Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional surgical visualization systems are used, then visualization capability is provided, but the systems are heavy and cumbersome
Solution Approach 1:
The visualization system is divided into separate components: a reusable console unit and disposable endoscopic assemblies. This segmentation allows the heavy, complex electronics to be isolated in a stationary console while the distal visualization elements remain lightweight and easily replaceable, resolving the contradiction between system weight and visualization stability.
Solution Approach 2:
The endoscopic visualization system is nested within a surgical access device, with the camera module integrated into the distal end of the access device. This nesting eliminates the need for separate handheld visualization equipment, reducing overall system complexity and weight while maintaining stable visualization through integrated positioning.
2Ease of manufacture
If traditional surgical visualization systems are used, then visualization is provided, but they are difficult to clean or sterilize
Solution Approach 1:
The endoscopic visualization assembly is designed as a disposable component that can be discarded after a single use, eliminating the need for complex cleaning and sterilization processes. This disposable approach ensures sterility while simplifying the overall system design, as the disposable unit contains all necessary visualization components in a sealed, pre-sterilized package.
3Ease of operation
If spinal endoscope is used, then limited procedures can be performed, but multiple human operators are required
Solution Approach 1:
The visualization system is merged with the surgical access device into a single integrated assembly. This combination allows the surgeon to perform multiple functions (access and visualization) with one device, eliminating the need for separate operators to hold the endoscope while maintaining versatility through the integrated design that accommodates various surgical instruments through the same access channel.
4Ease of operation
If visualization orientation is dictated by instrument orientation, then visualization is provided, but the learning curve is steep
Solution Approach 1:
The system replaces mechanical orientation coupling with electronic image processing and display. The camera captures images that are then processed and displayed in a consistent, surgeon-friendly orientation regardless of the physical orientation of the endoscope. This decoupling of mechanical orientation from visual presentation reduces the learning curve while preserving complete spatial information through image processing algorithms.
