SpineSite Endoscope System

The HydroCision SpineSite System is a single-use endoscopic video camera system consisting of a sterile, disposable endoscope and a reusable video processing unit (VPU). It provides illumination, image processing, and digital documentation for endoscopic diagnostic and surgical procedures in spine applications, and can also be used as an accessory for microscopic surgery.

The SpineSite Endoscope has a 5.0 mm overall diameter with 400×400 pixel optical resolution, 120° field of view, 0° angle of view, and 5-50 mm depth of field with a 200 mm working length. It uses distal LED illumination and contains a working channel for micro instrumentation. The reusable VPU provides video processing via edge card connector with HDMI and USB output ports and 110V/12V power adapter. Key differences from the predicate include a larger overall diameter (5.0 mm vs. 1.9 mm scope with accessory sheath), single working length (200 mm vs. three lengths: 125/180/250 mm), and simpler VPU without audio or internet connectivity.

Biocompatibility per ISO 10993-1; electrical and thermal safety per IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-18; human factors and usability per IEC 60601-1-6; electromagnetic compatibility per IEC 60601-1-2; design verification/validation to mechanical and optical specifications; and software validation.

Both devices employ the same fundamental architecture: a single-use, disposable endoscope with LED illumination and video sensor connected via edge card connector to a reusable video processing unit. Both use EO sterilization, biocompatible materials, and comply with identical electrical safety standards (IEC 60601 series). The SpineSite System's indications for spine procedures represent a subset of the cleared predicate's indications, meaning it will not raise new safety or efficacy issues. While the SpineSite has a larger diameter, single working length, and simplified VPU connectivity, these are minor design differences that do not alter the underlying technology, intended use as an illuminated camera system, or safety profile.
