Description
Известны стоматологические диатермокоагул торы , содержащие силовой трансформатор , выпр митель на полупроводниковых диодах , сглаживающий фильтр и фильтр пациента дл подавлени помех радиоприему, держатель инструментов, набор режущих и коагулирующих инструментов. Указанные диатермокоагул торы имеют два электрода - активный и пассивный. Применение пассивного электрода не исключает, например, болезненных ощущений пациента в области наложени пассивного электрода, ожогов, возможности поражени током пациента и обслуживающего персонала .
В предлагаемом диатермокоагул торе используют электрическую схему, котора не требует применени «пассивного электрода. -Така схема содержит, например, автогенератор , выполне 1ный по схеме кварцевого автогенератора с электронной св зью при включении кварца между экранирующей и управл ющей сетками лампы.
Дл предотвращени расстройки контура при нагрузке в аппарате включен параллельный контур, настроенный на основную частоту генерации.
струмента на диатермокоагул торе установлен манипул тор.
На чертеже изображена электрическа схема предлагаемого диатермокоагул тора.
Аппарат содержит автогенератор /, выходное устройство 2, блок питани 3. Автогенератор / выполнен по схеме кварцевого автогенератора с электронной св зью при включении кварца 4 экранирующей и управл ющей сетками генераторной лампы 5.
В качестве выходного устройства в схеме используетс параллельный контур, который образуетс индуктивностью 6 и конденсаторами 7 и 5. Конденсатор 7 вл етс конденсатором настройки контура на основную частоту генерации. Конденсатор 8 служит конденсатором св зи с пациентом, который не допускает расстройки контура при присоединении аппарата к пациенту. Поскольку параллельный контур хорощо фильтрует высщие гармоники, он используетс как фильтр пациента. Дл предотвращени попадани посто нной составл ющей в цепь пациента и травмировани его током в схеме аппарата предусмотрен дроссель 9. Роль регул тора мощности в схеме аппарата выполн ет потенциометр 10, включенный в цень экранирующей сетки лампы 5.
водниковых диодах, сглаживающий фильтр, выполненный по однозвенной схеме на конденсаторе 13 и сопротивлении 14. Дл подавлени помех радиоприему в аппарате примен етс фильтр, который состоит из фильтра пациента - выходного устройства 2 - и сетевого фильтра, выполненного на конденсаторах 15 и }6 н использующего экранную обмотку силового трансформатора 11.
В качестве держател инструментов используетс манипул тор с кнопочным включателем 17, расположенным в ручке манипул тора. Кнопочный включатель служит дл включени и выключени в нужный момент высокочастотного пол на режущем или коагулирующем инструменте. Вкл е;ь5нный в цепь пациента кнопочный включатель выполн етс с малой междуконтактной /емкостью, что предотвращает проникновение даже малых доз тока высокой частоты па инструмент при разомкнутой цепи.
