Abstract

The invention relates to a pulmonary artery thrombus treatment platform which comprises a suction catheter, a thrombus breaking device and a suction pump, wherein the thrombus breaking device comprises one or more of a first thrombus breaking assembly, a second thrombus breaking assembly and a third thrombus breaking assembly; the first thrombus breaking assembly comprises a first catheter I, a first catheter II and a first stirrer; the first stirrer comprises a plurality of mesh baskets which are sequentially arranged along the axis of the first catheter, and the maximum diameters of the meshbaskets are sequentially reduced from the far end to the near end when the mesh baskets are in an open state; the second thrombus breaking assembly comprises a second catheter II, a second catheter II and a second stirrer; the second stirrer is linear and is bent in an open state; the third thrombus breaking assembly comprises a third catheter I, a third catheter II and a third stirrer; and the third stirrer is sheet-shaped and is bent in an open state. The pulmonary artery thrombus treatment platform can remove pulmonary artery thrombus under the condition that relative safety is guaranteed,and is particularly suitable for removing thrombus at pulmonary artery and capillary bifurcation positions.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a treatment platform for pulmonary artery thrombus. Background technique [0002] Pulmonary embolism (PE) is a potentially life-threatening disease and one of the leading causes of death in hospitalized patients. In the United States, nearly 600,000 patients experience symptomatic PE each year, of which 200,000 are fatal PE. The mortality rate of patients diagnosed with PE is 15% to 22%. PE is mainly caused by the shedding of venous thrombosis in the lower extremities. PE and deep venous thrombosis (DVT) are considered to be manifestations of the same disease in different parts, and are collectively referred to as venous thromboembolism (VTE). According to a study conducted by the Vascular Surgery Center of Beijing Shijitan Hospital, PE occurred in 45% of DVT patients, and fatal PE occurred in 4%. Anticoagulation is the main method for the treatment of VTE. When ant...
