A Method for the Context-Aware Assignment of Medical Device Functions to Input Devices in Integrated Operating Rooms

A proposal for communication of intraoperative contextual information via DICOM Unified Procedure Steps

“…Presentation of information to a user Visualization of procedure-related information [10] Visualization of pre-and intraoperative patient data [11] Integrate information on central monitors [1] Information visualization related to the current surgical phase [12] Visualization of the remaining surgical duration [1,10] Information visualization depending on a surgeon [1] Provide decision support based on the surgical case [1] Visualization of the position of team members and devices [13] Integrate the control mechanisms of surgical devices [14] Visualization of preoperative notes [15] Automatic execution of a service Use the remaining surgical duration for resource planning [16] React to derivations and update the surgical plan [13] Force the execution of obligatory safety checks [12] Block the use of active instruments on adjacent structures [17] Guide the surgical team through surgical interventions [11] Avoid wrong configurations or handling of devices [11] Automatic adaption of the environment, e.g. lightning [18] Tagging of context to information for later retrieval Add procedural and timing data to the surgical protocol [18] Usage of a surgical recorder with aligned device data [12] Collect data for quality control and success measurement [12]…”

“…An interface for providing intraoperative contextual information shall support the needs of CAS. In order to identify these needs, literature research on prototypical CAS and their supportive task in the OR was carried out, resulting in 10 papers describing the functional scope of intraoperative context-sensitive assistance systems [1,[10][11][12][13][14][15][16][17][18]. Thereby, 20 intra-and perioperative use cases could be identified whose functionality is based on contextual information.…”
