Description

Technical Field

[0001] The present invention relates to the technical field of bone orthopedic devices, and more specifically, to a wearable head, neck and chest correction device based on augmented reality technology. Background Art

[0002] Clinically, most patients suffer from pain in the cervical spine, chest and back, which is mostly related to bad posture and long-term sitting at a desk. In addition, adolescents will develop scoliosis during their growth and development. At this time, patients can use wearable corrective devices to correct their bad posture.

[0003] In the prior art, the announcement number "CN114886635A" is "A spinal surgical nursing correction treatment", which is achieved by setting a waist ring, a chest ring and an arm ring. The left and right ends of the front side of the waist ring and the chest ring are rotated with a correction base, and the upper and lower corresponding correction bases are connected with a correction telescopic rod. A correction base plate is fixed in the middle of the front side of the waist ring and the chest ring, and a massage box is respectively slid between the left and right ends of the two correction base plates. The device can achieve limited correction of the spine while also providing a variety of correction methods for the spine through massage, which makes up for the defects of the existing fixed sleeves and correction belts.

[0004] In the correction of scoliosis during the growth and development period of adolescents, it is necessary to use augmented reality technology to adjust the size, angle and direction of the correction force according to the specific conditions of the patient's daily sitting, standing and walking. For example, in the early stage of correction, a relatively small correction force is applied according to the severity of the scoliosis and the flexibility of the spine to avoid excessive pressure on the spine and surrounding tissues. As the spine gradually adapts, the correction force can be appropriately increased to further promote the correction effect. However, in the above-mentioned prior art, auxiliary correction is performed by setting a shuttle-shaped massage stick to massage the patient's spine, and the massage strength of the shuttle-shaped massage stick is fixed, and the size of the correction force cannot be adjusted according to the specific conditions of the patient, which makes the application range of the device narrow.

[0014] Optionally, the spacing of the adjusting grooves matches the outer diameter of the main pull rod, and the avoidance groove matches the flat rubber band.

In this process, it should be noted that a signal generating module is provided inside the motion capture sensor. When the motion capture sensor captures the current posture deviation, the signal generating module can be connected to the AR glasses for real-time signal connection, and the current posture deviation state is fed back to the AR glasses. When the patient adjusts the body posture, the AR glasses can compare the real-time spatial position of the patient's cervical spine, thoracic spine, and lumbar spine with the standard posture stored in the AR glasses, so as to facilitate the patient to adjust the current posture, thereby enabling the patient to correct the posture in time. In this process, multiple groups of main correction blocks respectively apply force to the convex side of the user's spine under the resetting action of multiple groups of flat rubber bands. The setting of the force application point, in conjunction with the reaction force points on the shoulders and waist of the body, forms a mechanical balance system. By adjusting the magnitude and direction of these forces, a continuous and stable correction force is applied to the scoliotic spine, prompting the spine to gradually return to a normal physiological curvature. This correction force can effectively prevent the further development of scoliosis.

[0019] By setting up an adjustment mechanism, as the spine gradually adapts, the flat rubber band is stretched and tightened by rotating the reel to increase its resetting force, thereby appropriately increasing the correction force at the force application point to further promote the correction effect.

[0020] By setting up a fixing mechanism and moving the pull plate to separate it from the rectangular limiting hole, the connection between the mounting base and the mounting shell can be released, and then the position of the main correction block can be adjusted by moving the mounting base up and down. When this device is used to correct S-shaped scoliosis or C-shaped scoliosis, due to different force application points, the height positions of multiple sets of main correction blocks can be adjusted by repeating the above operations to improve the applicability of the correction device.

[0039] like Figures 1 to 9 As shown, an embodiment of the present invention provides a wearable head, neck and chest correction device based on augmented reality technology, including a waistcoat 1, the bottom of the waistcoat 1 is provided with a wearing mechanism for performing correction operations on the patient, an adjustment mechanism, the adjustment mechanism is used to adjust the correction force, the adjustment mechanism is connected to the wearing mechanism, a fixing mechanism, the fixing mechanism is used to connect the adjustment mechanism with the wearing mechanism, the fixing mechanism is connected to the adjustment mechanism and the wearing mechanism, the wearing mechanism includes an upper fixing belt 2 fixedly connected to the bottom of the waistcoat 1, the bottom of the upper fixing belt 2 is fixedly connected to a back connecting belt 8, the bottom of the back connecting belt 8 is fixedly connected to a lower fixing belt 3, the two sides of the back connecting belt 8 are fixedly connected to side support belts 4, the waistcoat 1, the side The inner walls of the support belt 4 and the lower fixing belt 3 are both provided with motion capture sensors 5, the inner walls on the same side of the upper fixing belt 2 and the lower fixing belt 3 are both provided with Velcro hook surfaces 6, and the surfaces on the other sides of the upper fixing belt 2 and the lower fixing belt 3 are both provided with Velcro fur surfaces 7. The wearing mechanism also includes a mounting shell 9 arranged on the outer wall of the back connecting belt 8, and a plurality of main pull rods 14 are arranged inside the back connecting belt 8. One side of the main pull rod 14 is rotatably connected to a main correction block 13 located inside the mounting shell 9. The main correction block 13 is provided with a limiting strip 15 on one side of the outer wall of the main pull rod 14, and the interior of the main correction block 13 is provided with a flat rubber band 11 fixedly connected to the limiting strip 15, and the other side of the flat rubber band 11 is fixedly connected to a winding disk 19.

[0040] Before using the device, the patient first wears the AR glasses, and then puts the waistcoat 1 on the shoulders, and fixes the correction device to the user's shoulders by tightening the upper fixing strap 2 and the Velcro hook surface 6 and the Velcro fur surface 7 arranged on the upper fixing strap 2. Then, by tightening the lower fixing strap 3, the lower fixing strap 3 is made to fit the user's waist, and the side support strap 4 is driven to fit between the user's ribs and waist. At this time, multiple groups of motion capture sensors 5 are in contact with the user's body. In this way, when the user's posture deviates from the normal range and exceeds a certain threshold, the motion capture sensor 5 will capture the current deviation of the posture. In this process, it should be noted that a signal generating module is arranged inside the motion capture sensor 5. When the motion capture sensor 5 captures the current deviation of the posture When the patient adjusts his body posture, the AR glasses can compare the real-time spatial positions of the patient's cervical, thoracic and lumbar vertebrae with the standard posture stored in the AR glasses, so as to facilitate the patient to adjust the current posture and thus enable the patient to correct the posture in time. The multiple groups of main correction blocks 13 in the present application respectively apply force to the convex side of the user's spine under the resetting action of the multiple groups of flat rubber bands 11. The setting of the force application points, together with the reaction force points on the shoulders and waist of the body, form a mechanical balance system. By adjusting the size and direction of these forces, a continuous and stable corrective force is applied to the scoliotic spine, prompting the spine to gradually return to its normal physiological curvature. This corrective force can effectively prevent the further development of scoliosis.

[0041] like Figures 2 to 9 As shown, the adjustment mechanism includes a mounting base 10 arranged on the outer wall of one end of the mounting shell 9 away from the back connecting belt 8, a fixed shaft 20 is rotatably connected to the inside of one side of the mounting base 10, the winding disk 19 is fixedly connected to the top of the fixed shaft 20, and a ratchet 21 is fixedly connected to the bottom of the fixed shaft 20, and an arc block 22 rotatably connected to the mounting base 10 is arranged on the outside of the ratchet 21, and the adjustment mechanism also includes a convex block 25 arranged on one side of the arc block 22 and fixedly connected to the mounting base 10, and the arc block 22 is connected to the convex block 25. A first spring 24 is arranged between the blocks 25, a column 23 is fixedly connected to the bottom of the arc block 22, an outer wall of the ratchet 21 is arranged as a semi-arc structure, an end face of the semi-arc structure is abutted against the arc block 22, one end of the first spring 24 is fixed to the protrusion 25, and the other end is abutted against the arc block 22, a plurality of groups of secondary pull rods 18 are arranged inside and outside the mounting shell 9, the plurality of groups of secondary pull rods 18 are respectively located above the plurality of groups of main pull rods 14, and the adjusting mechanism, the wearing mechanism and the fixing mechanism are also arranged outside the plurality of groups of secondary pull rods 18.

[0042] As the spine gradually adapts, the flat rubber band 11 is stretched and tightened by rotating the winding disk 19. It should be noted that when the flat rubber band 11 is stretched, within the elastic limit, the flat rubber band 11 will produce elastic deformation. According to Hooke's law F=kx (where F is the elastic force, k is the elastic coefficient, and x is the deformation variable), as the deformation variable increases, the elastic force will increase, thereby increasing its reset force, so as to appropriately increase the correction force of the force application point to further promote the correction effect. In this process, the rotation of the winding disk 19 drives the fixed shaft 20 to rotate, and the rotation of the fixed shaft 20 drives the ratchet 21 to rotate. The rotation of the ratchet 21 causes the arc surface of its outer wall to contact the arc block 22. At this time, the ratchet 21 can rotate, and when the correction force adjustment of the force application point is completed, the end face of the outer wall of the ratchet 21 is engaged with the arc block 22, which can prevent the ratchet 21 from reversing under the reset action of the flat rubber band 11 and affecting the normal use of the correction device.

[0043] Before using the main correction block 13 to perform correction operations, it is necessary to rotate the main pull rod 14 so that the stop block 17 on the outer wall of the main pull rod 14 is aligned with the movable slide groove 26 to release the limit on the main correction block 13, after completing the height adjustment of the main correction block 13.

[0044] By pulling the column 23 to drive the arc block 22 to rotate, the arc block 22 is separated from the ratchet 21, and the limiting operation on the flat rubber band 11 can be released. At this time, pulling the main pull rod 14 can drive the main correction block 13 to reset, and when the block 17 passes through the movable slide groove 26, the main pull rod 14 is rotated to make the block 17 and the movable slide groove 26 misaligned with each other, and the block 17 and the retaining ring 16 are against each other, so as to complete the resetting operation of the main correction block 13, so as to facilitate the user to wear the correction device for the second time.

[0045] like Figures 4 to 9As shown, the fixing mechanism includes an avoidance groove 32 opened on the outer wall of the mounting shell 9, and an avoidance groove 32 is provided between the avoidance groove 32 and the inner wall end face of the mounting shell 9. The top of the mounting base 10 away from the winding disk 19 is fixedly connected with a retaining ring 16, and the outer wall of the main pull rod 14 is fixedly connected with a stopper 17, and the interior of the retaining ring 16 is provided with a movable slide groove 26 matching the stopper 17. The fixing mechanism also includes a connecting rod 27 that runs through the middle of the mounting base 10. The outer wall of the rod 27 is fixedly connected to a pull plate 30 away from the mounting shell 9, the outer wall of the connecting rod 27 is sleeved with a second spring 29, the second spring 29 is located between the pull plate 30 and the mounting base 10, the inner wall of the mounting shell 9 is equidistantly provided with a plurality of groups of rectangular limiting holes 12, the outside of the connecting rod 27 is fixedly connected to a rectangular connecting plate 28 extending to the inside of the rectangular limiting hole 12, and the inside of the mounting base 10 is provided with a rectangular anti-slip groove 33 matching the rectangular connecting plate 28.

[0046] By moving the pull plate 30 to separate from the rectangular limiting hole 12, the connection between the mounting base 10 and the mounting shell 9 can be released, and then the position of the main correction block 13 can be adjusted by moving the mounting base 10 up and down, so that the main correction block 13 corresponds to the convex side of the scoliosis, so that the main correction block 13 can apply force to correct it. During the peak growth period of adolescence, due to the influence of genetic, nutritional or endocrine factors, the chondrocytes of the growth plate on one side proliferate faster than the other side, which will cause the spine to gradually bend toward the slower growing side. If this growth imbalance exists simultaneously in the spine in different areas but with different degrees and directions, it may form an S-shaped scoliosis; if it is only obvious in a certain area, it may form a C-shaped scoliosis. When the present device is used to correct S-shaped scoliosis or C-shaped scoliosis, due to different force application points, the height positions of multiple groups of the main correction blocks 13 can be adjusted by repeating the above operation to improve the applicability of the correction device.

[0047] After completing the height adjustment operation of the main correction block 13, the pull plate 30 is inserted into the interior of the rectangular limiting hole 12 under the reset action of the second spring 29 to complete the connection and fixation between the mounting base 10 and the mounting shell 9, so that the user can use the correction device.

[0048] like Fig. 9 As shown, the spacing of the adjusting slots 31 matches the outer diameter of the main pull rod 14 , and the avoiding slots 32 matches the flat rubber band 11 .

[0049] This structural arrangement enables the main pull rod 14 and the flat rubber band 11 to move synchronously when the main correction block 13 is adjusted in height.

[0050] The workflow of the technical solution of the present invention is as follows:

[0051] First, by moving the pull plate 30 and separating it from the rectangular limiting hole 12, the connection between the mounting base 10 and the mounting shell 9 can be released, and then the position of the main correction block 13 can be adjusted by moving the mounting base 10 up and down, so that the main correction block 13 corresponds to the convex side of the scoliosis, so that the main correction block 13 can apply force to correct it. During the peak growth period of adolescence, due to the influence of genetic, nutritional or endocrine factors, the chondrocytes of the growth plate on one side proliferate faster than the other side, which will cause the spine to gradually bend toward the slower growing side. If this growth imbalance exists simultaneously in different areas of the spine, but the degree and direction are different, it may form an S-shaped scoliosis; if it is only obvious in a certain area, it may form a C-shaped scoliosis. When the present device is used to correct S-shaped scoliosis or C-shaped scoliosis, due to the different force application points, the height position of multiple sets of main correction blocks 13 can be adjusted by repeating the above operation.

[0052] After completing the height adjustment operation of the main correction block 13, the pull plate 30 is inserted into the inside of the rectangular limiting hole 12 under the reset action of the second spring 29 to complete the connection and fixation between the mounting base 10 and the mounting shell 9, and then the user can use the correction device; the user first puts the waistcoat 1 on the shoulder, and then tightens the upper fixing belt 2, and completes the fixation of the correction device to the user's shoulder through the Velcro hook surface 6 and the Velcro fur surface 7 set on the upper fixing belt 2, and then tightens the lower fixing belt 3 to make the lower fixing belt 3 fit the user's waist, and drive the side support belt 4 to fit between the user's ribs and waist. At this time, multiple groups of motion capture sensors 5 are in contact with the user's body. In this way, when the user's posture deviates from the normal range and exceeds a certain threshold, the motion capture sensor 5 will capture the current deviation of the body posture. In this process, it should be noted that the motion capture sensor 5 has a A signal generating module is provided. When the motion capture sensor 5 detects that the current posture is deviated, the signal generating module can establish a real-time signal connection with the AR glasses, and feed back the current posture deviation state to the AR glasses. When the patient adjusts the body posture, the AR glasses can compare the real-time spatial position of the patient's cervical spine, thoracic spine and lumbar spine with the standard posture stored in the AR glasses, so as to facilitate the patient to adjust the current posture, thereby enabling the patient to correct the posture in time. In this process, multiple groups of main correction blocks 13 respectively apply force to the convex side of the user's spine under the resetting action of multiple groups of flat rubber bands 11. The setting of the force application points, together with the reaction force points on the shoulders and waist of the body, form a mechanical balance system. By adjusting the size and direction of these forces, a continuous and stable corrective force is applied to the scoliotic spine, prompting the spine to gradually return to its normal physiological curvature. This corrective force can effectively prevent the further development of scoliosis.

[0053] As the spine gradually adapts, the flat rubber band 11 is stretched and tightened by rotating the winding disk 19. When the flat rubber band 11 is stretched, within the elastic limit, the flat rubber band 11 will produce elastic deformation, and the elastic force will increase, thereby increasing its reset force, so as to appropriately increase the correction force of the force application point to further promote the correction effect. In this process, the rotation of the winding disk 19 drives the fixed shaft 20 to rotate, and the rotation of the fixed shaft 20 drives the ratchet 21 to rotate. The rotation of the ratchet 21 causes the arc surface of its outer wall to contact the arc block 22. At this time, the ratchet 21 can rotate, and when the correction force adjustment of the force application point is completed, the end face of the outer wall of the ratchet 21 is engaged with the arc block 22, which can prevent the ratchet 21 from reversing under the reset action of the flat rubber band 11, thereby affecting the normal use of the correction equipment.

[0054] Before using the main correction block 13 to perform the correction operation, it is necessary to rotate the main pull rod 14 so that the block 17 on the outer wall of the main pull rod 14 is aligned with the movable slide groove 26 to release the limit on the main correction block 13. After completing the height adjustment of the main correction block 13, the arc block 22 is driven to rotate by pulling the column 23 to separate the arc block 22 from the ratchet 21 to release the limit operation on the flat rubber band 11. At this time, pulling the main pull rod 14 can drive the main correction block 13 to reset, and when the block 17 passes through the movable slide groove 26, rotate the main pull rod 14 so that the block 17 and the movable slide groove 26 are misaligned with each other, and the block 17 is against the retaining ring 16, so that the resetting operation of the main correction block 13 can be completed, so that the user can use the correction device for the second time.

[0055] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
