Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of bolt stopper of getting.
Background technology
Apoplexy is commonly called as cerebrovascular accident, apoplexy, is a kind of cerebral blood circulation obstacle disease of unexpected onset, also is the severe complications of cerebrovascular disease.It comprises cerebral thrombosis, cerebral hemorrhage etc., has high " four height " characteristics of sickness rate height, disability rate height, mortality rate height and relapse rate.Arteriosclerosis be its main diseases because of, cerebral hemorrhage and cerebral thrombosis are final result.Cause that the modal vascular lesion of apoplexy is cerebral atherosclerosis and dural arteriovenous fistula, wherein:
Described cerebral atherosclerosis is the important cause of disease of apoplexy.Mainly occur in the big medium-sized artery of supply brain, tube wall is thickened, tube chamber narrows down, and intimal thickening, speckle form, under the hemodynamics effect speckle can break, ulcer, hemorrhage, thrombosis, cause arterial occlusion and blood supply district cerebral infarction thereof.At present, for the inaccessible polyphyly plaque rupture of cerebrovascular malformation cause thrombosis or speckle content come off cause, due to illness the feelings progress is fast, patient's poor prognosis, the discharging of the acute obturation of entocranial artery for free window or treatment window mainly contains intravenous injection thrombolytic drug thrombolytic, the tremulous pulse thrombolytic, machinery broken bolt or get four kinds on bolt, intracranial vessel thromboembolism thrombolytic weak effect due to big thrombosis of preceding two kinds of Drug therapy modes or the speckle content, Chang Buneng in time opens occluding vascular, at present, the comparatively ideal bolt mode of getting is that machinery is got bolt, and the existing bolt mode of getting then is not easy to take out of less speckle external, it is not thorough to cause getting bolt, as shown in Figure 1.
By retrieval, CN201939433U discloses a kind of utility model patent of intracranial thrombosis catching device, it comprises filter screen, described filter screen is olivary network structure, described olivary network structure is formed by the memory alloy wire braiding of many S shapes, fixedly connected with anchor portion respectively in the two ends of the memory alloy wire of described S shape, the opening direction of the serpentine of the memory alloy wire of two adjacent S shapes of the memory alloy wire of described many S shapes is opposite, the structure of having formed the figure of eight in twos, its advantage is: arrest the primary thrombus in the entocranial artery and the speckle content that comes off of interception proximal part vascular lesion by the characteristic of filter screen and memory alloy wire itself, its deficiency is to make complexity, and be unfavorable for getting bigger thrombosis, can only be used for arresting the less speckle of blood, the scope of application is limited.
(duralarteriovenousfistulas DAVFs) is unusual traffic between sinus durac matris such as cavernous sinus, lateral sinus, sagittal sinus and near arteriovenous thereof to described dural arteriovenous fistula, is outer feeding artery of intracranial and dlural sinus communication, is more common in the adult.Dural arteriovenous fistula is to occur in dural arteriovenous shunt, and its feeding artery is internal carotid artery, external carotid artery or vertebrarterial meningeal branch, and blood shunt is gone into venous sinus.Owing to flowing directly into venous sinus, arterial blood cause venous sinus inner blood tremulous pulseization and venous sinus internal pressure to increase, thereby make cerebral veins, venae cerebri backflow obstacle even adverse current, pathological changes such as cerebral edema, intracranial hypertension, brain dysbolismus, angiorrhexis be hemorrhage occur.At present, adopt intra-arterial thromboembolism interventional therapy usually for the Therapeutic Method of this dural arteriovenous fistula, along with the continuous development of intervention radiation endovascular treatment, vascular peg stay plug treatment DAVFs becomes main treatment means gradually.Concrete grammar is: adopt Seldinger technology femoral artery puncture intubate, the row aortocranial angiography is understood the feeding artery of fistula, the big or small position of fistula, the quantity and the direction of draining vein, then microtubular is put into feeding artery and thromboembolism it.This embolism materials utilizes turn to carry out thromboembolism usually, and its deficiency is: because the characteristic of turn itself makes turn can not form fixed shape, cause effect of embolization undesirable.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of novel structure, simple to operate, safe and reliable, get bolt quick, thoroughly, plugging effect is good, the scope of application is wide gets the bolt stopper.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of bolt stopper of getting, comprise delivery guidewire, the delivery guidewire front portion is arranged with the labelling guide ring, it is characterized in that the delivery guidewire front end is provided with spiral coil, spiral coil is made up of a spring and a memory alloy wire, memory alloy wire adopts Ultimum Ti silk material, memory alloy wire is through in the spring, memory alloy wire one end is fixedlyed connected with spring one end, the other end is fixedlyed connected with delivery guidewire, described spiral coil from least one circle of the clockwise vertical surrounding of space left surface back around to leading flank, back at least one circle of the counterclockwise vertical surrounding of leading flank around the plane that makes progress, in at least one circle of the clockwise horizontal circle in last plane back around side to the right,, around to lower plane, behind at least one circle of the clockwise horizontal circle of lower plane, be connected around to trailing flank in the counterclockwise vertical surrounding of right flank one circle back with seal wire in the microtubular at least one circle of the clockwise vertical surrounding of trailing flank back, make spiral coil under the shape memory of memory alloy wire, in blood vessel, form spatial sextuple shape.
This utility model is owing to adopt said structure, have novel structure, simple to operate, safe and reliable, get bolt quick, thoroughly, advantage such as plugging effect is good, the scope of application is wide.
