A pattern catalogue of surgical interventions for computer-supported operation planning

Area of Science:

• Medical Technology
• Surgical Planning Systems

Background:

• Commercial systems often focus on single procedures, not the complete surgical intervention.
• Managing complex Cranio-Maxillo-Facial-Surgery requires a comprehensive approach.

Purpose of the Study:

• To present a new operation planning system for Cranio-Maxillo-Facial-Surgery.
• To develop a system that supports the entire surgical intervention, including preoperative planning and intraoperative execution.
• To enable management of complex operations regardless of intraoperative technical support levels.

Main Methods:

• Development of a course model for managing surgical interventions.
• Introduction of instruction graphs detailing activity attributes and context.
• Presentation of surgical scopes for selecting views based on medical/technical knowledge and abstraction levels.
• Demonstration of operation patterns representing expert knowledge.

Main Results:

• The developed system was evaluated in the Cranio-Maxillo-Facial-Surgery clinic at the University of Heidelberg.
• The system successfully supports surgeons in both preoperative planning and intraoperative execution phases.
• The course model facilitates the management of complex surgical interventions.

Conclusions:

• The new operation planning system offers a comprehensive solution for Cranio-Maxillo-Facial-Surgery.
• The system's flexibility accommodates various intraoperative technical support scenarios.
• The focus on a course model provides a structured approach to managing complex surgical interventions.
