Description

Technical Field

[0001] The invention belongs to the field of medical orthopedics, and in particular relates to a method for customizing orthopedic insoles that can be diagnosed, designed and produced. Background Art

[0002] Many foot diseases (flat feet, diabetic foot, hallux valgus, etc.) can be treated / relieved by wearing orthotic insoles.

[0003] For foot diseases, patients can wear orthotic insoles to achieve a therapeutic / corrective effect.

[0004] Mass-produced insoles do not meet individual patient requirements and may have a counterproductive effect.

[0005] Custom insoles are designed to vary based on the individual patient.

[0006] Generally, the customization of insoles can be divided into three steps: 1. Patient data collection (basic information, biological information), 2. Data-based design, and 3. Design-based manufacturing.

[0007] From the perspective of data collection, there are problems with tissue deformation / morphological loss; the forces applied at various locations on the sole of the foot also determine the softness and hardness of the insole, and the collection of sole pressure is also essential; after collection, the data are mixed together, lacking classification and diagnosis due to disease or individual, such as diabetic foot and flat feet.

[0008] From a design perspective, the collected data is not directly used in the design, and the design is done manually / experience-based; before it is manufactured, it is impossible to verify whether the design is correct.

[0009] From a manufacturing perspective, there are no individual differences in mass-produced insoles; some customized insoles are made by hand-polishing and other methods, which do not involve the scientific design mentioned above.

[0010] The invention patent application with the application publication date of 2024.02.27 and application publication number CN 117598565 A discloses "a method for customizing plantar orthotic insoles based on multimodal evaluation technology in weight-bearing position". Its technical solution performs multimodal mechanical testing on the plantar soft tissue, and the obtained viscoelastic data of the internal soft tissue of the foot helps to accurately diagnose foot diseases. The evaluation technology based on the foot morphology and plantar pressure data under real working conditions and the medical expert database standards can achieve more accurate and reliable foot disease evaluation, and provide more professional test reports and correction plans. However, during the implementation process, it was found that among the equipment involved, the multimodal detection equipment, the flexible interactive detection equipment, and the plantar mimicry simulation equipment were all used for data collection, but the collection content and order were different. Due to the large number of collection equipment required, the implementation cost is relatively high, which is not conducive to the manufacture and personal customization of customized insoles based on individual patients; and it is necessary to manually reconstruct the acquired data during the design stage and import it into the software for design, which requires high operating experience and practical hands-on ability of the operator, and is not conducive to the manufacture and personal customization of customized insoles; in addition, the technical solution also has the phenomenon of data circulation (repeated verification during the design stage), the operation is relatively complicated, and the manufacturing link is completely ignored, which is not convenient for ordinary medical workers to participate and implement.

[0011] In actual work, how to improve the scientific nature of each step from the three perspectives of data collection, design, and manufacturing is a practical technical problem that needs to be solved urgently in actual work. Summary of the invention

[0012] The technical problem to be solved by the present invention is to provide a method for customizing orthopedic insoles that can be diagnosed, designed, and produced. It starts from the three perspectives of data collection, design, and manufacturing to improve the scientificity of each step; in the collection stage, a lot of biological information can be collected, and other equipment such as X-ray machines can also be used to collect more information, and the condition (diabetic foot, flat feet, etc.) can be grouped and diagnosed at the same time; in the design stage, different design schemes are generated based on the condition and implemented on the equipment (the push rod moves up and down), and biological information (such as the sole pressure after the push rod moves up and down) is obtained in real time to judge the treatment effect; in the manufacturing stage, a 3D printing method is used to achieve stiffness matching of the final design effect.

[0013] The technical solution of the present invention is to provide a method for customizing orthopedic insoles that can be diagnosed, designed, and produced, which is characterized by comprising the following steps:

[0014] A. Data Collection:

[0015] A1. Collection:

[0016] Use "foot testing equipment based on lifting matrix" to collect various routine bio-information data of normal people and patients with different foot diseases;

[0017] The conventional biological information includes at least three dynamic / static data including static plantar contour, plantar pressure, and force line;

[0018] A2. Processing data:

[0019] The various routine biometric data collected by the "foot test device based on the lifting matrix" are grouped and trained by artificial intelligence to enable it to have diagnostic capabilities; the details are as follows:

[0020] A2.1. Experts diagnose and confirm normal people and patients; register basic information including age, gender, BMI value and various conventional biometric data, group the data according to age, gender, BMI value and condition, and train the large model Ai;

[0021] A2.2. After the large model Ai training is completed, after registering the tester's basic information and collecting various biological information, a diagnosis can be made: whether the patient is sick and what disease the patient has;

[0022] B. Design:

[0023] B1) Correction:

[0024] Then the large model Ai training mentioned in data collection can not only diagnose the condition, but also autonomously exercise to temporarily correct the foot problem;

[0025] B2) Insole contour:

[0026] The final height of each electric actuator in the lifting matrix of each lifting matrix foot test device after lifting represents the center of its area, thereby generating the insole contour;

[0027] B3) Softness and hardness design:

[0028] During the lifting process of the lifting matrix, each electric push rod has displacement and collected force, which can know the different positions of the insole, the appropriate hardness, that is, the appropriate material density;

[0029] Using the pattern of "method for preparing orthopedic insoles", further generating designs of orthopedic insoles;

[0030] At this point, the insole design is complete;

[0031] C. Manufacturing:

[0032] The manufacturing process focuses more on the design stage, and manufacturing emphasizes uploading the design to the cloud and automatically sending it to 3D printing manufacturing.

[0033] Specifically, the method for customizing orthopedic insoles that can be diagnosed, designed, and produced improves the scientific nature of each step from the three perspectives of data collection, design, and manufacturing; in the collection stage, a lot of biological information is collected, and more information can also be collected in conjunction with other equipment, while grouping and diagnosing the condition; in the design stage, different design schemes are generated based on the condition and implemented on the equipment, and biological information is obtained in real time to judge the treatment effect; in the manufacturing stage, a 3D printing method is used to achieve the design of the optimal orthopedic insole and achieve stiffness matching for the final effect.

[0034] Specifically, the "liftable matrix foot testing device" can obtain dynamic / static data while obtaining the soft tissue characteristics of the foot. The soft tissue characteristics of the foot include elastic modulus and bone movement trajectory, and it records the soft tissue characteristics of the foot in real time.

[0035] Specifically, after the Ai training is completed, after registering the basic information of the tester and collecting various biological information, diagnosis can be performed while collecting data.

[0036] Furthermore, the “foot testing device based on a lifting matrix” at least includes a base, an electric push rod, a camera, a laser locator and a control host;

[0037] The base is a groove-shaped structure with side walls, used to accommodate a single foot of the person being tested;

[0038] In the groove-shaped structure, a group of electric push rod matrices composed of a plurality of electric push rods is arranged;

[0039] Each of the plurality of electric push rods is provided with a displacement sensor for measuring and providing a lifting height or lifting stroke of the push rod of the electric push rod;

[0040] A force sensor is arranged under each electric push rod to measure the pressure on the sole of the foot borne by each electric push rod;

[0041] A camera is installed on the left and right sides of the base groove respectively, for capturing the image of the foot of the test subject in real time and transmitting the image to the control host;

[0042] At the rear of the base, a laser locator is provided for emitting a green line laser beam vertically and horizontally to the ground to the Achilles tendon of the foot of the person being tested;

[0043] The control host is used to control the lifting height of each electric push rod and obtain the pressure feedback data of each push rod in real time;

[0044] At the same time, the control host calculates the inversion and valgus angles of the left or right foot based on the relative angle relationship between the laser beam and the Achilles tendon;

[0045] The control host is internally integrated with an FGPA control unit, which processes the feedback data of each electric linear actuator in the electric linear actuator matrix and transmits it to the control host through row and column scanning and signal processing circuits;

[0046] The software system in the control host controls the longitudinal displacement of each push rod in real time by detecting the output data of each displacement sensor, so as to control the shape of the sole of the tested person, and accurately displays the force condition of the sole under the shape by reading the data of the stress sensor;

[0047] The foot testing device based on the lifting matrix realizes the pushing of different parts of the sole of the testee's foot by controlling the pushing force applied to each electric push rod; measures the pressure data of the corresponding points on the sole of the testee's foot by controlling the different lifting heights of each electric push rod; compares the measured foot shape and pressure data of each point on the sole with the standard or conventional normal foot shape and sole pressure data, so as to obtain the lifting height required for different parts of each foot of the testee and the pressure they need to withstand; and then formulates a personalized correction plan of "private customization" nature for individual testees of different ages and different symptoms to ensure the consistency of the foot shape and sole pressure of the testee.

[0048] Furthermore, the "foot testing equipment based on the lifting matrix" synchronously obtains the foot shape and multi-point plantar pressure data by setting and controlling multiple electric push rods arranged in a matrix, and obtains the corresponding plantar pressure while changing the foot shape, thereby ensuring the consistency of the foot shape and plantar pressure; it can adapt to different ages, different symptoms, and different populations and accurately collect foot shapes and plantar pressures, simulate foot usage scenarios in various daily scenarios, and the collected foot shape and plantar pressure data can directly guide the design of orthopedic insoles; it can effectively solve the problems existing in existing foot testing equipment and provide more accurate, real-time and reliable technical support for the diagnosis and treatment of foot health.

[0049] Furthermore, the "method for preparing orthopedic insoles" comprises the following steps:

[0050] 1) Data collection:

[0051] 1.1) Collecting plantar contour information and plantar pressure information;

[0052] 2) Design:

[0053] 2.1) Prepare the insole shape using the plantar contour information;

[0054] 2.2) Project the sole pressure onto the insole;

[0055] 2.3) Divide the insole into different areas according to different plantar pressure distribution;

[0056] 2.4) Performing lattice processing;

[0057] 2.5) Provide smooth transition between different areas;

[0058] 3) Manufacturing:

[0059] 3.1) 3D printing machine selection;

[0060] 3.2) Convert the insole after gentle transition processing into a file recognizable by a 3D printer;

[0061] 3.2) Use 3D printing to obtain orthopedic insoles with a smooth transition of softness and hardness between different areas.

[0062] Furthermore, the "method for preparing orthopedic insoles" uses the measured plantar pressure distribution map as a reference, and divides the insole into different areas according to the plantar pressure distribution, so as to achieve arbitrary partitioning of different pressure ranges; by crystallizing the insole, the adjustment of different stiffnesses at the partition positions is achieved; the fitting rod lattice and the surface lattice are smoothed, the rod diameter and the surface thickness are changed, so as to achieve the purpose of smooth transition between different areas, which helps to manufacture orthopedic insoles that meet user customization needs, have different hardnesses at different positions, and have a smooth transition between different hardnesses, and are comfortable to wear.

[0063] Specifically, in the method for customizing orthopedic insoles that can be diagnosed, designed, and produced, the production of the orthopedic insoles is divided into three major stages: data collection, design, and manufacturing; the three steps can be completed, or a step can be stopped at any time to achieve different technical effects.

[0064] Furthermore, the different technical effects include:

[0065] If only data collection is implemented, the cause can be diagnosed;

[0066] When it comes to the design stage, it can be used to predict the expected recovery effect of the corresponding disease.

[0067] Compared with the prior art, the advantages of the present invention are:

[0068] 1. The technical solution of the present invention can complete all the collection work by using only one set of lifting matrix foot testing equipment, which improves the scientificity of each step from the three perspectives of data collection, design and manufacturing;

[0069] 2. The technical solution of the present invention allows the design of orthopedic insoles to be done directly on the foot testing device of the lifting matrix during the design stage, without the need to manually reconstruct the acquired data and then import it into the software for the design of orthopedic insoles;

[0070] 3. The technical solution of the present invention does not involve data circulation and repeated verification. All test and design data flow in one direction. The operation is simple and convenient for ordinary medical workers to participate in and implement.

[0071] 4. The technical solution of the present invention considers the feasibility of manufacturing the orthopedic insole during the design stage, and can perform diagnosis while collecting data; and after the design of the insole is completed, the expected orthopedic effect can be achieved without the need for a verification step.

[0079] The present invention will be further described below in conjunction with the accompanying drawings.

[0080] The technical solution of the present invention is aimed at the entire production workflow of orthopedic insoles.

[0081] The production of orthopedic insoles described therein is divided into three major stages: data collection, design, and manufacturing; the three steps can be completed, or a step can be stopped at any time to achieve different effects (for example, only data collection can diagnose the cause of the disease, and when it comes to the design stage, it can be used to predict the expected recovery effect of the corresponding disease, etc.).

[0082] First of all, it should be noted that orthopedic insoles are not only a treatment for foot diseases such as diabetic foot, flat feet, metatarsal pain, heel pain, plantar fasciitis, etc., but can also be helpful for problems in the knee joint, hip joint, waist and other parts of the body (the foot is the foundation and the others are the superstructure).

[0083] Specifically, Figure 1 As shown in, the technical solution of the present invention comprises the following steps:

[0084] A. Data Collection:

[0085] A1. Collection:

[0086] Conventional bio-information collection includes: static plantar contour, plantar pressure, and force line.

[0087] With the help of the "liftable matrix foot testing equipment", dynamic / static data can be obtained, and the soft tissue characteristics of the foot such as elastic modulus (displacement and force) and bone movement (after touching the bone position on the body surface, a marker point is attached, and the movement trajectory of the marker point will be recorded in real time);

[0088] A2. Processing data:

[0089] In the prior art, the collected data of the above three conventional biological information are in an isolated state and are only used as diagnostic indicators for doctors to manually judge;

[0090] The "Lifting Matrix Foot Test Device" is used to collect data from normal people and patients with different foot diseases. After grouping, it is trained through artificial intelligence to enable it to have diagnostic capabilities, as follows:

[0091] A2.1. Experts diagnose and confirm normal people and patients, register basic information such as age, gender, BMI (Body Mass Index) and the above-mentioned biological information, group the data according to age, gender, BMI, condition, etc., and train the large model Ai.

[0092] A2.2. After the AI ​​training is completed, after registering the basic information of the test-taker and collecting multiple biological information, a diagnosis can be made: whether the patient is ill and what disease the patient has.

[0093] That is, diagnosis is performed while data is being collected.

[0094] B. Design:

[0095] Conventional design can be divided into several different levels: 1) Design based on partial data, mostly the contour of the sole of the foot; 2) Design based on multiple data, but multiple data interfere with each other and are not integrated well (left and right hands compete with each other); 3) Integrate multiple data but the effect can only be verified after manufacturing and wearing; 4) Before manufacturing, iterate and verify the effect through some means, which takes a lot of time (similar to guessing numbers). All of the above require importing data into design software for design.

[0096] B1) Correction:

[0097] Then, the AI ​​mentioned in the data collection can not only diagnose the condition, but also autonomously correct the foot problem temporarily (essentially, the manufactured insole continues the corrected state, allowing it to be corrected permanently)

[0098] Take flat feet, one of the foot diseases, as an example: after a patient is diagnosed with flat feet, the device analyzes the patient's basic information (age, gender, BMI, etc.) and biometric information, finds the normal arch height that matches the patient's characteristics, and raises the matrix to restore the arch.

[0099] B2) Insole contour:

[0100] The final height of each matrix after lifting represents the center of its area, thus generating the outline of the insole;

[0101] B3) Softness and hardness design:

[0102] If the material density is consistent, "the thicker the material, the harder it is", but this is not what we want.

[0103] The lifting matrix has displacement and collected force during the lifting process, which means that the appropriate softness and hardness, that is, the appropriate material density, at different positions of the insole can be known.

[0104] Because CNC and conventional 3D printing technologies have the same material density, it is necessary to use the method in “Orthopedic Insole Preparation Method” to further generate the design.

[0105] At this point, the insole design is complete and no verification is required in principle.

[0106] C. Manufacturing:

[0107] More emphasis is placed on design, and manufacturing can highlight the uploading of designs to the cloud and automatic issuance of printing and manufacturing.

[0108] Specifically, Figures 2 to 5 As shown in , the aforementioned lifting matrix foot testing device includes a base 1, an electric push rod 2, a camera 4, a laser locator 5 and a control host 6;

[0109] The base is a groove-shaped structure with side walls, used to accommodate a single foot of the person being tested;

[0110] In the groove-shaped structure, a group of electric push rod matrices composed of a plurality of electric push rods is arranged;

[0111] Each of the plurality of electric push rods is provided with a displacement sensor 8 for measuring and providing the lifting height or lifting stroke of the push rod of the electric push rod;

[0112] A force sensor 7 is provided below each electric push rod to measure the pressure on the sole of the foot borne by each electric push rod;

[0113] A camera 4 is installed on the left and right sides of the base groove respectively, for capturing the image of the foot of the test subject in real time and transmitting the image to the control host;

[0114] At the rear of the base, a laser locator 5 is provided for emitting a green line laser beam vertically and horizontally to the ground to the Achilles tendon of the foot of the person being tested;

[0115] The control host 6 is used to control the lifting height of each electric push rod and obtain the pressure feedback data of each push rod in real time;

[0116] At the same time, the control host calculates the inversion and valgus angles of the left or right foot based on the relative angle relationship between the laser beam and the Achilles tendon;

[0117] The control host is internally integrated with an FGPA control unit, which processes the feedback data of each electric linear actuator in the electric linear actuator matrix and transmits it to the control host through row and column scanning and signal processing circuits;

[0118] The software system in the control host controls the longitudinal displacement of each push rod in real time by detecting the output data of each displacement sensor, so as to control the shape of the sole of the tested person, and accurately displays the force condition of the sole under the shape by reading the data of the stress sensor;

[0119] The foot testing device based on the lifting matrix realizes the pushing of different parts of the sole of the testee's foot by controlling the pushing force applied to each electric push rod; measures the pressure data of the corresponding points on the sole of the testee's foot by controlling the different lifting heights of each electric push rod; compares the measured foot shape and pressure data of each point on the sole with the standard or conventional normal foot shape and sole pressure data, so as to obtain the lifting height required for different parts of each foot of the testee and the pressure they need to withstand; and then formulates a personalized correction plan of "private customization" nature for individual testees of different ages and different symptoms to ensure the consistency of the foot shape and sole pressure of the testee.

[0120] For further description of the above-mentioned foot testing device based on the lifting matrix, please refer to the other contents in the invention patent application "A foot testing device based on the lifting matrix" applied by the applicant on the same day, which will not be described here.

[0121] Specifically, Figure 6 As shown in the above, the aforementioned "method for preparing orthopedic insoles" mainly comprises the following steps:

[0122] 1) Data collection:

[0123] 1.1) Collecting plantar contour information and plantar pressure information;

[0124] 2) Design:

[0125] 2.1) Prepare the insole shape using the plantar contour information;

[0126] 2.2) Project the sole pressure onto the insole;

[0127] 2.3) Divide the insole into different areas according to different plantar pressure distribution;

[0128] 2.4) Performing lattice processing;

[0129] 2.5) Provide smooth transition between different areas;

[0130] 3) Manufacturing:

[0131] 3.1) 3D printing machine selection;

[0132] 3.2) Convert the insole after gentle transition into a file recognizable by a 3D printer;

[0133] 3.2) Use 3D printing to obtain orthopedic insoles with a smooth transition of softness and hardness between different areas.

[0134] The technical solution of the above-mentioned "method for preparing orthopedic insoles" arbitrarily divides the insole into different areas according to the plantar pressure distribution; it can conveniently adjust the stiffness of different partition positions; obtain the effect of smooth transition of softness and hardness between different areas; and thus achieve the purpose of smooth transition between different areas, which is helpful to manufacture orthopedic insoles that meet the user's customized needs, have different softness and hardness at different positions, and have a smooth transition between different softness and hardness, and are comfortable to wear.

[0135] For further description of the “method for preparing orthopedic insoles”, please refer to the other contents in the invention patent application “method for preparing orthopedic insoles” filed by the applicant on the same day, which will not be described here.

[0136] Example:

[0137] After the patient steps on the foot testing device and is diagnosed with flat feet, the device automatically lifts the electric push rod (electric cylinder for short) in the arch area and slightly lowers the electric cylinders at the forefoot and heel positions to generate the insole contour and real-time plantar pressure.

[0138] Based on the thickness of the insole at different positions and the pressure distribution at that position, the stiffness of the insole at that position is calculated, and the insole design is generated based on the stiffness. Then the insole is printed and manufactured based on this design.

[0139] The technical solution of the present invention collects data accurately and integrates diagnosis and treatment plans. The design is more scientific and can be designed by the user after diagnosis. From collection, design, to manufacturing, data flow is all on the computer side without manual participation, reducing the situation where design and manufacturing do not meet requirements due to data distortion.

[0140] The invention can be widely used in the design and preparation fields of orthopedic insoles.
