Оптимизировать энергетическое воздействие на венозную стенку при эндовенозной лазерной облитерации (ЭВЛО) радиальным световодом. Материал и методы. Произведено сравнение показателей освещенности моделей насадок на дистальный отдел лазерного световода. Эксперименты выполнены с использованием оригинальных моделей насадок, в корпусах которых были сформированы пустотелые торообразные камеры различной формы, внутренняя поверхность которых была образована по поверхностям Каталана: гиперболе, окружности, двум видам парабол. В качестве контроля использовалась модель известной существующей насадки, т. е. без торообразной камеры. Показатели освещенности моделей насадок снимались люксометром LX1330B в четырех положениях с углом поворота насадок на 90°, 180°, 270° и 360°. Результаты: эксперименты показали, что любая из новых моделей насадок обладает большей излучающей способностью в сравнении с известным прототипом. Модель насадки с параболической формой торообразной камеры обладает наибольшей излучающей, спрямляющей и фокусирующей способностью. Заключение. В результате разработки новой насадки на дистальный отдел лазерного световода, содержащей в своем корпусе пустотелую торообразную камеру, созданы предпосылки для более эффективного энергетического воздействия на венозную стенку в процессе ЭВЛО. Возможность использования нескольких торообразных камер различной формы, обладающих различными линейными плотностями энергии, позволит говорить о новом подходе к реализации ЭВЛО в виде дифференцированного силового воздействия на биологические структуры венозно-кровяного матрикса.</p></abstract><trans-abstract xml:lang="en"><p>Objective. To optimize the energy impact at the venous wall in endovenous laser ablation (EVLA) with a radial fiber. Material and methods. Illumination parameters of various models of headpieces put at the distal part of laser fibers have been compared. Experiments were performed with original models of headpieces which had in-built hollow toroidal chambers of various shapes and the inner surface of which was formed on the Catalan surface: hyperbola, circuit and two kinds of parabolas. As a control, the researchers used a known model of headpiece, i. e. without the toroidal chamber. Illumination parameters of headpieces were measured with luxometer LX1330B in four positions with headpiece rotation angles equal to 90°, 180°, 270° and 360°. Results. The experimental work has shown that any of new headpiece models has better irradiating capacity, if to compare with the famous prototype. A headpiece model with the parabolic shape of toroidal chamber has the best radiating, aligning and focusing capabilities. Conclusion. A new headpiece for the distal part of laser fiber with the hollow toroidal chamber brings better energetic effect at the venous wall during EVLA procedure. Application of several toroidal chambers of various shape with different linear energy densities allows to develop a new approach for EVLA therapy when the differential force effect is applied to biological structures of the venous-blood matrix.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эндовенозная лазерная облитерация</kwd><kwd>насадка на световод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endovenous laser ablation</kwd><kwd>laser fiber headpiece</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ландсберг Г.С.
