Wire Guide Pushing Force Tester
The Wire Guide Pushing Force Tester is designed to evaluate the mechanical properties of medical guidewires during advancement. By simulating pushing operations under controlled conditions, the tester measures force-related performance and helps assess guidewire behavior during movement through a simulated pathway.
The instrument supports medical device research and development, production quality control, and process optimization. Test data can help engineers evaluate guidewire performance, identify potential design issues, and improve product consistency. When connected to a vascular simulator, the system can also support assessment of guidewire advancement under simulated use conditions.
