Access to All Data at the Click of a Button

Document management: software facilitates video management and image documentation during surgery
Access to All Data at the Click of a Button

Digital photos and videos play an ever increasing role in daily modern surgery. But controlling the different devices can be a very complicated and time-consuming process. New control software combines all image input signals and monitors regardless of manufacturer.

Videos and digital images are becoming more and more common in modern operating rooms as a way to provide support during the intervention and to document the procedure. So far surgical imaging modalities and related playback devices have been usually controlled manually via buttons, which can quickly become confusing with a growing number of systems, not to mention hygienic concerns. Even special software for the various devices is of little help here since each system runs only with its own program.

Caliop is designed as consciously open control software and is equipped with all required interfaces, allowing it to communicate with video input and output signals from any manufacturer under a uniform interface. It gives the operator, usually an operative nurse, an overview of all systems on one monitor and the ability to use the mouse or, if the display allows, touch screen entry to start and stop recording and to send the images to various screens in the room at the instruction of the surgeon. The program can even incorporate operating buttons from third-party devices so that the surgeon can push the button on the endoscope to record images and sequences.
All videos and images are cached in the system which gives the doctor a chance to examine the images again before either deleting them or storing them in the patient’s record. Also, the software can be linked to the hospital and radiology information system (HIS/RIS) and with the picture archiving and communication system (PACS), which can be used to retrieve patient data for the intervention and to store recorded images reliably in the patient’s record. The nurse will select the patient from a worklist at the beginning of the intervention and will have immediate access to all relevant information. At the same time, the system will automatically link all recordings with the patient once the patient is selected so as to prevent images or videos from ending up in the wrong place. To meet the required transmission standards, Caliop is DICOM compliant, which means that it fulfills the Digital Imaging and Communications in Medicine standard. It also allows for live streaming of the surgery, which can be used for educational purposes.
Furthermore, the software has a timer and countdown module that can be used to monitor the time it takes for medical cement to harden or the length of time a tourniquet is applied. While the user is working in the program, this timer and a visual time bar are clearly visible in the task bar at the bottom of the screen and will issue a reminder at the set time. This bar can also be used to carry out other functions, such as easy management up to eight parallel images from different devices. A click of the button will take the user to a preview screen or will allow the user to switch between windows.
During development an emphasis was placed in general on making a device that is as easy to use as possible. All menus are self-explanatory in their names and symbols, and subcategories can be expanded or minimized depending on selection, which keeps the interface as cleaned up as possible.
The system also has a modular design, allowing users to hide unused functions all together, which also makes the navigation slimmer. For the same purpose, registered users can also store frequently used functions in a dashboard on the start page; these functions will be opened directly at log-in and make the processes go faster. “The objective is to centralize and optimize the entire surgical workflow. This is why modules with note functions and advanced control of building services engineering are already in the planning stage,” explains Matthias Lubkowitz, Vice President OR Solutions at Eizo GmbH in Plauen, Germany.
Caliop can also be adopted to meet optical and design preferences and was developed with user friendliness in mind. Its features include different colors for entry and results fields, operating elements that are located in the lower area of the monitor for easier accessibility, and all entry areas arranged at the same height so that users do not have to move the mouse or their finger very far. The project team even examined finger sizes and pressure types for the touch functions to ensure reliable recognition of the respective field. Touch mode should not be used on small displays since the size of the display does not always allow entries to be made clearly.
The software is designed as a standard interface for Eizo’s CuratOR system for imaging and image reproduction in the field of medicine, but can also be used in the IT environments of other suppliers without problems. “In this respect, Caliop is also manufacturer-independent and can be used as a stand-alone system,” explains Lubkowitz. The program is compatible with Windows operating systems Windows 7 and higher and with Java version 8 and higher. Caliop is already in beta testing in the first reference medical centers. The video management and documentation software will be officially introduced in Europe at the Medica trade fair in Düsseldorf, along with three new standard configurations for the Surgical Panels, Eizo’s medical display consoles. su
