Diathermy instruments for electrosurgical applications

What is diathermy?

Diathermy is a surgical technique that uses high-frequency electric current to cut, coagulate or destroy tissue. It is widely used in various medical disciplines, such as general surgery, gynaecology, dermatology and ENT. Diathermy is known for its precision and minimal blood loss, making it an efficient and safe method in both open and laparoscopic procedures.

How does diathermy work?

In diathermy, electrical energy is conducted through an electrode to the tissue, where it is converted into heat. This heat causes controlled cutting or coagulation of tissue. There are two main forms:

• Monopolar diathermy: current flows from the active electrode through the body to a neutral plate
• Bipolar diathermy: current flows between two points on the instrument, without the body itself conducting current

Bipolar diathermy

Bipolar diathermy works with two electrodes located in the same instrument. The current flows exclusively between these points, sparing surrounding tissue. This makes bipolar diathermy suitable for procedures requiring controlled coagulation and high precision, such as microsurgery and procedures in sensitive or moist tissue.
