Radiofrequency Surgery ENT with the ATMOS RS 221: 2.2 MHz Cutting and Coagulation

What is the ATMOS RS 221?

The ATMOS RS 221 is a radiofrequency surgery unit with an operating frequency of 2.2 MHz. According to the manufacturer, this frequency concentrates energy locally, allowing fine incisions with minimal stress on adjacent tissue, less secondary bleeding and faster wound healing.

The compact unit measures 133 × 284 × 220 mm, so it fits on a shelf of an ENT workstation or a trolley. It belongs to the ATMOS ENT range, together with workstations, microscopes and the stroboscope; see the ATMOS brand page.

For a clinic, a unit of this size is easy to place next to the chair in an ENT room. Check that the power supply, foot or hand switch arrangement and cable lengths suit the room layout before you order.

Modes: Mono Cut, Mono Coag and Bipol Coag

Three modes are available. Mono Cut is for fine, tissue-sparing incisions, Mono Coag provides haemostasis with ball electrodes, and Bipol Coag produces controlled tissue dehydration, for example of the nasal turbinates and soft palate. An automatic function supports simple volume reduction.

Bipolar radiofrequency ENT techniques keep the current between two poles at the tip, which limits the path of the current, while monopolar modes need a neutral electrode. Your clinicians choose the mode for each procedure; as a buyer, check that the modes you need are available and that the controls are clear.

In practice, a radiofrequency unit is used in the outpatient or minor-procedure setting where a compact device with quick setup is an advantage. The physician decides which procedures are appropriate and the equipment buyer should ask the supplier for training on mode selection and electrode handling.

• Mono Cut: fine, tissue-sparing incisions.
• Mono Coag: haemostasis with ball electrodes.
• Bipol Coag: controlled dehydration of tissue.
• Automatic function for simple volume reduction.

Electrodes, reprocessing and running costs

A wide range of ENT electrodes is available, and most are reusable, typically for about 70 cycles according to the manufacturer. That affects running cost and sterile-processing workload, so ask which electrodes you need, how they should be cleaned and sterilised and how to track their cycle count.

As a radiofrequency turbinate reduction device or general ENT unit, the RS 221 needs the usual electrosurgical precautions: correct neutral electrode placement for monopolar use, inspected cables and insulation, and an approach to smoke control. For the last point, see our article on surgical smoke evacuation.

Keep a log of electrode cycles. Reusable electrodes should be inspected for wear, coating damage and bent tips at each use, and withdrawn when they no longer meet the manufacturer limits.

Radiofrequency vs laser in ENT: how to compare

Radiofrequency units and ENT lasers overlap in some procedures but they differ in tissue interaction, accessories, safety measures and cost of ownership. Lasers need laser-safety controls according to standards such as IEC 60825-1, while radiofrequency units use electrosurgical safety principles under IEC 60601-2-2.

Rather than choose on general claims, compare on your case mix: the procedures you perform, the electrodes or fibres needed, training, room requirements, maintenance and consumables. Our ENT laser guide discusses the laser side, so that you can decide for your department with both in view.

Finally, consider integration with the rest of the room: a treatment unit for suction and irrigation, a microscope or endoscope for visualisation and a smoke control solution. A single supplier for these elements simplifies service.
