Description

[0002] Problems such as spinal deformities like scoliosis and kyphosis are relatively common in modern society, seriously affecting the physical health and quality of life of patients.

[0003] Although existing orthopedic spinal correction devices can play a corrective role to a certain extent, there are still many deficiencies. The structural design of some traditional correction devices is relatively simple, and it is difficult to accurately adapt to the complex and diverse spinal physiological characteristics of different patients, resulting in poor correction effects and difficulty in achieving personalized and dynamic precise treatment. For example, the corrector has an integrated structure. When the patient lies on the corrector, the patient's spine lies on the arc-shaped corrector, but its arc cannot be changed, and it cannot adapt to various degrees of spinal curvature (when lying completely on it, for a slightly severe spinal curvature, it may cause discomfort or even pain), and it cannot adjust the correction force and method in real time according to the patient's treatment progress, making it difficult to achieve personalized precise treatment.

Specific embodiments

[0037] Refer to Figures 1 - 11, the present invention provides an orthopedic spinal correction device, including a bottom plate 1, on which an arc-shaped correction frame is installed. The arc-shaped correction frame includes a plurality of correction plates 2 and an adjustment mechanism. The plurality of correction plates 2 can form an arc-shaped correction surface. A soft pad is laid on the correction plate 2 and the edges are chamfered. The adjustment mechanism can adjust the curvature of the arc-shaped correction surface and can also adjust the inclination angle of the correction plate 2. In actual situations, the spinal curvature conditions of patients are different. Assuming that patients with different degrees of spinal curvature use a correction device with the same curvature for correction, the discomfort during correction for patients will also be different. Especially for patients with a larger degree of curvature, sudden correction may even cause spinal injuries. Therefore, the adjustment mechanism adjusts the curvature of the arc-shaped correction surface according to the spinal curvature condition of the patient, so as to adapt to different patients and enable the patients to gradually undergo correction. In addition, patients may also have scoliosis. Therefore, there is the following design. Two limit side plates 3 are slidably installed on the correction plate 2. The limit side plates 3 are slidably installed on the correction plate 2 through electric slide rails. The distance between the two limit side plates 3 is adjustable. Two clamping surfaces are formed by a plurality of limit side plates 3. The distance between the plurality of limit side plates 3 is gradually adjusted according to the scoliosis condition of the patient, and the scoliosis of the patient is gradually corrected. It can adapt to various spinal curvatures for correction. At the same time, during the correction process of the patient, some discomfort may occur (within the normal range, not in the case of overcorrection). The patient's body will instinctively get up, which will 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 often gets up, it interrupts the continuous correction force exerted on the spine by the correction device. Taking the arc-shaped correction frame as an example, it fits the spinal curve and applies pressure by adjusting the curvature and the inclination angle of the correction plate 2. The getting-up behavior interrupts this stable pressure, and the spine cannot be gradually adjusted under the continuous and effective acting force, hindering the correction process and making it difficult to achieve the expected correction effect. It will also interfere with the rhythm of correction). Therefore, a body-pressing mechanism is designed as follows. A pressing mechanism is installed on the limit side plate 3. The pressing mechanism is used to press the patient's chest tightly against the arc-shaped correction surface. The body-pressing mechanism presses the patient's chest position to reduce the getting-up of the patient and ensure the correction effect.

[0038] Such as Figure 2 , Figure 3 and Figure 4As shown in the figure, the adjustment mechanism includes a semi-circular frame 4, electric telescopic rods 5, connecting plates 6 and an adjustment component; the semi-circular frame 4 is fixedly installed on the bottom plate 1, the number of electric telescopic rods 5 is multiple, and multiple electric telescopic rods 5 are all installed on the semi-circular frame 4. The number of connecting plates 6 is the same as that of the electric telescopic rods 5 and is arranged in one-to-one correspondence. The connecting plates 6 are installed on the output shafts of the electric telescopic rods 5. The correction plate 2 is installed on the side of the connecting plate 6 away from the electric telescopic rods 5. The adjustment component is used to adjust the inclination 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, and further the curvature of the arc-shaped correction surface formed by the correction plates 2 supported by multiple connecting plates 6 can be adjusted. The adjustment component is used to adjust the inclination angle of the connecting plate 6 on the electric telescopic rod 5, so that the correction plate 2 can better fit the physiological curve of the patient's spine and improve the correction effect.

[0039] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the adjustment component includes a universal ball 8 and a slider 9; there are two electric telescopic rods 5 below one connecting plate 6, and the two electric telescopic rods 5 drive one connecting plate 6 to move up and down. The universal ball 8 is fixedly installed on the output shaft of the electric telescopic rod 5. A ball groove is provided on the slider 9, and multiple auxiliary balls 10 are rotatably installed in the ball groove. The universal ball 8 is located in the ball groove, and the universal ball 8 is in rolling cooperation with the multiple auxiliary balls 10. The auxiliary balls 10 surround the outer periphery of the universal ball 8, so that the universal ball 8 can rotate flexibly. A transverse movement groove that is slidably matched with the slider 9 is provided on the bottom surface of the connecting plate 6 along the length direction of the connecting plate 6 (in specific operations, only one slider 9 is required on one connecting plate 6). When adjusting the inclination of the connecting plate 6 (correction plate 2), the telescopic 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 movement groove. The cooperation between the universal ball 8 and the auxiliary balls 10 and the setting of the slider 9 and the transverse movement groove make the adjustment of the inclination angle of the connecting plate 6 smoother and more accurate, and can better fit the complex curve of the patient's spine, improving the comfort and effect of the correction.

[0040] As Figure 4 , Figure 5 , Figure 6 and Figure 11As shown in the figure, the adjusting assembly further includes a micro motor 11, a hexagonal block 12 and a universal shaft 13; the micro motor 11 is installed in the universal ball 8, and a hexagonal hole 14 which is slidably matched with the hexagonal block 12 is formed in the inner wall of the ball groove. The output shaft of the micro motor 11 penetrates 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 shaft 13 is connected between the output shaft of the micro motor 11 and the hexagonal block 12. When adjusting the curvature of the arc-shaped correction surface, the output shaft of the micro motor 11 rotates to drive the universal shaft 13 and the hexagonal block 12 to rotate synchronously. Since the hexagonal block 12 can only slide in the hexagonal hole 14, the hexagonal block 12 drives the connecting plate 6 to rotate synchronously. When adjusting the inclination of the correction plate 2 (perpendicular to the curvature direction), the extended lengths of the output shafts of the two electric telescopic rods 5 are inconsistent, and the correction plate 2 and the connecting plate 6 are inclined, which will drive the hexagonal block 12 to be inclined synchronously. At this time, the universal shaft 13 rotates to ensure the inclination of the connecting plate 6 and the correction plate 2, so as to ensure better fitting with the spinal curve of the patient and make the gradual correction effect better.

[0041] As Figure 1 , Figure 2 and Figure 7 As shown in the figure, the pressing mechanism includes a pressing belt 15, a first lifting assembly, a second lifting assembly and a reset assembly; lifting grooves are respectively formed in the two limiting side plates 3 on one of the correction plates 2. The first lifting assembly and the second lifting assembly are respectively slidably installed in the two lifting grooves. One end of the pressing belt 15 is wound in the first lifting assembly, and the other end of the pressing belt 15 passes through the second lifting assembly. When pulling the other end of the pressing belt 15, the first lifting assembly and the second lifting assembly move downward synchronously; in specific operations, it can be adapted according to the physical condition of the patient. During the operation, the patient can hold one end of the pressing belt 15 to operate by himself, or the accompanying personnel or medical staff can pull and operate. The number of the reset assemblies is two, and the two reset assemblies are respectively used to drive the first lifting assembly and the second lifting assembly to slide and reset. The reset assembly drives the two lifting assemblies to slide and reset, which is convenient for the next use.

[0042] As Figure 1 and Figure 8 As shown in the figure, the first lifting assembly includes a winding shaft 16, a first lifting block 17, a first gear 18 and a clockwork spring 19; the winding shaft 16 rotatably penetrates through the first lifting block 17. A winding groove is formed in the first lifting block 17. One end of the pressing belt 15 is connected to the winding shaft 16 and wound in the winding groove. A first vertical groove which is slidably matched with the winding shaft 16 is formed in the inner wall of the lifting groove. The first gear 18 is sleeved at the end of the winding shaft 16. A first rolling groove which is slidably matched with the first gear 18 is formed in the first vertical groove. The first gear 18 meshes with one side inner wall of the rolling groove. As Figure 2 and Figure 8As shown, during actual operation, when the body-pressing belt 15 is pulled, since the body-pressing belt 15 is unrolled on the winding shaft 16, the rotating winding shaft 16 rotates, and the rotating winding shaft 16 drives the first gear 18 to rotate synchronously. Since the first gear 18 meshes with the inner wall of one side of the first rolling groove, the first gear 18 rolls downward in the first rolling groove. During the downward movement, the body-pressing belt 15 will descend and press on the chest position of the patient. An installation groove is also provided in the first lifting block 17. The outer ring end of the clockwork spring 19 is fixedly connected to the inner wall of the installation groove, and the inner ring end of the clockwork spring 19 is fixedly connected to the winding shaft 16. The clockwork spring 19 can conveniently wind back the body-pressing belt 15 for convenient reuse. In addition, the acting force of the clockwork spring 19 is constant. When pulling, there is no need to apply additional force to pull the clockwork spring 19, and the operation is labor-saving and convenient.

[0043] As Figure 9 and Figure 10 shown, the second lifting assembly includes an auxiliary shaft 20, a second lifting block 21 and a second gear 22; the auxiliary shaft 20 rotates through the second lifting block 21, the body-pressing belt 15 slides through the second lifting block 21, and the body-pressing belt 15 has a sliding friction with the outer periphery of the auxiliary shaft 20. A second vertical groove for sliding cooperation with the second lifting block 21 is provided on the side wall of the lifting groove. The second gear 22 is sleeved on the end of the auxiliary shaft 20. A second rolling groove for sliding cooperation with the second gear 22 is provided in the second vertical groove. The second gear 22 meshes with the inner wall of one side of the second rolling groove. The working principle of the second lifting assembly is similar to that of the first lifting assembly. When the body-pressing belt 15 is pulled, due to the friction force between the body-pressing belt 15 and the auxiliary shaft 20 (teeth can also be provided between the body-pressing belt 15 and the auxiliary shaft 20 to increase the friction force), the second gear 22 is driven to rotate, enabling the second gear 22 to drive the second gear 22 to rotate. The second gear 22 cooperates with the inner wall of the second rolling groove to achieve descent. The two lifting mechanisms descend synchronously to press on the chest of the patient, reducing the patient's getting up. At the same time, this structure is not prone to failure, and in case of an accident, it is also convenient for the patient to get up, reducing irreversible damage.

[0044] As Figure 9 and Figure 10As shown in [relevant figure], in addition, in actual situations, to facilitate the passing 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 installed. 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 further includes a pressing block 23, a pressing roller 24, a mounting pin 25, a mounting spring 26, and a pressing member 27. A placement groove is provided on the second lifting block 21, 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. Receiving grooves capable of receiving the mounting pins 25 are provided on both sides of the pressing block 23, and the two receiving grooves communicate with each other. Mounting holes adapted to the mounting pins 25 are provided on both side walls of the lifting groove. The mounting spring 26 is located in the receiving groove, and both ends of the mounting spring 26 are respectively connected to the two mounting pins 25. A triangular block 28 is fixedly connected to the side surface of the mounting pin 25. The pressing member 27 is slidably installed in the receiving groove, and one end of the pressing member 27 penetrates through the pressing block 23 and extends to the outside of the pressing block 23. The two inclined surfaces on the pressing member 27 are respectively in sliding cooperation with the triangular blocks 28 on the side surfaces of the two mounting pins 25. When disassembling the pressing block 23, pinch the two pressing members 27, and the two pressing members 27 slide in the receiving groove. The inclined surfaces of the triangular block 28 and the pressing member 27 are in sliding cooperation, so that the two mounting pins 25 retract into the receiving groove, and the pressing block 23 can be removed. The operation is simple and convenient.

[0045] As Figure 8 and Figure 9 shown in [relevant figure], the reset assembly includes a reset sleeve 29 and a reset spring 30. The reset sleeve 29 is rotatably sleeved on the end of the auxiliary shaft 20. A reset sliding groove in sliding cooperation with the reset sleeve 29 is provided in the limit side plate 3. The reset spring 30 is located in the reset sliding groove, and both ends of the reset spring 30 respectively abut against the reset sleeve 29 and the inner wall of the end of the reset sliding groove. The reset sleeve 29 is driven to slide and reset in the reset sliding groove by the rebounding force of the reset spring 30, thereby driving the reset work of the two lifting assemblies.

[0046] As Figure 1 , Figure 2 and Figure 4As shown in the figure, a limiting telescopic rod 31 is arranged between two adjacent connecting plates 6. Moving balls are connected to both ends of the limiting telescopic rod 31. The two moving balls are respectively rotatably installed on the sides of the two connecting plates 6. The moving balls ensure the flexibility of the connection between the limiting telescopic rod 31 and the connecting plates 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, ensures the stability of the structure, and further includes a cushion 7; the cushion 7 is slidably installed on the bottom plate 1. The patient sits on the cushion 7 for correction, which improves the comfort of the patient when adapting to the device and is conducive to the smooth progress of the correction work.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
