Marker-Based Navigation Flow Control in Image-Guided Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flow control methods in image-guided surgery are unreliable and distracting for users, as they often require manual interaction with non-sterilizable touch screens, diverting attention from the patient and operation field.
Innovation Solution
A data processing method that utilizes marker data and condition data to intelligently control the flow of navigation systems in image-guided surgery, allowing for situation-dependent and reliable control flow management by detecting the spatial arrangement and movement of marker devices, thereby reducing user distraction and improving surgical focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual interaction with touch screen is used for flow control, then ease of operation is improved, but reliability deteriorates due to surgeon distraction and inability to sterilize the interface
Solution Approach 1:
The navigation system automatically controls its own flow based on detected marker positions and predefined conditions, eliminating the need for manual surgeon interaction. The system serves itself by autonomously determining when to perform actions such as zooming, panning, or switching views based on the spatial arrangement of markers and their movements.
Solution Approach 2:
The patent replaces the mechanical touch screen interface with an automated detection and control system that uses optical or electromagnetic marker detection. This substitution eliminates the need for physical contact between the surgeon and control interface, thereby preventing distraction and allowing for sterilization of the surgical field.
2Ease of operation
If touch screen interface is provided for flow control, then ease of operation is improved, but loss of time occurs due to surgeon attention being diverted from patient
Solution Approach 1:
The navigation system autonomously manages its own operation flow by continuously monitoring marker positions and automatically executing appropriate actions based on predefined conditions, eliminating the need for surgeon intervention and associated time loss.
Solution Approach 2:
The system maintains continuous monitoring of marker positions and continuously adjusts the navigation display according to detected conditions, ensuring that the useful action of providing surgical guidance occurs without interruption or loss of time due to manual interaction.
3Reliability
If automated control based on marker positions is implemented, then reliability is improved by reducing distraction, but device complexity increases
Solution Approach 1:
The navigation system performs multiple functions including marker detection, condition evaluation, flow control decision-making, and display management within a single integrated system. This multi-functionality manages complexity by consolidating what would otherwise require separate systems for each function.
Solution Approach 2:
The patent combines the flow control logic, marker detection processing, and navigation display management into a unified automated system. By merging these functions into a single coordinated system rather than separate components, the overall device complexity is managed while achieving reliable automated control.

AI summary
The invention is in particular directed to a data processing method for use in computer- assisted surgery, comprising the following steps: a) providing marker data which describe a spatial arrangement of at least one marker device and/or a change in a relative spatial arrangement of at least two marker devices (5, 6, 7); b) providing condition data which describe a condition for the spatial arrangement of at least one marker device and/or a condition for the change in the relative spatial arrangement of the at least two marker devices (5, 6, 7); and c) controlling a control flow of the data processing method on the basis of the marker data and the condition data.
