In Russia, about seven thousand people need prosthetic hands.
In order to lead a full life, them need the most perfect solutions in this area.
These solutions are high-tech bionic prostheses, controlled by bioelectric signals of the user's muscles.
However, the cost of advanced prostheses is more than 30 thousand dollars, and inexpensive bionic prostheses allow you to perform only one gripper and become morally obsolete.
This situation is exacerbated for cases of congenital defects or partial amputations of the hand, as well as for bionic prosthetics of children.
Next, we will talk about how the prosthesis SmartLi combines the latest advances in prosthetic hands and allows you to achieve the maximum rehabilitation effect during use.
Prosthesis SmartLi has a modular design and is applicable for any case of amputation or congenital malformation of the hand for both adults and school-age children.
The use of standardized elements allows improve the unification of production, reduce the cost of the prosthesis and the time of its manufacture.
SmartLi adult prostheses have a unique finger design with their division into three phalanges and the ability to choose the degree to which the thumb is brought to the palm of the prosthesis, and the children's versions, unlike those on the market, are equipped with three separate blocks I, II-III and IV-V fingers.
The driving system of all versions of the prosthesis allow in less than two seconds to perform a grab with a force of up to 5 kilograms.
The prosthesis is equipped with a capacious lithium iron phosphate battery resistant to cold and inflammation.
The SmartLi prosthesis is a smart prosthesis. It has a modern controller, finger position sensors, pressure force sensors on the surface of the held object.
For the first time in Russia, the prosthesis uses a neural network with the ability to learn and recognize gestures to switch grippers patterns and settings.
The prosthesis can be controlled both with the help of wired sensitive electrodes and with the help of the of a wireless bracelet. Feedback from the user is carried out tactilely with the help of vibration feedback.
Within the concept of the Internet of Things (IoT), the prosthesis can interact with the wireless bracelet and mobile devices.
SmartLi prosthesis uses reliable and safe materials, such as medical plastics, elastomers.
For the manufacture of the mounting base of adult prostheses used carbon fabrics, which reduces the total weight of the prosthesis and increases its strength.
The same alloys used in the aviation industry are used to manufacture the parts of the prosthesis; carbon fabrics are used to make the frame elements of adult prostheses.
All this makes the Smartli prosthesis light weight and reliable.
A large part of the usability of the prosthesis depends on how the cult-receiving device is made.
In SmartLi prostheses, the manufacture of a cult-receiving device is made out only at an individual plaster cast of the consumer’s limb, which makes it possible to make it as comfortable as possible in everyday use..
The сult-receiving device can be made from cast polyethylene, or using composite materials such as aramid or carbon fabric or their mix.
In prostheses for cases of partial amputation of the hand, the сult-receiving device is made of a durable and flexible elastomer.
