Resilient Securement Structure for Endoscope Cap Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ligation banding cap assemblies for endoscopes are not suitable for a wide range of endoscope sizes, leading to issues such as misalignment, instability, inadequate sealing, and poor connection, which can result in incorrect or incomplete deployment of ligation bands and increased manufacturing and inventory costs due to the need for multiple sizes.
Innovation Solution
A securement structure with resilient projections is positioned inside the channel of a cap assembly, compressing between the endoscope and the cap to secure the cap to the endoscope, allowing for a snug fit across various endoscope sizes, reducing the need for multiple cap sizes and improving connection stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ligation banding cap assembly is designed for a particular endoscope size, then the connection is stable and secure, but the device cannot accommodate a wide range of endoscope sizes
Solution Approach 1:
The adapter incorporates a resilient securement structure that can change its physical state (compressed vs. relaxed) to adapt to different endoscope diameters. By varying the compression parameter of the resilient material, the adapter maintains reliable connection across multiple endoscope sizes without requiring multiple specialized components.
Solution Approach 2:
The adapter is designed as a universal component that can securely attach to endoscopes of various sizes within a specified range. The resilient securement structure enables a single adapter design to perform the function of multiple size-specific adapters, improving versatility while maintaining connection stability through the compression mechanism.
2Adaptability or versatility
If the resilient securement structure is compressed between the endoscope and cap, then a snug fit is achieved across various endoscope sizes, but the material must withstand compressive forces
Solution Approach 1:
The resilient securement structure utilizes changes in compression parameter to achieve adaptation. When compressed between the endoscope and cap, the material's density and rigidity increase, enabling it to withstand the compressive forces while maintaining the snug fit necessary for universal compatibility.
Solution Approach 2:
The adapter is constructed from resilient material that combines flexibility for compression with sufficient strength to withstand forces. This composite approach allows the material to be compressed for adaptation while maintaining the structural integrity needed to prevent failure under load.
3Reliability
If multiple cap sizes are manufactured to fit different endoscope sizes, then each connection is optimized, but manufacturing and inventory costs increase
Solution Approach 1:
The adapter serves as a universal interface that can optimally connect to multiple endoscope sizes without requiring multiple specialized cap designs. This single-component solution maintains reliable connections across size variations while eliminating the complexity of manufacturing and managing multiple cap size variants.
Solution Approach 2:
Rather than creating multiple fixed-size caps, the invention uses a single cap design with a resilient securement structure that changes its effective dimensions through compression. This parameter change allows one cap size to perform the function of multiple sizes, reducing device complexity while maintaining optimized connections.

AI summary
A securement structure is positioned inside a channel of a first medical device to facilitate securement of the first medical device to a second medical device. The first medical device may be a ligation banding cap, and the second medical device may be an endoscope. The securement structure is adapted to be compressed between the second medical device and the first medical device to secure them together. This allows parts of different sizes to fit together.
