导管操作系统中力觉传感器信息的获取与控制研究

摘要

In catheter operating system, acquisition and control for force feedback of force sensors have been studied,the top force of catheter is measured using fiber-optic sensor. The force of catheter wall is measured by micro force sensor based on PVDF material. The catheter operating system monitors output information of force sensors, and a novel lord-from catheter operating system with force information monitoring is achieved. Experimental results show that the system can realize the feedback of the force information of sensors very well.%针对导管操作系统中力觉传感器反馈力的获取与控制进行了研究,导管前端采用光纤力传感器测量导管的顶端力；导管侧壁采用基于PVDF材料开发的微力传感器来测量导管的侧壁力.该导管操作系统对力觉传感器的输出信息进行了监测,实现了一种带有受力信息监测的主-从模式的新型导管操作系统.实验结果表明:该系统能够较好地实现受力信息的反馈.
