Ulrich Swiss has developed the Kenus system using Cognex In-Sight 5400S vision systems where traceability and management of sterile surgical instruments are critical factors. The robust stainless steel housing allows the reader to be used in IP68-rated (NEMA 6P) sterile, hygiene-conscious environments. Each instrument is permanently marked with 2D Datamatrix code, just 0.8 x 1.6 mm and 100% reliable, containing the extensive information necessary to keep track of it. The matrix code is drilled into a recessed surface on even the smallest of instruments, making the code damage resistant. The data management functions allow staff to identify how often an instrument has been sterilised and used.
