We’ll go over how it works and why it’s utilized and why it’s essential in modern surgical procedures. No complicated terms from science only clear and concise answers backed by real world examples that you can visualize and recall. Let’s eliminate the confusion of the equation to aid you in understanding it.
Electrosurgical units – How they Work and How to Use them Safely
It is the Electrosurgical unit (ESU) uses an electrical current of high frequency that is used to break, dissolve or cut soft tissue. The generator generates the energy and passes this through an electrode which is positioned to touch the surgical area. The current travels through the patient and is released via a return electrode, similar to the dispersive pad. It is put on a moist and veined skin area to prevent the risk of thermal injury.
Correct return pad placement and clean electrode tips and following operating room procedures can prevent sparks and arcing electric burn, dangers from fire. Utilizing the correct medical cauterization method, cut or coagulate, keeps the procedure safe. The trained staff should be aware of the handpiece, generator settings and the dispersive electrode to avoid leakage of current or burning of the grounding pad in patients who undergo electrosurgery.
Theory of operation
The electrosurgical unit principle of operation that is employed by the operation of an ESU is based on an alternating high frequency current that passes through the tissues. This current creates heat because of electrical impedance which causes tissues to shrink, melt, or even be cut cleanly. The electrode’s tip should be placed in contact with the tissue with precision and the power settings must be in line with the type of wet field cautery, or dry field.
In monopolar electrosurgery the active electrode sends electrical current through the patient while a return electrode, or dispersive pad takes it in. Bipolar electrosurgery is where bipolar forceps transmit and receive current through an area of only a few inches, thus avoiding the requirement for an earthing pad. Both procedures require secure setting, a medical equipment check as well as following medical safety protocols to ensure the safety of patients.
Principle of surgical diathermy
The basic principle behind surgical diathermy is based on the use of high frequency currents to generate the tissue with heat. This procedure works by causing thermal destruction, not cutting. The electrosurgical generator is sending the tissue with an alternating current the heat generated causes cells to dissect, coagulate or even ignite, based on the waveform and the power.
Electrocautery is different from. electrosurgery differs due to the fact that electrocautery utilizes the direct the current (DC) and doesn’t pass through the patient’s body, whereas electrosurgery does. In thermocautery a sharp heated edge is used to reach tissues directly. This makes electrosurgery more efficient for areas with blood vessels and for delicate tissue dissections in medical procedures.

Block Diagram of ESU
A block diagram for an Electrosurgical device (ESU) comprises key elements that include the handpiece, generator an active electrode as well as a return electrode along with the electric circuit that runs through the patient. The generator controls the waveform mode, power, and waveform. The active electrode provides energy, and the dispersive pad is safe to collect the current.
Below is a simple table showing the main parts of an ESU and their functions:
| Component | Function |
| Electrosurgical Generator | Produces high frequency current |
| Active Electrode | Sends current to the surgical site |
| Return Electrode | Collects current from the body |
| Dispersive Pad | Prevents burns by spreading return current |
| Surgical Handpiece | Holds the electrode and controls energy delivery |
| Patient Grounding | Ensures safe current flow and avoids electrical shock |
A proper skin preparation, the use of conductive gels and avoiding the use of flammable agents are all important to electrosurgery security. It is important to be cautious when it comes to the cleaning of electrode tips and medical device precautions to ensure the safety of the environment in the operating room and ensure the safety of devices for surgical energy in Pakistan hospitals.
PRINCIPLES OF ELECTROSURGERY
It is the electrosurgical unit principle (ESU) works by using high frequency electricity in order to slice, reduce or coagulate tissues during surgery. The generator transmits the alternation stream of electricity (AC) through the handpiece, which has an electrode which is in contact with an operating field. The AC flows through the patient, and then it exits with safety via a dispersive electrode, or return pad.
The procedure relies on a safe grounding of the patient and proper return pad positioning, and the placement of conductory gel applied to the skin that is vascularized and moist. Follow operating room procedures avoid flammable agents and avoiding electrical arcing are essential to electrical burn prevention. The ESU utilizes either monopolar or bipolar electrosurgery. Both of which require careful handling and regular cleaning of the electrode tips.
Electrocautery
Electrocautery utilizes the direct the current (DC) to warm the electrode’s tip which is then used to burn or seal tissues directly. The current doesn’t travel across the person, which makes it distinct from electrosurgery. It is used to treat thermocautery, either in wet or dry procedure.
This procedure is safe in certain medical cases of cauterization as it prevents an electrical circuit that flows through the body, which reduces the risk of electrosurgery. However, it yields slower results and is not as precise than high frequency surgery that is used in the modern medical equipment to treat tissue dissection and the coagulation process.
Electrosurgery
Electrosurgery is the process of passing a high frequency electric flow through the body of the patient to generate heat in the targeted area. The current originates from the electrosurgical generator, and passes via an electrode that is active that is attached to the surgical handpiece. It is used for cutting or coagulating of tissues.
The procedure relies on the careful interaction with tissues proper power settings and a safe returning electrode, or dispersive pad. Monopolar electrodes are used because the current pathway is lengthy and in bipolar forceps, it moves through the tip and back. Both require security checks to prevent the possibility of leakage of current, thermal damage or burns to the pad of grounding.
What is the difference between electrocautery and electrosurgery?
The primary distinction is that electrocautery draws energy from an electric current that is directly applied to the tissue, whereas electrosurgery utilizes alternating high frequency current which flows across the body. Electrosurgery is more sophisticated and is suitable for cutting, dissecting, and coagulating tissues.
Electrocautery is different from. electrosurgery is also different in regards to safety. Because electrosurgery involves an the flow of electrical energy that is a requirement to follow operating room safety procedures and medical device safety precautions and close supervision of biomedical engineering. On the other hand thermocautery instruments like heated probes do not create an electrical impedance within the body, which reduces the possibility of electrosurgery in ophthalmology and close to flammable zones.
ELECTROSURGICAL UNIT (ESU)
It is Electrosurgical unit (ESU) can be described as an instrument used in medical procedures that utilizes high frequency electricity for cutting, curing or shrink tissues during surgical procedures. It aids surgeons to work without causing bleeding with the help of surgical energy, which travels without danger through the electrical circuits within the body.
The electrosurgical generator transmits an AC or alternating electrical current (AC) directly to an active electrode of the handpiece for surgery. The current flows through the body of the patient, it then returns to the generator by using an electrode dispersive or return pad. This technique improves the dissection of tissue and reduces the risk of injury to the body when grounding of the patient and operating room procedures are adhered to.
Circuit
The ESU circuit comprises the active electrode, the generator patient, active electrode, and the return electrode. The electrical circuit begins from the generator, flows through the electrode’s edge, then flows through the surgical field and then exits through an electrode pad that disperses.
This pathway needs to be safe and clean. A properly prepared skin, conductive gel and return pad placement can prevent electric burn, arcing and sparking or leakage of current. Making sure the circuit is solid and complete protects patients from heat injuries in the electrosurgical process.
Types of ESU
Electrosurgery is carried out by using two types of Electrosurgical unit (ESU) that are monopolar electrosurgery and bipolar. Both employ high frequency surgery, however they are different in their methods and pathways of current.
In monopolar electrosurgery the current is able to flow across the entire patient which requires the use of a dispersive pad. Bipolar electrosurgery means that the current flows only between the two sides of bipolar forceps which means it remains within the tissue and reduces the chance of burning the grounding pad and safety concerns for medical equipment.
Mono Polar Technique
The method in mono polar, the generator transmits an alternating current to the electrode, which is connected to the sharp area of tissue within the surgical area. The current travels through the vascularized, moist tissue, and then exits via an evaporative pad.
This technique aids in cutting and coagulation of tissue. The electrode should be clean and the electrode’s tip cleaning is required in order to prevent sparks from arcing or fires during surgery. The patient’s grounding system should be inspected prior to using in order to ensure the biomedical safety protocol is followed in Pakistan’s operating theaters.
Bipolar Technique
In the bipolar method, the current is pushed between two electrodes in the forceps with bipolar configuration. Electrosurgical generators provide energy directly to the tips, and there is no dispersive pad required.
This technique is more suitable for wet field cautery as well as vascularized regions, specifically for electrosurgery in Ophthalmology. It results in less thermal burns and prevents the return of electrode burns, which makes it suitable for delicate procedures. It also lowers the risk of electrosurgery complications in high voltage surgical procedures.
ESU Waveform
An electrosurgical device (ESU) produces various electrical waveforms that use high frequency electricity to cut, and coagulate, or shrink tissues. The generator regulates the AC (AC) shape of the waveform, voltage, and frequency according to an electrosurgical process.
The electrical waveform may be continuous to ensure smooth cutting, or pulsed to control tissue coagulation. Each type of operation offers safe surgical energy, without causing thermal damage or electrical arcing leakage of electricity when operating room procedures and grounding protocols are adhered to.
Spark Gap Circuits
The older ESUs utilized spark gap circuits in order to produce the needed electrical waveform. These circuits created high frequency signals, by generating sparks between electrodes. These generated the heat needed for medical cauterization during the early stages of surgery.
Although they were useful but not always secure. Sparks could trigger sparks and arcing, which could lead to thermal or surgical fires destruction. Nowadays, medical equipment has shifted away from them due to safer options for electrosurgery for operating rooms across Pakistan.
Electronics Circuits for Electro Surgery “Solid State Circuit”
The latest electrosurgical unit principle (ESUs) make use of solid state circuits to provide more reliable electrical current. They replace spark based systems with semiconductors that control the electrosurgical generator in a more secure way and precisely when performing procedures.
Thanks to the solid state electronic the surgical handpiece is able to perform high frequency surgeries without interruptions. This helps prevent medical burns and improves the control of electrode tips and helps keep the surgical area dry and clean, decreasing the possibility of flammable substances that can cause fire in thermocautery or tissue dissection procedures.
How Does Electrosurgery Work?
Electrosurgery uses the high frequency of a flow of electricity to cut or shrink soft tissue after the procedure. The electrosurgical device (ESU) provides the controlled, alternating (AC) current (AC) by means of an electrode in order to efficiently perform surgical procedures inside the operating space.
This circuit of electricity includes the handpiece, generator, active electrode, and return electrode or dispersive pad. The electrosurgical generator helps keep the energy of the procedure stable while the patient’s returning pad and grounding aid in avoiding thermal injuries and prevent electrical burns.
Current Density
The term current density refers to the power of the electrical current that flows through the electrode’s tip. A small and sharp active electrode produces an extremely high density of current. This allows you to cut, burn or coagulate tissue by focusing high frequency surgical techniques.
When using wet field cautery, the moist tissue decreases the electrical resistance, allowing current to flow without risk. A well prepared skin, the use of conductive gel and careful placement of the grounding pad safeguard the patient from burns, sparks and arcing.
Current Waveforms
The ESU creates various electrical waveforms that are appropriate for each of the surgical functions. Continuous sine waves are used to cleanly cut tissue while a pulsed form is utilized for tissue coagulation. This helps to stop bleeding, without causing thermal damage.
The waveforms are created by the solid state system inside an electrosurgical machine. By changing the waveform, the surgeon can control how much heat is generated within the surgical area which reduces the risk of electrosurgery and enhancing the safety of operating rooms within hospitals all over Pakistan.
Tissue Effect
When electrosurgical energy touches tissues it produces heat because of an electrical impedance. The can be controlled to either cut, shrink, or coagulate the region. This specific procedure prevents deep burns and enhances medical cauterization.
In monopolar electrosurgery, the current is pumped from the active electrode across the patient and on to an electrode for dispersive. Bipolar electrosurgery is where the current is only flowing between bipolar forceps. This makes it more secure in flamable or vascularized areas. These techniques ensure surgical safety during delicate operations.
Types of Electrosurgical Technique
Electrosurgery utilizes various techniques to treat tissues by transferring high frequency energy throughout the human body. This Electrosurgical device (ESU) aids in cutting, and coagulate, or shrink tissue according to the method chosen. These methods increase the safety of surgical procedures and minimize thermal injuries.
Each method is unique by altering the electrical waveform electrode tip, the way the current is applied to the tissue. The active electrode, generator and dispersive pad need to be part of a single electrical circuit to be safe during the surgical room.
Electro surgical Coagulation
Electro surgical coagulation is a procedure where a a high frequency currents heat tissues until blood stops flowing. This technique is utilized for both monopolar electrosurgery and bipolar electrosurgery. It assists in preventing bleeding by clotting blood vessels, and reduces the risk of electrosurgery, such as burns from surgical procedures or leakage of current.
Tissue coagulation utilizes an alternating pulse (AC) to minimize severe thermal injury. A proper skin preparation as well as patient specific grounding and the placement of return pads are essential for preventing medical burns in this procedure. Pakistan hospitals.
Fulguration
Fulguration employs sparking and arcing between electrode’s tip and tissue to cause the surface to be burned. It drys out and kills undesirable tissue without any the need for deep penetration. It is employed in non vascularized areas to treat the growth of tumors on the surface.
The spark occurs by the current that jumps between the handpiece and the wet tissue of a field cautery. It causes a greater thermal burn to the skin, however it is not dangerous if medical equipment is operating according to guidelines and precautions for medical devices.
Desiccation
When desiccation is performed the electrode is positioned to touch tissues directly. The current of electricity flows through the sharp point, generating heat that dries and eliminates the moist tissue within. This can be utilized to kill cancerous cells or damaged ones.
Desiccation employs direct contact as well as the generator that regulates the current path. Dispersive and return electrodes have to function properly to avoid burning of the grounding pad or issues with electrical impedance. This method should be carried out using clean forceps and an electrode tip that is safe.
Electrotomy
Electrotomy is the process of cutting tissue with high voltage surgical. A continuous waveform is passed over an electrode with a monopolar configuration to create the heat needed to make a perfect surgical cut. This method is great for dissection of tissues for both laparoscopic and open procedures.
The surgical handpiece houses the active electrode that is moved over the tissue in an area that is dry and conductive. An effective placement of the pad for grounding and cleaning of the electrode’s tip can prevent flamable reactions and facilitate the smooth use of surgical instruments using electrical power within Pakistani operating room.
What is the difference between monopolar and bipolar electrosurgery?
It is the electrosurgical unit principle works by sending high frequency electric currents through the tissue. It employs two primary methods, monopolar electrosurgery as well as bipolar electrosurgery. Both techniques help cut or coagulate tissues with carefully controlled energy for surgery in a secure method.
The primary difference is the way that current flows. Monopolar electrodes transmit the patient’s current to an electrode that returns it, while bipolar forceps transfer the current through two tips without traversing the body. This can help prevent thermal burns and helps prevent medical burns.
Monopolar Electrosurgical
In monopolar electrosurgery the active electrode is placed on the tissue and the return pad’s placement completes an electrical circuit. The electrical current flows from the generator, then passes through the patient and leaves via an electrode that disperses.
This method is typically employed for large scale surgical fields, such as for coagulation or cutting of tissue. It requires an appropriate patient grounding system, a the electrode’s tip is clean, as well as the use of conductive gel in a safe manner to avoid burning the pads of the grounding sparking, arcing and arcing or leakage of current during high frequency surgical procedures.
Bipolar Electrosurgery
In bipolar electrosurgery forceps are used as both active as well as return electrodes. The current is only flowing between the tip of the surgical instrument therefore it isn’t able to traverse the entire body. This makes it more secure for areas with a high risk of vascularization.
This technique reduces the chance of electrosurgery dangers, and thermal injury. Surgeons utilize it in wet, moist fields of cauterization. It is extremely effective for medical cauterization. It is particularly effective for brain, eye or delicate electrosurgical techniques at Pakistani hospitals.
Dispersive Electrodes
Dispersive electrodes, often referred to as a return electrode effectively completes the electrical circuit used in monopolar electrosurgery. It’s a big pad that is placed on the patient’s body to transfer the AC (AC) in the Electrosurgical Generator, without burning.
The proper preparation of the skin and the proper placement of the grounding pad are essential for preventing electrical burns. The dispersive pad should cover a dry, clean conductory area to avoid thermal burns or fire hazards in operating rooms or medical equipment security problems during high voltage surgery.
What are the differences between cut and coagulation?
This electrosurgical unit principle works by delivering high frequency electricity through an electrode in order to treat or cut tissue. The cut mode produces an electrical waveform that aids in cutting tissue sharply with the least amount of pressure and damage.
In the coagulation state the electrical circuit makes use of an oscillating waveform. This results in slow heating which assists in sealing blood vessels, which reduces bleeding. This technique is often employed with a dispersive pad. This helps ensure better grounding for patients in the operating room.
Modes
The cut mode is developed to produce heat quickly that aids in the dissection of clean tissue. It employs a monopolar or bipolar forceps based on the site of surgery. The ESU creates focused energy for surgery to make precise incisions.
In the state of coagulation in coagulation mode, the current is less intense and the tissue is heated gradually. This reduces bleeding and reduces the risk of thermal injury to healthy tissues. Both procedures must adhere to strict operating room protocols to avoid electrical arcing leakage of current and surgical burns.
Waveforms
Different waveforms are utilized for cut and the coagulation. This cut form is smooth and continuous. It provides a smooth cut with less drag. This is the best waveform for areas that are dry and vascularized particularly when field cautery is performed in wet conditions.
The coagulation waveform is disrupted and slowed. This causes the electrical heat to be more uniform manner. This helps in sealing the vessels and preventing the risk of flamable or surgical fires. The surgeons select the waveform according to the electrosurgical procedure, as well as the electrode tip types.

The electrical current has to flow correctly across the circuit by using the proper dispersive pads and return pad positioning. This will prevent thermal burns as well as surgical burns. burning of the grounding pad in the operating room.
The generator’s high frequency energy can ignite materials that are flammable, therefore, proper operating room procedures should be adhered to. Skin preparation, proper electrode tip usage as well as avoiding arcing or sparks can reduce the risk of surgical fires and help prevent medical burns.
Complications
Unskillful handling of electrosurgical techniques could cause serious complications such as current leakage and electrical burns or injury to the blood vessels. In monopolar electrosurgery, inadequate cable grounding for the patient or damaged cables can result in thermal damage or unintentional tissue dissection.
Other potential complications include the risk of wet field cautery particularly during surgeries for the brain or eye. Poorly placed forceps, unclean return electrodes, or electrically conductive objects in close proximity to the electrode may increase the risk. The proper treatment for the handpiece used in surgery as well as electrosurgical generator help to avoid these incidents.
Risks of surgical smoke
In high frequency surgeries, the energy may generate the heat that causes it to release smoke from the procedure. The smoke can contain harmful particles which could cause breathing problems for patients. Smoke exposure for long periods of time can be harmful to lungs and increase the chance of developing diseases.
In Pakistan the operating rooms of Pakistan have no smoke evacuation systems for smoke evacuation. In the absence of control, electrosurgical procedure smoke could also cause a decrease in visibility which can lead to electrocautery error. It is crucial to safeguard the surgical area and minimize the risk of contamination in the operating room.
Minimizing risk of surgical smoke
