Description

Technical Field

[0001] This utility model relates to orthopedic tools, and more specifically, to an orthopedic insole. Background Technology

[0002] Human posture is closely related to human health. Incorrect posture can cause an imbalance between antagonistic and agonist muscles, resulting in deviations in the three axes of front-back, left-right, and up-down, and causing imbalances in other parts of the body, and may even affect the skeleton.

[0003] Taking foot eversion as an example, foot eversion is caused by contracture of the peroneal muscles, resulting in an everted foot position, with the calcaneus shifting outward, the talus subluxating inward, and the inner edge of the arch lowered. The harms and effects of foot eversion include increased risk of foot injury, knee pain, and impaired foot function. Specifically: 1. Increased risk of foot injury: Foot eversion leads to uneven pressure on the foot, making it susceptible to sprains, deformities, fractures, and other injuries. 2. Knee pain: Foot eversion causes the force of the foot to be transmitted inward, resulting in excessive pressure on the medial aspect of the knee joint, thus causing knee pain and inflammation. 3. Impaired foot function: Foot eversion affects the normal support and balance function of the foot, making activities such as walking and running difficult.

[0004] Correction of pronation includes massage, exercise, and surgery. Orthotic insoles can serve as an adjunct tool to alleviate and treat pronation symptoms. However, existing orthotic insoles are difficult to modify to fit the specific foot characteristics of each patient. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing orthotic insoles, which are difficult to add or remove and adapt to the characteristics of patients' feet. It provides an orthotic insole that can better adjust the shape of the insole, thereby more easily adapting to the shape of the patient's foot, and specifically strengthening it for their condition, thus improving the treatment effect.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An orthotic insole includes an insole body and a flexible additive. The insole body has additive holes, and the flexible additive fills the additive holes. The additive holes are located at one or more positions of the insole corresponding to the metatarsophalangeal joint, arch, and heel. The additive holes and the flexible additive are configured according to the shape of the orthotic foot. The flexible additive is made of silicone, and the hardness of the silicone ranges from 0 to 40 degrees.

[0008] Flexible additive manufacturing, as the name suggests, involves adding material into additive holes for curing, resulting in a flexible cured product. This application reduces the need for drilling by pre-setting additive holes; the height of the flexible additive can be adjusted simply by changing the amount of material, thus adapting to different symptoms of clubfoot.

[0009] This application uses the insole body as a base, providing corresponding additive holes to support flexible additives. For areas where high elasticity is not required, high-rigidity flexible additives are used, while for areas requiring high elasticity, low-rigidity flexible additives are used. Through adaptive adjustments, the feel and therapeutic effect of the orthopedic insole are improved.

[0010] Medical staff using this application do not need to spend time drilling and controlling the drilling depth; they only need to drip liquid silicone and wait for it to set to complete the preparation of the orthopedic insole.

[0011] Preferably, the hardness of the flexible additive filling the additive hole is adapted to the filling position.

[0012] Preferably, the additive holes corresponding to the metatarsophalangeal joint are filled with several layers of flexible additives. From the inside out, the hardness of the flexible additives gradually decreases, thereby obtaining a soft-then-hard feel and achieving good support.

[0013] Preferably, the depth of the additive hole corresponding to the metatarsophalangeal joint is between 1 and 5 mm.

[0014] Preferably, the shape of the additive hole corresponding to the metatarsophalangeal joint is formed by five parallel circular portions stacked on top of each other, the circles corresponding to each metatarsal head, wherein the diameter of the circle corresponding to the first metatarsal head is larger than the other circles.

[0015] Preferably, the width of the additive hole corresponding to the arch position is the same as the width of the insole body, and this structure can fully cover the plantar fascia.

[0016] Preferably, the flexible additive on the additive hole corresponding to the arch position is higher on the inner side of the foot than on the outer side, so as to conform to the shape of the arch.

[0017] Preferably, the additive hole corresponding to the heel is teardrop-shaped, with one end larger than the other, and the tail of the teardrop pointing towards the front of the insole body.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) By setting up additive holes and using silicone as a flexible additive, medical staff can easily customize orthotic insoles according to the patient's foot shape.

[0020] (2) Additive holes at the metatarsophalangeal joint, arch and dorsum of the foot can cover the vast majority of foot eversion symptoms. Attached Figure Description

[0029] Example:

[0030] A type of orthopedic insole, Figure 1 As shown, the insole includes an insole body 1 and a flexible additive 2. The insole body 1 is provided with additive holes 3, and the flexible additive 2 fills the additive holes 3. The additive holes 3 are located at one or more positions of the insole corresponding to the metatarsophalangeal joint, arch, and heel. The additive holes 3 and the flexible additive 2 are set according to the shape of the orthopedic object's foot. The flexible additive 2 is made of silicone, and the hardness of the silicone ranges from 0 to 40 degrees.

[0031] The additive holes 31 corresponding to the metatarsophalangeal joints are filled with several layers of flexible additive 2. From the inside out, the hardness of the flexible additive 2 gradually decreases, thus achieving a soft-to-firm feel and providing good support. The depth of the additive holes 31 corresponding to the metatarsophalangeal joints is between 1 and 5 mm. The shape of the additive holes 31 corresponding to the metatarsophalangeal joints is formed by five parallel circular portions stacked on top of each other. The circles correspond to the metatarsal heads, wherein the diameter of the circle corresponding to the first metatarsal head is larger than that of the other circles.

[0032] The width of the additive hole 32 corresponding to the arch position is the same as the width of the insole body 1, and this structure can fully cover the plantar fascia. The flexible additive 2 on the additive hole 32 corresponding to the arch position is higher on the inner side of the corresponding foot than on the outer side, thus conforming to the shape of the arch.

[0033] The additive hole 33 corresponding to the heel is teardrop-shaped, with one end larger than the other, and the tail of the teardrop points towards the front of the insole body 1.

[0034] The hardness of the flexible additive 2 filling the additive cavity 3 is adapted to the filling position. (See reference...) Figure 2 As shown, specifically, the flexible additive 2 at the metatarsophalangeal joint and arch gradually softens from the inside out, and its perforation depth is 2-3 mm in some preferred embodiments. The stiffness of the flexible additive 2 at the heel is preferably 25-35 degrees.

[0035] As the name suggests, the flexible additive 2 is an additive that can be added into the additive holes 3 and cured, resulting in a flexible product. This application reduces the need for drilling by pre-setting the additive holes 3. By simply adjusting the amount of flexible additive 2, its height can be adjusted to accommodate different symptoms of clubfoot.

[0036] This application uses the insole body 1 as a base, and provides corresponding additive holes 3 on it to support the flexible additive 2. For areas where high elasticity is not required, a high-hardness flexible additive 2 is used, while for areas where high elasticity is required, a low-hardness flexible additive 2 is used. Through adaptive adjustments, the feel and therapeutic effect of the orthopedic insole are improved.

[0037] Medical staff using this application do not need to spend time drilling and controlling the drilling depth; they only need to drip liquid silicone and wait for it to set to complete the preparation of the orthopedic insole.

[0038] In some embodiments, a protective sleeve is provided on the outside of the insole body 1 to better protect the flexible additive 2, avoid damage to the additive, and extend the service life of the orthopedic insole.

[0039] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
