A hearing aid 3D eardrum ready for sale
Harvard: There are tens of millions of people around the world whose eardrums have been severely affected by an injury, infection or disease. Scientists at Harvard University have now developed an artificial eardrum, printed with a 3D printer. We will now call it the drum.
We know that there is a thin membrane inside the ear through which sound waves collide, which puts pressure on the screen. The brain processes it and makes it sound to us. If it is damaged, it becomes very difficult to restore the drum. That’s why Harvard experts have created a 3D-printed screen called the Phonograph, which has begun commercial production.
The drum is also called the tamping membrane, which is a very thin and round tissue. Even with a very loud voice, the drum beats and makes a person deaf. Even the effects of bacteria or some other foreign object can destroy it. Infections can also lead to hearing loss.
The traditional treatment is tympanoplasty, in which the eardrum is repaired with the patient’s own skin. But it doesn’t always work. Secondly, in this operation, a small hole is made in the back of the ear and many times the whole operation fails.
To solve these problems, a phonograph has been created that is designed like the wires of a bicycle wheel. It is dipped in polymer ink to give it the shape of a natural airdrum. The patient’s own cells are then implanted, which begin to grow on their own. In this way, the hearing is restored after the transplant. Experimentally, it has been tested on special rats whose ears resemble humans. These experiments have been very successful.
A spin-off company has also been set up for commercial production.
