Penal holes in the eardrum led to pain and hearing loss, and could be difficult to recover as originally. However, phonograft, developed by Harvard scientists, is a 3D print implant that can patch lesions by promoting natural cells and it has been put into commercial production .0: 00/2: 15 Southern Nortal Area is a thin tissue piece, circle, vibration to react with sound waves and convert them into electrical signals that the brain can explain. But it can't do it well if it is punctured by strange objects like cotton heads or are loudly loud. Worse, with that barrier, viruses and bacteria can penetrate into the inner ears and cause serious infections
. Currently, the best treatment is called atrial pattern surgery, including Fix the hole by using the patient's own tissue. But the end result does not lead the sound as well as a healthy eardrums, this process requires the following incision after the ear, and it can often fail and need to be done again .Phonograft is a new implant device possible 3D printing to repair
Phonograft is designed to solve those problems. The implant simulates the complex shape of natural tumper, with "spokes" patterns like bicycle wheels and it is made of specially developed synthetic polymer ink for 3D printing. The implant device itself does not only have a hearing recovery effect but also provides support for cells of the recipients itself. Trials in Chinchillas - Animals structured with ear surgery and hearing scope are similar to humans, have been proven to be promising. The Aaron Remenschneider - a project researcher said: "Three Month after our optimum transplant into Chinchilla's ears, we had a really great moment. Hearing tests show that the ability to transmit sound transmission is completely restored. After that, we looked down at the ears with endoscopic tubes, what we found merely the shadow of the puzzle piece are being replaced with a new tissue - a beautiful tissue membrane with round-shaped patterns Its mind ". Besides, phonograft can be taken through the ear tube, which helps this process less invasive. To bring the device to the market, Harvard's WYSS Institute has established a startup company named Beacon Bio, this company has recently been acquired by the Desktop Health - a step to help it be ready to bring to the market. The team is currently working to obtain the FDA license to bring the phonograft to the patient
Other similar implant devices are also underway, such as Cleardrum in Australia. . Dịch vụ:
