Endoscopic Device Insertion via Guide Wire Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic device insertion methods into hollow organs using guide wires require collaborative operations between operators and assistants, are inefficient, and necessitate frequent insertion and removal through the guide wire, complicating procedures like bile and pancreatic duct interventions.
Innovation Solution
A method involving a flexible endoscope with a channel that engages an endoscopic device with a guide wire inside the body, allowing the device to be inserted into the hollow organ without needing to pass through the guide wire, eliminating the need for collaborative operations and simplifying the insertion process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the endoscopic device is inserted through the guide wire using collaborative operation, then the guide wire can be indwelt in the hollow organ, but the insertion process becomes complex and time-consuming
Solution Approach 1:
The patent extracts the endoscopic device from the guide wire insertion pathway. Instead of passing the device through the guide wire lumen, the device is inserted separately through the body opening while the guide wire remains indwelt in the hollow organ, eliminating the complex collaborative manipulation required for traditional guide wire-based device insertion
Solution Approach 2:
The patent segments the insertion process into independent steps: first indwelling the guide wire in the hollow organ, then separately inserting the endoscopic device through the body opening. This segmentation eliminates the need for coordinated manipulation between multiple operators and simplifies the overall procedure
2Adaptability or versatility
If the endoscopic device is frequently inserted and removed through the guide wire for device exchange, then multiple devices can be used, but the procedural time and operational complexity increase
Solution Approach 1:
The guide wire is indwelt in the hollow organ in advance, establishing a stable reference pathway before any endoscopic devices are inserted. This preliminary action allows for rapid device exchanges without requiring re-establishment of the guide wire position, reducing procedural time
Solution Approach 2:
The endoscopic devices are extracted from the guide wire insertion pathway and inserted independently through the body opening. This allows devices to be exchanged without removing or manipulating the guide wire, significantly reducing the time required for device exchanges while maintaining versatility
3Reliability
If collaborative operation is used for endoscopic device insertion, then the guide wire can be properly positioned, but the operational efficiency decreases
Solution Approach 1:
The guide wire is indwelt in the hollow organ through self-service manipulation by a single operator, without requiring collaborative assistance. The subsequent device insertion also proceeds independently, eliminating the need for coordinated operations between multiple operators and thereby improving work efficiency while maintaining positioning accuracy

AI summary
In a disclosed method for inserting an endoscopic device, in a state in which a guide wire is inserted through an opening of a hollow organ of a subject, the guide wire is indwelt in the hollow organ. Next, a flexible endoscope is made to approach the opening of the hollow organ. Next, inside of the body of the subject, an endoscopic device that projects from the tip of a channel of the endoscope slidably engages with the guide wire. Next, the endoscopic device is inserted into the hollow organ through the opening, along the guide wire. The guide wire that is indwelt once is subsequently used as a guide for second and subsequent insertions of endoscopic devices.
