Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to Unlversal catheter.
Background technology
Coronarography is coronary heart disease " goldstandard " inspection method, and coronarography often selects femoral artery.However
The approach vascular complication is relatively more, such as bleeding, big hemotoncus, false aneurysm, A-V fistula, needs when processing outer more
Section performs the operation and blood transfusion, increases the pain and hospitalization cost of patient in this way.Selection Transradial Approach avoids these deficiencies.
Radial artery is tiny compared with femoral artery (average man 0.28cm ± 0.04, female 0.26cm ± 0.05).Trans-radial method is coronal
Angiography is few, postoperative with stop blooding convenience, vascular complication need not to lie in bed, not influence anti-freezing or the continuous use of thrombolytic drug
The advantages that, it is an important approach in coronary angiography all the time.Foreign countries used Experience of Transradial in 1989 for the first time
Carry out coronarography.The domestic article for intervening diagnosis and treatment about radial artery in recent years is increasing, due to the easy spasm of radial artery, easily
Occlusion, to reduce spasm and occlusion, majority advocate that simple coronary angiography selects 5F angiography tubes, especially common type angiography tube,
To reduce the stimulation to vascular wall brought due to replacing conduit, while the operating time can be reduced.
But the own characteristic that 5F share pipes have it distinct, so also being brought in the facility for bringing operation certain
It is dangerous.There are 3 bendings in the conduit front, and this design makes it easier for upper limb Transradial Artery and carry out left and right coronary artery inserting
Pipe.Second bending has 4.0cm away from the first bending.Since 5F angiography catheters flexibility is good, there is a degree of plasticity, convenient for behaviour
Make, therefore 4.0cm conduits can substantially meet the radiography needs of most people.But arteria coronaria dextra is carried out according to a conventional method at it
When radiography, compared with JudkinsR type conduits, the distance of share pipe tip to the first bending is slightly long, and conduit is through rotating into the right side
After coronary sinus, tip is easy to be directed toward upper right and position is higher, therefore is easy the circle that super selection enters arteria coronaria dextra open proximal
Cone branch or enter single opening near arteria coronaria dextra overthe openings (single opening is in right coronary sinus) circular cone Zhi Deng branches.
Although 5F share pipe conduit diameters are thinner, and away from there is a side opening at conduit head end 3mm, the blood vessel diameter being inserted into is meticulous or mistake
It is deep, then it is easy to happen decline of pressure or incarceration, under this state, if firmly injection contrast agent, can lead to ventricular fibrillation, coronary artery
Interlayer or the rupture of thin vessels branch.In the past in conduit head end after repeatedly adjustment always easily into branch, and cannot allow right coronal dynamic
When arteries and veins development is good, 5F JudkiinsR type conduits are often used instead, method is identical as Femoral Approaches.Such as certain arteria coronaria dextra
Opening is high or anomalous origin case then selects 5F AmplatzL1 type angiography tubes.But the conduit causes the complication such as coronary artery tearing
Probability obviously increases, and increases the difficulty of operation.
Over the course for the treatment of, the head end of angiography catheter is inserted into coronary artery existing common type conduit, and hole is easy to be blocked
Inside coronary artery, causes blood that cannot flow into coronary artery from master pulse sinus, be unfavorable for treating.
Invention content
The technical problem to be solved in the present invention is to overcome blood to be in the prior art not easy to flow into the defect of coronary artery.
For this purpose, the technical solution used, the head end ecto-entad of Unlversal catheter, conduit are bent to form first successively

Side；In 30 to 50 degree angles, first bending part and second bending part between the elbow and first bending part
Between be in 90 degree angles, between second bending part and the third bending part be in 135 degree of angles, the third bending part with
It is in 135 degree of angles between in the middle part of the conduit.
In order to increase the blood circulation of angiography catheter and coronary artery, contrasting effects are improved, preferred technical solution is, side opening
Number is two.
In order to make angiography catheter manufacture upper more convenient, preferred technical solution is, two side opening faces settings,
Or dislocation is oppositely arranged up and down, or be arranged along the same side of the first bending part axial direction.
In order to keep the blood circulation of angiography catheter and coronary artery more smooth, preferred technical solution is that two side openings are
The radial direction setting at an acute angle of one bending part；
Wherein, two side openings are located on same circumference；
Or two side openings shift to install up and down.
Coronary artery requires supplementation with blood when due to treatment, in order to keep effect of the angiography catheter in treatment more preferable, preferred skill
Art scheme is that the number of side opening is three.
The connection of side opening and coronary artery when in order to ensure treatment, preferred technical solution is that three side openings are in the first bending part
Upper is in shift to install up and down；
Wherein, three side openings are oppositely arranged on the first bending part, wherein being a side opening on one side, another side is two sides
Hole；
Alternatively, three side openings are arranged in the radial direction of the first bending part in trisection；
Alternatively, being arranged along the same side of the first bending part axial direction.
The blood volume of coronary artery is flowed into when in order to ensure treatment by side opening, preferred technical solution is that three side openings are located at
On same circumference, on same circumference in three side openings, intermediate side opening is located at the arcuate midway point position of the side opening on both sides.
In order to keep the support force of angiography catheter in therapeutic process stronger, while it is empty in enough pipes to ensure that angiography catheter has
Between, more drugs can be accommodated, are conducive to treat, preferred technical solution is that catheter interior interts seal wire, the shape of seal wire
It is identical as the shape of conduit.
In order to ensure that the blood for flowing into coronary artery in therapeutic process by side opening is more smooth, by controlling blood flow direction, make
Blood enters that angiography catheter is more smooth, and preferred technical solution is that guide ring is connected on side opening, and guide ring is located at the interior of conduit
The head end in portion, guide ring towards conduit tilts.
In order to ensure that the blood for flowing into coronary artery in therapeutic process by side opening is more smooth, by controlling blood flow direction, make
Blood enters that angiography catheter is more smooth, while ensureing space in the pipe inside angiography catheter, do not influence the supply of drug with
And the activity of seal wire, further preferred technical solution are, along conduit axial direction projecting direction, section is arranged in guide ring, section
Radian is identical as pipe inner wall radian.
Technical solution of the present invention has the following advantages that：
Unlversal catheter provided by the invention is arranged elbow by the head end in conduit, a conduit is allow to do
Left and right coronarography and treatment reduce the trouble that angiography catheter reinserts, and reduce complication, are set in the first bending part
Side opening is set, side opening has certain distance with elbow, when elbow insertion coronary artery, makes side opening remain to be exposed at outside coronary artery, enables blood
Coronary artery is flowed by side opening, is conducive to treat.
