Recent advancements in fetal surgery have proven that tracheal occlusion in fetuses with congenital diaphragmatic hernia is an effective way to prevent the occurrence of pulmonary hypoplasia. A novel flexible fetoscope with a parallel mechanism structure of a thumbstick to carry on the fetal tracheal balloon occlusion by the targeting and manipulation of the fetal endoscope at a high standard of quick response and dexterity is proposed in this paper. This design is compared with a commercial rigid fetoscope in terms of operation timing and reduced stress to the fetus at neck level. Experiments using a phantom have demonstrated that the flexible fetoscope has a better dexterity and is able to perform stable tracheoscopy and balloon inflation at different levels of the trachea, with the help of a fiberoptic camera.
胎儿手术的最新进展已证明，对于患有先天性膈疝的胎儿，气管闭塞是预防肺发育不全发生的有效方法。本文提出了一种新型柔性胎儿镜，其具有拇指棒的平行机构结构，能够通过胎儿内窥镜的靶向和操作，以高标准的快速响应和灵活性进行胎儿气管球囊闭塞。在操作时机和减轻胎儿颈部压力方面，将该设计与商用刚性胎儿镜进行了比较。使用模型进行的实验表明，借助光纤摄像头，柔性胎儿镜具有更好的灵活性，能够在气管的不同水平进行稳定的气管镜检查和球囊充气。
