Rating of the best EHVCh devices (electrocoagulators) for 2020

EHHF devices are able to quickly stop bleeding, which contributes to the successful operation. Indispensable in such branches of medicine as thoracoscopy, surgery, gynecology, neurosurgery, laparoscopy and others. The best manufacturers have launched the production of professional devices with a quality certificate.

What it is

EHVCh apparatus or scalpel - electrosurgical coagulator - an instrument that affects biological tissues by means of high-frequency electric current. When choosing a specific option and method of application, it is able to solve the following tasks:

1. Sew some types of tissue, including muscles.
2. Stop the bleeding of the vessel by soldering.
3. Perform surgical pose and cauterize tissue at the same time to minimize patient blood loss.

Currently, this device is an integral part of any operation. Its use makes it possible to shorten the time of surgical intervention, to reduce blood loss.

Types and design features of equipment

What products are there? There are two types of EHHF, which differ in the methods of supplying electric current to the tissue:

View	Description
Monopolar	Differs in a point effect on tissues. The main use is dismemberment. They are divided into two subspecies: contact (universal, budget, simple) and non-contact (used in the case when it is necessary to make multiple incisions on one organ in order to minimize thermal trauma to adjacent tissues).
Bipolar	There is an effect on the tissue located between the two electrodes. It is used to stop bleeding in large vessels.

Popular models of electrocoagulators are able to function in several ways. The surgeon can choose the optimal power and a certain basic option:

• bipolar coagulation;
• cutting;
• superficial coagulation;
• other functionality.

Switching between options is quick and easy thanks to the simple interface on the power supply unit. The manufacturer produces models with the function of manually saving the parameters set by the doctor as basic.

Operating principle

The main operating principle of EHHF is to convert high-frequency current into thermal energy. Instruments with active and neutral electrodes, which, in contact with the tissue, create a full-fledged closed electrical circuit.

Modern electrosurgical devices are used for:

1. Coagulation.There is a transformation of electrical energy into heat. The fabrics are heated to a temperature of 60 to 100 degrees. The extracellular and intracellular fluid is evaporated. The cellular structure is not damaged.
2. Cutting. The effect is a high-frequency high-density current that is applied to the point of application of the active electrode.
3. Ligation. One of the most popular methods for sealing vessels. A high-frequency current pulse is applied to the damaged area of ​​the vessel, which determines the resistance of the compressed walls. After analyzing the data, a signal of a certain strength is generated, aimed at drying out the vascular collagen. Actions are repeated until the walls of the vessel are completely sealed.
4. Devitalization. The main task is to purposefully destroy tumors or abnormal tissues. The temperature regime is set from 50 to 60 degrees. The process of destruction begins. The devitalized areas are cleaved by metabolic processes.

The main advantage of EHHF is the correct determination of the force of mechanical compression of the vessel walls and the control of the current supply.

Advantages of the ligation process:

• works with large vessels;
• significant speed of action;
• full automation of the process;
• during operations, medical error is practically excluded;
• no additional tools are needed: clips, clamps, material for tightening wounds.

The presence of this function in the coagulator leads to a significant increase in its cost.

How to choose

The selection criteria depend on the needs of the hospital in which the device is supposed to be used. In turn, the availability of effective and functional equipment in the hospital increases the capabilities of the medical institution and its prestige. Which one is better to buy depends on many factors: the financial capabilities of the buyer, the professional training of medical personnel, the profile of the institution.

First of all, attention is paid to the frequency of exposure to biological tissue. The higher the index, the more pronounced the cutting effect and less the coagulation effect. Plastic surgeons need a device with a significant frequency (2.64 - 5.28 MHz) and separate coagulation and cutting modes to negate the appearance of scars. For gynecology and otorhinolaryngology, devices for significant coagulation are more suitable so that neoplasms can be quickly removed. Preference is given to products with a frequency of 440 kHz.

Properly selected electrodes are essential. Powerful electrodes (balls) will help to quickly stop bleeding. A thin piece of equipment (string or loop) will do the excision.

What to look for in order to avoid mistakes when choosing? The scope of use of electrocoagulators is quite extensive:

• gynecology;
• urology;
• surgery;
• visceral surgery;
• cardiac surgery;
• traumatology;
• neurosurgery;
• gastroenterology;
• pediatric surgery;
• other areas in medicine.

The scope depends on the characteristics of the product:

• power and current shape;
• a set of options;
• functional;
• composition and quality of electrodes;
• possible pulse frequency;
• design features;
• polarity reversal possibilities;
• automation capabilities;
• the number of electrodes used simultaneously;
• other indicators.

Which company is better depends on the preferences of the purchaser. A rating of high-quality goods from leading world manufacturers is published annually, you can review new products, both budget and expensive. It is advisable to heed the recommendations of users of this type of product.

Where to buy the model you like? According to buyers, it is worth visiting a branded store selling medical equipment. There, a qualified manager will help you choose the best products, tell you what it costs, familiarize yourself with the possibilities, pay attention to the advantages and disadvantages.Such points sell exclusively certified products approved by the Ministry of Health.

You can order the product online in the online store. The average price will be slightly lower, but there is no guarantee that a low-quality fake will not come instead of the popular expensive model.
