Technical Field

The utility model relates to the technical field of medical equipment, more accurately say and relate to an auricle orthopedic device.

Background

Congenital auricular deformity is a common head-face deformity, mainly comprising auricular structure deformity and auricular morphology deformity, wherein the structural deformity is mainly skin and cartilage tissue abnormality caused by abnormal development of auricles in an embryonic period. Clinical manifestations of malformed ears come in many forms, such as jug ears, cupped ears, cryptophytes, etc. It is known that auricular deformity not only causes aesthetic cosmetic defects, but also affects the physiological (hearing) and psychological development of the infant patient. Congenital auricular deformity has a high incidence rate, especially morphological deformity is common.

Although many orthopedic surgeries are quite mature at present, the surgeries are usually performed until the auricle malformation reaches adolescents, the auricular cartilage of the sick children is relatively mature, surgical correction treatment can bring surgical wounds, and anesthesia and possible complications applied during the surgeries can bring great risks to the surgeries.

The earliest non-surgical reports of correction of ear deformities were several japanese plastic specialists in the 80's of the 20 th century. They propose to give the neonate a non-operative treatment in an early stage and achieve a good therapeutic effect. To date, non-surgical treatments have been developed. Currently, there are four main approaches to such non-surgical treatment: one, only surgical tape or bandage. Secondly, plastic composition + surgical tape or bandage. Thirdly, splint therapy: mainly adopts a filiform splint and adhesive tape or bandage. And fourthly, an EarWell Infant Ear Correction System, wherein the model mainly comprises 1 rear base, 2 Ear rim retractors, 1 concha cavity former and 1 front cover with holes.

However, the non-operative treatment methods can not restore the deformed ear well, can not simulate the shape of the normal ear, and are complicated to operate.
