Endoscope Tip Fluid Distribution for Wider Viewing and Tool Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopes have limited field of view and limited options for operating medical and surgical tools, with a need for broader access and efficient packing of elements in the tip section while maintaining functionality.
Innovation Solution
A fluid channeling component for an endoscopy tip with a front working channel, front jet channel, and at least one side jet opening, allowing for fluid distribution through predefined algorithms including continuous and pulsing fluid streams, and multiple viewing elements with isolated light guides and illuminators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple viewing elements and functional components are added to the endoscope tip section, then the field of view and operational capability are improved, but the device complexity and difficulty of packing elements efficiently increase
Solution Approach 1:
The endoscope tip is divided into multiple functional sections with separate viewing elements (front-pointing camera, side-pointing cameras) and distinct fluid channels (front jet channel, side jet channels, irrigation channel). Each segment performs a specific function, allowing complex capabilities to be achieved through modular organization rather than a monolithic structure.
Solution Approach 2:
Multiple functional elements are nested within the tip section housing, with cameras, illuminators, and fluid channels arranged in a compact nested configuration. The side jet channels are positioned adjacent to viewing elements, and fluid channels are routed through the internal structure, enabling efficient space utilization.
2Adaptability or versatility
If more functional elements are packed into the tip section, then the versatility is improved, but the manufacturing precision and assembly difficulty worsen
Solution Approach 1:
The tip section is designed as a multi-functional integrated unit where a single component structure serves multiple purposes. The housing accommodates viewing elements, illuminators, and fluid channels simultaneously, and the fluid distribution system provides both irrigation and jet functions through a unified channeling component.
Solution Approach 2:
Multiple functional components are merged into a single integrated tip section assembly. The viewing elements, illuminators, and fluid channels are combined in a unified structure rather than separate assemblies, reducing the number of discrete parts and simplifying manufacturing while maintaining versatile functionality.
3Adaptability or versatility
If fluid distribution channels are added for cleaning body cavities, then the functional capability is improved, but the device complexity increases
Solution Approach 1:
The fluid distribution system is segmented into distinct channels: a front jet channel for anterior cleaning, side jet channels for lateral cleaning, and an irrigation channel for fluid delivery. Each channel is independently routed and controlled, allowing precise fluid delivery to different locations without requiring a complex single-channel system.
Solution Approach 2:
A fluid distribution component acts as an intermediary between the fluid source and the various jet/irrigation outlets. This intermediate component channels fluid through multiple pathways, simplifying the overall system architecture by centralizing fluid management rather than requiring separate fluid delivery mechanisms for each function.

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.
