Surgical Visual Guidance Orthogonal Trajectory Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical navigation systems overwhelm surgeons with multiple views, leading to user strain and potential suboptimal outcomes due to the need to constantly shift focus between different views to correct deviations in instrument placement during procedures like dental implantation, where precise alignment and depth are crucial.
Innovation Solution
An image-guided system that provides a unified, three-dimensional visual display with a graphical guidance indicator orthogonal to the planned trajectory, including an aiming ring, X mark, reticle, and depth indicator, allowing real-time visualization of the surgical instrument's position, orientation, and depth relative to the planned implant, with audible signals for depth progression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple views are displayed to show instrument position and orientation, then measurement precision is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple views (panoramic view, live camera view, and computer-generated comparative views showing displacement in buccal/lingual, mesial/distal directions and angular orientation) into a single integrated display. This merging allows the surgeon to see all relevant information simultaneously in one unified interface, eliminating the need to constantly shift focus between separate views while maintaining comprehensive measurement precision for instrument position and orientation.
2Measurement precision
If multiple views are displayed to show instrument position and orientation, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The display system merges multiple complex views into a single integrated screen showing panoramic view, live camera view, and computer-generated comparative views of instrument displacement in multiple directions and angular orientation. This consolidation reduces the number of separate display components needed while maintaining comprehensive measurement precision through a unified interface.

AI summary
A visual guidance system for use in a surgical procedure. The system includes an image processing unit programmed to receive a three-dimensional image of a surgical area, information on an instrument being used in the procedure, and a surgical plan including a planned trajectory that the instrument should follow. The image processing unit generates a derived representation of the surgical procedure depicting the movement of the instrument on the three-dimensional image. A graphical guidance indicator is disposed on the three-dimensional image with a center point of the graphical guidance indicator centered on the planned trajectory, the graphical guidance indicator being displayed orthogonal to the planned trajectory. The derived image and the graphical guidance indicator depict at least five degrees of freedom of motion of the instrument. The graphical guidance indicator is changed based on the movement of the instrument in accordance with the surgical plan.
