Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical imaging systems struggle to recognize and convey concealed structures and dimensions within a three-dimensional space, leading to incomplete views and uncertain decision-making during surgical procedures.
Innovation Solution
A surgical system with dual scope devices and instruments for insufflating separate anatomical spaces, combined with advanced imaging and distance sensing, provides enhanced visualization and control, allowing real-time identification and avoidance of critical structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single insufflation system is used for both extraluminal and intraluminal spaces, then device complexity is reduced, but measurement precision and control accuracy deteriorate because independent pressure control is lost
Solution Approach 1:
The insufflation system is segmented into two independent subsystems: a first insufflation system for the extraluminal space and a second insufflation system for the intraluminal space. Each system has its own insufflation port, flow control, and pressure monitoring capabilities, allowing independent pressure regulation and eliminating cross-contamination between spaces.
Solution Approach 2:
A sealing port with sealing element acts as an intermediary at the tissue wall interface, allowing the endoscope to pass through while maintaining pressure separation between the two spaces. The sealing element creates a barrier that prevents gas flow between extraluminal and intraluminal spaces, enabling independent insufflation.
2Device complexity
If conventional imaging systems are used, then device complexity is minimized, but information completeness deteriorates because concealed structures and three-dimensional dimensions cannot be recognized
Solution Approach 1:
The system transitions from conventional two-dimensional imaging to three-dimensional visualization by capturing depth information and spatial relationships. The imaging system renders concealed structures in three dimensions, allowing surgeons to perceive anatomical depth, volume, and spatial configuration that are invisible in traditional flat images.
Solution Approach 2:
The imaging system enhances visualization by applying color coding to different anatomical structures, depths, or tissue types. This allows differentiated visualization of concealed structures through color differentiation, making it easier to identify and distinguish various anatomical features in the three-dimensional view.
3Measurement precision
If independent insufflation of two anatomical spaces is implemented, then measurement precision and surgical control are improved, but device complexity increases due to multiple scope devices and instruments
Solution Approach 1:
Each scope device is designed with multi-functionality, serving both as an imaging tool and an insufflation delivery system. The first scope device provides both extraluminal imaging and intraluminal insufflation, while the second scope device provides extraluminal imaging and intraluminal insufflation, reducing the need for separate dedicated instruments.
Solution Approach 2:
The system merges imaging and insufflation functions into integrated scope devices. The imaging system and insufflation system are combined in a unified platform that can simultaneously or sequentially perform both functions, reducing the total number of separate devices and instruments needed.
4Loss of information
If advanced imaging and distance sensing are added, then information completeness and surgical precision are improved, but device complexity and cost increase
Solution Approach 1:
The distance sensing and imaging systems are nested within the existing scope device structure. Sensors and imaging components are integrated into the distal end of the scope, allowing them to function as part of the unified instrument rather than as separate external systems, thereby reducing overall system complexity.
