Description

TECHNICAL FIELD

[0001] The present application relates to the field of foot orthotic technology, in particular to a novel foot orthotic device and method. BACKGROUND

[0002] Foot orthotic aids are important medical auxiliary equipment for improving lower extremity biomechanical abnormalities and related foot mechanical problems. Among them, orthotic insoles, as the core category, can adapt to the individual foot shape by changing the ground support form, thereby providing correction and pain relief support for lower extremity biomechanical abnormal groups, such as flat feet, hallux valgus, and ankle instability patients.

[0003] In practical application, traditional orthotic insoles have many basic functions: they can correct lower extremity weight lines, adjust abnormal stress on bones and joints, improve foot valgus and imbalance of ankle and knee joint stress, reduce chronic damage to alleviate or eliminate symptoms such as back pain and waist pain; prevent the occurrence of flat foot complications, correct abnormal gait and restore normal arch, provide scientific arch support, relieve foot fatigue, pain and calf muscle soreness; they can also relieve tension and strain of the plantar fascia, relieve foot pressure to relieve pain, and long-term wear can relieve or eliminate related symptoms; at the same time, they can redistribute the stress on the foot, and long-term use can eliminate calluses on the foot; in addition, they have a preventive effect on hallux valgus and hallux capsulitis, and can balance the muscle and ligament strength on both sides of the ankle joint, correct the inclination of the ankle joint surface, enhance stability, thereby relieving chronic pain after habitual ankle sprain and reducing the risk of re-injury.

[0004] However, the current traditional orthotic insoles have significant defects in technical application and actual service, and cannot meet the needs of users for individualization, efficiency and comfort: first, the individualization customization ability is insufficient, and most of them are fixed shape, which is difficult to effectively adapt to individual differences, and the technical service system is also difficult to provide precise customization on a large scale in the short term; second, the supply chain efficiency is low, the manufacturing relies on the combination of machinery and manual work, the communication between users, doctors and manufacturers is complicated, and the insoles need to be adjusted several times before delivery, which prolongs the cycle and affects the use experience; third, the comfort and adaptability are not good, the fixed shape insole is easy to wear and deform after long-term use, which not only reduces the correction effect, but also may cause foot discomfort; fourth, the technical application has limitations, although digital and 3D printing technologies have made progress, the popularization of orthotic insoles in this field faces challenges such as insufficient technical maturity, difficult cost control, and long customization adjustment period, which cannot be widely used in mass production and individualization customization.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] This invention discloses a novel rapid orthopedic device for the sole of the foot.

[0032] Reference Figures 1-3 A novel rapid orthotic device for the sole of the foot includes a locator 1 and a rapid orthotic insole 2. The two are positioned and adjusted through a detachable mating structure, which not only ensures assembly stability but also flexibly adapts to the foot shape of different users, providing a foundation for subsequent personalized orthotics.

[0033] The rapid orthotic insole 2 includes a surface layer 21 and a partitioned substrate 22, which are integrally and fixedly connected, such as by heat-pressing or bonding. This design avoids delamination during use, ensuring structural stability and ensuring that the force on the sole of the foot can be accurately transmitted to the partitioned substrate 22 through the surface layer 21 without force transmission loss, thus improving the orthotic effect. The bottom surface of the partitioned substrate 22, away from the surface layer 21, has several transverse grooves 24, which divide the bottom of the partitioned substrate 22 into several adjustable positioning blocks 23. The width of the transverse grooves 24 in the rapid orthotic insole 2 is 0.2-5mm, preferably 0.5-3mm, which ensures that the positioning blocks 23 have sufficient elastic adjustment space while also maintaining support stability, ensuring that the positioning blocks 23 can flexibly adapt to the shape of the foot while avoiding the risk of breakage.

[0034] The positioner 1 has several transverse straight grooves 11 evenly distributed along its transverse direction. The groove width of the transverse straight grooves 11 is uniform, and the spacing between adjacent transverse straight grooves 11 is consistent. The groove width of the transverse straight grooves 11 on the positioner 1 is 2-30mm, preferably 3-15mm. The positioning block 23 corresponds to the transverse straight groove 11, and the positioning block 23 can be inserted into the corresponding transverse straight groove 11 with a transitional fit between the two. The partition base 22 is made of an elastic material. This design allows the elastic material to deform slightly under stress, facilitating the movement of the positioning block 23 along the transverse groove 11 of the locator 1 with minimal force after insertion, thus improving adjustment convenience. Furthermore, when the support block conforms to the sole of the foot, it can adaptively adjust its shape according to foot pressure, reducing localized pressure and balancing orthotic effect with wearing comfort. When the locator 1 is assembled with the quick-correcting insole 2, the positioning block 23 is inserted into the transverse groove 11 of the locator 1, and applying a certain force pushes the quick-correcting insole 2 to move along the transverse groove 11 of the locator 1 to adapt to different foot shapes.

[0035] The surface layer 21 is made of any one of the following materials: woven fabric, EVA, oxysol, hyperpoly, silicone, soft rubber, or foam; the partition base 22 is made of any one of the following materials: EVA, oxysol, hyperpoly, silicone, soft rubber, or foam. If the surface layer 21 is made of woven fabric, its advantage lies in its good breathability and moisture absorption, which can reduce the stuffiness of the feet during long-term wear and improve comfort. If the surface layer 21 and the partition base 22 are made of the same material, it can ensure the consistency of the materials, reduce interlayer friction wear, and extend the service life of the insole. At the same time, these materials all have excellent elasticity and abrasion resistance, and are not easily deformed after long-term use, which can stably maintain the orthopedic effect and avoid the decrease in orthopedic accuracy due to material deformation.

[0036] The partitioned substrate 22, away from the surface layer 21, has several longitudinal grooves 25 along its bottom surface. These grooves intersect with the transverse grooves 24 to form a grid structure, dividing the partitioned substrate 22 of the quick-correcting insole 2 into several independently adjustable support blocks. These independently adjustable support blocks can be adapted to the different contours of different areas of the foot, such as the forefoot, arch, and heel. For example, the arch area requires higher support, while the forefoot area needs to distribute pressure. By individually adjusting the height and position of the corresponding support block, a precise fit is achieved, avoiding the problem of insufficient localized fit caused by the one-size-fits-all approach of traditional fixed insoles.

[0037] Reference Figure 5 In another embodiment, the bottom surface of the partitioned substrate 22 away from the surface layer 21 is provided with a number of longitudinal curved grooves 26. The longitudinal curved grooves 26 intersect with the transverse grooves 24 to form a grid structure, dividing the partitioned substrate 22 of the quick orthotic insole 2 into a number of irregularly shaped support blocks. This design is mainly for complex foot contours, such as mild hallux valgus, asymmetrical arch, heel deformity, etc. The curved grooves can divide the irregular shape of the foot anatomy structure into irregular support blocks that match the key force areas of the foot, so as to achieve precise point-to-point support, expand the range of people to whom the device is applicable, and are especially suitable for the orthotic needs of non-standard foot shapes.

[0038] Reference Figure 4In order to improve the adaptability to different foot sizes, in some embodiments, the surface layer 21 of the quick orthotic insole 2 is provided with several shoe size cutting lines 27 to meet the usage needs of different people.

[0039] To improve the support stability of the quick orthotic insole 2, in some embodiments, the quick orthotic device for the foot also includes several inserts. These inserts are inserted into the transverse groove 24 and longitudinal groove 25 of the quick orthotic insole 2 after it has been cut, thereby improving the support strength of the quick orthotic insole 2 during actual use and making it less prone to large compression deformation during long-term use, thus ensuring the orthotic effect.

[0040] The present invention also discloses an orthopedic method based on the above-mentioned novel rapid plantar orthopedic device, comprising the following steps: S1: Foot morphology detection: Using foot morphology detection tools, detect and determine the state of foot deformities; Reference Figures 6-8 The foot morphology detection tool includes a reference silicone pad 31 and a laser pointer 32. The upper surface of the reference silicone pad 31 is drawn with a footprint reference line 313 and several vertically intersecting horizontal and vertical markings 311 and 312. The spacing between the horizontal markings 311 and the spacing between the vertical markings 312 are 5-10 mm; in this embodiment, 10 mm is used. The laser pointer 32 has a cross-shaped slot at its emission port, allowing it to emit a cross-shaped laser line.

[0041] The user stands barefoot, marks the heel line on the skin, presses the foot onto the reference silicone pad 31, and ensures that the tip of the second toe closest to the big toe is aligned with one of the longitudinal lines of the reference silicone pad 31, while the edge of the foot is as close as possible to the outer contour of the standard footprint reference line 313. Then, laser pointer 32 is used to illuminate the heel, with the axis of laser pointer 32 perpendicular to the surface of the reference silicone pad 31. The horizontal line of the cross-shaped laser emitted by laser pointer 32 coincides with the horizontal marking 311 of the adjacent heel. At this time, one end of the vertical line of the cross-shaped laser is projected onto the heel and compared with the foot's force line. If the heel force line deviates outward from the longitudinal laser line, forming an angled deviation, it is determined to be inversion deformity; if the heel force line deviates inward from the longitudinal laser line, forming an angled deviation, it is determined to be eversion deformity. The size of the deformity angle can be accurately measured by taking a picture directly at the heel. S2: Assembly and positioning: Align the positioning block 23 of the quick orthotic insole 2 that matches the shoe size with the transverse straight groove 11 of the locator 1, so that the positioning block 23 is inserted into the corresponding transverse straight groove 11, and the initial assembly of the two is completed. S3: Positioner 1 fixation: Suspend the assembled positioner 1 flat or hold it in your hand to ensure that the bottom surface of the partition base 22 of the quick orthopedic insole 2 is fully exposed and not obstructed. S4: Force Line Correction: Have the user sit with both knees and ankles at 90 degrees. Gently place the sole of the foot on the surface 21 of the quick orthotic insole 2 and adjust the foot position to correct the lower limb weight-bearing force line. Abnormal lower limb weight-bearing force lines, such as force line deviation caused by foot eversion or force imbalance caused by foot inversion, are the core causes of foot pain and joint damage. This step adjusts the foot posture to bring the lower limb force line back to the normal physiological trajectory. For example, adjusting the everted foot to a neutral force line position provides the correct reference direction for subsequent support adaptation. If the force line is not corrected before adaptation, the support direction will deviate from the normal force line, which will not only fail to achieve the orthotic effect but may also cause foot discomfort. Therefore, this step is a prerequisite for ensuring the effectiveness of the orthosis.

[0042] S5: Support Adaptation: Maintaining the neutral force line position described above, push and pull the quick-correcting insole 2 along the transverse groove 11 of the locator 1, and push the support block of the partition base 22 upwards, so that the support block fits snugly against the arch area, heel periphery area, and forefoot area of ​​the user's foot, forming a personalized support shape; after the support block fits against the sole of the foot, it is necessary to ensure that the support height in the arch area is not lower than the lowest point of the user's arch by 1-3mm, which can ensure that the force on the heel is evenly distributed, avoiding local pressure concentration, and not reducing the flexibility of adjustment due to full coverage, thus balancing support stability and comfort; the support coverage rate in the heel periphery area is not less than 80% of the heel area. In addition, for those with calluses on their feet, or local or regional pain, the height of the support block should be adjusted appropriately to reduce pressure and relieve pain.

[0043] S6: Cutting and shaping: Use a thin blade cutter to cut the partition base 22 along the upper surface of the locator 1, and cut and separate the adapted quick orthotic insole 2 from the locator 1; and the blade thickness of the thin blade cutter does not exceed 0.5mm, and the blade is kept parallel to the upper surface of the locator 1 during cutting.

[0044] S7: Re-inspection of Corrective Effect: The cut quick-correcting insole 2 is placed inside the mold cavity 42 of the re-inspection mold 4. The re-inspection mold 4 is made of plastic, its shape is similar to the sole of a shoe, and like the shoe, it has different sizes to fit different people. The re-inspection mold 4 has a mold cavity 42 inside and a mold upper 41 outside. The quick-correcting insole 2 is located inside the mold cavity 42. The re-inspection mold 4 provides support and restraint for the quick-correcting insole, simulating the user's state of wearing shoes, to ensure the actual effectiveness of the correction. Afterwards, the user steps on the quick-correcting insole 2 and stands up, and the force line is checked again using a foot shape detection tool to verify the corrective effect.

[0045] S8: Orthotic Use: Place the re-inspected and confirmed quick-correcting insole 2 into the user's shoe, ensuring that the insole surface 21 conforms to the sole of the foot, achieving foot orthotics. The surface 21 directly contacts the sole of the foot, and its excellent fit ensures that the support force of the partitioned base 22 is accurately transmitted to key areas of the sole. Through continuous support, it corrects abnormal stress on the sole, gradually improves the biomechanical balance of the lower limbs, and relieves pain caused by abnormal foot shape. It is especially helpful for adolescents to correct the biomechanical alignment of the lower limbs and improve motor function. At the same time, long-term wear maintains the orthotics effect, avoiding further aggravation of joint damage by abnormal stress, achieving the dual goals of comfortable wear and precise orthotics.

[0046] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
