We analyzed the electrical characteristics of the da Vinci system's low-power monopolar coagulation mode with an electrocautery analyzer to determine its suitability as an alternative to monopolar soft coagulation mode. The voltage at the plateau of the power limit between 15 and 16 W and between 23 and 24 W of the forced coagulation mode of the da Vince system was close to that of the effect 8 and 10 of the soft coagulation mode, respectively. Experiments using chicken meat and an infrared thermographic camera confirmed the safety and effectiveness of low-power monopolar coagulation mode showing no carbonization at temperatures below 90 °C. In 73 robotic-assisted lung resection using low-power coagulation mode, no electric spark or carbonization was observed and all cauterizations were similar to soft coagulation mode. In conclusion, Forced coagulation mode of the da Vinci system can be used as an alternative to monopolar soft coagulation mode with appropriate effect and power limit settings.
我们用电灼分析仪分析了达芬奇系统低功率单极凝血模式的电气特性，以确定其作为单极软凝血模式替代方法的适用性。达芬奇系统强制凝血模式在15至16瓦以及23至24瓦功率限制平台处的电压分别接近软凝血模式效果8和10时的电压。使用鸡肉和红外热像仪进行的实验证实了低功率单极凝血模式的安全性和有效性，在90°C以下的温度下未出现碳化现象。在73例使用低功率凝血模式的机器人辅助肺切除手术中，未观察到电火花或碳化现象，所有烧灼操作均与软凝血模式相似。总之，达芬奇系统的强制凝血模式在设置适当的效果和功率限制时可作为单极软凝血模式的替代方法。
