Abstract
The utility model relates to medical instruments fields, disclose a kind of antegrade blood flow conduit, including tube body and fin, and two ends of the tube body are respectively equipped with connectivity port, are the first connectivity port and second connection end mouth.First connectivity port is equipped with hemispherical connector, is provided with through-hole at the top of the hemispherical connector.The end of the fin is connected around the tube body periphery, and close to first connectivity port.The fin is made of translucent elastic material, and extra two panels, and expansion is in umbrella.Antegrade blood flow conduit provided by the embodiment of the utility model can treat patient around aneurysm, reduce aneurysmal rupture in therapeutic process, greatly ensure that the life security of patient.
Description
Technical field
The utility model relates to medical instruments fields, more particularly to a kind of antegrade blood flow conduit.
Background technique
Aneurysm is the lesion and damage due to arterial wall, forms arterial wall limitation or dispersivity expansion or bulging.It is dynamic
Arteries and veins tumor is main performance with dilatancy, pulsation lump, can be occurred at any position of arterial system, and dynamic with limbs trunk
Arteries and veins, aorta and arteria carotis are relatively conventional.
Interventional therapy is the common treatment method of aneurysm, does not need a large amount of and long-term to take medicine after the method operation
Object, as long as and posterior traffic aneurysm is not particularly greatly that the effect with interventional therapy is typically all highly desirable.But
In interventional procedure, the remote outlet that used conduit or seal wire find blood vessel between aneurysm knurl at present is relatively stranded
It is difficult.Therefore it is very necessary for developing a kind of conduit of distal end that can actively find blood vessel.
Utility model content
It is difficult to find blood between aneurysm knurl the purpose of this utility model is to overcome conduit of the existing technology
The problem of pipe remote outlet, provides a kind of antegrade blood flow conduit, which can carry out relevant around aneurysm knurl
Treat work.
To achieve the goals above, the utility model provides a kind of antegrade blood flow conduit, including tube body and fin, the tube body
Two ends are respectively equipped with connectivity port, are the first connectivity port and second connection end mouth, and the fin is placed in described first and connects
This one end of port is connect, the fin is made of translucent elastic material, and the fin is more than two panels.
Preferably, the fin is connected around the tube body periphery.
Preferably, the fin expansion is in umbrella, so that blood flow and fin is had biggish contact surface, while also not stopping blood
In the flowing of blood vessel.
Preferably, first connectivity port is equipped with hemispherical connector, prevents from touching blood vessel or dynamic in the blood vessel
Arteries and veins tumor causes blood vessel and aneurysmal rupture.
Preferably, it is provided with through-hole at the top of the connector, facilitates administration over the course for the treatment of.
Through the above technical solutions, conduit can be made smoothly to bypass aneurysm knurl to trouble the drive of fin by blood flow
Person treats, and catheter proximal end is connected to hemispherical connector, it is possible to reduce aneurysmal rupture in therapeutic process, greatly
It ensure that the life security of patient, and this guide-tube structure is simple.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment.

Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
As shown in Figure 1, in one embodiment, providing a kind of antegrade blood flow conduit, including tube body 3 and fin 4, the tube body
3 two ends are respectively equipped with connectivity port, are the first connectivity port 2 and second connection end mouth 5.First connectivity port 2 is set
There is hemispherical connector 1, prevents from touching blood vessel or knurl causes blood vessel and knurl to rupture.It is provided at the top of the connector 1 logical
Hole 6 facilitates doctor will be in infusion of medicine human body.The end of the fin 4 is connected around the periphery of the tube body 3, and close to institute
State the first connectivity port 2.The fin 4 is made of elastic material, has good compliance, flexibility and bio-compatible
Property.The tube body 3 is also to be made of elastic material, and translucent, the fin more than 4 is presented with the tube body 3 in the fin 4
Remaining two panels, expansion are in umbrella.
Conduit described in the present embodiment, before entering blood vessel, fin 4 is closure and is fitted tightly over around tube body 3, side
Just conduit enters blood vessel；After entering blood vessel, due to the mobility of blood, fin 4 is started to spread out, and blood flow flowing pushes fin
4, so that conduit be pushed to move along the direction that blood flow flows, it is effectively shielded from aneurysm, searches out the remote outlet of blood vessel.
Antegrade blood flow conduit provided by the embodiment of the utility model can treat patient around aneurysm, and reduction is controlled
Aneurysmal rupture during treatment greatly ensure that the life security of patient, and this guide-tube structure is simple.
Preferred embodiments of the present invention are described in detail above, still, the utility model is not limited to this.At this
In the range of the technology design of utility model, a variety of simple variants can be carried out to the technical solution of the utility model, including each
Technical characteristic is combined with any other suitable method, these simple variants and combination equally should be considered as the utility model
Disclosure of that belongs to the protection scope of the utility model.
