Technical Field
The invention belongs to the field of medical product production, and particularly relates to a method for manufacturing a high-simulation artificial ear.
Background
Auricular deformity refers to abnormal morphology or structure of the exposed part of the ear, and usually includes congenital auricular deformity and postnatal auricular deformity. Not only can the auricular deformity cause the cosmetic defect, but also the auricular deformity can have negative influence on the human psychology. Common treatment methods for auricular deformity include ear reconstruction surgery, artificial ear wearing, and the like.
Wherein, the ear reconstruction operation is to carve the costal cartilage of the patient into a fine ear support to be planted at the position of the deformed ear and carry out the repair work of wound grafting and the like. The auricle made by this method cannot fully show the fine structure of the ear, such as the auricular boat, the cavity of the ear clip, etc. And pleural injury may be caused in the process of taking costal cartilage, and serious consequences such as incapability of spontaneous breathing of a patient and the like are finally caused due to hemopneumothorax. In addition, complications such as deformity of the chest and scar hyperplasia may occur. This method is gradually replaced by wearing artificial ears, which requires high physical condition and age of the patient and has a high risk of operation.
However, the currently common wearing method of the artificial ear is firstly to punch a titanium alloy fixing frame on the bone around the ear of the patient, and then to complete the wearing through the complicated steps of multiple times of reverse molding, plaster mold manufacturing, silica gel artificial ear manufacturing and the like. Compared with the ear reconstruction operation, the method has small wound, can replace the artificial ear according to the requirement, has the defects that the bracket still needs to be implanted in the operation, the manufacturing process of the silica gel artificial ear is complex, and the plaster mold is not easy to store, so that the artificial ear is difficult to copy, and the artificial ear manufacturing method which has small risk, high simulation degree and simple and convenient operation becomes a difficult problem which is urgently needed to be overcome in the medical field.

step S41, selecting a pigment according to the skin color of a patient, and preparing a silica gel solution;
step S42, pouring the silica gel into the artificial ear mold, pressing the mold, and curing and molding;
step S43, taking out the silica gel artificial ear, trying and color debugging to form the final user parameter, and archiving for standby.
The color adjusting step is added in the subdivided artificial ear manufacturing step, the color of the silica gel liquid can be adjusted according to the skin color of the patient, so that the color difference between the artificial ear and the skin around the residual ear is reduced, the artificial ear has higher simulation degree, and the artificial ear draws less attention of other people.
Further, the silicon rubber material in step S40 is medical silicon rubber, and the use of such material can reduce discomfort such as allergy generated by the artificial ear wearer.
Further, the glue in step S50 is medical glue, and the use of the glue can reduce the uncomfortable reactions such as itching and ulceration caused by long wearing time of the artificial ear.
Furthermore, before step S50, the artificial ear is repaired by edging and the like as required, and capillaries can be carved, ear holes can be pierced and the like according to the special conditions of the patient, so as to achieve the effect of no difference with the healthy ear.
The artificial ear manufactured by the invention has high simulation degree, the final effect is almost not different from that of the real ear, the process is simple, the operation is easy, and the artificial ear can be manufactured without the patient going to the site under the condition of storing the relevant data of the patient. Moreover, the artificial ear is convenient to wear and high in safety, and risks brought by operations are eliminated.
