This invention provides a spring coil and its preparation method for reducing the risk of damage to the outer wall of a hemangioma. The invention features a novel structural design compared to conventional spring coils. The core characteristic of this structure is that the outer layer is a spring coil body with a secondary structure and a sparse primary structure; that is, the primary coil has a wide spacing between the coil wires, and the interior of the primary coil consists of expandable hydrogel hollow filaments. The sparse structure reduces the excessive pressure on the outer wall of the hemangioma during insertion, preventing rupture. The hollow hydrogel filament structure buffers the pressure exerted on the outer wall of the hemangioma after insertion, avoiding rupture that could worsen the patient's condition or even lead to death.
