Technical Field

[0001] The utility model relates to the field of insoles, in particular to a hallux valgus rehabilitation insole. Background Art

[0002] Hallux valgus, also known as hallux valgus deformity, refers to the deviation and displacement of the big toe at the first metatarsophalangeal joint. The main causes of its formation include foot diseases and bad foot habits. Foot diseases include flat feet, rheumatoid arthritis, neuromuscular lesions, and balance dysfunction of soft tissues such as foot muscles and tendons; bad foot habits include long-term wearing of pointed shoes and high heels. Among them, bad foot habits can squeeze the big toe, and long-term squeezing and friction cause the hallux valgus to gradually worsen. The treatment methods for hallux valgus mainly include surgical treatment and rehabilitation treatment. Surgical treatment includes osteotomy and soft tissue surgery, which are mainly for severe hallux valgus deformity, ineffective rehabilitation treatment or severe pain that affects daily life; and rehabilitation treatment generally refers to the use of orthopedic braces, hot compresses and massage to delay the progression of the disease or help the thumb return to normal shape after normalizing foot habits. Among the two treatment methods mentioned above, rehabilitation therapy is the most widely used and most commonly used treatment method, and in rehabilitation therapy, the use of orthopedic braces is the most common.

[0003] At present, orthopedic braces used for hallux valgus rehabilitation treatment mainly include orthopedic shoes and orthopedic insoles. For example, the Chinese utility model patent with the authorization announcement number CN220404224U discloses a hallux valgus orthopedic insole, including: an insole base, a hallux valgus orthopedic component is provided on the upper part of the insole base, the hallux valgus orthopedic component includes a fixed sleeve, a hallux valgus orthopedic sleeve and an elastic traction belt, the fixed sleeve is fixedly mounted on the upper part of the insole base, and the fixed sleeve is arranged near the head of the insole base, the hallux valgus orthopedic sleeve is fixedly mounted on the upper part of the insole base, and the hallux valgus orthopedic sleeve is located at the front of the fixed sleeve, the position of the hallux valgus orthopedic sleeve corresponds to the position of the big toe of the human foot, the elastic traction belt is sewn on the front edge of the fixed sleeve, and the elastic traction belt passes through the junction of the hallux valgus orthopedic sleeve and the fixed sleeve. This orthopedic insole can provide an inward traction force to the root joint of the big toe of the foot through the elastic traction belt, and realize the correction of the hallux valgus in the long-term use process. However, during the research process, we found that the use of this insole would cause the other toes to gather in the opposite direction towards the big toe, which affected the correction effect. Summary of the invention

[0004] The main purpose of the utility model is to provide a hallux valgus rehabilitation insole, aiming to solve the technical problem that other toes will gather towards the hallux in the opposite direction during the use of the existing correction insole, thus affecting the correction effect.

[0005] To achieve the above-mentioned purpose, the utility model proposes a hallux valgus rehabilitation insole, comprising an insole body, wherein the insole body comprises, from top to bottom, a sweat-absorbing layer, a support layer and a buffer layer which are fixedly connected to each other, the support layer comprises a heel area, an arch area and a sole area, a thumb limit baffle is arranged at the toe gap corresponding to the big toe in the sole area, the thumb limit baffle comprises a fixed part and a limiting part, the limiting part comprises a connecting end fixedly connected to the fixed part and free ends located on both sides of the connecting end, the free end and the connecting end form a U-shaped structure, a wrapping sheet is arranged at the outer edge of the first metatarsal bone corresponding to the sole area, and the material of the support layer is thermoplastic plastic.

[0025] Please refer to Figures 1 to 5The utility model provides a hallux valgus rehabilitation insole, comprising an insole body, wherein the insole body comprises, from top to bottom, a sweat-absorbing layer 01, a support layer 02 and a buffer layer 05 which are fixedly connected to each other, the support layer 02 comprises a heel area 021, an arch area 022 and a sole area 023, a thumb limit baffle 06 is arranged at the corresponding toe gap of the big toe of the sole area 023, the thumb limit baffle 06 comprises a fixing portion 061 and a limiting portion 062, the limiting portion 062 comprises a connecting end 063 fixedly connected to the fixing portion 061 and free ends 064 located on both sides of the connecting end 063, the free end 064 and the connecting end 063 form a U-shaped structure, a wrapping sheet 024 is arranged at the outer edge of the first metatarsal bone corresponding to the sole area 023, and the material of the support layer 02 is thermoplastic plastic. The sweat-absorbing layer, the support layer and the buffer layer are fixedly connected by adhesive, and a baffle notch 011 is set at the sweat-absorbing layer corresponding to the thumb limit baffle, and the thumb limit baffle is allowed to protrude above the sweat-absorbing layer. During use, the thumb limit baffle is stuck in the gap between the big toe and the second toe, and then the sole and heel are naturally adjusted and attached to the sweat-absorbing layer of the insole body. The wrapping sheet presses the first metatarsal bone of the patient's foot inward, and the big toe is gradually adjusted. At the same time, the thumb limit baffle also provides support for the big toe in the opposite direction, and the thumb limit baffle can also prevent other toes from approaching the big toe, ensuring the correction effect of the hallux valgus. At the same time, since the material of the supporting layer is thermoplastic material, in the process of making the insole from a semi-finished product into a finished product, or in the actual use of the patient, the insole body can be heated first. Through the pressure of the patient's foot and the pressing of the wrapping part, the insole body can be cooled down so that it can better fit the sole of the patient's foot, and the correction effect is better. As the correction treatment improves, the shape of the insole can be gradually adjusted to achieve the function of continuous adaptive correction.

[0026] Since the gap between the big toe and the second toe has an arc-shaped edge, in one embodiment, a plurality of first breaking grooves 065 are provided at the free end 064 of the limiting portion 062. The first breaking grooves are perpendicular to the direction of the connection end, and during use, the free end of the limiting portion after heating can be squeezed to have a surface curvature that better fits the gap between the patient's fingers, and the presence of the first breaking grooves makes it easier for the free end to deform.

[0027] In order to facilitate mass production, in one embodiment, a plug-in slot 025 is provided at the corresponding big toe joint of the sole area 023, and the fixing portion 061 of the thumb limit baffle 06 is plugged and fixedly connected with the plug-in slot 025. A clearance groove 026 is provided at the bottom of the plug-in slot 025 of the sole area 023, and a supporting piece 066 matching the clearance groove 026 is provided on the fixing portion 061 of the thumb limit baffle 06. The fixing portion of the thumb limit pawnshop is inserted into the plug-in slot, and the supporting piece plays a role in preventing the fixing portion from escaping from the plug-in slot. At the same time as the plug-in, the interface of the plug-in connection is bonded and connected with adhesive, which can play a role of further reinforcement. That is, by modularly producing the components of the insole support layer, the modeling and mass production of the insole can be realized.

[0028] In one embodiment, the limiting portion 062 of the thumb limiting baffle 06 is connected to the thickening piece 067. For a patient with hallux valgus with severe first metatarsal deformity, after correction of the hallux, the gap between the hallux and the second toe is wider, and the width of the limiting portion can be increased by the thickening piece. In the subsequent correction process, the thickening piece can also be taken out through the hole to adapt to the gradually smaller and normalized gap between the hallux and the second toe.

[0029] In another embodiment, an arch pad 07 is further provided at the bottom of the arch area of ​​the support layer 02, a second broken groove 026 is provided at the arch area 022 of the support layer 02, and a third broken groove 071 corresponding to the second broken groove 026 is provided at the arch pad 07. Generally, hallux valgus patients often have arch deformities due to long-term foot habits. The arch pad can increase the support of the insole body to the arch, and the third broken groove of the arch pad and the second broken groove of the support layer can make it easier to adjust the arch area after heating the insole body to fit the arch of the patient's foot.

[0030] The buffer layer 05 is made of Hypoli material, and the sweat-absorbing layer 01 is made of Hypoli material. Hypoli is an environmentally friendly high-polymer sponge with the characteristics of breathable moisture absorption, antibacterial deodorization, cushioning and shock absorption, environmental protection and light weight. Special functional materials such as mildew and antibacterial agents, spices, activated carbon, cork chips, antistatic materials, etc. can also be added, and have corresponding effects. The sweat-absorbing layer is covered with a cotton cloth layer (not shown). The sweat-absorbing layer covered with a cotton cloth layer can increase the comfort of the insole, and it is also more convenient to print on the surface of the insole, thereby increasing the sensory effect of the product.

[0031] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
