The invention relates to a spring coil and a preparation method thereof. The coil includes a degradable embolic coil, a developing coil arranged in the embolic coil, and a plurality of inducing units arranged on the embolic coil, the inducing units are used for inducing vascular cells to adhere to the embolic coil. The multiple inducing units on the embolic coil of the coil can induce vascular cells to adhere to the embolic coil, so compared with the existing coils, the coils of the present application are more likely to cause vascular cell adhesion, and realize the human body under the action of vascular cells. The active degradation of embolic coils can greatly shorten the degradation cycle of embolic coils, avoid long-term safety hazards after implantation and can completely remove the mass effect, and can also solve the matching between the degradation cycle and the disease cure cycle caused by individual differences in different patients problem of poor sex.
Description
Technical field [0001] The present invention relates to the field of medical devices, and in particular, to a spring ring and a preparation method thereof. Background technique [0002] With the improvement of domestic living standards and the advancement of medical diagnosis technology, the incidence of vascular disease caused by the abnormal changes or aging of the blood vessels is also increased year by year, including intracranial aneurysms, internal organs, peripheral aneurysms , Arterythromic deformity and hemangioma, etc. For such diseases, treatment options taken at home and abroad mainly include two types of surgical treatment and interventional treatment. Due to the huge trauma and a series of complications, a series of complications that may bring in surgical treatment, the intravascular interventional minimally invasive treatment is the preferred solution for the treatment of the above vascular disease. Among them, the spring loop is one of the important implants of t...
