Rating of the best EHVCh devices (electrocoagulators) for 2022

EHVCh devices are able to quickly stop bleeding, which contributes to the success of the 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 acts on biological tissues by means of high-frequency electric current. When choosing a specific option and method of application, it is able to solve such problems:

1. "Sew" some types of tissues, including muscles.
2. Stop the bleeding of the vessel by soldering.
3. Perform surgical poses and simultaneously cauterize tissue to minimize patient blood loss.

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

Types and design features of equipment

What are the products? There are two types of EHVCh, differing from each other in the ways of applying electric current to tissues:

View	Description
Monopolar	Differs in point influence on fabrics. The main area of ​​\u200b\u200buse is dismemberment. They are divided into two subspecies: contact (universal, budget, simple) and non-contact (used when it is necessary to make many 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. 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 options is quick and easy thanks to a 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 principle of operation of EHVCh is to convert high-frequency current into thermal energy. Tools with active and neutral electrodes, which, in contact with the fabric, create a full-fledged closed electrical circuit.

Modern electrosurgical devices are used for:

1. coagulation. Electrical energy is converted into thermal energy. 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 produced by a high-frequency high-density current, which is fed 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 formed, aimed at drying the vascular collagen. The steps 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. Devitalized areas are split due to metabolic processes.

The main advantage of EHVCh is the correct determination of the force of mechanical squeezing 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 its significant rise in price.

How to choose

The selection criteria depend on the needs of the hospital where the device is to be used. In turn, the availability of efficient 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, and the profile of the institution.

First of all, pay attention to the frequency of exposure to biological tissue. The higher the index, the more pronounced the cutting effect and the 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 scarring. For gynecology and otorhinolaryngology, devices for essential 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 of great importance. Powerful electrodes (balls) will help to quickly stop the bleeding. To carry out the excision, thin equipment (string or loop) is suitable.

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 directions in medicine.

The scope depends on the characteristics of the product:

• power and current form;
• set of options;
• functional;
• composition and quality of electrodes;
• possible pulse frequency;
• design features;
• the possibility of changing the polarity;
• automation possibilities;
• the number of electrodes used simultaneously;
• other indicators.

Which firm is better depends on the preferences of the purchaser. Every year a rating of quality goods from the world's leading manufacturers is published, it is possible to review new products, both budget and expensive. It is advisable to listen to the recommendations of users of this type of product.

Where to buy your favorite model? According to buyers, it is worth visiting a company store selling medical equipment. There, a qualified manager will help you choose the best products, tell you how much it costs, acquaint you with the possibilities, and pay attention to the advantages and disadvantages. Such points sell only certified products approved by the Ministry of Health.

You can order goods 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.
