Biopsy Cap Contoured Bore for Endoscope Port Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope assemblies and biopsy caps have limitations and variations that necessitate the development of alternative designs and materials for improved compatibility and functionality.
Innovation Solution
A biopsy cap with a rotationally symmetrical bore featuring a contoured inner surface, including specific diameters and configurations for lips and grooves to accommodate different endoscope biopsy ports, is designed for enhanced compatibility and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a biopsy cap is designed to fit multiple different endoscope biopsy ports with varying dimensions, then compatibility and versatility are improved, but the device complexity increases due to the need for multiple sealing surfaces and precise dimensional specifications
Solution Approach 1:
The biopsy cap is designed with a multi-level contoured bore that can accommodate multiple different biopsy port configurations. The bore includes first and second lips with different diameters, and first and second grooves at different vertical levels, allowing the same cap to seal effectively against both first and second types of biopsy ports with varying flange and body dimensions
Solution Approach 2:
Different regions of the bore interior are given different diameters and depths to match specific features of different biopsy ports. The first lip and first groove correspond to the first biopsy port dimensions, while the second lip and second groove correspond to the second biopsy port dimensions, creating localized sealing zones for each port type
2Reliability
If the biopsy cap uses a contoured bore with multiple lips and grooves to ensure secure sealing, then sealing effectiveness is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The biopsy cap is pre-configured with specifically dimensioned lips and grooves during manufacturing to match the dimensions of different biopsy port flanges and bodies. The first lip diameter corresponds to the first biopsy port body diameter, the first groove diameter corresponds to the first biopsy port upper flange diameter, and similarly for the second lip and groove, ensuring proper sealing engagement before use

AI summary
Devices, systems, and methods for a cap adapted to biopsy ports for an endoscope. Multiple internal features of the rotationally symmetrical bore allow for a tight, operative fit when the cap is placed on any of multiple different biopsy ports, even though the ports have significant differences in both height and shape. Alternating lips and grooves within the contour of the internal bore correspond to different bodies and flanges of the biopsy ports.
