Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a 3D-printed scoliosis correction brace and a method for manufacturing the correction brace. Background Technology

[0002] In recent years, scoliosis has become one of the major health threats among adolescents. Wearing a corrective brace is a core method of scoliosis rehabilitation and requires long-term use to achieve continuous correction. Currently, most mainstream scoliosis corrective braces are made from traditional materials such as rubber and TPE using standardized models, providing only basic physical support. These braces have two major problems: First, insufficient personalized fit; standardized production methods cannot accurately conform to the spinal curvature characteristics of different patients, leading to uneven distribution of corrective force and affecting rehabilitation outcomes. Second, limited functionality; existing braces rely solely on structural support for physical correction, lacking the integration of traditional Chinese medicine meridian theory and drug treatment methods, and failing to improve overall efficacy through regulating organ function and improving local blood circulation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a 3D printed scoliosis correction brace that can conform to the complex spinal curve and, in combination with traditional Chinese medicine poultices, stimulate the spinous processes of the spine to improve the correction effect of scoliosis.

[0026] The present invention also provides a method for manufacturing a corrective brace, for producing a 3D-printed scoliosis corrective brace as described above, comprising the following steps:

[0027] A three-dimensional model of the patient's spine is obtained, and the spinal curve features are determined based on the three-dimensional model;

[0028] Based on the spinal curve characteristics and the positioning requirements of the medicated dressing area, a model of the brace body is generated using 3D design software, and mounting holes are set on the medicated dressing area.

[0029] The support body is manufactured using 3D printing technology;

[0030] Insert the medicated dressing device into the mounting hole.

[0031] The step of obtaining the three-dimensional model of the patient's spine includes:

[0032] The patient's spine was scanned using medical imaging equipment to obtain tomographic image data containing the locations of the spinous processes of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra. A three-dimensional model of the spine was then reconstructed using image processing algorithms.

[0033] The positions of the spinous processes of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra are marked on the three-dimensional model. Centered on each spinous process, a first medicated dressing area, a second medicated dressing area, and a third medicated dressing area are respectively set at a horizontal distance of 4-6 cm on both sides of the spine. The corresponding areas of the first medicated dressing area, the second medicated dressing area, and the third medicated dressing area form mounting hole structures on the brace body model.

[0034] As an improvement to the above solution, the step of obtaining a three-dimensional model of the patient's spine includes:

[0035] The patient's spine was scanned using medical imaging equipment to obtain tomographic image data containing the locations of the spinous processes of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra. A three-dimensional model of the spine was then reconstructed using image processing algorithms.

[0036] The positions of the spinous processes of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra are marked on the three-dimensional model. Centered on the marked positions of each spinous process, a first medicated application area, a second medicated application area, and a third medicated application area are respectively set on both sides of the spine. The corresponding areas of the first medicated application area, the second medicated application area, and the third medicated application area form mounting hole structures on the brace body model.

[0037] As an improvement to the above solution, the step of inserting the medicated dressing device into the mounting hole includes:

[0038] Prepare the shell and pull-out shell, and prepare the medicine package;

[0039] Place the medicine pack inside the pull-out case and secure the medicine pack with the movable frame;

[0040] Insert the pull-out shell into the housing, flip the cover over and fix it to the side plate of the housing;

[0041] Insert the housing into the mounting hole and tighten it.

[0042] Implementing this invention has the following beneficial effects:

[0043] This invention relates to a 3D-printed scoliosis correction brace comprising a brace body and a medicated dressing device. The brace body is 3D-printed based on a patient's spinal model, allowing for a design that is tailored to the individual spinal anatomy. This solves the problem of traditional standardized braces failing to conform to complex spinal curves, achieving precise distribution of corrective force along the physiological curvature of the spine. The patient's spinal model has at least two first, second, and third medicated dressing zones on either side of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra, respectively. These zones are precisely installed on both sides of the patient's spine, aligning with the pathway of the Bladder Meridian of Foot Taiyang. By incorporating a medicated dressing device containing a hot compress pack of traditional Chinese medicine into these zones, the meridian-activating and blood-activating effects of the medicine, along with the heat stimulation, can synergistically achieve a dual effect of "external brace correction + internal meridian regulation," promoting the recovery of muscle function on both sides of the spine and thus improving the scoliosis correction effect.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0054] See Figure 1 and Figure 2 This invention discloses a 3D-printed scoliosis correction brace, comprising a brace body 1. The brace body 1 is 3D printed based on a patient's spine model 4. This three-dimensional model originates from medical imaging scan data of the patient's spine 4 and, after reconstruction, accurately reflects the physiological curvature and anatomical characteristics of the individual's spine 4. Through the personalized design of 3D printing, the inner surface of the brace body 1 can closely conform to the scoliosis shape of the patient's spine 4, so that the corrective force is evenly distributed on both sides of the spine 4. This avoids the problems of excessive local pressure or insufficient corrective force caused by the fixed shape of traditional standardized braces, thereby improving wearing comfort and the accuracy of the corrective effect.

[0055] The patient's spinal model includes the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra. The brace body 1 has at least two first medicated dressing areas 31 symmetrically arranged on both sides corresponding to the 7th thoracic vertebra, at least two second medicated dressing areas 32 symmetrically arranged on both sides corresponding to the 11th thoracic vertebra, and at least two third medicated dressing areas 33 symmetrically arranged on both sides corresponding to the 2nd lumbar vertebra. The first, second, and third medicated dressing areas 31, 32, and 33 correspond to the acupoints of the Bladder Meridian of Foot Taiyang (BL23), namely, the Diaphragm Shu (BL17), Spleen Shu (BL20), and Kidney Shu (BL23). Their symmetrical layout is based on traditional Chinese medicine meridian theory, ensuring that the heat from the medication can act synchronously on the unbalanced muscle groups on both sides of the spine. Each of the first, second, and third medicated dressing areas 31, 32, and 33 has mounting holes 11 for detachably mounting the medicated dressing device 2.

[0056] The 3D-printed scoliosis correction brace also includes a medicated dressing device 2. The medicated dressing device 2 includes a housing 21, which is detachably disposed within the mounting hole 11, allowing the patient to install or remove it as needed. A medicated pack 24 is detachably disposed within the housing 21, which contains a heating mechanism 23 capable of heating the medicated pack 24. The medicated pack 24 contains traditional Chinese medicine powders such as Angelica sinensis, Achyranthes bidentata, and Cinnamomum cassia, which have the effect of promoting blood circulation and relieving muscle tension. The heating mechanism 23 within the housing 21 heats the medicated pack 24, allowing the medicinal components to penetrate the skin and reach the muscle tissue on both sides of the spine 4 at a suitable temperature. Simultaneously, the heat application promotes local blood circulation and relieves muscle tension. Compared with the shortcomings of existing braces that lack drug intervention, this invention uses a dual mechanism of "physical orthodontics + traditional Chinese medicine hot compress" to apply structural corrective force to the spine 4 while using traditional Chinese medicine and hot compress to stimulate the acupoints of the bladder meridian, regulate the function of internal organs, improve the circulation of qi and blood, thereby enhancing the response of the muscles on both sides of the spine 4 to the corrective force and further improving the scoliosis correction effect.

[0057] The beneficial effects of the embodiments of the present invention are as follows:

[0058] This invention relates to a 3D-printed scoliosis correction brace comprising a brace body 1 and a medicated dressing device 2. The brace body 1 is 3D-printed based on a patient's spinal model, allowing the brace body 1 to be designed based on the individual's spinal anatomy. This solves the problem that traditional standardized braces cannot conform to the complex curves of the spinal spine, achieving precise distribution of corrective force along the physiological curvature of the spinal spine. Furthermore, at least two first medicated dressing areas 31, two second medicated dressing areas 32, and two... are respectively provided on both sides of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra of the patient's spinal model. The third medicated application area 33, while the first medicated application area 31, the second medicated application area 32 and the third medicated application area 33 are precisely installed on both sides of the patient's spine 4. These areas are the pathway of the Bladder Meridian of Foot Taiyang. By setting the medicated application device 2 containing Chinese medicine hot compress packs in the first medicated application area 31, the second medicated application area 32 and the third medicated application area 33, the meridian-clearing and blood-activating effects of Chinese medicine and the stimulation of hot compress can be combined with physical correction to achieve the dual effect of "external bracing and internal meridian regulation", promote the recovery of muscle function on both sides of the spine 4, and thus improve the correction effect of scoliosis.

[0059] Specifically, the patient's spinal model includes the spinous processes of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra. The brace body has at least two first medicated application areas 31 symmetrically arranged on both sides corresponding to the 7th thoracic spinous process, at least two second medicated application areas 32 symmetrically arranged on both sides corresponding to the 11th thoracic spinous process, and at least two third medicated application areas 33 symmetrically arranged on both sides corresponding to the 2nd lumbar spinous process. That is, the first medicated application areas 31 correspond to the position of the 7th thoracic spinous process of the patient's spine 4, the second medicated application areas 32 correspond to the position of the 11th thoracic spinous process of the patient's spine 4, and the third medicated application areas 33 correspond to the position of the 2nd lumbar spinous process of the patient's spine 4. The area lateral to the spinous process of the 7th thoracic vertebra (first medicated area 31) corresponds to the Diaphragm Shu point, which is mainly used to treat stagnation of qi and blood; the area lateral to the spinous process of the 11th thoracic vertebra (second medicated area 32) corresponds to the Spleen Shu point, which is related to the regulation of spleen and stomach function; the area lateral to the spinous process of the 2nd lumbar vertebra (third medicated area 33) corresponds to the Kidney Shu point, which is related to the function of the kidneys and lumbar muscles.

[0060] By setting the first medicated application area 31, the second medicated application area 32, and the third medicated application area 33 at the corresponding positions of the spinous processes of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra, respectively, the herbal hot compress effect of the medicated application device 2 is precisely applied to different sections of the Bladder Meridian of Foot Taiyang, thereby achieving graded regulation of the functions of the internal organs and, in conjunction with the physical orthopedic force of the brace body 1, improving the imbalance of muscle tension on both sides of the spine 4 from the dual dimensions of "muscles and bones - internal organs".

[0061] See Figure 1The horizontal distance from the center of the mounting hole 11 in the first medicated application area 31 to the spinous process of the 7th thoracic vertebra is a, and the value of a ranges from 4cm to 6cm. Within this range, the mounting hole 11 can be accurately aligned with the path of the Bladder Meridian of Foot Taiyang. The distance lateral to the spinous process of the 7th thoracic vertebra is the Diaphragm Shu point (mainly for treating blood disorders); the horizontal distance from the center of the mounting hole 11 of the second medicated area 32 to the spinous process of the 11th thoracic vertebra is b, with a value ranging from 4cm to 6cm, and the distance lateral to the spinous process of the 11th thoracic vertebra is the Spleen Shu point (mainly for treating spleen and stomach diseases); the horizontal distance from the center of the mounting hole 11 of the third medicated area 33 to the spinous process of the 2nd lumbar vertebra is c, with a value ranging from 4.5cm to 5.5cm, slightly shorter than the horizontal distance of the spinous processes of the thoracic vertebrae, to ensure that this distance avoids the bony obstruction of the transverse processes of the lumbar vertebrae and ensures that the medicated device is in close contact with the medial edge of the erector spinae muscle, further improving the accuracy of the Kidney Shu point location, and the distance lateral to the spinous process of the 2nd lumbar vertebra is the Kidney Shu point (mainly for treating kidney deficiency and lower back pain). By limiting the mounting holes 11 of each medicated application area to the aforementioned horizontal distance range, it is possible to ensure that the herbal hot compress effect of the medicated application device 2 directly acts on the deep tissues of the acupoints of the bladder meridian. This allows the warming effect and drug penetration generated by the hot compress to specifically regulate the functions of the corresponding organs (such as regulating blood at the diaphragm point, strengthening the spleen at the spleen point, and tonifying the kidney at the kidney point) through the conduction pathway of acupoint-meridian-organ. At the same time, it improves the blood circulation and muscle tone balance of muscle groups such as the erector spinae muscles on both sides of the spine 4.

[0062] See Figure 2 The 3D-printed scoliosis correction brace also includes a pull-out shell 22, which is detachably inserted into the housing 21. The pull-out shell 22 has a placement slot 221 within it, where the medication pack 24 can be fixed. After the medication pack 24 is placed in the placement slot 221, it forms a detachable integrated unit with the pull-out shell 22, fitting into the internal space of the housing 21 via a plug-in structure. Due to the detachable design of the pull-out shell 22, the patient can remove it entirely from the housing 21 after each hot compress for individual cleaning and disinfection, preventing residual medication from contaminating the inside of the housing 21 or causing bacterial growth, significantly improving the hygiene of the brace. Furthermore, when the efficacy of the medication pack 24 decreases, the old medication pack 24 can be quickly removed and replaced with a new one simply by opening the pull-out shell 22, without needing to disassemble the entire brace body 1 or the medication application device 2, greatly improving ease of use.

[0063] See Figure 3The pull-out shell 22 includes a first base plate 222, a movable frame 223, and a fixed plate 224. The movable frame 223 is hinged to both sides of the first base plate 222 and can be rotated relative to the first base plate 222. When the movable frame 223 is upright, it can form the placement groove 221 with the first base plate 222. The fixed plate 224 is vertically arranged in the first base plate 222 near the side edge of the movable frame 223. The fixed plate 224 is perpendicular to the movable frame 223. When the movable frame 223 is upright, it can be fixed to the side of the fixed plate 224. When the movable frame 223 is flipped from a horizontal state to a vertical state, it and the first base plate 222 together form the placement groove 221 for accommodating the medicine pack 24. At this time, the movable frame 223 is fixed by cooperating with the fixing plate 224: the fixing plate 224 is vertically arranged on the side edge of the first base plate 222 near the movable frame 223 and is perpendicular to the movable frame 223. When the movable frame 223 is upright, it can be fixed to the side of the fixing plate 224 by a quick-release structure, thereby clamping the medicine pack 24 in the placement groove 221, preventing the medicine pack 24 from shifting during the hot compress process, and ensuring the accuracy of the position of the Chinese medicine hot compress.

[0064] The first base plate 222 has multiple first through holes 2221, which are honeycomb-shaped and communicate with the placement groove 221 and directly contact the medicine pack 24. The honeycomb-shaped through hole layout, through its dense pore structure, increases the heat conduction and drug penetration area between the medicine pack 24 and the skin. This allows the warming effect generated by the heated medicine pack 24 and the effective components of the traditional Chinese medicine to act evenly on the skin and deep tissues on both sides of the patient's spine 4 through the through holes, while avoiding heat accumulation or uneven drug release caused by a sparse through hole layout. Simultaneously, the dense distribution of the first through holes 2221 also generates frictional force on the sides of the medicine pack 24, further ensuring the stability of the medicine pack 24.

[0065] The upper part of the fixing plate 224, near the middle of the pull-out shell 22, has a concave arc-shaped corner 2241. The curved contour of the arc-shaped corner 2241 matches the side edge shape of the medicine pack 24. After the medicine pack 24 is placed in the placement slot 221, the medicine pack 24 can abut against the arc-shaped corner 2241. The arc-shaped corner 2241 reduces the local compressive stress on the medicine pack 24 through curved surface support, avoiding damage to the medicine pack 24 or leakage of drug powder due to rigid right-angle contact.

[0066] The movable frame 223 includes a hinge plate 2231, a top guard plate 2232, and a lower pressure plate 2233. The hinge plate 2231 is hinged to one side of the first base plate 222 via a pin or hinge seat, forming a flip-up connection structure. The top guard plate 2232 is vertically fixed to the side of the hinge plate 2231 away from the first base plate 222. When the movable frame 223 flips from a horizontal state to a vertical state, the top guard plate 2232 extends toward the center of the placement groove 221, forming the side limiting boundary of the placement groove 221. The lower pressure plate 2233 is connected to the side of the top guard plate 2232 away from the hinge plate 2231. The top guard plate 2232 extends toward the placement groove 221. When the movable frame 223 is erected, the lower pressure plate 2233 can abut against the medicine pack 24 downwards, thereby further fixing and limiting the medicine pack 24. At the same time, the lower pressure plate 2233 can squeeze the medicine pack 24, which, together with the heating process, can improve the drug penetration efficiency.

[0067] The hinge plate 2231 is provided with a connecting plate 2234, which protrudes vertically from the surface of the hinge plate 2231 and can swing with the hinge plate 2231. The connecting plate 2234 is provided with a fixing protrusion 2235, which protrudes horizontally from the surface of the connecting plate 2234. The side of the fixing plate 224 is provided with a fixing groove 2242 and a sliding groove 2243. The fixing groove 2242 communicates with the sliding groove 2243. The fixing groove 2242 is an arc-shaped groove, and its radius of curvature is adapted to the swing trajectory of the fixing protrusion 2235 when the movable frame 223 is flipped, ensuring that the fixing protrusion 2235 can slide smoothly along the arc-shaped trajectory. When the movable frame 223 flips from a horizontal to a vertical position, the fixing protrusion 2235 first slides along the straight track of the sliding groove 2243. When the movable frame 223 flips to the vertical position, the fixing protrusion 2235 falls exactly into the fixing groove 2242. The depth of the fixing groove 2242 is greater than the depth of the sliding groove 2243. When the movable frame 223 flips, the fixing protrusion 2235 can slide in the sliding groove 2243 and insert into the fixing groove 2242. Since the depth of the fixing groove 2242 is greater than that of the sliding groove 2243, the fixing protrusion 2235 forms a mechanical limit after being embedded in the fixing groove 2242, so that the movable frame 223 is stably fixed in the vertical position, thereby clamping the medicine pack 24 in the placement groove 221.

[0068] See Figure 2 and Figure 4The housing 21 includes an insertion slot 211 with a rectangular cavity matching the shape of the pull-out shell 22. The pull-out shell 22 can be inserted into the insertion slot 211 to fix it in place. The housing 21 also includes a flip cover 212, one side of which is hinged to one side of the insertion slot 211 via a hinge shaft. The flip cover 212 can be flipped relative to the insertion slot 211 and can cover it. When the flip cover 212 covers the insertion slot 211, its inner surface forms a tight seal with the top edge of the pull-out shell 22 to prevent heat loss during hot compress. The heating mechanism 23 is fixed in the flip cover 212 on the side near the insertion slot 211. Its position corresponds to the area of ​​the medicine pack 24 inside the pull-out shell 22. When the flip cover 212 is flipped closed, the heating mechanism 23 comes into contact with the medicine pack 24, and can uniformly heat the medicine pack 24 to a suitable temperature through heat radiation and conduction.

[0069] See Figure 4 and Figure 5 The housing 21 includes a second base plate 213, side plates 214 respectively disposed on both sides of the second base plate 213, and a rear plate 215 disposed on the rear side of the second base plate 213 and connected between the two side plates 214. The second base plate 213, the side plates 214, and the rear plate 215 form the insertion groove 211. The flip cover 212 is hinged to the rear plate 215. The inner sidewall of the side plate 214 is provided with a limiting groove 2141, which extends longitudinally. The pull-out shell 22 is provided with limiting strips 225 on both sides. When the pull-out shell 22 is inserted into the insertion groove 211, the limiting strips 225 can be inserted into the limiting groove 2141 to form a guiding and positioning structure. When the pull-out shell 22 is inserted into the insertion groove 211, the limiting strips 225 slide horizontally along the groove wall of the limiting groove 2141 until the pull-out shell 22 is completely inserted into the housing 21.

[0070] The flip cover 212 has spring-loaded buckles 2121 on both sides, and the side plate 214 has a locking hole 2142. The spring-loaded buckles 2121 can be fastened into the locking hole 2142. When the flip cover 212 is flipped to cover the insertion slot 211, the spring-loaded buckles 2121 are elastically deformed and locked into the locking hole 2142, forming a detachable locking structure to ensure that the flip cover 212 remains closed during hot compress. The second base plate 213 has multiple second through holes 2131. The second through holes 2131 are honeycomb-shaped and communicate with the insertion slot 211 and correspond to the position of the first through hole 2221. When the pull-out shell 22 is inserted into the insertion slot 211, the first through hole 2221 and the second through hole 2131 form a vertically connected pore channel, allowing the warm airflow generated by the heated medicine pack 24 and the volatile components of the traditional Chinese medicine to act evenly on the patient's skin surface through the double-layer honeycomb perforated structure.

[0071] Because the spinous processes of the thoracic and lumbar vertebrae differ in morphology and function, the spinous processes of the thoracic vertebrae are long and thin, arranged in an overlapping manner, and the surrounding muscles are thin and have low mobility. The medicated application area of ​​the thoracic vertebrae corresponds to the Diaphragm Shu (regulating qi and blood) and the Spleen Shu (strengthening the spleen and stomach), and stable stimulation is required to regulate the functions of the upper and middle jiao. On the other hand, the spinous processes of the lumbar vertebrae are short and wide, plate-like, and the surrounding muscles are thick and have high mobility. The medicated application area of ​​the lumbar vertebrae corresponds to the Kidney Shu (tonifying kidney qi), and lumbar movement is accompanied by the circulation of qi and blood in the meridians.

[0072] To ensure the effectiveness of the medicated dressing on both sides of the spinous processes of the thoracic vertebrae, please refer to [link / reference needed]. Figure 5 and 7The outer edges of the mounting holes 11 corresponding to the first and second medicated dressing areas 31 and 32 are provided with several mounting notches 111. The inner edges of the mounting holes 11 are provided with sliding grooves 112, which are annular and recessed into the edges of the mounting holes 11. The edges of the housing 21 of the medicated dressing device corresponding to the first and second medicated dressing areas 31 and 32 are provided with several locking blocks 216. The locking blocks 216 can be inserted into the mounting notches 111 and slide within the sliding grooves 112. When the medicated dressing device 2 corresponding to the first and second medicated dressing areas 31 and 32 is installed, and the housing 21 is installed in the mounting holes 11, the locking blocks 216 are first aligned with the mounting notches 111 and inserted. Then, by rotating the housing 21, the locking blocks 216 slide along the annular trajectory of the sliding grooves 112, finally locking into the locking position of the sliding grooves 112. The sidewall of the groove 112 is provided with anti-slip texture, preferably serrated or grid-like protrusions. The anti-slip texture increases the friction coefficient of the contact surface, preventing the locking block 216 from sliding within the groove 112, thereby achieving circumferential locking between the housing 21 and the mounting hole 11. The mounting holes 11 corresponding to the first medicated area 31 and the second medicated area 32 adopt a "rigid rotation locking" structure. Taking advantage of the small range of motion of the thoracic spine, a rigid connection is used to ensure stable contact between the medicated device 2 and the parathoracic muscles (such as the rhomboid muscles and the thoracic erector spinae muscles), allowing the medicinal properties generated after the medicine pack is heated to accurately act on acupoints such as the diaphragm and spleen points through the perforations.

[0073] To achieve a mobile application effect on both sides of the spinous processes of the lumbar vertebrae, see [link / reference]. Figure 6 and Figure 8 To address the characteristics of the lumbar spinous processes being "short, wide, thick, and plate-like" and the lumbar muscles (such as the psoas major and erector spinae lumbar segments) having a high degree of mobility, a flexible ring 26 is provided on the inner edge of the mounting hole 11 of the third medicated area 33. The flexible ring 26 can abut against the periphery of the housing 21 of the medicated device 2 corresponding to the third medicated area 33. Its elastic material (such as silicone) forms a movable abutment with the periphery of the housing 21, which on the one hand radially limits the position of the medicated device 2, and on the other hand allows the medicated device 2 to move within the mounting hole 11. A spring piece 25 is provided on the side of the mounting hole 11 of the third medicated area 33. The spring piece 25 is rotatably connected to the support body 1, and one end of the spring piece 25 can elastically abut against the housing 21 to generate axial abutment pressure on the medicated device 2. When the lumbar region flexes and extends, the elastic cooperation between the flexible coil 26 and the spring sheet 25 allows the medicated dressing device 2 to make moderate displacement. While ensuring that the medicated dressing device 2 adheres tightly to the skin, it avoids the restriction of lumbar spine movement by traditional rigid fixation, so as to adapt to the anatomical characteristics of the lumbar spine segment that is "highly mobile and easily deformable".

[0074] Specifically, the spring piece 25 includes a connecting section 251, an elastic section 252, and an abutting section 253. The connecting section 251 is rotatably connected to the outer wall of the support body 1 and can rotate relative to the support body 1. The elastic section 252 bends from the connecting section 251 first toward the side away from the support body 1 and then bends toward the side closer to the support body 1, forming an inverted "V" shaped structure. The elastic section 252 is elastic. The abutting section 253 is located on the side of the elastic section 252 away from the connecting section 251 and can abut against the housing 21. When installing the medicated dressing device 2 of the third medicated dressing area 33, first unscrew the spring piece 25 from the mounting hole 11 to expose the mounting hole 11, then insert the cylindrical part of the housing 21 into the mounting hole 11 so that the flexible ring 26 abuts against the circumference of the cylindrical part of the housing 21, and then screw the spring piece 25 into the mounting hole 11 so that the abutting section 253 can abut against the side of the housing 21 to form axial limitation.

[0075] Furthermore, the first base plate 222 and the second base plate 213 in the medicated dressing device 2 corresponding to the third medicated dressing area 33 are both made of shape memory alloy, and the side of the corresponding medicated pack that abuts against the first base plate 222 has an outwardly convex arc-shaped structure. The first base plate 222 and the second base plate 213 made of shape memory alloy form an arc shape under the action of body temperature. Combined with the outwardly convex arc-shaped medicated pack, this can increase the fit with the muscle and adapt to the movement generated by the muscle, thereby improving the efficiency of medicated dressing.

[0076] See Figure 9 The present invention also discloses a method for manufacturing a corrective brace, used to manufacture a 3D-printed scoliosis corrective brace as described above, comprising the following steps:

[0077] S01, Obtain a three-dimensional model of the patient's spine 4, and determine the curve features of spine 4 based on the three-dimensional model;

[0078] S02, based on the curve characteristics of the spine 4 and the positioning requirements of the medicated area 3, a model of the brace body 1 is generated using 3D design software, and mounting holes 11 are set on the medicated area 3;

[0079] S03, the support body 1 is manufactured using 3D printing technology;

[0080] S04, insert the medicated dressing device 2 into the mounting hole 11.

[0081] The fabrication method first involves scanning the patient's spine 4 using medical imaging equipment (such as CT or MRI) to obtain tomographic images containing the spinous processes of the thoracic and lumbar vertebrae. Image processing algorithms are then used to reconstruct a three-dimensional model that accurately reflects the individual's spinal 4 curvature. This step, based on the principle of precise anatomical positioning, allows subsequent brace design to be adapted to individualized parameters such as the patient's spinal 4 lateral curvature angle and vertebral rotation.

[0082] The 3D model was reverse engineered using 3D design software. The path of the Bladder Meridian of Foot Taiyang was marked on the virtual model of the brace body 1, and symmetrically distributed medicated application areas 3 were set at the locations of acupoints such as Geshu, Pishu, and Shenshu. A mounting hole 11 matching the housing 21 of the medicated application device 2 was made in the center of the medicated application area 3. This design integrates the theory of meridians in traditional Chinese medicine into the structural design of the brace, so that the positioning of the mounting hole 11 conforms to anatomical coordinates and is accurately aligned with key acupoints of the Bladder Meridian, laying the foundation for the meridian stimulation of subsequent hot compresses with traditional Chinese medicine, which is different from the existing brace layout that only opens holes for physical support.

[0083] By using 3D printing technologies such as fused deposition modeling (FDM) to manufacture a solid brace by stacking layers according to the model of the brace body 1, the inner surface of the brace body 1 can be precisely fitted with the three-dimensional curve of the patient's spine 4, ensuring that the corrective force is evenly distributed along the physiological curvature of the spine 4. Compared with traditional manual shaping or mold pressing processes, this significantly improves the anatomical fit between the brace and the human body.

[0084] After the heating mechanism 23 (such as a built-in electric heating element) of the medicated compress device 2 is connected to an external power source, it heats the Chinese medicine pack 24 (containing angelica, achyranthes, and other medicinal powders) inside the shell 21 to a suitable temperature, allowing the medicinal components to penetrate deep into the skin. At the same time, the warming effect stimulates the acupoints of the bladder meridian, achieving a synergistic therapeutic effect of "physical orthopedic force reshaping the spinal shape + Chinese medicine hot compress regulating qi and blood circulation".

[0085] The steps for obtaining the 4D model of the patient's spine include:

[0086] Medical imaging equipment was used to scan the patient's spine 4, and tomographic image data including the positions of the 7th thoracic vertebra, the 11th thoracic vertebra and the 2nd lumbar vertebra were obtained. The three-dimensional model of the spine 4 was reconstructed by image processing algorithms.

[0087] The positions of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra are marked on the three-dimensional model. A first medicated area 31, a second medicated area 32, and a third medicated area 33 are respectively set on both sides of the marked positions of the spine. The corresponding areas of the first medicated area 31, the second medicated area 32, and the third medicated area 33 form mounting hole 11 structures on the model of the brace body 1.

[0088] In the step of obtaining the three-dimensional model of the patient's spine 4, medical imaging equipment (such as CT or MRI) is used to perform tomographic scanning of the patient's spine 4, focusing on collecting regional data including the 7th thoracic vertebra, the 11th thoracic vertebra and the 2nd lumbar vertebra, which covers the thoracolumbar segment where scoliosis is common.

[0089] After marking the key spine 4 position on the 3D model, a first medicated application area 31, a second medicated application area 32, and a third medicated application area 33 are respectively set on both sides of the marked position of spine 4. This distance range ensures that the mounting holes 11 of each medicated application area are aligned with the main meridian of the Bladder Meridian of Foot Taiyang (such as the acupoints Geshu, Pishu, and Shenshu). The diameter of the mounting holes 11 matches the size of the housing 21 of the medicated application device 2.

[0090] The steps for obtaining a three-dimensional model of the patient's spine include:

[0091] The patient's spine was scanned using medical imaging equipment to obtain tomographic image data containing the locations of the spinous processes of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra. A three-dimensional model of the spine was then reconstructed using image processing algorithms.

[0092] The positions of the spinous processes of the 7th thoracic vertebra, the 11th thoracic vertebra, and the 2nd lumbar vertebra are marked on the three-dimensional model. Centered on the marked positions of each spinous process, a first medicated area 31, a second medicated area 32, and a third medicated area 33 are respectively set on both sides of the spine 4. The corresponding areas of the first medicated area 31, the second medicated area 32, and the third medicated area 33 form mounting hole structures on the brace body model.

[0093] CT or MRI scans were performed on the patient's spine (4), covering the area from the 7th thoracic vertebra to the 2nd lumbar vertebra, acquiring continuous tomographic images with a slice thickness ≤1mm. The tomographic images were converted into a 3D model containing the surface morphology, spinous process positions, and intervertebral disc angles of the spine (4) using a 3D reconstruction algorithm. Medical image processing techniques were then used to accurately extract the 3D coordinates of the spinous processes of the 7th thoracic vertebra, 11th thoracic vertebra, and 2nd lumbar vertebra, forming a personalized anatomical model of the spine (4), providing a data foundation for the precise localization of subsequent medication application.

[0094] On the three-dimensional model, the center points of the first medicated application area 31 are marked 4-6 cm horizontally on both sides of the spinous process of the 7th thoracic vertebra, with the center point of the spinous process of the 11th thoracic vertebra. Similarly, the center points of the second medicated application area 32 are marked 4-6 cm horizontally on both sides of the spinous process of the 11th thoracic vertebra. Finally, the center points of the third medicated application area 33 are marked 4.5-5.5 cm horizontally on both sides of the spinous process of the 2nd lumbar vertebra. The determination of the center points of each application area is based on the integration of traditional Chinese medicine meridian theory and modern anatomy: the first medicated application area 31 corresponds to the Diaphragm Shu point, the second medicated application area 32 corresponds to the Spleen Shu point, and the third medicated application area 33 corresponds to the Kidney Shu point.

[0095] The step of inserting the medicated dressing device 2 into the mounting hole 11 includes:

[0096] Prepare the shell 21 and the pull-out shell 22, and prepare the medicine package 24;

[0097] Place the medicine pack 24 inside the pull-out shell 22 and fix the medicine pack 24 with the movable frame 223;

[0098] Insert the pull-out shell 22 into the housing 21, flip the cover 212 and fix it to the side plate 214 of the housing 21;

[0099] Insert the housing 21 into the mounting hole 11 and tighten it.

[0100] In the step of inserting the medicated dressing device 2 into the mounting hole 11, the shell 21 and the pull-out shell 22 are first prepared. Both are made of medical-grade polymer materials (such as ABS or nylon) through injection molding to ensure structural strength and biocompatibility. Simultaneously, a medicine packet 24 containing powders of traditional Chinese medicines such as angelica, achyranthes, and cinnamon is prepared. The powders are mixed in equal proportions and then packaged in a breathable non-woven fabric bag. This modular preparation method facilitates large-scale production and personalized replacement.

[0101] The medicine pack 24 is laid flat on the first base plate 222 of the pull-out shell 22. By flipping the movable frame 223 to a vertical position, the top guard plate 2232 and the lower pressure plate 2233 form a three-dimensional clamping of the medicine pack 24. At the same time, the fixing protrusion 2235 on the side of the movable frame 223 is embedded in the fixing groove 2242 of the fixing plate 224 to form a fixation. The pull-out shell 22 with the medicine pack 24 fixed is inserted into the insertion groove 211 of the shell 21. The limiting strips 225 on both sides of the pull-out shell 22 slide and engage with the limiting grooves 2141 of the side plate 214 of the shell 21 to ensure accurate insertion direction. To ensure that the pull-out shell 22 does not easily fall out after insertion, the insertion port of the insertion slot 211 is set upward. After inserting the pull-out shell 22 into the insertion slot 211 from top to bottom, the flip cover 212 is flipped over to cover the insertion slot 211. The spring buckles 2121 on both sides of the flip cover 212 are elastically deformed and locked into the locking holes 2142 of the side plate 214 to form a seal. Finally, the shell 21 is aligned with the mounting hole 11 of the support body 1, so that the locking block 216 on the edge of the shell 21 is inserted into the mounting notch 111 on the outside of the mounting hole 11. By rotating the shell 21, the locking block 216 slides along the annular sliding groove 2243 on the inner side of the mounting hole 11 to the locking position. The anti-slip texture on the side wall of the sliding groove 2243 engages with the surface of the locking block 216 to provide circumferential friction and prevent loosening.

[0102] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
