Endoscope Clip System with Sliding Mounting Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for deploying multiple surgical clips within the body are cumbersome, time-consuming, and expensive due to the need to repeatedly remove and reload the system to deploy each clip individually.
Innovation Solution
A system comprising a mounting bar on an endoscope with clips having recesses for slidably receiving the bar, allowing multiple clips to be advanced and deployed sequentially without removing the system from the body, with a control member to actuate the clips to grip tissue as they move beyond the endoscope's distal end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional systems deliver only one clip at a time and must be removed from the body to load a new clip, then the system structure remains simple, but the deployment process becomes complicated and time-consuming
Solution Approach 1:
Multiple clips are mounted simultaneously on a single mounting bar that is introduced through one endoscope, merging multiple clip delivery functions into one integrated system. This eliminates the need for repeated system removal and reloading, directly improving clip deployment efficiency while accepting increased system complexity
Solution Approach 2:
The mounting bar is designed as a separate modular component that can be mounted on or removed from the endoscope. This segmentation allows the clips to be delivered together as a group while maintaining the ability to separate the mounting bar from the endoscope for reloading, balancing productivity improvement with operational flexibility
2Loss of time
If multiple clips are deployed using conventional systems, then the desired number of clips can be placed, but the procedural time and cost increase significantly
Solution Approach 1:
Multiple clips are pre-mounted on the mounting bar before introduction into the body through the endoscope. This preliminary preparation of multiple clips in advance eliminates the need for repeated system removal and reloading during the procedure, directly reducing procedural time while the control member simplifies the operation of deploying each clip sequentially
3Productivity
If clips are advanced along the mounting bar and deployed sequentially, then continuous operation is achieved, but the mechanism for controlling clip deployment becomes more complex
Solution Approach 1:
A control member acts as an intermediary component that engages with the clips on the mounting bar to advance and deploy them sequentially. This single control mechanism coordinates the deployment of multiple clips in sequence, achieving continuous operation capability while concentrating the control complexity into one dedicated component rather than requiring separate control for each clip
Applied Scientific Principles

Function Achieved in This Case
Enables efficient and rapid deployment of multiple clips to body tissues, reducing procedural time and cost by allowing continuous operation without the need for frequent system removal and reloading.

AI summary
A device for compressing body tissue includes a clip having a connection portion with first and second clip arms extending therefrom, the clip includes a recess formed on an inner surface of the connection portion, the recess being shaped and sized to slidably receive a mounting bar coupled to an outer surface of an endoscope on which the mounting bar is mounted with inner surfaces of the first and second clip arms maintained in an open position by contact between an endoscope on which the mounting bar is mounted and the inner surfaces of the first and second clip arms. The clip is slidable over the outer surface of an endoscope on which the mounting bar is mounted until the clip moves distally beyond the distal end of the endoscope so that the first and second clip arms spring closed to grip tissue therebetween.
