Description

Technical Field

[0001] The present invention relates to the field of medical devices, in particular to a fracture correction and fixation device. Background Art

[0002] Orthoses are biomedical rehabilitation devices used to prevent or correct bone or joint deformities. They can also relieve pain, improve function, and support body structure. Orthoses can be used anywhere on the body, from the limbs to the spine, and their design and function vary depending on their intended use and location.

[0003] Among them, plaster orthosis is a traditional fixed orthosis that prevents further displacement of the fracture site by fixing the limb in a specific position, providing a stable environment for fracture healing. However, this traditional plaster orthosis has many disadvantages. Plaster orthosis is not breathable and can easily cause skin redness, swelling, itching, and other phenomena. During long-term use, the patient's skin may develop eczema, dermatitis and other skin problems due to the inability to sweat. Plaster orthosis is relatively bulky and large in size, which will bring inconvenience to the patient's life. For example, when wearing a plaster orthosis, the patient's movement is restricted and inconvenient, and it may even affect daily dressing and self-care. Once the plaster orthosis is fixed, it is difficult to adjust. If the patient's limb swells or other conditions require adjustment of the fixed position or tightness, the plaster orthosis may need to be remade. In addition, plaster orthosis is not convenient for X-ray examination, making it difficult to observe the healing of the fracture.

[0004] Therefore, a fracture correction fixation device is proposed to address the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Reference Figures 1-4A fracture orthopedic fixation device includes two fixing plates 1, each fixing plate 1 is provided with a breathable window 2, and the window 2 is opened along the length direction of the fixing plate 1, each window 2 is provided with a plurality of orthopedic components 3, and each orthopedic component 3 includes an arc-shaped extrusion plate 4, the extrusion plate 4 is placed on the inner side of the fixing plate 1, and each extrusion plate 4 is provided with a protrusion 5, the protrusion 5 is placed in the window 2, and protrudes from the outer surface of the fixing plate 1; In the embodiment of the present invention, the fracture orthopedic fixation device is mainly suitable for patients with arm or leg fractures and is used to clamp a relatively flat fracture site. The specific operation is as follows: first, the orthopedic component 3 is placed at the fracture point, specifically on both sides and above and below the fracture point, that is, the compression plate 4 is placed on both sides and above and below the fracture point, and then the fixing plate 1 is assembled, and the protrusion 5 passes through the window 2, as shown in FIG. Figure 1 and Figure 2 As shown, the rod between two adjacent fixing plates 1 is used to simulate an arm or a leg; Then, medical gauze is wrapped around the two fixing plates 1, for example, by wrapping the two fixing plates 1 around the arm, and the fixing plates 1 squeeze the squeezing plates 4, which are clamped on both sides of the fracture point and above and below to prevent further displacement of the fracture site and provide a stable environment for fracture healing; The fixing plate 1 can be made of gypsum material, and the window 2 opened on the fixing plate 1 can reduce the total weight of the fixing plate 1, making it lighter and reducing the impact on the patient's life. At the same time, the opening of the window 2 is conducive to air circulation, so that more air can come into contact with the skin, reducing the inability to discharge sweat and causing skin problems such as eczema and dermatitis. At the same time, the orthopedic component 3 is detachably assembled on the fixing plate 1. When the limb swells or other situations require adjustment of the fixed position or tightness, the position of the orthopedic component 3 is adjusted, or the orthopedic component 3 with different thickness of the extrusion plate 4 is replaced, so that the fracture orthopedic fixation device is more comfortable to wear and helps to accelerate the healing of the fracture.

[0022] Reference Figures 1-6 Each of the extrusion plates 4 is made of rubber material, and the interior of each extrusion plate 4 is hollow, the interior of the extrusion plate 4 is connected to the hollow raised portion 5 thereon, and an air injection nozzle 6 is provided on one side of the raised portion 5; When a limb is swollen or other situations require adjustment of the fixed position or tightness, the medical gauze is removed for adjustment. The entire removal and rewinding process is relatively cumbersome. For this purpose, an expandable and retractable extrusion plate 4 is designed. In this embodiment, the extrusion plate 4 is made of medical rubber material, and its interior is hollow. When the extrusion plate 4 is not in use, it is flat. When it is placed on the fracture site, a certain amount of air is injected into the extrusion plate 4, and the extrusion plate 4 expands to different degrees to squeeze and correct the fracture site. Specifically, an external The boundary air pump is connected to the external air pump with a hose, the end of the hose is inserted into the air injection nozzle 6, and a one-way valve is set in the air injection nozzle 6. When the air injection nozzle 6 is not connected to the hose, the gas in the protrusion 5 and the extrusion plate 4 cannot be discharged by itself. When the hose is connected to the air injection nozzle 6, the entry or discharge of gas can be controlled by the external air pump, thereby controlling the expansion degree of the extrusion plate 4, and then controlling the tightness of the two fixed plates 1 wrapped around the arm, providing patients with a comfortable wearing environment. Compared with the method of removing and then wrapping medical gauze, the operation is more flexible and the tightness adjustment is more convenient.

[0023] Reference Figure 5-Figure 6 , each of the protrusions 5 has a groove 7 on its outer surface, and a plurality of slots 8 perpendicular to the groove 7. An elastic tensioning band 27 is provided in the groove 7. The tensioning band 27 wraps the outer surface of the fixing plate 1. A card plate 9 is embedded in the slot 8. The card plate 9 is used to squeeze and fix the end of the tensioning band 27 in the slot 8; The fixing plate 1 can be fixed to the arm by medical gauze, and each orthotic component 3 can be fixed to the fixing plate 1 by an elastic tensioning band 27. Specifically, the tensioning band 27 is wrapped around the fixing plate 1 and embedded in the groove 7 on the raised portion 5. The positions of the two ends of the tensioning band 27 are adjusted so that the overlapping parts of the two ends are placed in the groove 7. Then, the overlapping parts of the tensioning band 27 are squeezed and embedded in the clamping groove 8 by the clamping plate 9. At this time, the tensioning band 27 can be fixed to the orthotic component 3. Except for the overlapping parts, the tensioning band 27 is attached and squeezed together with the fixed outer surface to fix the position of the orthotic component 3. That is, when the squeezing plate 4 in the orthotic component 3 expands to a small extent, the orthotic component 3 may be displaced between the arm and the fixing plate 1. After the orthotic component 3 is fixed to the fixing plate 1 by the tensioning band 27, the orthotic component 3 can be constrained and its position can be stabilized, so that the orthotic component 3 can be stably and accurately opposite to the fracture site, providing a stable environment for fracture healing.

[0024] Reference Figures 1-4 ,as well as Figure 7 The outer surface of the fixing plate 1 is provided with a plurality of fastening belts 10, each fastening belt 10 includes a hook 11 symmetrically arranged on both sides of one end, an elastic portion 12 in the middle and a plurality of hanging rods 13 arranged on both sides of the other end; The fastening belt 10 wraps and fastens the two fixing plates 1, the hook 11 is hooked on the hanging rod 13, and the outer surface of the fixing plate 1 is pressed on the hook 11; In this embodiment, the fastening belt 10 is designed to replace the medical gauze. When using the medical gauze, multiple turns are required. Similarly, when adjusting the position of the orthopedic component 3 at a certain position on the arm, the entire medical gauze needs to be removed to adjust the position of the orthopedic component 3. In this embodiment, the fastening belt 10 is used, and the position of the orthopedic component 3 can be adjusted by removing only one or more fastening belts 10. Specifically, the fastening belt 10 wraps and fastens the two fixing plates 1, pulls the hook 11 at one end of the fastening belt 10, and hangs it on the hanging rod 13 at the other end of the fastening belt 10. After hanging, the outer surface of the fixing plate 1 squeezes the hook 11 outward, so that the hook 11 can be further firmly hung on the hanging rod 13. At the same time, multiple hanging rods 13 are provided. According to the required tightness of the clamping end of the fixing plate 1 on the arm, the hanging rods 13 in different positions are selected for hanging; when the position of the orthopedic component 3 needs to be adjusted, the hook 11 is removed from the hanging rod 13, the fastening belt 10 close to the orthopedic component 3 is loosened, and then the position of the orthopedic component 3 is adjusted horizontally. After the adjustment is completed, the fastening belt 10 is installed on the fixing plate 1.

[0025] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 7 , an arc-shaped hanging plate 14 is provided at the other end of each of the fastening belts 10 , the edge of the hanging plate 14 extends into the fixed plate 1 , and the curved portion of the hanging plate 14 is hung on the edge of the fixed plate 1 ; The hanging plate 14 is first used to position the fastening belt 10, such as Figure 2 and Figure 3 As shown, the hanging plate 14 is hung on the edge of one of the fixing plates 1, and the position of the other end of the fastening belt 10 can be fixed. At this time, it is necessary to press and support the other end of the fastening belt 10, free up your hand, grab the fixing plate 1, and pull one end of the fastening belt 10, and hang the hook 11 on it on the hanging rod 13, which is convenient for medical personnel to operate the fracture orthopedic fixation device, and then use it to stably squeeze the hook 11. The hanging plate 14 is hung on the edge of one of the fixing plates 1 to determine the position of the hanging rod 13 at the other end of the fastening belt 10. When the subsequent hook 11 is hung on the hanging rod 13, the hook 11 can be stably squeezed by the outer surface of the fixing plate 1, thereby stably hanging the hook 11 on the hanging rod 13.

[0026] Reference Figures 8-10Each of the fixing plates 1 includes end plates 15 provided at both ends thereof, and a plurality of intermediate plates 16 provided between the two end plates 15. Adjacent intermediate plates 16, as well as the intermediate plates 16 and the end plates 15 are fixed together by connecting components, and each connecting component includes two screws 17. One end of each screw 17 is threadedly connected to a fixing hole 18 opened on the end surface of the intermediate plate 16, and the other end of each screw 17 is rotatably connected together; In the embodiment of the present invention, the designed fixing plate 1 can also be made of a relatively lightweight plastic plate, and the fixing plate 1 is divided into multiple pieces, specifically divided into end plates 15 at the ends and multiple intermediate plates 16 in the middle. Different numbers of fixing plates 1 are selected according to the length of the arm or leg. Specifically, two adjacent intermediate plates 16 are fixed together by a connecting component. According to the length of the arm or leg and the fracture area, the number of intermediate plates 16 used is increased or decreased. The end of the screw 17 is threadedly connected to the fixing hole 18 on the end face of the intermediate plate 16, or the fixing hole 18 on the end face of the end plate 15, to connect the adjacent intermediate plates 16 together, and to connect the end plate 15 with the intermediate plate 16 together, so as to flexibly adapt to various and complex situations. At the same time, a turntable 19 is provided at the other end of the two screw rods 17. The two turntables 19 overlap with each other and are connected by a fastening bolt 20. The angle between the axes of the two adjacent screw rods 17 can be adjusted, thereby adjusting the inclination angle of the two adjacent intermediate plates 16 and the inclination angle between the intermediate plate 16 and the end plate 15 to adapt to the position of the arm or leg joint and free up space for movement.

[0027] Reference Figures 8-10 Each of the fixing holes 18 is arranged in an arc shape, and the interior of the fixing hole 18 is arranged in a flared shape; an anti-slip plate 21 is fixed to the end of each of the screw rods 17, and a fastening nut 22 is threadedly connected to each of the screw rods 17; Insert the anti-slip plate 21 along the arc-shaped fixing hole 18, and rotate the screw 17 so that the anti-slip plate 21 is stuck in the flared part of the fixing hole 18, and then rotate the fastening nut 22 to fasten the screw 17 to the middle plate 16; and the arc-shaped fixing hole 18, the screw 17 can be displaced along the fixing hole 18 to achieve the purpose of staggering the two adjacent middle plates 16 relative to each other, and the flexible adjustment degree is increased again, and the applicability is stronger.

[0028] Reference Figures 8-10 The outer edge of each end plate 15 is rolled outward, and the edge of the rolled portion of the end plate 15 is covered with a silicone cushion; The outer edge of the end plate 15 is rolled outward to free up space for elbow or leg joint movement. A silicone cushion is placed on the rolled portion to reduce scratching of the skin surface and compression of body tissues, improving comfort. Furthermore, the silicone material has excellent biocompatibility and does not cause skin allergies or irritation. This property can effectively reduce allergic reactions such as itching and redness, protecting skin health, and is highly necessary for fracture areas that cannot come into contact with water.

[0029] Reference Figure 5 and Figure 6 , a support plate 23 is provided on both sides of each protrusion 5, and the support plate 23 is lifted to insert the card plate 9 into the card slot 8; The support plate 23 is provided for pulling the orthopedic component 3. When the card plate 9 is embedded in the card slot 8, a pressing force needs to be applied to the protrusion 5, which will compress the fracture site. For this reason, a support plate 23 is provided on the protrusion 5. The support plate 23 is lifted up, and the card plate 9 together with the tensioning belt 27 are forcefully embedded in the card slot 8. At this time, the extrusion force applied to the fracture site is offset by lifting the support plate 23, thereby protecting the fracture site and avoiding secondary injury.

[0030] Reference Figure 8 and Figure 10 , each of the fixing plates 1 has an inserting hole 24 at its end, an elastic band 25 is provided in the inserting hole 24, and one end of the elastic band 25 has a through hole 26 for hooking the hand; For the fracture site on the arm, the through hole 26 on one end of the elastic band 25 is sleeved on the patient's finger, and the other end of the elastic band 25 passes through the insertion hole 24 and is inserted into the fixing hole 18 on it through the insertion pin to fix it on the fixing plate 1. The position of the entire fracture orthopedic fixation device on the arm can be constrained by the fingers. The palm and wrist will hinder the fracture orthopedic fixation device from moving toward the palm, but the fracture orthopedic fixation device moves toward the elbow. The elastic band 25 and the fingers can cooperate to stabilize the fracture orthopedic fixation device to prevent the fracture orthopedic fixation device from being displaced on the arm.

[0031] Working principle: First, the orthosis component 3 is placed at the fracture point, specifically on both sides and above and below the fracture point, that is, the compression plates 4 are placed on both sides and above and below the fracture point, and then the fixation plate 1 is assembled, with the protrusion 5 passing through the window 2. Then, medical gauze is wrapped around the two fixation plates 1, for example, by wrapping the medical gauze around the arm and fixing them. The fixation plate 1 squeezes the compression plates 4, which are clamped on both sides and above and below the fracture point to prevent further displacement of the fracture site and provide a stable environment for fracture healing; The fixing plate 1 can be made of gypsum material, and the window 2 opened on the fixing plate 1 can reduce the total weight of the fixing plate 1, making it lighter and reducing the impact on the patient's life. At the same time, the opening of the window 2 is conducive to air circulation, so that more air can come into contact with the skin, reducing the inability to discharge sweat and causing skin problems such as eczema and dermatitis. At the same time, the orthopedic component 3 is detachably assembled on the fixing plate 1. When the limb swells or other situations require adjustment of the fixed position or tightness, the position of the orthopedic component 3 is adjusted, or the orthopedic component 3 with different thickness of the extrusion plate 4 is replaced, so that the fracture orthopedic fixation device is more comfortable to wear and helps to accelerate the healing of the fracture.
