Description

Technical Field

[0001] This invention relates to the field of assistive devices for spinal rehabilitation, specifically a fixation assistive device for spinal rehabilitation. Background Technology

[0002] When important parts of the spine, such as the thoracic and lumbar vertebrae, are damaged or become dysfunctional, external support can provide stability, postural correction, and pain relief, creating conditions for tissue repair and functional rehabilitation. For chronic diseases such as lumbar muscle strain and myofascitis of the thoracic and back, patients are prone to pain due to muscle fatigue during daily activities. Assistive devices can provide dynamic support, distribute spinal pressure, and relieve muscle load.

[0003] For example, patent CN221205811U discloses a spinal rehabilitation fixation aid, including: a back plate and a front plate; two symmetrical connecting straps are fixedly connected between the back plate and the front plate, shoulder pads are fixedly connected to the outer walls of the two connecting straps, a connecting groove is opened at the bottom of the shoulder pad, a Velcro strap is fixedly connected to the inner wall of the connecting groove of the shoulder pad, a Velcro hook is glued to the bottom of the Velcro strap, and a heating pad is fixedly connected to the outer wall of the Velcro hook. By using the heating pad, heat stimulation is applied to the sore shoulder area, which can relieve shoulder pain, relax muscles, promote blood circulation, and improve the comfort of use.

[0004] For example, patent CN223196226U discloses a spinal rehabilitation fixation aid, including a first support base and a second support base. An installation device is installed at the rear end of the first support base. An adjustment device is installed at one end of the first and second support bases. An auxiliary support base is installed at the middle of the front end of the adjustment device, and a restraint device is installed at the middle of the rear end of the adjustment device. A set of support frames is installed at the left and right ends of the first and second support bases. Rubber balls are installed at the front ends of the four sets of support frames. By loosening the installation screws on the first and second support bases, the adjustment plate can be moved and adjusted within the adjustment grooves in the first and second support bases as needed. After adjusting to the appropriate position, the installation screws can be screwed back in, thus allowing the device to be adjusted in length according to the user's needs, improving the practicality of the device.

[0005] For example, patent CN114617687B discloses a spinal rehabilitation medical correction aid, including a shoulder fixation plate, a spinal connection plate, and a leg fixation plate. The shoulder fixation plates are symmetrically arranged on both sides of the spinal connection plate. A shoulder fixation strap box is located on the upper surface of the shoulder fixation plate, and a port housing is located below the shoulder fixation strap box. An adjusting winch is located on one side of the port housing. A correction plastic plate is located at the lower end of the shoulder fixation plate. Movable connecting plates are symmetrically arranged on both sides of the upper part of the spinal connection plate. Correction plastic plates are located on both sides of the middle fixation plate. The leg fixation plates are symmetrically arranged on both sides of the spinal connection plate. Each leg fixation plate has two fixing buckles on one side. By providing the port housing, the correction device can be connected to a computer, enabling more precise treatment. The various fixation devices and connecting plates allow for more... The adjustment and correction force needs to be refined. Existing spinal rehabilitation fixation devices can be divided into rigid strong support devices and flexible support devices. Rigid strong support devices have high hardness and sufficient support force, which is suitable for the daytime injury stabilization needs. However, they have a strong pressure when worn and cannot be used directly for nighttime sleep. Flexible support devices can be worn at night, but the support strength is insufficient and it is difficult to provide effective stability protection during daytime activities. The auxiliary effect on injury recovery is limited and cannot cover the full cycle of rehabilitation needs. Moreover, the physiological structure and weight-bearing characteristics of the lumbar spine and thoracic spine are different, and the required support force is different. However, most existing devices adopt a uniform support design, which cannot accurately match the needs of each area. In addition, some devices that can be worn at night have not been optimized for support strength. Excessive support force can easily compress the waist, affecting the body position adjustment and blood circulation during sleep, which is not conducive to sleep.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing assistive devices for spinal rehabilitation. Summary of the Invention

[0007] The purpose of this invention is to provide a fixation aid for spinal rehabilitation, in order to solve the problems mentioned in the background art, such as the inability of some existing spinal rehabilitation fixation aids to simultaneously meet the needs of daytime and nighttime use, the inconvenience of adjusting the support strength for the lumbar and thoracic vertebrae, and the fact that some wearable aids have a large support strength at night, which affects the patient's sleep.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a fixation aid for spinal rehabilitation, comprising a protective vest worn by the patient, a pressure-reducing shoulder strap connected to the protective vest, and a tightening strap on the outside of the protective vest. A thoracic support pad and a lumbar support pad are fixedly installed inside the protective vest on the side closest to the patient's back, with the thoracic support pad positioned above the lumbar support pad. A thoracic support plate and a lumbar support plate are movably installed on the outside of the protective vest on the side closest to the patient's back. Two sets of thoracic and lumbar support plates are symmetrically arranged about the central axis of the protective vest, and the thoracic and lumbar support plates are correspondingly positioned outside the thoracic and lumbar support pads. A locking assembly for quick-connect assembly is provided between the thoracic and lumbar support plates and the thoracic and lumbar support pads. A fixing strap is fixedly connected between the thoracic and lumbar support plates, and the fixing strap is fitted onto the outside of the protective vest. A pressure adjustment mechanism for adjusting the lumbar fixation support is provided between the thoracic and lumbar support plates.

[0009] Preferably, the inner side of the fixing strap is fixed with a barbed hook and loop fastener, and the outer side of the tightening strap is fixed with a loose hook and loop fastener, and the fixing strap is bonded to the tightening strap through the barbed hook and loop fastener and the loose hook and loop fastener.

[0010] Preferably, the locking assembly includes a circular hole on the protective vest, and cylindrical tubes fixed on both the thoracic and lumbar support plates, with the cylindrical tubes engaging with the circular hole; a rotating handle is rotatably connected to the cylindrical tube, and a locking rod is fixed at the end of the rotating handle; both the thoracic and lumbar support plates have circular grooves corresponding to the positions of the locking rods, and the thoracic and lumbar support plates also have strip grooves that communicate with the circular grooves.

[0011] Preferably, the pressure adjustment mechanism includes an upper support rod fixedly installed on the thoracic spine support plate, and a lower support rod fixedly connected to the lumbar spine support plate, with the lower support rod rotatably connected below the upper support rod.

[0012] Preferably, an upper support is vertically fixed to the upper support rod, and an internally threaded cylinder is rotatably connected to the upper support rod; a lower support is vertically fixed to the lower support rod, and a rotating frame is rotatably connected to the lower support rod, and an externally threaded rod is rotatably connected to the rotating frame, with the externally threaded rod threaded through and connected to the inside of the internally threaded cylinder.

[0013] Preferably, a linear spring is elastically connected between the upper support rod and the lower support rod, with one end of the linear spring fixedly connected to the upper support rod and the other end slidably connected to the lower support rod.

[0014] Preferably, the lumbar support pad has an inner groove, and a fixed round rod is fixedly connected in the center of the inner groove. Multiple movable round rods are symmetrically arranged above and below the fixed round rod in the inner groove, and the movable round rods slide and fit into the inner groove.

[0015] Preferably, the protective vest is provided with a spacing adjustment structure that adjusts the distribution distance of multiple movable and fixed round rods at equal intervals. Increasing the distribution distance of the movable and fixed round rods can reduce support pressure and aid sleep.

[0016] Preferably, the spacing adjustment structure includes an arc-shaped spring piece elastically connected between adjacent movable and fixed round rods, and a movable groove is provided on the side of the lumbar support pad near the protective vest, with the arc-shaped spring piece passing through the movable groove; a pressure strip is slidably installed in the protective vest, and the pressure strip is attached to the side of the arc-shaped spring piece.

[0017] Preferably, a pressure block is slidably connected through the protective vest, and the pressure block is fixedly connected to the pressure strip; the pressure block is elastically connected to the outside of the protective vest with a limiting spring, and the pressure block is fitted next to the lower support rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the protective vest for spinal rehabilitation can meet the needs of nighttime spinal support and fixation of patients through thoracic and lumbar support pads without affecting the patient's sleep. Furthermore, the protective vest is equipped with thoracic and lumbar support plates on the outside through fixing straps, which can further improve the support strength and meet the needs of daytime patient activities. The combined fixation device is flexible in application and more applicable.

[0019] The thoracic and lumbar support plates are equipped with quick-connect locking components that connect with the thoracic and lumbar support pads. When installing the thoracic and lumbar support pads, the cylindrical tubes on the pads pass through the round holes on the protective vest. The locking rod enters the round groove through the strip groove. Rotating the locking rod causes its rotating fibers to remain in the round groove, thus limiting the installation position of the thoracic and lumbar support pads. This improves the connectivity between the thoracic and lumbar support pads and enhances the overall support strength of the fixation device after combined use, meeting the patient's daily use needs.

[0020] A pressure adjustment mechanism is installed between the thoracic and lumbar support plates to adjust the lumbar fixation support. After the assistive device is assembled, the distance between the upper and lower supports is adjusted by controlling the rotation of the external threaded rod in the internal threaded cylinder. This controls the rotation of the lower support rod connected below the upper support rod, adjusting the support strength of the lower lumbar support plate and lumbar support pad on the patient's lower back. The lumbar spine is the main weight-bearing area of ​​the human spine, and it bears a lot of pressure during daily activities. During rehabilitation, stronger support is needed to maintain stability, limit excessive movement, and promote injury recovery.

[0021] The lumbar support pad is equipped with a fixed round rod and multiple movable round rods. This configuration can further enhance the support for the lumbar region. When using this assistive device at night, the distance between the fixed and movable round rods is smaller, reducing the contact area with the skin and muscles of the lower back, minimizing sleep disturbances caused by discomfort, and helping patients maintain a good sleep state.

[0022] When assembling and installing the lumbar support plate, adjusting the rotation angle of the lower support rod causes it to compress the arc-shaped spring plate by squeezing the pressure block and pressure strip. The arc-shaped spring plate controls multiple movable round rods to move and unfold above and below the fixed round rod, thereby expanding the support range for the lumbar muscles and dispersing the support force from the core area of ​​the lumbar spine to the surrounding area, avoiding local pressure concentration, meeting the needs of patients' daytime activities, and improving the daytime use effect.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figures 1-8The present invention provides the following technical solution: a fixation aid for spinal rehabilitation, comprising a protective vest 1 worn by the patient, a pressure-reducing shoulder strap 2 connected to the protective vest 1, a tightening strap 3 on the outside of the protective vest 1, a thoracic spine support pad 4 and a lumbar spine support pad 5 fixedly installed inside the protective vest 1 on the side close to the patient's back, the thoracic spine support pad 4 being positioned above the lumbar spine support pad 5, and a thoracic spine support plate 6 and a lumbar spine support plate 7 movably installed on the outside of the protective vest 1 on the side close to the patient's back, both the thoracic spine support plate 6 and the lumbar spine support plate 7 being related to... The protective vest 1 has two sets of symmetrically arranged along its central axis, with the thoracic spine support plate 6 and lumbar spine support plate 7 correspondingly positioned outside the thoracic spine support pad 4 and lumbar spine support pad 5. A quick-connect locking assembly 9 is provided between the thoracic spine support plate 6 and lumbar spine support plate 7 and the thoracic spine support pad 4 and lumbar spine support pad 5. A fixing strap 8 is fixedly connected between the thoracic spine support plate 6 and lumbar spine support plate 7, and the fixing strap 8 is fitted onto the outside of the protective vest 1. A pressure adjustment mechanism is provided between the thoracic spine support plate 6 and lumbar spine support plate 7 to adjust the lumbar spine fixation support. A hook-and-loop fastener 81 is fixed to the inner side of the fixing strap 8, and a loop fastener 82 is fixed to the outer side of the tightening strap 3. The fixing strap 8 is adhered to the tightening strap 3 through the hook-and-loop fastener 81 and the loop fastener 82.

[0043] Please see Figures 2-11 The locking assembly 9 includes a circular hole 91 on the protective vest 1, and cylindrical tubes 92 fixed on both the thoracic support plate 6 and the lumbar support plate 7, with the cylindrical tubes 92 and the circular hole 91 engaging through each other. A rotating handle 93 is connected to the cylindrical tube 92 with damping rotation, and a locking rod 94 is fixed at the end of the rotating handle 93. Both the thoracic support plate 6 and the lumbar support plate 7 have circular grooves 95 corresponding to the position of the locking rod 94, and the thoracic support plate 6 and the lumbar support plate 7 also have strip grooves 96 that communicate with the circular grooves 95.

[0044] Please see Figures 12-14 The pressure adjustment mechanism includes an upper support rod 10 fixedly installed on the thoracic support plate 6, a lower support rod 11 fixedly connected to the lumbar support plate 7, and the lower support rod 11 rotatably connected below the upper support rod 10; an upper support 12 is vertically fixed on the upper support rod 10, and an internally threaded cylinder 13 is rotatably connected to the upper support 12; a lower support 14 is vertically fixed on the lower support rod 11, a rotating frame 141 is rotatably connected to the lower support 14, and an externally threaded rod 15 is rotatably connected to the rotating frame 141, the externally threaded rod 15 being threaded through and connected to the inside of the internally threaded cylinder 13; a linear spring piece 16 is elastically connected between the upper support rod 10 and the lower support rod 11, one end of the linear spring piece 16 is fixedly connected to the upper support rod 10, and the other end of the linear spring piece 16 is slidably connected to the lower support rod 11.

[0045] This fixation device has two usage modes: daytime and nighttime. When used at night, the protective vest 1 is worn on the patient. The pressure of the protective vest 1 on the body is adjusted by adjusting the tightening strap 3 and the pressure-reducing shoulder strap 2. The thoracic spine support pad 4 and lumbar spine support pad 5 on the protective vest 1 fit and support the patient's thoracic and lumbar spine positions respectively, maintaining the physiological curvature of the lumbar spine and preventing the patient from unconsciously adopting poor posture, so as to ensure comfort and positional adjustability during sleep.

[0046] During daytime use, the thoracic support plate 6 and lumbar support plate 7 are fitted to the outside of the protective vest 1. The cylindrical tubes 92 on the thoracic support plate 6 and lumbar support plate 7 are connected to the circular holes 91 on the protective vest 1. The locking rod 94 on the cylindrical tube 92 passes through the slots 96 opened on the thoracic support pad 4 and lumbar support pad 5, and the locking rod 94 passes through the slots 96 and enters the circular groove 95. The locking rod 94 is controlled to rotate by turning the handle 93, and the locking rod 94 rotates from a vertical position to a horizontal position. The locking rod 94 rotates and locks itself inside the circular groove 95 (a part of the circular groove 95 passes through the thoracic support pad 4 and lumbar support pad 5). The vertebral support pad 5 (after the locking rod 94 rotates, one side extends outside the thoracic vertebral support pad 4 and lumbar vertebral support pad 5) can be quickly connected to the thoracic vertebral support plate 6 and lumbar vertebral support plate 7 through the locking component 9. This allows the thoracic vertebral support plate 6 and lumbar vertebral support plate 7 to be reinforced and supported outside the thoracic vertebral support pad 4 and lumbar vertebral support pad 5, thereby meeting the patient's requirements for spinal support during daytime activities. The fixing strap 8 is attached to the outside of the tightening strap 3 through the hook-and-loop fastener 81 and the loop fastener 82, maintaining the state of the thoracic vertebral support plate 6 and lumbar support plate 7 combined with the thoracic vertebral support pad 4 and lumbar vertebral support pad 5.

[0047] The lumbar spine is the main weight-bearing area of ​​the human spine. It bears a lot of pressure during daily activities and requires stronger support during rehabilitation to maintain stability and limit excessive movement in order to promote injury recovery. Therefore, after installing the thoracic spine support plate 6 and the lumbar spine support plate 7, the support pressure of the lumbar spine support plate 7 is further adjusted according to the patient's needs for lumbar spine support. The external threaded rod 15 is controlled to rotate through the internal threaded cylinder 13, and the distance between the upper support 12 and the lower support 14 is adjusted so that the lower support rod 11 rotates below the upper support rod 10. The lower support rod 11 pushes the lumbar spine support plate 7 closer to the patient's back, thereby increasing the support pressure on the patient's lumbar spine and improving the effect of the assistive device in fixing and supporting the spine.

[0048] Example 2: Please refer to Figure 16 and Figure 17Based on Embodiment 1, a spacing adjustment structure is also disclosed, the specific structure of which is as follows: The lumbar support pad 5 has an inner groove 51, and a fixed round rod 52 is fixedly connected in the center of the inner groove 51. Multiple movable round rods 53 are symmetrically arranged above and below the fixed round rod 52 in the inner groove 51, and the movable round rods 53 are slidably fitted into the inner groove 51. The protective vest 1 is provided with a spacing adjustment structure that adjusts the distribution distance of multiple movable round rods 53 and fixed round rods 52 at equal intervals. Increasing the distribution distance of movable round rods 53 and fixed round rods 52 can reduce support pressure and assist sleep.

[0049] Please see Figures 14-17 The spacing adjustment structure includes an arc-shaped spring piece 54 elastically connected between adjacent movable round rods 53 and fixed round rods 52. A movable groove 55 is provided on the side of the lumbar support pad 5 near the protective vest 1, and the arc-shaped spring piece 54 is disposed through the movable groove 55. A pressure strip 56 is fitted and slidably installed in the protective vest 1, and the pressure strip 56 is attached to the side of the arc-shaped spring piece 54. A pressure block 17 is slidably connected through the protective vest 1, and the pressure block 17 is fixedly connected to the pressure strip 56. A limit spring piece 18 is elastically connected to the outside of the protective vest 1, and the pressure block 17 is attached to the side of the lower support rod 11.

[0050] The lumbar support pad 5 is equipped with a fixed round rod 52 and multiple movable round rods 53. The fixed round rod 52 and the movable round rods 53 can further support the patient's lumbar spine. After the thoracic support plate 6 and the lumbar support plate 7 are assembled and installed, when the rotation angle of the lower support rod 11 is adjusted, the lower support rod 11 squeezes the pressure block 17 attached to the side, pushing the pressure block 17 through the protective vest 1 and moving towards the patient's back. The pressure block 17 drives the pressure strip 56 to move synchronously, so that the pressure strip 56 presses tightly next to the arc-shaped spring piece 54. The arc-shaped spring piece 54 undergoes elastic deformation, controlling the multiple movable round rods 53 to move and unfold at equal intervals above and below the fixed round rod 52, thereby expanding the overall support range of the fixed round rod 52 and the movable round rod 53, allowing the support force to be dispersed from the core area of ​​the lumbar spine to the surrounding area, avoiding local pressure concentration, and further improving the support effect of the assistive device during daytime use.

[0051] If the patient's symptoms lessen and the need for spinal support pressure decreases during the day, the assistive device can be worn directly at night. If the patient experiences muscle soreness or discomfort in the lumbar region during long-term wear, a fascia gun needle can be applied to the surface of the pressure block 17 (or the patient can sit on a chair and repeatedly squeeze the pressure block 17 by leaning back against the chair). The vibration force of the pressure block 17 is transmitted to the pressure strip 56 and the curved spring 54. The curved spring 54 switches between the squeezing and releasing states, which can control the movable round rod 53 to move and adjust equidistantly around the fixed round rod 52. During the movement, the movable round rod 53 can soothe the patient's back muscles and reduce lower back pain caused by muscle stiffness. Compared with directly applying a fascia gun to the patient's back, the transmitted force is smaller, the movable round rod 53 has a larger and more even range of action, and it is less likely to cause problems such as back muscle damage.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
