Endoscopic Clip Positive Lock for Visible Tissue Closure
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 due to the inability to visualize the clip's position relative to the target tissue during deployment.
Innovation Solution
A clipping system with a cap-mounted clip that allows for visual confirmation and adjustment of the clip's position relative to the target tissue before deployment, featuring a movable clip within a cap that can be locked in the closed configuration using a snap-fit mechanism and controlled by a control member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If over-the-scope clips are used for tissue closure, then closure of larger tissue defects can be achieved, but the clip cannot be visualized during positioning and deployment
Solution Approach 1:
The patent introduces a cap as an intermediary component that houses the clip and provides a visualization window. This cap serves as a mediator between the clip and the operator's view, allowing the clip to be seen through the cap's window during positioning and deployment, thus resolving the visualization problem while maintaining the over-the-scope clip's tissue closure capability
Solution Approach 2:
The patent changes the deployment dimension by moving the clip from a fully enclosed state to a partially visible state through the cap's window. This dimensional change in visibility allows the operator to observe the clip's position relative to the tissue defect while maintaining the mechanical function of the over-the-scope clip
2Reliability
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 patent applies preliminary action by allowing the operator to position and visualize the clip within the cap before actual deployment. The clip can be pre-positioned and verified through the cap's window, ensuring correct placement before release, which simplifies the operation and reduces positioning time while maintaining reliable tissue closure
Solution Approach 2:
The cap's visualization window provides real-time feedback to the operator during clip positioning and deployment. The operator can observe the clip's movement and position relative to the tissue defect through the window, enabling continuous adjustment and verification, which improves ease of operation while ensuring reliable closure
3Reliability
If current endoscopic closure devices are used, then tissue closure can be achieved, but they are insufficient for certain perforations, conditions and anatomies
Solution Approach 1:
The patent enhances universality by combining the over-the-scope clip mechanism with a visualizable cap system. This hybrid design maintains the ability to close large tissue defects while adding visualization capability, making the device adaptable to various perforation sizes, conditions, and anatomical locations that require both substantial closure capability and precise positioning

AI summary
A clipping system includes a cap, a clip and a control member. The cap includes a channel extending therethrough. A proximal portion of the cap is mounted over the endoscope such that a distal portion of the cap extends distally past a distal end of an endoscope. The distal portion of the channel includes opposing surfaces therealong defining a tapered portion tapering from the distal end of the cap toward a proximal end. The clip is mounted within the cap. The clip includes jaws movably connected via hinges. At least one of the hinges is biased to move the jaws away from one another. The clip is movable relative to the cap between open and closed configurations. The control member longitudinally movable relative to the cap to move the clip between the open and closed configurations.
