Cautery Machine

Electrocautery involves the conduction of heat through a probe that is heated to a high temperature using a direct electrical current, similar to a soldering iron. This can be achieved by using direct current typically provided by dry cells in a penlight-type device.

The procedures that utilize an electrosurgical unit (ESU), a device that generates electricity to cut or manipulate tissue is Electrosurgery. Electrocautery is one form of electrosurgery, where an electrical current is directly applied to tissue. Fulguration is another type, which uses a spark to produce sufficient heat to destroy specific cells. Some electrosurgery methods involve transmitting an electrical current through the body to deliver treatments.

The heat produced by the cautery machine induces coagulation of the tissue, effectively halting bleeding and sealing the tissue. This technique is frequently employed in various surgical procedures to manage bleeding or remove tissue, including applications in dermatology, ophthalmology, and general surgery.

Types of Cautery Machines:

Cautery machines come in two main types: monopolar and bipolar. Monopolar machines use a single electrode to transmit electrical energy, while bipolar machines utilize two closely spaced electrodes to confine the electrical energy to the tissue between them.

Various types of cautery machines are available, including laser, radiofrequency, ultrasonic, and hyfrecator devices. The choice of cautery machine depends on the specific medical procedure and the preferences of the healthcare professional performing it.

• Monopolar Cautery: These machines use a single electrode to deliver energy; current returns through a patient's skin pad.
• Bipolar Cautery: These machines use two closely spaced electrodes to limit energy flow to the tissue between them, suitable for delicate procedures.
• Hyfrecator: A monopolar device utilizing high-frequency energy for tissue removal and cauterization.
• Laser Cautery: Utilizes focused light beams for cutting or vaporizing tissue, common in sensitive procedures like eye, ear, or throat surgeries.
• Radiofrequency Cautery: Employs radio waves to heat and destroy tissue, ideal for precise removal, such as brain or spinal cord procedures.
