Description

The invention relates to medicine, namely to traumatology and orthopedics.

A known method of stimulating reparative regeneration of bone tissue and a device for its implementation according to the patent of the Russian Federation No. 2165272, MKI 7 A 61 N 2/04, publ. 04/20/2001 g. [1].

The method is carried out by repeated exposure to a diseased area of a limb by electromagnetic waves without contact.

The patient site is placed in the field of the winding of the inductor, which acts as an element of influence. The coil is an integral part of the oscillatory circuit, at the terminals of which a signal of sinusoidal damped oscillations is supplied.

The known method and device have limited operational capabilities, for example, in the presence of elements of osteosynthesis, it is necessary to have a detachable impact element. The presence of only one frequency of exposure also reduces the magnitude of the therapeutic effect.

The objective of the invention is to increase the therapeutic effect while expanding the operational capabilities.

This is achieved by the fact that in the method of stimulating reparative regeneration of bone tissue by repeatedly contacting a diseased area of a limb in the postoperative period with electromagnetic waves by means of an action element, according to the invention, they simultaneously act on high-frequency fields, each of which is formed by a sinusoidal signal with a carrier frequency in the range of 100 -1000 kHz amplitude-modulated signal in the frequency range 10-1000 Hz and irradiation with low-intensity quasi-monochromatic aticheskim radiation in the visible and near infrared range with a small spectral width, the impact frequency fields is carried out using inductive emitters, each of which is part of the associated oscillatory circuit tuned to a frequency which differs from the frequency of the neighboring contour of 10-30%.

In the device for stimulating reparative regeneration of bone tissue containing a power source and an exposure element, according to the invention, the exposure element contains M inductive emitters, each of which is part of the oscillatory circuit of the corresponding oscillator of a high-frequency sinusoidal signal, and P elements of the visible and near-infrared radiation, dielectric a frame made in the form of a cylindrical surface with a section on which dielectric housings are fixed in the form with a lid, an inductive emitter is placed inside each case, the coil winding of which is laid in the form of a spiral on a flat dielectric frame, with each oscillator connected to a power source by means of an appropriate modulator, the radiation elements are combined into groups and connected to a power source through an appropriate modulator, In this case, the oscillatory circuit of each oscillator is tuned to its own frequency, and low-frequency modulators are used as modulators.

The essence of the invention lies in the fact that when stimulating the reparative regeneration of bone tissue, the tissues of a living organism are simultaneously exposed to high-frequency electromagnetic fields from M sources of electromagnetic waves and irradiation with low-intensity quasi-monochromatic radiation of the visible and near infrared ranges with a small spectrum width.

Figure 1 shows a functional diagram of a device for stimulating reparative regeneration of bone tissue, which implements the proposed method; figure 2 shows the device assembly; figure 3 shows the inductive emitter; figure 4 shows the device as a whole, in expanded form.

The device contains M sources of electromagnetic waves 1, 2, 3, 4. Figure 1 shows the option when M = 4.

Each of the sources contains an inductive emitter 5, 6, 7, 8, which is made in the form of an inductor.

The windings of the emitters through capacitors 9, 10, 11, 12 are connected to the circuits of the oscillators 13, 14, 15, 16.

The frequency of each of the oscillators is determined by the magnitude of the inductance of the corresponding inductive emitter and the capacitance value of the capacitor. Each of the oscillators through a low-frequency modulator (17, 18, 19, 20) is connected to a power source 21.

The device contains emitters 22 giving a light flux of the visible and near infrared ranges. Superbright LEDs emitting quasi-monochromatic radiation (half-height spectral width of about 20 nm) with different wavelengths are used as emitters.

Emitters are grouped. In each group, the emitters are electrically connected in series. The findings of all groups are connected in parallel. All groups of emitters through a low-frequency modulator 23 are connected to a power source 21. The power source can be made both mains and battery.

With a network power supply, the role of the modulator 23 is performed by the rectifier, assembled according to the bridge circuit. In this case, a pulsating voltage with a pulsation frequency of 100 Hz is applied to the radiating elements. Other options are possible.

Figure 2 shows the device assembly.

The device comprises a frame 24, which is made of a dielectric in the form of a cylindrical surface with a slit and holes. Cases 25, 26, 27 and 28 are fixed on the frame 24, in which inductive emitters 5, 6, 7, 8 are placed. The cases are closed by covers 29, 30, 31, 32. Hybrid circuits 33, 34, 35, 36 are installed on top of the covers with elements of auto generator circuits. The circuits are closed by casings 37, 38, 39, 40. Each of the circuits is connected with a flexible cable to a corresponding modulator. The power source 21 together with the modulators 17, 18, 19, 20, 23 are made in the form of a single functional element.

Figure 3 shows the inductive emitter assembly and without cover. The emitter includes a housing 25, which has the shape of a bowl and is made of high-quality solid dielectric.

An inductor 5 is fixed inside. The coil contains a flat dielectric frame made in the form of radially arranged petals with gaps 41. The coil of the inductance 5 made in the form of a spiral is placed on the frame, the wire of each spiral alternately bends around all the petals, while it goes around one or the other side of each petal of the frame, the number of petals is odd.

The housing 25 is closed by a lid 29, on which a hybrid circuit 33 is mounted using mastic. The circuit 33 contains a circuit of the oscillator 13. The circuit 33 is closed by a casing 37.

Figure 4 shows the device as a whole, in expanded form.

As can be seen from the drawing, the free space on the frame 24 is occupied by radiation sources 22. Sources with their conclusions are inserted into the holes that are in the frame 24.

On the reverse side of the frame, a connection of the leads of the emitters, which are combined into groups. Each of the groups is connected to the modulator 23.

The method is as follows.

Stretching the ends of the frame 24 by the diameter of the diseased limb, the device is installed over the area of the bone defect.

Turn on the device power circuit. The supply voltage with a modulator tuning frequency (in the range of 10 Hz - 1000 Hz) is supplied to the circuit of the corresponding oscillator.

In the presence of a supply voltage, each of the device's oscillators generates a sinusoidal signal with a carrier frequency in the range of 100 kHz - 1000 kHz, modulated by the low-frequency signal of the corresponding modulator. The voltage of the high-frequency signal on the winding of the emitter is 10-30 V. The magnitude of this voltage depends on the supply voltage.

Each of the emitters emits its own frequency, which differs from the neighboring one by 10-30%.

The signal on the emitter winding creates a high-frequency electromagnetic field, the direction of which is perpendicular to the plane of the inductor.

At the same time, the supply voltage is supplied to the modulator, and then to the emitting diodes.

A sick limb is irradiated by a combination of a large number of emitters giving a stream of visible light and adjacent near infrared ranges and the influence of electromagnetic waves from M sources.

The exposure value and the number of procedures in each case are set separately.

The proposed method for stimulating the reparative regeneration of bone tissue and a device for its implementation can significantly increase the therapeutic effect due to the effect of synergism of the influencing factors - the total effect exceeds the sum of the effects of each factor [2]. The impact on the fracture area by electromagnetic signals with different frequencies significantly increases the efficiency of bone tissue regeneration.

The presence of the dielectric frame of the device, made in the form of a cylindrical surface with a slit, expands the operational capabilities of the device.

The method and device have been tested experimentally in medical institutions of Omsk.
