Reliable data transmission and power supply for high-end endoscopes
Schölly Fiberoptic, a leading original equipment manufacturer (OEM) of 2D and 3D endoscopes and cameras, is a valued customer we supply with individually-configured components for an interface between their electronics and camera system. They have successfully used our three-part test solution for the transmission of high-quality images for years.
Endoscopes are camera systems that are just millimetres in diameter and allow deep insights into cavities. They are used for minimally invasive procedures, particularly in the medical field for well-known applications such as gastroscopies and colonoscopies,
but also in the technical sector. Advances in sensor technology and image processing - 3D images in HD resolution are now standard - continue to drive the #miniaturisation of endoscopes, so that the possibilities for interventions in living organisms are continually expanding.
High-quality data combined with easy handling
Schölly Fiberoptic GmbH has almost 50 years of experience with medical technology and industrial applications. Since 2015, the manufacturer has relied on our components for a detachable interface in camera systems for endoscopic visualisation. This connects the control unit via various camera heads and ensures a reliable connection for power supply, communication, and video signal transmission.
Peter Breul, application engineer at INGUN, explains the cooperation: "The contact was established at a trade show before the pandemic. At the request of the customer, we designed a customised solution with specific geometry, which was perfected by software simulation. The goal was to combine the best possible data transmission with durability and easy handling."
The customised solution, based on renowned products from our standard portfolio, consists of three components: a #spring-loaded test probe (GKS-151 307 076 A 0600), a #receptacle (KS-151 30) where the probe is installed and a contact terminal (KT-151 102 080 L-A) that is attached to the camera unit. The result is a plug-in connection between the electronic control system and the invasive part - the actual endoscope - at the tip of which is the camera lens.
"In order to avoid interfering effects and achieve a high signal quality, the test probe was designed with the help of an integrated ball bearing to forcibly deflect the individual components. The receptacle serves as a mechanical mount and electrical connection to enable easy replacement of the probe," explains Peter Breul.
Durable and reliable over years of use
To achieve a low-impedance and impedance-matched connection, the transmission path was kept as short and homogeneous as possible, which is also reflected in the differential #impedance achieved. In addition, the plastic sheathing was chosen by the customer to ensure the interface also withstands frequent disinfection.
