Description
Technical field
The invention belongs to medical instruments field more particularly to a kind of Intravascular Thrombus suction systems.
Background technique
Thrombosis (thrombosis) refers to that under certain condition, blood formed element forms embolus in the blood vessels, makes
At vasculature part or completely plugged, the pathologic process of corresponding site blood supply obstacle.It is small that blood can be divided into according to thrombus constituent
Plate thrombus, red blood cell thrombus, fibrinous thrombus, mixed thrombus etc..Arteriosity thrombus, veins blood can be divided by blood vessel type
Bolt and capillary thrombus.
Thromboembolism (thromboembolism) is that thrombus is fallen off by forming part, during mobile with blood flow
Divide or all block certain blood vessels, causes respective organization and (or) organ ischemia, anoxic, necrosis (arterial thrombus) and extravasated blood, water
The pathologic process of swollen (phlebothrombosis).
The thrombotic diseases as caused by two kinds of pathologic processes of thrombosis and thromboembolism seriously threaten the life of the mankind
Health, disease incidence are in first of various diseases, and due to activity reduction in the work of internet bring, life, thrombotic disease
There are also cumulative gesture in recent years for disease, are one of emphasis and hot spot of contemporary medical science research.
The cause of disease of thrombotic diseases specifically includes that age factor, movable reduction, vascular inflammation etc..Pulmonary embolism (PE) is also known as
Pulmonary thromboembolism is to cause facing for disturbance of pulmonary circulation due to endogenous or exogenous embolus blocking main pulmonary artery or branch
Bed performance and pathologic, physiologic syndrome.Such as further occurrence empsyxis or bad the dead on this basis, i.e. referred to as pulmonary infarction.Postmortem
Data shows the generation age of PE mostly at 50~65 years old, and child morbidity rate is about 3%.And 60 years old or more reachable 20%.90% causes
Dead property PE occurs at 50 years old or more.It is 10 times high in the incidence male more of the same age of the person of women 20~39 years old its deep vein thrombosis, therefore
The incidence of PE is opposite to be increased.In addition because of reasons such as fracture of lower limb, paralysis, severe heart and lung diseases, operations, cause long-term inappropriate
Bed or Healthy People usually limb activity is reduced, reduce the driving force of venous blood flow, also result in stasis of blood stream, it is deep quiet
Arteries and veins thrombosis.
The essential therapeutic arsenals of thrombotic diseases include: the drug therapies such as anticoagulant, anti-bolt, thrombolysis at present, operative treatment with
And interventional therapy etc..It is ineffective through medical treatment to oldness thrombus and Doppler flow mapping forms bad person, it is contemplated that operation is controlled
It treats, that is, removal of thromboses or the excision vascular embolization section of performing the operation simultaneously are coincide again.Interventional therapy passes through conduit by conduit local thrombolysis
Negative-pressure ward thrombus and bolt is taken by the appliance mechanisms formula such as sacculus, bracket.
It after thrombosis, is easy to fall off and with blood flow, partly or entirely blocks certain blood vessels in mobile process, draw
Play respective organization and (or) organ ischemia, anoxic, necrosis etc..Position and the embolism of severity and embolism that thromboembolism influences
Time it is related.
The drug therapies such as anticoagulant, anti-bolt, thrombolysis are needed to entire blood circulation system medication, and dosage is big, slow effect,
Easily cause the complication such as organ internal organs bleeding.
The interventional therapy of thrombolytic drug injection part can be reduced by dose by conduit at present, reduction follows entire blood
The influence of loop system, but still there are slow effect.
Thrombus especially fresh thrombus is easily broken as jelly without mechanical strength in vivo in vivo.It is taken by sacculus
Bolt needs to block Distal blood flow, in order to take bolt complete as far as possible, takes bolt sacculus to need adherent, is easy to scratch blood vessel when moving, lead to
Bracket is crossed to take bolt that thrombus is easy to cause to rupture and take bolt incomplete.
Conduit negative-pressure ward thrombus includes manual suction and Bernoulli effect by Biochemical analyzer to external at present.Suction manually
Unstable and suction force is small, almost without clinical efficacy.It is aspirated using Bernoulli effect, the course of work is that transfer tube generates arteries and veins
Physiological saline is injected through conduit and washes away thrombus from the hole contra-injection of conductor housing end side by stamping press, and high speed physiological saline produces simultaneously
Raw local depression area, is sucked out the embolic particles of fragmentation by conduit tap.The disadvantage of this method is that by Biochemical analyzer
To it is external while, blood is also pumped in vitro together, and blood volume in patients is caused to reduce.
Summary of the invention
