The invention provides a mesh spring ring. The mesh spring ring comprises a metal mesh sleeve and a spring. The spring is sleeved with the metal mesh sleeve, and the inner diameter of the metal mesh sleeve is larger than the outer diameter of the spring. The metal mesh sleeve is a memory alloy mesh. A metal core is arranged in the spring in a penetrating mode. The metal core and the metal mesh sleeve are fixed to the two ends of the spring. The mesh spring ring is used for replacing an existing spring ring structure, the embolism effect is enhanced to a large degree through an expanded mesh shape, the filling rate is low, meanwhile, the weight of fillers is lowered, arterial aneurysm is prevented from oppressing surrounding nervous tissue, the mesh hole structure has the good flexibility and elasticity, and can be attached to the wall of the arterial aneurysm well after being released in a tumor cavity, and the mesh hole structure is stably placed in the arterial aneurysm and cannot fall off. Meanwhile, certain mechanical strength can be achieved in the conveying process through the spring in the spring ring in the metal mesh sleeve, the spring ring has good mechanical conduction, and the shape and position of the mesh spring ring can be displayed under X rays.
