“…The system idea is concretized by system goals (SG) depicted in Table 1 . The requirements for specifying these system goals were extracted from six published articles on prototypic CAS for surgery [ 1 , 7 , 13 , 21 , 23 , 26 ]. Integration of CAS in clinical routine is still pending [ 1 ].…”

“…System architectures for a context-aware OR already exist [ 21 – 23 ], but do not support loose coupling of unknown CAS and an SRS which is essential to allow vendor- and device-independent orchestrations. In this work, we specify and implement an SDC interface for the standardized communication between an intervention-independent SRS and unknown CAS to enable context-aware assistance in the OR (Fig.…”

Purpose Context awareness in the operating room (OR) is important to realize targeted assistance to support actors during surgery. A situation recognition system (SRS) is used to interpret intraoperative events and derive an intraoperative situation from these. To achieve a modular system architecture, it is desirable to de-couple the SRS from other system components. This leads to the need of an interface between such an SRS and context-aware systems (CAS). This work aims to provide an open standardized interface to enable loose coupling of the SRS with varying CAS to allow vendor-independent device orchestrations. Methods A requirements analysis investigated limiting factors that currently prevent the integration of CAS in today's ORs. These elicited requirements enabled the selection of a suitable base architecture. We examined how to specify this architecture with the constraints of an interoperability standard. The resulting middleware was integrated into a prototypic SRS and our system for intraoperative support, the OR-Pad, as exemplary CAS for evaluating whether our solution can enable context-aware assistance during simulated orthopedical interventions. Results The emerging Service-oriented Device Connectivity (SDC) standard series was selected to specify and implement a middleware for providing the interpreted contextual information while the SRS and CAS are loosely coupled. The results were verified within a proof of concept study using the OR-Pad demonstration scenario. The fulfillment of the CAS’ requirements to act context-aware, conformity to the SDC standard series, and the effort for integrating the middleware in individual systems were evaluated. The semantically unambiguous encoding of contextual information depends on the further standardization process of the SDC nomenclature. The discussion of the validity of these results proved the applicability and transferability of the middleware. Conclusion The specified and implemented SDC-based middleware shows the feasibility of loose coupling an SRS with unknown CAS to realize context-aware assistance in the OR.

“…For use cases like the activation of a wash flow, the OR integration system or the HF generator may use remote control functionalities of the pump to trigger the desired behaviour for a certain duration. Smart surgical pumps will additionally optimise their control algorithms by taking preoperative patient and procedure information into account or by consuming current vital signs of the patient [2].…”

“…These standards are more specific than the core series, yet independent of actual devices and clinical use cases. [2] Whereas the exchange architecture and protocol are specified in much detail, there remains freedom in applying the standard to modelling the network representation of realworld medical devices [3]. This is intended but only partly desired: If two functionally similar devices from different manufacturers differ greatly in their model structure, their data may still safely be interpreted by a communication partner.…”

To translate recent advances in medical device interoperability research into clinical practice, standards are being developed that specify precise requirements towards the network representation of particular medical devices connecting through ISO/IEEE 11073 SDC. The present contribution supplements this protocol standard with specific models for endoscopic camera systems, light sources, insufflators, and pumps. Through industry consensus, these new standards provide modular means to describe the devices' capabilities and modes of interaction in a service-oriented medical device communication architecture. This enables seamless data exchange and the potential for new assistive systems to support the caregiver. Clinical relevance-Interoperable medical devices in endoscopic surgery are going to improve the clinical workflow by facilitating smart communication and interaction between the components in the operating room. This allows for new functionality and improved usability; ultimately reducing the stress experienced by the staff and increasing patient safety. In addition, easy access to medical device data will yield highquality data sets for clinical research.
