A system for performing a minimally invasive surgery in a work space inside a body cavity of a patient includes a flexible catheter configured to receive a work instrument therethrough. The flexible catheter has a distal workspace expansion system that includes a first flexible element and a second flexible element that are movable from a non-expanded insertion position to an expanded position to form an expansion zone for expanding a workspace inside the body. The first flexible element and the second flexible element are connected at the distal region with a coupling structure. A stabilization member stabilizes the distal portion of the flexible catheter. 一种用于实施在位于患者体腔内部的工作空间中的微创手术的系统，该系统包括构造成经过其中接纳工作器械的柔性导管。该柔性导管具有位于远侧部的工作空间扩张系统，该工作空间扩张系统包括第一柔性元件和第二柔性元件，这些柔性元件可从非扩张的插入位置移动到扩张位置而形成扩张区用以使在身体内部的工作空间扩张。利用联接结构在远侧区将第一柔性元件和第二柔性元件加以连接。稳定化构件使柔性导管的远侧部稳定。
