Endovenous Wire Positioning and Guiding Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endovenous treatment methods are cumbersome and prone to errors due to the need for manual handling and positioning of flexible wire elements, such as optical fibers, within drive systems, which limits displacement stroke and increases the risk of accidental damage during treatment.
Innovation Solution
An endovenous treatment assembly that includes a positioning and guiding part integral with the flexible wire element, allowing for translation and engagement with drive rollers, enabling reliable and efficient manipulation and positioning of the wire element within the drive system, with features like a flexible guide sheath and storage support for easy handling and reduced friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling and positioning of flexible wire elements is used, then the practitioner can directly control the wire element, but the operations are restrictive and tedious and can cause accidental deterioration of the wire element
Solution Approach 1:
A positioning and guiding part is introduced as an intermediary component between the practitioner's manual operations and the flexible wire element. This positioning and guiding part includes guiding means that constrain and direct the wire element's movement, allowing the practitioner to handle the wire element through the guiding structure rather than directly manipulating the wire itself, thereby reducing the risk of accidental deterioration while maintaining controllability
2Ease of operation
If the flexible wire element has significant length to locate systems outside sterile field, then the treatment systems can be positioned outside sterile operating field, but it poses a problem of space requirement during removal operations
Solution Approach 1:
The flexible wire element is designed to be nested within or alongside the positioning and guiding part during storage and removal operations. The wire element can be coiled or folded within the positioning and guiding part's structure, allowing the long wire element to occupy minimal space when not in active use, while still maintaining sufficient length to extend treatment systems outside the sterile field during procedures
3Length of moving object
If drive rollers are used to drive the flexible wire element by friction, then the wire element can be driven over a very large stroke, but the wire element requires precise positioning between drive rollers which is tedious and error-prone
Solution Approach 1:
The positioning and guiding part incorporates self-aligning features that automatically position the flexible wire element correctly between the drive rollers without requiring manual adjustment by the practitioner. The guiding means within the positioning and guiding part ensure that the wire element presents itself in the correct orientation and location for engagement with the drive rollers, making the system self-servicing in terms of positioning and eliminating the tedious and error-prone manual positioning step

AI summary
An endovenous treatment assembly includes a wire element for delivering treatment doses, which is flexible and capable of being inserted, over a portion of its length, longitudinally into a vein, and a positioning and guiding part that manipulates the wire element. The positioning and guiding part includes at least a first means for guiding in translation a first portion of the wire element, the wire element being able to slide in the direction of its length relative to the first guiding means. The positioning and guiding part further includes a first mechanical assembly for removable mounting relative to a drive system, so that the first portion of the wire element can be positioned and guided by the positioning and guiding part so as to be able to be engaged with of the drive system for driving the wire element in the direction of its length at least in a first direction.
