Description

Preparation process of finished orthopedic shoes

technical field

The invention relates to an orthopedic device, in particular to a preparation process of a finished orthopedic shoe.

Background technique

Traditional foot orthoses (FO) and ankle-foot orthoses (AFO) are custom-made orthotics, which require plaster molding for each patient, and the process is complicated; at the same time, their structure is simple and the material is relatively hard. When the patient wears it, the hard orthosis directly contacts the patient's feet and lower legs, which is easy to cause wear and tear. In addition, the material has poor air permeability, so the comfort is poor. From the perspective of orthopedic effects, the fixed range of traditional orthotics is constant, and it is not very flexible to subdivide and adjust according to the specific condition of the patient, so the indications are vague; and the level of personalized production is different, so it is difficult to guarantee the orthopedic effect. On the other hand, since the orthosis takes up a lot of space, it is generally necessary to wear loose shoes that are one to two sizes larger, so they are mostly sneakers; moreover, the orthosis is directly exposed to the outside, which looks clumsy and alternative. Traditional ankle-foot orthoses This is especially true for AFO, which affects the user's image and causes greater psychological pressure. Traditional orthopedic shoes use shoemaking technology, and only ordinary materials are used in the shoes to strengthen the strength of the shoes. The strength and elasticity of the materials are poor, and they are easy to deform after wearing. The fixation is too rigid and inelastic, and there is no elastic playback during sports; The upper part is mostly fixed on the heel part with steel rods.

Contents of the invention

In view of the deficiencies and defects of traditional orthotics and orthopedic shoes, the invention combines traditional orthotics and shoes into one, and discloses a preparation process for finished orthopedic shoes that are comfortable, convenient and have good orthopedic effects.

Technical solution of the present invention is as follows:
