headline-marker OR.NET

Project description

OR.NET is a collaborative project funded by the BMBF program “ICT 2020 – Research for Innovation”. The goal of the initiative is to develop basic concepts for safe dynamic networking of medical devices within the operating room. Especially the automatic dynamic networking of computerized medical devices and the interaction of these devices with medically approved software is of particular interest in the medical technology domain. The close cooperation between manufacturers, clinical operators, academia and regulatory bodies facilitates new ways of designing software architectures for the future hospital. The focus is on IT in the operating room and the pre- and postoperative phases, which also connects systems for surgical planning, OR management, as well as diagnosis and treatment. A special focus is on networking, interoperability and the safe operation of the OR infrastructure. To conceptualize and define new standards, research is being conducted regarding risk analysis, safety, security, interoperability and IT infrastructure together with standards committees (VDE, DIN, DKE, IHE …).

Research goals

The overall goal of the OR.NET project is the integration of medical devices in the operating room based on standardized communication technologies. The overall goal is divided into the following sub-projects:

  • Networking of medical devices based on a SOA with the use of existing internet “standards” such as WSDL, SOAP, and XML Schema,
  • Transition of the developed OR.NET solutions into international standards,
  • Development of appropriate operating,
  • Design, evaluation and implementation of software components for the digital operating room,
  • Technologies developed during the project will be implemented in clinical demonstrators.

ICCAS sub-projects

The overall project OR.NET is conducted by 46 project partners. The developments at the ICCAS comprise the following topics:

  • Clinical and technological requirements analysis,
  • Integration of results from preliminary projects (e.g. smartOR) and support of clinical and industrial partners,
  • Definition of an IT-architecture for the integrated operating room,
  • Design, evaluation and implementation of software components for the digital operating room,
  • Development and implementation of communication interfaces for information systems, medical devices and communication gateways,
  • Participation in the definition of new standards for medical device interoperability,
  • Implementation of a demonstrator operating room in Leipzig,
  • Evaluation and validation of the overall concepts within the clinical environment.

Previous research results

Several requirement analyses have been carried out in collaboration with clinical partners. Multiple surgical interventions from neurosurgery and ENT have been identified as reference workflows for OR.NET. From these interventions technical requirements, regarding device integration and medical device interoperability, are being derived. Together with technical project partners several workshops have been conducted to define communication requirements for medical device integration using plug-and-play technologies. As a result, this leads to formal device abstractions that are being used to define an integration-architecture with appropriate interface technologies.

Cooperation partners

A total of 57 partners from research and industry under the leadership of the University Hospital Heidelberg, Munich Technical University and RWTH Aachen University are involved in this cooperation project.

headline-marker Surgery Planning Software for Vascular Prostheses Implantation

Project description

The project deals with the definition of requirements for surgical planning software, which will focus on the surgical use of stent grafts. Furthermore the feasibility of a physically based simulation model for the assessment of stent graft fixation and sealing potential are studied and requirements for a software module for analyzing the results in the medical environment will get defined. The writability of the resulting data is based primarily on existing standards. Required extensions are also included.

Main topics of the project

  • Implant selection in endovascular surgery
  • Integration of Finite Element Method (FEM) in a medical planning software
  • Human-Machine Interaction
  • Workflow analysis
  • Medical standards: DICOM

Problem

A common complication of endovascular aortic aneurysm exclusion is the slipping of the stent graft resulting in insufficient sealing of the vessel. This post-operative complication may be associated with the selection of the vascular implant in the compound. In particular the determination of the stent graft oversize for the fixation of the implant in the vessel is of crucial importance.

Research goals

  • Integration of FEM results in a medical scheduling software for better assessment of migration and leakage risk in endovascular aortic aneurysm exclusion
  • Support the physician in selecting a suitable vessel implant through the quantified assessment of stent graft properties in the implanted state
