Device Story

QEVO System consists of rigid endoscope and Endoscope Control Unit (ECU); captures internal surgical site images via rod lenses and CMOS sensor; transmits light via fiber optics from integrated LED source. System integrates with validated Zeiss host display devices (microscopes/monitors) for visualization. Used in OR by surgeons for general, neurological, and spinal procedures. Provides 2D visualization to assist surgical navigation and decision-making; benefits include enhanced visualization of internal anatomy during minimally invasive or open procedures.

Clinical Evidence

Bench testing only. No clinical data provided. Performance testing included optical safety (IEC 62471:2006) and biocompatibility (ISO 10993) for the insertion tube.

Technological Characteristics

Rigid endoscope with 45° view, 100° FOV, 5-30mm depth of field. 2MP CMOS sensor, 642 TV lines resolution. Integrated LED light source. Reusable; manual/automated cleaning and sterilization. Electrical safety: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-18.

Indications for Use

Indicated for patients undergoing general, neurological (ventricles/brain structures), or spinal (nucleotomy, discectomy, foraminotomy) surgical procedures requiring visualization of internal surgical sites.

Regulatory Classification

Identification

A neurological endoscope is an instrument with a light source used to view the inside of the ventricles of the brain.

#### 7. SUMMARY OF STUDIES

### Sterilization and Shelf Life

The QEVO endoscope is used sterile but is not provided sterilized before first use. It must also be end user cleaned and sterilized between uses. The reprocessing instructions have not been modified and are identical to the predicate device.

## Biocompatibility

The only patient contacting component of the subject device is the Insertion tube. The contact category for this component is Tissue/Bone/Dentin Communicating, < 24 hours. The materials were testing in accordance with ISO 10993.

## Performance Testing - Bench

There have been no changes in the System Requirements and Verification since the predicate. The following performance testing was provided, to support the substantial equivalence of the subject device:

- . Optical Safety - The QEVO Endoscope and ECU were assessed for conformity with the relevant requirements of IEC 62471:2006: Photobiological safety of lamps and lamp systems and were found to comply.
The determination of substantial equivalence was not based on an assessment of performance data.

#### 8. CONCLUSION

The OEVO System and the predicate device are both intended to be used for viewing internal surgical sites during surgical procedures. The indications for use are identical to those of the predicate device with an exception, that the subject device isn't intended to be used with a specific model of surgical microscope.

The technological characteristics and risk profile of the subject device is identical to the predicate device; and therefore, are identical in their relationship to safety and effectiveness.

Testing methods are identical to those of the predicate device; are identical in their relationship to safety and effectiveness.

Therefore, the subject device meets the requirements for substantial equivalence to the predicate device.
