The invention relates to medicine, namely to ophthalmology, and can also be used in traumatology, otolaryngology, Nephrology, in the treatment of atrophy of the hearing aid.

There is a method of treatment of diseases of the optic tract and the device for its implementation through the implantation of highly inductive coil and the magnetic pulse inductor. When this coil is implanted and sutured to the sclera under tenon's membrane in the plane of the equator of the eyeball, where one electrode is placed retrobulbarno near the optic nerve, and the other in the Equatorial plane of the eyeball. C. N1799577).

The inductor operating pulse, due to the alternating magnetic field induces in the implantable coil bipolar pulsed electric current, which in conjunction with the magnetic field and is curative. These effects synchronized with the systolic pulse wave.

However, these method and apparatus have disadvantages. The duration of the pulse current in the implanted coil is small, which decreases effektivnosti coils in implantable coil, or with the necessary increase in the magnetic field pulse. The first is connected with the increase of the dimensions of the implantable coil, which is unacceptable, and the second with the magnitude of the current in the inductor, which increases thermal selection in it and reduces the continuous operating time. In addition, the induction of currents in the implantable coil there is no possibility of increasing the duration of the electric signal and its modification in the form of "bundles" of pulses, there is no possibility of simultaneous, synchronized exposure light flux along with the influence of magnetic field and electric current.

The technical result according to the invention is the improved treatment of diseases of the optic tract.

The technical result according to the method is achieved in that in the method of treatment of diseases of the optic tract by implantation of highly inductive coil on the eyeball at the equator, with the induction of it affecting currents from an external inductor and synchronization effects with the systolic pulse wave, according to the invention, the implantable coil for> additionally affecting high-frequency electromagnetic fields up to 200 A passage of sustain pulses in the mode sweep from 20 Hz to 50 Hz at a voltage of not more than 15, and also provide the light in the visible or infrared wavelength range power up to 10 mW, and the session duration of these impacts provide for no more than 30 minutes daily when the number of sessions no more than 15 per course of treatment.

One option is one in which light exposure provide in the Equatorial region of the eye. Another option is the provision of light exposure area of projection of the Central fossa on the sclera.

The technical result according to the device for the treatment of diseases of the optic tract is achieved by the fact that the device for the treatment of diseases of the optic tract, containing implantable coil with two or more electrodes and the source of the magnetic field in an external inductor connected to a pulsed current source according to the invention the electrical circuit of the implantable coil is provided with an additional rectifier and a light source, and an external inductor is provided in addition emitter high frequency electromagnetic fields, connected in a power supply and a high-frequency generator, which includes the driver packs and the pulses from the sweep generator, WMO is rum light sources placed in the implanted coil.

In another embodiment, the light sources are placed on one of the electrodes.

The technical result is also achieved by the fact that the synchronizer run driver contains external sensor systolic pulse wave which is placed on the patient.

The authors have carried out the necessary experimental work, which allowed to determine the necessary parameters affecting the electrical signals of voltage due to the implanted coil, including light sources, and frequency of their repetition.

The light source in the implantable coil, the electrical signals in the mode sweep frequency of their repetition within each "pack" and frequency repetition "packs", corresponding to the repetition rate systolic Bay vessels when passing them in the pulse waves selected from the following considerations.

Due to the fact that each of the effects (magnetic, electric and light) has a certain specificity; their co morbidity gives the effect was higher than their independent effects.

Magnetic field, as shown by our biophysical and clinical research, increases the speed of blood flow (including microvessels), conformia if this is ation of oxygen increases the production of ATP in the mitochondria of cells and activates cell metabolism.

Electric shocks by introducing negative charges contributes to the narrowing of the threshold sensitivity of neurons and axons, reduction of concentration by membrane-linked calcium blocker, reduces or eliminates inflammation, speeds up metabolic processes in tissue structures.

Light exposure in the range of visible or infrared wavelengths due to the internal photoelectric effect, ultimately, is identical with the electric impact. However, unlike electric impact, where it is necessary to use at least two electrodes, and the distribution of currents between the electrodes is not regulated and the impact area of an indefinitely large, light exposure does not require electrodes and a localized region of light absorption, which is usually small, because small free path length of photons. However, the last two methods, the effect is quite good complement each other. Due to the internal photoelectric effect when exposed to light, the electrical conductivity of the exposed area increases and the threshold voltage electrical effects can be reduced, because it increases the current between the electrodes. In addition, photons, pohodami out through the membrane. This increases the positive potential inside the cells, cropped areas of inflammation, in which the potential is excessively positive, which reduces the rate of metabolic processes.

Thus, a combination of factors, complement each other, creating a common higher clinical effect.

Due to the fact that all impacts are synchronized between self - starting pulse magnetic field is provided in conjunction with the launch of the high-frequency generator, and electrical and light signals are induced due to high-frequency electromagnetic radiation, occurs practically simultaneously the impact of all factors.

The maximum induction of the external magnetic field will be the value of 0.3 to 0.5 T, the frequency of high-frequency radiation from 2.0 to 2000 kHz, the magnitude of the electrical signal at the maximum of 15 In the form of "packages" swierklany pulses with a repetition frequency of "packs", is equal to the frequency of the pulsations of blood flow (heart rate), when each "pack" is excited by the passing of the systolic pulse wave. Because each implantable coil provided with light sources of red, blue, green, germanium / is electrodom implantable coils form a luminous flux of up to 10 mW.

Clinical practice has shown that the duration of the session steps should be 10-20 minutes, and the number of sessions per course of treatment should not exceed 15 sessions. The session duration is less than 10 minutes pulsed exposure is not effective. With a duration of more than 20 minutes there is a phase of braking, which disappears in 1.5-2 hours. However, the patient may experience discomfort due to emerging headache, which passes through 0.5 hour - 1 hour.

The invention is illustrated by drawings, where Fig. 1 shows a General view of the device.

In Fig. 2 shows a variant of the implantable coil with light sources in the center of the coil.

In Fig. 3 shows a variant of the implantable coil on the end of one of the electrodes.

In Fig. 4 shows a block diagram of the power system and control the operation of high-frequency electromagnetic field emitter. The device includes implanting the spool 1, the rectifier diode 2 or axle 3, and the diode rectifier 2 is connected in series with one of the electrodes 4 and the rectifier bridge 3 is connected in parallel to the current terminals 5 coils 1 and loaded on the electrode 4. The light sources 6 are connected in parallel to the electrodes 4.

At magnitnogo field 8, the power supply unit 9, the high frequency generator 10, the imaging unit 11 "packs" pulses with a built-in sweep generator 12, the synchronizer 13 carried by the pulse wave sensor in the vessel 14, the pulse current source 15 for powering external inductor 7.

The method and the device are performed as follows. Implanted coil 1 on the eyeball in a known manner. While the light sources 6 are placed either in the Equatorial region of the eyeball, or in the projection, the Central fossa on the sclera. Post tweeter 8 on the area of the outer edge of the orbit of the eye, when the distance between the implanted coil 1 and the emitter 8 is minimal, and their planes are parallel. Connect the sensor synchronizer 13 to the patient. Include the power supply unit 9, by setting the minimum pre-power high-frequency radiation, and record the presence of signals of the synchronizer 13. Pick up power-frequency radiation, in which the patient sees a flash of light source 6. Power increase up to values corresponding to the discomfort of the patient. Session exposure is carried out in 10-20 minutes depending on the complexity of the pathology and adverse effect the high-frequency generator 10 and the pulse current source 15 for powering external inductor 7.

The modulating signals from the sweep generator 12 is fed to the input of the high-frequency generator 10 and form a "stack" "swierklany signals. The repetition frequency of "packs" is determined by the signals of the synchronizer 13. Level value svopirovanie high-frequency signal varies prior to its submission to the emitter of an electromagnetic field 8. Because implantable coil 1 is a kind of antenna, the modulated electromagnetic fields excite electromotive force in the circuit of the current terminals 5. In the presence of a rectifier diode 2 it will be provided unipolar unidirectional current, a bridge 3 will provide full wave rectification. Output active electrode 4 is placed after the diode 3 or at the output of the bridge 4. The light source 6 is placed in an electrical circuit in parallel to the electrodes 4. Geometrically they are placed either in the center of the implantable coil 1, or on one of the electrodes 4.
