Abstract
Bolt device is taken the present invention relates to a kind of support with thrombus capturing means, its technical scheme is：Support, which takes to be provided with protection pipe, protection pipe in bolt device, is provided with push silk, and the distal end for pushing silk is provided with thrombus capturing means.The thrombus capturing means are made up of the cylinder of mesh with leading end, and the mesh of the cylinder of mesh is L-shaped, and the junction of two twines is carried towards the warp architecture inside cylinder of mesh.It is an advantage of the invention that improving support takes the capture of bolt device and the ability of fixed thrombus, anti-tampon comes off blocking distal vessels during bolt is taken.Further, since the support takes bolt device to be formed by single metal pipe material through Laser cutting, in the absence of the overlapping of cylinder network structure, therefore with good compliance.
Description
Technical field
The present invention relates to medical instruments field, particularly to one kind can prevent blocking remote blood after thrombus breaks loose
The support with thrombus capturing means of pipe takes bolt device.
Background technology
Cerebral arterial thrombosis is a kind of disease triggered by brain blood supply arteriarctia or occlusion, brain tissue can be caused bad
Extremely, need to make revascularization within the shortest time after its generation.Clinically to the treatment side of cerebral arterial thrombosis caused by thrombus
Method mainly takes bolt including two kinds, i.e. medicine thrombolysis and machinery.Machinery takes bolt as a kind of new thrombus treatment method, especially fits
It is undesirable or be not suitable for the patient of thromboembolism treatment for thrombolytic effect.
Support takes bolt to be that a kind of machinery occurred recently takes bolt method, and this method is in the auxiliary of medical imaging technology
Help down, take bolt device to deliver at blood vessel embolism on support through conduit and make it discharge, support takes bolt device voluntarily to deploy, and relies on itself
Expansionary force it is chimeric with thrombus, then reclaim take bolt device, thrombus is taken out of.
Chinese invention patent CN103417257B discloses a kind of intracranial vascular thrombus removal equipment, and this takes the spiral shape of pin device
The distribution density of net ring element is different, and distal end distribution is closeer, and near-end distribution is then relatively sparse, can effectively prevent microthrombus from taking off
Fall.Chinese invention patent CN103997976A disclose it is a kind of take bolt cage with elongated axis and circumference, including common limit
The slender member of multiple open cells, this takes bolt cage effectively to remove embolism.Chinese invention patent CN105726088A is public
Open a kind of thrombus withdrawing device, include the support and core filaments of netted self-inflated, stent expansion state is cylindrical shape, near-end tool
Have an opening, distal end is closed, the thrombus withdrawing device can by thrombus it is uniform it is embedding be hung on the axial mesh of support, the thrombus fragment of generation leads to
Mount proximal end opening is crossed to enter inside it, and the remote collection being closed.United States Patent (USP) US2012/0245671A1 discloses one
Planting improves the intravascular stent of adherence quality, should include multiple row and the bridge muscle between adjacent column, support also includes and bindiny mechanism
Connected conical section.The support can be as taking bolt device to use, and when support deploys in thrombus, lap can be provided and caught
The ability with retaining thrombus is obtained, anti-tampon drops.Support disclosed in above-mentioned patent takes bolt device or takes pin device to be metal tube
Material laser engraving is formed, and the cross sectional shape of middle equal-diameter part still maintains the hollow structure of tubing, and the ability of fixed thrombus has
Limit.
Chinese invention patent CN103417261B discloses a kind of intracranial vascular thrombus removal equipment, and this takes pin device in tube chamber
A number of " hangnail " is provided with wall, thrombus can be fixed, thrombus breaks loose is prevented.Chinese invention patent CN10400635A
Disclose one kind to take bolt device and take pin device, it is on network structure provided with multiple indents with three-D profile for stretching into inner chamber
Bar, this, which takes bolt device and takes pin device to improve, catches bolt stability, prevents thrombus breaks loose.Chinese invention patent CN105662534A
Disclose and thorn is set respectively on a kind of taking thrombus device and its thrombus treating apparatus with bayonet fittings, the muscle of its unit grid
Shape structure, each bayonet fittings extend to intracavitary, by curved blood vessel or can reach the thinner blood vessel in distal end.Above-mentioned patent is public
The support opened takes bolt device or takes pin device and still formed for metal pipe material laser engraving, and is provided with some hangnails by structure design
Or projection, and tilted to lumen wall, to play a part of fixed thrombus, but the hangnail or projection of the offer of above-mentioned patent are
Along taking what bolt device axial direction was set, area of section is smaller, fixes the limited in one's ability of thrombus, above-mentioned hangnail or projection are taking in addition
Also there is the risk for scratching blood vessel in bolt device removal process.
United States Patent (USP) US2016/0113665A1 discloses a kind of grumeleuse for being used to remove blocking grumeleuse from blood vessel and collected
Device, the device includes inner side slender bodies and outside slender bodies, wherein inner side slender bodies has conveying form and the expansion of compression
Unfoldable shape, outside slender bodies can coat inner side slender bodies, and the device can prevent grumeleuse or clot fragments during bolt is taken
Dropped to distal end.But said apparatus is Multilayer metal tube engraving, nesting and is welded, rather than single metal pipe material laser carving
Quarter forms, and this can increase the external diameter taken under bolt device feed status, and reduction takes the compliance of bolt device.
As described above, current support is taken bolt device or takes pin device to be limited by structure, the chimeric position of itself and thrombus leads to
The outside of thrombus is often concentrated on, or the hangnail or projection of only small cross sections area are stretched into inside thrombus, inside thrombus
Contact area and the ability of fixed thrombus are extremely limited, and when pulling thrombus, support takes bolt device or takes pin device to act on blood
Power on bolt is uneven, and thrombus easily comes off from taking on bolt device, or producing thrombus fragment blocks distal vessels.In addition, by many
Although the support that layer metal tube is processed takes bolt device or takes pin device to be effectively increased the contact area with thrombus, simultaneously
Also the problem of increase of the external diameter under feed status is reduced with compliance is brought.
For the foregoing reasons, it is necessary to which a kind of improved support takes bolt device, it can efficiently be captured and fixed thrombus, thrombus
Fragment will not take bolt device to come off from support and block distal vessels, while having good compliance.
The content of the invention
It is an object of the invention to provide it is a kind of can prevent blocking remote blood vessel after thrombus breaks loose carry thrombus capture portion
The support of part takes bolt device.
To reach above-mentioned purpose, what the present invention was realized in：
A kind of support with thrombus capturing means takes bolt device, and the support takes bolt device to be provided with protection pipe, protection pipe and is provided with
Silk is pushed, the distal end for pushing silk is provided with thrombus capturing means.
The thrombus capturing means are made up of the cylinder of mesh with leading end, and the mesh of the cylinder of mesh is L-shaped, two nets
The junction of silk is carried towards the warp architecture inside cylinder of mesh.
The two ends of the thrombus capturing means are to set to be provided with developing mark simultaneously on leading end, near-end on taper, distal end
It is fixed together with pushing silk.Development wire coil or poly- containing developing material visual under X-ray is carried on the leading end
Compound sheath, the end of leading end is hemispherical.
