Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guidewire connectors for ultrasonic wave generation in minimally invasive medical procedures face challenges in maintaining cleanliness and avoiding interference with other instruments during insertion, particularly due to the need for a smaller outer diameter and ensuring sterility.
Innovation Solution
A guidewire connector with a detachable adapter member and a wire fixing mechanism that matches or is smaller than the guidewire's outer diameter, allowing for secure attachment without obstructing other instruments and ensuring cleanliness through disposable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a guidewire connector is used for ultrasonic wave generation, then ultrasonic imaging capability is improved, but the outer diameter increases interfering with instrument introduction
Solution Approach 1:
The optical fiber is embedded within the guidewire structure, with the connector configured to receive and secure the optical fiber inside the guidewire's outer diameter constraints. This nesting approach allows ultrasonic imaging functionality to be integrated without increasing the overall outer diameter that would interfere with instrument introduction.
Solution Approach 2:
The connector utilizes a detachable adapter configuration that connects laterally rather than extending axially, allowing the optical fiber to be coupled to the guidewire in a manner that does not increase the guidewire's outer diameter in the axial direction, thus avoiding interference with instrument introduction.
2Object-affected harmful factors
If a detachable adapter member is used, then cleanliness is maintained, but device complexity increases
Solution Approach 1:
The connector is divided into a detachable adapter member and a guidewire component, allowing the adapter to be disposed of after a single use while maintaining the guidewire for potential reuse. This segmentation enables cleanliness to be maintained through disposable components without requiring the entire device to be complex.
Solution Approach 2:
The detachable adapter member serves as an intermediary component that interfaces between the optical fiber and the guidewire, allowing for easy connection and disconnection while maintaining sterility barriers. This intermediary approach simplifies the overall system by providing a standardized interface that can be easily manufactured and disposed of.
