Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically a rehabilitation assistive brace for spinal surgery. Background Technology

[0002] In the rehabilitation process after spinal surgery, assistive braces, as important adjunctive treatment tools, play a crucial role in protecting the surgical site, supporting the spine, limiting inappropriate movements, and promoting bone healing and muscle recovery.

[0003] However, a significant technical flaw exists in currently widely used post-operative rehabilitation braces for spinal surgery: the distance between the lumbar and thoracic regions is fixed. This design ignores the significant differences in upper body height among individual patients. Since each patient's height and body type are different, a fixed spacing often fails to meet the individualized needs of different patients. Specifically, for patients with longer upper bodies, a fixed spacing may result in insufficient support in the lumbar region, failing to effectively restrict spinal movement, and may even cause discomfort or compression symptoms due to excessive tightness. Conversely, for patients with shorter upper bodies, an excessively long brace may cause unnecessary compression in the thoracic region, affecting respiratory function and patient comfort. Furthermore, the fixed spacing design limits the flexibility and adaptability of the brace, making it difficult for doctors to select and adjust the brace according to the patient's specific situation. This not only increases the patient's financial burden but may also affect rehabilitation outcomes and prolong the rehabilitation period due to an ill-fitting brace.

[0004] Therefore, this application provides a rehabilitation assistive brace for spinal surgery to solve the above problems. Utility Model Content

[0005] This application provides a rehabilitation brace for spinal surgery, aiming to solve the problems mentioned in the background art, such as the existing auxiliary braces having a fixed distance between the lumbar and chest regions, which cannot adjust the distance between the lumbar and chest regions of the auxiliary brace according to the patient's height difference.

[0006] To achieve the above objectives, this application provides the following technical solution: a postoperative rehabilitation assistive brace for spinal surgery, comprising a lumbar back plate and an abdominal plate disposed on the front side of the lumbar back plate and connected to the lumbar back plate for securing to the patient's abdominal region; further comprising a thoracic back plate disposed above the lumbar back plate and a thoracic plate disposed on the front side of the thoracic back plate and connected to the thoracic back plate for securing to the patient's chest; the design of the abdominal plate and the thoracic plate increases the contact area between the brace and the patient's body, effectively preventing the brace from sliding or shifting during the patient's activities, and improving the stability of the brace.

[0007] To accommodate different patient groups, the distance between the lumbar and thoracic back panels is designed to accommodate varying patient heights. Adjustment structures are provided on both sides of the lumbar and thoracic back panels to adjust this distance. These structures include a worm gear assembly fixedly mounted on the lumbar back panel, a threaded sleeve fixedly mounted on the thoracic back panel, and a drive screw inserted into the bottom of the threaded sleeve and fixedly connected to the worm gear shaft of the worm gear assembly. A perforated plate is fixedly connected to the end of the worm shaft of the worm gear assembly. When the brace needs adjustment to accommodate different patient heights, rotating the perforated plate rotates the worm shaft of the worm gear assembly. Since the worm shaft is fixedly connected to the drive screw, the rotation of the worm shaft causes the drive screw to move up and down within the threaded sleeve. Because the drive screw is connected to the lumbar and thoracic back plates via a worm gear combination and a threaded sleeve, the up-and-down movement of the drive screw causes the thoracic back plate to move up and down relative to the lumbar and thoracic back plates, thus adjusting the distance between them. After adjustment, the brace fits snugly against the patient's body, providing stable support and a comfortable wearing experience.

[0008] Preferably, to ensure that the lumbar support plate and the chest support plate are in the same plane, a plurality of guide mechanisms are provided on the rear side between the lumbar support plate and the chest support plate. Each guide mechanism includes a guide sleeve fixedly inserted into the top of the lumbar support plate and a guide rod inserted into the top of the guide sleeve and fixedly connected to the bottom of the chest support plate. The introduction of the guide mechanisms effectively limits the lateral movement of the chest support plate during adjustment, ensuring that it remains in the same plane as the lumbar support plate, thereby enhancing the overall stability of the brace. Through the precise guiding action of the guide mechanisms, the adjustment of the chest support plate becomes more accurate, further improving the fit between the brace and the patient's body and providing more precise support for the patient.

[0009] Preferably, to improve the comfort of the lumbar support plate for the patient, the top and bottom of both sides of the lumbar support plate are provided with a first arc-shaped groove and a second arc-shaped groove to adapt to the sides of the patient's waist. The design of the first and second arc-shaped grooves allows the lumbar support plate to better conform to the natural curve of the patient's waist, reducing friction and pressure between the brace and the skin of the waist, thereby significantly improving the patient's comfort. By reducing pressure on the lumbar region, the first and second arc-shaped grooves also help promote blood circulation in the waist, aiding postoperative recovery and reducing discomfort.

[0010] Preferably, in order to improve the compatibility between the abdominal plate and the back plate: the top and bottom of both ends of the abdominal plate are machined with a first arc-shaped chamfer that is compatible with the first arc-shaped groove and the second arc-shaped groove.

[0011] Preferably, to prevent the abdominal plate from compressing the patient's abdomen, the abdominal plate has a first elliptical groove for fitting the patient's abdomen. The design of the first elliptical groove effectively reduces direct pressure from the abdominal plate on the patient's abdomen, making the patient feel more relaxed and comfortable when wearing the brace. The elliptical groove design can better adapt to the abdominal shape of different patients, allowing both thin and overweight patients to find a suitable wearing position, improving the brace's versatility and adaptability.

[0012] Preferably, to improve the comfort of the chest and back panel for the patient, the top of both sides of the chest and back panel are provided with a third arc-shaped groove for fitting the patient's armpit. The design of the third arc-shaped groove effectively reduces the direct pressure of the chest and back panel on the patient's armpit, avoiding pain or discomfort caused by prolonged wear, and improving the patient's comfort.

[0013] Preferably, in order to improve the compatibility between the breast plate and the back plate, the top of both ends of the breast plate are machined with a second arc-shaped chamfer that matches the third arc-shaped groove.

[0014] Preferably, to prevent the chest plate from compressing the patient's chest, the chest plate is provided with a second elliptical groove for fitting the patient's chest. The design of the second elliptical groove effectively reduces the direct compression of the chest plate on the patient's chest, making the patient feel more relaxed and comfortable when wearing the brace, and helping to reduce pain and discomfort during the postoperative recovery process.

[0015] Preferably, to facilitate the fixing of the lumbar and abdominal panels, as well as the chest and back panels, the lumbar and chest panels are fixedly connected to both sides with hook and loop fasteners, and the abdominal and chest panels are fixedly connected to both sides with hook and loop fasteners that connect to the hook and loop fasteners. The hook and loop fastener design makes the assembly of the lumbar and abdominal panels, chest and back panels, and chest panels very simple and quick. Users only need to glue the corresponding hook and loop fasteners together; no complicated fixing devices or tools are required.

[0016] Preferably, to facilitate airflow between the lumbar and thoracic back panels and the patient's back, several ventilation holes are provided on both the lumbar and thoracic back panels. This design allows air to circulate freely between the brace and the patient's back, effectively reducing temperature and humidity in the back area, minimizing stuffiness and sweat buildup, and improving patient comfort. Good breathability also helps reduce skin dampness, itching, or inflammation caused by prolonged brace use, protecting the patient's skin health.

[0017] This application utilizes an adjustable structure design to flexibly adjust the distance between the lumbar and thoracic back plates according to the patient's upper body height, ensuring a close fit between the brace and the patient's body, improving adaptability and comfort. Reasonable support and restriction of range of motion aid in bone healing and muscle recovery for patients after spinal surgery, shortening the rehabilitation period. The adjustable structure employs a worm gear combination that creates a self-locking mechanism; the distance can be adjusted simply by rotating the pivot plate, making operation quick and easy.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Example

[0025] This embodiment provides a rehabilitation assistive brace for spinal surgery, such as... Figure 1-4As shown, the brace includes a lumbar support plate 1 and an abdominal plate 2 located in front of and connected to the lumbar support plate 1 for securing it to the patient's abdominal region; it also includes a thoracic support plate 3 located above the lumbar support plate 1 and a chest plate 4 located in front of and connected to the thoracic support plate 3 for securing it to the patient's chest; wherein, the lumbar support plate 1, as the basic support part of the brace, is located in the patient's lumbar region, providing stable support. The abdominal plate 2 is used to secure it to the patient's abdominal region, increasing the stability and comfort of the brace. The thoracic support plate 3, located above the lumbar support plate 1, provides support to the patient's chest region, helping to limit excessive spinal movement. The chest plate 4 is used to secure it to the patient's chest, further ensuring the stability and adaptability of the brace. The design of the abdominal plate 2 and the chest plate 4 increases the contact area between the brace and the patient's body, effectively preventing the brace from sliding or shifting during the patient's activities, and improving the stability of the brace.

[0026] To accommodate different patient groups, the distance between the lumbar support plate 1 and the thoracic support plate 3 is adjusted on both sides of the lumbar support plate 1 and the thoracic support plate 3 using adjustment structures 5. Each adjustment structure 5 includes a worm gear assembly 51 fixedly mounted on the lumbar support plate 1, a threaded sleeve 52 fixedly mounted on the thoracic support plate 3, and a drive screw 53 inserted into the bottom of the threaded sleeve 52 and fixedly connected to the worm gear shaft on the worm gear assembly 51. A perforated plate 511 is fixedly connected to the end of the worm shaft of the worm gear assembly 51. Through the adjustment structure 5, the distance between the lumbar support plate 1 and the thoracic support plate 3 can be flexibly adjusted according to the patient's upper body height, ensuring a close fit between the brace and the patient's body, improving fit and comfort. Appropriate support and restriction of range of motion help bone healing and muscle recovery in patients after spinal surgery, shortening the rehabilitation period. The adjustment structure 5 uses a worm gear assembly 51 that forms a self-locking mechanism; the distance can be adjusted by rotating the perforated plate 511, making operation simple and quick. When the brace needs to be adjusted to accommodate different patients' upper body heights, the worm shaft of the worm gear assembly 51 is rotated by rotating the worm plate 511. Since the worm shaft is fixedly connected to the drive screw 53, the rotation of the worm shaft causes the drive screw 53 to move up and down within the threaded sleeve 52. Because the drive screw 53 is connected to the lumbar support plate 1 and the chest support plate 3 respectively via the worm gear assembly 51 and the threaded sleeve 52, the up-and-down movement of the drive screw 53 causes the chest support plate 3 to move up and down relative to the lumbar support plate 1, thereby adjusting the distance between the lumbar support plate 1 and the chest support plate 3. After adjustment, the brace fits snugly against the patient's body, providing stable support and a comfortable wearing experience.

[0027] Furthermore, to ensure that the lumbar support plate 1 and the chest support plate 3 are in the same plane, several guide mechanisms 6 are provided on the rear side between the lumbar support plate 1 and the chest support plate 3. Each guide mechanism 6 includes a guide sleeve 61 fixedly inserted into the top of the lumbar support plate 1 and a guide rod 62 inserted into the top of the guide sleeve 61 and fixedly connected to the bottom of the chest support plate 3. The introduction of the guide mechanism 6 effectively restricts the lateral movement of the chest support plate 3 during adjustment, ensuring that it remains in the same plane as the lumbar support plate 1, thereby enhancing the overall stability of the brace. Through the precise guiding action of the guide mechanism 6, the adjustment of the chest support plate 3 becomes more accurate, further improving the fit between the brace and the patient's body and providing more precise support for the patient. When the distance between the lumbar support plate 1 and the chest support plate 3 is adjusted by the adjustment structure 5, the guide mechanism 6 begins to function. Specifically, as the drive screw 53 moves up and down within the threaded sleeve 52, the chest support plate 3 begins to adjust up and down relative to the lumbar support plate 1. At this time, the guide rod 62 slides within the guide sleeve 61, providing a stable guide path for the up-and-down movement of the chest and back plate 3. Since the guide sleeve 61 is fixedly connected to the lumbar and back plate 1, and the guide rod 62 is fixedly connected to the chest and back plate 3, this sliding ensures that the chest and back plate 3 remains in the same plane as the lumbar and back plate 1 during adjustment. This not only achieves flexible adjustment of the spacing but also ensures the overall stability and fitting accuracy of the brace.

[0028] Specifically, to improve the comfort of the lumbar support plate 1 for the patient, the top and bottom of both sides of the lumbar support plate 1 are provided with a first arc-shaped groove 11 and a second arc-shaped groove 12 to adapt to the patient's lower back. The shape and curvature of the first arc-shaped groove 11 are designed according to the natural curve of the upper part of the human waist, aiming to provide a more fitting support for the upper part of the patient's waist and reduce the pressure caused by prolonged wear. The second arc-shaped groove 12 echoes the first arc-shaped groove 11, and its design is also based on the natural curve of the lower part of the human waist, ensuring that the brace also provides comfortable support below the waist, while promoting air circulation and reducing stuffiness. The design of the first arc-shaped groove 11 and the second arc-shaped groove 12 allows the lumbar support plate 1 to better conform to the natural curve of the patient's waist, reducing friction and pressure between the brace and the skin of the waist, thereby significantly improving the patient's wearing comfort. By reducing pressure in the lumbar region, the first arc-shaped groove 11 and the second arc-shaped groove 12 also help promote blood circulation in the waist, aiding postoperative recovery and reducing discomfort. The curved groove design increases the gap between the brace and the skin, facilitating air circulation, reducing stuffiness caused by prolonged wear, and keeping the lumbar region dry. When patients wear the post-spinal surgery rehabilitation brace, the lumbar support plate 1 fits snugly against their lower back. Due to the presence of the first curved groove 11 and the second curved groove 12, the lumbar support plate 1 automatically adapts to the natural curves of the patient's lower back, forming a more closely fitting support surface. This fit not only reduces direct pressure from the brace on the lumbar skin but also improves wearing comfort by increasing the contact area and reducing contact pressure. Simultaneously, the curved groove design promotes air circulation, reducing stuffiness caused by prolonged wear and providing a more comfortable rehabilitation environment for patients.

[0029] More specifically, in order to improve the compatibility between the abdominal plate 2 and the back plate 1: the top and bottom of both ends of the abdominal plate 2 are machined with a first arc-shaped chamfer that is compatible with the first arc-shaped groove 11 and the second arc-shaped groove 12.

[0030] Furthermore, to prevent the abdominal plate 2 from compressing the patient's abdomen, the abdominal plate 2 has a first elliptical groove 21 designed to fit the patient's abdomen. The first elliptical groove 21 is located at the center or an appropriate position of the abdominal plate 2, and its shape and size are designed according to the average size and shape of the human abdomen to ensure a good fit to the patient's abdominal area. The first elliptical groove 21 provides sufficient space for the patient's abdomen, avoiding the pressure and discomfort caused by an overly tight brace. The design of the first elliptical groove 21 effectively reduces direct pressure from the abdominal plate 2 on the patient's abdomen, making the patient feel more relaxed and comfortable when wearing the brace. The elliptical groove design better adapts to the abdominal shape of different patients, allowing both thin and overweight patients to find a suitable wearing position, improving the versatility and adaptability of the brace. By reducing pressure on the patient's abdomen, the first elliptical groove 21 also helps promote blood circulation and lymphatic drainage in the area, aiding postoperative recovery and reducing discomfort. When the patient wears the spinal surgery postoperative rehabilitation brace, the abdominal plate 2 will fit snugly against the patient's abdominal area. Because of the presence of the first elliptical groove 21, the patient's abdomen can naturally fit into the groove, avoiding the feeling of compression caused by the brace being too tight. At the same time, the design of the elliptical groove also allows the abdominal plate 2 to provide some space for the patient's abdomen to move while maintaining its supporting function, so that the patient can maintain natural breathing and posture when wearing the brace, thereby improving the comfort of wearing and the rehabilitation effect.

[0031] Specifically, to improve the comfort of the chest back plate 3 for the patient, the top of both sides of the chest back plate 3 is provided with a third arc-shaped groove 31 for fitting the patient's armpit. The third arc-shaped groove 31, located on the top of both sides of the chest back plate 3, is carefully designed in shape and curvature according to the natural shape of the human armpit. This design aims to provide sufficient space for the patient's armpit area, avoiding discomfort caused by friction or pressure between the edge of the brace and the patient's armpit when wearing the brace. The third arc-shaped groove 31 allows the chest back plate 3 to better conform to the natural curve of the patient's chest, while reducing interference with the armpit area and improving wearing comfort. The design of the third arc-shaped groove 31 effectively reduces direct pressure from the chest back plate 3 on the patient's armpit, avoiding pain or discomfort caused by prolonged wear, thus improving patient comfort. By providing sufficient space for the armpit area, the third arc-shaped groove 31 allows the patient to feel more relaxed and comfortable when wearing the brace, thereby improving the overall wearing experience. When a patient wears a post-spinal surgery rehabilitation brace, the thoracic back plate 3 fits snugly against the patient's chest area. Due to the presence of the third arc-shaped groove 31, the patient's armpit can naturally rest within or near the groove, avoiding direct contact and pressure between the edge of the thoracic back plate 3 and the patient's armpit. This design allows the thoracic back plate 3 to maintain its supporting function while minimizing interference with the patient's armpit area, thereby improving wearing comfort and rehabilitation effectiveness. Furthermore, the third arc-shaped groove 31 allows the thoracic back plate 3 to better adapt to the different body shapes of various patients, improving the brace's applicability and versatility.

[0032] More specifically, in order to improve the compatibility between the breast plate 4 and the back plate 3: the top of both ends of the breast plate 4 are machined with a second arc-shaped chamfer that matches the third arc-shaped groove 31.

[0033] Furthermore, to prevent the chest plate 4 from compressing the patient's chest, a second elliptical groove 41 is provided on the chest plate 4 to fit the patient's chest. The second elliptical groove 41 is located at the center or an appropriate position of the chest plate 4, and its shape and size are designed according to the average size and shape of the human chest to ensure a good fit to the patient's chest area. The second elliptical groove 41 provides sufficient space for the patient's chest, avoiding the pressure and discomfort caused by an overly tight brace. At the same time, the design of this groove also takes into account the respiratory movements of the chest, ensuring that normal breathing is not restricted when wearing the brace. The design of the second elliptical groove 41 effectively reduces the direct compression of the chest plate 4 on the patient's chest, making the patient feel more relaxed and comfortable when wearing the brace, helping to reduce pain and discomfort during postoperative recovery. By providing sufficient space for the chest, the second elliptical groove 41 also ensures that the patient can maintain smooth breathing when wearing the brace, avoiding chest tightness and discomfort caused by the brace restricting breathing. The elliptical groove design better adapts to different chest shapes, allowing patients with both flat and full chests to find a suitable wearing position, thus improving the brace's versatility and fit. When a patient wears the post-spinal surgery rehabilitation brace, the chest plate 4 fits snugly against the patient's chest area. Due to the presence of the second elliptical groove 41, the patient's chest can naturally embed itself within the groove, avoiding the feeling of compression caused by an overly tight brace. This design allows the chest plate 4 to provide some space for the patient's chest to move while maintaining its support function, ensuring smooth and comfortable breathing. Furthermore, the second elliptical groove 41 allows the chest plate 4 to better conform to the patient's chest curve during wear, reducing discomfort caused by friction or pressure, thereby improving the overall wearing experience and rehabilitation effect.

[0034] Specifically, to facilitate the fixation of the lumbar support plate 1 and abdominal plate 2, as well as the thoracic support plate 3 and chest plate 4: both sides of the lumbar support plate 1 and thoracic support plate 3 are fixedly connected with Velcro loops 7, and both sides of the abdominal plate 2 and chest plate 4 are fixedly connected with Velcro hooks 71 connected to the loops 7. The Velcro design makes the assembly of the lumbar support plate 1, abdominal plate 2, thoracic support plate 3, and chest plate 4 very simple and quick. Users only need to glue the corresponding Velcro loops together; no complicated fixing devices or tools are required. Due to the flexibility of the Velcro connection, users can easily adjust the tightness between the components according to their own needs to achieve the best wearing effect. When wearing the post-spinal surgery rehabilitation brace, the user first needs to place the lumbar support plate 1 and thoracic support plate 3 in the appropriate position, ensuring they conform to the patient's body contour. Then, the user can align the abdominal plate 2 and chest plate 4 with the lower and upper sides of the lumbar support plate 1 and thoracic support plate 3, respectively, and firmly glue the Velcro hooks 71 on both sides to the corresponding Velcro loops 7. A simple pressing operation completes the secure connection between the components. When it is necessary to adjust the tightness or remove the brace, the user can simply peel off the Velcro connection, which is convenient and quick.

[0035] Specifically, to facilitate airflow between the lumbar support plate 1 and the thoracic support plate 3 and the patient's back, several ventilation holes 8 are provided on both the lumbar support plate 1 and the thoracic support plate 3. The design of the ventilation holes 8 allows air to circulate freely between the brace and the patient's back, effectively reducing the temperature and humidity in the back area, minimizing stuffiness and sweat buildup, and improving patient comfort. Good breathability helps reduce skin dampness, itching, or inflammation caused by prolonged brace wear, protecting the patient's skin health. By promoting airflow, the ventilation holes 8 also help keep the patient's back dry and clean, providing a more favorable environment for postoperative wound healing and recovery. When the patient wears the spinal surgery postoperative rehabilitation brace, the ventilation holes 8 on the lumbar support plate 1 and the thoracic support plate 3 begin to function. With the patient's breathing and movement, outside air enters the small space between the brace and the patient's back through the ventilation holes 8 and exchanges with the internal air. This continuous airflow not only reduces the temperature and humidity in the back area but also reduces sweat buildup on the skin surface, thus keeping the back dry and comfortable.
