Indications for Use
HJY VisualNext™ Endoscopic Vision System is intended for viewing internal surgical sites during general surgical procedures and for use in visualization of structures within the brain during neurological surgical procedures as well as for viewing internal surgical sites during anterior and posterior spinal procedures, such as nucleotomy, discectomy, and foraminotomy.
Device Story
System captures internal surgical site images via rigid endoscope containing CMOS sensor and 2 LED lamps; transmits data via 5m BNC cable to Endoscope Control Unit (ECU) for processing; outputs video to external monitor. Used in OR by surgeons for visualization during general, neurological, and spinal surgeries. Images are recordable/markable for analysis. System is single-use; ECU is non-networked. Provides real-time visualization to assist surgical navigation and decision-making; benefits patient through minimally invasive access and improved site visibility.
Clinical Evidence
Bench testing only. Performance verified via goniometer, theodolite, and integrating sphere for FOV, DOV, magnification, distortion, intensity uniformity, SNR, sensitivity, DOF, and resolution. Image quality validated in live pig model (GLP/AAALACi) comparing subject device to cleared comparators across light/working distance variables. No significant difference (p=0.569) between aged/non-aged units.
Technological Characteristics
Rigid metal arthroscope with CMOS sensor and integrated LED illumination. Connectivity: 5m BNC cable to ECU; no intranet/internet. Standards: ISO 10993 (biocompatibility), IEC 60601-1, IEC 60601-1-2, IEC 60601-2-18 (electrical/EMC). Single-use endoscope. Adjustable light intensity.

Dear Dr. John Jiannyuh Chen:
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.
