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 dynamic adaptation and adjustment of digital force position and force line of a scoliosis orthosis. Background Art

[0002] Scoliosis is a common and complex spinal deformity, and its incidence in adolescents cannot be underestimated. It is characterized by the deviation of the spine from the normal physiological curve in three-dimensional space, showing abnormal forms such as lateral curvature and vertebral rotation. This not only causes the patient's body to be unbalanced, but also causes obvious appearance changes such as uneven shoulders, pelvic tilt, and hunchback, which brings psychological pressure to the patient. More seriously, as the disease progresses, the spinal deformation continues to intensify, the chest space is squeezed and deformed, and the normal development and functional operation of important organs such as the heart and lungs are seriously hindered. Impaired cardiopulmonary function is directly manifested as shortness of breath and decreased exercise endurance. Long-term cardiopulmonary diseases can cause serious threats to the patient's life, health and quality of life. In this context, scoliosis orthoses have become an important non-surgical intervention method. By applying external support to the spine, they play a key role in the patient's growth and development stage, can effectively prevent scoliosis from further deteriorating, and provide many adolescent patients with the possibility of avoiding surgical treatment. Slowing down or stopping the process of spinal curvature is an important hope for improving the patient's condition and prognosis. The production and adjustment process of traditional scoliosis orthoses is mired in many problems. The manufacturing process is extremely complicated, starting with the use of soaked plaster bandages to wrap the patient's torso to obtain the negative shape, and then going through a series of lengthy and complicated manual operations such as plaster slurry pouring, positive molding, and mold repairing, before finally being able to make an orthosis that can be used by patients. In this process, the extensive use of plaster makes the working environment dirty and dusty, causing direct damage to the health of technicians, and also posing environmental risks. The manufacturing process is highly dependent on the personal experience of technicians, lacking precise and unified quantitative standards and scientific digital testing methods, resulting in the difficulty of accurately matching the individual needs of patients in terms of force, position and force line of the manufactured orthosis, and the adaptability is unsatisfactory.

[0003] The traditional method of adjusting the force position and force line mainly relies on manual cutting, rotation, translation and other rough operations on the negative shape (negative cavity) produced by the plaster bandage for the patient, and then fills it with plaster bandage. This method not only has low operation accuracy, but also low efficiency. It cannot achieve personalized and precise adjustment goals, and it is difficult to effectively deal with the various deformity types (such as C-type, S-type scoliosis, etc.), different degrees of curvature, different rotation angles and unique trunk morphology of patients. The resulting orthosis often has the problem of unreasonable local pressure distribution, which is very easy to cause local compression injury, manifested as skin ulcers, soft tissue damage, etc., causing additional pain to patients; unreasonable force lines may also lead to mechanical compensation, causing compensatory bending or rotation in other parts of the body, and even causing new scoliosis, further aggravating the condition; in addition, the patient's wearing comfort is greatly reduced, and the wearing tolerance is reduced, which directly affects the correction effect, resulting in unsatisfactory correction effect, poor clinical effectiveness, and difficulty in maintaining stable efficacy for a long time. Traditional technologies also have serious defects in data management. Patient data is not effectively preserved, and the treatment process cannot be fully traced and scientifically evaluated at a later stage. It is difficult to optimize and adjust the treatment plan based on the individual patient's condition. The overall treatment process lacks systematicity and scientificity.

[0004] The adjustment of the force position and force line of the scoliosis orthosis is crucial to achieve effective correction and protect the health of the patient. From the perspective of force position, accurate force position setting can accurately focus the correction force on the key areas that need to be corrected (such as the convex side) according to the specific situation of the patient's scoliosis, while cleverly releasing the key parts (such as internal organs) to avoid overpressure affecting breathing, thereby optimizing the mechanical distribution and laying the foundation for the gradual correction of the spine. A reasonable force line is like a navigation lighthouse, which determines the direction and actual effect of the corrective external force, and guides the spine to gradually return from abnormal shape to normal anatomical position, which is a key factor in alleviating scoliosis.

[0005] Given that the deformity characteristics of each patient are highly personalized, including unique deformity types, varying degrees of curvature, different rotation angles, and complex and diverse trunk morphology, traditional fixed-design orthoses obviously cannot meet the needs of personalized treatment. Only by dynamically adjusting the force position and force line can we tailor an accurate correction plan for each patient, ensure that the orthosis fits the patient's body perfectly, and improve the success rate of correction. If the force position and force line are improperly adjusted, a series of serious consequences will occur. Local compression injuries not only cause physical pain to patients, but may also cause complications such as skin infections, prolonging the treatment cycle; mechanical compensation may cause new spinal deformities, making the condition worse; patients reduce compliance due to discomfort, which directly affects the realization of the correction effect. In addition, while correcting scoliosis, the orthosis must take into account the patient's daily activity function, such as ensuring normal chest breathing movement and maintaining normal cardiopulmonary function. As the patient grows and develops, the spinal morphology continues to change, and the dynamic adjustment of the force position and force line becomes an inevitable requirement. Otherwise, the fixed-design orthosis will gradually attenuate the correction effect or even lose its effect due to its inability to adapt to body changes.

[0006] In recent years, digital technology has flourished in the field of medical rehabilitation, bringing unprecedented opportunities for the optimization and upgrading of scoliosis orthoses. To this end, whether it is possible to use computers to accurately simulate and optimize the force, position and force line of the orthosis in a virtual environment, predict the correction effect in advance, and greatly reduce the trial and error in the actual production process. It provides strong support for the formulation of comprehensive and personalized rehabilitation treatment plans. However, although digital technology has made certain progress, it still faces many technical bottlenecks and challenges in the dynamic adaptation and adjustment of the force, position and force line of scoliosis orthoses. Current technology is still difficult to fully meet the changing needs of patients during their growth and development. How to achieve real-time and accurate matching of the force, position and force line of the orthosis with the patient's dynamically changing physical condition is still a key problem that needs to be overcome, which also highlights the urgency of further in-depth research and innovation. Therefore, realizing the dynamic adaptation and adjustment of the digital force, position and force line is the core of improving the treatment effect of scoliosis orthoses and ensuring the long-term efficacy and quality of life of patients. It is also the current research hotspot and development direction in the field of scoliosis rehabilitation. Summary of the invention

[0007] In view of the shortcomings in the current technical field, the purpose of the present invention is to propose a digital force, position and force line dynamic adaptation adjustment method for a scoliosis orthosis. The present invention aims to overcome the many defects of traditional scoliosis orthosis in manufacturing and force, position and force line adjustment, and utilize digital technology to achieve a more accurate, personalized and dynamically adaptive force, position and force line adjustment method for scoliosis orthosis, so as to improve the correction effect of the orthosis, reduce side effects on patients, and improve the quality of life of patients.

[0008] To achieve the above object, the technical solution adopted by the present invention is: a method for dynamic adaptation and adjustment of digital force position and force line of a scoliosis orthosis, comprising the following steps:

[0009] 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;

[0010] 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;

[0011] 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;

[0012] 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;

[0013] 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, the specific parts including the chest and pelvic horizontal planes are rotated to parallel; including rotating specific parts such as the chest, waist 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;

[0014] 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;

[0015] 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.

[0016] Furthermore, the specific operation modes of various dynamic transformations are as follows:

[0017] 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;

[0018] 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;

[0019] 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.

[0020] 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;

[0021] 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;

[0022] Furthermore, the calibration line generation during the rotation operation can automatically adjust the number, position and angle of the calibration lines according to the patient's scoliosis type and severity to provide a more targeted rotation reference and ensure the accuracy and effectiveness of the rotation adjustment.

[0023] Furthermore, the standard three-dimensional bone model library in the personalized bending operation contains standard models of various ages, genders and bone development stages, and the model data can be updated in real time based on the latest medical research results and clinical experience to provide a reference basis that best suits the patient's actual situation.

[0024] Furthermore, the software interface during the expansion operation provides a real-time pressure distribution visualization function to intuitively display the changes in skin pressure during the model expansion process, helping the operator to more accurately adjust the expansion amplitude and direction according to the pressure distribution.

[0025] The present invention adopts the above technical solution, which has at least the following beneficial effects:

[0026] 1. Accurate correction of scoliosis: The present invention uses a high-precision 3D scanner to obtain a 3D model of the patient's torso, which can accurately present various detailed features of scoliosis and provide an accurate data basis for subsequent adjustments. In the model section division and dynamic model transformation operations, targeted adjustments can be made according to individual differences of patients, such as precise translation, rotation, bending, elongation, shortening and expansion operations, so that the force position and force line of the orthosis are highly consistent with the actual deformity of the patient's spine, achieving accurate correction. Whether it is a complex C-type or S-type scoliosis, or varying degrees of bending and rotation, it can be effectively handled, significantly improving the correction success rate and improving the patient's spinal morphology.

[0027] 2. Improve patient comfort and tolerance: The digital force position and force line adjustment method avoids the problem of unreasonable force position and force line caused by manual operation in traditional processes. During the adjustment process, simulation and optimization can be used to make the orthosis fit the patient's body evenly, effectively disperse the pressure, and avoid local compression injuries, such as skin ulcers and soft tissue injuries. Reasonable design can also ensure the patient's activity function when wearing the orthosis, such as normal chest breathing activity, spinal activity, etc., reduce the discomfort caused by the restriction of the orthosis, thereby improving the patient's wearing comfort and tolerance for long-term wearing, and ensuring the smooth progress of corrective treatment.

[0028] 3. Prevent complications and secondary injuries: Accurate force position and force line adjustment can follow the principles of human biomechanics and ensure that the application of corrective force is scientific and reasonable. Avoid mechanical compensation caused by improper force line, prevent compensatory bending or rotation in other parts, and reduce the risk of new scoliosis. At the same time, reasonable pressure distribution can reduce adverse effects on the spine and surrounding tissues, protect the patient's spinal health, prevent various complications and secondary injuries caused by wearing orthotics, and ensure the overall health of the patient.

[0029] 4. Adapt to the patient's growth and achieve dynamic adjustment: The spinal morphology of adolescent scoliosis patients changes continuously during their growth and development. The dynamic adaptation adjustment method of the present invention can track these changes in real time. By regularly acquiring new three-dimensional model data, the force position and force line of the orthosis are adjusted in time according to the patient's growth, ensuring that the orthosis always matches the patient's physical condition and continuously exerts the best correction effect, avoiding the reduction of correction effect or loss of adaptability caused by fixed design, and providing patients with continuous and effective spinal support and correction during their growth.

[0030] 5. Optimize clinical treatment process and effect: The application of digital technology makes the orthosis production and adjustment process more efficient and accurate. The acquisition of three-dimensional models is fast and convenient, and the model adjustment operation is flexible and accurate, which reduces the trial and error process in traditional processes and shortens the production cycle. At the same time, it is convenient for the storage, management and sharing of patient data, which is conducive to the collaboration of multidisciplinary teams such as clinicians, orthotists, and rehabilitation therapists to jointly develop more scientific and personalized treatment plans, improve the overall clinical treatment effect, and promote technological progress in the field of scoliosis rehabilitation treatment.

[0031] 6. Promote rehabilitation and improve quality of life: Taking into account the above advantages, patients can obtain better correction effects, higher comfort and less risk of complications during the treatment of the orthosis of the present invention, which helps to promote physical rehabilitation. The improvement of body shape and the recovery of function enable patients to participate more actively in daily activities, such as learning and sports, reduce the psychological pressure and social barriers caused by scoliosis, comprehensively improve the quality of life of patients, and help patients better return to normal life and social activities.

[0059] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. 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.

[0060] Scoliosis is a disease in which the spine is deformed in three dimensions, and it often occurs during the growth and development stage of adolescents. As an important treatment method, scoliosis braces provide external support to assist in correcting or controlling the degree of scoliosis and prevent the disease from worsening. They provide a non-surgical treatment option for adolescent patients, which can effectively slow down or even prevent the development of spinal curvature and reduce the need for surgical treatment.

[0061] The adjustment of the force position and line of force of the scoliosis orthosis is crucial. From the perspective of force position, the reasonable setting of force position can change the mechanical distribution of the spine, accurately apply pressure to the area to be corrected (such as the convex side), and avoid excessive pressure on the internal organs. The line of force determines the direction and effect of the external force. The ideal line of force can guide the spine from the abnormal state to the normal anatomical position, thereby alleviating scoliosis. Given the uniqueness of each patient's deformity, such as the type of deformity (C-type or S-type scoliosis, etc.), degree of curvature, rotation angle, and trunk morphology, personalized adjustment of the force position and line of force becomes the key to achieving precise correction and meeting the specific needs of patients. Improper adjustment may cause many problems. For example, local compression injury can cause skin ulcers and soft tissue damage; incorrect line of force may cause mechanical compensation, resulting in compensatory bending or rotation in other parts, and even new scoliosis; unreasonable pressure distribution will reduce the patient's tolerance to wearing and affect the correction effect. At the same time, when correcting scoliosis, the orthosis must also take into account the patient's activity function, such as the normal breathing activity of the thorax, otherwise it may affect the cardiopulmonary function. Considering the long-term nature of scoliosis correction and the constant changes in the patient's spinal morphology during growth and development, dynamic adjustment of force position and force line is indispensable. It can avoid the correction effect decreasing over time or losing adaptability due to fixed design, and ensure long-term efficacy and stability.

[0062] Based on the complexity of individual differences among patients, the present invention designs operations such as translation, rotation, bending, elongation, shortening, and expansion at various angles and dimensions. These operations are intended to fine-tune the orthosis from multiple aspects according to the specific deformity conditions of different patients, so as to achieve the best correction effect, enable the orthosis to fit the patient's spinal morphology closely, provide accurate and effective correction force, meet diverse treatment needs, minimize adverse effects on patients, and promote the patient's recovery process. The specific implementation methods of the present invention will be described in detail below.

[0081] This embodiment describes in detail a method for dynamic adaptation and adjustment of the force, position and force line of a scoliosis orthosis. First, a three-dimensional model of the patient's trunk is obtained, which comprehensively covers the surface morphology, bone structure and various characteristic information of the patient's trunk and scoliosis, laying the foundation for subsequent adjustment. Then, multiple cross sections are divided according to the key nodes and regional characteristics of scoliosis in the digital software, and adjustment points with clear functions are set at both ends of the cross section to achieve accurate positioning and transition control of the adjustment part. Then, a variety of dynamic transformation operations are performed on the selected cross-sectional part, including translation, rotation, personalized bending, adaptive elongation and shortening, and expansion operations. Each operation has its specific implementation method and can be dynamically adjusted according to the patient's real-time data and needs. At the same time, a calibration line is set according to the patient's real-time imaging data, and its number, position and shape can be automatically optimized, can be displayed / hidden and highlighted, and can be aligned with the three-dimensional model with high precision and the relevant parameters can be adjusted in real time. In addition, steps such as real-time rotation adjustment, horizontal calibration and sagittal plane dynamic optimization adjustment are also involved to ensure that the adjustment of the orthosis in various dimensions meets the individual needs of the patient.

[0082] The production of traditional scoliosis braces relies on plaster bandage molding and manual adjustment of force lines, and the process parameters are fuzzy, making it difficult to accurately adapt to individual differences in patients. This embodiment uses digital technology to obtain accurate three-dimensional models and make fine adjustments, solving the problem of inaccurate traditional processes and the inability to customize them.

[0083] Traditional methods are difficult to ensure that the force position and force line of the orthosis are reasonable, which can easily lead to local compression, mechanical compensation and patient discomfort. This embodiment optimizes the force position and force line through multiple dynamic transformation operations and precise calibration line settings, avoiding a series of problems caused by improper force position and force line.

[0084] The spinal morphology of adolescent patients changes during their growth and development, and traditional fixed-design orthoses cannot adapt. The dynamic adaptation adjustment method of this embodiment can track the growth changes of patients in real time and adjust the orthosis in time, solving the problem that traditional orthoses cannot be dynamically adjusted with the growth of patients.

[0085] Embodiment 2

[0086] This embodiment describes in detail a specific implementation scheme of a method for dynamic adaptation and adjustment of a scoliosis orthosis digital force position and force line, and the specific steps are as follows:

[0087] Step S1: 3D model acquisition

[0088] Advanced 3D scanning technology is used to obtain a 3D model of the patient's torso. This model must have a high degree of accuracy and completeness to accurately present the actual shape of the patient's torso, including surface contours, bone structure, and detailed features of scoliosis, such as the specific type of deformity (whether it is the common C-type or S-type scoliosis, or other complex types), the exact degree of curvature, the precise rotation angle, and the unique torso shape, thereby providing a solid data foundation for subsequent adjustment work.

[0089] Step S2: Model section division

[0090] On the digital 3D technology software platform, the acquired 3D model is intelligently divided into multiple sections based on the key structures and characteristic areas of the patient's scoliosis. The number of sections is not fixed, but can be flexibly set according to the actual situation of the individual patient and the adjustment needs. Both ends of each section are equipped with "adjustment points" with special identification and key functions. These adjustment points play a vital role in the entire adjustment process. They can not only accurately determine the parts that need to be adjusted, but also effectively control the transition form between the adjustment part and the fixed part, providing key positioning and control basis for subsequent precise operations.

[0091] Step S3: Model transformation operation

[0092] The part of the model covered by the adjustment points at both ends of the selected section is the "target adjustment" area, while the unselected part remains fixed. When operating the selected section, the 3D model part contained therein can perform a variety of complex dynamic transformation operations based on the patient's real-time physiological data and the preset intelligent algorithm, including:

[0093] 1. Translation operation

[0094] First, in different view modes of the software interface (such as front view, top view, sagittal view, etc.), accurately select the adjustment point of the part that needs to be adjusted. At this time, the adjustment point will be displayed in a striking orange color in the software interface, such as Figure 2 and Figure 3 As shown, so that the operator can clearly identify it. Then, according to the patient's body data (such as the distribution of the body's center of gravity, muscle strength balance, etc.) and the correction target (such as adjusting the spine to an ideal neutral position or a specific correction position), the operator can manually or automatically drag the arrow along the corresponding coordinate axis to achieve accurate translation of the model in that direction. For example, when performing left and right translation operations, the model position is adjusted by dragging the red arrow; when translating in the sagittal plane, the three-dimensional skeleton is introduced as a reference. When it is found that the patient's trunk is not in a normal physiological curve in the sagittal plane, for example, the corresponding adjustment points of the pelvis, abdomen, back, etc. are selected, and the green arrow is dragged to translate it to the target position. In addition, the translation amount can be dynamically adjusted according to the patient's growth and development changes (such as height growth, bone morphology changes, etc.), treatment progress (such as correction effect evaluation results) and real-time feedback information (such as comfort feedback after the patient wears the simulated orthosis, real-time monitoring data of force position and force line, etc.), to ensure that each translation operation can achieve the best force position adaptation effect, so that the orthosis can accurately apply the correction force.

[0095] like Figure 4 , Figure 5 and Figure 6 As shown, open the reference scale, straighten the pelvis, and place the two vertical lines on both sides. Drag the red arrow to move the torso to the center of the vertical line to "straighten" the body, while using the background grid as an overall reference.

[0096] like Figure 7 , Figure 8 and Fig. 9 As shown, sagittal plane translation: After the introduction of the three-dimensional skeleton, it can be found that the patient's trunk is not in the normal physiological curve in the sagittal plane. At this time, select the adjustment point corresponding to the part that needs to be adjusted, such as the pelvic area, drag the green arrow, and translate it to the target position.

[0097] 2. Rotation operation

[0098] In the first step, the patient's body model is intelligently divided into multiple cross-sections, and multiple calibration lines with important reference value are automatically generated based on the patient's X-rays, pressure detection diagrams and other multi-source influencing data (the generation of calibration lines and related operations will be described in detail in step S4). The model is observed from multiple perspectives (such as front view and top view) to fully grasp the morphological characteristics and deformity of the patient's body. Next, the adjustment points of the target rotation area are selected. These adjustment points are usually located in the key parts that need rotation adjustment, such as the connection between the waist and pelvic areas. Finally, the white circle in the top view or other appropriate views is rotated so that the target area (such as the waist and pelvic area) and other reference areas are accurately aligned in parallel or meet the specific relative position relationship of the individual correction needs of the patient. During the rotation process, the system will dynamically optimize the rotation angle and direction according to the preset biomechanical model and correction strategy, combined with the patient's real-time status (such as current body posture, spinal stress, etc.), to ensure the accuracy and effectiveness of the rotation adjustment.

[0099] like Fig.10 As shown, the body is divided into multiple cross sections, and multiple calibration lines can be added according to influencing data such as X-rays, pressure detection diagrams, etc. (as described in step S4), so that the model can be observed from multiple perspectives, such as a front view and a top view.

[0100] like Fig.11 As shown, refer to the arrow pointing to the direction shown. After lighting the calibration line, as shown in the pelvis and waist in the figure below, for patients with deformed body shape, when the pelvis is straightened, it is easy for the waist area and pelvis to rotate relative to each other.

[0101] like Fig.12 As shown, refer to the arrow pointing to select the adjustment point of the target rotation area;

[0102] like Fig.13 As shown, rotate the top view white circle so that the waist and pelvic area are neutral (parallel)

[0103] 3. Bending operation:

[0104] First, a standard three-dimensional bone model that is highly matched with the patient's age, gender, and bone development stage is imported, and it is aligned with the marking position when the patient model is scanned with high precision to ensure the consistency of the two in spatial position and morphology. Based on the normal human spine physiological curve and the personalized correction plan formulated according to the patient's specific situation, the adjustment points of the target area are selected. These adjustment points are usually located in the key parts of the spinal curvature or areas that require special adjustments. Then, by adjusting the white circle in the software interface, the model can be accurately adjusted in this area. The degree of curvature can be adjusted in real time according to the dynamic changes of the patient's scoliosis (such as changes in the degree of scoliosis as treatment progresses, changes in spinal morphology during body growth, etc.), ensuring that adjustments are always made along the best correction path, so that the orthosis can adapt to the dynamic changes of the patient's spine and provide continuous and effective correction support.

[0105] like Fig.14 , Fig.15 and Fig.16 As shown, the arrow points to the area and the bending operation: import the standard 3D skeleton and align the markers during the model scan, and have a reference for the normal physiological curve; select the adjustment point in the target area; adjust the white circle for bending adjustment.

[0106] 4. Lengthening and shortening operations

[0107] Based on the real-time monitoring data of the patient's muscle growth (such as changes in muscle volume caused by increased or decreased muscle strength), bone development process (such as bone length growth, changes in bone structure), and dynamic changes in body posture (such as the impact of changes in body posture during daily activities on spinal morphology), the adjustment points of the parts that need to be adjusted are selected. The operator pulls the blue arrow in the software interface up or down to achieve adaptive elongation or shortening of the model in the corresponding direction. The amount of elongation or shortening is not fixed, but is automatically calculated and accurately adjusted by the software based on the real-time acquired data on dynamic changes in the body to ensure that the orthosis always maintains a good fit with the patient's body during the growth and change of the patient's body, providing sufficient correction force without affecting the patient's comfort and correction effect due to being too tight or too loose.

[0108] like Fig.17 , Fig.18 and Fig.19 As shown, stretch or shorten, select the adjustment point of the part to be adjusted, and pull the blue arrow up or down. Note: Since the original color cannot be displayed in the attached drawings, the red arrow, blue arrow, etc. in this embodiment uniformly refer to the arrows corresponding to the attached drawings.

[0109] 5. Expansion Operation

[0110] According to the elastic changes of the patient's body tissues (such as changes in muscle elasticity and skin elasticity with treatment and growth), the skin pressure distribution (obtained by simulating the skin pressure distribution after wearing the orthosis), and the correction needs (such as decompression adjustment for local pressure concentration areas), the adjustment points of the target area are selected. The operator drags the red or green square in the software interface to flexibly expand the model in the relevant direction. The expansion amplitude can be dynamically set according to the individual differences of the patients (such as different body tissue characteristics of different patients) and the treatment stage (such as different degrees of expansion adjustment may be required in the early and late stages of treatment). At the same time, according to actual needs, the operator can select the adjustment points of multiple sections at the same time to make unified and coordinated adjustments in a larger area to achieve overall optimization; or select the adjustment points on one side of the section for local fine adjustment, and accurately deal with problems in specific parts to ensure the perfect fit and effective correction of the orthosis and the patient's body.

[0111] like Fig. 20 , Fig.21 and Fig. 22 As shown, for the expansion operation, select the adjustment point of the target area and drag the red or green square to expand the model in the relevant direction.

[0112] Step S4: Calibration line setting

[0113] like Fig.23 and Fig.24 As shown in the figure, according to the patient's real-time imaging data (such as high-resolution X-rays, detailed CT scans, etc.), calibration lines are intelligently marked at the deformed parts. The number, position and shape of the calibration lines are not fixed, but can be automatically increased, optimized or adjusted according to the complexity of the patient's scoliosis (such as multi-segmental scoliosis, complex scoliosis and other complex conditions) and the correction needs (such as the need to focus on specific deformed parts). The calibration lines can be displayed / hidden in real time in the software interface, and the operator can flexibly control their display status according to actual operation needs, so as to observe the model more clearly and make adjustments. At the same time, the calibration lines can also be highlighted according to their importance and attention, highlighting the key calibration lines for the operator's key reference. When setting the calibration lines, the image data and the three-dimensional model are accurately aligned through advanced image recognition and high-precision registration technology to ensure a high degree of consistency between the two in spatial position and shape. The scaling ratio, transparency and other parameters of the image data can be adjusted in real time by the operator according to the observation and analysis requirements. For example, when observing subtle structures, the image can be magnified and the transparency can be appropriately increased to more accurately determine the position and direction of the calibration line, ensuring that the calibration line can accurately reflect the actual situation and dynamic changes of the deformed part in the three-dimensional space, providing a reliable reference for subsequent adjustment operations.

[0114] Serves as a reference "calibration line" for force position and alignment adjustment. Based on imaging data, such as patient X-rays, mark calibration lines on the deformed parts. The number of calibration lines can be increased as needed, and can also be displayed / hidden or highlighted to prepare for subsequent adjustments. Insert the patient's X-ray and align the X-ray with the model based on the bony landmarks during scanning. The scaling and transparency of the X-ray can be adjusted. Calibrate the reference lines according to design requirements. For example, for patients with scoliosis, the pelvis, lumbar vertebrae, thoracic vertebrae, axilla and other positions need to be marked. The same applies to other types of orthotics and prosthetic sockets. X-rays and calibration lines can be displayed and hidden at any time, and the calibration lines can be highlighted.

[0115] Step S5: Real-time rotation adjustment

[0116] Intelligent recognition technology is used to quickly and accurately select the deformed part. After selection, the deformed part is intuitively presented in the software interface in the form of a black dot turning into an orange dot, so that the operator can clearly confirm it. Then light up the calibration line, and use the calibration line as a real-time reference. According to the patient's immediate posture data (such as current body posture, spinal stress state, etc.) and correction goals (such as rotating specific parts to an ideal parallel position or a specific angle relationship), the specific parts (such as key parts such as the chest and pelvis) are rotated horizontally to precise parallelism or to achieve the expected relative angle relationship that meets the current treatment needs. During the rotation process, the system monitors the impact of the rotation operation on the spinal force line in real time to ensure that each step of the rotation adjustment meets the optimal force position and force line requirements, avoids force line deviation or new problems caused by improper rotation, and ensures that the adjustment effect of the orthosis can accurately act on the patient's spine to achieve effective correction.

[0117] Step S6: Scale offset adjustment

[0118] Two intelligent inductive vertical lines equipped with high-precision sensors are used and placed on both sides of the patient's body as a ruler. By real-time monitoring of the relative position relationship between the two sides of the body and the vertical lines, advanced data analysis technology is used to accurately detect the degree of deviation on both sides of the body. The data of the deviation degree can be accurate to the millimeter level, providing a reliable basis for subsequent precise adjustments. According to the patient's dynamic balance needs (such as the requirement to maintain body balance in different activity states), select some sections for deviation operations. The operator accurately controls the movement amount and direction of the section through the software interface. The movement amount can be accurately set, and the direction can be adjusted according to the actual deviation of the patient's body and the correction goal. Through these operations, the patient's body always maintains or returns to the best neutral position or target correction position during the treatment process, ensuring that the orthosis can provide patients with a comfortable wearing experience and effective correction support in various situations (such as standing, walking, sitting and other different activity states), improving the practicality and adaptability of the orthosis.

[0119] Step S7: Horizontal calibration

[0120] Select the adjustment points on one side of the cross section, which are usually located in key areas related to horizontal calibration, such as shoulders, hips, etc. The operator pulls the blue arrow in the software interface and uses the built-in intelligent algorithm and real-time feedback mechanism of the software to perform horizontal calibration operations. For example, when it is found that the patient has posture problems such as high and low shoulders, the high and low shoulders can be accurately adjusted in parallel by accurately adjusting the relevant adjustment points so that the patient's shoulders are at the same level. The accuracy of horizontal calibration can be automatically set according to the patient's body sensitivity (such as the patient's perception of changes in body posture) and correction requirements (such as the ideal posture standard determined according to the treatment plan) to ensure that the adjustment accuracy can meet the correction needs without causing discomfort to the patient due to excessive adjustment. During the patient's daily activities, the software can automatically adjust the parameters and strategies of horizontal calibration according to the patient's activity pattern (such as body shaking when walking, posture maintenance when standing, etc.) and posture habits (such as the direction and degree of habitual body tilt), so that the orthosis can adapt to the patient's body changes in real time, always maintain good adaptability and correction effect, and effectively improve the patient's body posture.

[0121] like Fig.25 and Fig.26 As shown, select a point on one side of the cross section and pull the blue arrow to perform horizontal calibration, such as parallel adjustment of the patient's shoulder height. This step is to ensure that the patient's posture can be adjusted correctly.

[0122] Step S8: Dynamic optimization of the sagittal plane

[0123] The model is rotated and translated in the sagittal plane to ensure that the adjustment of the orthosis in the sagittal plane can achieve the expected effect, such as making the human spine always conform to the normal physiological curve changes. The sagittal rotation and translation operations can automatically select the corresponding operation tools and control parameters according to the individual conditions of the patient (such as the patient's age, gender, bone development status, scoliosis type and degree, etc.) and treatment needs (such as the correction focus and goals determined according to the treatment stage). During the operation, referring to other relevant real-time data (such as the position and angle changes of the calibration line, the distribution changes of muscle strength in the sagittal plane, the dynamic changes of bone morphology in the sagittal plane, etc.) or model features (such as the morphological changes of the three-dimensional bone model in the sagittal plane), the software optimizes the adjustment strategy in real time based on these comprehensive information to achieve dynamic adaptability and accuracy of sagittal adjustment. For example, during the growth and development of the patient, as the length of the spine increases and the physiological curve changes, the sagittal adjustment can be followed up in time to ensure that the orthosis always matches the sagittal morphology of the patient's spine, providing a continuous and stable correction force, and promoting the normal development and correction of the patient's spine in the sagittal plane.

[0124] Sagittal rotation, translation, etc. This step is to ensure that the adjustment of the orthosis in the sagittal plane can achieve the desired effect, such as the physiological curve of the human spine, thereby improving the applicability and comfort of the orthosis. As in step 3 above, the instructions for translation, bending, etc.
