Imaging Catheter Metal Wire Grounding for Static-Resistant Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue with existing imaging devices is that the photographing assembly, being an electronic component, is highly susceptible to static electricity, leading to unstable imaging results, and adding a ground lead to address this problem complicates the device's structure and occupies valuable space.
Innovation Solution
An imaging catheter with a metal wire tube and a retaining ring, where a conductive end of the metal wire is exposed and connected to the tip via the retaining ring, allowing static electricity to be led out without the need for an additional ground lead, thus saving space and reducing structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ground lead is added to the photographing assembly to lead out static electricity, then the stability of picture display is improved, but the structure becomes complicated and space is occupied
Solution Approach 1:
The patent combines the ground lead function with the existing metal wire tube structure. The metal wire tube serves dual purposes: as a protective sheath and as the grounding path for static electricity. This merging eliminates the need for a separate ground lead, thereby improving reliability without increasing structural complexity
Solution Approach 2:
The metal wire tube is designed to perform multiple functions simultaneously: mechanical protection of internal components, electrical grounding for static electricity dissipation, and structural support. This multi-functionality resolves the contradiction by providing grounding capability through an existing multi-purpose component rather than adding a dedicated ground lead
2Reliability
If a ground lead is added to the photographing assembly to lead out static electricity, then the stability of picture display is improved, but valuable space is occupied
Solution Approach 1:
The grounding function is merged into the metal wire tube structure, eliminating the need for additional space-consuming ground lead components. The existing tubular structure serves as the grounding path, thereby maintaining reliability without occupying additional valuable space within the catheter
3Measurement precision
If the photographing assembly is used to image internal conditions, then diagnostic accuracy is improved, but the assembly becomes susceptible to static electricity causing unstable pictures
Solution Approach 1:
The patent converts the harmful effect of static electricity accumulation into a beneficial grounding path. The metal wire tube, which could potentially accumulate static charge, is instead designed to conduct static electricity away from the photographing assembly to ground, thereby eliminating the harmful effect while maintaining the electronic functionality needed for high-quality imaging

AI summary
An imaging catheter and an imaging device relate to a technical field of medical devices. The imaging catheter includes a metal wire tube, a tip and a retaining ring. A metal wire exposed at one end of the metal wire tube forms a conductive end, which is electrically connected with the tip so as to allow the metal wire to be used as a conductive medium to lead static electricity out of the tip, thereby reducing effects of static electricity on a photographing assembly at the tip, and the harm of static electricity to human body. The retaining ring covers the conductive end and is connected with the tip, so as to make the metal wire tube fixedly connected with the tip.
