Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a dynamic correction device for seated scoliosis combined with pelvic tilt. Background Technology

[0002] Scoliosis, commonly known as scoliosis, refers to a spinal deformity in which one or more segments of the spine curve laterally or are accompanied by vertebral rotation. Clinical studies have shown that scoliosis is often accompanied by pelvic tilt, and the degree of pelvic tilt is more pronounced in individuals with a lower apical vertebra. Traditional scoliosis correctors have significant limitations: firstly, they only correct the spinal deformity and fail to address pelvic tilt simultaneously; secondly, existing devices are generally bulky and only suitable for fixed-point rehabilitation treatment, unable to meet the needs of daily activities; thirdly, the correction process lacks dynamic adjustment capabilities, requiring frequent manual adjustments, which increases operational complexity and affects user comfort. Particularly noteworthy is that existing static correction methods cannot respond to changes in the user's posture in real time, making it difficult to balance corrective effectiveness with comfort. Furthermore, traditional devices have poor adaptability in seated positions and lack intelligent triggering mechanisms to coordinate the dual needs of spinal correction and pelvic balance. These problems severely restrict the practical application of corrective devices, necessitating the development of a comprehensive solution that enables dynamic adjustment, simultaneous correction, and ease of daily use. Summary of the Invention

[0003] The purpose of this application is to provide a dynamic correction device for seated scoliosis and pelvic tilt, as well as its auxiliary mechanism and triggering component, which has the advantages of being able to simultaneously correct scoliosis and pelvic tilt, achieve dynamic adjustment, adapt to seated posture, improve comfort and ease of use.

[0004] The sitting scoliosis combined with pelvic tilt dynamic correction device provided by this invention adopts the following technical solution: A dynamic correction device for seated scoliosis combined with pelvic tilt, including: The waist clip has two parts, each with a rotating groove on its inner side. The bottom of the waist clip is rotatably connected to a leg plate, and the leg plate is equipped with a leg binding assembly. A pelvic support pad is connected between the two waist clips, and a hollow side limiting plate is fixedly connected to the outer wall of the waist clip. The correction mechanism is located on the side limiting plate. The correction mechanism includes a front and rear cable for dynamic adjustment. Multiple first and second winches are rotatably connected to the inner wall of the side limiting plate. The front and rear cable are wound on the first and second winches respectively. An auxiliary mechanism is located inside the side limiting plate and is used to push against both sides of the body when in a sitting position; An inductive switch is embedded in the inner wall of the rotating groove, and the inductive switch is signal-connected to the first winch and the second winch. The trigger component is located on the waist clip and is linked with the auxiliary mechanism, and is triggered when the user is in a seated position.

[0005] Furthermore, this application also proposes that the auxiliary mechanism includes a vertical track and a horizontal slide rail. The vertical track is embedded in the inner wall of the side limiting plate, and a vertical push plate is slidably connected in the vertical track. The two ends of the horizontal slide rail are respectively fixedly connected to the inner wall of the side limiting plate, and a top block is slidably connected in the horizontal slide rail. Multiple wedge blocks are equidistantly arranged on the side of the vertical push plate near the top block, and the shape of the wedge blocks matches and abuts against the top block.

[0006] Furthermore, this application also proposes that the wedge block is positioned between two horizontal slide rails, and the bottom of the vertical push plate extends a vertical rail to contact the trigger component.

[0007] Furthermore, this application also proposes that the top block near the outer side of the side limiting plate is spherical, and the spherical surface is provided with multiple protruding points.

[0008] Furthermore, this application also proposes that the triggering component includes a synchronous rotating plate and a rotating rod, the rotating rod being rotatably connected in the rotating groove and one end being fixedly connected to the rotating shaft of the leg plate, the synchronous rotating plate being fixedly connected to the rotating rod, a reset spring being provided between the rotating rod and the inner wall of the rotating groove, and one end of the rotating rod extending into the side limiting plate and being fixedly connected to a rocker arm, the rocker arm abutting against the bottom of the vertical push plate.

[0009] Furthermore, this application also proposes that the synchronous rotating plate sweeps across the induction switch while the user is seated, and at the same time the rocker arm pushes the vertical push plate to its highest point.

[0010] Furthermore, this application also proposes that the leg strap assembly includes a strap and a leg pad, the leg pad being detachably connected to the leg plate, one end of the strap being connected to the outside of the leg pad, and the other end being connected to the leg plate via a buckle.

[0011] Furthermore, this application also proposes that the front of the two waist clips be detachably connected to a front cover, and that the outer wall of the side limiting plate near the body be detachably connected to a rubber sleeve to improve comfort.

[0012] Furthermore, this application also proposes that the front cable adopts a segmented structure, with a soft connector detachably connected between the two segments of the front cable.

[0013] In summary, the present invention has at least the following beneficial technical effects: 1. Through the coordinated work of the lumbar support, leg support, pelvic support pad, side limiting plate, correction mechanism, auxiliary mechanism, sensor switch and triggering component, dynamic correction is automatically triggered in the sitting position to simultaneously solve the problems of scoliosis and pelvic tilt. It has the advantages of being able to simultaneously correct scoliosis and pelvic tilt, achieve dynamic adjustment, adapt to sitting position, improve comfort and ease of use. 2. By dynamically adjusting the tension of the front and rear braces of the correction mechanism, the spine is restrained. The auxiliary mechanism also serves as a reminder; when the body tilts to a certain degree, the auxiliary mechanism will "prick" the body, prompting the user to return to the correct sitting posture, thus meeting the user's needs.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0023] This invention discloses a dynamic correction device for seated scoliosis combined with pelvic tilt.

[0025] Reference Figures 1-7 A dynamic correction device for seated scoliosis combined with pelvic tilt, including: The system comprises a lumbar support 1, a correction mechanism 2, an auxiliary mechanism 3, a sensor switch 4, and a trigger assembly 5. Two lumbar support pieces 1 are provided, each with a rotating groove on its inner side. A leg plate 14 is rotatably connected to the bottom of each piece, and a leg strap assembly is mounted on the leg plate 14. A pelvic support pad 16 connects the two lumbar support pieces 1, and a hollow side limiting plate 12 is fixedly connected to the outer wall of each lumbar support piece 1. The correction mechanism 2 is located on the side limiting plate 12 and includes a front cable 21 and a rear cable 22 for dynamic adjustment. Multiple first winches 24 and second winches 25 are rotatably connected to the inner wall of the side limiting plate 12, and the front cable 21 and rear cable 22 are wound around the first winches 24 and second winches 25, respectively. The auxiliary mechanism 3 is located within the side limiting plate 12 and is used to provide pressure on both sides of the body when seated. The sensor switch 4 is embedded in the inner wall of the rotating groove and is signal-connected to the first winches 24 and second winches 25. The trigger component 5 is mounted on the lumbar support 1 and is linked with the auxiliary mechanism 3, triggering when the user is seated. This structure enables combined dynamic correction of scoliosis and pelvic tilt, especially in the seated position, allowing for real-time adjustments based on changes in body posture, thus improving the intelligence and comfort of the correction.

[0026] For ease of understanding, the following explains some key terms in this embodiment: The lumbar support 1, which generally refers to the structural component used to fix and support the sides of the human waist, is usually set in pairs in this application and serves as the main frame of the entire correction device.

[0027] The leg plate 14, which generally refers to a plate-like structure used to support and fix the human legs, is rotatably connected to the waist clip 1 in this application to adapt to the change of sitting or standing posture, making it more suitable for daily life use.

[0028] Leg strap assembly, which generally refers to the component used to secure the legs to the leg plate 14 to ensure the stability of the leg posture.

[0029] The pelvic support pad 16, which generally refers to a soft pad structure used to support and lift the pelvic region of a human body, is connected between two lumbar clips 1 in this application to provide pelvic support and correction.

[0030] Side limiting plate 12, which generally refers to a plate-like structure set on the outside of waist clamp 1, is used to restrict lateral movement of the body and serves as a mounting carrier for other mechanisms.

[0031] Correction mechanism 2, which generally refers to an actuator used for dynamic correction of the spine and pelvis, in this application, achieves tension adjustment through the cooperation of ropes and winches.

[0032] The front drawstring 21 and the rear drawstring 22, which generally refer to flexible ropes used to apply tension to correct body posture, apply force to the torso from the front and rear sides of the body, respectively, in this application.

[0033] The first winch 24 and the second winch 25 are generally rotating mechanical components used for winding and releasing ropes. In this application, they adjust the length and tension of the front rope 21 and the rear rope 22 by rotating. It should be noted that tension sensors can be added to the front rope 21 and the rear rope 22 to further improve intelligent dynamic adjustment and meet the usage requirements.

[0034] Auxiliary mechanism 3, which usually refers to a mechanism that provides additional support or top contact to the sides of the body in a specific posture (such as sitting) to assist in correction and serve as an alert.

[0035] The inductive switch 4, which is generally an electronic component that can detect a specific state (such as rotation angle or position change) and output a signal, is used in this application to detect sitting posture.

[0036] Triggering component 5, which typically refers to a mechanical or electronic component that is activated under specific conditions (such as a sitting posture) and drives the action of other mechanisms, is linked with auxiliary mechanism 3 in this application.

[0037] Rotation grooves typically refer to recesses located inside structural components, used to accommodate and guide the rotation of other parts.

[0038] The seated scoliosis combined with pelvic tilt dynamic correction device of this application has a lumbar support 1 made of materials such as metal or high-strength plastic. Its shape can be designed as an arc-shaped structure that conforms to the curve of the human waist to provide support. Two lumbar support 1s are symmetrically arranged on both sides of the human body, and their inner sides can have rotation grooves for accommodating rotating components. The leg plate 14 can be a flat plate, connected to the bottom of the lumbar support 1 by means of pins or hinges to achieve rotation. The leg binding assembly can be made of simple Velcro or buckle straps to fix the legs to the leg plate 14. The pelvic support pad 16 can be a pad made of soft material, connected between the two lumbar support 1s by bolts or adhesive to fit and support the pelvis. The side limiting plate 12 can be a hollow plate structure, fixed to the outer wall of the lumbar support 1 by welding or screws, and its internal space is used to install other mechanisms.

[0039] The correction mechanism 2 can be installed inside the side limiting plate 12. The front and rear cable ropes 21 and 22 can be high-strength, low-elasticity fiber ropes, with one end fixed to the side limiting plate 12 and the other end leading out through a guide hole and contacting the human torso. The first winch 24 and the second winch 25 can be composed of motor-driven or manually rotated drums, rotatably connected to the inner wall of the side limiting plate 12 via bearings. The front and rear cable ropes 21 and 22 are respectively wound around the corresponding first and second winches 24 and 25. The rotation of the winches achieves the winding and unwinding of the ropes, thereby adjusting the tension on the torso. For example, when a corrective force needs to be applied in a certain direction, the corresponding winch can tighten the rope, increasing the tension. Sensors can be added here to detect changes in the force on the front and rear cable ropes 21 and 22.

[0040] When the device is in a seated position, the auxiliary mechanism 3 applies a continuous top-touching force to the side of the body to help correct scoliosis or pelvic tilt and to serve as an alert.

[0041] The inductive switch 4 can be a microswitch, a Hall sensor, or a photoelectric sensor, and it is fixed or embedded in the rotating groove wall inside the waist clip 1. When the component (synchronous rotating plate 51) that cooperates with the rotating groove rotates to a specific position, the inductive switch 4 is triggered, generating an electrical signal. This signal can be transmitted to a controller, which then sends instructions to the motors driving the first winch 24 and the second winch 25, thereby realizing the movement of the winches.

[0042] One end of the trigger component 5 is connected to the rotation axis of the leg plate 14, and the other end is connected to the drive component of the auxiliary mechanism 3. When the leg plate 14 rotates from a standing posture (e.g., in a straight line with the waist clamp 1) to a sitting posture (e.g., at a certain angle with the waist clamp 1), the linkage mechanism of the trigger component 5 is driven, thereby driving the auxiliary mechanism 3 to move and achieve contact with the body.

[0043] The seated scoliosis and pelvic tilt dynamic correction device of this application achieves simultaneous dynamic correction of scoliosis and pelvic tilt through the coordinated action of the lumbar support 1, the correction mechanism 2, the auxiliary mechanism 3, the induction switch 4, and the triggering component 5. The device can automatically trigger the auxiliary mechanism 3 for top contact support based on the seated posture, and combined with the cable tension adjustment of the correction mechanism 2, effectively solves the problems of insufficient correction in seated posture, cumbersome adjustment, and lack of intelligent dynamic response in traditional orthotics, significantly improving the accuracy of correction and the user's comfort experience.

[0044] In some of the embodiments described above in this application, an auxiliary mechanism 3 is proposed for touching the sides of the body when sitting. However, in its implementation, how to ensure that the touching mechanism can be dynamically adjusted precisely as needed and effectively linked with the trigger component 5 to adapt to different users' physical conditions and correction needs is a technical problem that needs to be further refined and solved.

[0045] In response, this application further proposes a specific structure for the auxiliary mechanism 3, which includes a vertical track 31 and a horizontal slide rail 33. The vertical track 31 is embedded in the inner wall of the side limiting plate 12, and a vertical push plate 32 is slidably connected within the vertical track 31. Both ends of the horizontal slide rail 33 are fixedly connected to the inner wall of the side limiting plate 12, and a top block 34 is slidably connected within the horizontal slide rail 33. Multiple wedge-shaped blocks 35 are equidistantly arranged on the side of the vertical push plate 32 near the top block 34, and the shape of the wedge-shaped blocks 35 matches and abuts against the top block 34.

[0046] Specifically, the vertical track 31 is a structure used to guide vertical movement. Its inner wall is precision-machined to ensure smooth sliding of the vertical push plate 32. The vertical track 31 is embedded in the inner wall of the side limiting plate 12, meaning it is integrated into the internal structure of the side limiting plate 12 rather than simply attached to its surface. This helps save space, improves structural compactness, and protects the track from external damage. The vertical push plate 32 is a key component of the auxiliary mechanism 3. It can move up and down within the vertical track 31. Its side can be equipped with sliders or protrusions that match the vertical track 31, achieving smooth sliding through low-friction materials or ball bearings, serving as a medium for transmitting vertical movement. The horizontal slide rail 33 is a structure used to guide horizontal movement. Its two ends are fixedly connected to the inner wall of the side limiting plate 12, providing stable support and guidance for the horizontal movement of the top block 34. The top block 34 is the component that directly contacts the user's body and applies pressure. It can move left and right within the horizontal slide rail 33. Its bottom or side may have sliders or rollers that match the horizontal slide rail 33 to reduce friction. Multiple wedge blocks 35 are equidistantly arranged on the side of the vertical push plate 32 near the top block 34. These wedge blocks 35 are key components for adjusting the pressure. They can be integrally molded onto the vertical push plate 32 or manufactured separately and then fixed. The equidistant arrangement provides uniform and predictable adjustment steps. The shape of the wedge blocks 35 matches and abuts against the top block 34, ensuring stable contact, reducing wear, and achieving smooth and controllable pressure adjustment. Typically, the wedge blocks 35 have an inclined surface, while the top block 34 has a matching inclined or curved surface.

[0047] By introducing a combined structure of a vertical track 31, a horizontal slide rail 33, a vertical push plate 32, a top block 34, and wedge blocks 35, this application provides a mechanically linked auxiliary mechanism 3. When the trigger component 5 is activated, it links the vertical push plate 32 to move vertically. Multiple wedge blocks 35, equidistantly arranged on the vertical push plate 32, mate and abut against the top block 34, precisely converting the vertical displacement of the vertical push plate 32 into the horizontal displacement of the top block 34. This allows the auxiliary mechanism 3 to achieve dynamic, graded contact with both sides of the body, providing adjustable support and corrective force according to the user's posture and correction needs. Compared to simple fixed or single-adjustment contact mechanisms, this solution achieves precise and repeatable adjustment of the contact position and force through mechanical transmission, significantly improving the adaptability and effectiveness of the correction device and ensuring comfort and personalization during the correction process.

[0048] Reference Figures 1-7This application further proposes that the wedge block 35 is positioned between two horizontal slide rails 33, and the bottom of the vertical push plate 32 extends out to form a vertical track 31 that contacts the trigger component 5. The wedge block 35 is positioned and constrained between the two horizontal slide rails 33, meaning that the horizontal slide rails 33 not only provide a sliding path for the top block 34 but also guide and restrict the lateral position of the wedge block 35. This design ensures that the wedge block 35 maintains precise alignment and stable engagement with the top block 34 as the vertical push plate 32 moves up and down, preventing unnecessary lateral offset or wobbling of the wedge block 35. Specifically, the width of the wedge block 35 can be designed to be slightly smaller than the distance between the inner walls of the two horizontal slide rails 33, thereby allowing vertical movement while effectively preventing free lateral movement. Furthermore, the bottom structure of the vertical push plate 32 is designed to extend beyond the lower end of the vertical track 31 it is located on, and directly contact the trigger component 5. This extended design establishes a direct mechanical connection, enabling the vertical displacement of the vertical push plate 32 to be reliably transmitted to the trigger assembly 5.

[0049] Through the above technical solution, the wedge block 35 is confined between two horizontal slide rails 33, greatly enhancing the lateral stability of the wedge block 35 during vertical movement. This ensures that the wedge block 35 can always maintain precise alignment and stable engagement with the top block 34, thereby enabling the auxiliary mechanism 3 to provide more precise and consistent support when contacting both sides of the body, effectively improving the accuracy and comfort of the correction, and avoiding poor correction results caused by component misalignment. At the same time, the bottom of the vertical push plate 32 extends a vertical track 31 and directly contacts the trigger component 5, establishing a direct and reliable mechanical linkage mechanism. This allows the displacement of the vertical push plate 32 in the sitting position to be accurately sensed by the trigger component 5, thereby ensuring that the correction device can timely and accurately identify the user's sitting posture and activate the corresponding correction function. This direct mechanical triggering method simplifies the system structure, improves the reliability and response speed of the trigger, effectively solves the problems of inaccurate sitting posture detection or untimely triggering of correction actions, and thus improves the intelligence and user experience of the entire correction device.

[0050] Reference Figures 1-7 Furthermore, this application proposes that the top block 34 is spherical in shape near the outer side of the side limiting plate 12, and the spherical surface is provided with multiple protruding points.

[0051] Specifically, the top block 34 is designed with a spherical shape near the outer side of the side limiting plate 12. The spherical surface provides a softer and more adaptive contact interface, and furthermore, it is provided with multiple raised points. These raised points effectively increase the friction between the top block 34 and the body, preventing unnecessary relative sliding between the body and the top block 34 during correction and ensuring stable application of the corrective force. Simultaneously, these raised points also provide a slight massage effect upon contact, helping to promote local blood circulation and reminding the wearer to adjust their posture.

[0052] In some embodiments described above in this application, a dynamic correction device for seated scoliosis combined with pelvic tilt is proposed, which includes a sensor switch 4 for detecting seated posture and a trigger component 5 for triggering an auxiliary mechanism 3 in a seated state. However, in practical applications, ensuring that the trigger component 5 can accurately and reliably detect the seated posture and effectively link the auxiliary mechanism 3 for contact, while ensuring the device resets in a non-seated state, is key to achieving automation and convenience of the device. Improper trigger mechanism design may lead to false triggering or insensitive triggering, affecting the correction effect and user experience.

[0053] In this regard, refer to Figures 1-7 This application further discloses the specific structure of the trigger assembly 5, which includes a synchronous rotating plate 51 and a rotating rod 52. The rotating rod 52 is rotatably connected in the rotating groove, and one end of it is fixedly connected to the rotating shaft of the leg plate 14. The synchronous rotating plate 51 is fixedly connected to the rotating rod 52. A return spring 53 is provided between the rotating rod 52 and the inner wall of the rotating groove. The other end of the rotating rod 52 extends into the side limiting plate 12, and a rocker arm 54 is fixedly connected to this end, which abuts against the bottom of the vertical push plate 32.

[0054] Specifically, the synchronous rotating plate 51 in the trigger assembly 5 is typically a plate-shaped structure. Its size and shape can be optimized according to the type and location of the inductive switch 4 to ensure effective triggering of the inductive switch 4 during rotation. Its material can be engineering plastics or lightweight metals with good mechanical strength. The rotating rod 52, as the core transmission component, is typically a cylindrical rod made of high-strength metal to ensure stability and durability when transmitting rotational and contact forces. The rotating rod 52 is rotatably connected to the rotating groove of the waist clamp 1 via bearings or bushings to ensure smooth rotation. The synchronous rotating plate 51 and the rotating rod 52 are also fixedly connected, for example, by screws, riveting, or interference fit, to ensure synchronous rotation. To automatically reset when the user leaves the seated position, a reset spring 53 is provided between the rotating rod 52 and the inner wall of the rotating groove. This spring is typically a torsion spring or a coil spring, and its preload is precisely calculated to provide sufficient reset force. The other end of the rotating rod 52 extends into the side limiting plate 12, where a rocker arm 54 is fixedly connected. The rocker arm 54 is typically a lever-shaped structure, and its material is similar to that of the rotating rod 52. The free end of the rocker arm 54 maintains a contact relationship with the bottom of the vertical push plate 32 in the auxiliary mechanism 3. This contact can be a point contact or a surface contact to ensure that the rotation of the rotating rod 52 can be effectively converted into a vertical pushing force on the vertical push plate 32.

[0055] Through the above technical solution, when the user sits down, the leg plate 14 will rotate downwards due to gravity or the pressure of the user's legs. Since the rotating rod 52 is fixedly connected to the rotation shaft of the leg plate 14, the rotating rod 52 will rotate synchronously. The rotation of the rotating rod 52 drives the synchronous rotating plate 51 to rotate, so that it can sweep across or trigger the induction switch 4, thereby sending a sitting posture signal to the correction mechanism 2, providing a prerequisite for subsequent dynamic correction. On the other hand, the rotation of the rotating rod 52, through the contact between the rocker arm 54 and the vertical push plate 32, converts the rotation into a vertical push on the vertical push plate 32, so that the auxiliary mechanism 3 can make contact adjustments according to the sitting posture. The setting of the return spring 53 ensures that when the user leaves the sitting posture, the leg plate 14, the rotating rod 52, the synchronous rotating plate 51, and the rocker arm 54 can automatically return to their original positions, ready for the next use. This ingenious mechanical linkage design realizes the automatic detection of the sitting posture and the synchronous triggering of the auxiliary mechanism, improves the automation level and ease of use of the device, and ensures the timeliness and effectiveness of the correction process.

[0056] Reference Figures 1-7This application further proposes that the aforementioned synchronous rotating plate 51 sweeps across the induction switch 4 in a seated position, while simultaneously the rocker arm 54 pushes the vertical push plate 32 to its highest point. Specifically, when the user is in a seated position, the leg plate 14 rotates. Since one end of the rotating rod 52 is fixedly connected to the rotation axis of the leg plate 14, and the synchronous rotating plate 51 is fixedly connected to the rotating rod 52, the rotation of the leg plate 14 will drive the rotating rod 52 and the synchronous rotating plate 51 to rotate synchronously. The rotation trajectory of the synchronous rotating plate 51 is designed to pass through the sensing area of ​​the induction switch 4 in a seated position. The induction switch 4 can be a photoelectric sensor, a Hall sensor, or a mechanical limit switch, etc., used to detect the passage or presence of the synchronous rotating plate 51, thereby generating a clear electrical signal indicating that the user is currently in a seated position. At the same time, the rocker arm 54 is part of the trigger assembly 5, which is fixedly connected to the rotating rod 52 and abuts against the bottom of the vertical push plate 32 in the auxiliary mechanism 3. When the user is in a seated position, the rotation of the leg plate 14 drives the rocker arm 54 to rotate or move through the rotating rod 52. The structure and installation position of the rocker arm 54 are precisely designed to ensure that when the seated posture is fully formed, it can push the vertical push plate 32 upward to its preset highest position. The highest point of the vertical push plate 32 corresponds to the optimal contact state between the wedge block 35 and the top block 34 in the auxiliary mechanism 3, thereby achieving maximum contact or support on both sides of the body.

[0057] Through the above technical solution, when the user is in a seated position, the synchronous rotating plate 51 precisely sweeps across the induction switch 4, providing a clear and unambiguous posture signal, ensuring that the correction mechanism 2 can receive the trigger command in a timely and accurate manner. Simultaneously, the rocker arm 54 pushes the vertical push plate 32 to its highest point, ensuring that the auxiliary mechanism 3 can contact both sides of the body with the preset maximum strength and position, thereby achieving the best correction effect for scoliosis and pelvic tilt. This linkage mechanism ensures the responsiveness of the correction device in a seated position and the stability and consistency of the correction effect.

[0058] In some of the above embodiments, the leg plate 14 of the seated scoliosis combined with pelvic tilt dynamic correction device is equipped with a leg binding assembly for fixing the user's legs. However, in practical applications, traditional leg binding assemblies may have problems such as insufficient comfort, insecure fixation, or inconvenient cleaning and maintenance, affecting the correction effect and user experience.

[0059] In this regard, refer to Figure 1 and Figure 2 This application further discloses the specific structure of the leg binding assembly, which includes a strap 15 and a leg pad 17. The leg pad 17 is detachably connected to the leg plate 14, and one end of the strap 15 is connected to the outside of the leg pad 17, while the other end is snapped into the leg plate 14.

[0060] Specifically, the leg binding assembly is a functional component used to secure the user's legs to the leg plate 14. Its core function is to provide stable support and restraint to ensure the maintenance of corrective posture. The straps 15, as the main fixing component of the leg binding assembly, are typically made of flexible and durable materials such as nylon, Velcro, or elastic fabric. They are designed to wrap around the user's legs and connect with the leg plate 14 to achieve a secure fixation of the legs. The design of the straps 15 takes into full consideration the pressure distribution on the legs to avoid excessive localized pressure while ensuring sufficient fixing force.

[0061] The above technical solution introduces a leg-binding assembly consisting of straps 15 and leg pads 17, employing a detachable connection between the leg pads 17 and the leg plate 14, and a snap-fit ​​connection between the straps 15 and the leg plate 14. This significantly improves the practicality and user experience of the orthodontic device. The leg pads 17 effectively increase the comfort of the leg in contact with the device, reducing the pressure and discomfort that may be caused by prolonged wear. The detachable design of the leg pads 17 greatly facilitates cleaning and maintenance, ensuring the hygiene of the device and extending its service life. Simultaneously, the synergistic effect of the straps 15 and leg pads 17, as well as the snap-fit ​​connection between the straps 15 and the leg plate 14, not only provides a stable and reliable leg fixation effect, preventing leg displacement during dynamic correction, but also allows users to quickly and easily put on and take off the device, improving operational efficiency. This design ensures the stability and comfort of the correction process, thereby contributing to improved overall correction results and ease of wear.

[0062] Reference Figures 1-7 This application further proposes that the front of the two waist clips 1 is detachably connected to a front cover 13, and the outer wall of the side limiting plate 12 near the body is detachably connected to a rubber sleeve 11 to improve comfort.

[0063] Specifically, the front support 13 is a structure used to connect the two lumbar support clips 1. It is typically located in front of the user's body and is designed to provide forward support and restraint. The front support 13 can be made of various materials, and its shape should be designed with ergonomic principles in mind to ensure effective support without affecting the user's breathing and movement, and to comfortably conform to the body's curves. The detachable connection between the front support 13 and the lumbar support clips 1 can be varied, such as using a snap-on mechanism, bolt fixing, Velcro adhesion, or quick-release locks, to facilitate installation, removal, adjustment, or cleaning as needed. The main function of the front support 13 is to provide stable forward support for the user, effectively preventing forward leaning or involuntary postural changes during correction, thereby helping to maintain correct posture and enhancing the overall stability and safety of the entire correction device.

[0064] Meanwhile, the rubber sleeve 11 is a soft protective layer designed to cover the outer wall of the side limiting plate 12 closest to the body. The rubber sleeve 11 can be made of medical-grade silicone, soft rubber, elastic foam, or other elastic materials with good biocompatibility, cushioning properties, and breathability. Its detachable connection can be achieved through a slip-on design, hook and loop fasteners, slotted fasteners, or magnetic attachment, facilitating daily cleaning, disinfection, or replacement to maintain hygiene. The main function of the rubber sleeve 11 is to significantly increase the softness of the area where the device contacts the body, effectively reducing direct pressure and friction from hard materials on the skin, thereby greatly improving wearing comfort and preventing skin redness, damage, or discomfort that may occur with prolonged wear.

[0065] Through the aforementioned technical solution, a front panel 13 is detachably connected to the front of the two waist clips 1. This device provides additional support and restraint to the user's front body, effectively preventing forward leaning or involuntary postural changes, thereby enhancing the overall stability of the corrective device and the sustainability of its corrective effect. Simultaneously, a rubber sleeve 11 is detachably connected to the outer wall of the side limiting plate 12 near the body, significantly improving the softness and comfort of the contact area between the device and the body. This effectively alleviates the pressure and friction that may be caused by hard materials, greatly improving user compliance during prolonged wear and ensuring the smooth progress of the correction process. These improvements collectively enhance the device's practicality and user experience.

[0066] Reference Figures 1-7 This application further proposes that the front cable 21 adopts a segmented structure, and a soft connector 23 is detachably connected between the two segments of the front cable 21.

[0067] The front drawstring 21 adopts a segmented structure, meaning that it is no longer a single, continuous rope, but consists of at least two independent rope segments. This segmented design allows for the introduction of flexible or adjustable components at specific locations on the rope to better adapt to the curves of the body or avoid direct pressure on sensitive areas, thereby improving the rope's adaptability and comfort, and facilitating local adjustments or replacements at specific locations for easy wear.

[0068] The following example will provide a more detailed explanation of the above technical solution: In a rehabilitation center, a patient with scoliosis and pelvic tilt needed seated corrective training. Traditional orthotics are bulky and cannot be dynamically adjusted, making them difficult for patients to use consistently in daily life, and the correction process is cumbersome and uncomfortable. To address these issues, the rehabilitation center introduced a seated scoliosis and pelvic tilt dynamic correction device.

[0069] When the patient is ready for correction, the two lumbar clips 1 of the device are first secured to both sides of the waist. A leg plate 14 is rotatably connected to the bottom of the lumbar clip 1. The patient places both legs on the leg plate 14 and secures the lower legs to the leg plate 14 using the leg binding assembly (including straps 15 and leg pads 17) to ensure lower limb stability. A pelvic support pad 16 is connected between the two lumbar clips 1, providing support for the patient's pelvis, thus addressing pelvic tilt while correcting the spine. To improve wearing comfort, a rubber sleeve 11 is detachably connected to the outer wall of the side limiting plate 12 closest to the body. Furthermore, a front panel 13 is detachably connected to the front of the two lumbar clips 1, further enhancing the overall stability and coverage of the device.

[0070] When the patient sits down, their posture triggers the device's linkage mechanism. Specifically, the trigger component 5 is mounted on the lumbar support 1, and includes a rotating rod 52 and a synchronous rotating plate 51. The rotating rod 52 is rotatably connected to a rotating groove inside the lumbar support 1, and one end is fixedly connected to the rotating shaft of the leg plate 14. When the patient sits down, the leg plate 14 rotates relative to the lumbar support 1, and the rotating rod 52 rotates accordingly. The synchronous rotating plate 51, fixedly connected to the rotating rod 52, sweeps across the inductive switch 4 embedded in the inner wall of the rotating groove. After receiving a signal, the inductive switch 4 sends a signal to the first winch 24 and the second winch 25 of the correction mechanism 2, preparing for subsequent dynamic correction.

[0071] Meanwhile, the other end of the rotating rod 52 extends into the side limiting plate 12 and is fixedly connected to a rocker arm 54. When the patient sits down, the rocker arm 54 tilts upward, abutting and lifting the bottom of the vertical push plate 32 of the auxiliary mechanism 3, allowing it to slide to the highest point of the vertical track 31. Multiple wedge-shaped blocks 35 are equidistantly arranged on the side of the vertical push plate 32 near the top block 34. The shape of these wedge-shaped blocks 35 matches and abuts against the top block 34, which is slidably connected within the horizontal slide rail 33. When the vertical push plate 32 is lifted, the wedge-shaped blocks 35 push the top block 34 inward, causing it to extend from the inner wall of the side limiting plate 12, providing support to both sides of the patient's body. The top block 34 near the outer side of the side limiting plate 12 is spherical, and its spherical surface is provided with multiple raised points, which helps to provide more comfortable and massage-like support, as well as a warning function.

[0072] After the patient's sitting posture is stabilized, the correction mechanism 2 begins to operate. The correction mechanism 2 is located within the side limiting plate 12 and includes a front cable 21 and a rear cable 22. The front cable 21 and the rear cable 22 are respectively wound around multiple first winches 24 and second winches 25 rotatably connected to the inner wall of the side limiting plate 12. After being triggered by the synchronous rotating plate 51, the inductive switch 4 sends a signal to the first winches 24 and second winches 25, activating their dynamic adjustment function. Depending on the specific condition of the patient's scoliosis and pelvic tilt, the first winches 24 and second winches 25 intelligently tighten or loosen the front cable 21 and the rear cable 22, applying a dynamic and personalized corrective force to the patient's trunk. For example, if the patient has right-sided scoliosis, the device will guide the patient's trunk to rotate and bend to the left by adjusting the tension of the left-side front cable 21 and the rear cable 22, as well as the contact force of the right-side auxiliary mechanism 3, while simultaneously correcting pelvic tilt through the cooperation of the pelvic support pad 16 and the leg board 14. The front cord 21 has a segmented structure, and a soft connector 23 is detachably connected between the two front cords 21. This allows the device to better adapt to the patient's body curves and improve comfort while providing corrective force.

[0073] Compared to existing devices that require manual adjustment of gear positions and have an inconsistent correction process, this device achieves automatic triggering and automatic adjustment of the auxiliary mechanism 3 in a seated state through the linkage of the induction switch 4 and the trigger component 5, greatly simplifying the operation process. Simultaneously, the front and rear straps 21 and 22 of the correction mechanism 2 can be dynamically adjusted, rather than fixed, making the correction process more intelligent and personalized. It can fine-tune according to the patient's real-time posture changes, thus providing a more precise and comfortable correction experience. This solution, which combines spinal correction with pelvic tilt correction and achieves dynamic intelligent adjustment, effectively solves the problems of traditional orthodontic appliances being bulky, inconvenient for daily use, cumbersome in the correction process, and lacking dynamic intelligence, significantly improving patient compliance and correction effectiveness.

[0074] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
