3D Surgical Clip Positioning System for Minimally Invasive Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical display systems are inadequate for effectively visualizing and controlling three-dimensional surgical imagery during minimally invasive surgeries, leading to potential human errors in selecting optimal surgical clip positions due to occlusion and judgment errors, and they often require cumbersome wearable devices that are difficult to manage in sterile environments.
Innovation Solution
A system and method that utilize a three-dimensional model of a patient's anatomy, derived from CT scans, to automatically determine optimal surgical clip positions based on maximizing the removal of marked tissue while minimizing the removal of healthy tissue, using a processor to select positions with the highest ratio of mass to healthy tissue, and presenting this information on a display without the need for additional user input beyond initial selection criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surgical display systems are used to visualize surgical imagery, then the system is simple and easy to operate, but human errors occur in selecting optimal surgical clip positions due to occlusion and judgment errors
Solution Approach 1:
The patent transitions from two-dimensional surgical displays to three-dimensional visualization of surgical anatomy and clip positions. The system renders 3D models of blood vessels, masses, and surgical clips from CT scan data, allowing surgeons to view anatomical structures and clip placements from multiple angles and depths, thereby eliminating occlusion problems inherent in 2D displays and improving positional accuracy.
2Reliability
If manual inspection is used to determine surgical clip positions, then the system is simple to operate, but potential clip candidates may be missed leading to human error
Solution Approach 1:
The system performs automated identification and evaluation of optimal surgical clip positions through computer algorithms that analyze 3D anatomical models. The processing device automatically calculates which clip positions will maximize mass removal while minimizing healthy tissue removal, eliminating the need for manual inspection and reducing human error while maintaining ease of use through automated decision-support.
3Manufacturing precision
If optimal surgical clip placement is determined through automated analysis, then the precision of tissue removal is maximized, but the complexity of the system increases
Solution Approach 1:
The system performs preliminary 3D modeling and analysis of anatomical structures from CT scan data before the actual surgical procedure. By pre-calculating optimal clip positions and visualizing them in 3D space, the system prepares precise surgical guidance in advance, allowing the actual surgery to proceed with high precision while the complexity is managed through pre-processing rather than real-time computation.

AI summary
A system includes a display, and a processor. The processor may be configured to obtain a three-dimensional model of a patient including one or more blood vessels and a mass that is marked for removal, determine a position of each of one or more surgical clips within the three-dimensional model, where blood flow is restricted from a region of the three-dimensional model based on the one or more blood vessels of the three-dimensional model and the position of each of the one or more surgical clips, and present, to the display, the three-dimensional model of the patient including a visual indication of the region and the mass.
