Integration of Robotic Applications in Open and Safe Medical Device IT Networks Using IEEE 11073 SDC

Abstract

Modern operating rooms (OR) undergo a constant rise in the amount and complexity of technical systems. Due to a lack of inter-device communication and integration, each device works stand-alone resulting in redundant sensors, input devices, monitors and-last but not least-crowded ORs and error prone humanmachine-interaction. Therefore, various manufacturers such as Brainlab and Karl Storz provide proprietary integrated workstations. However, those "monolithic" solutions restrict the flexibility of the users and the clinical operators regarding integration of innovative third party devices.In view of this, the OR.NET initiative (www.ornet.org) strives to develop international open standards for secure dynamic networks of medical devices in ORs. In the scope of the OR.NET project, based on service oriented architecture (SOA), the SDC (Service-oriented Device Connectivity) approach is currently in the process of standardization under IEEE 11073 to link medical devices in the OR (short OR.NETwork). It paves the way to interoperability between various medical devices due to its independence of license holders.However, the SDC network does not suit real time (RT) requirements of a deterministic data transmission and low maximum latency, e.g. for robotic applications. This paper shows an approach to extend the secure dynamic OR by a real-time capable network to allow the integration of robotic systems. Exemplarily, this paper outlines an orthopaedic robotic system that is released by a universal configurable footswitch. This significantly extends the scope of applications for integrated ORs with the IEEE 11073 standard.

Design and validation of a medical robotic device system to control two collaborative robots for ultrasound-guided needle insertions

“…Currently, only a base set of devices (OR-tables, microscopes, etc.) are included in the SDC device network and real-time capability for full robotic integration still poses challenges ( Vossel et al, 2017 ; Schleer et al, 2019 ).…”

Integrating a Tracking Camera in the OR Using the IEEE 11073-SDC Communication Standard

“…Only for robotic applications the increased maximum latency and standard deviation of scenario three could lead to disturbances of the control algorithms. A real time add-on to the OR.NET-SDCstandard with a second parallel network in place, as proposed in (Vossel 2017) and (Pfeiffer 2018), could eliminate this issue. Another solution would be to use the same physical network but different channels for real time and non real time traffic as presented in (Cucinotta 2009).…”

“…In contrast to manual navigational tasks, also robotic applications using an OR.NET integrated tracking camera are imaginable (Vossel 2017). At the Chair of Medical Engineering, RWTH Aachen University, robotic systems are being developed with the tracking camera being an integral part of the control loop.…”
