What is Electrocautery Machine?
Electrocautery is a medical procedure that involves the use of an electrocautery machine. An electrocautery machine, also known as an electrosurgical unit (ESU), is a medical device that uses high-frequency electrical current to cut, coagulate, or remove tissue during surgical procedures. It is commonly used in various surgical specialities, including general surgery, dermatology, gynaecology, and plastic surgery.
Overview / Product Profile of Electrocautery Machine:
The electrocautery machine consists of several components, including a generator, a handpiece or electrode, and a grounding pad. The generator produces the electrical current, which is delivered to the handpiece through a cable. The handpiece or electrode is the part that comes into direct contact with the tissue and delivers the electrical energy. The grounding pad is placed on the patient's body to complete the electrical circuit and ensure safety during the procedure.
When the electrode comes into contact with the tissue, the electrical current causes heating, which can be used for different purposes. In cutting mode, the high-frequency current vaporizes the tissue, allowing precise incisions to be made. In coagulation mode, the current is used to control bleeding by sealing blood vessels. Electrocautery can also be used for tissue ablation, fulguration (destroying abnormal tissue), and desiccation (drying out tissue).
Electrocautery machines have different settings and modes that can be adjusted by the surgeon, depending on the specific needs of the procedure. These machines provide precise control and minimize blood loss during surgery, making them valuable tools in the operating room.

Uses of Electrocautery Machine:
1) Surgical Procedures: Electrocautery machines are extensively used in surgical settings for incisions, excisions, and tissue dissection. The electric current generated by the device heats the tissue, causing it to separate or coagulate, minimising bleeding during the procedure.
2) Hemostasis: Electrocautery machines are effective in achieving hemostasis, which is the control of bleeding. Surgeons can use the device to seal blood vessels, preventing excessive bleeding during surgery.
3) Tumor Removal: Electrocautery machines aid in the removal of tumors, both benign and malignant. Surgeons can use the device to excise tumors, minimizing bleeding and reducing the risk of complications.
4) Dermatology Procedures: In dermatology, electrocautery machines are utilised for various procedures, including the removal of skin tags, warts, moles, and other benign skin growths. The electrical current helps in cutting or burning off the targeted tissue.
5) Gynaecological Procedures: Electrocautery machines find applications in gynaecological surgeries and procedures. They can be used for procedures such as loop electrosurgical excision procedure (LEEP) to remove abnormal cervical tissue or for cauterization during hysterectomy.
6) Ophthalmic Surgeries: In ophthalmology, electrocautery machines are employed in procedures such as eyelid surgery (blepharoplasty) to cut and coagulate tissue. They can help achieve precise incisions and control bleeding in delicate eye surgeries.
7) Dental Procedures: Dentists may use electrocautery machines in oral and maxillofacial surgeries, such as gingivectomy (removal of gum tissue) or frenectomy (removal of a frenulum). The device assists in controlling bleeding and promoting healing.
8) Veterinary: Electrocautery machines have applications in veterinary surgeries and procedures, similar to those in human. They are used for tissue cutting, coagulation, and hemostasis during various veterinary surgical interventions.
Types of Electrocautery Machine:
Monopolar Electrocautery Machine:
This is the most widely used type of electrocautery machine. It consists of a handpiece with a single active electrode that is used to deliver electrical current to the surgical site. The current flows from the active electrode through the patient's body to a dispersive electrode, which is usually a large pad placed on the patient's skin away from the surgical site.
Bipolar Electrocautery Machine:
Bipolar electrocautery machines have two active electrodes in the handpiece. The electrical current flows only between these two electrodes, which are used to grasp and treat tissue. Since the current is localized between the active electrodes, bipolar cautery is often used for delicate procedures where precise control is required, such as neurosurgery and ophthalmic surgery.
Advanced Bipolar Vessel Sealing Systems:
These are specialised types of bipolar electrocautery machines designed specifically for sealing blood vessels during surgery. They use a combination of electrical energy and pressure to seal vessels without the need for traditional ligatures or clips. These systems are commonly used in laparoscopic procedures, such as minimally invasive surgeries.
Ultrasonic Scalpel:
Although not strictly an electrocautery machine, the ultrasonic scalpel deserves mention in this context. It uses ultrasonic vibrations to cut and coagulate tissue simultaneously. The high-frequency vibrations cause the cells to break apart, resulting in cutting and coagulation. Ultrasonic scalpels are often used in procedures where precision and minimal damage to surrounding tissue are important, such as in neurosurgery or delicate procedures in the liver or pancreas.
Precautions with Electrocautery Machine:
1) Training and Familiarity: Only trained medical professionals who are familiar with the operation of electrocautery machines should use them. Adequate training should be provided to understand the principles, settings, and safe operating procedures.
2) Maintenance and Inspection: Regular maintenance and inspection of the electrocautery machine should be conducted according to the manufacturer's guidelines. This helps identify any potential malfunctions or issues that may affect its safe operation.
3) Proper Grounding: Electrocautery machines should always be properly grounded to prevent electrical shocks. The grounding system should be checked before each use, and the machine should be connected to a grounded electrical outlet.
4) Appropriate Patient Preparation: Ensure the patient is prepared appropriately for the procedure. This may include cleaning the surgical site and applying a conductive gel or pad as necessary. Follow the manufacturer's instructions regarding patient preparation.
5) Adequate Staff Protection: Medical personnel involved in the procedure should wear appropriate personal protective equipment (PPE), including gloves, masks, and goggles, to protect themselves from potential hazards, such as aerosolised tissue particles or bodily fluids.
6) Safe Handling of Equipment: The electrocautery handpiece and accessories should be handled with care. Avoid bending or damaging the cords, and ensure proper insulation of the equipment to prevent electrical hazards.
7) Controlled Use of Energy: Carefully select the appropriate power settings for the procedure and use the electrocautery machine in a controlled manner. Avoid excessive power levels or prolonged activation, as this can lead to tissue damage or unintended thermal injuries.

9) Fire Safety: Electrocautery machines can generate heat, which poses a fire risk. Ensure that flammable substances, such as alcohol-based solutions or drapes, are kept away from the surgical site. Have appropriate fire extinguishing equipment readily available.
10) Post-Procedure Care: After the procedure, ensure that the electrocautery machine is turned off and properly stored. Clean and disinfect the handpiece and accessories according to recommended protocols.
History of Electrocautery Machine:
The history of electrocautery machines dates back to the early 19th century. The concept of using electrical current for surgical purposes was introduced by Luigi Galvani and Alessandro Volta, who conducted experiments on animal tissues and discovered the phenomenon of muscle contraction induced by electricity. Building upon this knowledge, various inventors and physicians began exploring the application of electricity in surgery.
In the mid-19th century, a significant development came from the French surgeon Jean-Baptiste Denys, who introduced the concept of "thermo-cautery" in 1846. He used a heated platinum wire to coagulate bleeding blood vessels during surgical procedures. However, this method had limitations due to the difficulty in controlling the heat and the risk of excessive tissue damage.
The real breakthrough in electrocautery came with the invention of the electric generator by William T. Bovie in the early 20th century. In 1926, Bovie developed the first practical electrocautery machine, known as the "Bovie Electrosurgical Generator." This machine utilized high-frequency alternating current (AC) to generate the electrical energy needed for cutting and coagulating tissues. Bovie's invention revolutionized surgical techniques by providing a safer and more efficient method for controlling bleeding during operations.
Over the years, electrocautery machines continued to evolve with advancements in technology. The introduction of bipolar electrocautery, where the electrical current flows between two electrodes in the surgical instrument, allowed for more precise and localized tissue treatment. Advanced bipolar vessel sealing systems were also developed, offering a specialized method for sealing blood vessels during surgery.
Today, electrocautery machines are widely used in various surgical specialties, including general surgery, gynaecology, urology, and orthopedics. They have become an integral tool in modern surgical practices, offering precise tissue cutting, coagulation, and cauterization capabilities.
