Solution Overview
Problem
Existing mounting systems for magnetic field generators in electroanatomic mapping procedures are cumbersome and require tools, making re-positioning difficult and disruptive to patients, and often interfere with magnetic fields and fluoroscopy imaging.
Innovation Solution
A mounting assembly with extendable arms, tensioning means, and side rails that securely attach to a patient table, allowing easy re-positioning of the magnetic field generator without disturbing the patient, using non-magnetic and x-ray translucent materials to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting system securely attaches the magnetic field generator to the patient table, then the generator remains stable during procedures, but re-positioning becomes difficult and requires tools
Solution Approach 1:
The mounting system employs dynamic components including telescoping arms with adjustable lengths and spring-loaded locking mechanisms that allow the generator to be securely attached and easily re-positioned. The arms can extend and contract to accommodate different table configurations while maintaining secure attachment through incremental locking positions.
Solution Approach 2:
The mounting system is divided into separate functional segments: telescoping arms for positioning, locking mechanisms for security, and attachment interfaces for the table. This segmentation allows each component to perform its specific function independently, enabling secure attachment while maintaining ease of re-positioning through simple operational steps.
2Reliability
If traditional mounting systems are used, then the magnetic field generator can be attached to the table, but the materials interfere with magnetic fields and fluoroscopy imaging
Solution Approach 1:
The mounting system utilizes composite material construction, specifically aluminum alloy frames combined with carbon fiber components. These materials provide the necessary structural strength for secure attachment while being non-magnetic and radiolucent, thereby eliminating interference with magnetic fields and fluoroscopy imaging procedures.
Solution Approach 2:
Different portions of the mounting system use different materials optimized for their specific functions: aluminum alloy for structural framework requiring strength, carbon fiber for components near the magnetic field source requiring non-magnetic properties, and radiolucent materials for areas in the imaging path. This local quality approach ensures attachment capability while minimizing interference.
3Productivity
If the mounting system is designed for easy re-positioning without disturbing the patient, then procedural efficiency improves, but the attachment security may be compromised
Solution Approach 1:
The mounting system incorporates pre-configured quick-release latches and pre-tensioned spring mechanisms that are prepared in advance. This allows the operator to quickly release and re-position the generator by simply actuating the latches without requiring complex tool operations, thereby improving procedural efficiency while maintaining secure attachment during normal operation.
Solution Approach 2:
The spring-loaded locking mechanisms automatically engage and disengage based on the position of the telescoping arms. When the arms are adjusted to the desired position, the springs automatically lock them in place, providing secure attachment without requiring additional fastening operations. For re-positioning, simply releasing the quick-release latches allows the springs to move the arms to a neutral position, enabling easy reconfiguration.
