The invention provides a degradable medical spring ring, which comprises a bare metal spring ring body, wherein the bare metal spring ring body is prepared from magnesium or magnesium alloy materials. The technical defects are overcome. The magnesium or magnesium alloy is used as a biodegradable material to be applied to a medical spring ring. The magnesium element is an indispensable element in the process of maintaining the normal metabolism process of the human body; the elements of the medical spring ring after the degradation can be used by the human body; the stable concentration of the elements can be maintained by the kidney and the small intestines; meanwhile, the elements can be completely degraded after the safe period; no residue is left; the space occupying effect is avoided; the influence of metal artifacts on the later-stage radiographic follow-up visit can be avoided; and the use value is high.
