Abstract
The invention discloses preforming seal wires in a kind of cerebral angiography, including conduit and seal wire, the seal wire includes metal inside, resin layer, functional coating and medication coat, there is the seal wire soft tip, connection tip axis rod interlude, proximal end to push rod segment, and the softness tip is helical-tip.Preforming seal wire can shorten distance and operating time of the past from femoral artery insertion conduit and seal wire in cerebral angiography of the present invention, especially make seal wire u-turn that can reduce the burden to patient's heart without heart, prevent the damage to valve, operation is completed in short time, the radiation that doctors and patients can be reduced is conducive to the early recovery of patient.
Description
Technical field
The invention belongs to the field of medical instrument technology, it is related to preforming seal wire in a kind of cerebral angiography.
Background technique
Cerebral angiography has been widely used in the brand-new x-ray of clinical one kind and checks new technology since being the nineties, it is first
An approach artery, generally selection right femoral artery are selected, an arterial sheath is placed by right femoral artery, is selected by the Arterial sheath different
Conduit selects into the artery of being shown under seal wire guidance, injects Iodine contrast medium.The blood vessel track that contrast agent is passed through is continuous
Piece is taken the photograph, is cerebrovascular digital subtraction angiography (DSA) by electronic computer aid imaging.
In recent years, as the development of shadowgraph technique and encephalic operation and some patients' lower limb vascular are poor, approach is difficult,
Conduit begins to transfer to from the right radial artery insertion full encephalography of progress and relevant encephalic operation, current seal wire and can be only inserted into
Aorta ascendens, due to the reasons in structure of arch of aorta position, conduit is not easily accessed descending aorta side, seal wire do not have yet into
Enter the function of descending aorta, the seal wire of this progress by heart reverses end for end mode, easily causes aortic valve and intravascular
The damage of wall, seal wire are unable to judge accurately with contact force when contacts blood, are easy to influence the normal bounce of patient's heart, be caused
The complication such as ventricle damage, interfere the electro physiology of heart, increase the molding difficulty of seal wire, bring pain to patient, for a long time
Radiography operation, certain radiation can be also brought to doctor and patient, if it is possible to without patient's heart directly from the arch of aorta
In descending aorta position, molding seal wire leads directly to brain artery, will shorten contrast time, reduce patient suffering and radiography
A big project present in art, changes conduit or guide wire is one of the approach for solving this problem.
Summary of the invention
It is an object of the invention to overcome defect existing for above-mentioned technology, a kind of brain easy to operate, degree of safety is high is provided
Preforming seal wire in angiography.It is inserted into conduit and seal wire from right radial artery, does not enter human heart turn u-turn, directly
From the arch of aorta turn round enter at descending aorta form seal wire, then towards brain blood vessel in, carry out radiography and its
His encephalic operation shortens operating time to reduce patient suffering, reduces doctors and patients' radiation.
Itself the specific technical proposal is:
Preforming seal wire in a kind of cerebral angiography, including conduit and seal wire, the seal wire include metal inside, resin
Layer, functional coating and medication coat, the seal wire have soft tip, connection tip axis rod interlude, proximal end push rod
Section, the softness tip is helical-tip.
Further, the material of the seal wire is Nitinol.
Further, the inside of the seal wire is equipped with fibre optical sensor, spring and fixing piece.
Further, the functional coating is hydrophilic coating, lubricant coating, label coating or bioactivity coatings.
Further, the medication coat is the medication coat of anti-inflammatory and resist blocking and that effect.
Further, the soft tip is w shape.
The utility model has the advantages that
Preforming seal wire can shorten distance of the past from femoral artery insertion conduit and seal wire in cerebral angiography of the present invention
And operating time, especially make seal wire u-turn that can reduce the burden to patient's heart without heart, prevents the damage to valve
Wound completes operation, can reduce the radiation of doctors and patients, be conducive to the early recovery of patient in the short time.
Detailed description of the invention
Fig. 1 is the schematic diagram of preforming seal wire in cerebral angiography of the present invention.
Specific embodiment
Technical solution of the present invention is described in more detail in the following with reference to the drawings and specific embodiments.
Referring to Fig.1, preforming seal wire in a kind of cerebral angiography, including conduit and seal wire, the seal wire include gold
Belong to inner core, resin layer, functional coating and medication coat, the seal wire has soft tip 1, connection tip axis rod interlude
2, proximal end pushes rod segment 3, and the softness tip 1 is helical-tip.
The material of the seal wire is Nitinol.
The inside of the seal wire is equipped with fibre optical sensor, spring and fixing piece.
The functional coating is hydrophilic coating, lubricant coating, label coating or bioactivity coatings.
The medication coat is the medication coat of anti-inflammatory and resist blocking and that effect.
The softness tip is w shape.
The foregoing is only a preferred embodiment of the present invention, the scope of protection of the present invention is not limited to this, it is any ripe
Know those skilled in the art within the technical scope of the present disclosure, the letter for the technical solution that can be become apparent to
Altered or equivalence replacement are fallen within the protection scope of the present invention.
