When in use, first guiding catheter 13 is inserted into intravascular, then intermediate conductor 12 is inserted into guiding catheter 13,
And then vessel catheter realizes extension in the blood vessels, and microtubular 11 is inserted into intermediate conductor 12 again later, realizes vessel catheter
Further extension in the blood vessels, and then the place of needs can be reached.
The present invention be used for aneurysm, the bleedings such as vascular malformation operation in when, the use process is as follows:
Intermediate conductor 12 after reaching corresponding blood vessel, passes through triple valve 3 with the help of thicker guiding catheter 13 or long sheath
Control, distal balloon catheter 9 is played using syringe, since the distal end of catheter body 6 is very soft, blood flow will push distal end ball
Capsule 9, and by catheter body 6 with vasotropic distal end.It, can to guarantee that blood flow is unimpeded after intermediate conductor 12 reaches target blood
The pressure of distal balloon catheter 9 is released.
Since intermediate conductor 12 is very soft, and with the help of distal balloon catheter 9 can by very tortuous blood vessel, reach from
The nearest position of lesion, so thinner microtubular 11 will be sent into desired blood vessel or artery tumor by intermediate conductor 12 to be become
Be very easy to.Simultaneously as intermediate conductor 12 is very soft, without any support force, but 3 selectivity of triple valve can be passed through
Play and 1 so that conduit is hardened by pressure to several stiffened sacculus 8, to obtain desired any support force.When in operation go out
It is now unexpected, such as aneurysm or angiorrhoxis bleeding, distal balloon catheter 9 at this moment can be played rapidly, and blocking blood flow reaches quick-acting haemostatic powder
Mesh.It is unobstructed by releasing sacculus recovery blood flow again after handling bleeding part well.
For the present invention when for taking in bolt operation, the use process is as follows:
Intermediate conductor 12 after reaching corresponding blood vessel, can pass through threeway with the help of thicker guiding catheter 13 or long sheath
The control of valve 3 is filled distal balloon catheter 9 using syringe, and since distal end of catheter is very soft, blood flow will push sacculus, and will
Catheter body 6 is with vasotropic distal end.It, can be by distal end ball to guarantee that blood flow is unimpeded after intermediate conductor 12 reaches target blood
Capsule 9 releases.
Since intermediate conductor 12 is very soft, and with the help of distal balloon catheter 9 can by very tortuous blood vessel, reach from
The nearest position of embolism, so taking bolt bracket microtubular 11 to cross at thromboembolism and will hold very much by intermediate conductor 12 thinner
Easily, at this moment bolt branch will be taken to be placed at thrombus by microtubular 11 to discharge, and plays distal balloon catheter 9.
Due to blocking blood flow, take bolt bracket during release and pulling plug, even if there is thrombus from the mesh for taking bolt bracket
Falling off to rush at blood vessel distal end by blood flow immediately, secondary embolism is caused, after taking bolt bracket to complete pulling plug, by distally leading
Pipe pumpback blood flow, can be external out by remaining thrombus pumpback, avoids secondary embolism.After completing pulling plug and pumpback, distal end ball is released
It is unobstructed to restore blood flow for capsule 9.
From the above, it is seen that the present invention has the advantage that
1, since the distal end of intermediate conductor 12 is very soft, and end has the distal balloon catheter 9 for one surpassing and complying with, when heaving distal end
When sacculus 9, blood flow can impact distal balloon catheter 9 to blood vessel distal end, and intermediate conductor 12 is helped to reach the blood vessel of more distal end, can be effective
Reduce operating difficulty.
2, can be by injecting salt water into stiffened sacculus 8, it, will not by the support force for any second connected pore channel 4 of pressurizeing
For the worry that is unable to hold out.
3, surgical procedure is safer: due to there is the presence of the super distal balloon catheter 9 complied with, even if aneurysm rupture in operation
Bleeding, without excessive worry.Sacculus is played when bleeding, can blocking blood flow immediately, reach hemostasis purpose.
4, operation is reduced, operation is simplified.
5, oval-shaped cavity 7 guarantee have two sets of catheter guide wires not make troubles because winding mutually in conduit.
6, since intermediate conductor 12 is very soft, therefore accomplish the minimal stimulation to blood vessel.
7, proximal end is thick, and distal end is thin and has braided steel wire guide-tube structure, so that override is more preferable.
Intermediate conductor 12 and vessel catheter provided by the invention, since the distal end of catheter body 6 is very soft, to intravascular
The stimulation of wall is smaller；And be provided with distal balloon catheter 9, when heaving distal balloon catheter 9, blood flow can by distal balloon catheter 9 to blood vessel distal end
Impact helps intermediate conductor 12 to reach the blood vessel of more distal end, it is difficult to can effectively reduce operation, and surgical procedure is more pacified
Entirely；Due to there is the presence of distal balloon catheter 9, even if aneurysm rupture bleeding in operation, without excessive worry, when bleeding, plays remote
Hold sacculus 9, can blocking blood flow immediately, reach hemostasis purpose；Intermediate conductor 12 and vessel catheter provided by the invention, operation letter
It is single convenient and efficient, surgical procedure can be simplified, so that operation is more quick and safe.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
