Background

Vascular interventions imply radiation exposure to the operating physician (OP). To reduce radiation exposure, we propose a novel passive robotic device for fluoroscopy-guided arterial puncturing.

Methods

X-ray dose rates were measured for a total of 30 fluoroscopy-guided puncture femoral arteries in 15 pigs. Fifteen punctures were performed with the device while the other 15 were performed without the device by an interventional cardiologist with 10 years of experience. Parametric t test was used.

Results

The success rate with the device was 100%. Overall, the OP received more radiation (0.41 mSv/h) as compared to the assistant (0.06 mSv/h) (p < 0.001) and, amongst OP’s body parts, hands received more radiation than other body parts (p < 0.001). The radiation dose rate to the OP’s hands during arterial puncturing performed manually without the device was 0.95 ± 0.25 mSv/h whereas it was 0.14 ± 0.006 mSv/h using the device, resulting in an 85% reduction (p < 0.001). For the head, the dose was reduced from 0.16 mSv/h to 0.08 mSv/h (50% reduction, p < 0.001), and for the dominant arm, from 0.12 mSv/h to 0.07 mSv/h (42% reduction, p < 0.001). The fluoroscopy time was reduced from 4.5 ± 0.15 min to 4.3 ± 0.11 min device (p = 0.002).

Conclusions

In a swine model, fluoroscopy time and radiation exposure for the OP puncturing femoral artery were significantly reduced by using the passive robotic device.

在荧光透视引导下的动脉穿刺期间使用被动机器人设备减少操作员的辐射暴露：在猪模型中的一项实验研究。

背景

血管干预意味着放射线会暴露给手术医生（OP）。为了减少辐射暴露，我们提出了一种用于透视引导下的动脉穿刺的新型被动机器人设备。

方法

在15头猪中，通过X射线剂量率测量了总共30部透视引导下的穿刺股动脉。使用该设备进行了15次穿刺，而其他15次在没有该设备的情况下由拥有10年经验的介入心脏病专家进行。使用参数t检验。

结果

该设备的成功率为100％。总体而言，与助手（0.06 mSv / h）相比，OP受到的辐射更多（0.41 mSv / h）（p  <0.001），并且在OP的身体部位中，手部受到的辐射比其他身体部位（p  <0.001）多。在没有使用该装置的情况下手动进行动脉穿刺期间，OP的手的辐射剂量率为0.95±0.25 mSv / h，而使用该装置则为0.14±0.006 mSv / h，导致降低了85％（p  <0.001）。对于头部，剂量从0.16 mSv / h降低至0.08 mSv / h（降低50％，p  <0.001），对于优势臂，剂量从0.12 mSv / h降低至0.07 mSv / h（降低42％，p <0.001）。荧光检查时间从4.5±0.15分钟减少至4.3±0.11分钟（p  = 0.002）。

结论

在猪模型中，使用被动机器人设备显着减少了OP穿刺股动脉的荧光检查时间和放射线照射时间。
