Endoscope Tip Fluid Distribution for Multi-Directional Cavity Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopes, such as colonoscopes, have limited field of view and limited options for operating medical and surgical tools, necessitating a broader view and extended access for surgical tools while maintaining functionality and efficient packing of elements in the tip section.
Innovation Solution
The endoscope tip features a base with multiple channels, a manifold, and an optical assembly with at least two cameras, along with a fluid distribution device that includes channels to distribute fluid to multiple openings, enhancing the field of view and enabling efficient distribution of surgical tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single camera is used in the endoscope tip, then the device complexity is reduced, but the field of view is limited
Solution Approach 1:
The endoscope tip is divided into multiple functional segments including a base, manifold, optical assembly, and fluid distribution device. Multiple cameras are positioned at different locations (front, side, rear) to capture different fields of view simultaneously, resolving the contradiction between limited view and device complexity through structured segmentation
Solution Approach 2:
The patent transitions from a single viewpoint to multiple viewpoints by positioning cameras in three-dimensional space around the tip (front, side, rear positions). This multi-dimensional camera arrangement expands the overall field of view while maintaining manageable device complexity through spatial distribution
2Adaptability or versatility
If multiple surgical tools are provided in the endoscope, then the versatility is improved, but the packing efficiency deteriorates
Solution Approach 1:
Multiple surgical tools are nested within the endoscope shaft, with tools arranged concentrically and positioned to allow passage through the flexible shaft. The fluid distribution device and manifold structure provide integrated pathways that accommodate multiple tools without significantly increasing the external diameter, resolving the contradiction between versatility and packing efficiency
Solution Approach 2:
Surgical tools are distributed in three-dimensional space within the tip section rather than arranged linearly. The manifold and fluid distribution device create multiple channels and pathways that allow tools to be positioned at different depths and angles, maximizing the use of available volume while maintaining versatility
3Adaptability or versatility
If fluid distribution is provided to multiple locations, then the functionality is improved, but the device complexity increases
Solution Approach 1:
The manifold and fluid distribution device are designed as multi-functional components that simultaneously distribute fluid to multiple locations (front camera, side cameras, rear camera) and provide structural support for the optical assembly. This universal design provides enhanced functionality while minimizing the increase in device complexity through component integration
Solution Approach 2:
The manifold and fluid distribution device are merged with the structural framework of the endoscope tip, combining fluid distribution pathways with the mechanical support structure. This integration allows fluid to be distributed to multiple camera locations without adding separate complex distribution systems, resolving the contradiction between functionality and device complexity

AI summary
There is provided herein a tip section for an endoscope assembly that includes a fluid distribution device for circulating fluid for cleaning a body cavity. In an embodiment, the tip section includes a groove aligned with side jet channels, where multiple holes drilled above the groove, through the periphery of a tip cover covering the tip section, provide an exit for the fluid circulated by the side jet channels in all directions around the tip cover. In another embodiment, the tip section includes a removable attachment that covers jet channel openings. Multiple holes drilled through the cover provide a multiple jet exit for the fluid circulated by the jet channels in multiple directions around the tip cover.
