Evaluation: Smith & Nephew Lens 4K Surgical Video System
March 9, 2021 | Evaluations & Guidance
Preview
- The Lens 4K Surgical Imaging System is a Native 4K surgical video system that provides 4K ultra-high-definition (UHD; 3840 pixels/line × 2160 lines/frame × 60 frames/sec) surgical video images. ("Native 4K" video is acquired with a 4K three-CMOS complementary metal-oxide-semiconductor image sensor module, and the image is maintained in 4K format throughout the video chain.)
The Lens 4K offers three image-enhancement options:
- The Enhancement feature (Figure 2) increases contrast and sharpens the appearance of lines and edges.
- The Chroma feature (Figure 3) adjusts the color saturation of the image to meet the preferences of the surgeon and the needs of the procedure.
- The Phase feature (Figure 4) adjusts the R/G/B color temperature (hue). Smith & Nephew states that this is useful in general surgeries for adjusting color when viewing tissues and vessels.
