Scientists from China have presented a robot printer that can be inserted into the human body, where the device will produce new tissues. So you can cure stomach ulcers and other diseases, and this does not require large-scale surgical intervention.
The researchers explained that stomach ulcers and other organ damage occurs in one in eight people worldwide, and conventional treatments have their drawbacks. Scientists want to solve this problem using 3D printing, where living cells are immediately placed in the human body.
According to their idea, bioprinters produce living cells for the formation of tissues and organs. In order to avoid surgeries, the printer is inserted into the patient’s body through small incisions, which form new tissues within a few months. Then the devices dissolve. Scientists note that in this way they can even influence infertility.
In the future, this technology may be able to help people who are on the waiting list for organ transplants. True, scientists will have to refine this method, but they can already produce simpler structures. They do not require surgery, which carries a high risk of infections and a long recovery period for the patient.
The micro-robot the scientists use is only 30mm wide, about half the width of a standard debit card, and folds up to 43mm long. Once inside the patient’s body, it unfolds to 59 millimeters and begins bioprinting. “The team has designed clever mechanisms that make the system compact when entering the body, but the device can be deployed on site for comfortable typing,” said David Hoells, a mechanical engineer at Ohio State University.
Researchers looked at previous work in bioprinting, but noticed that most of it focused on healing the skin and other external tissues of the body. However, the new device, due to its size, allows access to the gastrointestinal tract and other organs, and without extensive surgical interventions.
In another experiment, scientists in China wanted to develop a miniature robot bioprinter that could penetrate the human body with relative ease. Researchers have tried to create a semblance of miniature bees, but have not yet completed their development.
