Endoscope Coupling Adaptor for Colon Fluid Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic procedures, such as colonoscopy, face challenges in maintaining optimal maneuverability, stability, and unobstructed vision within the colon, particularly due to issues with fluid management and instrument insertion.
Innovation Solution
A lumen fluid conducting and endoscope coupling adaptor that includes a proximal external body-recliner, an interim protruding muzzle, a distal collapsible intra-lumen clutch, and a fluid-conducting arrangement with a suction port and irrigation nozzle, allowing for effective insertion, fixation, and fluid management within the colon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible endoscope is inserted through the entire length of the colon, then diagnostic and therapeutic examination is enabled, but maintaining optimal maneuverability and stability becomes difficult due to fluid accumulation and instrument interference
Solution Approach 1:
The adaptor is divided into multiple functional segments: a proximal external body-recliner for patient interface, an interim protruding muzzle for lumen penetration, and a distal collapsible intra-lumen clutch for fixation. This segmentation allows each component to perform its specific function optimally while maintaining overall system versatility for endoscopic procedures.
Solution Approach 2:
The adaptor serves as an intermediary device between the external endoscope and the internal lumen environment. It includes a collapsible clutch that acts as a mediator for fixation, and a fluid-conducting arrangement with suction ports that mediates fluid management, thereby improving maneuverability and stability during the procedure.
2Adaptability or versatility
If the endoscope is maneuvered through the colon, then direct examination is achieved, but unobstructed vision is compromised due to fluid accumulation in the lumen
Solution Approach 1:
The fluid-conducting arrangement includes suction ports that continuously remove accumulated fluids from the lumen, providing real-time feedback control to maintain optimal vision conditions. The system monitors and responds to fluid accumulation by activating suction to clear the field of view, ensuring unobstructed vision throughout the examination.
Solution Approach 2:
The suction ports extract and remove accumulated fluids from the lumen, separating the harmful fluid accumulation from the diagnostic field of view. This extraction mechanism directly addresses the vision obstruction problem by removing the interfering substance (fluids) that compromises illumination and visibility.
3Adaptability or versatility
If the endoscope is inserted into the lumen, then diagnostic examination is enabled, but instrument insertion and fluid management becomes complex
Solution Approach 1:
The adaptor merges multiple functions into a single integrated device: it combines the endoscope coupling mechanism, fluid-conducting arrangement with suction ports, irrigation nozzle, and fixation clutch. This consolidation simplifies the overall system by integrating what would otherwise be separate complex subsystems into one coordinated unit, making instrument insertion and fluid management more manageable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adaptor ensures unobstructed vision and improved maneuverability by maintaining a stable position within the colon, facilitating effective fluid drainage and irrigation, and aiding in the removal of debris, thereby enhancing the efficiency of endoscopic procedures.
Implementation Method 1
a distal collapsible intra-lumen clutch configured to assume a folded narrow state allowing insertion and retraction through the lumen entry and proximal portion of the lumen, and to assume an expanded state in the lumen, distally of the proximal portion, for fixating the adaptor
Implementation Method 2
The collapsible intra-lumen clutch may include an inflatable balloon fixed to the clutch, wherein inflating of the balloon expands the clutch into the expanded state
Implementation Method 3
a lumen seal for preventing backflow of the lumen fluids by sealing a gap between the protruding muzzle and the lumen when the protruding muzzle is inserted within the lumen
Implementation Method 4
a proximal seal for preventing outward leakage of the lumen fluids, disposed proximally of the adaptor, configured to seal the peripheral conduit and around the endoscope when inserted in the endoscope bore
Implementation Method 5
a fluid suction port in fluid communication with the peripheral conduit for releasing lumen fluids entering the peripheral conduit from the lumen
Implementation Method 6
an irrigation nozzle, configured to spurt cleansing fluid through said adaptor
