DETAILED DESCRIPTION

[0023] In order to make the invention purposes, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] It should be understood that the terms "comprise", "comprising", and other similar expressions in the specification or claims of the present application and the above drawings mean covering non-exclusive inclusion, such as a process, method or device, equipment comprising a series of steps or units, which is not limited to the listed steps or units. In addition, "first", "second" are used to distinguish different objects, and are not used to describe a specific order.

[0025] In the present embodiment, the core idea of the Rigo orthopedic brace design is to apply a correction force based on the biomechanical characteristics of the scoliosis patient to achieve multi-dimensional orthopedic control of the lateral curve. The Rigo orthopedic brace is designed according to a three-point pressure system, an anti-rotation mechanism, a pelvic regulation strategy, and an L4-L5 compensation state.

[0026] According to a first aspect of the present application, as shown in Figure 1 a personalized scoliosis brace automatic generation method based on a correction principle is provided, comprising: Step S1: According to the lateral deviation of the spine, a three-point pressure system is obtained along the extension direction of the spine, the three-point pressure system comprising a first auxiliary pressure zone, a main pressure zone and a second auxiliary pressure zone.

[0027] In some embodiments of the present embodiment, as shown in Figure 2 the three-point pressure system forms a stable mechanical triangular structure through the synergistic action of the main pressure zone and the auxiliary pressure zone.

[0028] A main pressure pad is arranged in the main pressure zone, and auxiliary pressure pads are arranged in the first auxiliary pressure zone and the second auxiliary pressure zone. The main pressure pad provides a force for the main pressure zone, and the auxiliary pressure pad provides a counterforce for the first auxiliary pressure zone or the second auxiliary pressure zone.

[0029] If the lateral deviation of the spine is in the thoracic region, the convex side ribs are pushed by the main pressure pad, and the concave side ribs are pushed by the auxiliary pressure pad.

[0030] If the lateral deviation of the spine is in the lumbar region, the convex pelvis and lumbar spine are pushed by the main pressure pad, the concave pelvis and lumbar spine are pushed by the auxiliary pressure pad, and the compensatory torsion of the lumbar region and the sacral region is limited by the sacrum fixation belt.

[0031] Specifically, the main pressure area is located on the convex side of the apex vertebra of the lateral curvature, and a directional pushing force is applied by the main pressure pad to reduce the lateral deviation of the spine. The first auxiliary pressure area and the second auxiliary pressure area are respectively distributed on the concave side of the upper end of the main curvature and the concave side of the lower end of the main curvature, for balancing the main pressure and preventing overcorrection of the spine. The distribution and strength of the pressure pads in each type need to be designed in consideration of the curve length, the position of the apex vertebra and the flexibility, for example, in the single lumbar type E1, the main pressure area is concentrated on the convex side of L1-L2, and the auxiliary pressure area extends to the concave side of the thoracolumbar junction to limit the compensatory thoracic deviation.

[0032] The positions of the first auxiliary pressure area and the second auxiliary pressure area determine the size and range of the moment of force during the correction process of the correction brace, and the three-point force design of the correction brace for different Rigo types is different: B1+B2 type adopts two sets of three-point pressure systems, respectively located in the chest and waist regions of the patient; the rest types only adopt a single set of three-point pressure system.

[0033] The three-point pressure system of the present embodiment cooperates with the first auxiliary pressure area, the main pressure area and the second auxiliary pressure area to form a stable mechanical triangular structure. The main pressure area applies a directional pushing force by the main pressure pad to reduce the lateral deviation of the spine, and the first auxiliary pressure area and the second auxiliary pressure area balance the main pressure by the auxiliary pressure pad and prevent overcorrection of the spine.

[0034] The main pressure area of the three-point pressure system can be determined by the position of the apex cone, and the calculation formula of the center positions of the first auxiliary pressure area and the second auxiliary pressure area is:

[0035] wherein, , corresponding to the Cobb angle and the weighting coefficient of the thoracolumbar curvature, respectively, which varies with A1, A2+A3, B1+B2, C1+C2, E1, E2 specific types, is the Cobb angle, is the thoracolumbar curvature.

[0036] Specifically, the center positions of the first auxiliary pressure area and the second auxiliary pressure area are numerical values with decimals, indicating the number of vertebral bodies away from the apex cone. When the adjustment amount is 3.6, the center positions of the first auxiliary pressure area and the second auxiliary pressure area are located about 3.6 vertebral bodies away from the apex cone.

[0037] In some embodiments of the present embodiment, the method for obtaining the Cobb angle is as follows: Draw a first parallel line corresponding to the upper endplate of the uppermost vertebral body and a second parallel line corresponding to the lower endplate of the lowermost vertebral body, respectively; Take the included angle between the first parallel line and the second parallel line as the Cobb angle corresponding to the thoracic curvature region or the lumbar curvature region; In some embodiments of the present embodiment, the method for obtaining the thoracolumbar curvature is as follows: If the lateral deviation of the spine is in the thoracic region, the thoracolumbar curvature is the thoracic curvature, and if the lateral deviation of the spine is in the lumbar region, the thoracolumbar curvature is the lumbar curvature.

[0038] Specifically, based on the target bounding box data corresponding to each thoracic vertebra, the vertebral body geometric center coordinates corresponding to each thoracic vertebra are obtained, transition points are inserted into adjacent vertebral body geometric center coordinates, and the vertebral body geometric center coordinates of all thoracic vertebrae and all transition points are fitted to obtain the thoracic curvature.

[0039] Based on the target bounding box data corresponding to each lumbar vertebra, the vertebral body geometric center coordinates corresponding to each lumbar vertebra are obtained, transition points are inserted into adjacent vertebral body geometric center coordinates, and the vertebral body geometric center coordinates of all lumbar vertebrae and all transition points are fitted to obtain the lumbar curvature.

[0040] Step S2: Obtain the anti-rotation force generation amount based on the Cobb angle and the distance between the thoracic apex and the transition point.

[0041] In the present embodiment, the anti-rotation mechanism achieves correction of spinal torsional deformity through the action of force couple of horizontal plane. The correction brace is provided with a main pressure pad on the back region on the convex side of the thoracolumbar apex and an auxiliary pressure pad on the corresponding position on the concave side, forming a pair of thrusts in opposite directions. The anti-rotation force in the thoracic region pushes the ribs on the concave side forward and the ribs on the convex side backward. The anti-rotation design in the lumbar region is achieved by adjusting the relative position of the pelvis and the lumbar vertebrae: in the main curvature of the lumbar vertebrae, the pelvis fixing part of the correction brace will apply a thrust in the opposite direction, and further limit the compensatory torsion of the lumbosacral region through the fixation of the sacral belt.

[0042] In some embodiments of the present embodiment, the anti-rotation force generation amount is obtained based on the Cobb angle and the distance between the thoracic apex and the transition point, and the calculation formula is as follows:

[0043] wherein, is the thoracic apex, is the transition point between the first thoracic vertebra and the second thoracic vertebra, is the thoracic apex and the transition point is the weighted coefficient of the distance difference; is the apex the number difference between the transition point .

[0044] In the formula, the application position of the anti-rotation couple is located at the horizontal plane of the top cone, and it is necessary to move the main three-point force area to the obliquely rear side in the horizontal plane, while applying another anti-rotation force at the corresponding position on the opposite side, and the two work together to offset the torsion effect of the spine. The determination of the anti-rotation adjustment amount is determined by the Cobb angle and the distance between the top cone of the thoracic curve and the transition point, and the basic rear movement reference is 30°.

[0045] Step S3: Based on the lower end cone of L4 and the upper end cone of L5 and the transition point, the pelvic fixation control amount is obtained.

[0046] In this embodiment, the Rigo orthotic concept emphasizes the dynamic balance between the head, trunk and pelvis. The patients of type A1, A2+A3 have the pelvis displaced to the concave side of the thoracic vertebrae, so the design of the orthosis emphasizes the relative opening or overcorrection of the pelvis to restore the overall balance state; the patients of type B1+B2 have the pelvis displaced to the convex side of the thoracic vertebrae, and the opening or closing of the pelvis side needs to be selected according to the specific situation; the patients of type C1+C2 have the pelvis in the middle position and do not need additional significant adjustment; the types E1 and E2 are short orthoses applied to the lumbar vertebrae and the lumbar region respectively, and the overall balance is ensured through the reverse translation of the pelvis and the corresponding region.

[0047] In some embodiments of the present embodiment, the pelvic fixation control amount is determined according to the included angle of the lower end cone of L4 and the upper end cone of L5 relative to the horizontal plane, and the difference in serial number between the top cone of the lumbar curve and the transition point, and the pelvic fixation control amount is obtained based on the lower end cone of L4 and the upper end cone of L5 and the transition point. The calculation formula is:

[0048] Wherein, and respectively represent the included angle of the lower end cone of L4 and the upper end cone of L5 relative to the horizontal plane; is the weighted coefficient of the average value of the included angle of the lower end cone of L4 and the upper end cone of L5 relative to the horizontal plane, is the top cone of the lumbar curve, is the transition point between the first thoracic vertebra and the second thoracic vertebra, is the weighting coefficient of the lumbar curvature in the pelvic fixation control, and the pelvic fixation control amount is the degree required for the sacrum to return to the horizontal state in the clockwise direction.

[0049] Step S4: Based on the lower end cone of L4 and the upper end cone of L5, the L4-L5 compensation state is obtained.

[0050] In this embodiment, the L5 inclination amplitude is less than the L4 positive compensation, and the lumbar pressure pad is combined with three-point force to jointly inhibit compensation; L5 and L4 are horizontal for negative compensation, and need to be combined with pelvic regulation, such as C1+C2 type only needs to fix the pelvis, and A3 type needs to increase the pressure pad above the sacrum to promote the lumbar spine to be positive.

[0051] In some embodiments of the present embodiment, the L4 lower end cone and the L5 upper end cone are used to obtain the L4-L5 compensation state, including: The angles of the L4 lower end cone and the L5 upper end cone relative to the horizontal plane are obtained, and if the difference between the two angles is less than the difference threshold, the L4-L5 compensation state parameter is positive compensation, and if the difference between the second angle and the third angle is greater than or equal to the difference threshold, the L4-L5 compensation state parameter is negative compensation.

[0052] Through the comprehensive action of the above four biomechanical principles, the Rigo orthopedic brace can provide personalized and precise treatment plans for patients with different types of scoliosis, and has shown good correction effect in clinical practice.

[0053] Step S5: Based on the three-point pressure system, the anti-rotation force generation amount, the pelvic fixation regulation amount, and the L4-L5 compensation state, a correction brace is designed.

[0054] In one specific embodiment, a three-dimensional model of a patient is taken as an example, and a correction brace of B1+B2 type Rigo classification is used for the patient, and two groups of three-point pressure systems are used, which are located in the chest and waist regions of the patient, as shown in Figure 3 The correction opinion generated by the personalized scoliosis brace automatic generation method based on the correction principle provided in the present embodiment is shown in

[0055] Figure 3 In the middle, two groups of three-point auxiliary orthopedic forces are added at T5, T11 and T12, L4 bones, and the main orthopedic forces of three-point forces are added at T9 and L2 bones at 45° and 41°, and the anti-rotation force is applied on the opposite side of the horizontal plane.

[0056] Figure 4(a) shows an example of local deformation; Figure 4(b) shows an example of hole digging, which adds a release area on the opposite side of the initial three-point force main pressure area; Figure 4(c) shows an example of curved surface cutting, and the final orthopedic brace model is obtained after local deformation, hole digging, and curved surface cutting.

[0057] The calculation formula of each parameter of the personalized scoliosis brace automatic generation method based on the correction principle provided in the present embodiment is based on the Rigo classification, and the weighted coefficient dedicated to each classification is determined combined with the classification result of the gradient fuzzy decision tree, so as to ensure that the brace design can match the biomechanical characteristics of the patient.

[0058] The construction method of the orthopedic feature formula is as follows: 30 X-ray image data of each type completely meeting the Rigo classification standard are selected, and 12 parameters extracted from the data by the recognition technology based on YOLOv11 are used. Considering that the mixing of quantitative and qualitative data may affect the classification efficiency, the two are divided into independent data groups. The conventional CART decision tree algorithm is used to train the standard classification data, and the first three nodes of the optimal split in the decision tree are extracted as the main features of the quantitative group and the qualitative group. After multiple experiments, Cobb angle, thoracic curvature and lumbar curvature are selected as the three quantitative features, and Tp point, L4-L5 compensation state and lumbar top cone are selected as the three qualitative features. The orthopedic parameter formula is constructed based on the above six features, and the weighting coefficients in the formula are determined by orthopedic experts according to long-term clinical experience.

[0059] Therefore, the embodiment applies a correction force based on the biomechanical characteristics of the scoliosis patient to achieve multi-dimensional orthopedic control of the scoliosis curve. Through the comprehensive action of the three-point pressure system, the anti-rotation force generation amount, the pelvic fixation regulation amount and the L4-L5 compensation state, the Rigo orthopedic brace can provide a personalized and precise treatment plan for different types of scoliosis patients and has shown good correction effect in clinical practice.
