Description
Technical field
The invention discloses a kind of overlay films with zigzag bonded structure, belong to the field of medical instrument technology.It is public simultaneously
A kind of overlay film frame with zigzag bonded structure overlay film is opened.
Background technique
Common vascular diseases include the diseases such as aneurysm, angiorrhoxis, vascular puncture and hemadostewnosis.Aneurysm be by
In arterial blood tube wall because disease occurs, damage or congenital sexual factor make vascular wall thinning, under blood flow impact, weak blood vessel by
Circle is gradually protruded outward into, and then becomes aneurysm, it can vascular compression surrounding tissue organ.And aneurysm constantly grows and has
It may cause aneurysm angiorrhoxis, acute bleeding occur, cause life danger.
The advantages such as intravascular Interventional Treatment has small wound, few intercurrent disease, highly-safe, patient suffering is few, are increasingly becoming
Treat aneurysmal main method.Among these, overlay film frame method is a kind of common method.Overlay film frame method will be mainly in
The overlay film frame of compressive state is sent to vascular lesion position, after accurate positionin, is discharged, and the overlay film frame after expansion can cover
Lesion vessels completely cut off vascular lesion position and form new channel of blood flow, so that aneurysm be made to lose blood supply, reach treatment
Purpose.
Overlay film frame can not achieve by overlay film physical isolation aneurysm to aneurysmal active treatment, while overlay film
Non-degradable causes overlay film to be permanently present, line artery endothelialization, thus, there are thrombotic risk, it is small to need to carry out long-term anti-blood
Plate treatment.And overlay film has also blocked branch vessel when blocking the aneurysm of lesion vessels, and branch vessel internal organs is caused to lack
Blood is easy to induce patient's paraplegia or death etc..
The overlay film of the overlay film frame of the prior art is sewn into the surface or outer surface of bracket by sewing technology, or
Person is inner surface, or is covered on outer surface and inner surface simultaneously.
There is bonded structure overlay film at present, but bonding force is smaller, there is the risk of tearing in use.
Summary of the invention
An object of the present invention is to provide a kind of overlay film with zigzag bonded structure, and overlay film is covered bracket
When surface, overlay film improves the bonding of overlay film by using the bonding force for increasing bonded joint two sides with zigzag bonded structure
Intensity.
The second object of the present invention is to the overlay film for having zigzag bonding edge is covered on to the surface of the bracket of the prior art
(outer surface or inner surface) provides a kind of overlay film frame with zigzag bonded structure overlay film.
In order to achieve the above objectives one, the technical scheme of the present invention is realized as follows:
A kind of overlay film with zigzag bonded structure makes needed for cutting out certain thickness overlay film before overlay film frame
The length and width dimensions wanted, which is characterized in that cut out zigzag bonding edge in bonding site before bonding.
In order to achieve the above objectives two, the technical scheme of the present invention is realized as follows:
A kind of overlay film frame with zigzag bonded structure overlay film, which is characterized in that zigzag bonding edge will be had
Overlay film is covered on the surface (outer surface perhaps one of inner surface or outer surface and inner surface) of the metallic support of the prior art,
And zigzag bonding edge is bonded together to form cylinder and envelope metallic support.
Preferably, the zigzag is pointed structures or the zigzag is non-pointed structures.
Preferably, the quantity of the sawtooth is any amount in 2 to 1000.
Preferably, bonded adhesives at least is coated in a part of the top of the zigzag bonding edge and side.
Preferably, the bonded adhesives is the organic gel that can be degraded in human body.
The object of the invention is to what is be achieved.
One of the invention has the advantages that:
(1) overlay film provided by the invention with zigzag bonded structure, the zigzag bonded structure it is easy to process and
Carry out dimension control.
(2) overlay film provided by the invention with zigzag bonded structure, the zigzag bonded structure are easy to coat viscous
Connect glue.
(3) overlay film frame of the overlay film production using provided by the invention with zigzag bonded structure, improves overlay film
The tensile strength of bonded joint avoids bracket from cracking in the expansionary phase.
(4) overlay film frame of the overlay film production using provided by the invention with zigzag bonded structure, bonded joint
Intensity is greater than the intensity of overlay film base material.
(5) overlay film frame of the overlay film production using provided by the invention with zigzag bonded structure, because using
The bonded adhesives that can be degraded in human body, the bonded adhesives can degrade together with overlay film.
(6) overlay film frame of the overlay film production using provided by the invention with zigzag bonded structure, can control viscous
The degradation time for connecing glue reaches same or similar with the degradation cycle of overlay film base material.
