3D Holographic Guidance for Precise Interventional Instrument Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-guided surgeries face challenges due to the use of two-dimensional displays that divert practitioners' focus from the patient, making it difficult to determine optimal instrument insertion angles and leading to confusion and errors in translating 3D patient anatomy from 2D data.
Innovation Solution
A holographic augmented reality system that integrates a tracked instrument, first and second image acquisition systems, and a computer system to provide a 3D visualization of patient data and instrument trajectory, allowing simultaneous viewing of operating data and patient anatomy, with holograms for guidance and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If two-dimensional displays are used to show intraoperative data and preoperative data, then the data can be displayed to the practitioner, but the practitioner's focus is shifted from the patient to the displays and additional stress is placed on the practitioner's neck
Solution Approach 1:
The patent transitions from two-dimensional displays to three-dimensional volumetric holographic displays. This dimensionality change allows surgical data, anatomical models, and instrument trajectories to be visualized in spatial depth, enabling practitioners to view critical information without shifting focus from the patient. The 3D holographic interface presents data in the same visual field as the surgical site, eliminating neck strain and maintaining continuous patient monitoring.
Solution Approach 2:
The patent introduces a holographic display system as an intermediary between the surgical field and the practitioner's vision. This intermediary projects virtual surgical plans, anatomical structures, and real-time instrument positions as holograms that coexist with the physical patient in shared three-dimensional space, allowing simultaneous viewing of both patient and data without physical display screens.
2Loss of information
If two-dimensional displays are used to show surgical data, then the data can be presented, but the practitioner must mentally translate the position and trajectory of instruments relative to the data, leading to confusion and errors
Solution Approach 1:
The patent employs three-dimensional volumetric holographic displays to represent surgical data, anatomical structures, and instrument trajectories in their true spatial relationships. This eliminates the mental translation required when viewing 2D representations, as practitioners directly observe the three-dimensional positions and orientations of instruments relative to anatomical targets, significantly reducing positioning errors and improving measurement precision.
Solution Approach 2:
The patent implements real-time feedback by continuously updating holographic representations of instrument positions and trajectories as instruments move during surgery. This dynamic feedback loop allows practitioners to immediately verify instrument placement accuracy and adjust trajectories in real-time, preventing confusion and errors that would arise from static or delayed 2D displays.
