目的
评估不同穿刺经验操作者在穿刺机器人辅助超声引导下经皮穿刺体外模型实验中的准确性和可行性。
方法
2 位不同年资的医师分别通过穿刺机器人辅助系统和徒手对甲状腺结节体模中的目标进行穿刺实验,每人分别做10 次穿刺。采用t 检验对比2 种穿刺方式的穿刺针尖定位误差、针轴角度误差以及操作时间的差异,并采用组内相关系数(ICC)分析不同年资医师使用穿刺机器人辅助系统进行穿刺实验的一致性。
结果
机器人辅助比徒手穿刺精准度更高,但操作时间更长,两者针尖定位误差为(0.62±0.26)mm vs (1.29±0.38)mm,针轴角度误差为(1.04±0.63)°vs (2.01±0.86)°,平均操作时间为(26.45±12.44)s vs (20.58±9.86)s,差异均具有统计学意义(t=9.187、P<0.001;t=3.409、P=0.003;t=-2.289、P=0.034)。不同经验的操作者利用机器人辅助系统穿刺,在针尖定位误差和操作时间上均具有极佳的一致性[ICC(95%可信区间)=0.783(0.126~0.946)、0.903(0.610~0.876)]。
结论
与徒手穿刺相比,使用机器人辅助系统穿刺具有更高的准确性及稳定性,但使用机器人辅助系统增加了操作时间。

Objective
To assess the accuracy and feasibility of ultrasound-guided robot-assisted percutaneous puncture.
Methods
Two physicians with different years of experience conducted ultrasound-guided puncture experiments on thyroid nodule phantoms using both the puncture robot-assisted system and manual puncture, each for 10 times. The puncture needle positioning error, directional error, and total operation time were recorded. Additionally, the consistency among physicians with different experience levels when using the puncture robot-assisted system for puncture was assessed.
Results
The robot-assisted group demonstrated higher puncture accuracy than the manual group, but with longer operation times. The average needle tip error in the robot-assisted group versus the manual group was (0.62±0.26) mm vs (1.29±0.38) mm, the average needle axis angle error was (1.04±0.63)° vs (2.01±0.86)°, and the average operation time was (26.45±12.44) s vs (20.58±9.86) s;the differences were statistically significant between the two groups ( t=9.187, P<0.001; t=3.409, P=0.003;t=-2.289, P=0.034). Operators with different experiences using the robot-assisted system for puncture showed good consistency in needle tip error and operation time, with intraclass correlation coefficient (95% confidence interval) values of 0.783 (0.126-0.946) and 0.903 (0.610-0.876), respectively (P<0.05).
Conclusion
Compared to manual puncture, the robot-assisted system exhibits higher accuracy and stability in ultrasound-guided thyroid nodule puncture procedures. However, the use of the robot-assisted system increases the operation time.
