Procedure Planning Interface for Navigating Anatomical Passageways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing minimally invasive medical procedures lack intuitive graphical user interfaces for planning and navigating medical instruments through complex anatomical passageways, complicating the management of degrees of freedom and potential hazards.
Innovation Solution
A graphical user interface that supports intuitive planning of medical procedures by displaying image data, allowing users to define targets, trajectories, and hazards, and dynamically updating instrument positions based on user inputs, with features like hazard fences and interactive windows for path visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a graphical user interface is provided for planning medical procedures, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The graphical user interface is divided into multiple interactive windows, each displaying different renderings of anatomical passageways from various perspectives. This segmentation allows clinicians to plan procedures intuitively by interacting with separate, focused views rather than a single complex display, thereby improving ease of operation while managing system complexity through modular design
Solution Approach 2:
The system introduces a planning workstation as an intermediary device between the medical instruments and the clinician. This workstation provides the comprehensive graphical user interface and computational capabilities needed for procedure planning, separating the complexity of image processing and trajectory calculation from the actual surgical instruments, thus improving ease of operation without requiring the instruments themselves to be complex
2Loss of information
If multiple interactive windows displaying different renderings are provided, then information completeness is improved, but device complexity increases
Solution Approach 1:
The system displays multiple renderings of anatomical passageways across different interactive windows, each showing different perspectives or dimensional views of the same anatomy. This multi-dimensional presentation approach provides comprehensive spatial information and contextual data without requiring a single overly complex display, as each window focuses on specific aspects of the anatomy
3Measurement precision
If dynamic updating of instrument positions is implemented, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The graphical user interface automatically updates instrument positions based on control point movements without requiring continuous manual intervention or complex real-time calculations. The system maintains precision by updating displays dynamically when control points are moved, while energy efficiency is improved by using efficient rendering techniques and updating only necessary portions of the display

AI summary
A planning workstation includes a display system and a user input device and is configured to display a plurality of interactive windows for a user to view a plan for a medical procedure. Each of the plurality of interactive windows displays a different rendering of a model of anatomical passageways. The planning workstation is further configured to display a path through the anatomical passageways to a target of the medical procedure, display a virtual image of an instrument within the anatomical passageways, display a control point corresponding to a distal end of the instrument, receive a user input via the user input device, identify a position of the control point based at least on the user input, and, in response to receiving the user input, dynamically update a position of the instrument in at least one of the interactive windows to match the position of the control point.
