Surgical Navigation System with Multi-Angle Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical navigation procedures are time-consuming and require multiple iterations of adjusting surgical tools and imaging devices to confirm proper placement, as clinicians rely on two-dimensional views from a single perspective, making it difficult to accurately position surgical tools relative to targets in three-dimensional anatomy.
Innovation Solution
A system that uses an imaging device, such as a CT or fluoroscope, to automatically capture video or images from multiple angles, allowing clinicians to visualize the surgical tool's position relative to the target tissue from various perspectives in real-time, enabling correction of the tool's trajectory without retracting it, and utilizing a computing device to display this information on a user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fluoroscopic imaging device is used to confirm surgical tool placement from a single perspective, then the placement can be visualized, but it requires multiple iterations of moving the fluoroscope and surgical tool to confirm proper positioning from multiple angles
Solution Approach 1:
The patent transitions from two-dimensional fluoroscopic imaging to three-dimensional visualization by acquiring images from multiple angles and reconstructing them into a 3D model. This allows clinicians to view surgical tool placement from multiple perspectives simultaneously, eliminating the need for repeated repositioning of the fluoroscope and surgical tool to assess positioning accuracy.
Solution Approach 2:
The system performs preliminary 3D reconstruction and multi-angle visualization before final tool placement confirmation. By pre-acquiring images from multiple angles and creating a comprehensive 3D model, the system enables clinicians to plan and confirm placement in advance, reducing the number of iterative adjustments needed during the procedure.
2Measurement precision
If multiple iterations of moving the surgical tool and fluoroscope are performed to confirm proper positioning, then accurate placement can be achieved, but the procedure becomes time-consuming
Solution Approach 1:
The system provides real-time 3D visual feedback by continuously acquiring images from multiple angles and updating the 3D model during tool navigation. This immediate multi-perspective feedback allows clinicians to assess tool positioning accuracy without repeated iterative movements, significantly improving procedure efficiency while maintaining high positioning accuracy.
Solution Approach 2:
The patent replaces the mechanical process of physically repositioning the fluoroscope and surgical tool multiple times with an automated imaging system that captures multiple angles and generates 3D visualizations computationally. This substitution eliminates the time-consuming manual iteration process while preserving the ability to assess positioning from multiple perspectives.
3Ease of operation
If a two-dimensional fluoroscopic view is used, then the surgical tool placement can be visualized from one perspective, but it is difficult to accurately determine three-dimensional positioning
Solution Approach 1:
The system acquires two-dimensional fluoroscopic images from multiple angles and reconstructs them into a three-dimensional model, enabling visualization of surgical tool placement in 3D space. This maintains the simplicity of 2D imaging while adding the critical third dimension needed for accurate spatial positioning assessment.
Solution Approach 2:
The patent merges multiple two-dimensional fluoroscopic images taken from different angles into a single integrated three-dimensional model. This combination preserves the simplicity and familiarity of 2D imaging while providing comprehensive 3D positioning information that enables accurate spatial assessment of tool placement.

Data Source
AI summary
A system and method for performing a navigation procedure including a surgical tool, an imaging device, and a computing device. The surgical tool is navigated to a target tissue located in a target area to perform a surgical procedure on the target tissue. The imaging device acquires image data of the target area while the surgical tool is being navigated to the target tissue by automatically traversing back and forth along a path relative to the target area and acquiring image data of the target area while traversing the path. The computing device receives the image data acquired by the imaging device and displays the image data such that the surgical tool can be navigated to the target tissue while simultaneously visualizing a position of the surgical tool relative to the target tissue from multiple perspectives relative to the target area.
