  1. To achieve the required effect, a lower power is used, the risk of damage to the fiber and its sticking during surgery is reduced.

  2. It becomes possible to perform surgery on a radial fiber with a diameter of 400 microns intended for peripheral veins with a catheter instead of a producer..

Features:

Just like 1470 nm, water is the main chromatophore for a 1940 nm laser. But the energy impact of the latter is tens of times higher, which allows using less energy for a similar clinical effect.

The method of treating varicose veins with the AST 1940 laser is the most modern, effective and low-traumatic. Thanks to the capabilities of laser equipment, they achieve better, in comparison with surgical intervention, results without pain, the use of anesthesia and hospitalization.

Endovenous laser coagulation (EVLK) is carried out using a special Laser for EVLT . In essence, thermal damage to the vein is produced by laser radiation with a wavelength of 1940 nm. At the same time, the lumen of the pathological vein is closed and its subsequent degeneration with the formation of connective tissue. As a result of the operation, the vein is turned off from the pathological blood flow, thereby eliminating pathological reflux.

The operation is performed using a laser for EVLT , as well as a specially developed fiber instrument designed to treat a large area of ​​the venous wall. The results of clinical studies have demonstrated the advantages of the proposed technique in comparison with phlebectomy and radiofrequency ablation, consisting in:

  • high efficiency of the method (complete elimination of varicose veins in 98% of patients);
  • excellent cosmetic result (due to a small puncture when the light guide instrument is inserted);
  • full outpatient treatment (operation within a maximum of 40 minutes);
  • absence of disability;
  • no painful sensations at the end of treatment.
