Description

 Electrical stimulator and method of electrical stimulation

Technical field

The invention relates to the field of physiotherapy and neurology and can be used for electrical stimulation with low-frequency pulses of tissue, organs and nerves of the pelvis, as well as other zones ..

State of the art

A known electrical stimulator (see AS USSR N21803148, M. class A6 IN 1/00 from 10/31/1990), including a signal conditioning unit that contains a master oscillator, a power source and at least two electrodes.

Known electrical stimulator is intended for physiotherapy of diseases of the internal organs - the prostate gland and the treatment of chronic prostatitis. The pacemaker contains a serially connected master oscillator, generators, modulating pulses, a power amplifier, rectal and urethral electrodes, as well as a power source in the form of two batteries of the FL 2325 type. Using the device, a packet of mechanical pulses of ultrasonic frequencies is generated and they act on the prostate through the rectal electrode. In the intervals between the supply to the affected area of mechanical vibrations of packs of pulses of ultrasonic frequencies in the same area through the urethral electrode serves a unipolar pack of pulses of electric current in order to influence the diseased organ with electrical stimulation and electrophoresis.

The disadvantages of the above device is, firstly, that the device generates packs of electrical pulses of ultrasonic frequency, which are converted into mechanical vibrations affecting the diseased organs, and the electrical stimulation of the organs is carried out unipolar electrical impulses that are effective for electrophoresis, but not for electrical stimulation. And even such a low-efficiency electrical stimulation by unipolar electrical impulses is carried out in this device only during part of the procedure - in the intervals between exposure to the affected organ of mechanical ultrasonic vibrations. This significantly reduces the time of exposure to the diseased organ and reduces the effectiveness of both electrostimulation and electrophoresis, as well as treatment in general. The use of the urethral electrode for treatment is possible only in specialized medical institutions, which limits its use by the population for the treatment and prevention of diseases of the pelvic organs at home, and also requires special medical knowledge. The known device is characterized by complexity of design and inconvenience during the procedure, which leads to insufficient efficiency of its use.

The closest in technical essence and the achieved result to the claimed device is an electric stimulator, known from the description of the patent of the Russian Federation for the invention N "2089238 (M. Cl ⁷ A61N 1/36, decl. 02/12/1996, publ. 09/10/1997. ), including a signal conditioning unit, which contains a master oscillator, and also contains a power source and at least two electrodes, one of which is intracavitary.

The pacemaker also includes a generator power circuit breaker, a limiting resistor connected between the control input of the negative bus and the generator power circuit, and a trip indicator connected between the control output of the generator and the negative bus of the power source. At In this case, the signal conditioning unit is placed in a portable case with a removable cover and is spatially spaced with an electrode holder, one of which is connected to the output of the generator, and the second to its control input. The generator is configured to control the pulse repetition rate, pulse duration, repetition period of a packet of pulses, the number of pulses in a packet.

The electrode holder can be made in the form of a cylindrical rod with a rounded end, on the surface of which ring-shaped electrodes of a given width are placed, or in the form of a tablet, on the opposite sides of which electrodes are located.

The parameters of the signals of the pulse generator are:

- pulse duration 5-7 ms; - the period of the passage of pulses 20-28 ms;

- the duration of the pulse train 300-450 ms;

- the period of passage of the packets 2500-3500 ms.

The treatment time is 20-30 minutes for adults.

The electrode holder is inserted into the rectum to the depth of the metal electrodes. Procedures are performed daily or every other day. The course of treatment is 10-15 procedures. After the procedure, the electrode holder is sterilized.

The disadvantages of this electrical stimulator are its lack of effectiveness, which is due to the low accuracy of dosing radiation energy to the internal organs of the patient during physiotherapy, as well as the significant dimensions of the electrical stimulator.

The disadvantages also include the fact that an electronic device has been introduced into the electronic circuit of a known electrical stimulator, limiting the magnitude of the electrical stimulation current to 500 mA. Due to the fact that each person has an individual threshold of sensitivity to the effects of electric current, the established current limit of 500 mA may turn out to be too large for some patients, and too small for other patients. In this case, in the first case, patients will constantly feel unpleasant sensations during the procedure, and other patients, on the contrary, will not feel the effective influence of electrical stimulation.

The disadvantage is that the power source of the known electrical stimulator consists of two batteries of the type FL 2325, which, firstly, are characterized by insufficient power to conduct high-quality electrical stimulation and to obtain a packet of pulses with an amplitude of up to 18 V; secondly, they must be replaced with new ones after a certain time; thirdly, batteries after a certain amount of time begin to lose energy intensity, which can go unnoticed, but will worsen the quality of electrical stimulation.

Thus, the known device is characterized by low accuracy of controlling the impact on the patient, as well as the complexity of the design and inconvenience during the procedure, which leads to insufficient efficiency of its use.

There is a method of electrical stimulation (see Ukrainian patent for utility model JVb 10239, M. Cl. ⁷ A61N 1/32, declared March 20, 2005, published November 15, 2005), which includes a pulsed action of an electric stimulator on different organs, in particular pelvic organs.

Using a computer program or control equipment for controlling electric pulse exposure, the first step in the known method is the selection or modeling of pulse shapes, tropism and characteristics of their effects. The next step is programming sequences of similar and heterogeneous pulses in the packets, their duration, amplitude, polarity and frequency, as well as the values of the pauses between them, the selection of packets and, if necessary, the mid-frequency filling of the packets, the shape, amplitude, frequency and polarity of the pulses of which are also selected in the above manner, or carry out the selection of bursts of pulses with pre-installed software or controls for the control equipment for electric pulse exposure. The sequence of inhomogeneous pulses and their frequency-time and amplitude characteristics are established depending on the organs, structures and tissues that are affected. The third step is the selection of groups of pulse packets from some predefined modes or using the formation of groups of the created pulse packets, determine their linearity and cyclicity, then use the software to conduct amplitude, frequency and time modulation, which can be both within the packet and among groups or sequences of groups of packs. The formation of sequences of groups of bursts of pulses and their modulation is carried out, their cyclicity or linearity is set. The last step is to establish an algorithm for ordering modulated groups of pulses and their sequences, using software or control equipment for controlling electric pulse exposure, set the repetition frequency of groups and sequences of groups in the algorithm, set the envelopes for modeling the amplitude, current, and stochastic level and their hierarchy. They use biometric information acquisition devices - electrodes or sensors, the nominal and actual metrological characteristics of which are necessary for monitoring the impact of pulsed electrotherapy. In accordance with the metrological characteristics of the biometric information measuring devices used, a range of changes in the biofeedback parameters or controlled physiological processes is set for which the effect is synchronized and the level of correlation between their changes and the corresponding fluctuations in the parameters of the initial signals of the electropulse effect.

Immediately before using the electrotherapeutic effect, the individual sensitivity of the body to the physiotherapeutic factor and the degree of correlation between the applied channels with galvanic isolation, from the simpler, running wave type to complex modulated interference, are determined. In the case of prostatitis, two courses of 10 sessions of electrotherapy are carried out in a known manner, each day using transrectal and suprapubic areas of electrode application. In the treatment, three variants of the shape of myotropic pulses of the myotropic effect on smooth and lumbar-striped muscles and two variants of neurotropic action are used in the treatment.The cyclic and linear intervals of the noise spectrum, as well as several cycles with a mid-frequency, are included in the exposure algorithm filling one of the neurotropic and two of myotropic impulses. The intensity of exposure is adjusted by biological feedback with tissue impedance between the electrode E. Two galvanically isolated channels are used with a correlation of the effect of the type of modulated interference. The known method is difficult to use and expensive, since in the known method carry out multi-stage selection of modes and electrical stimulation is carried out using pulses of different shapes at the same time several options for low and medium frequency effects. So, in this way, the action is performed by pulses with an arbitrary shape of the initial signal of a precision stepless digital-to-analog formation and variability of a sequence of heterogeneous and homogeneous pulses of different shapes in packs, groups of packs and sequences of groups of packs. The closest in technical essence and the achieved result to the claimed method is the method of electrical stimulation, known from the description of the patent of the Russian Federation N ° 62017 for utility model (M. Cl ⁷ A61N 1/36, declared. 19.12.2006, published. 03.27.2007 d), including the pulse action of an electric stimulator equipped with an intracavitary electrode.

The pacemaker generates the initial signal in the form of a sequence of packs of bipolar pulses lasting 7 ms with a transmission frequency of 10-50 Hz and a filling frequency of 1, 2 kHz, which are fed to the treatment electrodes. However, the known method is characterized by low accuracy of regulation and inconvenience during the procedures, as well as the complexity of the design of the equipment used in its implementation, which makes the known method expensive and leads to insufficient efficiency of its use. Disclosure of invention

The basis of the invention is the task of improving the electrical stimulator, in which the new implementation of the elements of the device and the new connections between the elements of the device can optimize the impact on the patient by improving the accuracy of regulation and simplify the design and improve comfort carrying out procedures, which leads to increased efficiency of use of the device.

The problem is solved in that in the known electrical stimulator, which includes a signal conditioning unit, which contains a master oscillator, a power source, at least two electrodes, one of which is intracavitary, but in accordance with the claimed technical solution, is that it further includes a signal frequency control unit, a signal amplitude control unit, a mode switching unit and a bridge power amplifier, the input of which is connected to a power source, a signal conditioning unit made in the form of a series-connected unit for controlling the frequency of a signal, a master oscillator, a single vibrator, two inverters, between which a pulse generator and an adder are connected in series, while the bridge power amplifier with two inputs is connected in parallel to the second inverter, and its outputs are connected - the first through the control unit the amplitude of the signal to the first electrode, and the second through the mode switching unit to the second electrode.

But in accordance with the technical solution, it is also that the intracavitary electrode is made in the form of at least one body of revolution fixed on a solid rod, the end elements of which are symmetrically streamlined.

However, the intracavitary electrode is made in the form of a sphere with a diameter of 16-22 mm.

But it is also that the intracavitary electrode is made in the form of an ellipsoid of revolution. But also that the intracavitary electrode made in the form of two sequentially placed balls with a diameter of 16-22 mm.

A causal relationship between the set of essential features of the claimed device and the achieved technical result is that the claimed constructive design of the electric stimulator, namely, that it further includes:

- signal frequency control unit,

- a unit for controlling the amplitude of the signal; - a unit for switching modes and

- bridge power amplifier, the input of which is connected to a power source, while

- the signal conditioning unit is made in the form of series-connected signal frequency control unit, a master oscillator, a single vibrator, two inverters, between which a pulse packet generator and an adder are connected in series,

- the bridge power amplifier with two inputs is connected in parallel to the second inverter, and its outputs are connected - the first through the signal amplitude control unit to the first electrode, and the second through the mode switching unit to the second electrode, in combination with the known features of the device, simplifies the design and improves convenience when carrying out procedures, which leads to increased efficiency of use of the device.

Improving the effectiveness of the electric stimulator is achieved by providing the claimed design more accurate regulation and dosing of radiation energy to the internal organs of the patient during physiotherapy. At the same time ease of use, accessibility to the general public; miniature dimensions and compactness of the device.

These properties allow patients to conveniently use the device in any conditions, including at home, after consulting a doctor and reading the instructions for use.

The inventive electrical stimulator, in particular the elements included in it, and the connections between them ensure that the radiation energy of the sinusoidal pulsed, bipolar (for electrical stimulation) and unipolar (for electrophoresis based on electrical stimulation) modulated, adjustable in amplitude and frequency of currents, with bursts of pulses of a rectangular shape. Nerve and muscle fibers are most sensitive to sinusoidal impulses with amplitude modulation. With amplitude modulation implemented in the inventive device, a series of pulses with a certain frequency of current oscillations are separated one from one by gaps with zero amplitude. The effect of such series of current-carrying oscillations is intermittent, which significantly increases their effect on the tissues of the muscles and nerves of the person and reduces the body’s addiction to them.

The inventive design of the electrical stimulator, namely:

- implementation of the intracavitary electrode in the form of at least one rotation body fixed on a solid rod, the end elements of which are symmetrically streamlined;

The optimal dimensions of the intracavitary electrode are established empirically and provide, at the same time, a simple design, the greatest convenience during the procedures, which leads to an increase in the efficiency of use of the device.

The basis of the invention is also the task of improving the method of electrical stimulation, in which a new sequence of operations and new modes of their execution can optimize the impact on the patient by improving the accuracy of regulation and simplify the design of the device that implements the method, as well as improve the convenience of the procedures, which the effectiveness of the use of the proposed method. The problem is solved in that in the known method of electrical stimulation, including the pulsed action of an electrostimulator containing an intracavitary electrode, on the pelvic organs, in accordance with the claimed technical solution, it is new that the effect is carried out in the low-frequency range in the following modes: frequency oscillations in a packet, kHz 2.2-2.5 amplitude, V to 18 pulse packet length, ms 8-9 pulse packet frequency, Hz 2-8 N ovm is also that intracavitary electrode carry out a pulsed action in the low-frequency range, at least in two stages - first, pulses at a frequency of 2-4 Hz are supplied for 2-5 minutes, and then pulses are fed at a frequency of 5-8 Hz for 15-25 minutes. A causal relationship between the totality of the essential features of the proposed method and the achieved technical result is that the implementation of the intracavitary electrode pulsed exposure in the low frequency range in the claimed modes, together with the known features, provides increased convenience during the procedures and allows to simplify the design of the equipment used in it implementation, which reduces the cost of treatment of the claimed method and increases the efficiency of use the claimed method. The fact that the method is carried out in at least two stages:

- first, pulses are applied for 2-5 minutes at a frequency of 2-4 Hz;

- and then for 15-25 minutes they supply pulses at a frequency of 5-8 Hz in combination with well-known features also provides increased convenience during the procedures and allows to simplify the design of the equipment used in its implementation, which reduces the cost of treatment by the claimed method.

The optimal modes of the proposed method are established empirically and correspond to the natural vibrations of the cells of the body in the best way. Modes of impulse exposure outside the declared limits worsen the state of organs and cells of the body.

A brief description of the drawings The essence of the technical solution is illustrated by drawings, where - in FIG. 1 shows a diagram of an electrical pacemaker;

- in FIG. 2 shows embodiments of an intracavitary electrode (general view); - in FIG. 3 shows a view of the pulsed vibrations used in the claimed method.

The electrical stimulator includes a signal generating unit 1, which contains a master oscillator 2, a power source 3, at least two electrodes 4, 5, a signal frequency control unit 6, a signal amplitude control unit 7, a mode switching unit 8, and a power bridge amplifier 9, the input of which connected to a power source 3. The signal generating unit 1 is made in the form of a series-connected signal frequency control unit 6, a master oscillator 2, a single-vibrator 10, two inverters 11, 12, between which a pulse train generator 13 and an adder 14 are connected in series. In this case, the bridge power amplifier 9 is connected in parallel with two inputs in parallel to the second inverter 12, and its outputs are connected - the first through the block 7 control the amplitude of the signal to the first electrode 4, and the second through the block 8 switching modes to the electrode 5 (see Fig. 1).

The master oscillator 2 generates a signal with a certain amplitude and provides a meander of the desired shape. The signal frequency control unit 6 adjusts the frequency of the received signal. The one-shot 10, connected in series with the master oscillator 2, generates pulses of negative polarity at the output. An inverter 11 connected in series with a single vibrator 10 generates a pulse of positive polarity at the output. The generator 13 packs of pulses is connected in series with a single vibrator 10 and an inverter 12. When enable signal, which comes from a single-shot 10, the inverter 12 and the generator 13 packs form signals that fill the previously obtained pulses of negative and positive polarity. The output of the generator 13 bursts of pulses is connected to the input of the adder 14. At its output, a bipolar signal with negative and positive polarity is formed (see Fig. 3), which is fed through the inverter 12 to the power amplifier 9. The inverter 12 controls the operation of the power amplifier 9, to which the signal amplitude control unit 7 is connected. The power amplifier 9 through a switch / switch is connected to a power source 3, it converts a voltage of 220 V into a constant voltage of not more than 20 V. The mode switching unit 8 has two positions:

- 1 - mode of electrical stimulation with a bipolar burst of pulses and

- 2 - electrophoresis mode with simultaneous electrical stimulation.

In position 1, a packet of bipolar pulses from the terminals located on the device’s body (not shown in FIG. 1) goes through the plug and cables to the electrodes 4, 5. In this case, it does not matter which terminal the electrode is connected to. In position 2, a packet of pulses of negative polarity is obtained, which is fed through a terminal on the device body, the plug and cable to a passive electrode 5 for introducing a therapeutic substance with a negative ion polarity. A packet of pulses of positive polarity through block 7 control the amplitude of the signal and the terminal, which is placed on the device, the plug and cable is fed to the active electrode 4 for introducing a therapeutic substance with a positive polarity of ions. The electrical stimulator consists of a technological kit series-connected electronic units housed in a portable case with a removable cover.

The power source 3 and the electrodes 4, 5 are made with the possibility of detachable connection to the device through the terminals, plug and cable. The intracavitary electrode 4 is made in the form of at least one rotation body fixed on a solid rod, the end elements of which are symmetrically streamlined (see figure 2).

For example, the intracavitary electrode 4 can be made in the form of a ball with a diameter of 16-22 mm.

The intracavitary electrode 4 can be made in the form of an ellipsoid of revolution with a length of 40-70 mm.

The intracavitary electrode 4 can be made in the form of two sequentially placed balls with a diameter of 16-22 mm, placed at a distance of 10-60 mm between the outermost tangent to the balls.

The best embodiment of the invention

The inventive method is implemented as follows.

The generator of the electric stimulator produces excitation pulses of a bipolar form, formed in packs. Bursts of pulses are fed to the output of an electric stimulator, to which a cable is connected, connected to electrodes 4, 5, installed respectively on the area of influence (intracavitary) and on the skin

(percutaneous). The cable can also be connected simultaneously with two active electrodes. When the electric stimulator is initially turned on, the level of the initial voltage and the frequency of the bursts of excitation pulses are manually set to the minimum values. Then, in accordance with the chosen method of exposure and individual sensitivity of the patient, the necessary voltage amplitude is set to 18 V and the frequency of the burst of oscillation pulses.

Optimally, each packet of bipolar oscillations 8.5 ms long contains 19 pulses with a single pulse length of 0.45 ms. The interval between bursts of pulses is 130-450 ms. For physiotherapy, they use radiation energy of sinusoidal pulsed, bipolar (for electrical stimulation) and unipolar (for electrophoresis based on electrical stimulation) modulated, regulated by the amplitude and frequency of the currents, with pulse packets of a rectangular shape. Nerve and muscle fibers are most sensitive to sinusoidal impulses with amplitude modulation. The inventive method is carried out with amplitude modulation, when a series of pulses with a certain frequency of current oscillations are separated one from one by gaps with zero amplitude. The effect of such a series of pulses of current oscillations is intermittent, which significantly increases their effect on the tissues of the muscles and nerves of the person and reduces the body’s addiction to them.

Character. the patient’s sensations and the effectiveness of electrical stimulation is determined by the current parameters, namely, the frequency and amplitude of modulation, which should be close to the parameters of a living cell in vivo. When using an electric stimulator, the patient himself determines the threshold for the impact of energy on the diseased organ in accordance with his feelings and characteristics of his body. By turning the knobs of the blocks for regulating the frequency of the signal and the amplitude of the signal of the electric stimulator, the patient chooses for himself the most effective mode of stimulating the organ and comfortable state.

At a low modulation frequency, the oscillation pulses cause single contractions of muscle fibers. With an increase in the modulation frequency, sensations acquire the character of strong vibration, and with a further increase in the frequency of modulation - shallow, but deeper vibration. With a further increase in the modulation frequency and a decrease in the duration of current oscillation pulses, the excitability decreases and, as a result, the muscles stop contracting, not having time to react to these current oscillation pulses.

The mechanism of therapeutic effect is that when a sinusoidal impulse current with a rectangular shape passes through the tissues and nerves of human organs at the moment of rapid switching on and interruption of the current in the membranes of tissues and in the cell membranes, a sudden concentration of a large number of ions of the same name occurs. This leads to a change in the state of cell colloids and leads the cell into a state of excitement. In this case, the claimed device generates pulses of current oscillations acting on the nerve and muscle fibers with a frequency very close to the frequency of the potentials of the nerves, i.e. to the frequency of natural biocurrents. In the muscles, there is no violation of the norm and a pathological condition does not occur. With a slow increase in current, muscle disorders do not occur.

In the process of physiotherapy, the energy of pulsed modulated oscillations is converted into heat, which increases the temperature of the tissue of the patient’s organs. This leads to the excitation of cells and to the stimulation of lymph and blood circulation, the elimination of stagnant zones, to the activation of metabolic processes in the work of the organ and the whole organism. An important advantage of such oscillations is the absence of irritating current and damage to the surface of the organ tissue under the electrodes under prolonged exposure. In this case, sinusoidal modulated pulses, based on an alternating current of increased frequency, freely pass through the skin, almost not absorbed in it, and do not cause discomfort under the electrodes. Energy absorption of sinusoidal modulated currents occurs in more deeply located tissues along the entire current path. The stimulator works as follows.

The pulses from the master oscillator 2 enter the single vibrator 10 and start it. The single-vibrator 10 with its pulse allows the generator 13 bursts of pulses from the output of which through the adder 14 direct and inverting pulses are fed to the corresponding inputs of the power amplifier 9 with two outputs. From the first output of the bridge power amplifier 9, pulses through the signal amplitude control unit 7 and the electrode 4 act on the patient. The electrical circuit closes and the healing process begins. From the second output of the bridge power amplifier 9, the pulses through the mode switching unit 8 and the electrode 5 act on the patient.

Tests of the electric stimulator were carried out on patients in the following modes: oscillation frequency in a packet, kHz 2.2-2.5 voltage amplitude, V up to 18 pulse packet length, ms 8-9 pulse packet frequency, Hz 2-8 each packet contains pulses, units of 19 pause duration between bursts of pulses, ms 130 - 450.

The process of treating diseases using an electrical stimulator is as follows.

The handles of the signal frequency control unit 6 and the signal amplitude control unit 7 are set to the zero position, and block 8 switching modes of electrical stimulation to position 1. The intracavitary two-contact electrode is inserted into the rectum of the patient to the appropriate label. The device is turned on, the signal frequency control unit 6 is set to 5 Hz and the signal amplitude control unit 7 slowly sets the voltage amplitude level at which the patient feels a powerful and pleasant “beating” of the corresponding organ. The procedure lasts 20-30 minutes depending on the disease. In the inflammatory process of organs, a frequency of 3 Hz is first established and the procedure is carried out for 5 minutes. Under the influence of thermal energy and vibration, all capillaries of the stimulated organ are filled with blood. 5 minutes after the start of stimulation, a frequency of 5-6 Hz is set for 20-30 minutes.

The power is set so that the patient feels comfort at the maximum amplitude of the signal and the maximum "beating" of the stimulated organ.

When using a single contact rectal electrode and a flat electrode, a contact rectal electrode is inserted into the rectum, as described above, and a flat electrode is placed through the moistened cotton-gauze swab on the lower part of the pubis, where it is held by a medical urological belt. All other manipulations are performed as described above.

Electrophoresis based on electrostimulation is carried out by one contact rectal electrode and a flat electrode. It is carried out as described above, but the mode switching unit 8 is set to position 2. Before starting the procedure, a medical "cocktail" is introduced into the rectum using a medical rubber bulb, which corresponds to the polarity of the rectal electrode (+/-), and a cotton-gauze swab moistened with a medical "cocktail", which corresponds to the polarity of the flat electrode (- / +). The procedure is carried out for 20-25 minutes.

During the procedure, the patient independently adjusts the parameters of the effects of electrical stimulation (amplitude level and frequency) by turning the tuning knobs and getting the most comfortable sensations.

Bursts of pulses at a frequency of 2-4 Hz, delivered to the electrodes at the first stage of treatment for 2-5 minutes, improve blood circulation in the body area.

The bursts of pulses at a frequency of 5-8 Hz, which are applied to the electrodes for 15-25 minutes at the second stage of treatment, actually “trigger” the stimulated organ and create conditions for its best functioning, since their effect is optimally correlated with the operating mode of the living cell (5-7 Hz). The course of treatment is 10-20 treatment procedures. The bipolarity of the shape of the excitation pulses makes it possible to exclude various galvanic effects and provides a gentle current effect and, accordingly, good tolerance of the procedure.

Industrial applicability The industrial applicability of the proposed method and device is confirmed by the possibility of manufacturing an electric stimulator on known equipment in industrial production using known materials and means. So, for example, a signal conditioning unit, a signal frequency control unit, a signal amplitude control unit, a mode switching unit can be performed on standard logic elements of varying degrees of integration, given, in particular, on the website www.alldatache.net, which contains constantly updated information about products leading companies in the field of electronic technology, namely STMiсroelestroopis, NXP Semioproductors, Texas Istrumepts and so on.

The intracavitary electrode can be made of steel type 10X18H9T, which has anti-corrosion properties. The length of the working part of the electrode is 200-350 mm.
