It is possible to create better eyelids than ever with 3D printers

Ear is a complex part in the body and it is a very difficult part to duplicate,gunYadressIt is possible to duplicate your ear easily by using a 3D printer which can be created even with complicated structures. According to Associate Professor Lawrence Bonazar of Kernel University, if you make an eyelid based on the ear copied with a 3D printer, it can be one of new treatment for patients who have broken or lost their ears due to illness or accident It is said that there is sex.

until nowMicrotiaAnd treatment methods for those who have lost a part or all of their ears due to accidents or other "StyrofoamThere are two kinds of methods of shaping and transplanting the right ears from the material such as "the method of creating and transplanting the prosthetic limb using the costal cartilage from the patient's rib". However, the treatment method of making prosthetic ears from costal cartilage is accompanied by severe pain with a high degree of difficulty, it is incomplete in shape compared with real ears, there is a possibility that it will not function properly, etc. with risks did.

According to Associate Professor Bonazar, if you use a method to create an eyelin with a 3D printer, a patient whose only ear is suffering from or is damaged by small ears, can make a copy with a 3D printer using the other ear as a model , Patients without both ears can create models from people's ears that are similar. Because I do not use my own cartilage, I have less pain, and there seems to be advantages such that the shape does not collapse after surgery.


Procedure to create the prosthesis, first scan the ears that are models of the prosthesis ... ...


We will import it into the PC as image data.


This is the state of the image data of the ear being read in the personal computer.


Then, output the image data with the 3D printer, and create the type of the prosthesis. It took about one and a half days to complete this work.


Next, collagen taken from the mouse's tail and 2.5 million cartilage tissues extracted from the ears of the cow are poured into the completed mold. Unlike popular ears, using living cells allows the growth of righteous ears along with the growth of patients, so they can be transplanted to children born by inborn ears.


Here are the right ears you took out in about 15 minutes. You can transplant this small prosthetic ear directly to the patient.


If the prosthetic limb is too small to fit the patient, it feels a bit strange, but it is also possible to transplant the resulting right ear after growing for 1 to 3 months on the rat's back. By the way, the image is not where the right ears are actually growing.


According to Spector Doctor, if this right-ear is approved as safe, it can be realized as a new treatment within 3 years. Furthermore, in the future it is currently under investigation of a new method in order to make it possible to use human cartilage tissue instead of cattle.
