Description
Technical Field
The invention relates to a prosthesis and an artificial ear.
Background
The prosthesis is a common treatment method for patients with organ deficiency or unhealthy patients, such as using artificial limbs to compensate amputees or limbs with incomplete limb defects, and using artificial ears to treat auricular deformities.
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.
The common artificial ear wearing method at present is firstly to punch a titanium alloy fixing frame on bones around ears of a patient, and then the titanium alloy fixing frame is completed through the complex steps of multiple times of reverse molding, stone mold manufacturing, silica gel artificial ear manufacturing and the like. Compared with the ear reconstruction surgery, the method has small wound, can replace the artificial ear according to the needs, has the defects that the bracket is still required to be implanted in the surgery, the manufacturing process is complex, the plaster mold is not easy to store, the artificial ear is difficult to copy, the artificial ear can be taken down through the surgery, and is very inconvenient; meanwhile, the existing artificial ear has single function and low acceptance of patients.
In addition, the commonly used artificial ear has difficulty in achieving highly simulated color matching and color transition. So that the existing artificial ear can only be respectively toned through different parts of human silica gel and is formed by manual or 3D printing die-casting. Although the human body silica gel prosthesis is vivid, the efficiency is low, the manufacturing period is long, and the rejection rate is high. 3 weeks are needed from the mode taking and color matching to the completion of the manufacturing, 1-3 weeks are needed for the correction and adjustment of the mold, and 2-3 days are needed even if only the color is adjusted. Therefore, the artificial ear has a long manufacturing period and is very inconvenient for the patient to go to the outside. And the die casting and the artificial ear in the manufacturing process have large weight and are difficult to reduce the weight.
For a patient wearing the prosthesis, the closer the color of the prosthesis is to other parts of the body, the less easily the prosthesis can be seen as the prosthesis, which is particularly important for reducing the discrimination of other people and enhancing the confidence of the patient.
For a real body, the surface skin color of each person is different. Moreover, for each person, the skin color of the adjacent parts also has color difference and is gradually changed; the color of the human body is gradually changed from inside to outside, and blood vessels and the like can be seen through the skin at some parts. Therefore, how the color of the surface of the prosthesis is closer to the real color of the human body and the effect of color gradual change is achieved, which is an important factor for measuring the quality of the prosthesis.

Detailed Description
Example 1
As shown in fig. 1 and 2, an artificial ear 100 includes a blank 101 and a coating 110. The blank 101 comprises a pinna 102 and a chassis (not shown). The pinna 102 is integrally formed with the chassis. The pinna 102 mimics the shape of a real pinna. The chassis is used for bonding with the head of a person wearing the artificial ear 100. The blank 101 may be silica gel or human silica gel. When in manufacturing, the film can be manufactured by using a 3D printing technology. As an alternative manufacturing method, the blank 101 may be manufactured by using a mold.
The coating 110 is coated on the surface of the blank 101, and the coating 110 may be one layer, or two or more layers. The number of layers of the coating layer 110 is determined according to actual needs. The coating 110 is a photosensitive resin and a UV resin, and can be formed by ultraviolet curing. Pigments are added to the coating 110 to make the coating 110 take on a desired color. When multiple coatings 110 are used, the color of each coating 110 may or may not be the same. When different colors are selected for each layer of coating 110, the effect of gradient color can be made, so that the color of the coating is closer to the color of a real ear. Each coating layer 110 can be coated on the whole surface of the blank 101 or on a partial surface. When the color of a certain layer of coating 101 is not good or the manufacturing is not ideal, a layer of coating 110 can be coated to cover the coating, so that waste caused by scrapping is avoided. In order to make a more realistic artificial ear 100, blood vessels can be drawn on the surface of the blank 101 or on a certain coating 110, and then the coating 110 is coated to cover the blood vessels, so that the simulation effect is better.
In the artificial ear 100 of the present embodiment, the blank 101 is made of human silica gel by 3D printing. The photosensitive resin used for the coating 110 is photosensitive acrylated epoxy resin, photosensitive unsaturated polyester, photosensitive polyurethane, or photosensitive polythiol/polyene photocurable resin, in the embodiment of the present invention, the photosensitive resin is photosensitive polyurethane, abbreviated as TPU. After each volume of coating 110 is coated, ultraviolet light is used for irradiation curing and forming. The bottom plate 103 is coated with glue to adhere the artificial ear 100 to the head of the wearer.
Example 2
As shown in fig. 3 and 4, the prosthesis 200 of the human hand comprises a blank 201 and a coating 210. The blank 201 is shaped like a human hand and is suitable for being worn on an arm. The blank 201 may be silica gel or human silica gel. When the blank 201 is manufactured, a 3D printing technique may be used. As an alternative manufacturing method, the blank 201 may be manufactured by using a mold.

The number of layers of the coating 210 is determined according to actual needs. The coating 210 is a photosensitive resin and a UV resin, and can be formed by ultraviolet curing. Pigments are added to the coating 210 to provide the coating 210 with a desired color. When multiple coatings 210 are used, the color of each coating 210 may or may not be the same. When different colors are selected for each layer of coating 210, the effect of gradient color can be made, so that the color of the coating is closer to the color of a real ear. Each coating layer 210 may be coated on the whole surface of the blank 201 or on a partial surface. When the color of a certain layer of coating 201 is not good or the manufacturing is not ideal, a layer of coating 210 can be coated to cover the coating, so that waste caused by scrapping is avoided. In order to make a more realistic human hand prosthesis 200, blood vessels can be drawn on the surface of the blank 201 or on a certain coating 210, and then the coating 210 is coated to cover the blood vessels, so that the simulation effect is better.
