Abstract
The utility model provides a device for taking thrombus out of brain nerves and blood vessels. The device comprises a support and a push rod, which can move along the blood vessels, wherein the push rod is connected with the support for enabling the support to advance or retreat; the device further comprises a micro-catheter, the device can be pushed by the push rod to be arranged in the micro-catheter by penetration and can move along with the micro-catheter; and the support is of the shape of a hollow column which can expand and shrink automatically and arranged in the micro-catheter, the cylindrical surface of the support is like a hollow mesh, and the cylindrical surface at one end is arc-shaped. The device for taking the thrombus out of the brain nerves and the blood vessels, provided by the utility model, can effectively prolong the time of a treatment window, reduce the dosage of a thrombolytic medicament and the complications caused by thrombolysis and further achieve the effect of re-improving the blood circulation in the brain blood vessels.
Description
Technical field
This utility model relates to a kind of technical field of cardiovascular and cerebrovascular diseases device, relates in particular to a kind of cranial nerve vascular thrombosis withdrawing device.
Background technology
Along with the raising of China's living standards of the people, huge variation has taken place in life and dietary habit, the growth doubly of cardiovascular and cerebrovascular vessel case exponentially.Annual millions of people is above to be caused death or is disabled by cerebrovascular.Wherein the cerebral infarction patient increases case 200-300 ten thousand every year newly.Thromboembolism treatment is the Therapeutic Method that the most often uses at present, but the treatment window time of requirement must have an attack of one's old illness 4 hours in, and complication is often arranged.Interventional technique is that cerebral infarction therapy provides a kind of new selection again in recent years.Compare with the traditional intravenous thrombolytic, the intra-arterial thrombolytic of implementing by interventional technique has great advantage: treatment window time lengthening is to rising 8 hours after being ill, and the recanalization rate of vascular embolization can reach 90%, is higher than a medicament thrombolytic.And reduce the thrombolytic drug consumption, reduce the complication that causes because of thrombolytic.
The utility model content

A kind of cranial nerve vascular thrombosis withdrawing device that this utility model provides, the treatment window time that need to solve existing thromboembolism treatment is short, and with the problem of complication.
Technical scheme
In order to solve the problems of the technologies described above, this utility model provides a kind of cranial nerve vascular thrombosis withdrawing device, comprising:
Push rod, it is connected with support advances support or retreats;
Support, its hollow cylindrical for can independently expanding and shrinking is connected with push rod, and it is arranged in the above-mentioned microtubular.
Above-mentioned support is cylindrical, and the surface is a thread abortive haul shape, and one of which end cylindroid is an arcwall face.
The material of above-mentioned support is a Nitinol.
The cylindrical surface of above-mentioned support comprises a plurality of annulars that along the circumferential direction go up ordered arrangement.
The cylindrical surface of above-mentioned support comprises the sinusoidal wave shape of along the circumferential direction going up ordered arrangement.
The microtubular of above-mentioned a kind of cranial nerve vascular thrombosis withdrawing device and 0.010 to 0.021 inch is compatible, and the diameter of said a kind of cranial nerve vascular thrombosis withdrawing device is 1.5mm to 6mm, and length is 6 to 45mm.
Above-mentioned support is attached with and is used for the X line more than 5 and surveys localized gauge point.
Spacing is above 0.8 millimeter between the support ring of above-mentioned support.
Beneficial effect
A kind of effective extended treatment window time of cranial nerve vascular thrombosis withdrawing device that this utility model provides, the cerebral hemorrhage amount that reduces the thrombolytic drug amount and cause because of thrombolytic, thus reach the effect of improving the cerebrovascular blood circulation again.
Description of drawings
The support of a kind of cranial nerve vascular thrombosis of the embodiment of Fig. 1 this utility model withdrawing device.
The specific embodiment
Specify the specific embodiment of this utility model below in conjunction with accompanying drawing.
This utility model provides a kind of cranial nerve vascular thrombosis withdrawing device to comprise the seal wire that can move along blood vessel; Be enclosed within on the seal wire and and be arranged in its inside, the microtubular that moves along with above-mentioned seal wire by seal wire; Be enclosed within the microtubular and advance, the push rod that can advance or retreat; Be connected the hollow cylindrical support that can independently expand and shrink with push rod, and be arranged in the microtubular, advance or retreat by push rod control.
Utilize the process of a kind of nerve tract vascular thrombosis withdrawing device removal of thromboses that this utility model provides specific as follows.
At first seal wire is put into to passing location, thrombosis place along blood vessel; Secondly microtubular passes thrombosis along seal wire; Support is pushed by push rod then, in microtubular, gets into the thrombosis position, and withdraws microtubular, and autonomous expansion of support struts; Spur push rod at last and make the support recession, thrombosis is dragged away also taken out of human body in the suction catheter.
