Building blocks for camera- based medical technology
Minimally invasive surgeries require high-quality imaging for accurate diagnosis and successful outcomes. ATL Technology’s PREVOYANCE®
line of camera control units, distal end camera
assemblies, and proximal end cable assemblies provide medical device engineers with the opportunity and ability to confidently design and develop camera-based medical devices without being a specialist in miniaturised camera technology.
T
he PREVOYANCE system is designed to provide engineers with the essential building blocks for the development of camera-based medical devices and the foundational components that are needed to support these devices throughout the entire product lifecycle.
Understanding the PREVOYANCE System
A. The camera control unit (CCU) The CCU processes the video signals that are captured by the camera head and converts them into a format which is then suitable for display on a monitor.
Key components of the CCU Image Signal Processing (ISP): This component processes the raw video signals from the camera. It involves amplifying the signal, noise reduction, and converting the analogue signal to a digital format.
Image Enhancement Features: The PREVOYANCE CCU comes equipped with various image enhancement features like automatic white balance, colour correction, and other enhancements to provide images of the highest quality. Display Output: The processed video signal is sent to a display monitor, either contained within the PREVOYANCE CCU, or incorporated into existing capital equipment. User Interface: The user interface can be manipulated and customised to allow surgeons to control various settings. Data Recording and Storage: ATL’s CCUs provide the ability to record each procedure, allowing the video feed to be saved for later review or documentation purposes.
B. The distal end camera assembly Positioned at the tip of the device, the distal end camera assembly provides real- time, high-resolution imaging of internal structures during medical procedures.
Key components of the distal end camera assembly Camera Sensor: The camera sensor is the core of the distal end assembly. The PREVOYANCE system utilises sensors with varying resolutions, the most common resolutions are 400x400 and 720x720. Wire: Without maintaining signal integrity and proper signal processing for the chosen wire, the camera sensor’s image quality will not reach its full potential. The PREVOYANCE distal end camera assembly incorporates micro wire defined and developed to maximise the camera sensor. Light Source: The distal end camera assembly includes LED lights at the distal end of the assembly that provide bright, consistent lighting. Another option is to have the illumination source located in the body of the device and run light through fibres to the distal end or tip of the device. Tip Housing: The camera sensor, LEDs, and working channel are encased in a durable tip housing that is designed to withstand the rigours of surgical procedures. The tip housing is designed to be as slim as possible to allow easy insertion and navigation within the body. Pull Through Board: This component allows for distal or proximal end assembly and ease of connectivity to the proximal end cable assembly during the manufacturing process. With the PREVOYANCE system, not only does the engineer not need to be an imaging expert, but this component also minimises

their need to be proficient with the soldering iron.
C. The proximal end cable assembly Designed to maintain signal integrity and minimise interference, the proximal end cable assembly ensures that high- quality images captured by the distal end camera are accurately relayed to the medical team in real-time.
Key components of the proximal end cable assembly AKURA Interconnect: The PREVOYANCE system incorporates ATL’s flagship connector, the AKURA connector. Wire: Utilising the signal integrity provided by the distal end camera assembly, the proximal end cable assembly is specifically designed with an appropriate wire gauge to maintain high image quality even at a distance from the camera sensor.
Interface to Pull Through Board: The proximal end cable assembly and distal end cable assembly are connected by a simple custom-designed connection using a soldering iron.
ATL’s PREVOYANCE system represents a transformative advancement in developing camera-based medical devices that can significantly accelerate time to market. It provides engineers with reliable building blocks and enables medical device companies to expedite their product development processes by utilising these pre-existing, high-quality components rather than developing similar systems from scratch. ●
