Description
Technical field
The invention belongs to vascular diseases therapeutic device technical fields, and in particular to a kind of thrombus acquisition equipment.
Background technique
The people's lives tempo increase in today's society, bad life habits are generally existing, lead to suffering from vascular disease
Crowd's quantity it is more and more.Thrombus be under the pathologic condition of secondary endogenous or extrinsic coagulation system, it is red in blood
The visible components such as cell, blood platelet and fibrin are abnormal aggregation and the blood clotting of formation according to different proportion in the blood vessel
Block.Thrombus is all likely to form in artery and vein blood vessel, is not limited to myocardial infarction, deep vein thrombosis is formed or brain blood
The lesions such as pipe thrombosis, thrombus can also be throughout body tissue's organ, and the intravascular of any position in vivo occurs.
After thrombus is formed in the blood vessels, it will cause vascular occlusion and blood flow be obstructed, cause relevant blood vessel to dominate tissue and lack
Blood, anoxic are even downright bad and generate respective organization, the symptom of organ dysfunction.Early stage mostly uses thrombolytic drug to be treated,
But therapeutic effect is very unobvious, and recanalization rate is low, it is long to lead to the time again, and drug thromboembolism treatment is only applicable to small volume
Thrombus, it is undesirable to the therapeutic effect of large volume embolic occlusion, and only about 3~5% patient is suitble to do drug thrombolysis
Treatment.
Machinery takes bolt to provide a kind of new and effective revascularization treatment method for patient, and this method is that bolt device will be taken defeated
It send to lesion locations, is then taken out thrombus to external by sheath.Machinery takes that bolt operating time is short, related complication is few, is
The research hotspot in thrombus treatment field at present.However it is mostly single-layer bracket structure that the machinery clinically used at present, which takes pin device,
Not only for thrombus to arrest ability weak, need to push and pull repeatedly when taking bolt low efficiency, and operating, lead to thrombus in the blood vessel
Fragment easily falls off and flows to distal vessels, increases the risk of patient vessel's embolism again.
Summary of the invention
To solve the problem of that machinery takes pin device to exist in the prior art, the embodiment of the present invention is designed to provide one
Kind thrombus acquisition equipment, when which works, blood vessel plugging mechanism, thrombus capture mechanism and fragment interceptor structure three match simultaneously
