Endoscopic Pressing Member for Tissue Confinement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic treatment systems face challenges in preventing other organs from being inadvertently drawn into the endoscope during procedures, complicating the procedure and making it difficult to capture images of lesions, which hinders the operability of the treatment tool and maintains an open environment for biological tissue coalescence.
Innovation Solution
A pressing member with an entanglement preventing portion is used to press neighboring tissues and restrict the width of the treatment target portion, preventing other organs from being drawn into the endoscope by maintaining the thickness of the drawn-in tissue to a predetermined value, either through a pressing portion or an elastic member, and facilitating the identification and grasping of the treatment target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ligating tool or suture thread is passed through the alimentary tract to overlap with the tract, then the tract can be deformed like a pouch to prevent lumen coalescence, but other organs positioned adjacent to the treatment target may be inadvertently sutured, complicating the procedure
Solution Approach 1:
A pressing member is introduced as an intermediary device between the endoscope and the alimentary tract. This pressing member includes a pressing portion that applies pressure to the tract wall and an entanglement preventing portion that physically blocks other organs from being drawn into the endoscope. The pressing member enables reliable lumen coalescence prevention while simplifying the procedure by preventing inadvertent suturing of adjacent organs.
Solution Approach 2:
The pressing member is divided into distinct functional segments: a pressing member main body that presses the alimentary tract, and an entanglement preventing portion that prevents other organs from being drawn in. This segmentation allows each part to perform its specific function independently, ensuring reliable treatment while preventing procedural complications.
2Ease of operation
If the opening is formed on the lateral surface of the overtube, then the lesion can be accessed for treatment, but it becomes difficult to capture the image of the lesion using the image capturing portion, deteriorating operability
Solution Approach 1:
Instead of forming the opening on the lateral surface of the overtube, the invention inverts the approach by forming the opening at the distal end of the pressing member. This inversion allows the image capturing portion to directly view the lesion through the opening, improving image capture capability while maintaining lesion accessibility for treatment.
3Reliability
If the ligating tool or suture thread is passed through the alimentary tract, then the tract can be deformed to overlap front and back sides, but it is difficult to maintain a closed environment until the biological tissue is coalesced
Solution Approach 1:
The pressing member serves as an intermediary device that creates a controlled environment for tissue coalescence. By pressing the alimentary tract and preventing other organs from being drawn in, it maintains a closed environment that facilitates reliable tissue coalescence without requiring complex additional devices.
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
This solution simplifies the procedure by ensuring only the intended biological tissue is drawn into the endoscope, improving operability and maintaining a closed environment for secure suturing, thus preventing entanglement of other organs and enhancing the efficiency of the endoscopic treatment.
Implementation Method 1
a pressing member main body disposed between a treatment target portion of a biological tissue and an endoscope inserted into the body of a patient for treatment of the treatment target portion of the biological tissue, the pressing member main body being configured to press neighboring tissues around the treatment target portion by abutting the treatment target portion
Implementation Method 2
the entanglement preventing portion has an elastic member, and the elastic member is configured to maintain the thickness of the drawn-in treatment target portion to a predetermined thickness

AI summary
An endoscopic treatment system 1 of the present invention includes an overtube 2 that is inserted into the body of a patient. An endoscope 7 and a suturing device 8 are inserted into the overtube 2. The overtube 2 has a long and flexible tube main body 3, and a chamber 4 is provided at the distal end of the tube main body 3. The chamber 4 has a lateral hole 10 formed on the lateral surface thereof. The width of the lateral hole 10 is set such that a lesion can be drawn into the lateral hole 10 while preventing other organs on the periphery of the lesion from being drawn into the lateral hole 10.
