Abstract
Изобретение относитс к медицинской технике, а именно к управл емым эндоскопам. Предложенна конструкци гибкой управл емой трубки позвол ет получить необходимую свободу движени в четырех направлени х - вверх-вниз-вправо-влево при одновременном уменьшении диаметра до 2 мм и менее. Трубка состоит из одинаковых шарнирно соединенных элементов и четырех тросиков 2. Каждый элемент представл ет собой тело, ограниченное двум цилиндрическими поверхност ми и вдоль оси шарнира /внутренней 3 и наружной 4 соответственно/ и двум цилиндрическими поверхност ми 5 и 6 с торцов /выпуклой и вогнутой соответственно/ так, что оси вращени этих двух поверхностей повернуты на 90° относительно одна другой, и двум лысками, перпендикул рными поверхности 4 и не пересекающими поверхность 3. Внутренн поверхность 3 имеет две канавки, параллельные продольной оси шарнира, расположенные диаметрально в плоскости, параллельной плоскост м лысок. 4 ил.The invention relates to medical technology, namely to controlled endoscopes. The proposed construction of a flexible controllable tube allows obtaining the necessary freedom of movement in four directions - up-down-right-left while reducing the diameter to 2 mm or less. The tube consists of identical hinged elements and four cables 2. Each element is a body bounded by two cylindrical surfaces and along the axis of the hinge (inner 3 and outer 4, respectively) and two cylindrical surfaces 5 and 6 from the ends / convex and concave respectively / so that the axes of rotation of these two surfaces are rotated 90 ° relative to one another, and with two flats, perpendicular to surface 4 and not intersecting surface 3. Internal surface 3 has two grooves parallel The longitudinal axis of the hinge is diametrically located in a plane parallel to the planes of the faces. 4 il.
