Endoscope Clipping Device With Breakable Magnetic Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscope clipping devices can irritate affected areas during the separation of magnetic bodies connected to gripped body tissue, necessitating improvements to minimize tissue irritation and facilitate easier separation.
Innovation Solution
A clipping device for an endoscope featuring a connecting portion that breaks under tension, a magnetic body portion with different polarities, a cap portion guiding the connecting portion, and a biodegradable connector made of gelatin to facilitate easy separation and minimize tissue irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic body is used to hold the clipping device, then the clipping device can be securely attached to grip body tissue, but separating the magnetic body from the gripped tissue causes irritation to the affected area
Solution Approach 1:
The device is divided into separate components: a reusable cap portion with clipping mechanism and a disposable body portion containing the magnetic body. This segmentation allows the magnetic body to be easily removed and discarded, preventing tissue irritation during separation while maintaining secure attachment during use.
Solution Approach 2:
The body portion containing the magnetic body is designed as a disposable component that is discarded after single use. This eliminates the need to separate the magnetic body from gripped tissue, as the entire body portion is removed as a unit, thereby preventing tissue irritation that would occur with conventional reusable magnetic bodies.
2Productivity
If a reusable magnetic clipping device is used, then the device can be used multiple times, but the magnetic body cannot be easily separated from the gripped tissue without causing irritation
Solution Approach 1:
The device is segmented into a reusable cap portion and a disposable body portion. The cap portion containing the clipping mechanism can be reused, while the body portion with the magnetic body is discarded after single use, eliminating separation difficulties and tissue irritation.
Solution Approach 2:
The body portion is designed as a low-cost disposable component that is discarded after one use. This approach maintains productivity by allowing repeated use of the expensive cap portion while eliminating the operational complexity of separating magnetic bodies from tissue.
3Device complexity
If a permanent connection between the magnetic body and cap portion is used, then the device structure is simple, but the magnetic body cannot be easily removed from the body
Solution Approach 1:
The body portion containing the magnetic body is designed as a disposable component that is discarded after single use. This eliminates the need for complex removal mechanisms while maintaining simple device structure, as the entire body portion is removed as a complete unit rather than requiring separation of individual components.
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
The device allows for efficient suturing and easy removal of the clipping device from the body by breaking under tension and using a biodegradable connector, reducing tissue irritation and aiding in quick recovery.
Implementation Method 1
a body portion which includes a first inside path portion through which the connecting portion moves and which has a magnetic force
Implementation Method 2
a connector which connects the body portion to the cap portion and includes a material biodegradable in a human body

AI summary
The clipping device includes a connecting portion which is moved while being connected to a wire of the endoscope and has a body broken when tension more than a set value is applied thereto, a body portion which includes a first inside path portion through which the connecting portion moves and has a magnetic force, a cap portion which is located on a side of the body portion, includes a second inside path portion connected to the first inside path portion, and guides movement of the connecting portion, a clipping portion which is connected to the connecting portion protruding through the cap portion and contracts due to movement of the connecting portion to grip body tissue, and a connector which connects the body portion to the cap portion and includes a material biodegradable in a human body.
