Diathermy is a medical procedure that utilizes high-frequency electrical currents to generate heat within the body tissues, with the objective of producing therapeutic effects. The word "diathermy" is derived from the Greek language, where "dia" means through, and "therme" means heat. Diathermy Equipment can be used in a wide range of medical applications, including pain relief, tissue repair, and surgical procedures. In this article, we will explore the various types of diathermy equipment and their applications in healthcare.
The two main types of Diathermy Equipment are surgical diathermy and physiotherapy diathermy. Surgical diathermy is used to cut, coagulate, or vaporize tissues during surgical procedures. This type of diathermy equipment generates high-frequency alternating currents that can be delivered through a variety of devices, including handpieces, probes, and electrodes. Surgical diathermy can be either monopolar or bipolar. Monopolar diathermy involves a single active electrode placed on the patient's body, while the return electrode is located elsewhere on the body. In contrast, bipolar diathermy involves two active electrodes that are close together and deliver current between them, minimizing the risk of electrical current traveling through the patient's body. Physiotherapy diathermy, on the other hand, is used to produce therapeutic effects by heating up deep tissues within the body. This type of Diathermy Equipment can be either shortwave or microwave. Shortwave diathermy uses high-frequency electromagnetic waves that penetrate deeply into the body, while microwave diathermy uses lower-frequency electromagnetic waves that penetrate less deeply. Physiotherapy diathermy can be used to treat a wide range of conditions, including chronic pain, arthritis, and sports injuries. Surgical Diathermy Equipment Surgical Diathermy Equipment is used in a variety of surgical procedures to cut, coagulate, or vaporize tissues. The two main types of surgical diathermy are monopolar and bipolar. Monopolar diathermy involves a single active electrode that is placed on the patient's body, while the return electrode is located elsewhere on the body. This creates a circuit, and electrical current flows through the patient's body, generating heat that can be used to cut or coagulate tissues. Monopolar diathermy can be delivered through a variety of devices, including handpieces, probes, and electrodes. Bipolar diathermy, on the other hand, involves two active electrodes that are close together and deliver current between them. This minimizes the risk of electrical current traveling through the patient's body, as the current flows only between the two active electrodes. Bipolar diathermy is typically used in procedures where precision is required, such as in neurosurgery or ophthalmology.
