Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a 3D printing customized preparation method for ankle instability in sports people and a corrector thereof. Background Art

[0002] In the field of sports, ankle instability is a common sports injury, especially in high-intensity or high-frequency change of direction sports such as running, basketball, and football. Ankle instability not only affects the individual's sports performance, but may also lead to serious sports injuries such as sprains, ligament tears, and even fractures.

[0003] Traditional orthotics usually adopt standard sizes and shapes, which are difficult to meet the specific needs of different individuals. Since everyone's ankle morphology, muscle strength and exercise habits are different, standardized orthotics often cannot provide the best support and stability. In addition, the manufacturing process of traditional orthotics usually involves hand-made or mold forming, which makes it difficult to ensure the accuracy and quality of the product.

[0004] In summary, the development of an ankle instability corrector for athletes based on 3D printing technology requires comprehensive consideration of data collection, personalized design, material selection, 3D printing manufacturing, post-processing and adaptation, etc. By continuously optimizing and improving these technical links, a corrector with high personalization, high-precision manufacturing and excellent performance can be developed to provide athletes with a safer, more comfortable and more effective correction solution. Summary of the invention

[0005] In order to solve the problems of the prior art, the present invention provides a 3D printing customized preparation method for ankle instability in sports people and a corrector thereof.

[0006] In order to solve the above technical problems, the present invention is implemented by the following technical solutions: In the first aspect, a 3D printing customized preparation method for ankle instability in sports people and a corrector thereof, comprising the following steps:

[0007] Step 1: Data collection: Collect the individual's calf thickness, ankle eversion / inversion angle, heel shape, and plantar pressure distribution parameters;

[0008] Step 2: Data analysis and design: Input the collected data into computer-aided design software for 3D modeling and design of an orthosis model that meets the characteristics of the individual ankle joint. The model range covers the sole of the foot to 5 cm above the ankle joint.

[0009] Step 3: 3D printing manufacturing: Use high-precision 3D printing equipment to print and manufacture according to the designed orthosis model. The material should be lightweight, high-strength, wear-resistant and breathable special materials;

[0010] Step 4: Post-processing and fitting: Perform necessary post-processing on the printed orthosis, including polishing and disinfection, and make fine adjustments based on trial feedback to ensure that the orthosis fits the individual ankle joint perfectly.

[0011] In this aspect, through precise data collection, personalized design and manufacturing, it is intended to provide a corrector that fits perfectly with the individual ankle joint, thereby effectively supporting and stabilizing the ankle joint and reducing the risk of sprains during exercise.

[0012] Traditional orthotics often adopt a "one-size-fits-all" design, which is difficult to meet the specific needs of different individuals. However, this method can design an orthosis that fully meets the characteristics of individual ankle joints through data collection and 3D modeling, achieving true personalized customization;

[0013] The use of high-precision 3D printing technology can ensure the manufacturing accuracy and quality of the corrector and avoid the errors that may occur in traditional manual production;

[0014] The selection of special materials that are lightweight, high-strength, wear-resistant and breathable not only improves the performance of the corrector, but also ensures the comfort and safety of wearing;

[0015] Through necessary post-processing and trial-feedback fine-tuning, it is possible to ensure that the orthosis fits the individual ankle joint perfectly, further improving its stability and orthotic effect.

[0016] In a specific implementation of the first aspect, data collection specifically includes:

[0017] Use high-precision 3D scanning equipment to perform a full-scale scan of the individual's ankle joint and calf to obtain detailed three-dimensional morphological data, including but not limited to the thickness of the calf, the eversion / inversion angle of the ankle joint, the shape of the heel, the curvature of the sole, and possible pathological characteristics;

[0018] With the help of the plantar pressure distribution measurement system, the pressure distribution data of the plantar of the individual during static standing and dynamic walking is recorded to evaluate the force status of the ankle joint and potential instability factors;

[0019] If necessary, manual measurement tools are used to collect additional dimensional data of specific parts, including ankle circumference and arch height, to ensure the completeness and accuracy of the data;

[0020] In a specific embodiment of the first aspect, the special material is a high-performance polymer or composite material, which has sufficient strength and toughness to meet the support and stability requirements during exercise while maintaining good breathability and comfort.

[0021] Secondly, the corrector has a personalized shape and size that perfectly fits the individual's ankle joint morphology, can effectively support and stabilize the ankle joint, and reduce the risk of sprains during exercise.

[0022] In the second aspect, through personalized shape and size design, as well as optimization of plantar pressure distribution, the corrector can not only effectively reduce the risk of sprains during exercise, but also improve wearing comfort and orthotic effect.

[0023] The personalized shape and size of the orthosis can perfectly fit the individual's ankle morphology, avoiding the pressure or discomfort that traditional orthosis may cause due to inappropriate size;

[0024] By adjusting the shape and material distribution of the orthosis, the force on the sole of the foot can be optimized, reducing the risk of fatigue and injury caused by uneven force. This feature is particularly important in sports and can significantly improve individual sports performance and comfort;

[0025] The personalized orthotic design can more effectively support and stabilize the ankle joint and reduce the risk of sprains during exercise. This is an important protective measure for people who frequently engage in high-intensity or high-risk sports.

[0026] Through precise data collection and design, the orthosis can provide targeted orthopedic treatment based on the individual's ankle joint characteristics, thereby improving the orthotic effect and accelerating the recovery process.

[0027] In a specific implementation of the second aspect, the design of the orthosis also takes into account the plantar pressure distribution, and optimizes the plantar force by adjusting the shape and material distribution of the orthosis, thereby further improving the wearing comfort and orthotic effect.

[0028] The beneficial effects of the present invention are:

[0029] 1. The present invention can accurately capture key data such as individual ankle joint morphology, eversion / inversion angle, heel morphology, and plantar pressure distribution through high-precision 3D scanning and plantar pressure distribution measurement. Based on these data, computer-aided design software can generate an orthotic model that fully meets individual characteristics to ensure that the orthotic fits the individual ankle perfectly. This highly personalized customization solution can provide more precise support and stabilization effects, effectively reducing the risk of sprains during exercise;

[0030] 2. The design of the corrector fully considers the pressure distribution on the sole of the foot, and optimizes the force by adjusting the shape and material distribution. This helps to reduce the risk of fatigue and injury caused by uneven force, and improves sports performance and comfort. Especially for individuals with pathological characteristics (such as flat feet, high arches, etc.), optimizing the force distribution can significantly improve their sports experience and health;

[0031] 3. The use of high-precision 3D printing technology to manufacture correctors can ensure the accuracy and quality of the product. The selection of special materials that are lightweight, high-strength, wear-resistant and breathable can meet the support and stability requirements during exercise while maintaining good breathability and comfort. This material selection and optimization not only improves the performance of the corrector, but also extends its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Example: Preparation and application of 3D printed customized corrector for ankle instability in sports people

[0046] Data collection phase

[0047] High-precision 3D scanning:

[0048] Use high-precision 3D scanning equipment (such as a laser scanner or structured light scanner) to perform a full-scale scan of the individual's ankle and lower leg.

[0049] During the scanning process, ensure that the individual is in a natural standing position to obtain the most realistic three-dimensional morphological data.

[0050] The scan results include the thickness of the calf, the eversion / inversion angle of the ankle joint, the shape of the heel, the curvature of the plantar foot, and possible pathological characteristics (such as flat feet, high arches, etc.).

[0051] Plantar pressure distribution measurement:

[0052] With the help of a plantar pressure distribution measurement system (such as a pressure sensing insole or a pressure distribution plate), the pressure distribution data of the plantar of an individual is recorded during static standing and dynamic walking.

[0053] Static standing measurement is used to evaluate static force conditions, while dynamic walking measurement is used to evaluate force changes during movement.

[0054] By analyzing the pressure distribution data, the points of unbalanced force and potential instability in the ankle joint can be identified.

[0055] Manual measurement supplement:

[0056] Use manual measuring tools (such as tape measures, vernier calipers, etc.) to supplement the collection of dimensional data of specific parts, including ankle circumference, arch height, etc.

[0057] These data are used to further verify and optimize the results of 3D scanning and plantar pressure distribution measurement to ensure the integrity and accuracy of the data.

[0058] Data analysis and design phase

[0059] Data input and 3D modeling:

[0060] Input the collected data into computer-aided design software (such as SolidWorks, Autodesk Inventor, etc.).

[0061] Based on the data, 3D modeling is performed to design an orthosis model that meets the characteristics of the individual ankle joint. The model range covers the sole of the foot to 5 cm above the ankle joint to ensure adequate support and stability.

[0062] Personalized design optimization:

[0063] According to the plantar pressure distribution data, the shape and material distribution of the orthosis are adjusted to optimize the plantar force.

[0064] By adjusting the thickness, curvature and material distribution of the orthosis, the risk of fatigue and injury caused by uneven force can be reduced.

[0065] 3D printing manufacturing stage

[0066] Material selection:

[0067] Choose high-performance polymers or composite materials that are lightweight, high-strength, wear-resistant and breathable as printing materials.

[0068] These materials have sufficient strength and toughness to meet the support and stability needs during exercise, while maintaining good breathability and comfort.

[0069] 3D Printing Manufacturing:

[0070] Use high-precision 3D printing equipment (such as SLA, SLS or FDM, etc.) to print and manufacture the orthosis according to the designed model.

[0071] During the printing process, ensure printing accuracy and layer thickness control to obtain high-quality orthotic products.

[0072] Post-processing and adaptation stage

[0073] Post-processing:

[0074] The printed orthosis is subjected to necessary post-processing, including grinding to remove burrs and disinfection to kill bacteria.

[0075] These treatment steps are designed to improve the comfort and security of the orthosis.

[0076] Adaptation and fine-tuning:

[0077] Fine-tune the orthosis based on fitting feedback to ensure it fits the individual ankle perfectly.

[0078] If necessary, the shape, size or material distribution of the orthosis can be fine-tuned to further improve wearing comfort and the orthotic effect.

[0079] Specific advantages

[0080] Highly Personalized:

[0081] The orthosis is tailored to the individual's ankle morphology, providing more precise support and stabilization.

[0082] Compared with traditional orthotics, personalized custom orthotics can significantly reduce the risk of sprains during sports.

[0083] Optimizing plantar force:

[0084] By adjusting the shape and material distribution of the orthosis, the force on the sole of the foot is optimized and the risk of fatigue and injury caused by uneven force is reduced.

[0085] This helps improve individual performance and comfort.

[0086] High-precision manufacturing:

[0087] The orthotic devices are manufactured using high-precision 3D printing technology to ensure the quality and accuracy of the products.

[0088] This helps ensure stability and durability of the aligners, extending their lifespan.

[0089] Material optimization:

[0090] Lightweight, high-strength, wear-resistant and breathable materials are selected as printing materials to meet the support and stability requirements during exercise.

[0091] At the same time, these materials have good breathability and comfort, which helps to improve the wearing experience.

[0092] In summary, the 3D printed customized corrector for ankle instability in athletes has significant advantages such as high personalization, optimized plantar force, high-precision manufacturing and material optimization, and can provide athletes with safer, more comfortable and more effective correction solutions.

[0093] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
