Telescoping Endoscope Extension Device for Adjustable Working Channel Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices with predetermined shaft lengths often fail to be compatible with various auxiliary medical devices, such as endoscopes, leading to operational limitations and increased development and inventory costs due to the need for multiple device versions.
Innovation Solution
A telescoping extension device with a locking assembly that adjusts to multiple predetermined positions, allowing a medical device to extend a working channel of an endoscope by a fixed distance, ensuring compatibility with different auxiliary devices and ergonomic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a medical device has a predetermined shaft length, then it can be compatible with a specific auxiliary medical device, but it cannot work well with other auxiliary medical devices or patient treatment sites
Solution Approach 1:
The extension device incorporates a telescoping mechanism with an inner member and outer member that can slide relative to each other, allowing the shaft length to be dynamically adjusted. This enables a single device to accommodate multiple auxiliary devices and treatment sites by changing its length configuration, thereby resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The extension device is divided into separable components including an inner member, outer member, and locking assembly. These segmented parts can be adjusted and locked at different positions, allowing the device to be configured for different auxiliary devices without requiring multiple complete device versions.
2Length of moving object
If the shaft extends too far distally out of the working channel, then it reaches certain treatment sites, but it cannot be imaged with ultrasound and cannot operate as intended
Solution Approach 1:
The telescoping mechanism allows dynamic adjustment of the shaft extension length to match the specific working channel length of the auxiliary device being used. This ensures the distal tip remains within the ultrasound imaging range while still reaching the required treatment site, maintaining operational reliability.
Solution Approach 2:
The locking assembly provides visual indicators and mechanical feedback to ensure the inner and outer members are locked at the correct predetermined positions, confirming that the extension length is appropriate for the attached auxiliary device and will function reliably.
3Length of moving object
If the shaft extends too far distally, then it can reach treatment sites, but it extends beyond the functioning range of the echoendoscope
Solution Approach 1:
The adjustable telescoping mechanism allows the operator to configure the shaft length to match the specific ergonomic requirements and working range of different echoendoscopes, optimizing ease of operation for each procedural context.
