Abstract

A kind of three trough deformation diameter two dimension embolism spring ring of dual waves, it is characterized in that the Spring capable of diameter varying structure that it is wound by spring wire, the Spring capable of diameter varying is in small-big-small-big-small continuously distributed, the maximum value of two sections of enlarged diameter sections is equal, the minimum diameter of three sections of reduced diameter sections is equal, changes again to minimum diameter section in continuous camber line from minimum diameter section to maximum gauge section.The present invention 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

A kind of three trough deformation diameter two dimension embolism spring ring of dual waves
Technical field
The present invention relates to a kind of medical instrument, especially a kind of hemangioma embolization device, specifically a kind of dual waves Three trough deformation diameter two dimension embolism spring rings.
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.).Bullet on sale currently on the market Spring coil product category is various, such as GDC360 ° of spring ring product of Boston Scientific company, Cordis company 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 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.
Summary of the invention
The purpose of the present invention is be difficult to positioning for existing blood vessel embolism 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 good three trough deformation diameter of dual waves of effect Two-dimentional embolism spring ring.
The technical scheme is that
A kind of three trough deformation diameter two dimension embolism spring ring of dual waves, it is characterized in that the Spring capable of diameter varying that it is wound by spring wire Structure, the Spring capable of diameter varying is in small-big-small-big-small continuously distributed, and the maximum value of two sections of enlarged diameter sections is equal, three sections of reduced diameter sections Minimum diameter it is equal, from minimum diameter section to maximum gauge section again to minimum diameter section in continuous camber line change.
The spring wire is platinum, platinum alloy, Nitinol, stainless steel or other metals with good biocompatibility Material
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 is accurately positioned in vascular wall and endovascular high speed blood flow, and can block lacuna completely.2) by different line footpaths with And the combination of material can form standard shape, and have certain pliability and shape regain the strength of memory (in filling process, It needs to adjust position and direction, needs certain pliability, be separately straight line before transmission process, needed after Gu filling certain Shape-recovery capabilities).
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 can be very good to enter aneurysm, and can be very good to attach on vascular wall, mention The high success rate of operation is simultaneously conducive to patient's recovery, while decreasing dosage of the spring ring in an operation, alleviates The financial burden of patient.
Detailed description of the invention
Fig. 1 is one of structural schematic diagram of the invention.
Fig. 2 is second structural representation of the invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
Embodiment one.
As shown in Figure 1.
A kind of three trough deformation diameter two dimension embolism spring ring of dual waves, the Spring capable of diameter varying knot that it is wound by spring wire Structure, for the Spring capable of diameter varying in small-big-small-big-small continuously distributed, the maximum value of two sections of enlarged diameter sections is equal, three sections of reduced diameter sections Minimum diameter is equal, changes again to minimum diameter section in continuous camber line from minimum diameter section to maximum gauge section.Spring wire can be adopted With platinum, platinum alloy, alloy Nitinol, stainless steel or other metal materials with good biocompatibility, spring wire is twined It is wound on molding die and is heated and cured into shape shown in FIG. 1.
Embodiment two.
As shown in Figure 2.
The present embodiment is the difference from embodiment 1 is that the company that it is alternately connected to form by multiple wave crests and multiple troughs Continuous projection is similar to the structure of sinusoidal line, can be used in combination when specifically used or one section of progress of interception of making business as needed is clever It is living to use.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
