Image Intensifier Coupling Mechanism for Medical Device Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image intensifier systems lack the capability to actively guide the placement of objects near or adjacent points of interest in medical procedures without obstructing the image generation process or distorting the images.
Innovation Solution
An apparatus with a coupling mechanism that attaches to the image intensifier, featuring an object holding mechanism visible in the image, allowing precise alignment and movement along or around the intensifier's central axis, while minimizing visibility of the coupling mechanisms to prevent image distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a coupling mechanism is attached to the image intensifier to guide object placement, then the capability to actively guide object placement is improved, but the image clarity and accuracy deteriorate due to obstruction and distortion
Solution Approach 1:
The coupling mechanism is designed with differential visibility properties: the first coupling mechanism (attached to the image intensifier) is substantially not visible in the image, while the second coupling mechanism (with object holding mechanism) is visible. This local differentiation allows the system to provide guidance functionality where needed while maintaining image clarity in critical areas.
Solution Approach 2:
The coupling mechanism is divided into two distinct segments: a first coupling mechanism for attachment to the image intensifier that remains invisible in the image, and a second coupling mechanism with object holding capability that is visible. This segmentation allows each part to serve its specific function without compromising the other, resolving the contradiction between guidance capability and image clarity.
2Ease of operation
If the object holding mechanism is made visible in the image for guidance, then the guidance capability is improved, but the image distortion increases
Solution Approach 1:
The second coupling mechanism is designed to be visible in the image to provide guidance, but only to the extent necessary for alignment purposes. The visibility is localized to the orientation indication features, while minimizing the overall visible footprint of the mechanism to reduce image distortion.
Solution Approach 2:
The coupling mechanisms incorporate orientation indications that are visible in the image, using visual contrast or specific radiographic properties to indicate orientation without causing significant distortion. This allows the guidance function to be achieved through targeted visibility of critical alignment features.

AI summary
An apparatus and a method for guiding the placement of an object to a desired location based on an image generated by an image intensifier where the apparatus includes a first coupling mechanism that is configured to be releaseably attachable to one of the transmitter and receiver of the image intensifier and a second coupling mechanism that is coupled to the first coupling mechanism and includes an object holding mechanism, the object holding mechanism is configured to releaseably hold the object and where at least a portion of the second coupling mechanism is visible in the image generated by the image intensifier when the apparatus is attached to the image intensifier.
