Description

Fm.1

This invention relates to technical means used in traumatology and orthopedics, as well as in surgery.

An electrode device for treating an inflammatory process in tissues is known, which contains a direct current source and an active electrode in the form of silver wire connected to it.

However, this device is not efficient enough, since it is rigid and therefore traumatic for soft tissues, and does not contain a fixation element to the patient's body, which leads to electrode migration in the tissues and to the pain and additional trauma associated with it.

Closest to the proposed technical solution is an electrode device containing an active electrode in the form of silver wire with a holder of a flexible, bioinert tube ..

The disadvantages of the known device are the invasiveness, migration in the tissues, accompanied with pain and mechanical damage to the tissue structures: vessels, nerves, muscles, etc., the ability to generate only bactericidal silver ions, which is associated with toxicity.

The purpose of the invention is to provide a treatment for the inflammatory process in soft tissues.

The goal is achieved by the fact that an electrode device containing an active electrode, the outer surface of which is formed by a bactericidal metal, and a passive electrode connected to a constant current source, introduced at least one additional paired active electrode coated with another bactericidal metal. Each active electrode is fixed with a mushroom-shaped fixator leg made of a dielectric bioinert material, with the number of active electrodes chosen even.

The presence of a mushroom shaped retainer at the end of each active electrode eliminates migration and stabilizes its position in soft tissues. This eliminates trauma. Injury is also eliminated due to the active electrode being made of flexible elastic material.

The possibility of using not only one, but several electrodes simultaneously, increases the surface of their contact with infected tissues, which leads to an increase in output

bactericidal ions and shortens the treatment time.

The proposed electrode device eliminates toxicity, since at the same time soft tissues provide inflammation with various bactericidal ions, for example, silver and copper. Impact on fabrics with silver ions only (as in the prototype) is undesirable, since their low concentration is not effective, and is accompanied by a high toxic effect. The combined use of silver and copper ions in the antimicrobial process makes it possible to avoid these extremes and to achieve a synergistic effect by virtue of the possibility of using each of the ions separately in subtoxic concentrations.

Proposed Electrode Device

5 contains an active electrode made of a bioinert, flexible filament 1 coated with a bactericidal metal 2. A latch 3 having a mushroom shape is fixed at the end of the active electrode. Latch 3

0 made of dielectric, bioinert flexible material. Leg A of latch 3 does not contain a bactericidal metal coating, but may contain a coating of any other antiseptic agent, not

5 subject to electric current.

The length of the active electrode 1 depends on its size, the specific conditions of use.

0 If the electrode device is intended to treat small areas of the body, such as a finger, the active electrode has a length from fixer 3 to the opposite end of 3-6 cm. If

5, the electrode device is designed to treat inflammation of soft tissues in the thigh, buttock, the electrode device may be 40-60 cm long.

The length of the leg 4 of the clamp 3 depends on

0 anatomophotographic features, the thickness of the skin and ranges from 2 to 10 cm. The absence of a bactericidal metal coating on the stem 4 protects the skin and subcutaneous tissue from 5% of the frost during operation of the electrode device.

The opposite free end of the active electrode is also not covered with a bactericidal metal for some time, it is somewhat thinned. This end

serves to fix the needle to it and facilitates the conduction of the active electrode through the soft tissues of the human body during the installation of the electrode in the tissues of the human body. The diameter of the active electrode 1 also depends on the specific dimensions of the electrode device and ranges from 0.5 to 2-3 mm.

The extended part of the fixer 3 has a rounded shape (with a diameter of, for example, 2-10 mm), can be made solid or perforated and does not contain a coating of bactericidal metal 2 in order to avoid skin necrosis.

The proposed electrode device is used as follows.

Previously in the operating room, the corresponding part of the body is treated with alcohol and iodine, and this area of the inflammatory focus is anesthetized. The free, tapered end of thread 1 is punctured into the needle's eye (straight or curved — it depends on the anatomical and topographic features of the inflammatory soft tissue center). In accordance with the choice of the intended optimal path for placing the electrode in inflamed tissues, the skin and wire are punctured A needle with a hooked electrode through a thick layer of soft tissue and the needle pulled all the way to the surface of the skin. Next, pushing the needle, pull the end of the electrode out. In this case, the extended base of the retainer 3 rests on the underlying area of the skin (in the place of the initial injection). After such an immersion of the electrode in soft tissues, the portion of the filament 1 protruding above the skin is cut off at its border with a coating of bactericidal metal 2 and the end of the electrode is attached to the positive pole of the current source. In order to avoid burns and necrosis of the skin, the area of the electrode in contact with the skin is pre-isolated with a bioinert polymer tube.

In a similar manner, the required number of electrodes is additionally installed in soft fabrics. Usually, at least a pair of active electrodes coated with various bactericidal metals are used. It is important that the distance between the active electrodes in soft tissues is not less than 20 mm, since it ensures uniform diffusion of silver and copper ions in the tissues, which is very important for reducing the inflammatory process in the tissues.

Every single active electrode. contains a coating of 2 only from silver or from copper (or another bactericidal metal). When installing electrodes in inflamed tissues, their number varies from 2 to 6-8, depending on the size of the infiltrate, the severity of the inflammatory process in it, the virulence of microorganisms sown from the focus, etc.

It is important to observe the sequence of placement of the active electrodes on the basis of the type of coating 2, since this provides 10 each area of inflamed tissue with ions and silver and copper simultaneously, which will allow to potentiate the antimicrobial effect in the infiltrate due to the synergistic effect of these ions. In addition, low doses of the initial ions are required to achieve the bactericidal effect, which eliminates toxicity when using electrodes. Therefore, in each specific case, it is advisable to use a pair of 0 active electrode electrodes: silver and copper.

After the required number of active electrodes and in the desired directions are carried out in the manner described, their free ends 5 are connected to the positive pole of the current source. Passive electrodes are attached by placing them on the skin in an optimal position.

Sterile wipes are placed on the skin areas (around the fixer 3) at 0 entry points, as well as the release of the active electrodes from the body. Adjust the current density are depending on the severity of the inflammatory process. The active electrodes 5 are in the infiltrated tissues x until the end of treatment. After elimination of the inflammatory process, they are removed as follows. The galvanostat is disconnected, the ends of the active and passive electrodes are freed from the positive and negative poles, and they proceed to the removal of the active electrodes from the body. Tighten the vacated end of the active electrode by cutting it off with scissors, removing 5 soft tissues. After that, having taken hold of the extended base of the lock 3, it is easy to remove the electrode to the outside. The holes on the body are smeared with antiseptic and impose

sterile wipes until they heal. 0. The proposed device is well tolerated by the patient, does not cause pain and does not limit the activity of the patient, does not require him to rest in bed. The proposed device can be used in the treatment of inflammatory processes in soft tissues caused by paraphlebitis, lymphangitis, abscesses in the infiltration stage, erysipelatous inflammation, etc. The elasticity of the electrode, unlike the prototype, does not injure the tissue. The expanded base 3 stabilizes the electrode, eliminates its migration into tissues.

The use of both silver and copper electrodes with their strict alternation eliminates toxicity, increases the antimicrobial effect, reduces the treatment time by 1.5-2 times, as it allows locally creating a depot of antimicrobial agents with a wide spectrum of antimicrobial action in the thickness of the inflammatory focus.
