Problems solved by technology

Therefore, the production cycle of artificial ear is long, which is very inconvenient for foreign patients.
Moreover, the mold die-casting and prosthesis in the production process are heavy, making it difficult to reduce weight

Embodiment 1

[0041] Such as figure 1 , figure 2 As shown, the artificial ear 100 includes an embryo body 101 and a coating 110 . The embryo body 101 includes an auricle 102 and a chassis (not shown in the figure). The pinna 102 is integrally formed with the chassis. The auricle 102 is imitated in the shape of a real auricle. The chassis is used for bonding with the head of the person wearing the prosthetic ear 100 . The embryo body 101 can be made of silica gel or human body silica gel. When making, it can be made by 3D printing technology. As an optional manufacturing method, the embryo body 101 can also be manufactured using a mold.

[0042] The coating 110 is coated on the surface of the embryo body 101, and the coating 110 may be one layer, or two or more than two layers. The number of layers of the coating 110 is determined according to actual needs. The coating 110 is a photosensitive resin, also called a UV resin, which can be cured by ultraviolet light. Pigments are added...

Embodiment 2

[0045] Such as image 3 , Figure 4 As shown, a prosthesis 200 of a human hand includes an embryo body 201 and a coating 210 . The embryo body 201 is made into the shape of a human hand and is suitable for being worn on the arm. The embryo body 201 can be made of silica gel or human body silica gel. When making the embryo body 201, it can be made by 3D printing technology. As an optional manufacturing method, the embryo body 201 can also be manufactured using a mold.

[0046]The coating 210 is coated on the surface of the embryo body 201, and the coating 210 may be one layer, or two or more than two layers. The number of layers of the coating 210 is determined according to actual needs. The coating 210 is a photosensitive resin, also called a UV resin, which can be cured by ultraviolet light. Pigments are added in the coating 210 to make the coating 210 present a desired color. When multiple layers of coating 210 are used, the color of each layer of coating 210 may be t...

Abstract

The invention relates to a prosthesis and a prosthetic ear. The prosthesis comprises a blank body and a coating, wherein the coating is coated to the surface of the blank body. The prosthesis and the prosthetic ear in the invention have the following effects: 1, natural transition of the color of the prosthesis can be realized through color modulation of a flexible photosensitive material and multi-layer covering type light curing, and a simulation effect is achieved; 2, a mold is not needed when the prosthesis in the invention is manufactured, the process can be accelerated, and cost is saved; 3, chromatic aberration can be continuously adjusted in a layered photocuring process, and the rate of defective goods is eliminated; 4, the manufacturing period is only 3 days, and only 2 minutes are needed for each adjustment. and 5, the photosensitive material is low in density, anda filling rate can be selected in initial printing to further reduce the weight.

Description

technical field [0001] The invention relates to a prosthesis and an artificial ear. Background technique [0002] The use of prosthetics is a common treatment method for patients with missing or incomplete organs, such as the use of prosthetics to make up for amputee or incomplete limbs, and the use of prosthetic ears to deal with auricular deformities. [0003] Auricle deformity refers to the abnormal shape or structure of the exposed part of the ear, usually including congenital auricle deformity and acquired auricle deformity. Deformity of the auricle will not only cause defects in appearance, but also have a negative impact on people's psychology. Common treatment methods for auricle deformity include ear reconstruction surgery, artificial ear wearing, etc. [0004] Among them, the ear reconstruction surgery is to take the patient's costal cartilage and carve it into a fine ear bracket and implant it in the deformed ear, and perform repair work such as wound skin graft...
