Repositionable Over-the-Scope Clip System With Visible Sequential Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic closure devices, particularly over-the-scope clips, are difficult to use, time-consuming, and insufficient for certain perforations and anatomies, requiring multiple insertions and deployments due to the operator's inability to see the clip during deployment and limited capacity for multiple clip placements.
Innovation Solution
A clipping system featuring a transparent holder with multiple clips stacked along its length, each independently deployable from a pusher element, allowing for visual confirmation and sequential deployment without removing the endoscope, facilitated by a control mechanism for precise clip placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current over-the-scope clips are used, then tissue closure can be achieved, but the operator cannot see the clip during deployment and must remove the endoscope to place additional clips
Solution Approach 1:
Multiple clips are nested within a single deployable device, allowing sequential deployment of multiple clips during one endoscope insertion. The clips are stored in a compact arrangement within the device body and can be deployed one at a time as needed, eliminating the need to remove and reload the endoscope for each clip placement.
Solution Approach 2:
Multiple clips are pre-loaded into the device before insertion, allowing the operator to have multiple clips ready for deployment during a single procedural session. This preliminary preparation enables continuous operation without repeated endoscope removal and reloading.
2Productivity
If current over-the-scope clips are used, then single clip deployment is possible, but multiple clip placements require endoscope removal and reloading
Solution Approach 1:
Multiple clips are nested within a single deployable device, allowing sequential deployment of multiple clips during one endoscope insertion. The clips are stored in a compact arrangement within the device body and can be deployed one at a time as needed, eliminating the need to remove and reload the endoscope for each clip placement.
Solution Approach 2:
The device serves multiple functions: it can deploy multiple clips sequentially, allows visualization of each clip before deployment, and maintains the capability to position and deploy clips at different locations along the GI tract, all within a single endoscope insertion procedure.
3Reliability
If current endoscopic closure devices are used, then tissue closure can be achieved, but the devices are difficult to use and time-consuming to position
Solution Approach 1:
The device incorporates a visualization system that provides real-time feedback to the operator about the position and orientation of each clip relative to the target tissue. This allows the operator to see exactly where each clip will be deployed, enabling precise positioning and adjusting the placement as needed before actual deployment occurs.
Solution Approach 2:
The device allows dynamic adjustment of clip position and deployment timing. The operator can advance the device to position clips, visualize the target area, adjust the position if needed, and deploy clips sequentially based on real-time visualization feedback, making the positioning process flexible and adaptive rather than fixed and rigid.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and precise multiple clip deployments directly visible to the operator, reducing procedural time and improving the ability to treat complex tissue defects with a single endoscope insertion.
Implementation Method 1
a pusher element mounted over the holder, proximally of the plurality of clips, the pusher element configured to be moved distally along the holder to independently deploy each of the plurality of clips from the holder
Implementation Method 2
each clip being independently deployable from the holder so that, upon release of the clip from the holder, the clip is permitted to revert to a biased closed configuration, in which the first and second ends are moved toward one another to reduce a size of the tissue-receiving space so that tissue is gripped therewithin
Data Source
AI summary
A clipping system includes a pusher element, a holder mounted over an insertion device and clips stacked along a length of the holder. The holder includes a longitudinally channel. Each clip extends along a curvature defining a tissue-receiving space therewithin and extends about the holder with an exterior surface of the holder holding the clip open with the first and second ends of the clip separated from one another to receive a tissue therein. Each clip is independently deployable from the holder so that, upon release of the clip from the holder, the clip reverts to a closed configuration. In the closed configuration, the first and second ends are moved toward one another to reduce a size of the tissue-receiving space so that tissue is gripped therewithin. The element is mounted over the holder and moved distally along the holder to independently deploy each clips.
