Engineers from Sechenov University, NRU MIET and OKB Bulat have developed a laser complex that will allow bloodless wound closure operations without tissue burns and scar formation.
During an operation using a new technology, solder is applied to the laser-affected wound area – a special protein composition containing nanoparticles.
It is important that the latter does not burn and solder the wound, says Alexander Gerasimenko, one of the developers, head of the laboratory for biomedical nanotechnologies at the Institute of Bionic Technologies and Engineering at Sechenov University.
The heating control system developed for this purpose allows you to determine the exact range according to the type of fabric and maintain it throughout the entire operation with an accuracy of 1 °C. The radiation power is adjusted according to the “hottest” point of the seam.
As a result, a neat and almost imperceptible suture is formed at the incision site. Ten days after the operation, the skin is completely restored and there is no scar in the wound area.
With the help of a new laser device, operations are already being performed on laboratory animals. The scope of its potential application is wide: the laser can be used in plastic and classical surgery, in the restoration of cartilage, ligaments and tendons, as well as in the reconstruction of organs of the cardiovascular system.
