3D Kidney Surface Grid Planning for Precise Lesion Resection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nephron sparing surgery (NSS) planning tools lack a 3D visualization system tailored for precise lesion removal, relying on inefficient 2D cross-sectional slices, which hinders surgeons' ability to intuitively plan the best approaching angle and entry point due to inadequate spatial relationship understanding.
Innovation Solution
A 3D planning tool that automatically overlays a grid on the kidney surface, allowing interactive adjustment of a graphical tool like a cylinder around the lesion, calculating key measurements for intuitive surgical planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 2D cross-sectional slices from CT are used for surgical planning, then the existing tools can be utilized, but the surgeon cannot intuitively see the full picture and 3D spatial relationships among anatomic structures
Solution Approach 1:
The patent transforms 2D cross-sectional CT slices into a 3D virtual space model of the kidney, enabling surgeons to visualize the full 3D spatial relationships among anatomic structures, lesion locations, and surrounding tissues. This dimensional transition allows intuitive planning of approaching angles and entry points that cannot be achieved with 2D slices alone.
2Adaptability or versatility
If general 3D visualization workstations are used, then 3D structures can be visualized, but none are tailored to NSS procedure requirements
Solution Approach 1:
The patent creates a specialized 3D visualization tool specifically tailored for nephron sparing surgery by overlaying procedure-specific information such as grid systems on the kidney surface, lesion projections, and measurement tools. This localized customization provides NSS-specific functionality without requiring complete redesign of general 3D visualization workstations.
3Manufacturing precision
If a cylindrical graphical tool is placed around the lesion to define resection margins, then the treatment area can be visualized, but multiple parameter measurements are required to be displayed
Solution Approach 1:
The patent combines multiple measurement parameters (lesion size, depth from kidney surface, distance to vascular structures, resection margins) into a single integrated 3D visualization interface. The cylindrical graphical tool surrounding the lesion automatically displays all relevant parameters in one unified view, eliminating the need for separate measurements and simplifying the planning process.

AI summary
The present disclosure relates to a system and method of providing surgical assistance. The method includes obtaining a 3D space including an organ and a lesion located within the organ. Based on a shape of the organ, a grid is overlaid on a surface of the organ. The lesion is projected at a first location on an overlaid grid. A graphical tool disposed in a first orientation is positioned at the first location in the 3D space, and a plurality of parameter values of the lesion corresponding to the first orientation of the graphical tool are displayed in the 3D space. The graphical tool is manipulated to be disposed in a second orientation at a second location on the overlaid grid, and the plurality of parameter values of the lesion corresponding to the second orientation of the graphical tool are displayed in the 3D space.
