Leg prostheses - high-tech devices

The modern field of prosthetics is developing at a rapid pace, which makes it possible to raise the standard of living of people who, for certain reasons, have lost limbs.

На сегодняшний день протезы ног становятся high-tech devices. An important breakthrough in prosthetics was biomechatronics. With its help, new-generation bioelectric prostheses were manufactured. They register electrical signals while reducing the muscles of the injured limb, which allows for a wide variety of movements. However, their functionality may even exceed the possibility of healthy legs.

Some of them can be programmed onseparate movements. In addition, prosthetic legs may have a special silicone coating that perfectly masks the defect, which helps to hide the absence of a limb and reduce unwanted attention from surrounding people.

The last achievement in the field of prosthetics -osteointegration (implantation of the prosthesis into the bone). This technique can significantly reduce the rubbing or injuries of the stump, as well as fully control the artificial limb. Such prosthetic legs in the places of exit from the bone tissue are covered with a special material that not only imitates the presence of tissue, but also perfectly protects against the ingress of various infections.

The most popular prostheses for the lower extremities are models with electric motors. They are characterized by a hydraulic drive, include a microprocessor and special software.

These prosthetic legs began to be produced in 1997,but already managed to become classics. They are more functional than mechanical models, have three modes of operation, as well as remote control. This allows a person to forget about the artificiality of his legs, because it allows not only to walk, but also to climb stairs or ride a bike.

В 2006 году был создан электронный модуль с artificial intelligence. Due to the efficient operation of sensors and microprocessors, it takes into account the peculiarities of a person’s gait, as well as regulates the level of fluid in the artificial joint, which allows for extra comfort when moving the body.

It is worth noting that the key problem withthe development of artificial limbs was the creation of an optimal point of support relative to the full functioning of the foot. Modern prostheses for the legs are designed with this in mind. So, they are equipped with complex hydraulic systems that imitate the position of the foot when walking, standing or running.

I must say that high-quality prostheticsnecessary for effective restoration of motor and support function of a lost limb. Prosthetic legs, the price of which varies widely, can avoid many problems, including helping to maintain balance. In addition, modern artificial limbs make it possible not only to walk, but also to run, mountaineering, surfing, skiing or skating, so it can be argued that there are only insufficiently effective prosthetic technologies, not people with disabilities.
