To print the 3-D printer “parts” to replace damaged limbs began Russian scientists. Unlike previous prosthetics, which only served a cosmetic function, of new implants and make up for the lack of movement. The first limb, printed on a 3-D printer, while not having analogues in the world, implanted a laboratory rabbit in Kurgan scientists of the Russian scientific center named. G. A. Ilizarov. The details of this latest technology found out “MK” talked to the head of the center Alexander GUBIN.
– To our new technology, if necessary, the installation of prosthetic limbs, the doctors fastened the artificial part to the cult – the rest of the limb straps and a special sleeve. To fully walk in this patient was difficult, – says Alexander Vadimovich. – However, there were many cases in the removal of a limb or amputation, when we were forced to refuse patients in the prosthesis. The obstacle was the remaining non-standard small bone fragments that a standard denture generally could not be installed. To solve the problem helped the technology of 3-D printing.
According to the head of the center, made of titanium powder the printer to create a small product is shaped to mimic the patient’s stump and screwed it on the principle of a screw. And then this “screw” that continues the bone, you can wear any prosthesis. Design, first, is very strong, and secondly, in addition to the role of beauty also has a functional value since 3-D part is an implant, a person can move it, and therefore put on her prosthesis. Recently, the experts tested the new technology on a rabbit who lost a foot.
– In the queue now volunteers – people who have lost phalanges fingers, ” says Gubin. We have done everything to make them the most advanced to date implants. Their artificial fingers, due to the fact that we partially implant them in the bone will move like the real thing.
This technology is now being developed in Sweden, Australia and the USA. But I hope that the priority of the prosthetic finger will be for Russia. In the future, the researchers plan to “grow” human fragments of arms, legs and even skulls.
There is a breakthrough in scientists and in the other direction of activities relating to stretching of the bone tissue. Through the development of special software, they can do it now… in the distance. Previously the patient it is only necessary to install automatic compression-distraction medical device, which myself with the help of micromotor and the program gradually expands the bone. The patient can then leave from the clinic even to the other end of the world, the doctor is still using the computer can control the process and to give necessary recommendations. For reference, the maximum tapisciaceae stretching of a limb to date is 52 cm.Related posts:
