Abstract

The invention provides a thrombolysis promoting module and an interventional thrombus removing device. The thrombolysis promoting module comprises a driving module which is configured to generate first energy so as to drive a microbubble precursor to penetrate into thrombus; and a cavitation module which is configured to generate second energy to generate cavitation in or on the surface of the microbubble precursor penetrating into the thrombus to form microbubbles, the second energy being different from the first energy. The interventional thrombus removing device comprises at least one thrombolysis promoting module of the embodiment; and a main catheter which defines a lumen and includes a distal portion housing the thrombolysis promoting module and configured to release the microbubble precursor within the lumen out of the main catheter. The microbubble precursor and a thrombus removing medicine can be driven to permeate into the thrombus, the microbubble precursor permeating into the thrombus or the surface of the microbubble precursor can be cavitated to form microbubbles, the contact area of the thrombus removing medicine and the thrombus is increased, and therefore thrombolysis is promoted, the thrombus removing efficiency is effectively improved, and the operation is safe and efficient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an interventional thrombus removal device and a thrombolytic promoting module. Background technique [0002] Cardiovascular and cerebrovascular embolism is one of the main diseases that endanger human life and health, and deep venous thrombosis (DVT) greatly affects the health and quality of life of patients. At present, the commonly used clinical methods for the treatment of thrombosis include drug thrombolysis, vascular stent, mechanical rotary cutting, ultrasonic thrombolysis, etc., but these methods have certain defects. Therefore, there is an urgent need for a safer and more efficient invasive thrombectomy device. Contents of the invention [0003] In order to solve the problems pointed out by the above-mentioned background technology, an embodiment of the present invention provides a thrombolysis-promoting module and an interventional thrombus removal device. ...
