Полная стерилизация инструментов, используемых роботом-хирургом, невозможна
Специалисты из Университетской больницы Токио (University of Tokyo Hospital) пришли к выводу, что даже после многократной очистки инструменты, используемые роботом-хирургом для проведения операции, не становятся абсолютно стерильными. Их невозможно полностью очистить от загрязнителей, несмотря на соблюдение всех рекомендаций производителя. Это значит, что существует риск инфицирования пациентов во время проведения операции. Полученные авторами данные были опубликованы в Infection Control & Hospital Epidemiology в октябре 2016.
Авторы изучали стерильность хирургических инструментов — они определили уровень загрязнения на поверхности 132 предметов, среди которых были как обычные хирургические принадлежности, так и предназначенные для робота. Для очистки принадлежностей применялись рекомендованные производителями методы, включая и ультразвуковой. Все исследуемые инструменты были изъяты сразу после использования и простерилизованы трижды. Роботизированные принадлежности были очищены на 97,6 %, а обычные инструменты — на 99,1 %. Меньшая степень очистки оказалась связана с более сложной структурой режущих поверхностей инструментов, используемых роботом, — они сильнее загрязнялись и полностью очистить их было сложнее.
Юшеи Саито (Yuhei Saito) и другие члены исследовательской группы считают, что необходимо разработать новые стандарты как для стерилизации предназначенных для роботов инструментов, так и для оценки их чистоты.
