What is a cautery machine

Cautery machines are used in ENT, ophthalmic, etc. surgery routinely for a variety of tasks to cut, freeze, dissect, fulgurate, isolate and shrink tissue.

At high frequencies such as 100 kHz to 5 MHz, alternating current at various voltages (200–10,000 volts) is passed through the tissue to generate heat.

It consists of a generator and a handpiece with one or more electrodes in an electrosurgical unit. The device can be controlled using the switch on the handpiece or the foot switch.

They produce different types of electrical waves. As these waves change, so do the associated tissue effects.

What is the working principle of cautery machine

The cautery machine uses high-frequency electrical energy to clot the bleeding or cut tissue. Preferential conduction of electrical energy by blood vessels allows coagulation.

It is important to remove pooled blood and irrigation fluid from the operative area which acts as an insulator or can dissipate the energy of the cautery, which can sometimes reduce its effectiveness.

It consists mainly of electrocautery, also known as thermal cautery, refers to a process in which a direct or alternating current is passed through a fine-resistance metal wire electrode, thereby releasing heat.

is generated. Hot electrodes are then applied to the living tissue to achieve varying degrees of hemostasis or tissue destruction.

Electrocautery can be used in various minor surgical procedures in dermatology, ophthalmology, nose ear larynx, otolaryngology, plastic surgery and urology.

In this process the current does not pass through the patient; Thus, the procedure can be used safely or has no harm in patients with implanted electrical devices such as cardiac pacemakers, implantable cardioverter-defibrillators, and deep-brain stimulators.

How to Work the Coterie Machine

First plug the system power cord into the Energy Platform’s panel receptacle and check for proper grounding.

Connect directly to AC power and try to avoid the maximum power strip or extension cord, let’s say, use it.

Turn on the ESU energy console and verify the self-test automatically. After the self-test is successfully completed. A green light appears on the screen.

Connect the footswitch correctly and check to work by activating after connecting to the machine. According to the machine model, unipolar/dipole footswitches vary.

Connect the neutral plate connector to the machine and check the connectivity then there is a green light on the control panel

Now connect the sterile monopolar or bipolar pencil provided by the scrub. Connect the machine end to the appropriate connection and check the values ​​of the Diathermy Endosurgical Unit are correct.

Surgeons can prioritize the setting of tissues and procedures.

Now check if it is working properly by activating the CUT and COAG buttons on the hand control/footswitch.

Beep sound and flashing light on control panel when activated indicates use of Endo Surgical Unit

Different machines have different modes like cutting and coagulation.

What are the types of electrocautery?

High-frequency electrosurgery can be referred to four different methods:
1.) Electrocoagulation.
2.) electrodesication.
3.)Electrofulguration.
4.) Electrosection.

These methods involve high-frequency alternating current, which is converted into heat by resistance when it passes through the tissue.

What is Bipolar cautery machine

Bipolar electrosurgery Both the active electrode and the return electrode can be used at the site of surgery. It consists of two tips that act as active and return electrodes.

Only the tissue held in forceps is included in the electrical circuit. Since the withdrawal function is performed by one end of the forceps, electrodes are not required to return the patient.

Bipolar cautery operates regardless of the medium in which it is used. This allows for coagulation in a liquid environment, a major advantage when attempting to coagulate in a wet area. As a result, bipolar electrosurgery is often referred to as ‘wet field’ cauterization.

What is the Monopolar cautery machine

Monopolar electrosurgery active electrodes are placed at the surgical site. Patient return electrodes, also called dispersive pads, are placed elsewhere on the patient’s body.

This current passes through the patient as it completes the circuit from the active electrode to the patient return electrode. The function of the return electrode is to safely remove the current from the patient.

If the heat generated over time is not dissipated safely by the shape or conductivity of the patient’s return electrode, a return electrode burn occurs.

What is Advantages or Benefits of the Cautery Machine

1.) The electrodes used in electrosurgery are easy to bend or use which help to lubricate the soft tissues.
2.) Electrodes can be cut at its edge and end which helps to cut soft tissues deeply.
3.) It has much faster cutting speed than other methods like diode laser.
4.) It is a painless method.
5.) If the electrode is cleaned during operation, it can produce consistent, faster and better results.
6.) In this the electrode tips can be changed into pencil shape which can cut narrowly and precisely.
7.) This is a cheaper method.
8.) These electrodes themselves are disinfected.
9.) It is used to help prevent blood loss during surgical operations.

What is Drawbacks or Disadvantages of the Cautery Machine

1.) The smell of burning flesh using electrosurgery is greater than with diode laser technology.
2.) The taste of burnt meat during surgery remains in the mouth for a long time.
3.) It is necessary for the patients to be anesthetized for the surgery.
4.) It is a very fast cutting method, if proper care is not taken by the doctors it can lead to excessive harvesting.
5.) High heat is generated during cutting and hence it is not used near implants. A diode laser is used near the implant.

What is the cost of Cautery machine

The cost of a cautery machine, however, varies according to the make and model. Mainly its price ranges from $ 225 to $ 8500. But its price varies with the city.
