Description

Ultrasonic thrombolysis device

Technical Field

Background

Catheter thrombolysis is effective in treating vascular thrombosis and has become widely accepted and entered clinical guidelines. Catheter thrombolysis most commonly involves placing a drug-releasing catheter in the area of the thrombus and directly infusing thrombolysis drug through the catheter to achieve thrombolysis, which often requires the catheter to be left in the body for several days due to the slow action of thrombolysis drug and thrombus. The prolonged treatment time results in prolonged patient hospitalization and an increased risk of catheter thrombolysis complications. Therefore, the method has important clinical value for improving the thrombolytic efficiency of the medicine and shortening the thrombolytic time.

The role of ultrasonic thrombolysis in thrombus treatment is more and more attracting attention of people, and the ultrasonic thrombolysis is mainly divided into in vitro ultrasonic and in vivo ultrasonic according to the action position of ultrasonic. Research shows that in vitro therapeutic ultrasound (ETUS) assisted thrombolysis can utilize the cavitation effect of ultrasound, so that thrombolytic drugs can enter the interior of thrombus more and more quickly to play a role, and the drug thrombolysis effect is enhanced. The method has the disadvantages that the parameters such as the optimal ultrasonic frequency, the sound intensity and the like of thrombus at different parts in vivo need to be researched by large-scale clinical research because the external ultrasonic wave attenuates when passing through the tissues of the human body and the attenuation degree is different along with the passing tissues. The ultrasonic treatment in vivo utilizes the mechanical vibration effect of the ultrasound, the thrombus removal effect is good, but the thrombus removal effect can be achieved only by adopting high-frequency ultrasound, and the side effect is large.
