Description

Technical Field

[0001] The utility model relates to the technical field of foot and ankle correction, in particular to a double-foot three-dimensional structural difference correction insole and shoe. Background Art

[0002] Through a three-dimensional assessment screening of the foot and ankle of 576 children from grades 1 to 5 in a primary school (data property registration certificate: SZ2024120002578.0), 312 of them had severe flat feet with a single foot arch index greater than or equal to 0.3. Among these 312 severe flat feet, 126 had a foot valgus degree greater than or equal to 4°, which was moderate valgus. Among the 126 people, the degree of left foot valgus was greater than that of right foot valgus, and the height of the right foot outer arch was lower than that of the left foot outer arch. There were 50 people whose right foot outer arch height was less than or equal to 3. The detection rate of severe flat feet and moderate foot valgus was 55%, and the detection rate of flat feet and moderate foot valgus was 22%.

[0003] In this screening, among the abnormal cases of severe flatfoot and moderate foot valgus, there were 50 people whose left foot valgus degree was greater than that of the right foot, whose right foot lateral arch height was lower than that of the left foot, and whose right foot lateral arch height was no higher than 3mm, accounting for 40% of the abnormal cases of severe flatfoot and moderate foot valgus. This shows that this difference in the three-dimensional structure of the foot with left and right feet is more common in the common flatfoot valgus abnormal foot type.

[0004] The difference in the arches and foot valgus of the two feet can lead to functional inequality in the length of the two lower limbs, causing poor posture such as pelvic tilt and scoliosis.

[0005] Currently, the common corrective insoles on the market are mostly designed to treat the collapse of the medial arch of both feet or valgus of both feet. There is no differentiated adjustment for the left and right feet based on the differences in the feet. Early intervention and early diagnosis and treatment should be carried out as soon as possible based on early detection. Summary of the invention

In this way, the medial longitudinal arch support protrusion of the left foot and the medial heel support protrusion of the left foot can effectively support the medial side of the left foot of adolescents, thereby effectively solving the problem of large degree of left foot valgus. The cuboid support protrusion can be used to provide adaptive and stable support for the medial longitudinal arch position of the right foot of children and adolescents, and the right foot transverse arch support protrusion can be used to provide adaptive and stable support for the transverse arch position of the right foot of adolescents. In this way, the cuboid support protrusion and the right foot transverse arch support protrusion can effectively support the arch of the right foot of adolescents, thereby effectively solving the problem of right foot arch collapse. Therefore, the setting of the above-mentioned left foot medial longitudinal arch support protrusion, left foot medial heel support protrusion, cuboid bone support protrusion and right foot transverse arch support protrusion can effectively play a role in correcting the feet and ankles of adolescents, assist the normal growth of the feet and ankles of adolescents and effectively ensure the equal growth of the left and right feet.

[0019] According to one solution of the utility model, the left medial longitudinal arch support protrusion is a semicircular protrusion with a height of 4-5 mm and a flat top surface. With such a configuration, the height of the left medial longitudinal arch support protrusion can be determined according to the results of the examination of the foot and ankle of children and adolescents, so that the left medial longitudinal arch support protrusion can adaptively support the left medial longitudinal arch of the child or adolescent's left foot, thereby ensuring the support effect.

With such a configuration, the height of the left inner heel support protrusion can be determined according to the examination results of the foot and ankle of children and adolescents, so that the left inner heel support protrusion can adaptively support the left inner heel of children and adolescents to ensure the support effect.

[0021] According to one solution of the utility model, the cuboid bone support protrusion is a long strip (e.g., oval) protrusion with a height of 1-6 mm, and its top surface is a plane. With such a configuration, the height of the cuboid bone support protrusion can be determined according to the examination results of the foot and ankle of children and adolescents, so that the cuboid bone support protrusion can adaptively support the cuboid bone of the right foot of the adolescent, that is, support the lateral longitudinal arch of the right foot of the adolescent, and ensure the support effect.

[0022] According to one solution of the utility model, the right foot transverse arch support protrusion is a hillside-shaped protrusion, and its top surface is an inclined surface, and the side of the inclined surface close to the heel direction is lower than the side away from the heel direction. Such a configuration is made because according to biomechanics, the collapse of any longitudinal arch of the foot (including the medial longitudinal arch of the foot and the lateral longitudinal arch of the foot) will cause the collapse of the transverse arch, so the utility model designs a hillside-shaped right foot transverse arch support protrusion to support the right foot transverse arch, and at the same time supports the lateral longitudinal arch of the right foot of children and adolescents through the cuboid bone support protrusion, thereby effectively solving the problem of right foot arch collapse.

[0023] According to the scheme of the utility model, the double-foot three-dimensional structure difference correction insole and shoe of the utility model can effectively assist the normal development and growth of the feet and ankles of children and adolescents, effectively solve the problems of arch collapse and foot eversion, ensure the uniform growth of the left and right feet of adolescents, and effectively avoid the formation of bad postures such as pelvic tilt and scoliosis.

[0027] As used herein, the term “including” and variations thereof are to be interpreted as open-ended terms meaning “including, but not limited to.” The term “based on” is to be interpreted as “based, at least in part, on.” The terms “one embodiment” and “an embodiment” are to be interpreted as “at least one embodiment.”

[0028] Figure 1 A schematic diagram showing the structural arrangement of a left foot correction insole body according to an embodiment of the utility model; Figure 2The structure layout diagram of the right foot correction insole body according to one embodiment of the utility model is schematically shown. Figure 1 and Figure 2 As shown, in this embodiment, the three-dimensional structural difference correction insole for both feet includes:

[0029] Left foot correction insole body 1;

[0030] Right foot correction insole body 2;

[0031] The left foot correction insole body 1 is provided with a left foot inner side longitudinal arch support protrusion 3 and a left foot inner side heel support protrusion 4. The left foot inner side longitudinal arch support protrusion 3 is arranged corresponding to the inner side longitudinal arch of the left foot of the human body, and the left foot inner side heel support protrusion 4 is arranged corresponding to the inner side heel of the left foot of the human body;

[0032] The right foot correction insole body 2 is provided with a cuboid bone support protrusion 5 and a right foot transverse arch support protrusion 6. The cuboid bone support protrusion 5 is set corresponding to the cuboid bone of the right foot of the human body, and the right foot transverse arch support protrusion 6 is set corresponding to the transverse arch of the right foot of the human body. In this way, the left foot medial longitudinal arch support protrusion 3 can be used to adaptively and stably support the position of the left foot medial longitudinal arch of the child or adolescent, and the left foot medial heel support protrusion 4 can be used to adaptively and stably support the position of the left foot medial heel of the child or adolescent. In this way, the left foot medial longitudinal arch support protrusion 3 and the left foot medial heel support protrusion 4 can effectively support the inner side of the left foot of the child or adolescent, thereby effectively solving the problem of a large degree of left foot valgus. The cuboid bone support protrusion 5 is used to adaptively and stably support the longitudinal arch position of the right foot of children and adolescents, and the right foot transverse arch support protrusion 6 is used to adaptively and stably support the transverse arch position of the right foot of children and adolescents. In this way, the cuboid bone support protrusion 5 and the right foot transverse arch support protrusion 6 can effectively support the arch of the right foot of the adolescent, thereby effectively solving the problem of right foot arch collapse. Therefore, the above-mentioned left foot medial longitudinal arch support protrusion 3 and left foot medial heel support protrusion 4 as well as the cuboid bone support protrusion 5 and the right foot transverse arch support protrusion 6 can effectively play the role of correcting the ankle of children and adolescents, assisting the normal growth of the ankle of children and adolescents and effectively ensuring the same growth of the left and right feet.

[0033] Furthermore, if Figure 1 As shown, in this embodiment, the left medial longitudinal arch supporting protrusion 3 is a semicircular protrusion with a height of 4-5 mm, and its top surface is a plane. In this way, the height of the left medial longitudinal arch supporting protrusion 3 can be determined according to the examination results of the foot and ankle of children and adolescents, so that the left medial longitudinal arch supporting protrusion 3 can adaptively support the medial longitudinal arch of the left foot of adolescents and ensure the supporting effect.

[0034] Furthermore, if Figure 1As shown, in this embodiment, the left foot inner heel support protrusion 4 is an arc-shaped protrusion with a height of 1-4 mm, and its top surface is a plane. In this way, the height of the left foot inner heel support protrusion 4 can be determined according to the examination results of the teenager's ankle, so that the left foot inner heel support protrusion 4 can adaptively support the teenager's left foot inner heel and ensure the support effect.

[0035] Furthermore, if Figure 2 As shown, in this embodiment, the cuboid bone support protrusion 5 is a long strip (e.g., oval) protrusion with a height of 1-6 mm, and its top surface is a plane. In this way, the height of the cuboid bone support protrusion 5 can be determined according to the examination results of the foot and ankle of children and adolescents, so that the cuboid bone support protrusion 5 can adaptively support the cuboid bone of the right foot of children and adolescents, that is, support the lateral longitudinal arch of the right foot of the adolescent, and ensure the support effect.

[0036] Furthermore, if Figure 2 As shown, in this embodiment, the right foot transverse arch support protrusion 6 is a hillside-shaped protrusion (i.e., an inclined protrusion), and its top surface is an inclined plane, the side of the inclined plane close to the heel direction is lower than the side away from the heel direction, and the height of the higher side is 4-6mm, and the height of the lower side is 1-3mm. Such a configuration is made because, according to biomechanics, the collapse of any longitudinal arch of the foot (including the medial longitudinal arch of the foot and the lateral longitudinal arch of the foot) will lead to the collapse of the transverse arch, so the utility model designs a hillside-shaped right foot transverse arch support protrusion 6 to support the right foot transverse arch, and at the same time supports the lateral longitudinal arch of the right foot of the teenager through the cuboid bone support protrusion 5, thereby effectively solving the problem of right foot arch collapse.

[0037] Furthermore, in this embodiment, the heights of the left foot corrective insole body 1 and the right foot corrective insole body 2 are both less than or equal to 3 mm.

[0038] Furthermore, to achieve the above-mentioned purpose, the utility model also provides a shoe, including the above-mentioned double-foot three-dimensional structural difference corrective insole, and also including a left shoe body and a right shoe body, the left foot corrective insole body 1 is inserted into the bottom of the inner cavity of the left shoe body, and the right foot corrective insole body 2 is inserted into the bottom of the inner cavity of the right shoe body.

[0039] In this embodiment, the left shoe body and the right shoe body can be any shoe body currently on the market that is worn by children and adolescents and that requires insoles, such as various types of sports shoes, travel shoes, leather shoes, cloth shoes, sandals, slippers, etc. As long as the relevant shoe body requires insoles to be worn, it can be used as the left shoe body and the right shoe body in this embodiment.

[0040] According to the above scheme of the utility model, the double-foot three-dimensional structure difference correction insole and shoe of the utility model can effectively assist the normal development and growth of the feet and ankles of children and adolescents, effectively solve the problems of arch collapse and foot eversion, ensure the uniform growth of children's left and right feet, and effectively avoid the formation of bad postures such as pelvic tilt and scoliosis.
