Abstract
The utility model relates to a kind of intervention two-chamber spiral ducts, the first lumen, the second lumen totally two lumens are equipped in the conduit, the entrance of first lumen and the second lumen is in the inlet of conduit, the exit of first lumen is at the export end of conduit, the exit of second lumen is in the side of conduit, the outlet section of second lumen is in bowing, is increasingly towards the side of conduit.The utility model is increasingly towards the side of conduit by being provided with the second lumen that outlet section is in bowing in conduit.When the target blood for introducing conduit is more complicated, there are when bifurcated and larger bifurcation angle, seal wire can be drawn by the second lumen from conduit side exit, significantly reduced the difficulty for entering wide-angle bifurcated vessels, reduced operating time, reduce injury of blood vessel risk.
Description
Technical field
The utility model relates to a kind of intervention two-chamber spiral ducts.
Background technique
It often may require that in insertion type surgical operation therapy and conduit introduced to target blood, current way is all to utilize
Conduit and seal wire guide, but the vascular morphology of human body is ever-changing, especially the branch vessel of anatomy complexity, target blood
Blood vessel where with conduit at right angles or greater angle, often results in seal wire or conduit enters difficulty, extend operating time, can also
Blood vessel is damaged, additional pain is brought to patient.
Summary of the invention
The purpose of this utility model is that for overcome the deficiencies in the prior art and providing one kind can assist seal wire convenient
Into the wide-angle branch vessel of anatomy complexity, and use convenient intervention two-chamber spiral duct again.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of intervention two-chamber spiral duct,
It is characterized in that: being equipped with the first lumen, the second lumen totally two lumens in the conduit, first lumen and the second lumen enter
Mouth is in the inlet of conduit, and at the export end of conduit, the exit of second lumen is being led in the exit of the first lumen
The outlet section of the side of pipe, second lumen is in bowing, is increasingly towards the side of conduit.
Compared with prior art, the utility model is by being provided with outlet section in the second pipe of bowing in conduit
Chamber is increasingly towards the side of conduit.When the target blood for introducing conduit is fairly simple, such as there is no bifurcated or there are bifurcated but
When bifurcation angle is smaller, seal wire can reach target blood by the first lumen；When introduce conduit target blood it is more complicated,
There are when bifurcated and larger bifurcation angle, seal wire can be drawn by the second lumen from conduit side exit, significantly reduced and entered
The difficulty of wide-angle bifurcated vessels reduces operating time, reduces injury of blood vessel risk, is entering part unapproachable blood originally
Pipe branch creates condition, and close with existing conduit shape, meets operation doctor's use habit, and doctor uses more
Add smoothly.
As the further setting of the utility model, the outlet section of second lumen is bent in the shape of a spiral, end by
Gradually towards the side of conduit.Outlet section is bent setting in the shape of a spiral, can make the Curvature varying of the outlet section of the second lumen not
Can be too big, be conducive to that seal wire is smooth to be passed through.
As the further setting of the utility model, the outlet section of second lumen and first lumen and institute
Both corresponding parts of outlet section of the second lumen are stated in double-helix bending setting, the outlet section end of second lumen by
Gradually towards the side of conduit.Pass through going out the outlet section of second lumen and first lumen and second lumen
Both corresponding parts of mouthful section not only contribute to that seal wire is smooth to be passed through in double-helix bending setting, and are conducive to reduce and lead
The outer diameter of pipe.
The utility model is further described with reference to the accompanying drawing.
Detailed description of the invention
Attached drawing 1 is the utility model specific embodiment structural schematic diagram.
Specific embodiment
Specific embodiment of the utility model as shown in Figure 1, intervention with being equipped with the first lumen 1, the in two-chamber spiral duct
The entrance of two lumens 2 totally two lumens, first lumen 1 and the second lumen 2 is in the inlet of conduit, the first lumen 1
With the second lumen 2 close to the entrance of import can be it is parallel be arranged side by side, outlet, that is, first outlet 3 of the first lumen 1 is in
The export end of conduit, the outlet of second lumen 2 are the side that second outlet 4 is in conduit, the outlet of second lumen 2
Section is in bowing, is increasingly towards the side of conduit.Either by the way that the outlet section of second lumen 2 is curved in the shape of a spiral
Song makes end smoothly be gradually transitions the side towards conduit.
In order to enable the outer diameter of conduit will not increase outer diameter because inside is provided with two lumens as far as possible, described second
Both the outlet section of lumen 2 and first lumen 1 part corresponding with the outlet section of second lumen 2 are preferably in double spiral shells
Sigmoid setting is revolved, the outlet section end of second lumen 2 is increasingly towards the side of conduit.The outer diameter of such structural conductor
It will make the outer diameter of the mode conduit of spiral wound along linear first lumen 1 less than the outlet section of second lumen 2.
In addition, the front end (extension end of seal wire) of intervention two-chamber spiral duct can be straight, can also be to side
Deflection, to adapt to a variety of surgery situations.
The above is only preferred embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, or
The all design structures and thinking using the utility model of person do simple change or change, both fall within the guarantor of the utility model
Protect range.
Claims (3)
1. a kind of intervention two-chamber spiral duct, it is characterised in that: be equipped with the first lumen, the second lumen totally two in the conduit
The entrance of lumen, first lumen and the second lumen is in the inlet of conduit, and the exit of the first lumen is in conduit
End is exported, in the side of conduit, outlet section of second lumen close to outlet is curved in arcuation in the exit of second lumen
Song is increasingly towards the side of conduit.
2. intervention two-chamber spiral duct according to claim 1, it is characterised in that: the outlet section of second lumen is in
