efficiency of staff using bone plates. Therefore, there is a need for a bone plate specifically designed for orthopedic use. Summary of the Invention

[0004] The purpose of this invention is to provide an orthopedic bone plate to solve the problems mentioned in the background art, such as poor stability, easy slippage and displacement, the edge of the straight bone plate constantly pressing on the patient's arm or thigh, which causes the patient to feel uncomfortable and want to remove the bone plate, and the inability to replace or adjust the bone plate according to the different body sizes of different patients.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an orthopedic bone plate, comprising a fixation plate, wherein arc-shaped plates are respectively provided on both sides of the fixation plate, a snap-fit ​​bracket is fixedly installed on the outer wall of the arc-shaped plate, and the arc-shaped plate is snapped into the fixation plate through the snap-fit ​​bracket, an insertion groove is provided on the inner wall of the arc-shaped plate, a T-shaped post is inserted into the arc-shaped plate through the insertion groove, a threaded groove is provided on one inner wall of the T-shaped post, a strip-shaped groove is provided on one outer wall of the fixation plate, a fixing screw is inserted into the fixation plate through the strip-shaped groove, and the fixing screw is threadedly connected to the T-shaped post through the threaded groove;

[0006] Positioning components are respectively fitted on the side walls of the fixing plate. A first fixing strap and a second fixing strap are respectively installed on the two outer walls of the positioning components, and the first fixing strap and the second fixing strap are opposite to each other. A Velcro closure is installed on one outer wall of the first fixing strap, and a Velcro closure matching the Velcro closure is installed on one outer wall of the second fixing strap. The fixing plate and the arc plate are fixed to the human body by the first fixing strap and the second fixing strap, and the Velcro closure and the Velcro closure. An installation groove is opened on one outer wall of the fixing plate. Limiting posts are respectively installed on one outer wall of the fixing plate, and the limiting posts are located inside the installation groove. The positioning components are engaged and fixed to the fixing plate by the limiting posts.

[0007] The curved plate is inserted into the fixed plate using a clip-on bracket. Then, the T-shaped post is manually inserted into the insertion slot on the curved plate. Next, one end of the fixing screw is manually inserted into the strip groove 6 and threaded to the T-shaped post through the threaded groove, thus facilitating the fixing and limiting of the curved plate. Then, the positioning component, the first fixing band, and the second fixing band inserted into the fixed plate are manually moved to the appropriate position, and then fixed and limited with the cooperation of the limiting post. Finally, the Velcro on the second fixing band and the Velcro on the first fixing band are pasted together, thus firmly connecting the two sets of fixed plates to the curved plate.

[0008] Preferably, limit blocks are installed on one side wall of the arc-shaped plate, and the limit blocks are located inside the insertion groove. Limit grooves are opened on the outer wall of the T-shaped column, and the T-shaped column is engaged with the limit block and the arc-shaped plate through the limit groove.

[0009] By using the limiting block and limiting groove, it is possible to prevent the fixing screw from causing the T-shaped column to rotate together when the fixing screw is threadedly connected to the T-shaped column, thereby avoiding affecting the fixing effect of the arc plate.

[0010] Preferably, the positioning component includes a mounting frame, which is located outside the fixing plate. The first fixing strap and the second fixing strap are located on the outer walls of the two sides of the mounting frame, respectively. An L-shaped rod is movably inserted into the mounting frame, and a spring is sleeved on the side wall of the L-shaped rod. The L-shaped rod engages with the limiting post.

[0011] By manually pressing the L-shaped rod, it is moved away from the limiting post, which facilitates the adjustment of the position of the mounting frame. Then, the L-shaped rod is released, allowing it to reset under the action of the spring and engage with the limiting post, thus facilitating the positioning of the mounting frame.

[0012] Preferably, a pressing post is installed at the end of the L-shaped rod away from the fixing plate, and the diameter of the pressing post is larger than that of the L-shaped rod, and the spring is located between the mounting frame and the pressing post.

[0013] By pressing the column, one end of the spring is made to have a force point, thereby ensuring that the spring can drive the L-shaped rod to return to its original position.

[0014] Preferably, one end of the arc-shaped plate is provided with a positioning groove, and the end of the arc-shaped plate away from the positioning groove is provided with a positioning strip, and the positioning strip is inserted into the positioning groove.

[0015] The positioning groove and positioning strip are engaged to avoid deviation between the two sets of fixed plates and the curved plate.

[0016] Preferably, a rubber pad is installed on the inner wall of the arc-shaped plate, and a round hole is opened on one side wall of the rubber pad. One end of the T-shaped column passes through the round hole and is inserted into the insertion slot and the arc-shaped plate respectively.

[0017] The use of rubber pads helps improve patient comfort.

[0018] Preferably, through holes are provided on one side wall of the arc-shaped plate and the rubber pad, and the through holes are strip-shaped.

[0019] The strip-shaped perforations prevent the skin inside the curved plate from getting too hot due to ventilation issues.

[0020] The technical effects and advantages of this invention are as follows:

[0021] By incorporating an arc-shaped plate, insertion slots, T-shaped posts, strip grooves, and fixing screws, the distance of the arc-shaped plate can be adjusted according to the patient's condition. This also improves the stability of the fixation plate and its protection of the bone, preventing slippage, displacement, or pressure on the patient's skin. Consequently, it enhances patient comfort and facilitates rehabilitation.

[0022] The installation frame, first fixing strap, second fixing strap, Velcro, Velcro tabs, positioning groove and positioning strip make it easy for medical staff to fix the two fixing plates and the curved plate. This not only makes it easier for medical staff to disassemble the fixing plates later, but also reduces the difficulty of installing the bone plate.

[0023] The L-shaped rod, spring, mounting groove, and limiting post make it easy for medical staff to adjust and fix the distance between the two mounting frames. This reduces the difficulty of fixing the fixing plate and the arc plate and improves the fixing effect and practicality of the device. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides, for example Figure 1-6The orthopedic bone plate shown includes a fixation plate 1, with arc-shaped plates 2 on both sides of the fixation plate 1. A snap-fit ​​bracket 3 is fixedly installed on the outer wall of the arc-shaped plate 2, and the arc-shaped plate 2 is snapped into the fixation plate 1 via the snap-fit ​​bracket 3. The snap-fit ​​bracket 3 facilitates the snapping of the arc-shaped plate 2 and the fixation plate 1, thereby improving the stability of the fixation plate 1 and its protection of the bone, while also preventing the edges of the fixation plate 1 from pressing against the patient's skin, thus improving patient comfort. An insertion groove 4 is formed on the inner wall of the arc-shaped plate 2, through which a T-shaped post 5 is inserted. A threaded groove is formed on one inner wall of the T-shaped post 5, and a strip groove 6 is formed on one outer wall of the fixation plate 1. The strip groove 6 ensures that one end of a post 7 can pass through posts 1 and 5 and the threaded groove for threaded connection. This helps to avoid affecting the fixed limit of 2. The fixing plate 1 is connected to the fixing screw 7 through the strip groove 6, and the fixing screw 7 is threaded to the T-shaped column 5 through the threaded groove. The T-shaped column 5 is manually inserted into the insertion groove 4, and then the fixing screw 7 is manually inserted into the strip groove 6 on the fixing plate 1 and threaded to the threaded groove on the T-shaped column 5. This helps to fix the arc plate 2 on the fixing plate 1 and prevent the arc plate 2 from slipping or displacing during use. A rubber pad is installed on the inner wall of the arc plate 2. A round hole is opened on one side wall of the rubber pad, and one end of the T-shaped column 5 passes through the round hole and is inserted into the insertion groove 4 and the arc plate 2 respectively. The rubber pad not only improves the patient's comfort, but also has the anti-corrosion effect of the device.

[0033] Positioning components 8 are respectively fitted onto the side walls of the fixing plate 1. A first fixing strap 9 and a second fixing strap 10 are respectively installed on the outer walls of the two sides of the positioning components 8, with the first fixing strap 9 and the second fixing strap 10 facing each other. A Velcro 11 is installed on one outer wall of the first fixing strap 9, and a Velcro 12 matching the Velcro 11 is installed on one outer wall of the second fixing strap 10. The fixing plate 1 and the curved plate 2 are fixed to the human body by the first fixing strap 9 and the second fixing strap 10, using the Velcro 11 and the Velcro 12. The Velcro 12 on the second fixing strap 10 is then attached to the Velcro 11 on the first fixing strap 9. This securely connects the two sets of fixing plates 1 and the arc-shaped plate 2. An installation groove 13 is provided on one outer wall of the fixing plate 1, and a limiting post 14 is installed on one outer wall of the fixing plate 1. The limiting post 14 is located inside the installation groove 13, and the positioning component 8 is fixed to the fixing plate 1 by the limiting post 14. The positioning component 8 cooperates with the limiting post 14 installed on the fixing plate 1 to fix and limit the first fixing strap 9 and the second fixing strap 10 after the distance position is adjusted, so that the Velcro 11 and Velcro 12 can stably fix the adjusted fixing plate 1 and arc-shaped plate 2 to the human body.

[0034] In this embodiment, limit blocks 18 are installed on one side wall of the arc plate 2, and the limit blocks 18 are located inside the insertion groove 4. Limit grooves 19 are opened on the outer wall of the T-shaped column 5, and the T-shaped column 5 is engaged with the limit blocks 18 and the arc plate 2 through the limit grooves 19. When the T-shaped column 5 is inserted into the insertion groove 4, the limit blocks 18 on the arc plate 2 are also engaged with the limit grooves 19 on the T-shaped column 5. This facilitates the limiting of the T-shaped column 5 inserted into the insertion groove 4, thereby preventing the fixing screw 7 from rotating together with the T-shaped column 5 when it is threaded into the insertion groove 4. This helps to avoid affecting the fixing effect between the arc plate 2, the clamping frame 3 and the fixing plate 1, and prevents the arc plate 2 and the clamping frame 3 from loosening and slipping during use due to unstable fixing, thus preventing the impact on the patient's rehabilitation.

[0035] In this embodiment, the positioning component 8 includes a mounting frame 81, which is located outside the fixing plate 1. The first fixing strap 9 and the second fixing strap 10 are respectively located on the outer walls of the two sides of the mounting frame 81. An L-shaped rod 82 is movably inserted into the mounting frame 81. A spring 83 is sleeved on the side wall of the L-shaped rod 82, and the L-shaped rod 82 meshes with the limiting post 14. A pressing post is installed at the end of the L-shaped rod 82 away from the fixing plate 1, and the diameter of the pressing post is larger than that of the L-shaped rod 82. The spring 83 is located between the mounting frame 81 and the pressing post. The positioning component 8 is positioned by manually pressing the L-shaped rod 82 to one side. The pressing column is used to move the L-shaped rod 82 away from the limiting column 14, thereby facilitating the adjustment of the positions of the mounting frame 81, the first fixing band 9, and the second fixing band 10. Then, the pressing column is released, so that the L-shaped rod 82 and the pressing column are reset under the action of the spring 83 and engage with the limiting column 14, thereby facilitating the fixing and limiting of the adjusted mounting frame 81, the first fixing band 9, and the second fixing band 10. This reduces the installation difficulty of the fixing plate 1 and the arc plate 2 and enables the fixing plate 1 and the arc plate 2 to be fixed after adjustment.

[0036] In this embodiment, a positioning groove 15 is provided at one end of the arc plate 2, and a positioning strip 16 is installed at the end of the arc plate 2 away from the positioning groove 15. The positioning strip 16 is inserted into the positioning groove 15. By engaging the positioning groove 15 and the positioning strip 16, the two sets of fixing plates 1 and arc plate 2 can be stably and parallelly fixed at the joint. This helps to avoid deviation between the two sets of fixing plates 1 and arc plate 2, thereby avoiding any impact on the fixation of the fixing plates 1 and arc plate 2 and the protection of the joint.

[0037] In this embodiment, through holes 17 are respectively provided on one side wall of the arc plate 2 and the rubber pad, and the through holes 17 are strip-shaped. The strip-shaped through holes 17 facilitate the breathability of the device, thereby preventing the skin in the arc plate 2 from getting hot due to breathability issues, and thus preventing any impact on the patient's comfort.

[0038] Working principle of the invention: The present invention is an orthopedic bone plate. In use, the arc plate 2 is first inserted into the fixation plate 1 through the snap-fit ​​bracket 3, and the distance between the two arc plates 2 is adjusted. After the adjustment is appropriate, the T-shaped post 5 is inserted into the insertion groove 4 and the limiting block 18 is snapped into the limiting groove 19. Then, the doctor inserts the fixing screw 7 into the strip groove 6 and threadedly connects it with the T-shaped post 5, thereby facilitating the fixation of the arc plate 2 after the distance is adjusted. Then, the two sets of fixation plates 1 and arc plates 2 are wrapped around the patient's joint bone, and the positioning strip 16 on the arc plate 2 is snapped into and aligned with the positioning groove 15, thereby avoiding deviation between the two sets of fixation plates 1 and arc plates 2. Then, the Velcro 12 on the second fixation strap 10 is pasted with the Velcro 11 on the first fixation strap 9, thereby firmly connecting the two sets of fixation plates 1 and arc plates 2.

[0039] By manually pressing the pressing column, the L-shaped rod 82 is moved away from the limiting column 14, which facilitates the adjustment of the position of the mounting frame 81, the first fixing strap 9, and the second fixing strap 10. Then, the pressing column is released, so that the L-shaped rod 82 and the pressing column are reset under the action of the spring 83 and engage with the limiting column 14. This facilitates the fixing and limiting of the adjusted mounting frame 81, the first fixing strap 9, and the second fixing strap 10, so that the Velcro 11 and the Velcro 12 can stably fix the adjusted fixing plate 1 and the arc plate 2 to the human body. This reduces the installation difficulty of the fixing plate 1 and the arc plate 2 and is beneficial to the patient's rehabilitation treatment.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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.
