How to choose the right electrosurgical generator for your Lab

An Electrosurgical Generator Unit, or ESU, is a medical device that uses an electrical current to cut and seal tissue. Whether you’re thinking of buying your first electrosurgical unit or are just considering upgrading your old model, it’s essential to do your research before purchasing.

Electrosurgery is a surgical technique that uses electrical energy to cut, cauterize, or coagulate tissue. It can be used in various Surgical procedures, including tonsillectomy, biopsy, and thyroidectomy. There are many different types of electrosurgical generators on the market, so how do you choose the right one for your hospital? This blog post will discuss the factors you must consider when selecting an electrosurgical generator. Stay tuned!

What is an electrosurgical generator?

An electrosurgical generator is a crucial part of the ESU. It works by generating electric currents that run the ESU unit. The electric current produced to power the active electrodes makes cutting, coagulation, and blending using the ESU unit possible.

It uses high frequency to run, ranging from about (100 kilohertz to 5 megahertz) interchanging currents at distinct voltages ranging from (200- 10,000) volts approximately. This charge is channeled into the subject tissue to cause localized heating in the area of surgery.

What is an electrosurgical unit used for?

An electrosurgical unit is a surgical machine used to control bleeding by coagulation, incise tissue, and destroy unwanted tissues or tumors through desiccation using electrical waves. All this is achieved by the high radio frequency (RF) produced by the high-powered generator, causing localized heating on the subject’s tissue under surgery. 

The increment in heat in these tissues makes it easy to destroy unwanted tissues, graft the skin or cause quicker clotting. Most electrosurgical units operate in two main ways, monopolar and bipolar modes. In the monopolar mode, an active electrode channels electric current to the surgical site, while the return electrode channels it away from the patient. In bipolar mode, both electrodes direct the electric currents toward the surgical site. 

There are three main types of electrosurgical units, namely, the High-Frequency Electrosurgical unit( HFEU), the Molecular Resonance Electrosurgical Unit(MREU), and the Ultrasound Electrosurgical Unit(USEU). All these units are used depending on the type of surgery being performed and the suitability of each unit in the specific surgery. For instance, if the surgery required the removal of a delicate tissue without burning it, the best unit would be an ultrasound electrosurgical unit (USEU).

How to prevent electrosurgical injuries

 Electrosurgical injuries can be devastating and often occur when doctors are not paying attention. In this post, we will discuss some easy ways to prevent these injuries from happening.

Taking off any jewelry, accessories, or implants on the patient’s body before entering the operating room

Since the electrosurgical unit works by channeling live electric currents to the patient’s body, having any metallic accessories would increase the risk of electrosurgical injuries. Metallic implants like heart pacemakers are dangerous during operations as the magnetic resonance may distort them, leading to burns. 

Removing them beforehand, therefore, minimizes this risk. If the patient cannot remove the jewelry for any reason, the surgeon should be informed beforehand so they know how to approach the issue. Also, they can use alternative technologies if the risk of an injury is too high.

Make sure that the patient has no contact with metallic objects.

Since the body is alive with electricity, coming in contact with any metallic object can cause unexpected movement of the electrosurgical pencil distorted radiofrequency. Therefore making sure that the patient is away from any form of the metallic object is advised.

Performing a preoperative assessment on the patients to check for any implanted electronic devices, metallic jewelry, or anything that can come into contact with the electronic currents

Doing this gives the surgeon the green light to proceed with the surgery, with the clarity needed to handle the patient, hence minimizing the risk of injuries.

Make sure the patients monitoring electrodes are in place

When placing these electrodes, avoid areas with implants and scars. Also, make sure that you clean the area thoroughly and shave the excess hair, as it is the most common cause of electrosurgical burns.

Never operate the electrosurgical unit with wet gloves

if the gloves have holes, they can pass electric current, which would lead to shock or burns. Also, while conducting this surgery, occasionally changing gloves is advised to minimize the chance of intraoperative shock or burns.

Factors to consider when choosing an electrosurgical unit 

An Electrosurgical unit or ESU is a medical device that uses an electrical current to cut and seal tissue. Whether you are thinking of buying your first electrosurgical unit or just considering upgrading your old model, it’s essential to do your research before making a purchase.

There are many factors to consider when purchasing an electrosurgical generator for your hospital. While price is always a consideration, selecting the right generator for your needs is essential. The right electrosurgical generator can help improve your surgical outcomes and safety.

Here are some factors to consider when choosing an electrosurgical unit:

1. Type of surgery being performed 

When purchasing a suitable electrosurgical unit for your hospital, the type of surgeries it will perform is vital. Some ESUs may be suited to conduct certain surgeries better than other competing machines. For example, for skin graft procedures, a device that lasts longer and has an inbuilt cooling system like the surgeon dual RF S5 (Ellman) would be suitable, as the process lasts longer.

2. The size of the hospital

The more the surface area to volume ratio of the hospital, the bigger the generator should be, as it would have to have the capacity to power various machines or stay charged for longer. Therefore, you will need to consider a powerful machine as a bigger hospital will have more patients, meaning more surgeries. In this case, you will also need to consider the durability of the generator.

3. How often will the generator be used

If the generator is used often, you need to purchase a powerful generator that can run smoothly for a long time while being used daily. Also, you need to factor in the ease of using such a generator as you do not want to take a long time plugging it in or cause injuries due to its complex nature. You may also consider getting one with an inbuilt cooling system to avoid overheating if the generator is constantly in use.

4. Power supply

The power supply is critical to the smooth running of any electrosurgical unit, as it needs the power to complete the circuit and conduct the surgery. If the power supply were cut or disrupted, the results would be hazardous to the patient and the third parties in the operating room.

Therefore, when purchasing an electrosurgical generator, you should be keen on the level of power it can supply without strain and the efficiency that comes with it. This is because electrosurgery is a complex process that is dangerous and should be treated with utmost caution to minimize the risks of injuries in the operating room.

5. Easy handling and maintenance

When choosing an electrosurgical unit, you must also consider all the people handling it. The ESU is handled by different staff, the most common being nurses, surgeons, and bioengineers. Because the generator will be in so many hands, purchasing the least complex one is advisable. Also, since the generator will need to be cleaned regularly as per OR regulations, it should be easy to clean and maintain.

6. Choosing one with Disposable accessories 

When purchasing an electrosurgical unit, you must determine if it has disposable units like electrosurgical pencils and changeable electrode pads. This is because this adds an extra cost to your initial purchase as you will keep buying these parts in the long run. So, when you are purchasing this unit, keep in mind the cost of the disposable accessories so you can make an informed decision on which ESU is the better one. 

7. Warranty

Warranty is the manufacturer’s time frame in which the product in question is guaranteed to work without fail. Therefore, purchasing an electrosurgical generator with a warranty gives you the reassurance you need while using it. Also, if the generator becomes faulty before the warranty time elapses, the manufacturing company repairs or replaces the whole unit with a new one; therefore, considering the generator’s warranty should be a no-brainer for you.
