Description

Technical Field

[0001] This invention relates to the field of orthopedic spinal injury rehabilitation devices, specifically an auxiliary device for the treatment of orthopedic spinal injuries. Background Technology

[0002] In orthopedic clinical treatment, spinal injuries are a common and serious traumatic disease, often caused by accidental impacts, falls from heights, sports injuries, and other factors. They not only cause back pain and limited mobility, but in severe cases, can damage the spinal cord and nerves, leading to irreversible consequences such as limb paralysis. Rehabilitation after a spinal injury is a long-term process. Continuous and stable spinal support is a core requirement for assisting rehabilitation. External support reduces the weight-bearing pressure on the spine, maintains its physiological curvature, and creates favorable conditions for tissue repair and functional recovery at the injury site. Currently, spinal injury patients often rely on braces for daily protection and support during the rehabilitation period. These devices have become a key link between clinical treatment and home rehabilitation, and their performance directly affects the patient's rehabilitation progress and quality of life. However, existing spinal injury support devices have several shortcomings that urgently need to be addressed. On the one hand, the support force of traditional devices is mostly fixed, making it impossible to flexibly adjust according to the patient's injury severity and rehabilitation stage. This makes it difficult to adapt to the treatment needs at different stages. In the early stages of injury, gentle support is needed to avoid secondary damage, while in the middle stages of rehabilitation, the support force needs to be gradually increased to promote functional recovery. Fixed support force often leads to insufficient adaptability. On the other hand, the support force stability of some adjustable devices is poor. As the patient's posture changes (such as switching between standing and sitting), the stress state of the support structure changes, easily causing fluctuations in support force. This makes it impossible to continuously provide balanced support to the spine, affecting the effectiveness of auxiliary treatment. Simultaneously, the wearing comfort and adaptability of existing devices are insufficient. Some devices directly compress the skin through rigid structures, resulting in poor breathability and causing discomfort such as stuffiness and itching with prolonged wear. Furthermore, the lack of flexible adjustment structures for patients of different body types makes it difficult to conform to individual body curves, further reducing the wearing experience and user compliance.

[0003] Furthermore, existing devices often focus solely on supporting the back spine, neglecting the need for coordinated protection of the cervical and spinal spines. Patients with spinal injuries often experience decreased cervical spine stability; without targeted support, this can easily lead to compensatory stress on the cervical spine, causing cervical strain or secondary injury, thus affecting overall rehabilitation outcomes. Simultaneously, traditional devices lack sufficient cushioning and protection; minor collisions during daily activities may fail to effectively absorb impact, potentially causing additional damage to the vulnerable spine. Therefore, developing an assistive device with stable and adjustable support, comfortable wear, and coordinated protection of both the spine and cervical spine has become an urgent need in the field of orthopedic spinal injury rehabilitation, and is of great significance for improving the effectiveness of adjuvant therapy and enhancing the patient's rehabilitation experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an auxiliary device for the treatment of orthopedic spinal injuries, which solves the problems of traditional spinal assistive devices such as unadjustable or unstable support force, poor wearability, lack of cervical spine protection, and insufficient comfort and cushioning, and is suitable for different rehabilitation stages and body types.

[0006] Preferably, the rear end of the side support plate is provided with first adjustment holes on both the upper and lower sides, and the interior of each first adjustment hole is threaded with a first locking bolt.

[0007] Preferably, elastic straps are fixedly installed on the upper and lower sides of the outer side end of one side of the side support plate, and strap through-hole brackets are fixedly installed on the upper and lower sides of the outer side end of the other side of the side support plate. Velcro is provided in the middle and at the end of the elastic straps.

[0008] Preferably, a short shaft is movably installed in the middle of the inner wall of the first chamber, and a support platform is movably installed inside the first chamber, with both ends of the support platform abutting against the surface of the spring plate. A threaded rod is fixedly installed on the outer end of each short shaft, and the outer diameter of the threaded rod is threadedly connected to the middle of the support platform on the corresponding side.

[0009] Preferably, an adjustment knob is movably installed at the center of the rear end of the upright frame, and a second chamber is opened in the center of the upright frame. The center of the second chamber extends into the interior of the second chamber through a rotating shaft and is fixedly installed with a driving bevel gear. The inner ends of the short shafts all extend into the interior of the second chamber and are fixedly installed with driven bevel gears. The inner ends of the driven bevel gears are all meshed with the outer side of the driving bevel gears.

[0010] Preferably, the middle of the inner end of the inflatable bag is connected by a connecting pipe, an inflation tube is fixedly installed on one side of the connecting pipe, and an elastic airbag is fixedly installed at the end of the inflation tube.

[0011] Preferably, an inflation port is fixedly installed at one end of the elastic airbag near the inflation tube, and an air inlet is fixedly installed at the other end of the elastic airbag away from the inflation tube. A one-way valve is fixedly installed inside both the inflation port and the air inlet, and a deflation valve is fixedly installed on one side of the outer diameter of the inflation tube.

[0012] Preferably, an extension rod is movably provided on the upper rear end of the support back plate, and a U-shaped mounting bracket is movably mounted on the top of the extension rod via a first coil spring, and a cervical spine support plate is movably mounted on the middle of the U-shaped mounting bracket via a second coil spring.

[0014] Preferably, the support back plate and the side support plate are provided with a number of ventilation holes in the middle.

[0015] This invention provides an auxiliary device for the treatment of orthopedic spinal injuries. It has the following beneficial effects: 1. This invention utilizes a linkage structure of a spinal support plate, connecting rods, rotating frame, and spring plate. The elastic force generated by the bending of the spring plate provides reverse support to the spine. At the same time, the relative sliding of the pressure rollers on the surface of the spring plate can compensate for changes in elastic force, ensuring that the elastic force of the spring plate remains stable. This allows the spinal support plate to provide continuous and balanced support to the back spine in different body postures such as standing and sitting, effectively assisting in the recovery after spinal injury and avoiding fluctuations in support force that could affect the treatment effect.

[0016] 2. This invention allows for precise adjustment of the spring plate's bending fulcrum by rotating an adjustment knob, thereby enabling multi-level adjustment of the spinal support force. Whether providing gentle support in the early stages of injury or enhanced support during recovery, the support can be flexibly adapted to the patient's treatment stage and physical sensations, significantly improving the targeted nature of adjuvant therapy.

[0017] 3. This invention inflates the air bag by cyclically squeezing the elastic air bladder. This not only allows for free adjustment of the tightness of the garment to fit the body curves of patients of different body types, avoiding excessive tightness or excessive looseness, but also utilizes the flexible structure of the air bag to provide collision cushioning, reducing secondary damage to the spine from accidental impacts during daily activities, thus balancing comfort and safety.

[0018] 4. The side support plates of the present invention can be adjusted laterally through the first adjustment hole and the first locking bolt, and the extension rod can be adjusted longitudinally through the second adjustment hole and the second locking bolt. Combined with the flexible fit of the air bag, patients of all heights and weights can find a suitable wearing position, greatly expanding the applicable population of the device.

[0021] The technical solutions in 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.

[0022] Example: Please see the appendix Figure 1 -Appendix Figure 7This invention provides an auxiliary device for the treatment of orthopedic spinal injuries, such as... Figure 1As shown, the device includes a support backplate 1, which serves as the core load-bearing structure of the entire device. It provides basic support to the user's back and its overall structural design conforms to the physiological curve of the human back, ensuring a good fit and providing a stable platform for the installation and functionality of subsequent components. Side support plates 2 are movably mounted on both sides of the rear end of the support backplate 1. These side support plates 2 can be adjusted according to the user's body shape and width to better fit the sides of the body, providing auxiliary fixation and lateral support to prevent the device from shifting left or right during wear. A stand 8 is fixedly installed in the middle of the rear end of the support backplate 1. The stand 8 provides a closed and stable installation space for the internal components, and its rigid structure ensures stability under stress. To ensure precise linkage of all transmission components and prevent deformation, rotating frames 9 are movably mounted on both the upper and lower ends of the upright frame 8. These rotating frames 9 can rotate around the upper and lower ends of the upright frame 8. As a key transmission component connecting the connecting rod 11 and the spring plate 14, they effectively transmit the force exerted on the spinal support plate 12 to the spring plate 14. Straight slots 10 are provided on both the upper and lower sides of the middle section of the support back plate 1. These slots provide reserved space for the movement of the connecting rod 11, ensuring smooth movement of the connecting rod 11 when driving the rotating frame 9 to rotate, avoiding jamming and ensuring the continuity of the transmission process. Connecting rods 11 are movably mounted on the front end of each rotating frame 9. These connecting rods 11 transmit force, accurately transmitting the thrust generated when the spinal support plate 12 moves backward to the rotating frame 9. The frame 9 drives the rotating frame 9 to rotate synchronously. The ends of the connecting rods 11 all pass through the interior of the corresponding straight slots 10 and extend to the front of the support back plate 1. This installation method ensures the freedom of movement of the connecting rods 11, and limits the movement trajectory of the connecting rods 11 through the straight slots 10 to prevent them from deviating from the preset movement direction. The ends of the connecting rods 11 are respectively fixedly installed on both sides of the rear end of the spinal support plate 12. The spinal support plate 12 directly contacts the user's back spine to bear the pressure of the back and transmit it to the connecting rods 11. At the same time, under the elastic force of the spring plate 14, it forms a stable support for the spine in the opposite direction, realizing the core function of auxiliary treatment. The upper and lower sides of the frame 8 are provided with first chambers 13. The first chamber 13 is the spring plate 14 and the support plate 1. The components, including number 8, provide independent installation and movement space to avoid interference between components and ensure the normal operation of their respective functions. Spring plates 14 are fixedly installed on both sides of the interior of the first chamber 13, with the ends of the spring plates 14 extending into the interior of the corresponding rotating frame 9. The spring plates 14 have good elastic deformation capabilities and can bend and generate elastic force when squeezed by the pressure rollers 15. This elastic force is transmitted in the opposite direction to the spinal support plate 12 through the rotating frame 9 and connecting rod 11, providing support for the spine. Simultaneously, its elastic characteristics can adapt to different stress conditions. Pressure rollers 15 are fixedly installed on one end of the inner wall of the rotating frame 9, with the rear ends of the pressure rollers 15 abutting against the surface of the corresponding spring plates 14. The pressure rollers 15 bend the spring plates 14 when the rotating frame 9 rotates.Furthermore, during the bending process, relative sliding occurs on the surface of the spring plate 14, causing the lever arm of the spring plate 14 to adjust according to the degree of bending, thereby compensating for changes in elastic force and ensuring that the elastic force remains stable. Inflatable bags 23 are fixedly installed on both sides of the front end of the support back plate 1. The inflatable bags 23 can be inflated to adjust the tightness of the garment, improving wearing comfort. Simultaneously, their flexible structure provides impact cushioning, reducing accidental impact damage to the spine and enhancing wearing safety. In this embodiment, the rear end of the side support plate 2 is provided with first adjustment holes 3 on both the upper and lower sides. The first adjustment holes 3 provide an adjustment path for the position adjustment of the side support plate 2, so that the side support plate 2 can be adjusted in the front-back or left-right directions along both sides of the support back plate 1. The first adjustment holes 3 are threaded with first locking bolts 4. The first locking bolts 4 are locked and fixed after the side support plate 2 is adjusted to a suitable position. The fastening force of the threaded connection ensures that the side support plate 2 will not shift during use, thus ensuring the stability of the lateral support. Furthermore, elastic straps 5 are fixedly installed on the upper and lower sides of the outer end of one side plate 2. The elastic straps 5 have a certain degree of elasticity and can adapt to the wearing needs of users of different body types. At the same time, their flexible material will not cause pressure damage to the skin. Strap perforation frames 6 are fixedly installed on the upper and lower sides of the outer end of the other side plate 2. Strap perforation frames 6 provide a channel for the elastic straps 5 to pass through, making it convenient for the ends of the elastic straps 5 to pass through and be fixed. Velcro 7 is provided in the middle and at the ends of the elastic straps 5. Velcro 7 achieves quick fixation of the elastic straps 5 by snapping together. The operation is convenient and the fixation effect is reliable, making it easy for users to put on and take off the device themselves. Furthermore, short shafts 16 are movably installed in the middle of the inner wall of the first chamber 13. The short shafts 16 can rotate around their own axis. As a key component for transmitting rotational power, they can transmit the rotational motion of the driven bevel gear 22 to the threaded rod 17. Support platforms 18 are movably installed inside the first chamber 13, and both ends of the support platforms 18 abut against the surface of the spring plate 14. The support platforms 18 are used to support the spring plate 14. The change in their position will change the bending fulcrum of the spring plate 14, thereby adjusting the magnitude of the elastic force generated when the spring plate 14 bends. Threaded rods 17 are fixedly installed on the outer ends of the short shafts 16, and the outer diameter of the threaded rods 17 is threaded to the middle of the corresponding side support platform 18. The threaded rods 17 rotate under the drive of the short shafts 16, and drive the support platforms 18 to move back and forth through the threaded transmission principle, so as to achieve precise adjustment of the position of the support platforms 18. Furthermore, an adjustment knob 19 is movably installed at the center of the rear end of the upright frame 8. The adjustment knob 19 provides a convenient operating component for the user; manual rotation drives the internal transmission structure to adjust the support force. A second chamber 20 is provided in the center of the upright frame 8. The second chamber 20 provides installation space for the driving bevel gear 21 and the driven bevel gear 22, ensuring smooth gear transmission and preventing interference from external impurities. The driving bevel gear 21 is fixedly installed in the center of the second chamber 20 via a rotating shaft. The driving bevel gear 21 serves as the power input gear. The adjustment knob 19... Driven by 9, it rotates and transmits power to the driven bevel gears 22 on both sides. The inner ends of the short shaft 16 extend into the interior of the second chamber 20 and are fixedly installed with driven bevel gears 22. The driven bevel gears 22 mesh with the driving bevel gears 21, which can transmit the rotational power of the driving bevel gears 21 to the short shaft 16, realizing the direction and transmission of power. The inner ends of the driven bevel gears 22 are meshed with the outer sides of the driving bevel gears 21. This meshing method ensures that when the driving bevel gears 21 rotate, they can simultaneously drive the driven bevel gears 22 on both sides to rotate synchronously in opposite directions, ensuring the synchronous movement of the support platforms 18 on both sides. Furthermore, the inner middle of the air bags 23 is connected by a connecting pipe 24, which enables gas exchange between the two air bags 23, ensuring that the two air bags 23 can expand synchronously during inflation, thus ensuring the consistency of the support and cushioning effect on both sides. An inflation pipe 25 is fixedly installed on one side of the connecting pipe 24, which provides a channel for gas delivery, delivering the air in the elastic airbag 26 to the connecting pipe 24. An elastic airbag 26 is fixedly installed at the end of the inflation pipe 25. The elastic airbag 26 serves as a power component for manual inflation, and through cyclic compression, it can achieve continuous air delivery, providing a convenient power source for inflating the air bags 23. Furthermore, an inflation port 27 is fixedly installed at one end of the elastic airbag 26 near the inflation tube 25. The inflation port 27 is used to deliver air from the elastic airbag 26 to the inflation tube 25. An air inlet 28 is fixedly installed at the other end of the elastic airbag 26 away from the inflation tube 25. The air inlet 28 is used to draw in outside air when the elastic airbag 26 is released, so as to realize the circulation and replenishment of air. One-way valves 29 are fixedly installed inside both the inflation port 27 and the air inlet 28. The one-way valves 29 ensure that air can only flow in a preset direction, avoid air backflow during inflation, and ensure efficient inflation. A deflation valve 30 is fixedly installed on one side of the outer diameter of the inflation tube 25. The deflation valve 30 is used to release air in the inflatable bag 23 when needed, so as to facilitate adjustment of the tightness of wearing or disassembly of the device. Furthermore, an extension rod 31 is movably provided on the upper rear end of the support back plate 1. The extension rod 31 can be adjusted up and down along the upper end of the support back plate 1 to adapt to the cervical spine position of users of different heights. A U-shaped mounting bracket 33 is movably installed on the top of the extension rod 31 via a first coil spring 32. The first coil spring 32 provides the U-shaped mounting bracket 33 with a left-right rotational reset force, so that the cervical spine support plate 35 can automatically reset after left-right rotation. The cervical spine support plate 35 is movably installed in the middle of the U-shaped mounting bracket 33 via a second coil spring 34. The second coil spring 34 provides the cervical spine support plate 35 with a front-back rotational reset force. At the same time, the cervical spine support plate 35 directly supports the user's cervical spine, playing a role in auxiliary support and protection of the cervical spine, and realizing the synergistic auxiliary treatment of the spine and cervical spine. Furthermore, a second adjustment hole 36 is provided on the lower inner side of the extension rod 31. The second adjustment hole 36 provides an adjustment path for the height adjustment of the extension rod 31, so that the extension rod 31 can be flexibly adjusted to suit different users. A second locking bolt 37 is threaded inside the second adjustment hole 36. The second locking bolt 37 is locked and fixed after the extension rod 31 is adjusted to a suitable height, ensuring that the extension rod 31 will not slide up and down during use, thus ensuring the support stability of the cervical spine support plate 35. Furthermore, the back plate 1 and the side support plate 2 are provided with several ventilation holes 38 in the middle. The ventilation holes 38 can enhance the air circulation when the device is worn, reduce the stuffiness and sweating caused by wearing it for a long time, reduce the risk of skin allergies or infections, and improve the comfort and acceptance of users wearing it for a long time.

[0023] Working principle: The user places the support backplate 1 against their back, passes the end of the elastic strap 5 through the corresponding strap perforation frame 6, and then uses the Velcro 7 at the end and middle to fasten it, completing the secure wearing of the device. The user then holds the elastic airbag 26 and cyclically compresses it. When the elastic airbag 26 is compressed, the one-way valve 29 in the inflation port 27 opens, allowing air from the elastic airbag 26 to enter the two air bags 23 through the inflation tube 25 and the connecting tube 24. Releasing the elastic airbag 26 opens the one-way valve 29 in the air inlet 28, allowing outside air to enter the elastic airbag 26. This cycle repeats, inflating the two air bags 23. By setting two air bags 23, not only can the tightness be adjusted after wearing to improve wearing comfort, but the air bags 23 can also provide impact cushioning to improve wearing safety. After wearing, the user's back will press backward against the spinal support plate 12. When the spinal support plate 12 moves backward, it will drive the rotating frame 9 to rotate through the connecting rod 11. When the rotating frame 9 rotates, it will bend the spring plate 14 through the pressure roller 15. The elastic force generated by the bent spring plate 14 will provide support to the spinal support plate 12 in the opposite direction, thereby supporting the user's back spine and achieving the purpose of auxiliary support therapy. At the same time, when the pressure roller 15 bends the spring plate 14, it will slide relative to its surface, causing the bent spring to... The lever arm of plate 14 also changes, which can compensate for the changing elastic force as the bending degree of spring plate 14 changes, so that the elastic force generated by spring plate 14 remains stable. This allows the spinal support plate 12 to maintain stable support for the user's back spine in different body postures. In addition, rotating the adjustment knob 19 can drive the driving bevel gear 21 to rotate. The driving bevel gear 21 will drive the driven bevel gears 22 on both sides and the short shaft 16 to rotate, thereby driving the threaded rods 17 on both sides to rotate. When the threaded rods 17 rotate, they will drive the two support platforms 18 to move inward or outward synchronously. When the position of the support platform 18 changes, the bending fulcrum of spring plate 14 will also change. The spring plate 14 changes its elasticity when it bends, thereby changing the support force of the spinal support plate 12 on the user's back spine. This allows for easy adjustment according to the needs of different stages of auxiliary treatment. The side support plates 2 on both sides can be adjusted in position through the first adjustment hole 3 and the first locking bolt 4. The extension rod 31 and the cervical support plate 35 can also be adjusted in position through the second adjustment hole 36 and the second locking bolt 37, making it convenient for users of different body types to use. The cervical support plate 35 is used to support the user's cervical spine and can rotate freely left and right and forward and backward. The first coil spring 32 and the second coil spring 34 provide auxiliary repositioning force to achieve auxiliary treatment of the user's cervical spine.
