Solution Overview
Problem
Existing minimally invasive medical procedures face challenges in accurately navigating and updating the location of targets within patient anatomy due to limitations in integrating intraoperative image data with preoperative models, leading to potential inaccuracies and inefficiencies.
Innovation Solution
A medical system that includes a display system, an elongate device, and an imaging probe, with a control system that receives and processes intraoperative image data to update the target location using graphical user interfaces and virtual navigation views, allowing for precise registration and adjustment of the medical instrument's position and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If preoperative models are used for navigation, then procedural planning is improved, but accuracy is reduced due to anatomical changes during surgery
Solution Approach 1:
The system transitions from static preoperative models to dynamic intraoperative image guidance. The imaging probe continuously captures real-time anatomical data, allowing the navigation system to adapt to anatomical changes during surgery and update target location dynamically, thereby maintaining accuracy while preserving planning efficiency.
Solution Approach 2:
The system implements feedback by comparing preoperative model predictions with actual intraoperative imaging data. The imaging probe provides real-time feedback on anatomical structures and target location, allowing the system to correct deviations and update navigation information, thus resolving the accuracy problem while maintaining the planning framework.
2Measurement precision
If intraoperative imaging is integrated with preoperative models, then target location accuracy is improved, but system complexity increases
Solution Approach 1:
The imaging probe serves multiple functions: it captures anatomical images, identifies target structures, and provides spatial localization data. By making the probe multi-functional, the system reduces the need for separate dedicated devices for each function, thereby improving accuracy without proportionally increasing overall system complexity.
Solution Approach 2:
The system uses an intermediary processing layer that integrates preoperative model data with intraoperative imaging data. This intermediary layer reconciles the two data sources, matching anatomical landmarks and updating target location, thereby achieving high accuracy while managing integration complexity through a structured mediation process.
3Measurement precision
If real-time image data processing is implemented, then navigation accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary processing of imaging data by pre-identifying anatomical landmarks and target structures during probe insertion. By preparing and pre-processing data as it becomes available, rather than waiting for complete datasets, the system maintains high navigation accuracy while minimizing processing delays during critical surgical moments.
Solution Approach 2:
The system implements selective processing by skipping non-critical analysis steps and focusing only on essential target identification and localization. By rushing through the processing pipeline with prioritized algorithms that identify key features quickly, the system achieves high accuracy without excessive processing time, skipping unnecessary computational steps.
