Which device is commonly used for radiofrequency ablation?

The device commonly used for radiofrequency ablation is an electrosurgical generator. This instrument is specifically designed to create radiofrequency energy, which is then used to produce heat that ablates (destroys) tissue. During the procedure, the electrosurgical generator sends a controlled amount of radiofrequency current to an electrode that is placed in contact with the targeted tissue, effectively heating it to a temperature sufficient to destroy the unwanted cells.

Radiofrequency ablation is often utilized in various medical fields, such as cardiology for treating arrhythmias and oncology for destroying tumors. The precision and control offered by an electrosurgical generator make it an ideal choice for these delicate procedures, allowing medical professionals to effectively target specific areas while minimizing damage to surrounding tissues.

In contrast, the other devices listed are used for different types of procedures or modalities. For example, an ultrasonic scalpel utilizes high-frequency ultrasonic vibrations to cut tissue, while an endoscope is used for visualizing internal organs. A laser catheter employs laser energy for ablation but operates on a different principle than radiofrequency ablation.
