主从式遥操作血管介入机器人

Master-Slave Remote Controlled Vascular Interventional Robot

传统的血管介入手术需要医生徒手操控导管,存在医生受辐射和人为因素影响手术质量等弊端.针对该问题,设计了用于辅助医生手术的主从式遥操作血管介入机器人.根据临床手术的要求,基于模块化理念,分别对机器人的从端推进机构、主端操控装置进行了结构设计,为主从模式的实现做了相关的软、硬件开发;对机器人样机进行了必要的性能测试,证实了该机器人具有小于1 mm的运动控制精度和0.44 ms的主从运动实时性.结果表明:该机器人系统解决了传统手术中的问题,在功能和性能上完全满足血管介入手术的要求,具有较高的临床使用价值.

Catheter should be controlled by doctor＇ s hands during the traditional vascular interventional surgery which had some disadvantages, as the doctor absorbed radiation and operation quality was affected by human factors. To solve the problem, master-slave remote controlled vascular interventional robot assisting doctor was designed. According to the requirements of clinical surgery, the subordinate feed mechanism and master operational device were designed respectively on the basis of the modular concept, the hardware and software were developed to achieve the master-slave mode. The necessary performances were tested, the motion control accuracy of less than 1 mm and the master-slave real-time motion of 0.44 ms were confirmed. The results showed that the robot system can solve the problems of traditional surgery, and meet the requirements of vascular interventional surgery on function and performance, which has high value for clinical application.
