我们开发了一种新一代器械，称为多穿刺手术（MPS）的刚性-柔性外鞘，以解决自然腔道经腔内镜手术（NOTES）中的组织闭合、三角测量和平台稳定性问题，以及针镜手术（NS）中视野受限、器官损伤和从体内取出切除器官的问题。柔性外护套的形状可以通过新颖的气动形状锁定机构选择性地锁定。主要特征包括远端的四个方向屈曲、四个工作通道以及抽吸和喷水功能。原型的插入部分长330 mm，最大外径为25 mm。外鞘系统已成功地在猪胃部分切除术中进行了体内实验。先进的外鞘系统已显示出解决NOTES和NS问题的巨大潜力。
We have developed a new generation device called rigid-flexible outer sheath with multi-piercing surgery (MPS) to solve the issues of tissue closure, triangulation, and platform stability in natural orifice transluminal endoscopic surgery (NOTES), and the problems of restricted visual field, organ damage, and removing a resected organ from body in needlescopic surgery (NS). The shape of the flexible outer sheath can be selectively locked by a novel pneumatic shapelocking mechanism. Major features include four directional flexion at the distal end, four working channels, and suction and water jet functions. The insertion part of the prototype is 330 mm long with a 25 mm maximum outer diameter. The outer sheath system has successfully preformedin vivoexperiment using a swine on partial gastrectomy. The advanced outer sheath system has shown great promise for solving NOTES and NS issues.
