BACKGROUND The purpose of this study was to develop a remote-controlled injection device for T-tube cholangiography to avoid occupational exposure. MATERIAL AND METHODS The remote-controlled injection device has 3 major components: an injection pump, a pressure sensor, and a wireless remote-control panel. The feasibility and effectiveness of this device for T-tube cholangiography was evaluated in ex vivo porcine livers using a laparoscopic training platform and in in vivo canine experiments. RESULTS The contrast dye was successfully injected into the biliary tracts of the ex vivo porcine liver and canines by the designed device. The X-ray images clearly showed the anatomical structure of the bile ducts. No obvious adverse reaction was observed in the dogs during or after the procedure. All steps were controlled remotely, avoiding ionizing radiation exposure to the surgeons. CONCLUSIONS This novel remote-controlled injection device for T-tube cholangiography can assist operators in completing cholangiography remotely and protecting them from occupational exposure.
本研究旨在开发一种用于 T 管胆管造影的遥控注射装置，以避免职业暴露。
遥控注射装置有 3 个主要组成部分：注射泵、压力传感器和无线遥控面板。使用腹腔镜培训平台在离体猪肝和犬体内实验中评估该设备用于 T 管胆管造影的可行性和有效性。
设计的设备成功将造影剂注入离体猪肝和犬的胆道。X 射线图像清晰显示了胆管的解剖结构。在手术过程中和手术后，犬没有出现明显的不良反应。所有步骤都可以远程控制，避免了外科医生受到电离辐射。
这种新型的 T 管胆管造影遥控注射装置可以帮助操作人员远程完成胆管造影，并保护他们免受职业暴露。
