Medical Object Mover with Counterforce Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During interventional medical procedures, it is challenging to detect and respond to counterforces exerted on medical objects within hollow organs, leading to potential injuries due to unnoticed resistance and increased frictional forces caused by hydrophilic or hydrophobic coatings, which can result in increased force requirements and risk of perforation.
Innovation Solution
A device comprising a mover device and a sensor unit that detects counterforces and adjusts the movement of medical objects, including a processing unit to compare sensor signals with threshold values, allowing for precise control and reduction of counterforces, and a renewal unit to reduce frictional forces by modifying the surface properties of the medical object.

Engineering Contradiction Analysis
1Reliability
If a sensor unit and processing unit are added to detect and respond to counterforces, then the safety and precision of medical object movement is improved, but the device complexity increases
Solution Approach 1:
The sensor unit is integrated into the mover device before the medical procedure begins, enabling proactive detection of counterforces during medical object movement. The processing unit pre-establishes the relationship between counterforce signals and movement adjustments, allowing immediate response without adding complex real-time decision-making systems.
Solution Approach 2:
The device implements a feedback loop where the sensor unit continuously monitors counterforces exerted on the medical object, and the processing unit automatically adjusts the mover device's movement based on detected counterforce thresholds. This closed-loop feedback system improves safety by enabling real-time adaptation to resistance forces without requiring complex manual intervention systems.
2Speed
If the force required to move the medical object is increased to overcome frictional forces, then the medical object can be moved through the hollow organ, but the risk of injury and perforation increases
Solution Approach 1:
The sensor unit detects counterforces that indicate frictional resistance or potential obstacles during medical object movement. When counterforce exceeds predetermined thresholds, the processing unit automatically adjusts the mover device to reduce applied force, preventing tissue injury and perforation while maintaining adequate movement capability through normal friction.
Solution Approach 2:
The device dynamically changes the movement parameters (force, speed, direction) of the medical object based on real-time counterforce detection. By adjusting these parameters in response to detected resistance, the system maintains effective movement through the hollow organ while preventing force levels that would cause tissue damage or perforation.
