Individualized auricle fixer after auricle reconstruction and preparation method thereof

Abstract

The invention belongs to the field of rehabilitation medical treatment, and discloses an individualized auricle fixer after auricle reconstruction. The individualized auricle fixer comprises one or two of an auriculocranial part and an cavum conchae part, an anti-scar material and a concave-convex structure; the anti-scar material coats an adhering surface of the auriculocranial part and the skinof an ear; the cavum conchae part and the auriculocranial part are mutually connected; the concave-convex structure is positioned on the outer wall of the cavum conchae part; and the maximum cross section of the cavum conchae part is positioned in the boundary of the minimum cross section of the concave-convex structure. A gap is included between the cross-sectional boundary of the cavum conchae part and a minimum circumference capable of covering the boundary of the concavo-convex structure. According to the invention, the problems of difficult cutting and low compliance of patients in a daily use process of scar plaster are solved; a silicon gel coating layer with silicone is adopted, so that the treatment effect on scar is enhanced, and skin pruritus and discomfort induced by long-termwearing are reduced; and the fit degree is high, a special design of the concave-convex structure increases wearing stability, and bonding strength of the fixer is increased.

Description

technical field [0001] The invention belongs to the field of rehabilitation medicine, in particular to an individualized auricle fixer after auricle reconstruction and a preparation method thereof. Background technique [0002] Congenital microtia is the second largest congenital developmental deformity of the face, with a high incidence rate, which affects the appearance and psychological development of patients. Autologous costal cartilage auricle reconstruction currently used in China is an important means to improve the patient's appearance and restore the patient's self-confidence. Auricle reconstruction is divided into three phases: the first phase is the implantation of the retroauricular expander, that is, a skin expander of a specific size is embedded subcutaneously in the mastoid area of ​​the patient's residual ear, and the skin behind the ear is regularly injected with water to expand the skin behind the ear; the second phase is the application of The autologous...
