Description

Technical Field

[0001] This invention relates to the field of medical training equipment technology, and in particular to an orthopedic spinal correction device. Background Technology

[0002] Scoliosis, kyphosis and other spinal deformities are relatively common in modern society, seriously affecting patients' physical health and quality of life. According to relevant medical statistics, the incidence of spinal deformities in certain age groups is on the rise. For such conditions, orthopedic spinal correction devices are often needed for treatment and rehabilitation.

[0003] While existing orthopedic spinal correction devices can provide correction to some extent, they still have many shortcomings. Some traditional correction devices have a relatively simple structural design, making it difficult to accurately adapt to the complex and diverse spinal physiological characteristics of different patients. This results in poor correction effects and makes it difficult to achieve personalized and dynamic precision treatment. For example, the correction device is a one-piece structure. The patient lies on the correction device, with the patient's spine resting on the curved surface of the correction device. However, the curvature cannot be changed, and it cannot adapt to different degrees of spinal curvature (lying completely on it may cause discomfort or even pain if the spinal curvature is slightly severe). It is also impossible to adjust the correction force and method in real time according to the patient's treatment progress, making it difficult to achieve personalized precision treatment.

[0037] Reference Figures 1-11This invention proposes an orthopedic spinal correction device, including a base plate 1 on which an arc-shaped correction frame is mounted. The arc-shaped correction frame includes multiple correction plates 2 and an adjustment mechanism. The multiple correction plates 2 can form an arc-shaped correction surface. Soft padding is laid on the correction plates 2, and the edges are chamfered. The adjustment mechanism can adjust the curvature of the arc-shaped correction surface and also adjust the tilt angle of the correction plates 2. In reality, patients' spinal curvature varies. If patients with different degrees of spinal curvature use a correction device of the same curvature for correction, the discomfort experienced during correction will also vary. The effects will vary, especially for patients with significant curvature. Abrupt correction could potentially injure the spine. Therefore, the adjustment mechanism adjusts the curvature of the arc-shaped correction surface according to the patient's spinal curvature, adapting to different patients and allowing for gradual correction. Additionally, some patients may have scoliosis. Therefore, the following design is implemented: two limiting side plates 3 are slidably mounted on the correction plate 2. These limiting side plates 3 are slidably mounted on the correction plate 2 via electric slide rails. The distance between the two limiting side plates 3 is adjustable. The multiple limiting side plates 3 form two clamping surfaces, and the distance between them is gradually adjusted according to the patient's scoliosis, gradually correcting the scoliosis. This design can adapt to various types of spinal curvature. During the correction process, some discomfort may occur (within the normal range and not due to overcorrection). The patient may instinctively stand up, which can affect the correction effect (spinal correction requires continuous and stable external force to help the spine gradually return to its normal shape. When the patient frequently stands up, it interrupts the continuous corrective force applied to the spine by the correction device). Taking the arc-shaped correction frame as an example, it adjusts the curvature and tilt angle of the correction plate 2 to fit the patient's spinal curve and apply pressure. The act of standing up interrupts this stable pressure, and the spine cannot gradually adjust under continuous and effective force, hindering the correction process, making it difficult to achieve the expected correction effect, and also interfering with the rhythm of correction. Therefore, a pressing mechanism is designed, as follows: a pressing mechanism is installed on the limiting side plate 3. The pressing mechanism is used to press the patient's chest against the arc-shaped correction front. The pressing mechanism presses down on the patient's chest position, reducing the patient's ability to stand up and ensuring the correction effect.

[0038] like Figure 2 , Figure 3 and Figure 4As shown, the adjustment mechanism includes a semi-circular frame 4, an electric telescopic rod 5, a connecting plate 6, and an adjustment assembly. The semi-circular frame 4 is fixedly installed on the base plate 1. There are multiple electric telescopic rods 5, all of which are installed on the semi-circular frame 4. The connecting plate 6 is installed on the output shaft of the electric telescopic rod 5. The correction plate 2 is installed on the side of the connecting plate 6 away from the electric telescopic rod 5. The adjustment assembly is used to adjust the tilt angle of the connecting plate 6 on the electric telescopic rod 5. By controlling the telescopic length of the electric telescopic rod 5, the position of the connecting plate 6 can be changed, thereby adjusting the curvature of the arc-shaped correction surface formed by the correction plate 2 supported by multiple connecting plates 6. The adjustment assembly is used to adjust the tilt angle of the connecting plate 6 on the electric telescopic rod 5 so that the correction plate 2 can better conform to the physiological curve of the patient's spine and improve the correction effect.

[0039] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adjustment assembly includes a swivel ball 8 and a slider 9; two electric telescopic rods 5 are located below a connecting plate 6, and the two electric telescopic rods 5 drive the connecting plate 6 to rise and fall. The swivel ball 8 is fixedly mounted on the output shaft of the electric telescopic rods 5. The slider 9 has a ball groove, and multiple auxiliary balls 10 are rotatably mounted in the ball groove. The swivel ball 8 is located in the ball groove, and the swivel ball 8 and the multiple auxiliary balls 10 roll in cooperation. The auxiliary balls 10 surround the outer periphery of the swivel ball 8, allowing the swivel ball 8 to rotate flexibly. The bottom surface of the connecting plate 6 is along the length of the connecting plate 6. A transverse groove is provided to slide in conjunction with the slider 9 (in actual operation, only one slider 9 is needed on one connecting plate 6). When adjusting the tilt of the connecting plate 6 (correction plate 2), the extension lengths of the two electric telescopic rods 5 are inconsistent, and the distance between the two universal balls 8 changes. At this time, the slider 9 slides in the transverse groove. The cooperation between the universal balls 8 and the auxiliary ball 10, as well as the setting of the slider 9 and the transverse groove, makes the tilt angle adjustment of the connecting plate 6 smoother and more precise, which can better fit the complex curve of the patient's spine and improve the comfort and effect of correction.

[0040] like Figure 4 , Figure 5 , Figure 6 and Figure 11As shown, the adjustment assembly also includes a micro motor 11, a hexagonal block 12, and a universal joint 13. The micro motor 11 is installed inside the universal ball 8. The inner wall of the ball groove has a hexagonal hole 14 that slides with the hexagonal block 12. The output shaft of the micro motor 11 passes through the universal ball 8 and extends into the hexagonal hole 14. The diameter of the output shaft of the micro motor 11 is smaller than the diameter of the hexagonal hole 14. The universal joint 13 connects the output shaft of the micro motor 11 and the hexagonal block 12. When adjusting the curvature of the curved correction surface, the micro motor 11 rotates through its output shaft. The universal joint 13 and the hexagonal block 12 rotate synchronously. Since the hexagonal block 12 can only slide within the hexagonal hole 14, the hexagonal block 12 drives the connecting plate 6 to rotate synchronously. When adjusting the tilt of the correction plate 2 (perpendicular to the curvature direction), the output shafts of the two electric telescopic rods 5 extend at different lengths, causing the correction plate 2 and the connecting plate 6 to tilt. This will cause the hexagonal block 12 to tilt synchronously. At this time, the universal joint 13 rotates to ensure the tilt of the connecting plate 6 and the correction plate 2, ensuring better fit to the patient's spinal curve, resulting in a better gradual correction effect.

[0041] like Figure 1 , Figure 2 and Figure 7 As shown, the clamping mechanism includes a pressure belt 15, a first lifting component, a second lifting component, and a reset component. Two limiting side plates 3 on one of the correction plates 2 are each provided with a lifting groove. The first and second lifting components are slidably installed in the two lifting grooves. One end of the pressure belt 15 is wound inside the first lifting component, and the other end passes through the second lifting component. When the other end of the pressure belt 15 is pulled, the first and second lifting components move downwards synchronously. In specific operation, it can be adapted to the patient's physical condition. During operation, the patient can grasp one end of the pressure belt 15 to operate it, or a caregiver or medical staff can pull it. There are two reset components, which are used to drive the first and second lifting components to slide and reset, respectively, facilitating future use.

[0042] like Figure 1 and Figure 8 As shown, the first lifting assembly includes a winding shaft 16, a first lifting block 17, a first gear 18, and a spring 19. The winding shaft 16 rotatably passes through the first lifting block 17. A winding groove is provided inside the first lifting block 17. One end of the pressure belt 15 is connected to the winding shaft 16 and wound into the winding groove. A first vertical groove is provided on the inner wall of the lifting groove, which slides with the winding shaft 16. The first gear 18 is fitted onto the end of the winding shaft 16. A first rolling groove is provided in the first vertical groove, which slides with the first gear 18. The first gear 18 meshes with one side of the inner wall of the rolling groove. Figure 2 and Figure 8As shown, in actual operation, pulling the pressure belt 15 causes it to unwind on the winding shaft 16. The unwinding winding shaft 16 rotates, which in turn drives the first gear 18 to rotate synchronously. Since the first gear 18 meshes with the inner wall of the first rolling groove, the first gear 18 rolls downward within the first rolling groove. During the downward movement, the pressure belt 15 descends and presses against the patient's chest. The first lifting block 17 also has an installation groove. The outer end of the spring 19 is fixedly connected to the inner wall of the installation groove, and the inner end of the spring 19 is fixedly connected to the winding shaft 16. The spring 19 can easily rewind the pressure belt 15 for convenient use next time. In addition, the force of the spring 19 is constant, so no additional force is needed to pull the spring 19 when pulling, making the operation labor-saving and convenient.

[0043] like Figure 9 and Figure 10 As shown, the second lifting assembly includes an auxiliary shaft 20, a second lifting block 21, and a second gear 22. The auxiliary shaft 20 rotatably passes through the second lifting block 21, and the pressure belt 15 slides through the second lifting block 21, with the pressure belt 15 slidingly rubbing against the outer periphery of the auxiliary shaft 20. A second vertical groove is provided on the side wall of the lifting slot, which slides into the second lifting block 21. The second gear 22 is fitted onto the end of the auxiliary shaft 20. A second rolling groove is provided in the second vertical groove, which slides into the second gear 22. The second gear 22 meshes with one inner wall of the second rolling groove. The working principle of the second lifting assembly is the same as that of the first lifting assembly. The components work on a similar principle. When the pressure belt 15 is pulled, the friction between the pressure belt 15 and the auxiliary shaft 20 (a toothed mesh can also be set between the pressure belt 15 and the auxiliary shaft 20 to increase the friction) drives the second gear 22 to rotate. The second gear 22 rotates, and the inner wall of the second rolling groove cooperates to achieve descent. The two lifting mechanisms descend synchronously, pressing down on the patient's chest and reducing the need for the patient to get up. At the same time, this structure is not prone to failure and makes it easier for the patient to get up in case of an accident, reducing the risk of irreversible damage.

[0044] like Figure 9 and Figure 10As shown in the diagram, in practice, to facilitate the passage of the pressing belt 15 through the second lifting block 21, a placement groove is provided on the second lifting block 21. The pressing block 23 is removed, the pressing belt 15 is placed in the placement groove, and then the pressing block 23 is reinstalled. At this time, the pressing roller 24 and the auxiliary shaft 20 clamp the pressing belt 15, increasing the friction between the pressing belt 15 and the auxiliary shaft 20. The second lifting assembly also includes a pressing block 23, a pressing roller 24, a mounting pin 25, a mounting spring 26, and a pressing element 27. The second lifting block 21 has a placement groove, and the pressing block 23 is detachably installed in the placement groove. The pressing roller 24 is rotatably installed on the pressing block 23. When the pressing block 23 is installed in the placement groove, the pressing roller 24 and the auxiliary shaft 20 clamp the pressing belt 15. Both sides of the pressing block 23 have openings for storage. The mounting pin 25 has a storage slot, and the two storage slots are connected. The two side walls of the lifting slot are provided with mounting holes that are compatible with the mounting pin 25. The mounting spring 26 is located in the storage slot, and the two ends of the mounting spring 26 are respectively connected to the two mounting pins 25. The side of the mounting pin 25 is fixedly connected with a triangular block 28. The pressing member 27 is slidably installed in the storage slot. One end of the pressing member 27 passes through the clamping block 23 and extends to the outside of the clamping block 23. The two inclined surfaces on the pressing member 27 are respectively slidably engaged with the triangular blocks 28 on the side of the two mounting pins 25. When removing the clamping block 23, the two pressing members 27 are pinched, and the two pressing members 27 slide in the storage slot. The inclined surfaces of the triangular blocks 28 and the inclined surfaces of the pressing members 27 slidely engage, so that the two mounting pins 25 retract into the storage slot. The clamping block 23 can then be removed. The operation is simple and convenient.

[0045] like Figure 8 and Figure 9 As shown, the reset assembly includes a reset sleeve 29 and a reset spring 30. The reset sleeve 29 is rotatably mounted on the end of the auxiliary shaft 20. A reset groove is provided in the limiting side plate 3 to slide and engage with the reset sleeve 29. The reset spring 30 is located in the reset groove, and both ends of the reset spring 30 abut against the inner wall of the end of the reset sleeve 29 and the reset groove, respectively. The rebound force of the reset spring 30 pushes the reset sleeve 29 to slide and reset in the reset groove, thereby driving the reset operation of the two lifting assemblies.

[0046] like Figure 1 , Figure 2 and Figure 4As shown, a limiting telescopic rod 31 is provided between two adjacent connecting plates 6. Both ends of the limiting telescopic rod 31 are connected to movable balls. The two movable balls are rotatably installed on the sides of the two connecting plates 6. The movable balls ensure the flexibility of the connection between the limiting telescopic rod 31 and the connecting plate 6. At the same time, the limiting telescopic rod 31 limits the maximum distance between the connecting plates 6, reduces the occurrence of excessive deformation, and ensures the stability of the structure. It also includes a seat cushion 7. The seat cushion 7 is slidably installed on the base plate 1. The patient sits on the seat cushion 7 for correction, which improves the patient's comfort when adapting to the device and facilitates the smooth progress of the correction work.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
