Finger Prostheses
On Habré already mentioned prosthesis for people who have completely lost the brush. But the company-developer ( Touch Bionics ) does not stop there. People who have lost their fingers can now replace them with a robotic prosthesis .
')
Not all missing finger configurations are available for prosthetics: there are restrictions on the use of the new prosthesis. The ideal candidate for the installation of mechanical fingers are those who lack all fingers, i.e. to the metacarpal bone . The company consults with prosthetists for the best use of the prosthesis.
The device requires batteries and the possibility of their setting, as well as devices for switching on / off the prosthesis. The location of these elements depends on the length of the damaged limb. In any case, each time they select a position individually.
The prosthesis is controlled by myoelectrodes or resistance elements with pressure sensitivity. Sensors are attached to the skin and react to muscle contraction. These cuts are filtered, amplified and sent to a device that drives mechanical fingers.
