Everything in Sight: Lung clinic improves workflow in the OR with solutions by EIZO.


From CT scans to endoscopy videos and electronic patient files, the conventional light box is no longer adequate when a doctor wants full access to all available information about a case. Many clinics still manage with PCs on mobile technology carts with the corresponding space and logistical difficulties, alongside hygiene issues. The LungenClinic Grosshansdorf (Lung Center Grosshansdorf) emphasizes great importance to sourcing an efficient and future-proof solution for their new thoracic surgery rooms and so installed special Surgical Panels by EIZO.

The EIZO system includes several high-resolution displays, some mounted on the walls and others suspended from the ceiling so that the movement of the OR team is not hindered. Integrated video management allows the surgeon flexible yet centralized control between any picture signal, both live recording or saved images, which can be easily switched between any of the displays according to needs. This allows the surgeon to concentrate fully on the patients’ care. In the near future streaming technology will allow live transmission directly from the OR for educational purposes.


Annually about 12,000 patients are treated at the LungenClinic Grosshansdorf, 7,000 of which are in-patients. Every year 1,000 to 1,100 lung surgeries are performed at the specialist clinic.


To ensure the best possible medical care for patients, according to the latest medical standards, the teaching hospital of the University in Lübeck opened a new functional wing in October 2014. It houses the central sterile supply department, an outpatient center, two operating rooms for thoracic surgery as well as corresponding preoperative and postoperative departments.


“It was our goal to create state-of-the-art ORs with modern communication technology fully meeting all current demands with regard to medical care and hygiene whilst also embedding a high level of future compatibility, thus making a sound investment” explains Wolfgang Gerckens, Commercial Director at the clinic.

The requirements regarding the technology, especially the image management aspects, were very high and included live transmission in HD-quality, an integrated audio system, the ability to shift between different screens, touch screen operation on one of the displays, and several different data inputs on another. “An important factor was also reliability. Large quantities of data are now collected for every patient and the physician treating the patient has to have access to that data at all times and that is why fallback routines were really important to ensure constant and reliable availability”, says Medical Technician Malte Sommer together with the Head of Medical Technology Mr. Puchert, who helped to draw up the system specifications.

Video Workstations for Different Requirement Profiles

The choice was made to invest in the concept offered by EIZO who provide a complete range of the latest state-of-the-art displays, video management, and data transfer technology which when combined with their Surgical Panels provides a comprehensive and flexible solution. Both ORs were equipped with several different displays and control systems for different purposes. The workstation for nurses was updated with a 23" display with an integrated PC, a lockable storage space, and a pivoting antimicrobial membrane keyboard to facilitate access to the hospital information system (KIS). A connected barcode scanner simplifies the tracking of consumable supplies. The main control unit is a panel with an integrated PC, a 47" monitor for high-resolution images and a 23" touch screen which allows access to the picture signal distribution and medical documentation software such as PACS. This station is also equipped with a pivoting and height-adjustable keyboard, which can adapt ergonomically to the user’s preferred working posture to ensure the highest possible comfort and efficiency. In addition, the keyboard features embedded pressure keys which can be used to switch the video signal in case of a breakdown of the internal PC system. The viewing options are complemented by a 47" grand display featuring different signal input options at the front.

Video Workstations for Different Requirement Profiles

All monitors utilize their highest potential with HD resolution, brightness of up to 700 cd/m2, and a contrast ratio of 3000:1 at 23" and 1000:1 at 47" screen diagonal.

The packaged unit consisting of a display and PC with a depth of only 10.5 cm and is implemented into the wall to conserve space. The outer surface is a flat case made from powder-coated sheet steel and anti-reflective single-pane safety glass which can be easily cleaned with all disinfectants officially approved by the Robert Koch Institute. Contamination is eliminated since there is no air exchange within the OR.

The monitors above the operating table can be adjusted freely. The adjacent anesthesia room is also equipped with a ceiling mounted supply unit and monitor. All equipment are free from the floor and there are no rolling carts or cluttering cables which facilitates both clean rooms and hygienic working.




Ergonomical Operating Thanks to Flexible Image Control

The core of the EIZO Surgical Panels is the video management technology lying behind the screen and the sophisticated transmission system. The central control of all image sources (MRI, CT, or digital X-ray images from the patient file) to live recordings of endoscopy, ultrasound, and surgical cameras and the display of vital parameters allows a comprehensive, adaptable, and flexible review of any relevant image or video. The system is specifically designed to be modality independent so it is compatible with different systems from various manufacturers and it can process digital and analog signals of all known formats. img09.jpgThanks to this “surgical cockpit” the doctor has access to all images exactly where he or she needs them. “From an ergonomic point of view this system is a quantum leap”, states Dr. Med. Christian Kugler, Chief Physician in the Department of Thoracic Surgery in Grosshansdorf. “Previously the viewing direction, the body, and operating axis didn’t line up. The surgeon had to crick his neck or walk directly in front of the monitor in order to view the screen. The new displays are much more comfortable and the viewing of the pictures is improved which in the end enhances the patient’s well-being.”


In addition the operating tables are also designed to meet the highest ergonomic standards. The surgeons at the Lung Center use the monitors primarily to display radiology diagnostics, endoscopic recordings, especially bronchoscopies as well as thoracoscopies which is a non-invasive method of exploration of the thoracic cavity. The surgeon may determine the image source and the image distribution on the displays. In case other images are needed later, the assisting nurse or the anesthesiologist can easily modify the settings. “Right now we mainly use the cinema setting which shows the images passing through in sequence”, says Dr. Kugler. Surgeons can also activate video sequences via a foot control with freely configurable functions.

Multi-Secured and Future-Oriented Technology

The significant criteria for the concept of image management to meet the high quality requirements in the OR was signal processing. Diagnostically relevant images cannot tolerate the compression loss of regular extenders. EIZO uses a special extender, originally developed for radiology purposes, which guarantees lossless transmission within 36 meters. All picture signals can be output in real-time and in Full HD quality (1080p60 or 3G-SDI). The processing of all connected image sources occurs internally and progressively to ensure the highest display quality using optical fiber cables. “This offers the advantage that even greater quantities of data, for example 4K or Ultra-HD images, can be handled effortlessly”, notes Matthias Lubkowitz, Vice President of EIZO GmbH. “Additionally the signals are always electrically isolated, so that there is no danger of electric shocks for staff or patients.” To ensure “failure-free” transmission, an extra optical fiber cable was installed in addition to the main line as well as a parallel copper line as an extra fail-safe solution. Reliability and sustainability were crucial factors when choosing highly durable components for the control devices and playback units. Doing so guarantees a long product lifecycle and replacement parts are readily available. Furthermore the entire system is modular and sits in a case system developed in-house so that each component can, if necessary, be replaced within 15 to 20 minutes. “That minimizes not just potential downtime but allows a system update if new interfaces become available and that update capacity ensures long-term use”, explains Medical Technician Malte Sommer.

Multi-Secured and Future-Oriented Technology

Future Plans: Teaching Via Video Stream

Since September 2014, EIZO’s Surgical Panels and video management technology has been in use at the LungenClinic Grosshansdorf.  The technology has proven itself in the OR to make everyday work easier. However, the extensive systems could also be used in the future for another purpose. An HD streaming module integrated in the consoles allows the transfer of recordings from the OR via TCP / IP over the Internet, which could thus be incorporated in a course for medical students. “Even now we can display images from a camera installed in the operating lamp on the big screen, for example, so that students can watch,” said Dr. Kugler. “The streaming of live images would be a feasible next step.”


The fact that the appropriate technology could be seamlessly integrated into the overall system was one of the reasons for the purchase of the EIZO system for the Lübeck University teaching hospital, as the commercial manager confirms: “The importance of such teaching methods will grow. With the new system, we are prepared for it.”
