The innovative artificial hands were created by a team of scientists from the Medical University of Vienna.
According to them, the bionic hands are controlled by using the muscles and nerves transplanted from the men’s legs into their arms.
Dr. Oskar Aszmann, one of the researchers involved in the new project, explained that this is the first time anyone has ever constructed a hand using bionic technology.
Dr. Oskar Aszmann said that this would not have been possible five to seven years ago, and if there would have been similar cases of limb amputation back then, the doctors wouldn’t have been able to help the patients.
Dr. Oskar Aszmann is a scientist at the Medical University of Vienna.
The three men volunteered to take part in the experiment, which involved having the lower parts of their injured arms amputated. Then they had to learn how to use faint signals transmitted from the transplanted muscles and nerves to use the bionic hands.
One of the men lost his arms in a traffic accident, another injured himself while climbing and the third man, Milorad Marinkovic, 30, lost the ability to use his right hand after being involved in a motorbike acceded more than ten years ago.
Marinkovic has two kids, a boy and a girl, and they used to hold their father’s hand one by one. Thanks to the new bionic hands, both children can hold their father’s hands at the same time.
Dr. Aidan Roche, one of the scientists involved in the bionic hand implants, explained that training the men before and after the implant was the hardest thing.
The men had to recover for several months in order for the muscle transplant to integrate into their body. After that the men had to learn how to twitch the muscles in order to change an image on the computer.
As soon as they managed to control the muscles, the doctors amputated the hands and the new bionic hands were attached.
