Description

Vacuum-shaped corrective insole

The invention relates to a corrective insole, in particular to a modified insole capable of vacuum shaping and quickly correcting the foot to maintain a correct posture, so as to effectively support the "foot arch" of the "flat foot" patient and avoid the "foot arch". The problem of subsidence continues to deteriorate, and effectively guides the problem of "calcaneus" eversion of patients with "valgus".

Press, "flat feet" is not a disease, but means that the "foot arch" is lower. The "foot arch" is the concave part of the inner side of the foot. When people perform activities such as standing, walking, running or jumping with their feet, " The arch of the foot can help maintain the balance and support of the body, and provide a good shock-absorbing cushioning capacity to alleviate the various pressures on the foot during the activity and the reaction force from the ground. The lack of a "foot arch" is prone to foot acid. The situation of fatigue, fall, etc., and even the resulting load-bearing axis changes, which in turn leads to problems of knee and hip wear in the future. Clinically, "flat feet" can be divided into two types. Most patients with "flat feet" will have a "foot arch" when the foot is suspended. This is a "soft flat foot". Conversely, if the foot is not empty, there is no "foot". "Bow" is a "structural flat foot". Most of the congenital anomalous feet belong to "structural flat feet."

Generally speaking, from the time of birth to the age of two years, the foot of the child is cartilage, the fat inside the foot has a thick fat pad, and the ligament is slack, so the "foot arch" is not obvious. According to statistics, under two years old. Because the muscle ligaments have not yet matured, they are almost all "flat feet", but since the age of two, as the children slowly learn to walk and gradually use the strength of the toes, heels and soles, the muscle ligaments of the "foot arches" will gradually When the development is completed, the "foot arch" is gradually formed. By the time of the fourth year of age, the activity of the child has increased, which is the period of rapid growth of the "foot arch". According to a large number of screenings and surveys conducted by internationally renowned medical journals (Pediatrics) for preschool children aged 3 to 6, it is found that children aged 3 to 6 have an average incidence of 44%, although with age, "flat feet" The incidence will drop, but such a high incidence is still worthy of extra attention as a parent.

However, what is meant by "flat feet"? What is the "overturned foot"? Please refer to Figure 1. Figure 1 (a) shows "Flat Foot", commonly known as "Duck Foot", which refers to the phenomenon that the "longitudinal arch" of the sole is low (as indicated by the dotted line). And "lower foot arch" is also called "opening foot", 90% of children are caused by weight load during development; and Figure 1(b) is "Pronated Foot" (Pronated Foot) ), that is, "calcaneus" valgus (as indicated by the dotted line on the left foot), the calcaneus valgus will cause the body's gravity line to be not evenly transmitted to the foot, thus indirectly causing the knee joint and the spine The burden, and often combined with knee valgus (X-leg) and lower back pain.

Because the musculoskeletal system of children aged 1 to 6 is at a stage of rapid development and integration, not all children's musculoskeletal system's self-balancing mechanism works well. If the musculoskeletal system is more than reasonable, You should seek correction as soon as possible so as not to miss the golden correction period. For example, children with severe "overturned foot" and "flat feet" have an "flat foot" phenomenon due to their underdeveloped ligaments and muscles. At this time, if the "valgus" is beyond reasonable range Not only will it seriously undermine the balance of biomechanics of the lower extremities, so that every step of the child will be unsteady, and the problem will be that the body's weight will not be scattered evenly due to the weight of the body, and the body's gravity line will be shifted in the future. Under the circumstances, it is necessary to customize a "corrective shoe" or "corrective insole" according to the individual needs to effectively support the "foot arch" and prevent the "foot arch" from collapsing and continue to deteriorate. The problem of guiding the gravity line offset.

The purpose of tailor-made tailor-made "corrective shoes" or "corrective insoles" is to help children guide the development of bones and muscles as early as possible to avoid irreparable deformities in the future. After all, children's foot bones and muscles are like saplings. Like the roots, if it is tilted immediately, if it can be immediately corrected, as the years grow, the roots of the tree will naturally lead back to the correct position. However, the tailor-made tailor-made "corrective shoes" or "corrective insoles" Not only do you have to wait for a few weeks, but the cost is not too high. It takes thousands to tens of thousands of dollars, and the children in the developmental period must be replaced regularly, and they have corrective effects. Therefore, for some parents, it will undoubtedly cause economics. A heavy burden on it.

Accordingly, how to design a corrective insole, in addition to enabling the corrective insole to be formed quickly and immediately, so that the patient can obtain a customized tailored insole at a low price without waiting after the order. In addition, the three-dimensional correcting configuration formed on the corrective insole not only has moderate elasticity, but also can fully match the overall or partial configuration of the patient's foot. Correction of the problem to effectively correct the aforementioned "flat feet" and "valgus feet" has become an important problem to be solved by the present invention.

In view of the customary tailor-made orthotic shoes or orthopedic insoles, which are expensive and time-consuming to manufacture, the inventors have finally designed this book after many years of practical experience. The invention can be a vacuum-shaped corrective insole, so that the patient can obtain a customized tailored insole at a low price immediately without waiting.
