Robot and robotechnology news
01.01.1970 //Doctor is robot inside the man.
Nano-robot is created, capable of travelling on the blood vessels at The monreal'skeye university is for the first time in the history created the medical robot, capable of travelling on the blood vessels of the living beings. The assembled with the aid of the nano-technologies ferromagnetic sphere with a diameter of 1,5 mm moved on the artery of experimental pig with a velocity of 10 cm per second. Its motions was sent remotely with the aid of the special computer program. For several years the scientists plan the creation of the nano-robots of even smaller sizes, which can travel inside the human organs, accomplishing micro-surgical operations of unthinkable complexity and fighting with the diseases, which are at present considered incurable. "the application of nano-technologies in medicine find on the initial stage: in the clinics this thus far little adapts, speech, it is faster, it goes about the laboratory experiments, described RBK daily the director of the institute of biomedical technologies Igor artyukhov. - but are the already used in the medical practice nano-devices - in particular, the special capsules, taken orally as the usual medicine: their shell of useyana by the microscopic openings, which make it possible to freely enter inward to the molecules of oxygen and glucose and by at the same time delaying larger objects - the antibody of organism. They can be located inside the capsule, let us say, the cells, which manufacture insulin: sick with the diabetes person, in organism of which are contained such cells, reliably protected from the destructive action of antibodies, can complete a deficiency in this hormone without the aid of injections ". It occurs, nanos-material are capable of playing the role of unique sieve, sifting viruses and bacteria according to so commonplace a sign as their size. "with the aid of the tiny openings, which covered nanos-membrane, cell can be protected from the viruses and even the large molecules, whose entry into the organism we want to avoid, says Mr. Artyukhov. - nanos-particle, with which we work, have several different types. There are organic nanos-particle - liposomes, capable of be incorporated in into the cells, giving to them the specific properties. By metallic nanos-particle it is possible to cover cancerous cell, and then to destroy its, nagrevaya of the microparticle of metal. More complex devices possess a number of the qualities, which can be programmed previously. In the devices, similar to Canadian nano-robot, but which have an even smaller size, it is possible to place tiny video camera and to convert them into the optical probe, which travels on the blood vessels of organism. At present there are nanos-sensor, capable of noting entry into the organism of the specific molecules ". Travelling on the smallest vessels of our organism, nanos-probe are capable of reporting very precise data about the state of our health to doctor. "the possibilities of diagnostics, allowed by nano-devices, are truly extensive, tells IN RBK daily the colleague of center" nano-technologies in electronics "with the Moscow institute of electronic technicians Stanislav Hart. - I can mention the project, which we conducted together with the Belorussian associates, formulation of the diagnosis of disease with respect to a change in the geometry of the motion of the cells of the blood. I will be specified: thus far the majority of the devices of probe microscopy resembles blind with the rod - on the microlevel the light no longer bears so detailed information as on the macrolevel. This is why nano-devices can oshchushchat' blood vessels by practically tactile way, determining the resistance of cloth to action. But the programs of processing their data are completely capable of visualizing information, after showing operator after the computer, as appears one or other cell or another or smallest blood vessel ". "one of the main directions, with which we deal, creation of the biocompatible materials, not torn away by the cells of human organism, or, on the contrary, the materials, which do not make possible to settle on them for bacteria, it described to our publication the colleague of the scientific research institute of the vacuum technique of name S.A. Vekshinskogo Olga zilova. - the first can be used as implantantov (some of them has already been used in the stomatological clinics for the especially complex cases of prosthetics). The second - for creating of medical instruments, packing and the like in any cloth is its own relief its own chemical activity: with the use of usual implantantov and usual tools in some cases can begin an undesirable increase in the cells, in others - on the contrary, their unforeseen extinction. The thorough selection of nanos-material makes it possible to avoid both problems ". Igor artyukhov explains, that on the structure from the biocompatible polymeric nanos-material it is possible to grow separate cloths and entire organs. "special body, the so-called matrix, serves its kind as construction forests, on which the cells are reared, it explains. - very well succeed experiments on the formation of the bone tissue: the osteoblasts multiplied on the matrices make it possible to complete the defects of the bone, and to also create the "glue" for the bones, which helps to grow together the damaged extremities. Experiments on the cultivation of nerve tissue are much more complex - however here there are the successes: at present, for example, are conducted experiments on the carbonic tubes on the repair of spinal cord ". The biocompatible materials make it possible to integrate living tissues and electronics into the united system. At the end of the past year for the scientists Of the portsmutskeyeo university it was possible to develop the first bioelektronnyy switch on the basis of the molecules OF DNA: device makes it possible to connect the living nerve of the damaged extremity with the electronic sensor of the controlled prosthesis with size into one thousandth of the thickness of human hair. The nano-technologies and the micro-surgery will be derived on the radically new level - microscopic robots working inside the eyeball can return to patient sight, and those being taking root directly in the brain of nano-device can fight with its tumors, and also with the psychic illnesses, which have somatical soil. "regulating force and speed of the motion of sensor, it is possible to attain mechanical action on the cells and the separate molecules, says Stanislav Hart. - are already developed the chemical methods of action with the aid of the nano-devices - local anodic oxidation of the molecules of cell, for example ". Accurately governing the displacement of capsule with the medicine, operator will be able to reach medicines directly into the struck organs. "Canadian nano-robot - prototype of the more advanced controlled devices, capable of being moved inside different organs, killing atherosclerotic platelets and cancerous cells, and to also carry out the most complex micro-surgical operations, notes Igor artyukhov. - nano-revolution in medicine, it goes without saying, will occur not within the next few years, but I is confident, that years through 10 - 20 devices, about which I spoke, they will become completely everyday reality ".
