Solution Overview
Problem
Current methods for endoluminal negative pressure therapy in the gastrointestinal tract face challenges in simplifying handling, shortening procedure duration, and enhancing safety, particularly when treating anastomotic insufficiencies and abscesses, due to complexities in inserting and positioning fluid collection bodies within branching cavities.
Innovation Solution
A device featuring a sponge body with a suction hose and a pre-attached barrel loop, designed for precise endoscopic placement, which includes a grasping loop for easy handling and secure attachment to endoscopic instruments, allowing for efficient and safe application of negative pressure therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fluid collection body is inserted into a branching cavity using conventional methods, then the wound cavity can be accessed for therapy, but the handling becomes complex and the procedure duration increases
Solution Approach 1:
The patent applies preliminary action by pre-attaching a grasping loop to the fluid collection body before insertion. This allows the device to be easily grasped and positioned by endoscopic instruments, simplifying the insertion process into branching cavities while ensuring accurate placement without requiring complex manipulation during the procedure.
Solution Approach 2:
The grasping loop serves as an intermediary element that facilitates the interaction between the endoscopic instrument and the fluid collection body. This mediator enables easy handling and precise positioning of the device within the complex branching cavity structure, reducing both insertion complexity and improving placement accuracy.
2Volume of moving object
If the fluid collection body is made small enough to fit in branching cavities, then accessibility is improved, but the ability to collect sufficient fluid is reduced
Solution Approach 1:
The patent applies segmentation by designing the fluid collection body with a conical shape that tapers to a smaller tip, allowing it to navigate branching cavities effectively. The segmented design enables the distal end to access narrow cavity openings while the larger proximal portion provides sufficient fluid collection capacity, thus resolving the contradiction between size and accessibility.
3Productivity
If the insertion procedure is simplified, then the procedure duration is reduced, but the precision of placement may be compromised
Solution Approach 1:
The pre-attached grasping loop enables simplified handling and faster insertion procedures. The loop is prepared in advance, allowing endoscopic instruments to quickly grasp and position the fluid collection body without requiring complex manipulation steps, thus improving procedure efficiency while maintaining placement precision through controlled positioning.
