OBJECTIVE
The purpose of this study was to detect the incidence, prevalence, and location of insulation failures (IFs) in laparoscopic and robotic instruments.
STUDY DESIGN
In phase A, a total of 78 robotic and 298 laparoscopic instruments were tested at 20 W and 2.64 kV at Mayo Clinic in Arizona. In phase B, 60 robotic and 308 laparoscopic instruments were tested at 20 W/1 kV and 20 W/4.2 kV, respectively.
RESULTS
In phase A, the robotic group showed a higher prevalence (25/78; 32%) and incidence of IFs after 10 uses (35/44 instruments; 80%) when compared with laparoscopy (prevalence, 39/298 [13%]; incidence, 68/189 [36%]; P<.05). In phase B, IFs were detected in 81.7% of the robotic instruments and in 19.5% of the laparoscopic instruments (P<.005).
CONCLUSION
There is a high incidence and prevalence of IF in endoscopic instrumentation that is more common in the robotic group.
目的
本研究旨在检测腹腔镜和机器人器械中的绝缘故障（IFs）的发生率、患病率和位置。
研究设计
在 A 阶段，亚利桑那州梅奥诊所共检测了 78 个机器人器械和 298 个腹腔镜器械，测试电压为 20 W 和 2.64 kV。在 B 阶段，分别以 20 W/1 kV 和 20 W/4.2 kV 对 60 个机器人器械和 308 个腹腔镜器械进行了测试。
结果
在 A 阶段，与腹腔镜相比，机器人组在 10 次使用后显示出更高的患病率（25/78；32%）和 IFs 发生率（35/44 器械；80%）（患病率，39/298[13%]；发生率，68/189[36%]；P<.05）。在 B 阶段，在 81.7%的机器人器械和 19.5%的腹腔镜器械中检测到 IFs（P<.005）。
结论
内镜器械中的 IF 发生率和患病率都很高，在机器人组中更为常见。
