Electrosurgical Unit Guidelines from Heal Force

Electrosurgical Unit Definition:

Electrosurgical unit are devices that use high-frequency (HF) electrical currents to cut or coagulate tissue during surgery, known as electrosurgery. It consists of an electrosurgical generator that transforms electrical energy into HF current. It is operated using a specific control. Utilizing the concentrated heating effect of high-density high-frequency current on the local biological tissues, the tissues or tissue components are vaporized or burst to achieve the purpose of medical operations such as coagulation or cutting.

Electrosurgical generators(ESU) have the features of good effect, little damage-less bleeding, it has a bactericidal effect which can shorten the operation time and facilitate postoperative recovery. If equipped with an argon gas controller, it can also significantly improve the cutting and coagulation effect, improve the working environment, and reduce the degree of scorch.

What are The Types of Electrosurgical Units?

There are different types of electrosurgical units that use different sources of energy: radio frequency or high-frequency, ultrasound, and molecular resonance. The two types of electrosurgery most commonly used are high-frequency electrosurgery and electrocautery. There are a variety of options in terms of commercially available electrosurgical generators. Most have both monopolar and bipolar options, and they offer pure cutting, pure coagulation, and blended (cut/coag) current modes. With monopolar electrosurgery, the current passes from the active electrode to the target lesions through the patient's body and finally exits the patient via a return electrode. With bipolar electrosurgery, the current only passes through the tissue between the two electrodes of the instrument.

Heal Force EB03 Electrosurgical Generator has 6 monopolar and 1 bipolar output. 

Heal Force EB05 Electrosurgical Generator has 7 monopolar and 3 bipolar outputs.

Electrosurgical Unit Working Principle:

The high-frequency electrosurgical generator uses the thermal effect of electric current to achieve the surgical effect of cutting and coagulation. The high-frequency current is applied to the surgical site through the surgical electrode (scalpel head). Since the area of the electrode touching the human body during the operation is very small, the current density under the electrode is very large, so strong heat energy is generated instantly. This heat energy acts on the human cells, causing the tissues in the cells to evaporate explosively and the cells are destroyed, so as to achieve surgical effects such as cutting and coagulation.

Several Concepts of High-frequency Electrosurgical Unit:

Electric Cutting:

When we use a continuous high-frequency current waveform, the current generates a lot of heat and extremely high temperature in an instant. This temperature vaporizes the cell tissue and separates the tissue. This is the effect of electrocuting.


When the output current waveform is intermittent, the instantaneous heat generation is greatly reduced, and the temperature is relatively low, which is not enough to vaporize the tissue and only produce the effect of scalding, that is, the electrocoagulation effect.

Mixed Cutting:

When the output current waveform is between electrosurgical resection and electrocoagulation, and two mixed waveforms, the surgical effect of electrosurgical surgery is a kind of simultaneous resection and coagulation.
