Abstract

FIELD: medicine, noninvasive surgery for treatment of inner organs oncologic diseases, that have low capability to absorb energy of ultrasonic oscillations, for example, thyroid gland. SUBSTANCE: apparatus has piezoelectric focusing ultrasonic emitter connected to output of ultrasonic frequency alternating voltage oscillator and made with concave surface, that touches working liquid in container, that has bottom made in the form of member touching skin of patient. Piezomember of focusing emitter is made with variable thickness with maintaining constant focus distance. In the case maximum thickness of piezomember of focusing emitter in respect to its minimum thickness is in limits of 1.01 - 1.15 and alternating voltage frequency incited by oscillator is changing during incitation so, that its maximum value ratio to its minimum value is in the dame limits. EFFECT: expanded capability to increase ultrasonic energy dose required for final destruction in strictly limited margins of oncologically affected areas of biological tissue with low effect of the energy absorption without inflicting damage to sound tissue.

Изобретение относится к медицинской технике, в частности к устройствам для хирургии, и может найти применение при неинвазивной хирургии в случае онкологических заболеваний внутренних органов, обладающих малой эффективностью поглощения энергии ультразвуковых колебаний, например, щитовидной железы и др. Технический результат выражается в расширении возможности повышения дозы ультразвуковой энергии, необходимой для необратимого преобразования (разрушения) в строго локализованных пределах онкологически пораженных участков биологической ткани со слабым эффектом ее поглощения, без повреждения прилегающей здоровой ткани, в том числе и обладающей существенно большей эффективностью поглощения энергии ультразвука. Для получения этого технического результата в устройстве для воздействия ультразвуком на внутренние участки организма человека содержится пьезоэлектрический фокусирующий излучатель ультразвука, подключенный к выходу генератора переменного напряжения ультразвуковой частоты и выполненный с вогнутой поверхностью, соприкасающейся с рабочей жидкостью, находящейся в контейнере, имеющем дно в виде элемента соприкосновения с кожей человека, пьезоэлемент фокусирующего излучателя выполнен с переменной толщиной при сохранении неизменного фокусного расстояния, причем максимальная толщина пьезоэлемента фокусирующего излучателя относится к его минимальной толщине в пределах 1,01 - 1,15, а частота переменного напряжения, возбуждаемого генератором, изменяется за время возбуждения так, чтобы ее максимальное значение относилось к минимальному в тех же пределах.The invention relates to medical equipment, in particular to devices for surgery, and can find application in non-invasive surgery in the case of cancer of the internal organs with low efficiency of absorption of energy of ultrasonic vibrations, for example, the thyroid gland, etc. The technical result is expressed in expanding the possibility of increasing the dose ultrasonic energy necessary for irreversible transformation (destruction) in strictly localized limits of oncologically affected areas of biologically Coy cloth with a weak effect its absorption, without damaging the surrounding healthy tissue, including having a much greater absorption of ultrasound energy efficiency. To obtain this technical result, the device for ultrasonic exposure to the internal parts of the human body contains a piezoelectric focusing ultrasound emitter connected to the output of the ultrasonic frequency alternating voltage generator and made with a concave surface in contact with the working fluid located in the container having a bottom in the form of a contact element with human skin, the piezoelectric element of the focusing emitter is made with a variable thickness while maintaining unchanged the focal distance, the maximum thickness of the piezoelectric element of the focusing emitter relates to its minimum thickness in the range 1.01 - 1.15, and the frequency of the alternating voltage excited generator excitation varies over time so that its maximum value refers to the minimum in the same range.
