TRUFILL DCS spring ring product, the Hydro series spring ring product of Microvention company, ev3 company
Axium spring ring product etc..Although the spring ring of different company has different shape, such as soft 2D structure, at the 3D of basket
Structure, super soft filling 2D structure, etc., but final use principle is all consistent.
Ideal spring ring should have preferably at basket (positioning) performance, while have packing volume as much as possible again.
For the spring ring of identical material or the same shape, 2D structure has relatively good brill sky ability, more easily carries out empty
Between fill, but cannot fix well, be easy to cause displacement, it is serious to cause partial exfoliation to intravascular space；3D spherical shape shape
Space can be formed well, be supported in hemangioma as a gaily decorated basket, 3D shape covers open region well, and
And be not easy to shift, but the empty ability of brill is weaker, fills leakiness to tiny space, internal large-scale blank especially exists
It is not easy to block the flowing of blood in high blood flow.
Many companies are divided into different series, such as common 2D series, 3D series etc. according to spring loop-shaped again, because
For the two different characteristics thus during surgery general collocation use, but due to the defect of itself also cause it is high-leveled and difficult in operation
Degree and high risk also increase trouble also because of that an operation could be completed by usually needing 6-10 or so spring rings
The financial burden of person.So a kind of product for taking into account 2D and 3D advantage becomes new needs.
Summary of the invention
The purpose of the present invention is being difficult to for existing blood vessel embolism, brill is empty and filling takes into account and influences using effect
The problem of, design it is both a kind of take into account, structure it is simple, easy to use, embolism forms the more handles of the good more balls of effect and concatenates shape embolisms
Spring ring.
The technical scheme is that
A kind of more handles concatenation shape embolism spring rings of more balls, it is characterized in that the three-dimensional ball that it is at least wound by three by spring wire
Body 1 and two two-dimentional spring bodies 2 form, and one end of first two-dimentional spring body 2 is connected with first three-dimensional sphere one end, and first
The other end of root two dimension spring body is connected with one end of second three-dimensional sphere, one end of the second dimension spring body and second three-dimensional
The other end of sphere is connected, and the other end of second two-dimentional spring body is connected with one end of third three-dimensional sphere.
The other end of the third three-dimensional sphere is connected with third root two dimension spring body 2
The diameter of the spring wire of the formation three-dimensional sphere 1 is less than the diameter for forming the spring wire of two-dimentional spring body.
The spring wire is platinum, platinum alloy, Nitinol, stainless steel or other metals with good biocompatibility
Material product.
Beneficial effects of the present invention:
1) by complicated shape, bullet can be made by the superposition of complicated structure or shape in conjunction with the common advantage of 2D and 3D
Spring coil bores sky in hemangioma, finds space, and can block lacuna completely, makes angiomatous filling increase in density, anti-hemostasis
Tuberculation recurrence.2) standard shape can be formed by the combination of different line footpaths and material, and with certain pliability and
Shape, which regains the strength of memory, (in filling process, to be needed to adjust position and direction, certain pliability is needed, separately before transmission process
For straight line, certain shape-recovery capabilities are needed after caring for filling).
The present invention can treat bleeding, aneurysm and diversified vascular lesion, including malignant tumour, vascular malformation,
Arteriovenous fistula, pelvic congestion syndrome and varicocele.
Embolism spring ring of the invention, is formed by 2D and 3D spiral shape, practical particularly suitable as Raschig ring.Work as spring ring
When being disposed, the 2 empty abilities of dimension structures brill are good, and searching spacial ability is strong, and help is pushed to whole spring ring in hemangioma, reduces
Kick pipe (repercussion ejection microtubular).3 dimension structures can Cheng Lan, can be very good filling space, reduce excessive spring ring filling,
To reduce operation designing, mitigate sufferer burden.2D structure keeps multiple 3 dimension structures to connect each other, keep one it is stable
Filling, not because blood flow is excessive, and changes position.Therefore it also improves the success rate of operation and is conducive to patient's recovery, while
Reduce dosage of the spring ring in an operation, alleviates the financial burden of patient.
