Nachwuchsgruppe Chirurgische Assistenzsysteme

Die minimalinvasive Chirurgie, auch Schlüssellochchirurgie genannt, unterscheidet sich von der konventionellen durch eine Reduzierung des Patiententraumas und dem Einsatz spezieller Instrumente und Techniken. Ein minimalinvasiver Eingriff ist eine komplexe Operation, die den Chirurgen mit zusätzlichen Schwierigkeiten und Limitationen konfrontiert und große Geschicklichkeit, Präzision und Erfahrung erfordert. Immer häufiger kommen deswegen intraoperative Assistenzsysteme zum Einsatz, die auf eine Verbesserung der Operationsqualität und eine Minimierung der chirurgischen Belastung abzielen.

Immer komplexere Handhabungs- und Assistenzsysteme führen zunehmend zu einer Überforderung des Chirurgen. Wünschenswert ist daher eine kognitionsgesteuerte Assistenz, die bestimmte Tätigkeiten erkennt, die Interaktion mit den technischen Hilfsmitteln erleichtert und in Abhängigkeit des aktuellen Operationskontextes eine Unterstützung generiert.

Ein kontextbezogenes Assistenzsystem generiert bei Bedarf eine geeignete Unterstützung, die zu einem bestimmten Zeitpunkt benötigt wird und gleicht redundante und unzureichende Informationen aus. Um den aktuellen Operationskontext zu bestimmen und eine kontextbezogene Visualisierung zu ermöglichen, muss die aktuelle Operationssituation mithilfe intraoperativer Sensordaten analysiert und interpretiert werden. Zusätzlich erfordert die Einblendung präoperativer Daten in die Operationsszene die Berücksichtigung von instrumenten- und atmungsinduzierten Gewebedeformationen. Mithilfe eines aktuellen, intraoperativ gewonnenen Modells, das während der 3D-Analyse aus endoskopischen Bildsequenzen generiert wird, kann eine Registrierung mit präoperativen Daten erfolgen. Weiterhin werden a-priori Informationen über die physikalischen Eigenschaften des zu betrachtenden Gewebes (biomechanische Modellierung) genutzt, um diese Deformationen auszugleichen.
