Abstract
Изобретение относится к медицине, к разделу эндоваскулярной хирургии и позволяет увеличить амплитуду продольных колебаний рабочей головки, а также повысить надежность в эксплуатации за счет плавного изменения напряжения по всей длине волновода благодаря тому, что волновод выполнен в виде стержня переменного сечения с последовательным уменьшением диаметра между проксимальной, средней и дистальной частями, при этом диаметр рабочей головки больше диаметра дистальной части в 1,5 раза. Способ изготовления волновода позволяет путем плазменной электролитной обработки цилиндрического стержня-заготовки получить заданные конические переходы типа концентратора Фурье между проксимальной, средней и дистальной частями за счет того, что заготовку помещают в электролит под углом от 0 до 90° по отношению к плоскости электролита, после чего заготовке задают вращение вокруг продольной оси, затем осуществляют ее перемещение из электролита вдоль продольной оси, а для создания конического перехода по типу концентратора Фурье на меньший диаметр заготовку перемещают из электролита вдоль ее продольной оси с шагом перемещения 1 мм согласно значениям величины перемещения и получения диаметра.The invention relates to medicine, to the section of endovascular surgery and allows you to increase the amplitude of the longitudinal oscillations of the working head, as well as to increase reliability in operation due to the smooth voltage change along the entire length of the waveguide due to the fact that the waveguide is made in the form of a rod of variable cross section with a proximal diameter reduction , middle and distal parts, while the diameter of the working head is 1.5 times the diameter of the distal part. The method of manufacturing a waveguide allows, by plasma electrolytic processing of a cylindrical billet, to obtain predetermined conical transitions of the Fourier concentrator type between the proximal, middle and distal parts due to the fact that the workpiece is placed in the electrolyte at an angle from 0 to 90 ° with respect to the electrolyte plane, after which the workpiece is set to rotate around the longitudinal axis, then it is moved from the electrolyte along the longitudinal axis, and to create a conical transition like a Fourier concentrator The diameter of the workpiece is moved from the electrolyte along its longitudinal axis with a displacement step of 1 mm according to the values of the displacement and obtaining the diameter.
