Cable modules deliver medical-grade imaging subsystem with miniLEDs

Reducing design complexity and cost, OmniVision Technologies, Inc. has introduced the integrated OVMed OCHSA and OCHTA cable modules for single-use endoscope and catheters. The fully integrated medical-grade imaging subsystems combine a small diameter camera module with upgraded OVMed cables and miniLED illumination for a complete medically-tested assembly.

The OCHSA cable module offers 800 × 800 pixel resolution with a high-speed MIPI digital interface for larger outer diameter endoscopes, such as the bronchoscope, thoracoscope, pleuroscope, mediastinoscope, duoendoscope, and aminoscope. The cable module is designed to handle both short and long distances and is customizable.

The OCHTA cable module integrates OmniVision’s new OH0TA image sensor with quadruple the resolution of its predecessor and provides wafer-level optics in a single compact assembly. Due to its small size, the OCHTA cable module enables endoscopic devices to reach deeper into the body for a wide range of procedures, said the company, including neuro, ophthalmic, ENT, cardiac, spinal, urology, gynecology, and arthroscopy procedures. The module can also be used in dental and veterinary applications.

The cable modules feature OmniVision’s CameraCubeChip wafer-level technology in a tiny 0.65 × 0.65-mm camera module, with 400 × 400 or 160 KPixel resolution for high quality image captures. They also feature the latest OVMed cables in a thin micro-coaxial form factor.

In addition, OmniVision said this is the first commercially-available integrated miniLED illumination, which provides precise brightness control for single-use endoscopy. It features a higher contrast ratio within a smaller local area for extremely small package sizes. This provides individual brightness and dimming control for multi-spectrum (RGB/IR) devices in surgical procedures, said the company.

OVMed cable modules are medical-grade components that undergo certification, qualification and testing, including testing for banned substances, sterilization, biocompatibility, workmanship, operational tests, and stress tests. This increases the likelihood and speed of FDA certification for medical device OEMs, said OmniVision.

Both cable modules are available for sampling now and are available in short (0.25 m to 3.0 m) or long (3 m to 5 m) configurations. The integrated miniLED illumination feature will be available in the first half of 2022.  An evaluation kit with a pretested OVMed image signal processor is available.

OmniVision will demonstrate the new products at several upcoming medical device shows: MD&M Minneapolis, Nov. 3-4, booth 1639; CompaMed, Nov. 15-18, booth 8BH33; MD&M East, Dec. 7-9, booth 828.
