Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary appliances in rehabilitation engineering, and in particular relates to a method for realizing digital automatic module design of a scoliosis orthosis. Background Art

[0002] Scoliosis is a complex and serious three-dimensional spinal deformity disease. Patients will not only suffer tremendous psychological pressure due to the obvious asymmetry of their body appearance, such as uneven shoulders, pelvic tilt, hunchback, etc., but also face many physical health problems. As the disease progresses, the curvature of the spine will continue to worsen, causing deformation of the chest, which in turn compresses important organs such as the heart and lungs, restricting the patient's respiratory function and significantly reducing exercise endurance. In severe cases, it may even be life-threatening. As an important means of non-surgical treatment, scoliosis orthoses are of particular significance for adolescent patients who are in a critical period of growth and development. It can provide effective external support, correct or control the development of scoliosis, significantly slow down or even prevent the further deterioration of the degree of spinal curvature, greatly reduce the patient's dependence on surgical treatment, bring hope to the patient's recovery, and is an important guarantee for improving the patient's quality of life.

[0003] The traditional scoliosis orthosis manufacturing process has many drawbacks that are difficult to overcome. In the manufacturing process, technicians mainly rely on soaking plaster bandages to cover the patient's torso to obtain the negative shape, then pour plaster slurry to make the positive shape, and then after tedious mold repair processing, use resin and other materials to finally make the orthosis. In this series of processes, the use of a large amount of plaster makes the working environment dirty and messy, and the large amount of dust pollution generated seriously threatens the health of technicians. Moreover, its manufacturing process parameters are extremely vague, mainly relying on the personal experience of technicians to judge, lack of precise quantitative standards, and cannot be checked and verified by digital means. This directly leads to poor adaptability of the orthosis produced, which is difficult to meet the personalized needs of patients. In addition, the traditional process saves almost no patient data, and the treatment process cannot be effectively traced and evaluated in the later stage, which is not conducive to optimizing the treatment plan according to the actual situation of the patient. Furthermore, the work efficiency of the traditional manufacturing process is extremely low, each step is time-consuming and labor-intensive, and it is difficult to achieve concurrent operations, which greatly prolongs the time for patients to obtain orthoses and seriously affects the treatment effect.

[0004] With the rapid development of digital technology, its application in the field of medical rehabilitation is becoming increasingly extensive and in-depth. In the field of orthotics, digital technology has brought new opportunities to break through the bottleneck of traditional processes. Three-dimensional scanning technology can quickly and accurately obtain a three-dimensional model of the patient's body, providing an indispensable and accurate data basis for the personalized design of orthotics. The application of computer-aided design (CAD) and computer-aided manufacturing (CAM) technology makes the design and production of orthotics more efficient and accurate. Through digital simulation and analysis, the design of orthotics can be optimized in a virtual environment, the correction effect can be predicted in advance, and repeated modifications in actual production can be effectively reduced. However, the current digital automatic module design implementation method for scoliosis orthotics still needs to be further improved and innovated, especially in the accuracy of automatic loading and personalized adjustment of modules, the fidelity of simulating traditional process operations, and the close integration with clinical practice. There are still many challenges and huge room for development. Summary of the invention

[0005] In view of the shortcomings in the current technical field, the purpose of the present invention is to propose a method for realizing the digital automatic modular design of a scoliosis orthosis. The present invention aims to provide a method for realizing the digital automatic modular design of a scoliosis orthosis, so as to overcome the many defects of the traditional orthosis manufacturing process, realize the comprehensive optimization of the design and production of the scoliosis orthosis, improve the correction effect of the orthosis, and enhance the quality of life of patients.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A method for realizing digital automatic module design of a scoliosis orthosis comprises the following steps:

[0008] Step S1: Patient data collection and integration: Use a 3D scanner to obtain a 3D model of the patient's spine, and perform an appearance examination, including evaluating posture symmetry, chest protrusion, and performing a flexion test; perform an imaging examination, including taking full spine anteroposterior and lateral X-rays, flexion X-rays, and bone age assessment; integrate all examination data to provide a basis for subsequent design;

[0009] Step S2: Three-dimensional model adjustment: The three-dimensional model obtained in step S1 is adjusted in terms of biomechanical position lines. The adjustment methods include translation, rotation, bending, elongation, shortening, expansion and other operations. The adjustment process is based on relevant technologies to ensure that it meets the patient's physiological structure and orthopedic needs;

[0010] Step S3: Automatic module loading: Based on various characteristic parameters of the patient's scoliosis, including deformity type, curvature, rotation angle, and trunk morphology, combined with the principle of the orthosis three-point pressure system, image X-rays, and mobility flexibility assessment results, the pre-set modules are loaded on the adjusted three-dimensional model. The module loading is achieved through specific operations. The default loading position and shape contour of each module are different, and the bottom layer is composed of adjustable grid points. After loading, the model can be automatically adapted;

[0011] Step S4: Module operation and control: The module has pressurization and release functions, and can be moved and strength operation can be selected according to the image data to achieve the change of the model shape to simulate the plaster positive treatment. The module contour can be adjusted before the operation and can be reset after the operation; the module for the symmetry requirement on both sides of the body can be mirrored to ensure the symmetry and stability of the orthosis; the design area can be compared before and after, including the pressure diagram and the overall contour comparison; the deformed module can be reset and further fine-tuned, including at least one or more of the position, contour and pressurization release intensity; the model can be cut and smoothed by simulating the real plaster craft tools;

[0091] Left rear lumbar release: In addition to the above waist-related effects, the left rear lumbar release module also helps relieve the pressure that may occur during lumbar correction.

[0092] Further, the operation of the pressurization module is implemented in the following way: each module can automatically pressurize and release the target area of ​​the model, that is, the surface shape of the 3D model changes; "regional pressurization" simulates "removing plaster" on the plaster positive model, and "regional release" simulates "filling plaster" on the plaster positive model;

[0093] For example, select the "left lumbar compression" module to apply pressure to the lumbar area of ​​a patient with left lumbar convexity;

[0094] The module position can be referenced by images such as X-rays, and moved by pulling the arrows;

[0095] Click the "Pressure" button to make a depression on the surface of the model to achieve a pressure effect. You can also select the "Pressure Strength" or the depth of the depression to change the shape.

[0096] Before pressing, the module outline can be resized horizontally or vertically; points can also be dragged to redraw the outline;

[0097] After pressurization, it can be reset to return to its original shape.

[0098] Further, the release module operation is implemented in the following way: each module can automatically release the target area of ​​the model, that is, the surface shape of the three-dimensional model is changed; "area release" is to simulate "filling plaster" on the plaster positive model;

[0099] For example, select the "Left Posterior Chest Release" module to release the chest area of ​​patients with right thoracic convexity to avoid compression of internal organs and affect breathing;

[0100] The module position can be referenced by images such as X-rays, and moved by pulling the arrows;

[0101] Click the "Release" button to make the surface of the model convex, achieving an expansion release effect, and you can select the "Release Strength", i.e. the height of the convexity, to change the shape;

[0102] Before releasing, the module outline can be resized horizontally or vertically; you can also drag the points to redraw the outline;

[0103] After pressurization, it can be reset to return to its original shape.

[0104] Furthermore, in the method for implementing the digital automatic module design of the scoliosis orthosis, the modules that need to be symmetrical on both sides of the body have a mirror operation function;

[0105] The "base" that ensures that the patient does not slip off after wearing it involves a design that compresses / releasing the areas on both sides of the iliac crest. It needs to be symmetrical and not compress the bones.

[0106] Mirror pressurization operation process: first select the "Left Iliac Wing Pressurization" module and click the "Pressure" button to create a depression on the model surface to achieve the pressurization effect. At this time, you can select the "Pressure Intensity" to determine the depth of the depression to change the shape. Then click the "Mirror" function, and select "Yes" when prompted "Do you want to mirror the shape on the opposite side?". The "Right Iliac Wing Pressurization" module is marked as "Right Iliac Wing Pressurization Mirror". Then select "Right Iliac Wing Pressurization Mirror" and click the "Pressure" button to accurately copy the depression treatment on the left side of the model surface, including the same pressurization effect and "pressurization intensity", to achieve consistent shape changes and ensure the symmetry and effectiveness of pressurization on both sides;

[0107] Mirror release operation process: first select the "Left Iliac Wing Release" module, click the "Release" button, let the model surface appear convex to achieve the release effect, and select the "Release Strength" to determine the convex height to change the shape. Click the "Mirror" button and click "OK" when prompted "Do you want to mirror the shape on the opposite side", and the "Right Iliac Wing Release" module will be transformed into "Right Iliac Wing Release Mirror". Finally, click the "Release" button to accurately copy the convex treatment of the model surface on the left side, with the same release effect and "Release Strength", ensuring the symmetry and equivalence of the release operations on both sides.

[0108] Furthermore, the obtained three-dimensional model is adjusted for biomechanical position lines in the following manner:

[0109] Three-dimensional model acquisition step: acquiring a three-dimensional model of the patient's trunk, which presents the surface morphology, bone structure and scoliosis characteristics of the patient's trunk, including at least one or more information of deformity type, curvature degree, rotation angle and trunk morphology, so as to meet subsequent adjustment needs;

[0110] Model section division steps: In the digital 3D technology software, the obtained 3D model is divided into multiple sections according to the key nodes and regional characteristics of the patient's scoliosis. The number of sections can be adjusted as needed according to the individual conditions of the patient. Adjustment points with unique identification and specific functions are set at both ends of each section. The adjustment points can be used to locate the parts that need to be adjusted and fixed, and effectively control the transition form between the two, playing a key guiding and controlling role in the model adjustment process;

[0111] Dynamic model transformation operation steps: select the model part covered by the adjustment points at both ends of the section as the target adjustment area, and the unselected part remains fixed. When operating the selected section, the 3D model part contained therein can be subjected to a variety of dynamic transformations based on the patient's real-time data and preset algorithms, including one or more of translation operation, rotation operation, personalized bending operation, adaptive elongation and shortening operation, and expansion operation;

[0112] Calibration line setting steps: according to the patient's real-time imaging data, calibration lines are marked on the deformed part. The number, position and shape of calibration lines can be automatically increased, optimized or adjusted according to the complexity of the patient's scoliosis and the correction needs. Calibration lines can be displayed / hidden in real time, and can also be highlighted according to importance and attention. When setting calibration lines, the imaging data is aligned with the 3D model through advanced image recognition and registration technology. The scaling and transparency parameters of the imaging data can be adjusted in real time according to the observation and analysis needs to ensure that the position and direction of the calibration lines accurately reflect the actual situation and dynamic changes of the deformed part;

[0113] Real-time rotation adjustment steps: Select the deformed part and light up the calibration line. Using the calibration line as a real-time reference, rotate the specific part including the chest and pelvis to parallel horizontal planes according to the patient's posture data and correction goals.

[0114] Horizontal calibration steps: Select the adjustment point on one side of the cross section, pull the blue arrow on the software interface, and use intelligent algorithms and real-time feedback to perform horizontal calibration operations, including precise parallel adjustment of the patient's high and low shoulder posture problems. The horizontal calibration accuracy can be automatically set according to the patient's body sensitivity and correction requirements, so that the patient's body posture is always correctly adjusted during dynamic changes;

[0115] Sagittal plane dynamic optimization adjustment steps: perform sagittal plane rotation and translation operations on the model to ensure that the adjustment of the orthosis in the sagittal plane can achieve the expected effect; including ensuring that the human spine always conforms to the normal physiological curve changes. The sagittal plane rotation and translation operations can automatically select the corresponding operating tools and control parameters according to the patient's individual conditions and treatment needs. During the operation, reference is made to the calibration line, muscle strength changes, bone morphology dynamics or model characteristics to achieve dynamic adaptability and accuracy of sagittal plane adjustment.

[0116] Furthermore, the specific operation modes of various dynamic transformations are as follows:

[0117] Translation operation: In different views of the software interface, including the front view, top view or sagittal view, select the adjustment point of the part to be adjusted, and automatically or manually drag the arrow along the corresponding coordinate axis according to the patient's body data and correction goals to achieve accurate translation of the model in that direction. The translation amount can be dynamically adjusted according to the patient's growth changes, treatment progress and real-time feedback information to ensure that each translation can achieve the best force-position adaptation effect;

[0118] Rotation operation: Divide the body model into multiple cross-sections, generate multiple calibration lines based on the patient's X-rays, pressure test diagrams or multi-source influence data of muscle strength distribution, observe the model from multiple perspectives including the front view or top view, select the adjustment point of the target rotation area, and rotate the adjustment point in the top view or other views according to the preset biomechanical model and correction strategy, so that the target area including the waist and pelvic area can be parallelly aligned or meet the relative position relationship of individual correction needs. The rotation angle and direction can be dynamically optimized according to the patient's real-time status;

[0119] Personalized bending operation: Import a standard 3D bone model that matches the patient's age, gender, and bone development stage, and align it precisely with the patient's model scanned markers. Use the normal human spine physiological curve and the patient's personalized correction plan as dual references to select the target area adjustment point. The model is adjusted to the bending point in that area through adjustment. The degree of bending can be adjusted in real time according to the dynamic changes of the patient's scoliosis to ensure that it always meets the best correction path.

[0120] Adaptive elongation and shortening operation: Based on the real-time monitoring data of the patient's muscle growth, bone development and body posture changes, select the adjustment point of the part to be adjusted, pull the blue arrow on the software interface up or down to achieve adaptive elongation or shortening of the model in the corresponding direction. The elongation or shortening amount can be automatically calculated and adjusted according to the dynamic changes of the body to maintain the continuous adaptability of the orthosis to the patient's body;

[0121] Expansion operation: According to the elasticity changes of the patient's body tissues, skin pressure distribution and correction needs, select the adjustment point in the target area, drag the red or green square on the software interface, and flexibly expand the model in the relevant direction. The expansion amplitude can be dynamically set according to the individual differences of the patients and the treatment stage. At the same time, multiple cross-section adjustment points can be selected at the same time as needed to make unified and coordinated adjustments in a larger area, or select the adjustment points on one side of the cross section for local fine adjustment;

[0122] The present invention adopts the above technical solution, which has at least the following beneficial effects:

[0123] 1. Personalized correction: The present invention is based on the collection and integration of comprehensive patient data, including multi-source data such as three-dimensional models, appearance and posture examinations, and imaging examinations. It can accurately analyze the specific characteristics of the patient's scoliosis, such as deformity type, degree of curvature, rotation angle, and trunk morphology. Through the classification and establishment of corresponding modules, a highly personalized orthotic design scheme is provided for patients with different types of scoliosis. For example, for patients with specific classifications such as pelvic rotation to the concave side of the chest and trunk imbalance to the convex side of the chest, a series of modules such as left iliac wing compression and right abdominal anti-rotation are established. These modules work together to accurately apply force and correction from different parts of the pelvis, spine, and body areas. It can effectively treat individual differences in patients, significantly improve the correction effect, and improve the scoliosis condition to the greatest extent, helping patients restore normal spinal morphology and body balance.

[0124] 2. Improve design efficiency and quality: The digital automatic module design implementation method greatly simplifies the cumbersome process of traditional orthosis manufacturing technology. In the module automatic loading step, based on patient data and orthosis principles, the pre-set modules can be quickly and accurately loaded on the three-dimensional model, and the default loading position and shape contour of each module are different and can automatically adapt to the model, reducing the time of manual repeated adjustment and trial and error. At the same time, in the module operation and control link, the pressurization, release, mirroring and other functions are easy to operate and can be accurately positioned and adjusted according to the image data. For example, by moving the module position with reference to the X-ray film and selecting the appropriate intensity for pressurization or release operations, the shape of the model can be quickly changed to simulate the plaster positive treatment, and the module contour can be flexibly adjusted before the operation, and it can be easily reset after the operation. In addition, the simulation of the real plaster process tools to perform regional cutting and smoothing of the model further improves the accuracy and efficiency of model processing. These digital operations not only shorten the design cycle of orthoses, allowing patients to obtain suitable orthoses more promptly, but also improve the accuracy and quality of the design, reduce errors caused by human factors, and thus improve the overall performance and correction effect of the orthosis.

[0125] 3. Improve patient comfort and compliance: Since precise and personalized correction can be achieved, the orthosis can better fit the patient's body curve, avoiding local excessive compression or discomfort caused by poor adaptability of traditional orthotics. For example, through modules such as chest release and left pectoralis major release, the pressure of the orthosis on the chest and related muscles can be effectively relieved, ensuring the normal physiological functions of the chest, such as smooth breathing, while reducing muscle fatigue and pain. In addition, the symmetry of the two sides of the body is taken into account during the design process, and the balance and stability of the orthosis are ensured through the mirror operation function, further improving the patient's comfort. This good wearing experience can significantly enhance the patient's compliance with long-term wearing of the orthosis, allowing patients to cooperate with treatment more actively, thereby improving the treatment effect and promoting the patient's recovery process.

[0126] 4. Facilitate clinical application and data management: The present invention facilitates collaboration among multidisciplinary teams such as clinicians, prosthetists and orthotists, and rehabilitation therapists. Doctors can develop scientific and reasonable treatment plans based on detailed patient data, orthotists can use digital automatic module design methods to efficiently design orthoses, and rehabilitation therapists can provide targeted feedback and suggestions based on the patient's rehabilitation progress. At the same time, the integration and storage of patient data also facilitates subsequent treatment tracking and effect evaluation. Through the accumulation and analysis of a large amount of patient data, it is also possible to further optimize the module design and orthosis manufacturing process, continuously improve product performance and quality, and provide strong support for the clinical application and development of scoliosis orthoses.

When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0173] like Figure 1 As shown, this embodiment provides a method for implementing a digital automatic module design of a scoliosis orthosis, comprising the following steps:

[0174] Step S1: Patient data collection and integration: Use a 3D scanner to obtain a 3D model of the patient's spine, and perform an appearance examination, including evaluating posture symmetry, chest protrusion, and performing a flexion test; perform an imaging examination, including taking full spine anteroposterior and lateral X-rays, flexion X-rays, and bone age assessment; integrate all examination data to provide a basis for subsequent design;

[0175] Step S2: Three-dimensional model adjustment: The three-dimensional model obtained in step S1 is adjusted in terms of biomechanical position lines. The adjustment methods include translation, rotation, bending, elongation, shortening, expansion and other operations. The adjustment process is based on relevant technologies to ensure that it meets the patient's physiological structure and orthopedic needs;

[0176] Step S3: Automatic module loading: Based on various characteristic parameters of the patient's scoliosis, including deformity type, curvature, rotation angle, and trunk morphology, combined with the principle of the orthosis three-point pressure system, image X-rays, and mobility flexibility assessment results, the pre-set modules are loaded on the adjusted three-dimensional model. The module loading is achieved through specific operations. The default loading position and shape contour of each module are different, and the bottom layer is composed of adjustable grid points. After loading, the model can be automatically adapted;

[0177] Step S4: Module operation and control: The module has pressurization and release functions, and can be moved and strength operation can be selected according to the image data to achieve the change of the model shape to simulate the plaster positive treatment.

[0249] Based on the characteristics of type 6, the modules are designed to correct scoliosis and restore the balance and normal shape of the trunk. The modules include one or more of the following:

[0250] Left / right iliac wing pressurization: By applying pressure to the left and right iliac wings, the scoliosis orthosis can be stabilized and fixed when worn, making it more fit and comfortable, and promoting the correction effect.

[0257] Left rear lumbar release: In addition to the above waist-related effects, the left rear lumbar release module also helps relieve the pressure that may occur during lumbar correction.

[0258] As a preferred implementation, the operation of the pressurizing module in this embodiment is implemented as follows: each module can automatically pressurize and release the target area of ​​the model, that is, the surface shape of the three-dimensional model changes; "regional pressurization" simulates "removing plaster" on the plaster positive mold, and "regional release" simulates "filling plaster" on the plaster positive mold;

[0259] Select the "Left Lumbar Compression" module to apply pressure to the lumbar area of ​​patients with left lumbar convexity;

[0260] The module position can be referenced by images such as X-rays, and moved by pulling the arrows;

[0261] Click the "Pressure" button to make a depression on the surface of the model to achieve a pressure effect. You can also select the "Pressure Strength" or the depth of the depression to change the shape.

[0262] Before pressing, the module outline can be resized horizontally or vertically; points can also be dragged to redraw the outline;

[0263] After pressurization, it can be reset to return to its original shape.

[0264] As a preferred implementation, the release module operation in this embodiment is implemented as follows: each module can automatically release the target area of ​​the model, that is, the surface shape of the three-dimensional model changes; "area release" is to simulate "filling plaster" on the plaster positive mold;

[0265] Select the "Left Posterior Chest Release" module to release the chest area of ​​patients with right thoracic convexity to avoid compression of internal organs and affect breathing;

[0266] The module position can be referenced by images such as X-rays, and moved by pulling the arrows;

[0267] Click the "Release" button to make the surface of the model convex, achieving an expansion release effect, and you can select the "Release Strength", i.e. the height of the convexity, to change the shape;

[0268] Before releasing, the module outline can be resized horizontally or vertically; you can also drag the points to redraw the outline;

[0269] After pressurization, it can be reset to return to its original shape.

[0270] Furthermore, in the method for implementing the digital automatic module design of the scoliosis orthosis, the modules that need to be symmetrical on both sides of the body have a mirror operation function;

[0271] The "base" that ensures that the patient does not slip off after wearing it involves a design that compresses / releasing the areas on both sides of the iliac crest. It needs to be symmetrical and not compress the bones.

[0272] Mirror pressurization operation process: first select the "Left Iliac Wing Pressurization" module and click the "Pressure" button to create a depression on the model surface to achieve the pressurization effect. At this time, you can select the "Pressure Intensity" to determine the depth of the depression to change the shape. Then click the "Mirror" function, and select "Yes" when prompted "Do you want to mirror the shape on the opposite side?". The "Right Iliac Wing Pressurization" module is marked as "Right Iliac Wing Pressurization Mirror". Then select "Right Iliac Wing Pressurization Mirror" and click the "Pressure" button to accurately copy the depression treatment on the left side of the model surface, including the same pressurization effect and "pressurization intensity", to achieve consistent shape changes and ensure the symmetry and effectiveness of pressurization on both sides;

[0273] Mirror release operation process: first select the "Left Iliac Wing Release" module, click the "Release" button, let the model surface appear convex to achieve the release effect, and select the "Release Strength" to determine the convex height to change the shape. Click the "Mirror" button and click "OK" when prompted "Do you want to mirror the shape on the opposite side", and the "Right Iliac Wing Release" module will be transformed into "Right Iliac Wing Release Mirror". Finally, click the "Release" button to accurately copy the convex treatment of the model surface on the left side, with the same release effect and "Release Strength", ensuring the symmetry and equivalence of the release operations on both sides.

[0274] As a preferred implementation, the three-dimensional model obtained in this embodiment is adjusted in the following way:

[0275] Three-dimensional model acquisition step: acquiring a three-dimensional model of the patient's trunk, which presents the surface morphology, bone structure and scoliosis characteristics of the patient's trunk, including at least one or more information of deformity type, curvature degree, rotation angle and trunk morphology, so as to meet subsequent adjustment needs;

[0276] Model section division steps: In the digital 3D technology software, the obtained 3D model is divided into multiple sections according to the key nodes and regional characteristics of the patient's scoliosis. The number of sections can be adjusted according to the individual conditions of the patient. Adjustment points with unique identification and specific functions are set at both ends of each section. The adjustment points can be used to locate the parts that need to be adjusted and fixed, and effectively control the transition form between the two, playing a key guiding and controlling role in the model adjustment process;

[0277] Dynamic model transformation operation steps: select the model part covered by the adjustment points at both ends of the section as the target adjustment area, and the unselected part remains fixed. When operating the selected section, the 3D model part contained therein can be subjected to a variety of dynamic transformations based on the patient's real-time data and preset algorithms, including one or more of translation operation, rotation operation, personalized bending operation, adaptive elongation and shortening operation, and expansion operation;

[0278] Calibration line setting steps: according to the patient's real-time imaging data, calibration lines are marked on the deformed part. The number, position and shape of calibration lines can be automatically increased, optimized or adjusted according to the complexity of the patient's scoliosis and the correction needs. Calibration lines can be displayed / hidden in real time, and can also be highlighted according to importance and attention. When setting calibration lines, the imaging data is aligned with the 3D model through advanced image recognition and registration technology. The scaling and transparency parameters of the imaging data can be adjusted in real time according to the observation and analysis needs to ensure that the position and direction of the calibration lines accurately reflect the actual situation and dynamic changes of the deformed part;

[0279] Real-time rotation adjustment steps: select the deformed part and light up the calibration line. Using the calibration line as a real-time reference, according to the patient's posture data and correction goals, rotate the specific parts including the chest and pelvic horizontal planes to parallel or corrected positions; the rotation adjustment can be automatically set according to the patient's body sensitivity, flexibility and other examination evaluation indicators, as well as the correction requirements, so that the patient's body posture is always correctly adjusted in dynamic changes;

[0280] Horizontal calibration steps: Select the adjustment point on one side of the cross section, pull the blue arrow on the software interface, and use intelligent algorithms and real-time feedback to perform horizontal calibration operations, including precise parallel adjustment of the patient's high and low shoulder posture problems. The horizontal calibration accuracy can be automatically set according to the patient's body sensitivity, flexibility and other examination evaluation indicators, as well as correction requirements, so that the patient's body posture is always correctly adjusted in dynamic changes;

[0281] Sagittal plane dynamic optimization adjustment steps: perform sagittal plane rotation and translation operations on the model to ensure that the adjustment of the orthosis in the sagittal plane can achieve the expected effect; including ensuring that the human spine always conforms to the normal physiological curve changes. The sagittal plane rotation and translation operations can automatically select the corresponding operating tools and control parameters according to the patient's individual conditions and treatment needs. During the operation, reference is made to the calibration line, muscle strength changes, bone morphology dynamics or model characteristics to achieve dynamic adaptability and accuracy of sagittal plane adjustment.

[0282] As a preferred implementation, the specific operation modes of multiple dynamic transformations in this embodiment are as follows:

[0283] Translation operation: In different views of the software interface, including the front view, top view or sagittal view, select the adjustment point of the part to be adjusted, and automatically or manually drag the arrow along the corresponding coordinate axis according to the patient's body data and correction goals to achieve accurate translation of the model in that direction. The translation amount can be dynamically adjusted according to the patient's growth changes, treatment progress and real-time feedback information to ensure that each translation can achieve the best force-position adaptation effect;

[0284] Rotation operation: Divide the body model into multiple cross-sections, generate multiple calibration lines based on the patient's X-rays, pressure test diagrams or multi-source influence data of muscle strength distribution, observe the model from multiple perspectives including the front view or top view, select the adjustment point of the target rotation area, and rotate the adjustment point in the top view or other views according to the preset biomechanical model and correction strategy, so that the target area including the waist and pelvic area can be parallelly aligned or meet the relative position relationship of individual correction needs. The rotation angle and direction can be dynamically optimized according to the patient's real-time status;

[0285] Personalized bending operation: Import a standard 3D bone model that matches the patient's age, gender, and bone development stage, and align it precisely with the patient's model scanned markers. Use the normal human spine physiological curve and the patient's personalized correction plan as dual references to select the target area adjustment point. The model is adjusted to the bending point in that area through adjustment. The degree of bending can be adjusted in real time according to the dynamic changes of the patient's scoliosis to ensure that it always meets the best correction path.

[0286] Adaptive elongation and shortening operation: Based on the real-time monitoring data of the patient's muscle growth, bone development and body posture changes, select the adjustment point of the part to be adjusted, pull the blue arrow on the software interface up or down to achieve adaptive elongation or shortening of the model in the corresponding direction. The elongation or shortening amount can be automatically calculated and adjusted according to the dynamic changes of the body to maintain the continuous adaptability of the orthosis to the patient's body;

[0287] Expansion operation: According to the elasticity changes of the patient's body tissues, skin pressure distribution and correction needs, select the adjustment point in the target area, drag the red or green square on the software interface, and flexibly expand the model in the relevant direction. The expansion amplitude can be dynamically set according to the individual differences of the patients and the treatment stage. At the same time, multiple cross-section adjustment points can be selected at the same time as needed to make unified and coordinated adjustments in a larger area, or select the adjustment points on one side of the cross section for local fine adjustment;

[0288] Embodiment 2

[0289] This embodiment provides a specific implementation method of the method for implementing the digital automatic module design of a scoliosis orthosis:

[0290] Step S1, obtaining a three-dimensional model of the patient's spine through a three-dimensional scanner; and performing an appearance and posture examination including:

[0291] Postural symmetry: Observe the patient while standing and sitting, with an emphasis on assessing the symmetry of the shoulders, scapulae, pelvis, and trunk.

[0292] Chest bulge: Check for chest bulge due to spinal rotation.

[0293] Flexion test: The patient bends forward and observes whether there is a bulge in the back (rib bulge / lumbar rotation)

[0294] Imaging tests include:

[0295] Full spine anteroposterior and lateral X-rays: used to measure the Cobb angle of scoliosis and determine the severity of the curve

[0296] Flexion X-ray: evaluate the flexibility of the spine and distinguish between structural and non-structural scoliosis. Bone age assessment: usually through the Risser sign to determine the patient's growth potential.

[0297] Step S2, adjusting the biomechanical force line of the three-dimensional model obtained in step S1;

[0298] Step S3: According to the deformity type (such as C-type or S-type scoliosis), degree of curvature, rotation angle and trunk morphology of the scoliosis patient, the effect of the orthosis usually depends on a three-point pressure system (two fixed points and one main correction point), etc., combined with X-ray images, range of motion and flexibility assessment, etc.

[0299] Automatically load the modules that need to be designed on the 3D model. The situations are divided into the following:

[0300] Classification 1 and module establishment: Figure 2 and Figure 3 As mentioned above, the classification characteristics are described as follows: This classification may correspond to a specific scoliosis morphology, such as the pelvis turning to the concave side of the chest, which means that the position of the pelvis has shifted relative to the normal state and rotated toward the side of the concave chest. The trunk is unbalanced on the convex side of the chest, indicating that the center of gravity of the body is significantly shifted to the side of the convex chest, resulting in the overall balance of the trunk being broken. The rib crests on the back of the chest extend to the waist area and there is no or very little waist protrusion, which means that the rib bulge on the back of the chest is more obvious and extends to the waist range, while the waist is relatively flat, without obvious abnormal protrusions or curvatures.

[0301] Basis and function of module establishment: Based on this classification feature, the modules are designed to correct scoliosis and restore the balance and normal shape of the trunk in a targeted manner. For example, a compression module may be set up in a specific area of ​​the chest to apply reverse pressure to the convex side of the chest in an attempt to correct the deformity of the chest; a stabilization and correction module may be set up in the pelvic area to improve the abnormal rotation of the pelvis by adjusting the position and force of the pelvis; an auxiliary support and balance module may be set up in the waist. Although the lumbar protrusion is not obvious, in order to maintain the continuity correction of the entire spine and trunk, moderate support force is provided to prevent new problems in the waist during the correction process or to assist in the conduction and dispersion of force, so that the corrective effect of the entire orthosis can be synergistically exerted, better guide the spine towards a normal shape, and gradually restore the physiological curve of the spine and the balance and symmetry of the trunk.

[0302] Module operation instructions:

[0303] Pressurization module (such as left iliac wing pressurization, left lumbar spine pressurization, right thoracic spine pressurization, etc.): When designing the orthosis, select the corresponding pressurization module according to the scoliosis of the corresponding part of the patient, click the "pressurization" button through the operation interface, and determine the appropriate position with the assistance of imaging data. After adjusting the module contour as needed, apply pressure to the corresponding part of the model to achieve concave processing to simulate the correction force, and then reset or further fine-tune according to the actual situation.

[0304] Release module (such as front release, left rear chest release, chest release, etc.): For areas where excessive pressure may occur, select the corresponding release module and click the "Release" button. Similarly, refer to the image to move the position and adjust the contour to create a convex effect on the model surface to achieve the purpose of releasing pressure. After the operation, it can be reset as needed to ensure the comfort and normal function of the area.

[0305] Anti-rotation module (such as upper anti-rotation, right abdominal anti-rotation, left pelvic anti-rotation, etc.): Based on the patient's spinal rotation deformity, the anti-rotation module is activated. According to relevant images and patient posture data, reverse force is applied to the corresponding spinal area on the model to correct the rotation problem and ensure normal alignment of the spine.

[0306] Cropping module (such as left-side adversarial cropping): During the orthosis production stage, this module is used to crop specific areas of the model according to the preset operation process to make it conform to the shape and wearing requirements of the final orthosis.

[0307] Possible application scenarios: Suitable for scoliosis patients whose pelvis turns to the concave side of the chest, whose trunk is unbalanced on the convex side of the chest, whose rib crests extend to the waist area, and whose waist protrusion is small or nonexistent. Such patients often have problems such as abnormal pelvic position affecting the overall shape of the spine, thoracic scoliosis, and uneven pressure in related areas. The above module operation can correct the deformities of different parts of the pelvis and spine in a targeted manner, relieve local pressure, and restore the balance and normal shape of the trunk.

[0308] Type II and module establishment: Figure 4 and Figure 5 As shown in the figure, according to the information in the figure, the 4C type of right-convex chest and left-convex waist has the following characteristics: The pelvis is turned to the convex chest side: this means that the position of the pelvis is biased towards the convex chest side. The trunk is unbalanced on the concave chest side: the balance of the trunk is broken, and the center of gravity is biased towards the concave chest side. The rib peaks can be seen in the waist and back, and the waist and back are obviously protruding: there are obvious rib bulges and protrusions in the waist and back.

[0309] These modules are designed to work in synergy with each other. For example, adjustments to the pelvis-related modules can provide a basis for correction of the spine and trunk, because the pelvis is the base of the spine. By applying pressure to the left pelvis and anti-rotating the right pelvis, the position of the pelvis can be stabilized and its adverse effects on the spine can be reduced. The upper anti-rotation and subthoracic anti-rotation modules work together to correct the rotation of the spine from the upper part of the spine and below the chest, respectively, and improve the overall balance of the trunk. The left lumbar compression and left rear chest release modules target the protrusion of the waist and back, one for pressure correction and the other for release and relief, thereby achieving the purpose of improving the shape of the waist and back.

[0310] Module operation instructions:

[0311] Pelvic related modules (left pelvic pressurization, right pelvic anti-rotation): In view of the characteristic that the pelvis turns to the thoracic convex side, select the left pelvic pressurization module, and adjust the pelvic position through appropriate operations to make it straight; at the same time, use the right pelvic anti-rotation module to correct the pelvic rotation problem, maintain the normal rotation state of the pelvis, and ensure that a stable foundation is provided for spinal correction.

[0312] Spine and trunk balance module (upper anti-rotation, subthoracic anti-rotation, left lumbar compression, left rear chest release): Taking into account the imbalance of the trunk on the concave side of the chest and the obvious protrusion of the waist and back, the upper anti-rotation and subthoracic anti-rotation modules are activated to correct the rotation problems of the upper spine and below the chest and improve the balance of the trunk; the left lumbar compression module is used to correct the left convexity of the lumbar spine and reduce the protrusion of the waist and back, and the left rear chest release module is used to relieve the pressure behind the chest to avoid excessive compression on the chest and back.

[0313] Application scenario: For patients with scoliosis whose pelvis rotates to the convex side of the chest, whose trunk is unbalanced to the concave side of the chest, whose rib peaks are visible in the waist and back, and whose waist and back are obviously protruding. Such patients have changes in waist and back shape and imbalance of the trunk due to pelvic rotation and scoliosis. These module operations help restore the normal position of the pelvis, correct spinal deformity, and relieve the pressure on the waist and back, so as to achieve the purpose of overall correction and restoration of balance.

[0314] Classification three and module establishment: Figure 6 and Figure 7 As shown, the characteristics of type three are:

[0315] The pelvis turns to the concave side of the waist: The pelvis is located below the spine in the human body structure and plays an important role in supporting and connecting the spine and lower limbs. When the pelvis turns to the concave side of the waist, it means that the position of the pelvis has shifted, which will affect the normal alignment of the spine. From a biomechanical point of view, this shift of the pelvis will change the pressure distribution on the spine, making the spine more susceptible to deformities such as scoliosis in the lumbar area.

[0316] For example, during daily activities, this change in pelvic position may cause patients to feel uneven force on the waist when standing or walking, which may aggravate the discomfort in the waist.

[0317] Trunk imbalance on the lumbar convex side: The balance of the trunk depends on the normal shape of the spine and the synergy of the muscles. When the trunk is imbalanced on the lumbar convex side, it indicates that the scoliosis of the waist has caused the asymmetry of the trunk. This imbalance not only affects the patient's appearance, but also has a chain reaction on other functions of the body.

[0318] For example, prolonged trunk imbalance may cause the lower back muscles to become overly tense in an attempt to maintain body balance, leading to lower back muscle strain and pain.

[0319] Significant lumbar protrusion, no thoracic and dorsal rib peaks: Significant lumbar protrusion refers to a more obvious protrusion of the lumbar spine. This protrusion may be caused by the combined effect of lumbar vertebral rotation and scoliosis. Since there is no thoracic and dorsal rib peak feature, it means that the main concentration of scoliosis is in the lumbar region, while the chest is relatively normal.

[0320] Clinically, patients with this type of scoliosis may experience symptoms such as limited lumbar movement and increased lumbar pain when bending over.

[0321] Module operation instructions:

[0322] Pelvic related modules (left pelvic pressurization, right pelvic anti-rotation, etc.): In view of the characteristic of the pelvis turning to the lumbar concave side, operate the left pelvic pressurization module to correct the pelvic deviation and restore it to its normal position, creating conditions for subsequent spinal correction; use the right pelvic anti-rotation module to prevent or correct pelvic rotation and reduce its adverse effects on the lumbar spine.

[0323] Lumbar-related modules (left lumbar compression, right rear lumbar release, etc.): For lumbar bulge, use the left lumbar compression module to apply pressure to the lumbar spine to correct the left bulge and restore the normal curvature of the lumbar spine; use the right rear lumbar release module to relieve pressure on the back of the waist, avoid excessive compression and help relax the waist muscles.

[0324] Trunk balance and spinal anti-rotation modules (upper anti-rotation, subthoracic anti-rotation): In order to correct the upper spinal rotation caused by trunk imbalance and the spinal rotation below the chest caused by lumbar convex imbalance, the upper anti-rotation and subthoracic anti-rotation modules are activated to adjust the upper spine posture, optimize the spinal alignment in the lumbar area, and improve the overall balance of the trunk.

[0325] Application scenario: It is suitable for patients with scoliosis whose pelvis is turned to the concave side of the waist, whose trunk is unbalanced to the convex side of the waist, whose waist is prominent and whose ribs are not ribbed. The main problems of these patients are the abnormal position and shape of the pelvis and waist spine and the imbalance of the trunk. The above module operation can correct the pelvis, waist and spine as a whole from many aspects, relieve waist protrusion and related pressure problems, and restore body balance.

[0326] Classification 4 and module establishment: Figure 8 and Fig. 9 As shown, the characteristics of type 4 are:

[0327] Pelvic rotation to the right: Pelvic rotation to the right means that the human pelvis has shifted to the right relative to the normal position in the sagittal or coronal plane. From a biomechanical point of view, this shift will cause the body's center of gravity to change, which in turn affects the force distribution of the spine. Normally, the pelvis is the base of the spine, and changes in its position will have a chain reaction on the shape of the spine, increasing the risk of scoliosis.

[0328] In clinical observation, patients with a pelvic rotation to the right may show the appearance of a relatively shortened right lower limb, may have a limp when walking, and may have asymmetric tension or relaxation of the waist and hip muscles.

[0329] Chest bulging to the left: A bulging chest indicates that the spine has a leftward curvature deformity in the chest area. This deformity may be caused by long-term poor posture, muscle imbalance or congenital factors. The scoliosis of the thoracic spine will affect the normal shape of the thorax, which in turn affects the function of internal organs such as the heart and lungs.

[0330] Clinically, such patients may experience symptoms of limited cardiopulmonary function such as dyspnea and palpitations. At the same time, due to changes in the thoracic morphology, the patient's body appearance will also be significantly affected, such as unequal shoulders and bulging back.

[0331] Module operation instructions:

[0332] Pelvic related modules (right iliac wing pressurization, left iliac wing release): In case the pelvis may turn to the right, operate the right iliac wing pressurization module to help correct the pelvic rotation and return it to its normal position, laying the foundation for spinal correction; at the same time, cooperate with the left iliac wing release module to adjust the force balance on both sides of the pelvis and assist in the correction of the pelvic position.

[0333] Chest-related modules (left thoracic vertebrae pressurization, right chest release): For the problem of chest bulging to the left, select the left thoracic vertebrae pressurization module to correct the left chest bulge and restore the normal curvature of the thoracic spine; and use the right chest release module to relieve the pressure on the right chest due to compensation, which is beneficial to the overall recovery of the chest shape.

[0334] Spine anti-rotation module (upper anti-rotation, subthoracic anti-rotation): Taking into account the rotation of the upper spine caused by the left convexity of the chest and the rotation of the spine below the chest, the upper anti-rotation and subthoracic anti-rotation modules are activated to correct the rotation of the corresponding areas and improve the overall alignment of the spine.

[0335] Application scenario: Suitable for patients with pelvic rotation to the concave side of the chest, torso imbalance to the convex side of the chest, rib crests extending to the waist area, and no or very small waist protrusion. These module operations can correct the rotation and curvature problems of the pelvis, thoracic spine, and overall spine of such patients, and restore torso balance and normal shape.

[0336] Classification 5 and module establishment: Fig.10 and Fig.11 Shown: Characteristics of Type 5:

[0337] Pelvic rotation to the left: Pelvic rotation to the left means that the pelvis has shifted to the left relative to its normal position in the coronal or sagittal plane of the human body. From a biomechanical point of view, this shift will disrupt the normal force balance of the body and change the support base of the spine. Usually, the pelvis serves as the base of the spine, and changes in its position will produce traction on the spine, leading to deformities such as scoliosis.

[0338] In clinical practice, patients with a pelvic rotation to the left may have a relatively shortened left lower limb and a gait that leans to the left when walking. The stress state of the muscles in the waist, buttocks and lower limbs will change, and some muscles may become overly tense due to compensation.

[0339] The waist is bulging to the right: The waist is bulging to the right, which means that the spine is bent to the right in the waist area. This type of lumbar scoliosis may be caused by abnormal pelvic position, long-term bad posture (such as long-term unilateral bending at work), muscle strength imbalance, etc. Lumbar scoliosis will cause changes in the appearance of the waist, such as bulging on one side of the waist, and it will also affect the function of the waist muscles and nerves.

[0340] Clinically, such patients may experience low back pain, stiffness, and limited mobility. In severe cases, it may affect nerve conduction in the lower limbs, leading to symptoms such as numbness and weakness in the lower limbs.

[0341] The chest bulges to the right: The chest bulges to the right, which reflects the curvature of the spine in the chest area. This thoracic scoliosis may be related to the lumbar scoliosis, and is the manifestation of the entire scoliosis deformity in the chest. Thoracic scoliosis affects the shape of the chest, which in turn affects cardiopulmonary function.

[0342] Patients may experience symptoms of limited cardiopulmonary function, such as difficulty breathing, chest tightness, and palpitations. Due to changes in the thoracic morphology, the appearance may manifest as unequal shoulders and a bulging back.

[0343] Module operation instructions:

[0344] Pressurization module (such as left iliac wing pressurization, left thoracic vertebra pressurization, right lumbar vertebra pressurization, right pelvic pressurization, etc.): Select the corresponding pressurization module according to the scoliosis of different parts of the patient's pelvis and spine. Refer to the imaging data to determine the exact position during operation. After adjusting the module contour, click the "Pressure" button to apply appropriate pressure to the corresponding part and change the shape of the model to achieve the correction purpose. You can reset or fine-tune the strength, contour and other parameters as needed later.

[0345] Release module (such as chest release, left pectoralis major release, right posterior chest release, etc.): In order to solve the pressure problems that the orthosis may cause to the chest, muscles and other parts, select the corresponding release module, click the "Release" button and combine the image movement, contour adjustment and other operations to make the model surface produce a convex effect, release pressure, and ensure the normal function and comfort of related parts.

[0346] Anti-rotation modules (such as upper anti-rotation, left pelvic anti-rotation, subthoracic anti-rotation, left abdominal anti-rotation, etc.): According to the rotation deformity of different areas of the patient's spine, the corresponding anti-rotation module is activated. With the help of image and body shape data, reverse force is applied to the corresponding part of the spine on the model to correct the rotation problem and maintain normal spinal alignment.

[0347] Cutting module (such as right-side antagonistic cutting a, right-side antagonistic cutting b): In the orthosis production process, the cutting module is used to cut specific areas of the model according to the established operating procedures to make it meet the production requirements and ensure the fit and practicality of the final orthosis.

[0348] Possible application scenarios: Suitable for patients with scoliosis whose pelvis is tilted to the convex side of the chest, the trunk is unbalanced to the concave side of the chest, the rib peaks are visible in the waist and back, and the waist and back are obviously protruding. It can comprehensively correct various problems such as abnormal pelvic position, scoliosis and rotation in different parts of the spine, and uneven pressure in related parts of the body. Through the coordinated operation of various modules, it can restore the balance of the trunk, correct spinal deformities and improve the comfort of patients wearing orthotics.

[0349] Classification 6 and module establishment: Fig.12 and Fig.13 Shown: Characteristics of Type 6:

[0350] Pelvic rotation to the left: Pelvic rotation to the left will cause the body's center of gravity to shift to the left, disrupting the normal body balance. From a biomechanical point of view, this will produce a lateral pull on the spine, resulting in uneven force on the spine, which in turn causes scoliosis. In clinical observations, patients may experience increased weight bearing on the left lower limbs and tension in the left hip muscles, which may lead to wear and pain in the left lower limb joints in the long term.

[0351] The waist bulges to the right: The waist bulges to the right is a manifestation of scoliosis of the spine in the lumbar area. This scoliosis may be caused by the pelvis turning to the left, and the lumbar spine bulges to the right in order to maintain balance. Lumbar scoliosis will affect the normal physiological curvature of the waist, resulting in unbalanced force on the waist muscles. Some muscles will become fatigued and painful due to excessive stretching or contraction. The patient may feel stiff waist and limited movement.

[0352] No rib hump on the back: No rib hump on the back indicates that the chest is relatively normal, and there is no obvious chest deformity caused by scoliosis. This means that the scoliosis is mainly concentrated in the lumbar area, and the spine and chest shape of the chest remain basically normal, with relatively little impact on cardiopulmonary function.

[0353] Module operation instructions:

[0354] Pelvic related modules (left iliac wing pressurization, right iliac wing release, left pelvic anti-rotation, right anterior pelvic anti-rotation): Because the pelvis may turn to the left, operate the left iliac wing pressurization module to correct the pelvic rotation and restore the normal position; combine with the right iliac wing release module to balance the forces on both sides of the pelvis; at the same time, use the left pelvic anti-rotation and right anterior pelvic anti-rotation modules to maintain the normal rotation state of the pelvis and correct the rotation problem of the corresponding spinal part on the right anterior side of the pelvis, reduce the adverse effects on the lumbar spine, and ensure the normal arrangement of the spine in the lumbar area.

[0355] Lumbar-related modules (right lumbar compression, left rear lumbar release): In case the waist bulges to the right, the right lumbar compression module is used to correct the right lumbar bulge and restore the normal curvature of the lumbar spine; the left rear lumbar release module is used to relieve the pressure on the left side of the waist caused by uneven force on both sides of the body, avoiding excessive pressure on the left side of the waist.

[0356] Chest-related module (chest release): Considering that the chest may be affected during waist correction, the chest release module is enabled to relieve chest pressure and ensure normal physiological function of the chest.

[0357] Possible application scenarios: Suitable for scoliosis patients with pelvis turned to the concave side of the waist, trunk imbalance on the convex side of the waist, significant lumbar protrusion, and no rib peaks on the chest and back. Through the above module operation, the patient's scoliosis problems can be corrected from multiple aspects such as pelvis, waist, and chest, relieving pressure on related parts and restoring trunk balance and normal shape.

[0358] In general, the operations of each module under different classifications are closely centered around the corresponding scoliosis characteristics. Through coordinated cooperation, they aim to provide accurate and effective orthosis design and correction plans for patients with different types of scoliosis, thereby improving patients' quality of life and rehabilitation effects.

[0359] Step S4, such as Fig.14 As shown in the figure. Each module is loaded at a different location and has a different shape. The bottom layer is composed of many grid points, such as Fig.14 The thoracic vertebrae compression and anterior release modules in the model. Each module can automatically perform compression and release operations on the target area of ​​the model, that is, the surface shape of the 3D model changes. "Regional compression" simulates "removing plaster" on the plaster positive model, and "regional release" simulates "filling plaster" on the plaster positive model.

[0360] Example of pressurization module operation:

[0361] like Fig.15 As shown, select the "left lumbar compression" module to apply pressure to the lumbar area of ​​patients with left lumbar convexity.

[0362] like Fig.16 As shown, the module position can be referenced by images such as X-rays, and the module can be moved by pulling the arrow;

[0363] like Fig.17 As shown, click the "Pressure" button to make a depression on the surface of the model to achieve a pressurized effect, and you can select the "Pressure Strength", that is, the depth of the depression, to change the shape.

[0364] like Fig.18 As shown, before pressurization, the module outline can be adjusted horizontally or vertically; the outline can also be redrawn by dragging the points.

[0365] After pressurization, it can be reset to return to its original shape.

[0366] Example of releasing module operation:

[0367] like Fig.19 As shown, select the "Left Posterior Chest Release" module to release the chest area of ​​patients with right thoracic convexity to avoid compression of internal organs and affect breathing.

[0368] like Fig. 20 As shown, the module position can be referenced by images such as X-rays, and the module can be moved by pulling the arrow;

[0369] like Fig.21 As shown, click the "Release" button to make the surface of the model convex to achieve an expansion release effect, and you can select the "Release Strength", that is, the height of the convexity, to change the shape.

[0370] like Fig. 22 As described above, before releasing, the module outline can be adjusted horizontally or vertically; the outline can also be redrawn by dragging points.

[0371] After pressurization, it can be reset to return to its original shape.

[0372] Step S5: Modules that need to be symmetrical on both sides of the body can be mirrored.

[0373] For example, the "base" of a scoliosis orthosis is to ensure that the patient does not slip off after wearing it. It requires a design that applies pressure and releases pressure on both sides of the iliac crest, with symmetry and without compressing the bones.

[0374] Mirror image compression operation

[0375] like Fig.23 As shown, select the "Left Iliac Wing Pressurization" module and click the "Pressure" button to make a depression on the surface of the model to achieve a pressurization effect. You can also select the "Pressure Intensity", that is, the depth of the depression, to change the shape.

[0376] like Fig.24 As shown, click the "Mirror" function and it will prompt "Do you want to mirror the shape on the opposite side?"

[0377] like Fig.25 As shown, after selecting "Yes", the "Right Iliac Wing Compression" module is marked as "Right Iliac Wing Compression Mirror";

[0378] Select "Right iliac wing compression mirror" and click the "Compression" button to copy the concave image on the left side of the model surface.

[0379] Sinking treatment, same pressure effect, same "pressure intensity", that is, change of shape.

[0380] Image release operation

[0381] like Fig.26 As shown, select the "Left Iliac Wing Release" module and click the "Release" button to make a convex treatment on the surface of the model to achieve a release effect. You can also select the "Release Strength", that is, the height of the convexity, to change the shape.

[0382] like Fig. 27 As shown, click the "Mirror" button and you will be prompted "Do you want to mirror the shape on the opposite side?" Click "OK" to form a mirror image.

[0383] like Fig.28 As shown, the "right iliac wing release" module becomes the "right iliac wing release mirror"

[0384] Click the "Release" button to copy the bulge on the left side of the model surface;

[0385] Processing, same release effect, same "release intensity", i.e. change of shape.

[0386] like Fig.29 As shown, the shapes of both sides after the mirror pressure and release operations are completed:

[0387] Step S6, as Fig.30 As shown, for the designed area, the before and after comparison is implemented. Pressure diagram, overall outline, such as before loading each module design:

[0388] like Fig.31 As shown, after selecting each module to perform "pressurization" or "release" operations, the graphic comparison is as follows:

[0389] like Fig.32 As described above, after selecting each module to perform the "pressurization" or "release" operation, the outer contour is compared: step S7, such as Fig.33 As shown, the deformed modules can be reset, such as the "left lumbar vertebrae compression" module, which has been selected and "pressurized". After clicking "Reset", it returns to its original shape.

[0390] like Fig.34 As shown, after resetting, the left lumbar region has returned to its original shape:

[0391] Step S8, Fig.35 As shown, the "machete" function in the tool that simulates the actual plaster process is used to perform area cutting; the "left side anti-cutting" module is selected, and the cutting area is planned on the left side of the line;

[0392] like Fig.36 As shown, click the "Adjust" button and drag the points to modify the cropped area.

[0393] like Fig.37 As shown, click the "Crop" button to cut out the area. Fig.37 Results after resection:

[0394] Step S9, as Fig.38 As shown, the "file" tool that simulates the actual plaster craft is used to smooth the surface of the model; click the "file" button and select the operation "radius" to control the operation area; select the operation "strength" to control the intensity of the smoothing treatment of the model surface.

[0395] Step S10, cutting line module

[0396] like Fig.39 As shown, after designing, you need to plan the "cutting line" and select the "overall cutting line" module

[0397] like Fig.40 As shown, click the "Adjust" button to drag the "point" to modify the direction of the cutting line;

[0398] like Fig.41 As shown in the figure, after clicking "Generate Cut Line", "raised" lines appear on the model surface;

[0399] Step S11, analogous to the plaster process, digitally and quickly obtain a complete design model;

[0400] like Fig.42 and Fig.43 As shown, the shape of the orthosis after molding needs to retain the functional areas, namely the "pressurization" and "release" modules, and remove the excess parts to make the orthosis as light as possible while ensuring the orthotic effect.
