COMBINED INSTRUMENT FOR ENDOVASAL LASER OBLITERATION OF VEINS

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medical equipment. Instrument for the treatment of varicose veins by the method of endovasal laser obliteration (EVLO) of veins contains a body in which an inner chamber is made in the form of a torus-like shape spatial figure. Toroidal chamber inner surface is a part of the Catalan surface, formed by the second-order curve rotation around the light guide long axis with possibility of the laser radiation focusing into the radial annular flow. Chamber is isolated from the bloodstream in the vein by a lens-shaped lid. Light guide distal end is formed as a polyhedral truncated pyramid and is located in the nozzle central chamber.;EFFECT: instrument has increased reliability.;1 cl, 3 dwg
