• Record ID: K223932
• Device Name: SafeAir combi (SFR-combi-US)
• Applicant: Lina Medical Aps
• Product Code: GEI · General, Plastic Surgery
• Decision Date: Apr 26, 2023
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 878.4400
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The SafeAir Combi is an electrosurgical generator containing an integrated surgical smoke evacuator. The unit is intended to deliver high frequency energy for cutting and/or coagulating tissues using monopolar and bipolar tools in surgical procedures. When used with an electrosurgical pencil capable of surgical smoke evacuation, the console is also intended to remove and filtrate smoke generated during electrosurgical procedures.

Device Story

SafeAir Combi is an electrosurgical generator with integrated smoke evacuation. It accepts inputs from monopolar or bipolar electrosurgical accessories and a neutral electrode; it is operated by healthcare professionals in hospitals/clinics via a dedicated footswitch and 7-inch LCD touchscreen. The device transforms electrical input into high-frequency (HF) energy for tissue cutting (Pure/Blend modes) and coagulation (Fulguration/Spray/Bipolar modes). Simultaneously, it provides smoke evacuation via an ULPA filter (99.999% efficiency at 0.1 microns). The device features 'Instant Response' technology to sense tissue resistance and adjust voltage for consistent effects. Output is delivered to the surgical site to achieve hemostasis or tissue division. Smoke evacuation benefits the patient and staff by removing potentially carcinogenic surgical plumes. The device performs power-on self-diagnostics and provides alarm conditions on the screen if malfunctions occur.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included electrical safety, electromagnetic compatibility, human factors, transportation simulation, and smoke evacuation functionality. Performance testing followed FDA guidance for electrosurgical devices, covering thermal effects on tissue, ESU performance, contact quality monitoring (CQM) functionality, and accessory compatibility. Results demonstrated the device meets specifications and performs equivalently to the predicate.

Technological Characteristics

Class I electrical protective class; 110-230V input. HF energy output (472 kHz). 5 output modes (2 cut, 2 coag, 1 bipolar). Integrated smoke evacuation with ULPA filter (SFR-FIL-C). 7-inch LCD touchscreen interface. Instant response technology for resistance sensing. Duty cycle 25% at max power. Dimensions 17x40x40 cm, 22 kg. Non-sterile.

Indications for Use

Indicated for use in surgical procedures requiring electrosurgical cutting and/or coagulation of tissues using monopolar and bipolar tools, and for the removal and filtration of surgical smoke when used with a compatible electrosurgical pencil. Intended for use by healthcare professionals in hospitals and clinics.

Regulatory Classification

Identification

Dear Scott Blood:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

From the comparison above, the subject device and predicate device have similar intended use, are both prescription use, and have the same operating principle. The differences in the devices have been assessed and do not raise new questions of safety or effectiveness.

## Non-clinical performance testing:

## Electrical Safety:

Electrical safety and electromagnetic compatibility testing were conducted in accordance with IEC 60601-1, IEC 60601-1-2 and IEC 60601-2-2 to demonstrate the basic safety, essential performance and emissions and immunity characteristics of the device. The testing demonstrated the appropriate electrical safety and electromagnetic compatibility profile for the device.

## Bench / Performance Testing:

Comparative performance testing included:

- Human factors testing
- Transportation simulation
- Smoke evacuation functionality
- Testing in accordance with FDA Guidance "Premarket Notification (510(k)) Submissions ● for Electrosurgical Devices for General Surgery"
- Thermal effects on tissue 0
- ESU performance O
- COM functionality ol
- Accessories compatibility O

The results demonstrated that the device performance was met and was substantially equivalent to the predicate device.

The subject device and predicate device are intended to deliver high frequency energy for cutting and/or coagulating tissues using monopolar and bipolar tools in surgical procedures. The smoke evacuation function is not a novel feature and there are several cleared devices already used in the US today. Smoke evacuation is recommended to be used in clinical procedures such as electrosurgery in which tissue smoke plume and aerosols can be generated due to concerns about potential carcinogenic effects.

The technological characteristics between the subject and predicate devices are in most cases identical, for those cases where they are similar or different, those differences have been properly tested and evaluated. Design Verification and Validation activities carried out on the SafeAir combi device confirms that device meets specification and performs as intended.

Based on above comparison and discussion, the SafeAir Combi is deemed as safe and effective as and substantially equivalent to the predicate device.
