Description

Cranial nerve and blood vessel spring coil conveying device

Technical Field

The utility model relates to the technical field of spring coil devices, in particular to a cerebral neurovascular spring coil conveying device.

Background

Hemangiomas, particularly cerebral hemangiomas, are thin walled and open to arterial blood vessels, and once the hemangioma ruptures, the patient is at risk for life. For such lesions, surgical treatment carries a great risk. Currently, interventional therapy is mainly performed by using a spring ring. The existing spring ring is mainly an electrolytic release spring ring. The representative products are electrolytic disentangling coils such as GDC, Matrix, Nexus, Jasper and the like. The spring ring is connected with the conveying conduit by mainly utilizing an electric welding technology. After the electric welding is cooled, the welded portion is not uniform, and thus the pressure required for electrolysis is not uniform, so that the final electrolysis time is not uniform, ranging from the shortest 30s to the longest dozens and several minutes.
