Thrombus treatment platform

Abstract

The invention relates to a thrombus treatment platform. The thrombus treatment platform comprises a suction catheter with a suction channel, a suction pump communicated with the near end of the suction catheter, a stirring device and a filter screen assembly, and the filter screen assembly comprises a filter rod and a filter screen; the stirring device comprises a first catheter, a second catheter slidably arranged outside the first catheter in a sleeving mode, a stirrer arranged at the far end of the first catheter and having an open state and a closed state, and an operating device arranged between the first catheter and the second catheter and capable of relatively sliding the first catheter and the second catheter so as to enable the stirrer to be switched between the open state and the closed state; and the thrombus treatment platform further comprises a driving device which is connected with the first catheter or the second catheter and can drive the stirrer to rotate. The thrombus treatment platform can remove thrombus while ensuring relative safety, and is especially suitable for removing a large number of thrombus in inferior vena cava, protecting venous valve and venous vessel wall, has controllable blood loss and simple operation steps, shortens operation time and reduces hospitalization cost of patients.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a thrombus treatment platform. Background technique [0002] Thrombotic diseases include arterial thrombosis, venous thrombosis, and thromboembolism. Existing treatments mainly include vascular thrombectomy, catheter contact thrombolysis, and percutaneous mechanical thrombectomy. Surgery requires anatomical separation and incision of blood vessels, such as femoral artery, femoral vein or brachial artery incision, etc. With the development of endovascular interventional technology and the innovation of materials, this open surgical method is gradually replaced by minimally invasive interventional endovascular treatment , that is, catheter contact thrombolysis and percutaneous mechanical embolectomy. Due to the high bleeding risk of thrombolytic drugs and extremely strict indications for catheter-based thrombolysis, a large proportion of patients have contraindications f...

Problems solved by technology

However, too long negative pressure time often leads to excessive blood loss in patients, and high-pressure rapid stirring may cause red blood cell damage and lead to hemolysis, which may easily lead to the occurrence of sequelae of thrombectomy
