Russia has developed a medical laser, which has no analogues in the world

Specialists from the Tomsk State University presented their new innovative design – laser cutting of biological tissue and bone. Development has no analogues not only in Russia but also worldwide. The main new feature of the laser apparatus is that the charring of tissue under the influence of the laser does not occur. At the site of the impact beam – only a small incision and a thin film with a thickness of only a few microns.

The authorship of the invention by Professor Anatoly Soldatov, who said that the main difficulty was that the limit of the heating temperature in the case of living tissues – 45 degrees Celsius. At 100 degrees charming and death of tissue. Therefore, the developers had a task to find a long war that is optimally suitable for work with such material.

Tomsk scientists relied on the development of their colleagues from Vanderbilt University, who had previously failed to establish that the best option – infrared radiation with a wavelength of 6.45 microns. But the main disadvantage is bulky laser setup. Russian scientists were able to solve this problem: their installation is placed on a normal desk

Russian Position feedback feature is that any live tissue contains moisture, and even if short-exposure infrared rays with a wavelength of 6.45 microns there is practically instantaneous heating of water vapor with simultaneous sudden increase in pressure. This process ends break molecular bonds, reducing to a minimum temperature of a “living” tissue during laser exposure.

Russian plant can operate at different wavelengths, it opens up tremendous opportunities physicians. Today made using laser surgery to remove the trial of varicose veins deserved only positive reviews. Currently being tested a new method of the participation of experts of one of the capital’s universities. Today it is known that the new setting can be used in the treatment of oncological diseases and in implantology.
