Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an auricle shape orthosis and a preparation method thereof, and particularly relates to personalized manufacture.
Background
Congenital external ear deformities are classified into auricle morphological deformities and auricle structural deformities. The malformation of auricle morphology, i.e. the deformation of auricle, has no defect of skin and cartilage structure. The domestic report shows that the incidence rate of the auricular morphological deformity of the newborn is about 43.36 percent, wherein only about 30 percent of the auricular morphological deformity is self-healed, and the other auricular morphological deformity is maintained as the original state and even develops more seriously. Auricular deformities have adverse effects on the mental development and social activities of children, and often require surgery for correction.
Japanese plastic specialists first proposed a non-surgical treatment plan in 1984, and thereafter developed the treatment in succession in various countries. The principle of the orthopedics is that the estrogen level in the newborn is higher, so that the ear cartilage has small elasticity and strong plasticity. The auricle shape is shaped by the orthosis, and the auricular cartilage shape is determined according to the shaped shape along with the reduction of the estrogen level in the newborn.
Morphological deformities common to congenital morphological deformities of auricles include: jug ears, cupped ears, drooping ears, Stahl ears, crinkle ears, Conchal crus ears, helix deformities and complex deformities. The above mentioned common deformities are mainly manifested by some or all morphological abnormalities of the auricle, the auricular boat and the antihelix. The purpose of the orthosis is to restore and maintain the configuration of the structure.
The auricle orthoses in the prior art are various in types and good in orthodontics effect, but are often complex in structure and non-personalized, doctors or professionals are required in operation, and parents cannot take down the auricle orthoses to clean the skin and then wear the auricle orthoses again in the process of wearing the auricle orthoses. Secondly, the partial appliance needs to be adhered to the skin at the same part for a long time by adopting a glue material, so that the skin eczema, the skin ulceration and the like are easy to happen. Thirdly, most of the malformed ranges of the auricle morphological deformities are local, the wearing range of most of the existing orthotics is too large, the stimulation to the skin at the normal position is increased, and the comfort level is not good enough.
Therefore, it is necessary to provide an auricle shape orthosis and a method for manufacturing the same to overcome the disadvantages of the prior art.

An addition type medical silica gel filling mold is adopted, A, B two components are prepared in a ratio of 1:1, and the mold is filled after uniform stirring. And (5) removing the mold after the silica gel is solidified into a solid state, and trimming the edge. The shore hardness of the silica gel is 30.
An auricle shape orthosis using method comprises the following steps:
the appliance is soft and has good elasticity. When the ear ring patch is used, the front plate and the rear plate are opened, the ear ring barrier is placed on the ear boat at the malformed position, and the ear ring is confirmed to be flatly attached to the inner wall of the ear ring barrier. The front plate and the auricle are fixed, the back plate is buckled behind the auricle backwards, and the antihelix plate is correspondingly placed behind the antihelix. At this time, the formation of the helix and the canoe is completed. The front plate of the corrector is adhered by a 3M low-sensitivity suture-free adhesive tape, and the other end of the adhesive tape is adhered to the skull skin. When the adhesive tape is pasted, the back plate of the corrector is pasted on the skull backwards, and the formation of the antihelix is completed.
