The present invention provides a developable core-shell surgical suture, a preparation method thereof and an occluder, belonging to the technical field of developable surgical suture manufacturing. The preparation method of the developable core-shell surgical suture comprises the following steps: mixing a developer and a first polymer material to form a core material, wherein the difference between the melting point of the developer and the melting point of the first polymer material is ≤30°C; respectively adding the core material and a second polymer material into corresponding chambers of a twin-screw extruder, and sequentially performing extrusion, wire drawing and cooling shaping to obtain the developable core-shell surgical suture, which has ideal developability and mechanical properties.
