Стандартные монополярные инструменты несут риски ожогов (0,24 % случаев) и повреждения окружающих тканей (13 % операций) из-за паразитных токов. Для решения этих проблем разработан специализированный L-образный электрод с селективной электроизоляцией и направленным воздействием.Материал и методы. В исследовании описан клинический случай 85-летней пациентки с левосторонним узловым зобом II степени, эутиреозом и первичным гиперпаратиреозом, которой выполнена гемитиреоидэктомия с паратиреоидэктомией с использованием усовершенствованного L-образного монополярного электрода.Результаты и их обсуждение. Новый электрод сочетает изолированную наружную поверхность с токопроводящей внутренней частью и оптимальной 18-сантиметровой длиной, что обеспечивает точное воздействие на ткани, минимизирует риск ожогов гортанного нерва и паращитовидных желез, а также исключает чрезмерное натяжение тканей. Применение электрода у пожилой пациентки подтвердило его эффективность: сохранена нервная функция, достигнут надежный гемостаз с минимальной травматизацией, что соответствует современным стандартам тиреоидной хирургии.Заключение. Разработанный электрод представляет собой значительное достижение в хирургии щитовидной и паращитовидных желез, особенно для сложных случаев и пациентов высокого риска. Внедрение разработки в клиническую практику позволит минимизировать интраоперационные риски и повысить безопасность хирургических вмешательств на данных эндокринных органах.</p></abstract><trans-abstract xml:lang="en"><p>Focal changes in the thyroid gland are detected in 5 % of women and 1 % of men, often requiring surgical intervention. Standard monopolar instruments carry the risk of burns (0.24 % of cases) and damage to surrounding tissues (13 % of operations) due to parasitic currents. To address these issues, a specialized L-shaped electrode with selective electrical insulation and directional effect has been developed.Material and methods. The study describes a clinical case of an 85-year-old patient with a left-sided nodular goiter of grade II, euthyroidism, and primary hyperparathyroidism, who underwent hemitheiroidectomy with parathyroidectomy using an improved L-shaped monopolar electrode.Results and discussion. The new electrode combines an insulated outer surface with a conductive inner part and an optimal 18-centimeter length, which ensures precise tissue exposure, minimizes the risk of laryngeal nerve and parathyroid gland burns, and prevents excessive tissue tension. The use of this electrode in an elderly patient confirmed its effectiveness: nerve function was preserved, and reliable hemostasis was achieved with minimal trauma, which meets modern standards for thyroid surgery.Conclusions. The developed electrode represents a significant advance in thyroid and parathyroid surgery, especially for complex cases and high-risk patients. The implementation of this development in clinical practice will minimize intraoperative risks and increase the safety of surgical interventions on these endocrine organs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>L-образный монополярный электрод</kwd><kwd>узловые образования щитовидной железы</kwd><kwd>гемитиреоидэктомия</kwd><kwd>эффективность</kwd><kwd>безопасность</kwd><kwd>интраоперационные осложнения</kwd><kwd>селективная электроизоляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>L-shaped monopolar electrode</kwd><kwd>thyroid nodules</kwd><kwd>hemitheroidectomy</kwd><kwd>effectiveness</kwd><kwd>safety</kwd><kwd>intraoperative complications</kwd><kwd>selective electrosurgery</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">Haugen B.R., Alexander E.K., Bible K.C., Doherty G.M., Mandel S.J., Nikiforov Y.E., Pacini F., Randolph G.W., Sawka A.M., Schlumberger M., Schuff K.G., Sherman S.I., Sosa J.A., Steward D.L., Tuttle R.M., Wartofsky L. 2015 American thyroid association management guidelines for adult patients with thyroid nodules and differentiated thyroid cancer: The American thyroid association guidelines task force on thyroid nodules and differentiated thyroid cancer.
