Abstract: Disclosed are an expandable serpentine carrier with variable rigidity for natural orifice transluminal endoscopic surgery and a method for using the serpentine carrier. The serpentine carrier is mainly formed of woven tubes and a hot-melt adhesive, the variable rigidity function thereof relies on changing the state of the hot-melt adhesive, and the degree of change in size relies on the property of the woven tubes themselves and is realised by wire driving.The provided expandable serpentine carrier with variable rigidity for natural orifice transluminal endoscopic surgery has excellent flexibility, can realise large curvature bending, has a stronger capability for adapting complex human orifice environments, and after entering a human body, is supported by a driving wire, having a large diameter state for opening human tissue, providing a larger orifice pathway. After having a large diameter, the two states of rigidity and flexibility can be changed by controlling heat input and output, which can protect a human orifice subjected to a surgical instrument from stab or cutting wounds and provide support to the instrument, increasing stability and improving surgical precision.
