Elastic Bracket Guide Wire Holder Slot Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide wire holders struggle to securely pick up and hold medical guide wires due to the one-sided opening of the deflection and tensioning bracket, which can lead to instability and slippage, especially when the guide wire expands due to its inherent elasticity.
Innovation Solution
A guide wire holder design featuring two bracket parts with a slot that is positioned and oriented outside the guide wire's expansion path, providing a secure grip by having a slot width that is either equal to or less than the guide wire's transverse dimension, and utilizing elastic bracket parts that can be pushed apart to accommodate the guide wire's expansion, with additional features like protruding support members and frictional materials to enhance holding capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a one-sided opening deflection and tensioning bracket is used, then the device complexity is reduced, but the guide wire holding stability deteriorates
Solution Approach 1:
The bracket is divided into two separate bracket parts (first bracket part and second bracket part) that can be pushed apart elastically. This segmentation allows the bracket to adapt to the guide wire's expansion while maintaining holding stability, resolving the contradiction between simple structure and stable holding.
Solution Approach 2:
The bracket parts are designed to be elastically deformable rather than rigid. They can be pushed apart when the guide wire expands due to elasticity, and then return to their original position to maintain continuous contact and holding force, ensuring stable guide wire retention throughout the procedure.
2Stability of the object's composition
If the slot width is reduced below the guide wire transverse dimension, then the guide wire holding stability improves, but the ease of operation deteriorates
Solution Approach 1:
The bracket parts are made elastically deformable so they can be pushed apart during guide wire insertion to accommodate the transverse dimension of the guide wire, and then return to their original position to provide secure holding with slot width below the transverse dimension, resolving the contradiction between ease of insertion and stable holding.
Solution Approach 2:
The effective slot width changes dynamically: during insertion it is larger (when bracket parts are pushed apart), and during holding it is smaller (when bracket parts return to original position). This parameter change resolves the contradiction between ease of operation and holding stability.
3Stability of the object's composition
If the slot is positioned outside the guide wire expansion path, then the guide wire holding stability improves, but the device complexity increases
Solution Approach 1:
The slot is specifically positioned and oriented outside the guide wire expansion path, creating a localized geometric feature that prevents the guide wire from slipping out while it expands. This targeted local design achieves stable holding without requiring complex overall bracket restructuring.

AI summary
The invention relates to a guide wire holder (1) for receiving and holding an inherently elastic medical guide wire (4) and for attaching same to a medical device, such as an endoscope, having an attachment part (2) through which the guide wire (4) can be guided and a guide wire support (3) which is connected to the attachment part (2), projects from same, and allows the guide wire (4) to be held by means of a guide wire receiving device (9, 5, 7). The guide wire receiving device contains a first guide wire deflecting element (9) in the form of a deflecting and clamping bracket (9) which is open on one side, said guide wire deflecting element guiding the guide wire (4) away from the attachment part (2) and clamping the guide wire, and the guide wire receiving device contains two additional guide wire deflecting elements (5, 7). The deflecting and clamping bracket (9) has two bracket parts (9a, 9b) which project from the guide wire support (3) and between which a slot (10) is provided. The slot runs between the two bracket parts (9a, 9b) in one position and/or alignment located outside of a guide wire expansion path of the guide wire support (3), said expansion path being determined by the inherent elasticity of the guide wire (4).
