Description

Technical Field

[0001] This invention relates to the field of ankle and foot correction technology, and in particular to a calculation method for calculating the correction area and intensity of abnormal force lines in the lower limbs. Background Technology

[0002] The foot is an important part of the human musculoskeletal system. However, due to the influence of common factors such as abnormal muscle development or delayed motor function in many children and adolescents, lack of exercise or excessive exercise intensity, and poor posture, abnormal foot structure is becoming more and more frequent in adults. For example, acquired flat feet and pronation are also common.

[0003] Abnormal foot structure can lead to uneven pressure on the foot, causing pain when pressure is concentrated in a certain area of ​​the foot, and even causing changes in the foot structure. For example, flat feet is a common foot structural abnormality that often requires the use of orthotic devices for correction.

[0004] A search revealed that Chinese patent application number CN115444649A discloses a method for manufacturing foot orthotics and the foot orthotics themselves, which discloses a method for manufacturing an orthotics model by acquiring user foot data information.

[0005] Chinese patent application number CN101505691B discloses a foot deformity correction brace, which mentions the problem that existing correction devices have uncertain components that make it difficult to continuously correct deformities, and proposes to modify and design the correction device to solve the above problems.

[0006] However, in existing orthodontic methods, the design of the orthodontic scheme is selected based on empirical assessment after obtaining foot data, which has a large margin of error. The design process of the orthodontic scheme is difficult to standardize and make scientific, especially for the use of the orthodontic device. Because the orthodontic process is long and the correction is gradually improving, frequent replacement or design of new orthodontic devices is obviously too troublesome. How to scientifically determine the correction area and mechanical strength, and make personalized selections for the modification range and thickness of the orthodontic device to make the orthodontic device fit the actual situation of each individual user and ensure that the orthodontic device can continue to be effective, is a problem that needs to be addressed. Summary of the Invention

[0007] The purpose of this invention is to address the deficiencies in the existing technology by proposing a calculation method for calculating the correction area and intensity of abnormal force lines in the lower limbs.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A calculation method for determining the correction area and intensity of abnormal force lines in the lower limbs, and integrating the results of this method into the design of orthotic shoes, insoles, or braces, includes the following steps:

[0010] S1: Place the foot stably in a neutral position, measure the human body according to the structure of the ankle and foot and the modification requirements, and obtain the corresponding parameter data;

[0011] S2: Based on the parameter data and modification requirements obtained above, extract the corresponding modification calculation parameters to obtain the expected correction data;

[0012] S3: Import the data obtained above into the corresponding calculation templates, calculate the correction angle of the obtained parameters according to the preset, obtain the results, and establish a reference line;

[0013] S4: Based on the obtained calculation results, perform manual evaluation, combine the elastic strength and hardness of the material (considering changes in elastic modulus and prestress), fine-tune and determine the final parameters, make corresponding adjustments at the corresponding positions of the correction device, and complete the modification.

[0014] Furthermore, the specific process of step S1 is as follows:

[0015] S101: Fix the human body posture, adjust the foot position according to the human body height ratio, and record the best position, the worst feeling position and the habitual movement feeling position;

[0016] S102: Determine the parameter template for foot and ankle correction based on different locations;

[0017] S103: Obtain the measurement data of the modification parameters according to the parameter template.

[0018] Furthermore, in step S1, the modification parameter measurement data includes: foot width data and ankle height from the ground.

[0019] The measurement data can be obtained either manually or through any device capable of accurate measurement.

[0020] Furthermore, the specific process of step S2 is as follows:

[0021] S201: Establish a function calculation template, and use the above-obtained measurement parameter information to calculate the corresponding length and angle data;

[0022] S202: Based on the obtained length and angle results, calculate the correction angle to obtain the corresponding optimal correction prediction parameters;

[0023] S203: Match and compare the predicted correction parameters with the measured parameters, calculate the data on which the current parameters need to be changed to achieve the best predicted correction, and obtain the correction result.

[0024] Furthermore, in step S3, establishing a reference line specifically involves: establishing a standard line from the lower leg, ankle, and heel downwards based on the current measurement data. The standard line is located at the midline of the foot width, establishing a visual calculation reference line for visually judging the current foot data.

[0025] Following the steps above, establish a visual correction prediction reference line based on the correction prediction parameters, which is used to visually determine the final corrected foot data.

[0026] Furthermore, the specific process of modification and adjustment is as follows: mark nodes on the lower leg, ankle, and heel in sequence using the obtained reference lines;

[0027] Establish a horizontal reference line at the bottom of the feet, and use the intersections of each pair of reference lines with the horizontal reference line as new marker nodes;

[0028] The position and angle of adjustment required for the line segment to coincide between each pair of nodes of the visual correction prediction reference line and the visual calculation reference line are calculated using trigonometric functions.

[0029] Adjust the parameters to make the visual calculation reference line coincide with the visual correction expected reference line, record the changed parameter data, and record this parameter as the correction and modification parameter.

[0030] Compared to existing technologies, the advantages of this invention are as follows: it standardizes and scientifically improves the correction method based on empirical assessments with large errors, enables reasonable modification of the correction device, determines the optimal wedge correction range and thickness through trigonometric function calculations, and is applicable to different correction devices such as correction shoes / correction insoles / orthotics, so that they can all achieve the best biomechanical adjustment results, and can fit the continuous correction process, avoiding the increase in modification difficulty.

[0032] Figure 1 This is a flowchart illustrating the calculation method proposed in this invention for calculating the correction area and intensity of abnormal force lines in the lower limbs.

[0033] Figure 2 This is a schematic diagram illustrating an embodiment of the present invention. Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1

[0036] Reference Figure 1 A calculation method for determining the correction area and intensity of abnormal force lines in the lower limbs includes the following steps:

[0037] S1: Place the foot stably in a neutral position, measure the human body according to the structure of the ankle and foot and the modification requirements, and obtain the corresponding parameter data;

[0038] It should be noted that the parameter data includes foot width, foot length, foot thickness, shape of the center line from the lower leg to the heel, arch height, and foot ground clearance.

[0039] S2: Based on the parameter data and modification requirements obtained above, extract the corresponding modification calculation parameters to obtain the expected correction data;

[0040] It should be noted that the modification needs include different degrees of correction needs, such as complete correction and pain relief. The predicted correction data compares one or more of the above parameters with the standard parameters of the demand status, matching the same data and using different standard data as the predicted correction data.

[0041] S3: Import the data obtained above into the corresponding calculation templates, calculate the correction angle of the obtained parameters according to the preset, obtain the results, and establish a reference line;

[0042] It should be noted that the calculation template includes parameter categories such as foot width data, and includes calculation templates for parameter categories. By importing the corresponding parameters under the corresponding parameter categories, the result data can be quickly obtained through the calculation template.

[0043] S4: Based on the obtained calculation results, perform manual evaluation, combine the elastic strength and hardness of the material (considering changes in elastic modulus and prestress), fine-tune and determine the final parameters, make corresponding adjustments at the corresponding positions of the correction device, and complete the modification.

[0044] It should be noted that the strength and elasticity of the selected materials will affect the application of the corrective force, requiring a secondary, detailed assessment by a human.

[0045] It should be noted that manual assessment is used to make fine adjustments to meet the different definitions of modification needs. For example, if there is pain in a certain minor area, selective adjustments will be made without affecting other areas.

[0046] It should also be noted that the modification device includes orthotic shoes, orthotic insoles, and orthotics.

[0047] In a specific embodiment of this application, the specific process of step S1 is as follows:

[0048] S101: Fix the human body posture, adjust the foot position according to the human body height ratio, and record the best position, the worst feeling position and the habitual movement feeling position;

[0049] S102: Determine the parameter template for foot and ankle correction based on different locations;

[0050] S103: Obtain the measurement data of the modification parameters according to the parameter template.

[0051] In a specific embodiment of this application, in step S1, the modification parameter measurement data includes: foot width data and ankle height from the ground.

[0052] The measurement data can be obtained either manually or through any device capable of accurate measurement.

[0053] Example 2

[0054] Reference Figure 1-2 Based on Example 1, the specific process of step S2 is as follows:

[0055] S201: Establish a function calculation template, and use the above-obtained measurement parameter information to calculate the corresponding length and angle data;

[0056] S202: Based on the obtained length and angle results, calculate the correction angle to obtain the corresponding optimal correction prediction parameters;

[0057] S203: Match and compare the predicted correction parameters with the measured parameters, calculate the data on which the current parameters need to be changed to achieve the best predicted correction, and obtain the correction result.

[0058] As a preferred embodiment, the establishment of the reference line in step S3 is specifically as follows: the current measurement data is used to establish a standard line from the lower leg, ankle, and heel downwards. The standard line is located at the midline of the foot width. A visual calculation reference line is established for visually judging the current foot data.

[0059] Following the steps above, establish a visual correction prediction reference line based on the correction prediction parameters, which is used to visually determine the final corrected foot data.

[0060] The preferred modification and adjustment process is as follows: mark nodes on the lower leg, ankle, and heel in sequence using the obtained reference lines;

[0061] Establish a horizontal reference line at the bottom of the feet, and use the intersections of each pair of reference lines with the horizontal reference line as new marker nodes;

[0062] The position and angle of adjustment required for the line segment to coincide between each pair of nodes of the visual correction prediction reference line and the visual calculation reference line are calculated using trigonometric functions.

[0063] Adjust the parameters to make the visual calculation reference line coincide with the visual correction expected reference line, record the changed parameter data, and record this parameter as the correction and modification parameter.

[0064] To better understand the technical solution of this application, the following explanation is provided in conjunction with specific implementations.

[0065] like Figure 2 As shown, the details are as follows:

[0066] Place your feet flat on a flat surface;

[0067] Measure foot width and ankle height from the ground;

[0068] Establish a virtual plane from the heel, and then establish standard lines from the lower leg, ankle, and heel downwards. These standard lines are the actual reference lines for the lower leg, ankle, and heel.

[0069] Starting from the topmost point of the actual reference line, establish a standard line connecting the lower leg, ankle, and heel using standard parameters. This standard line serves as the expected correction reference line.

[0070] Using the point of intersection as the plane intersection point and the supporting plane as the horizontal plane, draw a horizontal reference line, and extend and correct the expected reference line and the actual reference line so that the three intersect;

[0071] Based on trigonometric functions, the angle, length, and curve required for the actual reference line to coincide with the expected correction reference line are obtained;

[0072] Following the steps above, replace the heel with the forefoot to obtain the angle, length, and curve data for forefoot correction;

[0073] Based on the obtained angle, length, and curve data, the shape of the orthotic shoe / orthotic insole / orthosis is modified, and the area and thickness of the bottom are modified.

[0074] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
