Problems solved by technology

[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 a...

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] see as Figure 1-Figure 6 As shown, the technical solution adopted in this specific embodiment includes an inner pipe body 1, an air guide main pipe 2 and an outer conduit 4; It is fixedly connected with the main air pipe 2, and the main air pipe 2 is made of medical-grade PP hose. The outer end of the main air pipe 2 is connected to the external air pump, and the inner end of the main air pipe 2 is fixedly connected with a plug 3 by hot melting. , the outer movable sleeve of the main gas pipe 2 is provided with an outer catheter 4, and the outer catheter 4 adopts a medical-grade flexible pipe; it also includes a thrombus crushing mechanism 10, a support air bag 5, an air guide branch pipe 6, and a slag suction pipe 7; The outer wall of the right end of the tube body 1 is fixed with a support air bag 5 by gluing. One end is communicated with the air guide main...

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...
