Multiple Surgical Navigation Views for Instrument-Specific Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical navigation systems often provide suboptimal single navigation views when multiple medical instruments are used, especially if they are far apart or handled by different surgeons, limiting the ability to navigate each instrument effectively.
Innovation Solution
A method and system that utilize multiple navigation views, each based on a respective set comprising a medical instrument and a patient tracker with a fixed spatial relationship, allowing simultaneous display of these views to enhance navigation accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single navigation view is used to visualize multiple medical instruments, then the system complexity is reduced, but the navigational accuracy and usability for each instrument deteriorates
Solution Approach 1:
The patent divides the single navigation view into multiple separate navigation views, each dedicated to a specific medical instrument. This segmentation allows each instrument to have its own optimized visualization, improving navigational accuracy while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent transitions from a two-dimensional single view to a multi-dimensional display system where multiple views can be arranged in spatial configurations (e.g., grid layouts, cascading arrangements). This dimensional expansion enables simultaneous presentation of multiple instrument perspectives without overwhelming the user.
2Measurement precision
If multiple navigation views are displayed simultaneously, then the navigational accuracy for each instrument is improved, but the device complexity increases
Solution Approach 1:
The patent creates a universal navigation view template that can be replicated and customized for different instruments. Each navigation view uses the same functional structure and controls, allowing the system to handle multiple instruments with consistent interface patterns, thereby managing complexity through standardization.
Solution Approach 2:
The patent implements dynamic navigation views that can be adjusted, hidden, or reconfigured based on the current surgical context and user needs. The system can automatically activate or deactivate specific views based on which instruments are currently in use, adapting the display complexity to match the operational requirements.
3Ease of operation
If a single navigation view is used for multiple instruments handled by different surgeons, then the ease of operation is maintained, but the productivity and workflow efficiency deteriorates
Solution Approach 1:
The patent assigns specific navigation views to specific surgeons or instrument operators, allowing each user to have customized information tailored to their specific instrument and surgical task. This local customization improves workflow efficiency by presenting only the relevant information to each user, reducing cognitive load while maintaining ease of operation.
Solution Approach 2:
The patent implements real-time feedback mechanisms where each navigation view provides immediate visual feedback about the specific instrument's position and status. This targeted feedback enables surgeons to work more efficiently with their respective instruments without needing to constantly monitor a single consolidated view, improving overall surgical workflow.

AI summary
A method for supporting clinical personnel with multiple navigation views is provided. The method comprises; obtaining patient tracking information indicative of tracked poses of two or more patient trackers, each of the patient trackers having a fixed spatial relationship relative to one or more anatomical elements of a patient's body; obtaining instrument tracking information indicative of tracked poses of two or more medical instruments; and triggering, based on the patient tracking information and the instrument tracking information, simultaneous display of multiple navigation views, each of the navigation views being determined based on a respective set comprising (i) at least one of the medical instruments and (ii) at least one of the patient trackers, wherein the sets differ from one another in the at least one of the patient trackers. A system, a computer program and a carrier are also provided.
