Reloadable Clip Cartridge Structure for Endoscopic Applicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cartridge systems for endoscopic clip units cannot reload a clip unit after it has been loaded, requiring the entire cartridge to be discarded, which is inefficient and wasteful.
Innovation Solution
A cartridge system with a storage area that includes a first area to retract the clip unit's wings and prevent connection, and a second area to connect the connection arm with the applicator, allowing for the clip unit to be restored and repeatedly reloaded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a clip unit is loaded into an applicator from a cartridge, then the clip unit can be deployed for treatment, but the cartridge cannot be reloaded and must be discarded
Solution Approach 1:
The cartridge is divided into two functional areas: a first area for storing and retracting the clip unit, and a second area for connecting the connection arm with the applicator. This segmentation allows the clip unit to be independently manipulated and reloaded without discarding the entire cartridge structure.
Solution Approach 2:
The invention enables recovery and reuse of the cartridge body after clip unit deployment. The cartridge can be emptied, reloaded with a new clip unit, and reused multiple times, transforming the traditionally disposable cartridge into a reusable component.
2Ease of operation
If the storage area allows connection arm connection, then the clip unit can be deployed, but the clip unit cannot be retracted for reloading
Solution Approach 1:
The storage area transitions between two dynamic states: a first state where the connection arm is prevented from connecting (allowing clip unit retraction and reloading), and a second state where connection is enabled (allowing applicator attachment). This dynamic switching enables both reliable deployment and efficient reloading.
Solution Approach 2:
The system prepares the clip unit in advance by retracting it into the first area where connection is prevented, allowing the clip unit to be positioned and prepared for subsequent reloading without accidental connection or deployment.
3Productivity
If the cartridge is designed for single-use, then manufacturing and operation are simple, but waste is generated and operational efficiency decreases
Solution Approach 1:
The cartridge is designed to perform multiple functions: storing the clip unit, preventing premature connection, enabling controlled deployment, and allowing repeated reloading. This multi-functionality increases operational efficiency while the modular first and second areas keep the structural complexity manageable.
