Technical Field

[0001] The invention relates to the technical field of thrombus treatment, in particular to a thrombus aspirating device for clinical vascular surgery. Background Art

[0002] Thrombosis treatment is divided into drug treatment and surgical treatment. For patients with severe thrombosis, surgical treatment is usually used to extract the severe thrombus in the blood vessels so that the blood circulation inside the blood vessels can return to normal. When performing surgical treatment on patients, a thrombus extraction device is required to extract the thrombus blocked in the blood vessels and discharge it from the body.

[0003] When performing surgical treatment on patients, a thrombus aspiration device is needed. Among them, the "A Clinical Vascular Surgery Thrombus Aspiration Device" disclosed in the application number "CN113598877A" has solved the problem that the existing surgical operations use angiography technology in combination with access to minimally invasive treatment channels for direct aspiration.
