METHOD OF LASER TREATMENT OF SURFACE LOCATED VASCULAR AND NEUROPLASTIC FORMATIONS Russian patent published in 2018 - IPC A61B18/20 A61N5/67 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to ophthalmology, cosmetology, maxillofacial and plastic surgery, and can be used to treat bulk superficially located vascular and neuroplastic formations. Formations are irradiated using invasive action by introducing a neodymium (Nd:YAG) laser into pathologically changed tissue. In addition, a low-intensity helium-neon laser (HNL) is used. Two kinds of laser energy of a diversified purpose from Nd:YAG laser and HNL are conducted through a single laser light guide of 450 ± 10 microns, made of optical quartz fiber and also performing the function of a probe to enter the tissue. Light guide is inserted perpendicularly into the perifocal tissues of the patient, retreating 2–5 mm from the formation boundary to a depth of 5–10 mm. Then the light guide is unfolded by 90 degrees and is led in parallel with skin formation. Moving the light guide inside the formation throughout its volume, an interstitial pulsed high-energy photocoagulating effect of Nd:YAG with a laser with a wavelength of 1.44 mcm, energy of 60–120 mJ, a pulse repetition rate of 10–20 Hz, a pulse duration of 50–80 mcs is carried out. Formation is irradiated under visual control of the position of the working end of the fiber, guided by the red glow of the HNL radiation, operating continuously in a continuous mode. Wavelength 0.63 mcm, power from 2 to 10 mW. At the same time, HNL has a phototherapeutic and biostimulating effect on tissues. Photocoagulant effect is carried out until the abnormalities of the pathologically altered tissues of the formation are whitened.

EFFECT: method ensures the precision of laser action, reduces the risk of thermal damage to biological tissues and traumatism.
