Abstract
Раскрыто улучшенное средство изоляции электрохирургических инструментов и его использование в электрохирургических инструментах для уменьшения выделения дыма в месте проведения хирургического вмешательства. Применен изоляционный слой, который может включать в себя керамический материал, который, по существу, герметизирован покрытием, образованным, по существу, материалом, основанным на полидиорганосилоксанах или их производных, которое отверждено предпочтительно с помощью температур, превышающих примерно 150°F. В одном объекте изобретения применен изоляционный слой, имеющий теплопроводность примерно 1,2 Вт/смK и силу диэлектрического сопротивления по меньшей мере около 50 В. Такой изоляционный слой предпочтительно может содержать один или более изоляционных материалов с порами, которые герметизированы, чтобы препятствовать попаданию биологических материалов в поры, герметизирующим материалом, предпочтительно содержащим один или более силикатных материалов или материалов, которые образуют силикаты. В другом объекте изобретения обеспечен металлический корпус, имеющий теплопроводность по меньшей мере около 0,35 Вт/смK, и предпочтительно может содержать металл, выбранный из группы: золото, серебро, алюминий, медь, тантал, вольфрам, ниобий и молибден. В еще одном, дополнительном объекте металлический корпус может включать в себя промежуточный слой, который образует периферийный кромочный участок с уменьшенным сечением (например, с толщиной около 0,001 дюйма или меньше) для передачи электрохирургического сигнала. Такой промежуточный слой может содержать металл, имеющий точку плавления по меньшей мере около 2600°F. Средство
