Auricle shape orthosis and manufacture method thereof

Abstract

The invention discloses a local orthosis capable of individually manufacturing a malformed position, can reduce interference to other positions, has a simple wearing method and is comfortable for a patient to wear. The orthosis comprises a front plate, a rear plate, a connecting plate, a helix baffle plate and an anthelix plate, wherein the front plate, the rear plate, the connecting plate, the helix baffle plate and the anthelix plate are in integral forming; the anteroposterior view of the local orthosis is of a "sector" shape, and the section of the local orthosis is of a shape of n of which the opening faces leftwards. The orthosis shapes the helix and the scapha through the main function of the front plate and the helix baffle plate; and through the main function of the rear plate andthe anthelix plate, the anthelix is shaped. The orthosis has a clipping and fixing function, the shapes of the helix, the scapha and the anthelix are effectively maintained, and the orthosis is unlikely to fall. A manufacture method for the local orthosis comprises the following steps of: S1: collecting data: shooting auricle front side and side surface photos with scales; S2: carrying out modeling: according to the size of the auricle and an anticipated corrected ear shape, designing the model of the orthosis; S3: carrying out reverse modeling: designing a mould of the orthosis; S4: printingthe mould; and S5: carrying out glue filling and forming.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auricle shape orthosis and a preparation method thereof, in particular to personalized production. Background technique [0002] Congenital external ear deformities are divided into auricle morphological deformities and auricle structural deformities. Morphological deformity of the auricle is deformation of the auricle without defects of skin and cartilage structure. It is reported in China that the incidence rate of neonatal auricle deformity is about 43.36%, and only about 30% of them heal spontaneously, and the others maintain their original shape or even develop more seriously. Auricle deformities have adverse effects on children's psychological development and social activities, and often require surgery for correction. [0003] In 1984, Japanese plastic experts first proposed a non-surgical treatment plan, and then various countries have carried out this treatm...

AI Technical Summary

Problems solved by technology

[0005] There are various types of auricular orthoses in the prior art, and the orthopedic effect is good, but they are often complex in structure and non-personalized. The operation requires doctors or professionals. During the process of wearing the orthosis, parents cannot take it off and clean the skin before wearing it again.

Secondly, some aligners need to use glue to adhere to the skin of the same part for a long time, which may easily cause skin eczema, ulceration, etc.

Third, most of the deformities of the auricle are localized. At present, most of the orthotics are worn over a large range, which increases the stimulation of the normal position of the skin, and the comfort is not good.
