Auricle growth-promoting device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an auricle growth promoter.

Background

Congenital auricle deformity is a relatively common congenital body surface deformity, and about 5% of newborns have auricle deformity with different degrees according to epidemiological statistics, such as auricle deformity of tremella, calicivirs, tremella annulata, stahl ears and the like. The difference of the auricle deformity degree is large, and the auricle deformity degree is changed from the auricle outline size and the auricle outline, and part of the auricle subunit structure is deleted, and then the whole auricle structure is deleted. Most of the auricle deformities of newborns can be improved by an early non-operative intervention method, and later operative treatment is avoided. And for the infant with serious auricle deformity, the early non-operative treatment can also obviously reduce the difficulty of the later-stage operation, and a better treatment effect is obtained. Since most of the auricle morphology deformities can be corrected noninvasively during infancy through early intervention, surgery for correction is not necessary until 6 years of age. The auricle structure of the newborn has the characteristics of good ductility and strong plasticity within 3 months of birth. The principle of the early non-operative treatment method is that the deformed auricle structure is subjected to physical and mechanical stretching and expansion, and the auricle is promoted to grow and reach a normal physiological structure through long-term stretching and growth promoting effects.

In the prior art, the mobility of the base of the corrector is large, the design is unreasonable, the fixation of the device after the retractor is inserted into the slot is not facilitated, the treatment effect of the corrector is affected, and therefore, the corrector has the need of further improvement.
