Abstract
A kind of unicast paddy deformation diameter two dimension embolism spring ring, it is characterized in that the two dimension for the variable-diameter structure that it is wound by spring wire is enclosed, the both ends diameter of the two dimension circle of the variable-diameter structure is big and equal, and mid diameter is minimum, changes from maximum gauge to minimum diameter in continuous camber line.The utility model can be very good to enter aneurysm, and can be very good to attach on vascular wall, therefore is conducive to improve the success rate of operation and is conducive to patient's recovery, while decrease dosage of the spring in an operation, alleviate the financial burden of patient.
Description
Technical field
The utility model relates to a kind of medical instrument, especially a kind of hemangioma embolization device, specifically a kind of list
Trough deformation diameter two dimension embolism spring ring.
Background technique
Coil embolization technology has had more than 20 years development courses, spring ring bolt so far since the 90's of last century
Plug treatment is acknowledged as the goldstandard for the treatment of blood vessel knurl (such as aneurysm or arteriovenous fistula etc.).Currently on the market
Spring ring product category on sale is various, such as GDC360 ° of spring ring product of Boston Scientific company, Cordis
The TRUFILL DCS spring ring product of company, 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 basket
3D 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 spiral 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.
Utility model content
The purpose of this utility model is to be difficult to positioning and filling takes into account and influences to use for existing blood vessel embolism
The problem of effect, design it is both a kind of take into account, structure it is simple, easy to use, embolism forms the good unicast paddy deformation diameter two of effect
Tie up embolism spring ring.
The technical solution of the utility model is:
A kind of unicast paddy deformation diameter two dimension embolism spring ring, it is characterized in that the variable diameter knot that it is wound by spring wire
The both ends diameter of the two dimension circle of structure, the two dimension circle of the variable-diameter structure is big and equal, and mid diameter is minimum, from maximum gauge to minimum
Diameter changes in continuous camber line.
The spring wire is platinum, platinum alloy, Nitinol, stainless steel or other metals with good biocompatibility
Material
The utility model has the beneficial effects that
It 1),, can be with by the superposition of complicated structure or shape in conjunction with the common advantage of 2D and 3D by complicated shape
It is accurately positioned spring ring in vascular wall and endovascular high speed blood flow, and lacuna can be blocked completely.2) by not collinear
The combination of diameter and material can form standard shape, and there is certain pliability and shape to regain the strength of memory and (filled
Cheng Zhong needs to adjust position and direction, needs certain pliability, is separately straight line before transmission process, needs after caring for filling
Certain shape-recovery capabilities).
The utility model can treat bleeding, aneurysm and diversified vascular lesion, including malignant tumour, blood vessel are abnormal
Shape, arteriovenous fistula, pelvic congestion syndrome and varicocele.
The embolism spring ring of the utility model can be very good to enter aneurysm, and can be very good to attach in vascular wall
On, it improves the success rate of operation and is conducive to patient's recovery, while decreasing dosage of the spring ring in an operation, subtract
The light financial burden of patient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of unicast paddy deformation diameter two dimension embolism spring ring, it is a variable-diameter structure being wound by spring wire
Two dimension circle, the both ends diameter of the two dimension circle of the variable-diameter structure is big and equal, and mid diameter is minimum, from maximum gauge to minimum straight
Diameter changes in continuous camber line.Platinum, platinum alloy, Nitinol, stainless steel can be used for spring wire or other are compatible with good biological
The metal material of property, spring wire is wrapped on molding die and is heated and cured into shape shown in FIG. 1.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
Claims (2)
