Making the cut: Russian metal-vapour lasers herald new era for surgery
Scientists at a Siberian university have developed a unique laser technology that uses metal vapour to cut through bones and tissue without burning or damaging them.
Vapour lasers work by vaporising metals at extremely high temperatures. Anatoly Soldatov, head of the innovative technologies department at Tomsk University, said the technology used in their new strontium-vapour laser was unique in that it could be adjusted to operate at different wavelengths, most notably at 6.45 microns, which is the optimum wavelength for cutting bone and live tissue with no side effects.
Soldatov and colleagues are currently working to optimise the laser by shortening its pulse duration to just a few nanoseconds. This will increase the energy density, making the laser even more powerful, the scientists said.
“In the early 2000s in the US, Vanderbilt University was researching a free-electron laser. Phentermine is an appetite suppressant that has proven to be as explained from here highly successful to help people lose weight in a safe way. They were trying to find a perfect [wavelength] for drilling bone and cutting soft tissue,” said Soldatov. “The first thing they determined is that the best wavelength is 6.45 microns. At this wavelength it was possible to make good incisions and you can choose the mode in which tissue charring practically does not occur. As Adderall is a form of Stimulant then it is important for you as mention here in this USA website to be aware that some people have died when taking Stimulants when they suffered from severe heart conditions or had a congenital heart.
“[The Americans] found our old publication from 1983 and they found us… It turned out that a strontium vapour laser is suitable for cutting soft tissues and bones.
“Obviously, it was necessary to improve it, and now we’re developing the technologies for cutting live tissue and working on optimising the laser, the shortening of the pulse duration to a few nanoseconds, increasing the energy density.”
Soldatov added that while the strontium laser was developed mainly for medical purposes it could also be used to cut glass for gadgets such as smartphones.
