In recent years, scientists have developed various mechanisms and techniques for smart prosthetics, but most of them were limited movements.
But the new artificial hand, developed by scientists at Chalmers University of Technology in Sweden, simulates the real hand almost completely and has been planted instead of a limb, according to Digital Journal.
The implant was performed in Sweden for one of the patients in the amputated hand: a titanium organ graft was inserted between the two bones of the joint and electrodes were installed for nerves and muscles to extract signals designed to control the mechanical hand and allow tactile sensation.
This implant is the first artificial hand in the world to function efficiently and competently and can be used normally.
The first parts suffered from a relative weakness of movements and sensations, because they required the installation of electrodes on the skin to extract the control signals from the main muscles of the trunk. These electrodes can only provide a limited number of signals. These signals allow the user to perform simple operations like open and close the hand. Only
But in this new hand, researchers have been able to provide more reliable information to implant muscle electrodes with a greater variety of movements, by connecting the poles to biological sensors allowing the patient to control the hand. artificial as he did with the natural hand.
The patient is currently undergoing a rehabilitation program to restore the strength of both forearm bones so that she can carry the artificial hand.
"The breakthrough in our technology depends on patients' ability to use the neural and musculoskeletal interfaces to control their prostheses, while recognizing the sensations they are concerned about in their daily lives," said the team leader. , Ortiz Catalan.
