Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a scoliosis orthosis with adjustable orthopedic pressure and its installation method. Background Technology

[0002] Scoliosis is a common three-dimensional spinal deformity, with a particularly high incidence among adolescents. It not only affects posture but can also compress internal organs and impair physiological function in severe cases. In non-surgical treatment, orthotics is the mainstream intervention method. Its core principle is to apply directional pressure to the convex side of the scoliosis, inhibiting its growth and promoting the development of the concave side, thereby achieving the corrective effect.

[0003] Existing orthotics mostly use rigid overall support or airbag pressurization, which has the following shortcomings: First, the precision of the orthodontic pressure adjustment area is low, and it is impossible to apply pressure differently to different areas of the convex side; second, the orthodontic pressure is difficult to control, and excessive pressure can easily cause patient discomfort or insufficient pressure can affect the correction effect; third, it is impossible to flexibly adjust the pressure area and intensity according to the patient's spinal convexity and correction stage.

[0004] Furthermore, the fit and comfort of existing devices need improvement. An orthosis often needs to be adapted to patients of different ages, body sizes, and scoliosis patterns, but traditional designs lack modular pressure adjustment units, making it difficult to achieve personalized fit and resulting in reduced patient compliance. Summary of the Invention

[0005] The purpose of this invention is to provide a scoliosis orthosis with adjustable orthopedic pressure and an installation method. Through modular design, the orthopedic pressure on the convex side of the spine can be controlled, and it can be flexibly adjusted according to the patient's feelings and needs, thereby improving the correction effect and wearing comfort.

[0006] To achieve the above objectives, this invention discloses a scoliosis orthosis with adjustable orthotic pressure and its installation method, comprising a force-applying device, an orthosis body, and Velcro. The Velcro is connected to both ends of the orthosis body. The force-applying device is installed on the convex side of the orthosis. The force-applying device includes a screw, a nut, a spring, a thin plate, and a washer. One end of the screw is connected to the convex side of the orthosis. The screw passes through the washer and the thin plate in sequence. The spring is sleeved on the screw and located between the washer and the thin plate. The nut is installed on the end of the screw that passes through the thin plate.

[0007] Preferably, the thin sheet has a plurality of through holes, which are distributed in two concentric circles.

[0008] Preferably, the pad has several through holes II of the same size as the convex side area and thin sheet of the orthosis, and the positions of the through holes II on the pad correspond one-to-one with the positions of the through holes III in the convex side area of ​​the orthosis.

[0009] Preferably, both the sheet and the pad are made of medical-grade silicone material, and the pad is larger than the sheet.

[0010] Preferably, the screw is fixed to the convex side of the orthosis by welding or threading.

[0011] Preferably, the nut is a wing nut, and the surface of the nut is provided with anti-slip texture.

[0012] Preferably, a method for installing a scoliosis orthosis with adjustable orthotic pressure includes the following steps: Step S1: Select a thin film with an appropriate diameter based on the size of the convex region of the patient's spine; Step S2: Fix the pad to the preset position on the convex side of the orthosis with four screws, ensuring that the through hole two on the pad corresponds to and is flat with the through hole three on the convex side of the orthosis. Step S3: Pass one end of the screw through the orthotist and fix it to the corresponding through hole two of the washer, ensuring that the screw is perpendicular to the surface of the washer; Step S4: Nest springs into the screws one by one, and then pass the screws through the corresponding through holes of the thin sheet; Step S5: Install the nut on the end of the screw, keeping the spring uncompressed in the initial state; Step S6: After wearing the orthosis, adjust the nuts at each through hole according to the correction needs of each area of ​​the convex side of the spine: screw the nut in clockwise, the spring is compressed and generates elastic force, which is transmitted to the convex side of the spine through the washer; according to the orthopedic pressure requirements, such as through pressure sensor monitoring or based on patient feedback, control the screw depth of the nut so that the orthopedic pressure in each area reaches the preset value. Step S7: During the correction process, based on the review results, dynamically adjust the orthopedic pressure distribution by adjusting the nuts, or replace the springs with different elastic coefficients to adapt to changes in the correction stage.

[0013] Therefore, the adjustable-pressure scoliosis orthosis device and its installation method provided by the present invention have the following advantages over the prior art: 1. Zoned pressure application: Through the design of small holes distributed in two rings on the inner and outer sides of the thin sheet, the orthopedic pressure can be adjusted independently for different areas of the convex side of the spine, so as to achieve differentiated pressure and adapt to the complex shape of the convex side of the spine.

[0014] 2. Controllable and adjustable orthopedic pressure: The spring compression can be controlled by adjusting the installation depth of the nut. Combined with the selection of springs with different elastic coefficients, the orthopedic pressure can be adjusted according to the patient's feelings.

[0015] 3. Highly personalized and adaptable: Thin sheets of different diameters can be replaced to fit different sizes of convex areas of the spine, and the pressure components at each small hole can be adjusted independently, dynamically adjusting the orthopedic pressure distribution according to the patient's needs at each stage of correction.

[0016] 4. Simple structure and easy operation: It adopts a modular combination of screws, nuts and springs, which makes installation and disassembly convenient. Patients or medical staff can quickly adjust the orthodontic pressure without complicated tools.

[0017] 5. Safe and reliable materials: Medical-grade silicone and other biocompatible materials are selected to ensure safety and durability for long-term wear and reduce the risk of skin irritation. Attached Figure Description

[0022] Similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0024] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0026] Example 1 like Figures 1-6 As shown, this invention provides a scoliosis orthosis with adjustable orthotic pressure, including a force-applying device 5, an orthosis body 6, and Velcro 7. The orthosis body 6 serves as the main support structure and force-applying base, used to wrap around the torso and provide basic fixation. Pre-set small holes on its convex side are used to install the core force-applying device 5. The Velcro 7 is used to achieve quick wearing and overall fixation of the orthosis, and can also provide auxiliary fine-tuning of the wrapping properties.

[0027] The force application device 5 is the core of achieving precise orthodontic treatment, specifically including screw 1, nut 2, spring 3, thin plate 4, and washer 8. One end of screw 1 is fixed to the convex side of the orthodontic device via a threaded connection through washer 8. A medical-grade stainless steel screw with a length of 3-8cm and a diameter identical to the through hole is selected to ensure connection strength and meet load-bearing and corrosion resistance requirements. As the core load-bearing and transmission shaft, it provides a stable installation foundation and precise guidance for the entire device.

[0028] Spring 3 is nested on screw 1. It is a medical stainless steel spring with an elastic coefficient of 10-20 N / mm and a free length of 1-3 cm. As the core force source, the rebound force generated after compression is the direct source of orthopedic pressure, while providing cushioning to improve comfort. By selecting springs with different elastic coefficients, different orthopedic pressure requirements can be adapted. Its known elastic coefficients allow the pressure to be quantitatively controlled.

[0029] Thin plate 4 is made of 1.5mm thick medical-grade silicone material and has two rings of through holes 9, with 15-20 holes in each ring, arranged in an alternating pattern to avoid blind spots in the superposition of orthopedic pressure. Its diameter is 10-20cm and can be replaced according to the size of the convex side area of ​​the patient's spine. Thin plate 4 serves as a pressure distribution plate and a carrier for zoned adjustment, integrating the point forces of multiple springs into uniform surface pressure, and allowing independent fine-tuning of the force application unit corresponding to each through hole 9, so as to achieve true zoned pressure application and personalized adaptation.

[0030] The spacer 8 is located between the orthotine body 6 and the thin plate 4. It serves to strengthen the foundation, disperse stress, and prevent damage to the body. At the same time, it acts as a universal installation platform and adapter to ensure that thin plates of different sizes can be installed flat. The spacer 8 is larger than the thin plate 4.

[0031] Nut 2 is a wing-shaped nut with anti-slip texture on the surface. It is installed on the end of screw 1 through the through hole 9 of thin plate 4. It serves as a pressure regulator and locking device. The compression of spring 3 is controlled by the screwing depth (compression range 0.3-2cm), thereby precisely controlling the orthopedic pressure applied to the convex side of the spine. Its user-friendly design makes it easy to operate by hand.

[0032] The entire system, through the precise coordination of its components, achieves zoned, adjustable, dynamic, and comfortable correction of pressure on the convex side of the spine.

[0033] A method for installing a scoliosis orthosis with adjustable orthotic pressure includes the following steps: Step S1: Select a thin film 4 with an appropriate diameter based on the size of the convex side region of the patient's spine; Step S2: Fix the pad to the preset position on the convex side of the orthodont using four screws 1, ensuring that the through hole 2 10 on the pad 8 corresponds to and is flat with the through hole 3 11 in the convex side area of ​​the orthodont. Step S3: Pass one end of screw 1 through the orthotist and fix it to the corresponding through hole 10 of washer 8, ensuring that the screw is perpendicular to the surface of washer 8. Step S4: Nest springs 3 into screw 1 in sequence, and then pass screw 1 through the corresponding through hole 9 of thin plate 4; Step S5: Install nut 2 on the end of screw 1, keeping spring 3 uncompressed in the initial state; Step S6: After wearing the orthosis, adjust the nuts 2 at each through hole according to the correction needs of each area of ​​the convex side of the spine: screw the nuts 2 in clockwise, the spring 3 is compressed and generates elastic force, which is transmitted to the convex side of the spine through the washer 8; according to the correction pressure requirements, such as through pressure sensor monitoring or based on patient feedback, control the screw depth of the nuts 2 so that the correction pressure in each area reaches the preset value. Step S7: During the correction process, based on the review results, dynamically adjust the orthopedic pressure distribution by adjusting nut 2, or replace springs with different elastic coefficients to adapt to changes in the correction stage.

[0034] This invention employs the above-mentioned adjustable orthopedic pressure scoliosis orthosis and installation method. Through modular design, it achieves control of orthopedic pressure on the convex side of the spine, and can be flexibly adjusted according to the patient's feelings and needs, thereby improving the correction effect and wearing comfort.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
