Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of vascular repair conduit.
Background technology
The reasons such as the change of aging, dietary structure based on population, artery sclerosis and thrombotic diseases (including heart infarction,
Cerebral infarction, carotid artery occlusion, arteria carotis, the artery and veins such as aorta lumen vein disease) incidence increase year by year, disability rate and
Lethality is higher.
Currently, carrying out the treatment of thrombotic diseases frequently with following three kinds of modes：1, medical treatment uses anti-freezing, molten
The drugs such as bolt are treated；2, surgical intervention opens up notch on the blood vessel of thrombus deposition site, blood is taken out through the notch
Bolt；Minimally invasive interventional operation equipment is introduced thrombus deposition portion by 3, Minimally Interventional Therapy, i.e. percutaneous puncture by the miniature incision
Position, and carry out removing bolt.
The surgical instrument of Minimally Interventional Therapy includes mainly patch rotational atherectomy devices, patch cutting equipment, thrombus flushing absorption
Equipment, supersonic melting equipment, holder thrombectomy device, thrombolysis catheter equipment etc..But it states in device procedures in use, can cause to take off
Drift occurs for thrombus, the patch fallen, so as to cause distal embolization；And due to the limitation of operating time, the thrombus or patch that fall off
Absorption often not enough thoroughly, if extending the operating time, and will appear the case where losing normal blood or destroying excessive red blood cell.Shen
Please number be " 201010238525.0 ", Authorization Notice No. is " 102335022 B of CN ", entitled " partial sealing formula thrombus strikes off
The patent of invention of device " discloses a kind of partial sealing formula thrombus scaler for treating lower-limb deep veins thrombus, including：Pipe
Core, casing, the first sacculus, the second sacculus and bolt pompon is scraped, which has by expanding two sacculus simultaneously on vein
The position of thrombus deposition blocks to form one section of confined space, scrapes bolt pompon by rotation in the confined space and is broken to thrombus
It is broken and scrape it is de-.Described to scrape bolt pompon movable set outside core pipe and be arranged in the front of casing, it includes by remembering that this, which scrapes bolt pompon,
The sphere that B alloy wire is worked out is separately connected at the both ends end to end of sphere there are one positioning and guiding sleeve, two positioning and guiding sets
Cylinder is connected with core pipe cutting ferrule respectively, and core pipe, which can drive, scrapes the axial movement of bolt pompon work and radial rotating.The bolt pompon of scraping passes through
Core pipe is moved, but due to connecting first sacculus in core pipe, and when rotating core pipe, first sacculus is also transported therewith
It is dynamic, it may cause the thrombus, patch or neoplasm of diseased region that embolism displacement occurs.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide it is a kind of can be in the same of blocking lesion position blood flow
