Integrated Skin-Mounted Device for Image-Guided Surgery Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image-guided surgery systems require multiple devices for registration, dynamic referencing, and imaging, which can be cumbersome and time-consuming, and often require manual initial estimates for accurate registration, leading to difficulties in hand-eye coordination and instrument manipulation due to arbitrary placement of dynamic references.
Innovation Solution
An integrated skin-mounted multifunction device that combines multiple functions, including registration, dynamic referencing, and imaging, using a circuit board with embedded position indicating elements, fiducial marks, and imageable patterns, and an integrated monitor for physiological parameter measurement, allowing for a single device to replace multiple independent devices and improve accuracy and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent devices are used for registration, dynamic referencing, and imaging, then each function can be performed with dedicated equipment, but device complexity and clutter increase significantly
Solution Approach 1:
The patent combines registration markers, dynamic reference markers, and imaging targets into a single integrated skin-mounted device. This merging eliminates the need for multiple separate devices while maintaining all required functions for image-guided surgery, directly resolving the contradiction between functional completeness and device complexity.
Solution Approach 2:
The integrated device serves multiple functions simultaneously: it provides registration markers for coordinate system alignment, dynamic reference markers for real-time positioning, and imaging targets for visualization. This multi-functionality allows a single device to replace multiple specialized devices, reducing clutter while maintaining reliability.
2Measurement precision
If manual initial estimates are used for registration, then registration can be performed, but time consumption and potential for error increase
Solution Approach 1:
The integrated device comes pre-configured with registration markers, dynamic reference markers, and imaging targets in precise geometric relationships before the surgical procedure. This preliminary preparation eliminates the need for manual initial estimates during surgery, enabling automatic registration that is both faster and more accurate.
Solution Approach 2:
The device enables automatic registration by providing all necessary markers and targets that can be automatically detected and processed by the image-guided surgery system. This self-service capability eliminates the need for manual intervention in the registration process, reducing both time consumption and potential for human error.
3Reliability
If dynamic references are placed arbitrarily, then dynamic referencing can be established, but hand-eye coordination and instrument manipulation become difficult
Solution Approach 1:
The integrated device uses asymmetric geometric patterns for the imaging targets and reference markers that provide unique orientation information. This asymmetry enables the system to determine the precise orientation of the skin surface, allowing dynamic references to be placed in anatomically meaningful locations rather than arbitrarily, thereby improving hand-eye coordination.
Solution Approach 2:
The device incorporates three-dimensional geometric patterns and markers that provide orientation information in multiple dimensions. This dimensional enrichment allows the system to accurately determine both position and orientation of the skin surface, enabling intuitive hand-eye coordination and instrument manipulation by providing comprehensive spatial reference information.
