Modeling method and manufacture method of auricular support capable of exposure prevention, and auricular support

Abstract

The invention provides a modeling method and manufacture method of an auricular support capable of exposure prevention, and the corresponding auricular support. Based on an artificial ear support, ear support data is collected; data modeling is conducted; ear support and skin data is introduced; finite element analysis is used to simulate force bearing states of each part after implantation of the ear support; and finally, simulation results are compared with clinical results, and stress concentration parts are adjusted, so that carving of the support can be guided, and exposure of the support caused by stress problems can be prevented effectively.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering external components, in particular to a modeling method, a manufacturing method and a corresponding auricle support for preventing exposure. Background technique [0002] At present, the incidence of microtia is on the rise all over the world, which may cause heavy burden and economic pressure on patients' normal psychological and physical development, patients' families and even society. Total ear reconstruction surgery is generally divided into stage III. There are many surgical methods, all of which require selection of appropriate auricle brackets and skin covering tissues. Autologous costal cartilage or Medpor ear stents are generally used as materials for auricle stents, and a combination of these two materials is also used. However, after total ear reconstruction, the complication of stent exposure often occurs. It is difficult to deal with the exposure of the stent, and som...

Problems solved by technology

It is difficult to deal with the exposure of the stent, and sometimes the implanted stent needs to be removed, which eventually leads to the failure of the operation
