Abstract

The invention discloses a spherical spring ring, and belongs to the technical field of medical instruments, the spherical spring ring comprises an embolism line and a plurality of convex structures arranged on the embolism line, the embolism line and the convex structures are made of degradable materials, the specific surface area of the convex structures is larger than that of the embolism line, the total volume of the protruding structures accounts for 0.01%-1% of the volume of the embolism line, and the protruding structures are arranged on the inner surface and / or the outer surface of the embolism line and / or in gaps between circles. The spherical spring ring is used for treating aneurysm, the automatic forming operation of the spring ring can be achieved through the technology, the working efficiency is improved, and the assembling accuracy is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a spherical spring coil and an automatic production process thereof. Background technique [0002] Coils are medical devices used to treat aneurysms. The distal end of the GDC is a platinum coil, which is connected with a stainless steel guide wire and can be directly inserted into the aneurysm. When direct current is applied, the coil attracts negatively charged blood components (red blood cells, white blood cells, platelets, etc.) Freedom remains within the aneurysm. The GDC coil is extremely soft, and it has good compliance in advancing and retreating in the aneurysm. If the delivery position is not satisfactory, it can be adjusted again, and it is not easy to occlude the parent artery. [0003] When the existing spring coils are processed, they are all assembled manually. The efficiency of manual assembly is low and the error rate of assembly is high, which affects...
