The utility model belongs to medical instruments field, and in particular to a kind of intervention thrombus removing conduit.
Background technique
With the improvement of living standards, thrombotic diseases disease incidence is increasing, arterial blood can be divided into according to happening part
Bolt and phlebothrombosis.When human vas is damaged, start clotting mechanism, forms blood clot (i.e. thrombus) and " block " notch, with
Avoid Excessive bleedings.Later, anticoagulant mechanism starts, and thrombus is inhibited to be excessively formed, and gradually dissolves existing thrombus, makes thrombus will not
Ceaselessly increase, and be able to be removed in time, enables blood proper flow in the blood vessels, neither formation thrombus, also do not go out
Blood.But, under the action of a variety of factors, this balance can be broken.If clotting mechanism occupies " advantage " status, will lead
Cause thrombus that can not eliminate.Even antegrade blood flow is mobile, and incarceration is lacked to the blood vessel at other positions so as to cause respective organization, organ
Blood or necrosis lead to various thrombus related diseases, including big well known myocardial infarction, cerebral apoplexy etc..Thrombus is related
Disease, severely compromises the health of people, nowadays occupies lethal and first the reason that disables.
It solves the problems, such as thrombus, generallys use various thrombus remove devices, such as take out thrombus using negative-pressure ward principle
It can be led to extravascular thrombus suction catheter, catheter proximal end equipped with spiral cutter with the thrombectomby pumped out again after rotary-cut thrombus

Specific embodiment
The technical solution of the utility model is described in more detail with reference to the accompanying drawings and examples.These are said
The bright feature and advantage for being merely illustrative the utility model, rather than limit the protection scope of the utility model.
As shown in Figure 1, the utility model has the whole crossover thrombus removing conduit of broken thrombus and pumping function total
Body length is 1500mm, can be used for the removing of thrombus in coronary artery or peripheral artery vein.The branch pipe of Y type luer connector connects
Drug injection mouth 2 and drug injection chamber 13, Y type luer connector supervisor connection be filament guiding seat 1 and guidewire lumen 14.Seal wire
Chamber 14 and drug injection chamber 13 are coaxial, and the two passes through Y type haemostatic valve and reaches distal end of catheter 7, and Y type haemostatic valve is equipped with pump orifice 4
It is connect with suction chamber 12, pump orifice 4 can connect the device or tool of negative-pressure ward.Suction chamber 12, drug injection chamber 13, guidewire lumen
14 3 chamber channels are independent, and coaxial.
As shown in Fig. 2, in use, guidewire lumen 14 and drug injection chamber 13 are pushed out set by promoting Y type luer connector
Pipe 6.13 distal end of drug injection chamber is made of 2~10 capillaries 10 and several lousiness 11, and capillary 10 and lousiness 11 uniformly divide
Cloth is on 14 outer wall of guidewire lumen.When not having the constraint of casing 6, capillary 10 and 11 end vertical of lousiness are in guidewire lumen 14, vertically
Height is 0.5~5mm, this segment length is 5~50mm, and can be rotated as filament guiding seat 1 reverses.14 head end of guidewire lumen is solid
Determine developing mark 9, developing mark 9 can be the resin of precious metal alloys or tungstenic.When pulling back Y type luer connector, seal wire
Chamber 14 and drug injection chamber 13 are withdrawn in casing 6.
