In the medical field, the formation of acute thrombosis in blood vessels, whether cerebral vessels, cardiovascular vessels or peripheral vessels, has the characteristics of high morbidity, high mortality and high disability rate. Aiming at the early intravascular acute thrombosis at home and abroad, the thrombus can be taken, crushed and dissolved by medicaments through an interventional therapy method to ensure that the blood vessel is recanalized, the blood supply of tissues is recovered, and the disability rate and the death rate are reduced.
At present, the clinically adopted intravascular contact thrombolysis methods mainly include the following methods: 1. drug thrombolysis, 2. guide wire thrombolysis, 3. catheter contact thrombolysis. In the practical application process, the methods all have some technical defects: when the medicine is used for thrombolysis, the medicine cannot uniformly and quickly cover all focus parts due to embolism of blood vessels, so that the thrombolysis speed is low. In order to avoid the injury of the blood vessel wall in the guide wire thrombus breaking, the guide wire head is usually made of a softer material, so that the thrombus breaking efficiency is low.
