Description

Technical Field

[0001] This invention relates to the field of medical bracing technology, and in particular to a progressively adjustable dynamic traction brace for postoperative rehabilitation of spastic clubfoot. Background Technology

[0002] Postoperative rehabilitation traction braces for clubfoot are key tools for preventing recurrence of deformity and maintaining the corrective effect of surgery. They mainly use continuous and gentle external force to fix the foot in abduction and dorsiflexion, helping the Achilles tendon and plantar fascia adapt to the new physiological position and preventing re-contraction. They are usually put into use immediately after the cast is removed. Initially, they need to be worn all day for 23-24 hours a day for about 3 months. Then, they are worn at night and during naps for no less than 12 hours a day, generally continuing until 4-6 years of age. Some children need to wear them until puberty.

[0003] In the rehabilitation of children with lower limb deformities such as clubfoot, existing orthotic braces generally suffer from rigid structures, difficulty in adjustment, and limited fixation methods. The spacing between the plantar plates is mostly fixed and cannot be dynamically adjusted with the rehabilitation stage, which can easily lead to correction failure or joint discomfort. Fixation often relies on a single strap or Velcro, lacking segmented independent adjustment, which can easily cause local pressure and is cumbersome to wear. In emergencies, the straps need to be untied or cut one by one to remove the brace. If the child experiences significant discomfort, the emergency response is slow and it is impossible to quickly remove the brace completely in an emergency. Traction adjustment mostly relies on external assistive devices, making it difficult to achieve precise and continuous staged control. There is also a lack of effective intervention for postoperative muscle tension and blood circulation problems. Traditional external heat therapy has defects such as uneven temperature and easy displacement. Therefore, this application provides a progressively adjustable ankle joint dynamic traction brace for the rehabilitation of spastic clubfoot to meet the needs. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a progressively adjustable dynamic traction brace for postoperative rehabilitation of spastic clubfoot. It solves the problems of existing braces, such as the inability to quickly adjust the distance between the soles of the feet, the single fixation method, the difficulty in quick release in emergency situations, the inability to continuously adjust the traction force, and the lack of heat-assisted function, which lead to poor orthopedic fit, low comfort, slow emergency response, and limited rehabilitation effects.

[0016] Preferably, the upper surface of the base plate sleeve rod is provided with a sleeve rod thread groove, the surface of the locking component is provided with a locking thread, the internal thread of the sleeve rod thread groove passes through the locking component, the inner bottom of the sleeve rod thread groove is provided with a sleeve rod hole, one side of the base plate sleeve rod is provided with a sleeve rod sliding groove, one side of the extension rod is provided with an extension fixing rod, the extension fixing rod is slidably connected inside the sleeve rod sliding groove, and the upper surface of the extension fixing rod is provided with an extension fixing hole.

[0017] Preferably, the surfaces of the left foot brace and the left leg brace are each provided with a left fixing component, and the number of the left fixing components is three; the surfaces of the right foot brace and the right leg brace are each provided with a right fixing component, and the number of the right fixing components is three.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above solution, the left and right foot soles are connected by a base plate sleeve and an extension rod. To adjust the distance, first rotate the mis-touch sleeve to remove it from the mis-touch threaded seat, then pull the locking head upward to disengage the locking rod from the extension fixing hole of the extension rod. At the same time, stretch the locking spring and rotate the locking head to the upper surface of the locking seat for temporary placement. Then, pull the base plate sleeve and the extension rod to adjust the distance between the two foot soles. After adjustment, rotate the locking head. Under the action of the locking spring, the locking rod is reinserted into the corresponding extension fixing hole, and the locking head is embedded in the locking groove. This ensures that the extension rod does not retract or wobble during walking or activity, allowing for quick and precise adjustment of the distance. This adapts to different rehabilitation stages after surgery and reduces the risk of correction failure or joint discomfort due to improper distance.

[0020] The procedure involves placing the left foot into the left foot brace and the lower leg into the left leg brace, then inserting the left fixation buckle into the left fixation seat for initial fixation. The three left fixation components are then adjusted sequentially, along with the tightness of the left fixation straps. The left fixation hook and the left fixation felt are then fastened together. The same procedure is performed on the right foot, achieving comprehensive and segmented stable fixation of the foot and lower leg. This effectively prevents foot eversion or inversion, reduces local pressure, and improves orthopedic stability and comfort. When the child cries, experiences skin redness or pain, the operator can quickly press the release buttons on both left and right fixation buckles simultaneously, causing all six fixation straps to loosen synchronously. The feet are removed from the brace within seconds, eliminating the need to individually unfasten Velcro or cut the straps, significantly shortening emergency treatment time and preventing skin ischemia, pressure sores, or joint damage caused by prolonged restraint. All buckles are located in easily accessible positions, facilitating efficient operation by parents or medical staff and significantly improving safety during the child's rehabilitation process.

[0021] Elastic bands are placed on the left and right feet respectively. By rotating the left and right traction handles clockwise, the corresponding rotating nuts move upward along the traction thread, shortening the traction rod and traction spring, tightening the connecting rope, thereby raising the position of the elastic bands and applying greater upward traction. In the early postoperative period, a smaller traction force is used, which is gradually increased in the middle period, and stable traction is maintained in the later period to promote Achilles tendon lengthening and recovery of foot dorsiflexion function. This allows for continuous, reversible, and precise adjustment of the traction force. The left heating pad is fixed to the left leg brace by its hook surface on the left leg, and the right heating pad is fixed to the right leg brace in the same way. After being powered on, the heat is evenly transferred to the calf muscles and joint area, relieving postoperative muscle tension, improving blood circulation, and promoting tissue repair. The heating pads can be quickly installed and removed, avoiding the problems of displacement or uneven temperature of traditional hot compresses. This effectively reduces pain, prevents muscle atrophy, and significantly improves the comfort and treatment compliance of children.

[0022] In summary, this invention features a locking mechanism that uses a base plate sleeve rod and an extension rod to quickly and accurately adjust the distance between the left and right foot plates, adapting to different postoperative rehabilitation stages. The three-part segmented fixation components, combined with buckles and Velcro, provide comprehensive and stable fixation of the foot and lower leg, effectively preventing eversion and inversion, reducing pressure, and improving comfort. A synchronized release button allows for the loosening of six straps within seconds, facilitating emergency treatment and reducing pressure sores or joint damage. A rotating traction handle provides stepless adjustment of the elastic band tension, enabling continuous, reversible, and precise Achilles tendon traction, promoting dorsiflexion recovery. A detachable heating pad, secured with Velcro, provides even heat to the lower leg, relieving muscle tension, improving circulation, and preventing atrophy. These advantages significantly improve patient comfort and treatment compliance, making it particularly suitable for postoperative rehabilitation of children's feet and ankles.

[0048] like Figures 1 to 7As shown, an embodiment of the present invention provides a progressively adjustable dynamic traction brace for postoperative rehabilitation of spastic clubfoot, comprising a left foot plate 1, a left foot plate cover 2 on the upper surface of the left foot plate 1, a foot plate sleeve 3 on one side of the left foot plate 1, an accidental contact threaded seat 301 on the upper surface of the foot plate sleeve 3, an accidental contact sleeve 302 threaded through the surface of the accidental contact threaded seat 301, an extension rod 4 slidably connected inside the foot plate sleeve 3, a right foot plate 5 installed on one side of the extension rod 4, a left control groove 101, a left battery groove 102, a left temperature and humidity groove 103 and a left wire passage hole 104 sequentially formed on the upper surface of the left foot plate 1 from front to back, and a right control groove 501, a right battery groove 502, a right temperature and humidity groove 503 and a right wire passage hole 504 sequentially formed on the upper surface of the right foot plate 5 from front to back, a right foot plate cover 6 on the upper surface of the right foot plate 5, and a foot plate sleeve 3. The upper surface of the base plate sleeve rod 3 is threaded through by a locking component 7. The locking component 7 includes a locking seat 701, a locking rod 702, a locking head 703, a locking spring 704, and a locking groove 705. The locking rod 702 is slidably connected inside the locking seat 701. The locking head 703 is installed on the upper surface of the locking rod 702. The locking spring 704 is provided on the surface of the locking rod 702. The upper part of the surface of the locking seat 701 is provided with a locking groove 705. The upper surface of the base plate sleeve rod 3 is provided with a sleeve thread groove. The surface of the locking component 7 is provided with a locking thread. The locking component 7 is threaded through the inner thread of the sleeve thread groove. A sleeve hole is provided at the bottom of the sleeve thread groove. A sleeve sliding groove is provided on one side of the base plate sleeve rod 3. An extension fixing rod 401 is installed on one side of the extension rod 4. The extension fixing rod 401 is slidably connected inside the sleeve sliding groove. An extension fixing hole is provided on the upper surface of the extension fixing rod 401.

[0049] The left foot base plate 1 and right foot base plate 5 are connected by the base plate sleeve rod 3 and the extension rod 4. The accidental contact sleeve 302 is removed from the accidental contact threaded seat 301 by rotating the accidental contact sleeve 302. The locking rod 702 is pulled out of the extension fixing hole of the extension fixing rod 401 by pulling out the locking head 703. The locking spring 704 is stretched by pulling out the locking spring 704 to generate elastic force, so that the locking head 703 is pulled out to the upper part of the locking groove 705. The locking head 703 is placed on the upper surface of the locking seat 701 for temporary placement by rotating the base plate sleeve rod 3. The rod 3 and extension rod 4 adjust the distance between the left foot plate 1 and the right foot plate 5. After adjustment, the locking head 703 is rotated to allow the locking rod 702 to be inserted into the extension fixing hole of the corresponding extension fixing rod 401 through the elastic force of the locking spring 704, and the locking head 703 to enter the locking groove 705 for fixation. This ensures that the extension rod 4 will not retract or shake due to walking or activity, thus enabling the structure to quickly adjust the distance between the left foot plate 1 and the right foot plate 5. This allows the brace to accurately correspond to different rehabilitation stages after surgery, reducing the risk of correction failure or joint discomfort due to improper spacing.

[0050] By opening the left foot plate 1 and the right foot plate 5, and the left and right foot plate covers 2 and 6 respectively, and through the left control slot 101, left battery slot 102, left temperature and humidity slot 103 and left wiring hole 104 on the left foot plate 1, and the right control slot 501, right battery slot 502, right temperature and humidity slot 503 and right wiring hole 504 respectively on the right foot plate 5, control chip modules can be placed in the left control slot 101 and right control slot 501 respectively, batteries can be placed in the left battery slot 102 and right battery slot 502 respectively, temperature and humidity sensors can be placed in the left temperature and humidity slot 103 and right temperature and humidity slot 503 respectively, and wires can be placed and connected through the left and right wiring holes 104 and right wiring holes 504. This achieves modular installation of key components such as control units, power supplies, and sensors, meeting the needs for real-time monitoring and temperature feedback at different stages after clubfoot surgery.

[0051] like Figures 8 to 11 As shown, in this embodiment, the upper surface of the left foot plate 1 is provided with a left foot brace 8, the upper surface of the left foot brace 8 is provided with a left leg brace 9, the upper surface of the left leg brace 9 is equipped with a left fixing plate 10, and the surface of the left leg brace 9 is provided with a left fixing assembly 11. The left fixing assembly 11 includes a left fixing strap 111, a left fixing buckle 112, a left fixing seat 113, a left fixing felt surface 114, a left fixing hook surface 115, and a left fixing seat 116. One end of the left fixing strap 111 is equipped with a left fixing... The left fixing buckle 112 has a left fixing seat 113 attached to its surface. The left fixing strap 111 has a left fixing felt surface 114 and a left fixing hook surface 115 arranged sequentially from front to back. The left fixing strap 111 has a left fixing seat 116. The left fixing felt surface 114 and the left fixing hook surface 115 are Velcro. The left fixing plate 10 has a left placement compartment 12. The upper surface of the right foot plate 5 has a right foot brace 13. The upper surface of the right foot brace 13 has a right leg brace 14. A right fixing plate 15 is installed on the upper surface of the right leg brace 14. A right fixing assembly 16 is provided on the surface of the right leg brace 14. The right fixing assembly 16 includes a right fixing strap 161, a right fixing buckle 162, a right fixing seat 163, a right fixing felt surface 164, a right fixing hook surface 165, and a right fixing base 166. A right fixing buckle 162 is installed at one end of the right fixing strap 161. The right fixing seat 163 is engaged with the surface of the right fixing buckle 162. The surface of the right fixing strap 161 extends from front to back. The right fixing surface 164 and the right fixing hook surface 165 are arranged in sequence. The surface of the right fixing strap 161 is provided with a right fixing seat 166. The right fixing surface 164 and the right fixing hook surface 165 are Velcro. The surface of the right fixing plate 15 is provided with a right placement compartment 17. The surfaces of the left foot brace 8 and the left leg brace 9 are both provided with left fixing components 11. There are three left fixing components 11. The surfaces of the right foot brace 13 and the right leg brace 14 are both provided with right fixing components 16. There are three right fixing components 16.

[0052] When putting the brace on the child, the child's left foot is placed in the left foot brace 8, and the lower leg is fitted into the left leg brace 9. Initial fixation is achieved by inserting the left fixation buckle 112 into the left fixation seat 113. The other two left fixation components 11 are then adjusted and fixed to the lower leg and left foot respectively for initial fixation. After this initial fixation, the tension of the left fixation strap 111 is adjusted by pulling or loosening one end of the left fixation hook 115 on the left fixation strap 111. After adjustment, the left fixation hook 115 at one end of the left fixation strap 111 is glued to the left fixation felt 114 at the other end of the left fixation strap 111. The other two left fixation components 11 are then adjusted and fixed. Finally, when putting the brace on the child, the child's right foot is placed in the right foot brace 13, and the lower leg is fitted into the right leg brace 14. Initial fixation is achieved by inserting the right fixation buckle 162 into the right fixation seat 163. The other two right fixation components 16 are then adjusted and fixed to the lower leg and right foot respectively for initial fixation. After the initial fixation is completed, the right fixation hook 165 on the right fixation strap 161 is pulled or loosened to adjust the tightness of the right fixation strap 161 on the child's right foot or lower leg. After adjustment, the right fixation hook 165 at one end of the right fixation strap 161 is glued to the right fixation felt 164 at the other end of the right fixation strap 161. The other two right fixation components 16 are adjusted and fixed in sequence, thereby achieving all-round, segmented stable fixation of the child's foot and lower leg. This effectively prevents abnormal movements such as foot eversion and inversion, reduces local pressure caused by a single strap, and significantly improves the orthopedic stability and wearing comfort of the brace.

[0053] When a child experiences significant discomfort during use, such as crying, skin redness, or pain, the brace must be immediately released. Simultaneously, personnel must press the release buttons on the left and right fixation buckles 112 and 162, instantly separating the left fixation buckles 112 and left fixation seats 113 on the three left fixation straps 111, and the right fixation buckles 162 and right fixation seats 163 on the three right fixation straps 161. This allows the three left and right fixation straps 111 and 161 to loosen synchronously, enabling the child's feet to quickly detach from the brace. The entire process takes only a few seconds, eliminating the need to individually unfasten the Velcro or cut the straps, significantly reducing emergency response time. This allows for rapid evacuation in case of sudden discomfort or accidents, reducing the risk of skin ischemia, pressure sores, or joint damage caused by prolonged restraint. All buckles are located in easily accessible positions, facilitating efficient operation by parents or medical staff in emergencies and significantly improving safety during the child's rehabilitation process.

The lower surface of the right traction handle 221 is provided with the right traction spring 222 and the right traction rod 223 from the outside to the inside. The upper part of the surface of the right traction rod 223 is provided with a right traction thread 224. The right rotating nut 225 is threaded through the surface of the right traction thread 224. One end of the right traction assembly 22 is equipped with a right connecting rope 23, and one end of the right connecting rope 23 is provided with a right foot. The elastic band 24, the inner side of the left leg brace 9 is provided with a left leg fleece 25, and one side of the left leg fleece 25 is provided with a left leg hook surface 26. The left leg fleece 25 and the left leg hook surface 26 are Velcro. One side of the left leg hook surface 26 is provided with a left heating pad 27. The surface of the left fixing plate 10 is equipped with a left traction frame 28. The left traction frame 28 is provided with a left traction assembly 29 inside. The left traction assembly 29 includes a left traction handle 291, a left traction spring 292, and a left traction... The left extension handle 291 has a rod 293, a left extension thread 294, and a left rotating nut 295. The lower surface of the left extension handle 291 is provided with a left extension spring 292 and a left extension rod 293 from the outside to the inside. The upper part of the surface of the left extension rod 293 is provided with a left extension thread 294. The left rotating nut 295 passes through the thread of the left extension thread 294. A left connecting rope 30 is installed at one end of the left extension assembly 29. A left foot elastic band 31 is provided at one end of the left connecting rope 30.

[0055] When I put on the brace for the child, in order to adapt to the different stages of postoperative rehabilitation, it is necessary to adjust the upward traction force of the foot. By putting the left foot elastic band 31 on the child's foot, and by holding the left traction handle 291 and rotating the left rotating nut 295 clockwise, the left rotating nut 295 moves upward along the left traction thread 294, which causes the left traction rod 293 and the left traction spring 292 to shorten, thereby tightening the left connecting rope 30, raising the left foot elastic band 31 and applying a greater upward pulling force. By putting the right foot elastic band 24 on the child's foot, and by holding the right traction handle 221 and rotating the right rotating nut 221 clockwise, the traction force is adjusted accordingly. Nut 225 causes the right-hand rotating nut 225 to move upward along the right traction thread 224, which in turn shortens the right traction rod 223 and the right traction spring 222, thereby tightening the right connecting rope 23 and raising the right foot elastic band 24 to apply a greater upward pulling force. According to the doctor's advice, a smaller pulling force is set in the early stage after surgery, gradually increased in the middle stage, and stable traction is maintained in the later stage to promote Achilles tendon lengthening and recovery of foot dorsiflexion function. This achieves continuous and reversible adjustment of the traction force of the left foot elastic band 31 and the right foot elastic band 24, which can accurately match the different rehabilitation needs of clubfoot surgery from the initial immobilization to the middle stage weight-bearing and then to the later functional training.

[0056] By gently pressing and attaching the left leg felt 25 on the inside of the left leg brace 9 to the left leg hook 26 on the left heating pad 27, the left heating pad 27 is firmly adhered and fixed inside the left leg brace 9. Similarly, by gently pressing and attaching the right leg felt 18 on the inside of the right leg brace 14 to the right leg hook 19 on the right heating pad 20, the right heating pad 20 is firmly adhered and fixed inside the right leg brace 14. The left heating pad 27 and the right heating pad 20 then begin to generate heat, which is evenly distributed to the calf muscles and joints of the child, helping to relieve postoperative muscle tension, improve blood circulation, and promote tissue repair. The Velcro allows for quick installation and removal, reducing the problems of easy displacement and uneven temperature of traditional external heat packs. It also helps to reduce postoperative pain and prevent muscle atrophy, improving the child's comfort and compliance.

[0057] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0058] The technical solution provided by this invention is as follows: The left foot plate 1 and the right foot plate 5 are connected via the base plate sleeve 3 and the extension rod 4. The mis-touch sleeve 302 is removed from the mis-touch threaded seat 301 by rotating it. The locking head 703 is pulled upwards, causing the locking rod 702 to be pulled out of the extension fixing hole of the extension fixing rod 401. The locking spring 704 is pulled out, causing it to stretch and generate elastic force, pulling the locking head 703 out to the upper part of the locking groove 705. The locking head 703 is rotated and placed temporarily on the upper surface of the locking seat 701. The distance between the left foot plate 1 and the right foot plate 5 is adjusted by pulling the base plate sleeve 3 and the extension rod 4. After adjustment, the locking head 703 is rotated, and the elastic force of the locking spring 704 is applied. This allows the locking rod 702 to be inserted into the extension fixing hole of the corresponding extension fixing rod 401, and the locking head 703 to enter the locking groove 705 for fixation, ensuring that the extension rod 4 will not retract or shake due to walking or movement. By opening the left foot plate cover 2 and the right foot plate cover 6 on the left foot plate 1 and the right foot plate 5, and through the left control groove 101, left battery groove 102, left temperature and humidity groove 103 and left wire hole 104 opened on the left foot plate 1, and the right foot plate 5 also has a right control groove 501, right battery groove 502, right temperature and humidity groove 503 and right wire hole 504 at the corresponding position, control chip modules can be placed in the left control groove 101 and right control groove 501 respectively, and control chip modules can be placed in the left battery groove 102 and right battery groove 502 respectively, according to actual needs. The battery is used to place temperature and humidity sensors in the left and right temperature and humidity tanks 103 and 503 respectively, and to connect them with wires through the left and right wire holes 104 and 504 respectively. When the child is wearing the brace, the child's left foot is placed in the left foot brace 8 and the lower leg is put into the left leg brace 9. The initial fixation is completed by inserting the left fixing buckle 112 into the left fixing seat 113. The other two left fixing components 11 are adjusted and fixed in the positions of the lower leg and left foot respectively. After the initial fixation is completed, the left fixing strap 111 is adjusted to adjust the tightness of the child's left foot or lower leg by pulling or loosening one end of the left fixing hook surface 115 on the left fixing strap 111. After adjustment, the left fixing strap 111 is connected to the left fixing strap 111 by the left fixing hook surface 115 at one end of the left fixing strap 111. The left fixing surface 114 at the other end of the 11 is glued and fixed. The other two left fixing components 11 are adjusted and fixed in sequence. At the same time, the child's right foot is placed in the right foot brace 13 and the lower leg is put into the right leg brace 14. The initial fixation is completed by inserting the right fixing buckle 162 into the right fixing seat 163. The other two right fixing components 16 are adjusted in sequence and fixed in the position of the lower leg and the right foot respectively. After the initial fixation is completed, the right fixing hook surface 165 on the right fixing strap 161 is pulled or loosened to adjust the tightness of the right fixing strap 161 on the child's right foot or lower leg. After adjustment, the right fixing hook surface 165 at one end of the right fixing strap 161 is glued and fixed to the right fixing surface 164 at the other end of the right fixing strap 161.After adjusting the tightness of the other two right fixation components 16 in sequence, they are fixed in place. When I put the brace on the child, in order to adapt to the different rehabilitation needs of the child at different stages after surgery, it is necessary to adjust the upward traction force of the foot. By putting the left foot elastic band 31 on the child's foot, by holding the left traction handle 291 and rotating the left rotating nut 295 clockwise, the left rotating nut 295 moves upward along the left traction thread 294, which drives the left traction rod 293 and the left traction spring 292 to shorten, thereby tightening the left connecting rope 30, raising the left foot elastic band 31 and applying a greater upward pulling force. The right foot elastic band 24 is placed on the child's foot. By holding the right traction handle 221 and rotating the right rotating nut 225 clockwise, the right rotating nut 225 moves upward along the right traction thread 224, causing the right traction rod 223 and the right traction spring 222 to shorten. This tightens the right connecting rope 23, causing the right foot elastic band 24 to rise and apply a greater upward pull. According to the doctor's advice, a smaller pull is set in the early postoperative period, gradually increased in the middle period, and stable traction is maintained in the later period to promote Achilles tendon lengthening and recovery of foot dorsiflexion function. The left leg brace 9 is connected to the left leg felt 25 on the inside of the left leg brace 9 and the left heating pad 2. Gently press and adhere the left leg hook surface 26 on the left leg brace 9 to firmly attach the left heating pad 27 to the left leg brace 9. Then, gently press and adhere the right leg hook surface 19 on the right heating pad 20 to the right leg brace 14 via the right leg felt surface 18 on the inside of the right leg brace 14 to firmly attach the right heating pad 20 to the right leg brace 14. The left and right heating pads 27 and 20 will then generate heat, which will be evenly distributed to the child's calf muscles and joints, helping to relieve postoperative muscle tension, improve blood circulation, and promote tissue repair. If the child experiences significant discomfort during use, such as crying, skin redness, or other symptoms, please consult a doctor. When the child shows signs of pain, I need to immediately remove the brace. Simultaneously, personnel quickly press the release buttons on the left and right fixation clips 112 and 162, instantly separating the left fixation clips 112 and left fixation seats 113 on the three left fixation straps 111, and the right fixation clips 162 and right fixation seats 163 on the three right fixation straps 161. This allows the three left and right fixation straps 111 and 161 to loosen synchronously, enabling the child's feet to quickly come off the brace. The entire process takes only a few seconds, without needing to individually unfasten the Velcro or cut the straps, greatly shortening emergency treatment time.
