Endoscope Treatment Tool Guide Wire Holder Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope treatment systems face challenges in guiding treatment tools to target regions without the guide wire interfering with the operator's hand or becoming obstructive, as the guide wire is often inserted manually and can be cumbersome.
Innovation Solution
An endoscope treatment system with a flexible guide wire integrated into a multi-lumen tube and a holding fixture that secures the tube member to prevent interference, allowing the guide wire to be pre-inserted and easily maneuvered, with a fixing member that couples the operating section to the guide wire holder, keeping the distal and proximal ends outside the guide wire holder's circumference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide wire is manually inserted into the treatment tool, then the guide wire can be positioned in the treatment target region, but the guide wire becomes cumbersome and interferes with the operator's hand operation
Solution Approach 1:
The guide wire is pre-inserted into the treatment tool during manufacturing or assembly, so that when the operator uses the device, the guide wire is already in position and does not require manual insertion during the procedure, eliminating the cumbersome operation
Solution Approach 2:
The guide wire holder is designed to accommodate the guide wire within its structure, with the guide wire stored in a compact manner inside the holder, allowing the guide wire to be integrated into the treatment tool without increasing external dimensions
2Volume of moving object
If the guide wire is stored in a compact manner within the guide wire holder, then the system allows for compact storage, but the tube member may become obstructive or easily touched by the operator's hand
Solution Approach 1:
The distal and proximal ends of the operating section are positioned outside the circumferential boundary of the guide wire holder, utilizing spatial arrangement in multiple dimensions to prevent the tube member from being obstructive while maintaining compact storage
3Loss of time
If the guide wire is pre-inserted in the treatment instrument, then the step of inserting the guide wire is saved, but the guide wire may interfere with the operation of the syringe when stored in the tubular body
Solution Approach 1:
The guide wire holder is separated from the syringe operating section, with the guide wire stored in the dedicated holder rather than inside the syringe tubular body, allowing independent operation of the syringe without interference from the guide wire

AI summary
The endoscope treatment system includes an endoscope treatment tool that has an operating section including a distal end and a proximal end, and a sheath that is connected to the distal end of the operating section and is formed with a lumen into which the guide wire is capable of being inserted; a guide wire holder that has a tube member, in which the guide wire is accommodated, and that is circumferentially wound; and a fixing member that couples the operating section to the guide wire holder so that the distal end and the proximal end of the operating section are located outside the circumference of the guide wire holder.
