A thrombus dredging system for blood vessels

Abstract

A thrombus dredging system for blood vessels. The invention relates to the technical field of medical equipment. A support airbag is fixedly arranged on the outer wall of the right end of the inner tube body; There is a No. 1 rotating shaft, and the front end fixed sleeve of No. 1 rotating shaft is provided with a No. 1 driven bevel gear, and the output end of the drive motor is fixedly connected with a driving bevel gear, and the left side of the driving bevel gear is engaged with the No. 1 driven bevel gear; The fixed sleeve in the middle of the rotating shaft is provided with a knife seat, and the front and rear sides of the knife seat are symmetrically fixed with blades, and the upper and lower sides of the inner tube body are symmetrically opened with through grooves, and the blades are rotated inside the through groove, and the overall operation of the device is simple , the production cost is low, the number of actuators is small, and the volume is small, which is convenient for the removal of thrombus in the blood vessel. At the same time, the device can suck the crushed thrombus out of the body, reducing the probability of secondary thrombus.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a thrombus dredging system for blood vessels. Background technique [0002] Deep vein thrombosis is a venous return disorder caused by abnormal coagulation of blood in deep veins, which often occurs in the lower extremities; and in actual treatment, thrombosis is often secondary to deep vein indwelling, and partial anticoagulant therapy can achieve complete recovery. However, some deep vein thrombosis will eventually become organized, affecting venous return, and even falling off may cause pulmonary embolism, myocardial infarction and cerebral infarction. [0003] Although there are some tools in the prior art that can be inserted into blood vessels for minimally invasive surgery to treat deep vein thrombosis, most of the tools now use mechanical stripping, and the stripped fragments will flow with the blood without being eliminated. In vitro, the probability of reoccu...

[0002] Deep vein thrombosis is a venous return disorder caused by abnormal coagulation of blood in deep veins, which often occurs in the lower extremities; and in actual treatment, thrombosis is often secondary to deep vein indwelling, and partial anticoagulant therapy can achieve complete recovery. However, some deep venous thrombosis will eventually become organized, affecting venous return, and even falling off may cause pulmonary embolism, myocardial infarction and cerebral infarction.

[0003] Although there are some tools in the prior art that can be inserted into blood vessels for minimally invasive surgery to treat deep vein thrombosis, most of the tools now use mechanical stripping, and the stripped fragments will flow with the blood without being eliminated. In vitro, the probability of reoccurrence of venous thrombosis increases. In addition, the existing resection tools have complex equipment and high cost due to many operations. It is beneficial to remove thrombus in blood vessels and needs to be improved urgently
