Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a scoliosis orthosis with adjustable correction. Background Technology

[0002] Scoliosis is a common skeletal deformity in adolescents and some adults. Clinically, it is usually treated conservatively with a rigid scoliosis brace for a long period of time. To achieve the desired corrective effect, patients need to wear the brace for 16 to 23 hours a day. In this prolonged wearing scenario, the brace must continuously apply high-intensity physical pressure to the patient's trunk. However, when patients lie flat to sleep at night or rest in a supine position during the day, the continuous static high pressure on the trunk can significantly restrict the respiratory expansion of the thoracic cavity, leading to a feeling of tightness and local muscle tenderness. This severely reduces the patient's sleep quality and long-term adherence to the brace.

[0003] To address the aforementioned pain points associated with wearing orthotics, the ideal technical goal in this field is to achieve "positional adaptive adjustment" of the orthotic pressure: that is, when the patient is in a sitting or standing position or other daily activity position, the orthotic can provide maximum tightness to maintain the corrective force line; while when the patient enters a lying position, the device can automatically and moderately loosen to a certain extent to relieve chest and abdominal pressure. At the same time, this loosening must be limited and still maintain a basic mechanical locking state to prevent the orthotic from completely disengaging and losing its basic protective function.

[0004] Existing commercially available products, such as the standard Boston scoliosis brace manufactured by Boston Orthotics & Prosthetics, generally use conventional nylon Velcro straps or fixed one-way mechanical buckles to connect the anterior and posterior armor plates. The limitation of this existing mechanical structure lies in its single state: once the buckle or strap is locked, the distance between the two armor plates is fixed. When the patient changes from a sitting to a lying position, this static connection structure cannot sense changes in surface pressure and make a mechanical yielding response. To relieve pressure, the patient must manually completely unfasten the buckles or tear the straps; once manually unfastened, the orthosis loses its locking restraint and cannot provide any orthopedic support during sleep. This structure cannot simultaneously address lying comfort and basic locking requirements. Therefore, there is an urgent need to design an adjustable scoliosis orthosis brace that can adaptively and dynamically adjust its tightness based on changes in body position. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a scoliosis orthosis with adjustable correction degree, which enables adaptive dynamic adjustment of the orthosis's restraint force based on changes in the patient's body position.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A scoliosis orthosis with adjustable correction degree includes a main body. A plurality of fixed locking seats and a plurality of adjustable locking seats are fixedly connected at intervals on the front surface of the main body, with each fixed locking seat and adjustable locking seat corresponding to the others. A connecting strap is provided between each corresponding fixed locking seat and adjustable locking seat. One end of the connecting strap passes through the interior of the fixed locking seat, and the other end of the connecting strap is fixedly connected to a locking strap end block. Each adjustable locking seat has a first cavity inside, and a support plate is fixedly connected inside each first cavity. Each support plate has a movable gap, and a transmission lever passing through the movable gap is rotatably connected to each support plate. A first push-pull rod passing through the first cavity is fixedly connected to one side of each locking strap end block, and the end of the first push-pull rod away from the locking strap end block is rotatably connected to one end of the transmission lever. A pneumatic assembly for driving the transmission lever to rotate is fixedly connected to one side of each adjustable locking seat, and the power output end of the pneumatic assembly passes through the first cavity and is rotatably connected to the other end of the transmission lever.

[0007] The technical principles of the above solution are as follows: When a patient wears this orthosis, the weight of the torso exerts physical pressure on the back as the patient changes position from sitting to lying down. This pressure causes a sharp increase in fluid pressure inside the pneumatic components, and the gas expansion force drives the power output end of the pneumatic components to produce a linear displacement. The power output end pushes one end of the transmission lever, forcing the entire transmission lever to rotate around the rotational connection point on the support plate. Under this mechanical linkage, the other end of the transmission lever pushes the first push-pull rod and the locking strap end block to slide a fixed distance away from the interior of the adjustable locking seat. Since the locking strap end block is fixedly connected to the connecting strap, this outward sliding displacement effectively releases the tension of the connecting strap between the fixed locking seat and the adjustable locking seat, thereby achieving mechanical expansion of the orthosis's circumference while maintaining the basic anti-disengagement locking mechanism.

[0008] The above approach has the following beneficial effects: 1. This solution constructs a stable and reliable basic mechanical restraint framework by setting up one-to-one corresponding fixed locking seats, adjustable locking seats and connecting straps, ensuring that the patient's trunk is provided with strong structural support and positive corrective force in daily sitting or standing or other routine orthopedic states.

[0009] 2. This solution cleverly introduces a physical linkage mechanism between pneumatic components and transmission levers, transforming the unavoidable gravitational pressure on the body while lying down into pneumatic driving force, achieving purely physical adaptive release without electronic sensors or external power supply. This structure effectively solves the pain point of chest and abdominal tightness caused by conventional braces when patients are lying flat, significantly improving patients' sleep comfort at night and long-term wearing compliance.

[0010] Furthermore, the pneumatic assembly includes an airbag fixedly connected to the inner surface of the main body and several pneumatic actuators fixedly connected to one side of the adjustable lock seat. Each pneumatic actuator has a second cavity inside, and a piston is slidably fitted inside each second cavity. A second push-pull rod is fixedly connected to one side of each piston, and the end of the second push-pull rod away from the piston is the power output end. The airbag is connected to a main air pipe, and the end of the main air pipe away from the airbag is connected to several branch air pipes. Each branch air pipe corresponds to a pneumatic actuator, and each branch air pipe is connected to the corresponding second cavity.

[0011] Beneficial effects: The internal fluid conduction path and actuation structure of the pneumatic components were clarified. Utilizing an airbag as a large-area pressure sensing source, combined with the corresponding diversion structure of the branch air ducts, ensures that pressurized gas is synchronously and evenly distributed to each pneumatic actuator. This design ensures that multiple adjustable locking seats can smoothly and synchronously perform mechanical release actions, effectively avoiding transmission jamming caused by uneven force on one side.

[0012] Furthermore, springs are installed inside the second cavity, with both ends of the springs fixedly connected to the bottom wall of the second cavity and the other side surface of the piston, respectively.

[0013] Beneficial effects: Provides stable mechanical reset potential energy for the piston. The fixed connection at both ends of the spring ensures its structural stability when it is forcibly expanded by gas in the second cavity, effectively transmitting the tensile reset force. When the patient stands up and the external physical pressure of the airbag disappears, the spring releases elastic potential energy, actively pulling the piston back to its initial position, and then pulling back the transmission lever in the opposite direction, realizing the automatic restoration of the orthotic restraint state.

[0014] Furthermore, magnets are fixedly connected to the sidewalls of the first cavity, and the magnets are located next to the first push-pull rod. The surface of the transmission lever near the end of the first push-pull rod is in contact with the surface of the magnet.

[0015] Beneficial effects: A normal static magnetic locking mechanism was established. In the non-lying, pneumatically untriggered state, the physical attraction of the magnet to the transmission lever maintains the shortest fastening stroke of the connecting belt, effectively preventing accidental slippage of the mechanical structure due to the patient's daily body twisting, and improving the locking reliability of the adjustable locking seat under force.

[0016] Furthermore, each end of the transmission lever near the first push-pull rod is provided with an adsorption surface adapted to the magnet.

[0017] Beneficial effects: It effectively increases the physical contact area between the transmission lever and the magnet, optimizes the magnetic force conduction performance, and makes the static adsorption and locking under normal conditions more stable.

[0018] Furthermore, the distance between the first push-pull rod and the support plate is smaller than the distance between the second push-pull rod and the support plate.

[0019] Beneficial effects: The asymmetric lever principle enables mechanical amplification of pneumatic thrust. The pneumatic components only need to output a small driving force to convert it into a large mechanical stripping force sufficient to overcome the magnetic attraction at one end of the first push-pull rod. This design significantly reduces the pneumatic trigger threshold, ensuring a sensitive release response even for lighter-weight adolescent patients.

[0020] Furthermore, each side wall of the pneumatic actuator is provided with an air inlet and an exhaust outlet. The diameter of the air inlet is larger than that of the exhaust outlet. Both the air inlet and the exhaust outlet are connected to the interior of the second cavity and are connected to the corresponding branch air guide pipe.

[0021] Beneficial effects: A differentiated control structure for aerodynamic flow rate was constructed. The air intake ensures that high-pressure airflow rapidly enters the second cavity during the moment of lying down, achieving an agile release response; the exhaust duct generates a fluid throttling buffer effect during repositioning and exhaust, limiting the gas backflow speed, making the recovery process smooth and gentle, and avoiding mechanical impact on the torso from instantaneous tightening.

[0022] Furthermore, an intake check valve is fixedly connected inside the intake duct, and an exhaust check valve is fixedly connected inside the exhaust duct.

[0023] Beneficial effects: It strictly regulates the unidirectional conduction path of internal fluids, eliminating disorderly backflow of gas in the intake and exhaust ducts. It ensures that the two pneumatic cycle processes of "high-flow-rate intake triggering" and "high-flow-rate exhaust suction" operate strictly independently and without interference.

[0024] Furthermore, a number of first ventilation holes are provided on the front surface of the main body, and a number of second ventilation holes are provided on the rear surface of the main body.

[0025] Beneficial effects: It establishes a physical ventilation and heat dissipation path that runs through the front and back of the main body, which facilitates the rapid removal of heat and sweat from the patient's torso and improves the breathability of rigid orthotics when worn close to the body for a long time.

[0026] Furthermore, the airbag has a mesh-like structure, and the second ventilation holes are all located within the gaps of the mesh-like structure.

[0027] Beneficial effects: By cleverly utilizing the natural gaps in the airbag's original mesh-like topology, a physical exhaust channel for the second ventilation hole is directly created. While ensuring that the airbag has a sufficiently large pressure-triggered area, it does not interfere with ventilation and heat dissipation on the back of the main body, perfectly balancing the dual needs of pressure sensitivity and back breathability and sweat wicking.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The following detailed description illustrates the specific implementation method: Example 1

[0034] As attached Figure 1 and attached Figure 2 As shown, an adjustable scoliosis orthosis includes a main body 1 with an encircling structure. Structurally, several fixed locking seats 5 and several adjustable locking seats 7 are bolted together on the front surface of the main body 1. The fixed locking seats 5 and adjustable locking seats 7 are arranged in a one-to-one correspondence. A nylon connecting strap 6 spans between each corresponding fixed locking seat 5 and adjustable locking seat 7. To accommodate the orthodontic needs of different patients, the fixed locking seat 5 has a manually adjustable multi-position structure. One end of the connecting strap 6 is inserted into and anchored to this multi-position adjustment structure to establish the initial basic degree of correction. The other end of the connecting strap 6 has a locking end block 601 integrally molded by injection molding.

[0035] Combined with appendix Figure 5 As shown, each adjustable lock seat 7 has a first cavity 704 inside. A support plate 701 is adhered to the inner wall of each first cavity 704, and each support plate 701 has a movable gap. A transmission lever 702 passing through this gap is hinged to each support plate 701 via a pin. Furthermore, a first push-pull rod 602 is embedded in the side of the lock band end block 601 near the adjustable lock seat 7. The first push-pull rod 602 extends into the first cavity 704, and the end of the first push-pull rod 602 away from the lock band end block 601 is hinged to one end of the corresponding transmission lever 702. A pneumatic assembly for driving the transmission lever 702 is fastened to one side of each adjustable lock seat 7 with screws. The power output end of the pneumatic assembly extends into the first cavity 704 and is hinged to the other end of the corresponding transmission lever 702.

[0036] Combined with appendix Figure 4 With appendix Figure 5 As shown, the pneumatic assembly includes an airbag 3 heat-bonded to the inner back surface of the main body 1, and pneumatic actuators 8 attached to one side of the adjustable lock seat 7. Each pneumatic actuator 8 has a second cavity 808 inside. A piston 806 is slidably fitted into each second cavity 808. A second push-pull rod 807 made of metal is welded to one side of each piston 806. The end of the second push-pull rod 807 away from the piston 806 is the power output end that passes through the first cavity 704. Regarding airflow transmission, a main air pipe 4 is sleeved on the top connector of the airbag 3. The end of the main air pipe 4 away from the airbag 3 branches out through a three-way connector to several branch air pipes 9 made of silicone material. Each branch air pipe 9 corresponds to a pneumatic actuator 8 and is connected to its corresponding second cavity 808.

[0037] The specific implementation process is as follows: In the initial wearing scenario, the patient inserts the connecting strap 6 into the appropriate position inside the fixing lock seat 5 according to different degrees of orthodontic needs. This operation completes the setting of the basic degree of orthodontic treatment.

[0038] When the patient is in a normal sitting or leaning back position, the force on the back is distributed, and the increase in fluid pressure generated inside the airbag 3 is small and insufficient to overcome static friction to drive the pneumatic components, thus ensuring stable fastening under normal conditions.

[0039] When the patient enters the nighttime sleep stage, they transition from a sitting to a completely supine position. The chest and abdomen experience static high pressure and suffocation. At this time, the weight of the torso is distributed and continuously compressed over a large area, compressing the air sac 3 on the inner surface of the main body 1. The air sac 3 deforms rapidly, and the internal fluid pressure instantly exceeds the static threshold. High-pressure gas is rapidly diverted through the main trachea 4, simultaneously flowing into each of the second cavities 808. Under the strong pushing force of fluid expansion, the piston 806 overcomes static friction and slides away from the branch trachea 9, causing the second push-pull rod 807 to produce a linear displacement. The second push-pull rod 807 pushes the transmission lever 702, forcing the transmission lever 702 to rotate around the pin on the support plate 701. In conjunction, the transmission lever 702 pushes the first push-pull rod 602 and the locking strap end block 601 to slide a fixed distance away from the interior of the first cavity 704. This outward mechanical action effectively releases the tension of the connecting strap 6, achieving the goal of synchronous physical expansion and decompression of the thoracic cavity while maintaining a mechanical closed loop. This action effectively relieves the pressure on the chest cavity during sleep at night, significantly enhancing the patient's sleep comfort while maintaining the mechanical connection and preserving the basic orthopedic restraint.

[0040] Example 2

[0041] As attached Figure 1 Appendix Figure 2 and appendix Figure 5 As shown, the difference from Embodiment 1 is that: Neodymium iron boron magnets 703 are embedded and bonded to the inner wall of the first cavity 704. The magnets 703 are all located beside the first push-pull rod 602, and the end of the transmission lever 702 near the magnet 703 is milled with a flat adsorption surface adapted to the magnet 703. The distance between the first push-pull rod 602 and the support plate 701 is less than the distance between the second push-pull rod 807 and the support plate 701; that is, the length from the hinge point of the support plate 701 and the transmission lever 702 to the end of the transmission lever 702 near the first push-pull rod 602 is less than the length to the other end.

[0042] In addition, as attached Figure 5 As shown, each of the second cavities 808 is fitted with a helical spring 805. The two ends of the spring 805 are respectively engaged with the side wall of the second cavity 808 and the side surface of the piston 806 away from the second push rod 807.

[0043] The specific implementation process is as follows: During the normal orthopedic phase of daily sitting and standing, the magnet 703 tightly adheres to the adsorption surface of the transmission lever 702, locking the position of the transmission lever 702 and preventing the connecting strap 6 from accidentally loosening due to twisting during the patient's daily activities.

[0044] When the patient lies flat, high-pressure gas enters the second cavity 808 and pushes the piston 806. As the piston 806 slides, it forcibly stretches the spring 805, causing the spring 805 to store elastic potential energy. Due to the offset setting of the hinge point of the support plate 701, the initial thrust applied by the second push-pull rod 807 to the long end of the transmission lever 702 is mechanically amplified at the short end of the transmission lever 702 near the first push-pull rod 602, transforming it into a larger pushing force sufficient to overcome the static attraction force of the magnet 703. This causes the transmission lever 702 to rotate, completing the release. This design allows for the release action to be triggered with relatively low air pressure.

[0045] Example 3

[0046] As attached Figure 1 As shown, the difference from Embodiment 2 is that the pneumatic actuator 8 has air inlet duct 801 and exhaust duct 802 respectively formed by opening holes in the side walls, as shown in the attached figure. Figure 5 As shown, the diameter of the intake duct 801 is larger than the diameter of the exhaust duct 802, and both the intake and exhaust ducts are connected to the interior of the second cavity 808 and to the corresponding branch air guide pipe 9. To control the flow direction, an intake check valve 803 is installed inside the intake duct 801, and an exhaust check valve 804 is installed inside the exhaust duct 802.

[0047] As attached Figure 2 and attached Figure 3 As shown, the front surface of the main body 1 has several circular first vent holes 2, and the rear surface of the main body 1 has several circular second vent holes 10. The airbag 3 has a mesh structure, and the second vent holes 10 are all projected and exposed in the gaps of the mesh structure.

[0048] The specific implementation process is as follows: The moment the object lies down, the high-pressure gas pushes open the valve disc of the intake one-way valve 803 and enters each of the second cavities 808 through the intake passage 801, achieving immediate release.

[0049] When the patient stands up, the pressure of the torso on the airbag 3 disappears. To overcome the resistance of the human torso expanding outward, each connecting strap 6 is tightened synchronously to the preset base position. The tension released by the contraction of the spring 805 alone may not provide sufficient repositioning traction.

[0050] At this point, the back airbag 3 expands due to the elastic memory of its material, creating a negative pressure within the airbag 3 and the main air tube 4. The exhaust one-way valve 804 is opened by suction, forcing the gas in the second cavity 808 to flow out only through the small-diameter exhaust channel 802. As the internal gas passes through the narrow cross-section of the small-diameter exhaust channel 802, its flow velocity increases. According to Bernoulli's principle, this increase in flow velocity generates a localized dynamic low-pressure suction force in front of the piston 806.

[0051] The negative pressure generated by the rebound of the airbag 3, combined with the low pressure generated by the increased flow rate, forms a compound pneumatic suction force. This suction force, in conjunction with the pulling force of each spring 805, draws each piston 806 towards the exhaust port 802, thereby pushing it back to the bottom of the transmission lever 702 via the second push-pull rod 807. This compound force overcomes the outward expansion force of the torso, pulling the top of the transmission lever 702 back to the magnet 703 and re-attaching and locking it, restoring it to the initially set secure position.

[0052] Furthermore, during wear, the airbag 3 not only serves as the power source for the airway components, but its internal gas and flexible material also act as a physical cushion, effectively dispersing the rigid pressure on the back and improving the patient's comfort during prolonged close-fitting wear. Simultaneously, the first vent 2 on the front of the main body 1 and the second vent 10 on the rear establish an airflow path, while the mesh structure of the airbag 3 avoids the exhaust path of the second vent 10, ensuring unobstructed heat dissipation on the back.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
