Description

 The invention relates to physiotherapy, is intended for locally-selective therapeutic effects of low-intensity millimeter-wave (EHF) electromagnetic radiation on the cellular tissues of living organisms and can be used in reflexology to stimulate biologically active points, in ophthalmology to accelerate healing processes after microsurgical exposure and for local iridotherapy, as well as in otolaryngology, cardiology, gastroenterology, gynecology, urology and oncology for vital processes in living tissues both on the surface and in the inaccessible internal cavities of a living organism.

 A device for therapeutic effects [1], containing a laser and a fiber waveguide. The disadvantage of this device is the impossibility of resonant stimulation of the cellular tissues of living organisms in the EHF range, which reduces the effectiveness of therapeutic effects at the cellular level.

 The closest solution to the present invention is a therapeutic effect device designed for low-intensity microwave exposure to the cellular tissues of living organisms and containing a microwave generator and a waveguide transmission line [2]. The disadvantage of this device is the low efficiency of the process of restoring the vital activity of biological tissue at the cellular level, as well as the large mass, dimensions and limited functionality of the device.

 The aim of the invention is to increase ease of use and the ability to individually select the frequency of exposure.

 The goal is achieved by adding 5 lens focusers, an optical Y-splitter and a Y-adder defining a single-mode laser, two synchronized single-mode lasers, a laser pump source, a frequency control and stabilization microprocessor and two thermocouples, and a waveguide transmission line in the form of an optical fiber with N optical couplers (N = 0,1, ...) uniformly spaced along the length of the optical fiber, with N focusing tips at the ends, with additionally inserted chrome elements The laser pump sources are placed in a separate housing so that they form three parallel optical channels, the first channel branching with the help of an optical Y splitter into identical second and third channels, contains a master single-mode laser and a lens focuser, in the rear focal plane of which the input aperture of the optical Y-splitter is placed, and in the second and third channels along the optical axes, an input lens focuser, a synchronized single-mode laser, and an output and a focus lens, the front focal planes of the input lens focusers are aligned with each other and with the output apertures of the optical Y splitter, and the rear focal planes of the output lens focusers are aligned with each other and with the output apertures of the optical Y-adder, while the input and output apertures are synchronized single-mode lasers are aligned, respectively, with the rear focal planes of the input lens focusers and the front focal planes of the output lens focusers, monizable single-mode lasers are mounted on thermocouples (refrigerators or heaters), and the output aperture of the optical Y-adder is combined with the input aperture of the optical fiber, while the laser pump source is electrically coupled to the master and synchronized single-mode lasers, the output of the microwave generator is connected to the master single-mode laser, and the microprocessor control and frequency stabilization is electrically connected to each of the thermocouples.

 The invention is illustrated in FIG. 1,2.

 The device (Fig. 1) contains a master single-mode laser 2, electrically coupled to a microwave generator 1 and fed from a pump source 3 and a lens focuser 4, which form the first optical channel that branches with the help of a Y-splitter 5 into two identical parallel optical channels, each of which contains input lens focusers 6, 7, synchronized single-mode lasers 8, 9 mounted on thermocouples 10, 11, electrically connected to microprocessor 12 for frequency control and stabilization, and output lens focus tori 13, 14, after which an optical Y-combiner 15 and the fiber 16 to optical splitters 17, ending focusing lugs 18 and the entire device except the pump source 3, the microwave generator 1 and the fiber 16 is placed in a common housing 19.

 The proposed device for therapeutic EHF exposure works as follows.

The radiation from each of the two synchronized single-mode lasers 8 and 9 at optical frequencies ν ₁ and ν ₂ , differing by the frequency f lying in the EHF range (Fig.2b, c) is introduced using lens focusers 13, 14 and optical Y-adder 15 into the optical fiber 16, through which they independently propagate and output from the output ends of the focusing tips 18, combined with areas of cellular structures subject to EHF exposure. The large inertia of biological tissue molecules at optical frequencies leads to the fact that the cell medium experiences electromagnetic influence at a difference frequency ν ₁ -ν _{2 of the} beats of two optical signals lying in the EHF range.

 The frequency f is tuned by changing the temperature of synchronized single-mode lasers 8, 9 using thermocouples 10, 11 (refrigerators or heaters).

The narrowing of the EHF signal band occurs as a result of optical synchronization of single-mode lasers 8, 9, for which the microwave generator 1 modulates the driving single-mode laser 2 with a harmonic signal at the microwave frequency F, resulting in the output radiation spectrum of the driving single-mode laser 2 (Fig. 2a) harmonics of frequency F appear, and the modulated radiation through the optical Y-coupler 5 and the lens focusers 6, 7 is introduced into both synchronized single-mode lasers 8, 9, while the components of the spectrum of the output signal defining one dovogo laser 2 at the frequencies ± nF, where n = 1,2,. . . the harmonic number of the frequency F coincide with the frequencies ν ₁ and ν ₂ , providing the capture and mutual synchronization modes, which leads to a narrowing of the EHF signal band at the difference frequency f.

 If the used synchronized lasers 8 and 9 have in themselves a narrow frequency band of their spectrum, then the elements 1,2,4,5,6,7 in figure 1 may be absent.

 The device for therapeutic EHF exposure can be implemented on gas, solid-state, semiconductor and other types of lasers emitting in a wide range of wavelengths of electromagnetic waves.

0,3 нм/^оС ( ~ 10 ГГц/^оС) могут быть расстроены по частоте на величину ν₂-ν₁ = 1200 ГГц, т. е., полностью перекрывая КВЧ-диапазон (30...300 ГГц) и обеспечивая КВЧ-стимуляцию не только на КВЧ-частотах, но и на их гармониках, что существенно повышает эффективность процессов восстановления жизнедеятельности клеток.Calculations show that when using standard TE microcoolers capable of altering the laser temperature ^of from 0 ° to ± 60 ^{° C} within 10 ^-3o C, two synchronized single-mode type semiconductor injection laser ILPN-216 emitting near λ = 1,3 mm and having coefficient of temperature sensitivity of the radiation frequency

0.3 nm / ^о С (~ 10 GHz / ^о С) can be detuned in frequency by the value ν ₂ -ν ₁ = 1200 GHz, i.e., completely overlapping the EHF band (30 ... 300 GHz) and providing EHF stimulation not only at EHF frequencies, but also at their harmonics, which significantly increases the efficiency of cell restoration processes.

The possibility of obtaining an EHF signal of beats after passing an optical fiber of a length of one meter is confirmed by analysis of the frequency-correlation function of the fiber, which, depending on the type of fiber, at a specified length drops to 0.5 from the maximum when ν ₂ -ν ₁ = = 500 ... 1200 GHz.

Internal modulation of the master single-mode injection semiconductor laser is possible in principle up to frequencies F _max = 40 ... 60 GHz, therefore, using a typical microwave generator with frequencies F = 5 ... 30 GHz and using harmonics of this frequency with numbers in the radiation spectrum of the master single-mode laser n = ± 3, ... ±, 5 to synchronize the oscillations of single-mode injection lasers at frequencies ν ₁ and ν ₂ , the difference beat frequency f can cover the entire EHF band (30-300 GHz), while the bandwidth of the EHF signal in depending on the power of the microwave generator (3 ... 10 mW) with sets Δ f = 10 ¹ ... 10 ³ Hz, i.e., lies within the limits necessary for a pronounced resonant EHF effect on the cellular environment. The latter circumstance significantly increases the efficiency of the process of restoring the vital activity of cell tissues.

Thus, the calculation of the parameters of the proposed device showed that:
1. The proposed device provides higher efficiency of the process of restoring the vital activity of cellular tissues, as it provides EHF effects not only at EHF frequencies, but also at the frequencies of their harmonics, while narrowing the band of the EHF signal sharply enhances the resonant nature of the effect.

 2. The proposed device has a transmission line of EHF exposure in the form of a fiber waveguide, i.e. more flexible, with smaller dimensions and weight and more convenient to use.

3. The proposed device has wider functionality, since due to the possibility of tuning the frequency within the entire EHF range and above, it provides an individual selection of the frequency of EHF exposure for each patient;
improves the focusing of the EHF field, which reduces to focusing the optical radiation into a spot with a diameter of less than 1 mm;
increases the number of patients simultaneously exposed to EHF exposure.
