The traditional plaster fixation method is bulky, non-breathable and inconvenient to adjust. At the same time, people have higher requirements for the quality of life. Postoperative rehabilitation requires both precise reduction and fixation and the expectation of undiminished comfort. Technological development has made it possible to innovate orthoses, and advances in materials science have spawned lightweight, breathable, and high-strength materials. The combination of mechanical design and ergonomics enables it to accurately adapt to individual bone morphology, achieve personalized treatment, and meet the diverse needs of patients. Orthopedic orthoses are booming.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention rotates the rotating block by external force. When the rotating block rotates, it will drive the first screw to start rotating. When the first screw rotates, it will drive the moving blocks on both sides to move toward the middle of the first screw. At the same time, the connecting blocks on both sides also move inward together, so that the connecting blocks on both sides drive the second rotating shaft to move inward by moving inward. Then, the second rotating shaft above and below make the first rotating block and the second rotating block drive the first fixed blocks and the second fixed blocks on both sides to retract inward. When the first fixed blocks and the second fixed blocks on both sides retract inward, they will drive the resetting orthopedic plates on both sides to retract inward. When the resetting orthopedic plates on both sides are retracted, When it contracts inward, it will drive the two support rods to contract inward, and at the same time, the sliding mechanism provides sliding support for the support rods. Compared with traditional devices, this device, after the patient puts in the leg to be corrected, rotating the rotating block can drive the various components to move inward and contract collaboratively, thereby achieving positioning and clamping of the leg, allowing the splint to press tightly against the leg and firmly fixed in the leg guard. At the same time, the first screw is threadedly connected to the moving block and can be reversely locked to prevent the device from loosening and avoid accidental loosening of the fixing plate affecting normal use. It increases applicability, can better adapt to the leg conditions of different patients, provide stable support for the legs, and assist in the recovery of fractures or corrected parts.

[0015] 2. In the present invention, when the massage roller is subjected to an action force, the force will be transmitted to the placement frame. When the placement frame is subjected to an action force, the force will be transmitted to multiple springs. When the multiple springs receive the action force, they will produce elastic deformation. Then, in the gap where the action force disappears, the elastic recovery effect of the springs will drive the placement frame and massage rollers to exert a reaction force to the soles of the patient's feet. Compared with traditional devices, in this device, when the patient walks, the foot exerts force on the multiple massage rollers, which is transmitted to the springs layer by layer, causing them to produce elastic deformation. In the gap where the action force disappears, the springs recover by elastic force, driving the placement frame and massage rollers to act back on the soles of the feet, and so on. On the one hand, it can effectively buffer the vibration generated by walking, reduce the force on the legs, and avoid bone displacement due to vibration; on the other hand, the massage rollers massage the soles of the feet, promote the relaxation of the sole muscles, prevent injuries, and comprehensively guarantee the patient's walking experience and rehabilitation process.

[0016] 3. The present invention drives the second screw to start rotating by rotating the adjusting block. When the second screw rotates and the second screw is threadedly connected to the outer surface of the fixed bracket, the second screw moves downward along the thread, and at the same time drives the arc clamping block downward. Since the arc clamping block is arc-shaped, it can better fit the patient's foot and limit the range of motion of the patient's foot, thereby avoiding secondary injury caused by excessive range of motion of the patient. Compared with traditional devices, this device drives the second screw linked to it to rotate by rotating the key component adjusting block. In view of the threaded connection characteristics of the second screw and the fixed bracket, the second screw will move steadily downward along the thread, and at the same time pull the arc clamping block downward synchronously. The unique arc design of the arc clamping block is ergonomic, can closely fit the contour of the patient's foot, accurately limit the range of motion of the foot, effectively avoids the risk of secondary injury caused by excessive range of motion of the patient, and creates a stable and safe environment for bone rehabilitation.

[0025] like Figures 1 to 6 As shown, the embodiment of the present invention provides an orthopedic reduction and fixation orthosis, including a base 1, a first rectangular groove 2 is provided on the outer surface of the base 1, a sliding mechanism is slidably installed on both sides of the inner side of the first rectangular groove 2, a support rod 5 is fixedly installed on the top of the sliding mechanism, a reduction orthopedic plate 6 is fixedly installed on the inner side of the support rod 5, a first fixed block 7 is fixedly installed on the upper outer surface of the reduction orthopedic plate 6, a second fixed block 17 is fixedly installed on the lower outer surface of the reduction orthopedic plate 6, a first rotating shaft 14 is rotatably installed on the side surface of the first fixed block 7 and the side surface of the second fixed block 17, a first rotating block 8 is fixedly sleeved on the outer surface of the first rotating shaft 14 on the side surface of the first fixed block 7, and the two The first rotating block 8 is tilted downward, and the outer surface of the first rotating shaft 14 on the side of the second fixed block 17 is fixedly sleeved with the second rotating block 18, and the two second rotating blocks 18 are tilted upward, and the other ends of the first rotating block 8 and the second rotating block 18 are rotatably installed with the second rotating shaft 15, and a connecting block 9 is fixedly sleeved between the two second rotating shafts 15, and a moving block 10 is fixedly installed on the side of the connecting block 9. The internal thread of the moving block 10 is connected to the first screw rod 11, and the two ends of the first screw rod 11 pass through the interior of the two moving blocks 10, and the end of the first screw rod 11 is fixedly installed with a rotating block 12, and an elastic strap 13 is fixedly connected between the two reduction orthotic plates 6, and the elastic strap 13 is in a linear array.

[0026] When the patient puts the leg that needs correction into the base 1, the rotating block 12 is rotated by external force. When the rotating block 12 rotates, it will drive the first screw rod 11 to start rotating. When the first screw rod 11 rotates, it will drive the movable blocks 10 on both sides to move toward the middle of the first screw rod 11. At the same time, the connecting blocks 9 on both sides also move inward together, so that the connecting blocks 9 on both sides drive the second rotating shaft 15 to move inward by moving inward. Then the upper second rotating shaft 15 and the lower part make the first rotating block 8 and the second rotating block 18 drive the first fixed blocks 7 and the second fixed blocks 17 on both sides to retract inward. When the first fixed blocks 7 and the second fixed blocks 17 on both sides retract inward, it will drive the two side reduction orthopedic plates 6 to retract inward. When the two side reduction orthopedic plates 6 retract inward, it will drive the two support rods 5 to retract inward. At the same time, the sliding mechanism provides sliding support to the support rod 5, and at the same time, the elastic strap 13 fixedly connected between the two reduction orthopedic plates 6 will retract.

[0027] The rotating block 12 is rotated by external force. When the rotating block 12 rotates, the first screw rod 11 will be driven to start rotating. When the first screw rod 11 rotates, the moving blocks 10 on both sides will be driven to move toward the middle of the first screw rod 11. At the same time, the connecting blocks 9 on both sides will also move inward together, so that the connecting blocks 9 on both sides will drive the second rotating shaft 15 to move inward by moving inward. Then the second rotating shaft 15 above and the first rotating block 8 and the second rotating block 18 below will drive the first fixed blocks 7 and the second fixed blocks 17 on both sides to retract inward. When the first fixed blocks 7 and the second fixed blocks 17 on both sides retract inward, the reduction orthopedic plates 6 on both sides will be driven inward. When the reduction and correction plates 6 on both sides shrink inward, they will drive the two support rods 5 to shrink inward, and at the same time, the sliding mechanism provides sliding support for the support rods 5. Compared with traditional devices, this device, after the patient puts in the leg to be corrected, rotating the rotating block 12 can drive the various components to move inward and shrink in coordination, thereby achieving positioning and clamping of the leg, allowing the splint to press tightly against the leg and be firmly fixed in the leg guard. At the same time, the first screw 11 is threadedly connected to the moving block 10 and can be reversely locked to prevent the device from loosening, avoid accidental loosening of the fixing plate and affect normal use, increase applicability, better adapt to the leg conditions of different patients, provide stable support for the leg, and assist in the recovery of fractures or corrective parts.

[0028] Among them, a second rectangular groove 19 is opened on the upper outer surface of the base 1, and the second rectangular grooves 19 are evenly spaced and do not intersect with the first rectangular groove 2. A spring 20 is fixedly connected to the bottom inner side of the second rectangular groove 19, and the other end of the spring 20 is fixedly connected to a placement rack 21, and a massage roller 22 is fixedly installed on the outer surface of the placement rack 21.

[0029] When the patient walks, the foot will exert a downward force on the multiple massage rollers 22. When the massage rollers 22 are subjected to the force, the force will be transmitted to the placement frame 21. When the placement frame 21 is subjected to the force, the force will be transmitted to the multiple springs 20. When the multiple springs receive the force, they will produce elastic deformation. Then, in the gap where the force disappears, the elastic recovery effect of the spring 20 will drive the placement frame 21 and the massage rollers 22 to exert a reaction force on the soles of the patient's feet, and the elastic deformation of the spring 20 is within the elastic deformation range.

[0030] When the massage roller 22 is subjected to a force, the force will be transmitted to the placement frame 21. When the placement frame 21 is subjected to a force, the force will be transmitted to the multiple springs 20. When the multiple springs receive the force, they will produce elastic deformation. Then, in the gap where the force disappears, the elastic recovery effect of the springs 20 will drive the placement frame 21 and the massage rollers 22 to exert a reaction force to the patient's foot sole. Compared with traditional devices, in this device, when the patient walks, the foot exerts force on the multiple massage rollers 22, which is transmitted to the springs 20 layer by layer, causing them to produce elastic deformation. In the gap where the force disappears, the springs 20 recover by elastic force, driving the placement frame 21 and the massage rollers 22 to act in the opposite direction on the foot sole. This is repeated. On the one hand, it can effectively buffer the vibration generated by walking, reduce the force on the legs, and avoid bone displacement due to vibration; on the other hand, the massage rollers 22 massage the foot sole, promote the relaxation of the foot sole muscles, prevent injury, and comprehensively guarantee the patient's walking experience and rehabilitation process.

[0031] Among them, a fixed bracket 27 is fixedly installed on the upper outer surface of the base 1, and a second screw rod 28 is threadedly connected to the internal thread of the fixed bracket 27, and both ends of the second screw rod 28 pass through the interior of the fixed bracket 27, and an arc-shaped clamping block 29 is fixedly installed on the end of the second screw rod 28, and the arc-shaped clamping block 29 is arc-shaped, and an adjustment block 30 is fixedly installed on the other end of the second screw rod 28.

[0032] When the adjusting block 30 is rotated, the second screw rod 28 will be driven to start rotating. When the second screw rod 28 rotates, and because the second screw rod 28 is in contact with the outer surface of the fixing bracket 27 and is threadedly connected, the second screw rod 28 moves downward along the thread, and at the same time drives the arc-shaped clamping block 29 to move downward. Since the arc-shaped clamping block 29 is arc-shaped, it can better fit the patient's foot.

[0033] By rotating the adjusting block 30, the second screw rod 28 will be driven to start rotating. When the second screw rod 28 rotates and because the second screw rod 28 is threadedly connected to the outer surface of the fixed bracket 27, the second screw rod 28 moves downward along the thread, and at the same time drives the arc clamping block 29 to move downward. Since the arc clamping block 29 is arc-shaped, it can better fit the patient's foot and limit the range of motion of the patient's foot, thereby avoiding secondary injury caused by excessive range of motion of the patient. Compared with traditional devices, this device drives the second screw rod 28 linked to it to rotate by rotating the key component adjusting block 30. Given the threaded connection characteristics of the second screw rod 28 and the fixed bracket 27, the second screw rod 28 will move steadily downward along the thread, while pulling the arc clamping block 29 downward synchronously. The unique arc design of the arc clamping block 29 is ergonomic and can closely fit the contour of the patient's foot, accurately limit the range of motion of the foot, effectively avoiding the risk of secondary injury caused by excessive range of motion of the patient, and creating a stable and safe environment for bone rehabilitation.

[0034] The sliding mechanism includes a slider 4 slidably mounted on the inner side of the first rectangular groove 2 , with sliding grooves 3 provided on both sides of the first rectangular groove 2 and extension blocks on both sides of the slider 4 extending to the inner side of the sliding groove 3 .

[0035] By extending the extension blocks on both sides of the slider 4 to the inner side of the slide groove 3, the slider 4 can be effectively limited when sliding, avoiding the slider 4 from derailing due to excessive force.

[0036] The second flexible pad 31 is fixedly mounted on the inner side of the reduction and correction plate 6 , and the second flexible pad 31 is arc-shaped and fits the inner wall of the reduction and correction plate 6 .

[0037] The arc-shaped second flexible pad 31 fits against the inner wall of the reduction and correction plate 6 , so that the reduction and correction plate 6 can be more comfortable when it fits the part of the patient that needs correction.

[0038] Among them, the upper outer surface of the base 1 is provided with air holes 26, and the air holes 26 are in a linear array and evenly spaced from the second rectangular groove 19. The left side of the base 1 is provided with an air inlet hole 25, and the air inlet hole 25 is connected to the air blowing hole 26.

[0039] The air inlet 25 is connected to the air blowing hole 26, so that the foot has good ventilation and heat dissipation performance, can quickly dissipate heat and moisture from the soles of the feet, prevent odor and excessive sweating on the soles of the feet, and greatly improve comfort.

[0040] A fixing plate 23 is fixedly mounted on the inner side of the support rod 5 , a first flexible pad 24 is fixedly mounted on the inner wall of the fixing plate 23 , and the fixing plate 23 does not intersect with the massage roller 22 .

[0041] When the support rod 5 contracts inward, the fixing plate 23 will be driven to contract inward together, thereby limiting the two sides of the foot, and at the same time, the first flexible pads 24 on both sides can flexibly wrap the feet on both sides.

[0042] A limit block 16 is fixedly mounted on the other end of the first screw rod 11 , and a radius of the limit block 16 is greater than a radius of the first screw rod 11 .

[0043] Since the radius of the limiting block 16 is larger than the radius of the first screw rod 11 , the bottom moving block 10 can be limited to avoid the bottom moving block 10 being separated from the first screw rod 11 .

[0044] Working principle and usage process:

[0045] When the patient puts the leg that needs correction into the base 1, the rotating block 12 is rotated by external force. When the rotating block 12 rotates, it will drive the first screw rod 11 to start rotating. When the first screw rod 11 rotates, it will drive the movable blocks 10 on both sides to move toward the middle of the first screw rod 11. At the same time, the connecting blocks 9 on both sides also move inward together, so that the connecting blocks 9 on both sides drive the second rotating shaft 15 to move inward by moving inward. Then the upper second rotating shaft 15 and the lower part make the first rotating block 8 and the second rotating block 18 drive the first fixed blocks 7 and the second fixed blocks 17 on both sides to retract inward. When the first fixed blocks 7 and the second fixed blocks 17 on both sides retract inward, it will drive the two side reduction orthopedic plates 6 to retract inward. When the two side reduction orthopedic plates 6 retract inward, it will drive the two support rods 5 to retract inward. At the same time, the sliding mechanism provides sliding support to the support rod 5, and at the same time, the elastic strap 13 fixedly connected between the two reduction orthopedic plates 6 will retract.

[0046] When the patient walks, the foot will exert a downward force on the multiple massage rollers 22. When the massage rollers 22 are subjected to the force, the force will be transmitted to the placement frame 21. When the placement frame 21 is subjected to the force, the force will be transmitted to the multiple springs 20. When the multiple springs receive the force, they will produce elastic deformation. Then, in the gap where the force disappears, the elastic recovery effect of the spring 20 will drive the placement frame 21 and the massage rollers 22 to exert a reaction force on the soles of the patient's feet, and the elastic deformation of the spring 20 is within the elastic deformation range.

[0047] When the adjusting block 30 is rotated, the second screw rod 28 will be driven to start rotating. When the second screw rod 28 rotates, and because the second screw rod 28 is in contact with the outer surface of the fixing bracket 27 and is threadedly connected, the second screw rod 28 moves downward along the thread, and at the same time drives the arc-shaped clamping block 29 to move downward. Since the arc-shaped clamping block 29 is arc-shaped, it can better fit the patient's foot.
