Thrombus dredging system for blood vessels

Abstract

The invention relates to a thrombus dredging system for blood vessels, and relates to the technical field of medical equipment. A supporting air bag is fixedly arranged on the outer side wall of the right end of an inner tube body; a residue suction tube is arranged in the middle of an air guide main tube; the middle of the inner tube body is rotationally provided with a first rotating shaft through a bearing; the front end of the first rotating shaft is fixedly sleeved with a first driven bevel gear; the output end of a driving motor is fixedly connected with a driving bevel gear; the left side of the driving bevel gear is meshed with the first driven bevel gear; the middle of the first rotating shaft is fixedly sleeved with a knife holder; blades are symmetrically and fixedly arranged atthe front side and the rear side of the knife holder; through grooves are symmetrically formed in the upper side and the lower side of the inner tube body; and the blades are rotationally arranged inthe through grooves. The device is simple in overall operation, relatively low in production cost, few in execution mechanism and relatively small in volume, and can conveniently remove thrombus in blood vessels; meanwhile, the device can suck crushed thrombus and discharge the thrombus out of a body; and the probability of secondary thrombus is reduced.

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
