Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to an ultrasound-assisted thrombus aspiration and removal device. Background Art

[0002] Thrombosis is a common clinical condition. Its formation often leads to peripheral vascular occlusion and, in severe cases, dangerous diseases such as ischemic stroke, myocardial infarction, and pulmonary embolism, severely endangering human life and health. Existing thrombus removal methods, such as drug thrombolysis, balloon angioplasty, and surgical thrombectomy, all have significant drawbacks. Surgical thrombectomy can cause significant trauma to the patient, while drug thrombolysis can often lead to complications such as nerve damage and intramural bleeding due to excessive dosages of thrombolytics.

[0003] Studies have shown that applying ultrasound to catheter-directed thrombolysis (CDT) can enhance the thrombolytic effect of drugs. By leveraging the mechanical and cavitation effects of ultrasound, it increases drug penetration into the clot, broadens the contact area between the drug and the clot, and accelerates clot dissolution. Ultrasound thrombolysis boasts high thrombolytic efficiency and excellent safety. It can also significantly reduce the dosage of thrombolytic drugs, significantly reducing the risk of complications such as intratissue bleeding and neurological damage.

[0004] Thrombolysis solely using the mechanical vibration effect of ultrasound is often inefficient, requires prolonged treatment, and can easily cause bleeding symptoms. Thrombus removal using negative pressure aspiration alone is often ineffective for subacute or chronic thrombi. Therefore, there is an urgent need for an ultrasound-assisted thrombus aspiration device to improve thrombus removal efficiency. Utility Model Content

[0008] Optionally, a gas filter is provided on the suction pipeline between the negative pressure regulator and the suction connector, and the gas filter filters the gas entering the suction pipeline through the suction connector.
