Over-the-scope clip with repositionable transparent cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic closure devices, particularly over-the-scope clips, can be difficult to use, time-consuming to position, and insufficient for certain perforations, conditions, and anatomies, as they require deploying the clip without visualizing it until deployment.
Innovation Solution
A clipping system that includes a transparent cap mounted over an endoscope, allowing the clip to be moved between an insertion configuration, a review configuration where the clip is visible, and a deployed configuration, using a deployment element and a repositioning element to facilitate precise positioning and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the clip is deployed without visualizing it until deployment, then the deployment mechanism is simplified, but the positioning precision and reliability are reduced
Solution Approach 1:
The cap is made transparent or translucent, allowing the operator to visually observe the clip's position relative to the target tissue through the cap during the deployment process, thereby improving positioning precision without complicating the deployment mechanism
Solution Approach 2:
The transparent cap serves as an intermediary between the operator and the clip, providing visual feedback about the clip's position while maintaining the simplicity of the deployment mechanism. The cap allows light transmission so the operator can see through it to monitor the clipping process
2Productivity
If the clip is deployed without visual confirmation, then the procedure time is reduced, but the risk of misplacement increases
Solution Approach 1:
The transparent cap enables real-time visual confirmation of the clip's position during deployment, allowing operators to verify correct placement immediately while maintaining efficient procedure timing
Solution Approach 2:
The transparent cap provides visual feedback to the operator during the clipping process, enabling real-time monitoring and confirmation of clip position relative to target tissue, thereby improving placement accuracy without significantly extending procedure time
3Manufacturing precision
If the clip is moved between multiple configurations for visualization, then the positioning accuracy is improved, but the device complexity increases
Solution Approach 1:
The transparent cap allows the clip to be visualized in various positions during movement and deployment, improving positioning accuracy without requiring complex mechanical systems for positioning control
Solution Approach 2:
The clip is designed to be movable relative to the cap between insertion, review, and deployed configurations, allowing dynamic adjustment and visual confirmation of position while maintaining a relatively simple overall device structure

AI summary
A clipping system includes a cap configured to be mounted over a distal end of an endoscope. A clip mountable over the cap to move between an insertion configuration, in which first and second jaws extend over opposing portions of the cap so that the first and second jaws are separated from one another, a review configuration, in which the clip is moved distally relative to the cap so that a portion of the clip extends distally until at least a portion of the clip extends into a field of view of the optical system of an endoscope on which the cap is mounted, and a deployed configuration in which the clip is moved distally off of the clip so that the first and second jaws are drawn toward one another under the bias of the at least one hinge to close over tissue received therebetween.
