单腋窝和胸前径路达芬奇机器人猪甲状腺切除的对照研究

目的：达芬奇机器人（ da Vinci Si ）外科手术系统下单腋窝切口和胸前径路行猪甲状腺切除术，观察其安全性并积累手术操作经验。方法 da Vinci Si外科手术系统包括医生操控系统、床旁机械臂系统和成像系统。手术器械凭借腋窝/胸壁的切口连接到机器人的机械臂。术者坐于操控台前将手指分别放入操作手柄的指套内联合双脚控制手术器械和双目内窥镜，它可将外科医生的动作转换传递到手术器械的尖端。内置模拟手腕系统（ EndoWrist ）技术可使机械手进行上下左右旋转等7个自由的连续动作，超过了人手在开放手术时的灵活性。本组选用2头小型猪做da Vinci Si外科手术系统不同径路的甲状腺切除动物模型。采用气管插管全身麻醉。结果在da Vinci Si外科手术系统下完成2例不同径路的猪甲状腺切除和胸腺切除术。无中转开放或腔镜手术。手术时间分别为61 min和50 min。结论有开放性甲状腺外科手术经验的专科医师经短期da Vinci Si外科手术系统培训即可实施甲状腺腺叶切除术。在da Vinci Si外科手术系统辅助下行甲状腺切除术的学习曲线短。

Comparison of robotic thyroidectomy through the trans-axillary and the anterior chest approach in a por-cine model

Objective To evaluate the safety of the da Vinci Si surgical system in thyroid surgery and to accumulate operation experience .Methods The da Vinci Si surgical system consists of a surgeon＇s console, a patient-side robotic cart, and high-definition 3D vision system.The robot arm tips were introduced via a single axillary incision or small chest wall ports and attached to the arms of the robot .The surgeon , sitting at the con-sole, manipulated the EndoWrist instruments and endoscope view that transfer the surgeon ＇s movements to the arm tips.The so called EndoWrist＇technology offers seven degrees of movements （ up, down, left, right, twist, et al） , thus exceeding the capacity of a surgeon＇s hand in open surgery .The da Vinci Si surgical system was used to perform thyroidectomy in two small pigs .The animals were intubated and kept anesthetized with halothane .Re-sults Four surgical procedures were done using the da Vinci Si system from beginning to the end , including 2 thyroidectomies and 2 thymectomies .No conversions to open or laparoscopic procedure was used .The procedure length was 61 minutes and 50 minutes, respectively.Conclusions Robotic thyroidectomy can be performed safe-ly by the experienced surgeons after short-term da Vinci Si surgical system training .The learning curve for robotic thyroidectomy is shorter .
