Abstract
The utility model relates to a left/right coronary angiogram pipe special for the transradial artery. The left/right coronary angiogram pipe comprises an inclined catheter body, a horizontal catheter body and a vertical catheter body, wherein a lateral hole is arranged at the top of the inclined catheter body, the bottom end of the inclined catheter pipe is connected with the horizontal catheter body through a second elbow, an included angle between the inclined catheter body and the horizontal catheter body is 90 degrees to 120 degrees, the horizontal catheter body and the vertical catheter body are connected through a first elbow, and the included angle between the horizontal catheter body and the vertical catheter body is 90 degrees. The elbows are in round corner transition and can easily keep coaxial with a left/right coronary artery port to improve angiogram effects. Catheters are good in coaxiality and hardly enter small branches of conus branches above a right coronary artery opening or at the close end of the right coronary artery so as to be high in safety.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly relates to the special-purpose left and right coronary angiography pipe of a kind of trans-radial.
Background technology
Coronarography is a kind of effective ways of diagnosis of coronary heart disease.Conduit is inserted through thigh femoral artery or other peripheral arterial, deliver to ascending aorta, then seek a left side or ostium of right coronary artery and insert, inject contrast agent, coronary artery is developed.Coronarography is " goldstandard " that checks coronary heart disease, coronarography is often selected femoral artery, yet this vascular complication is relatively many, such as hemorrhage, large hematoma, false aneurysm, A-V fistula etc., need surgical operation and blood transfusion more during processing, increase like this complexity of operation and patient's misery.
Select the Transradial Approach coronary angiography can avoid this type of deficiency.Because the radial artery table is shallow, tiny, neighbouring without important nerve and blood vessel, so that trans-radial method coronarography has the characteristics such as continuous use that hemostasis is convenient, vascular complication is few, postoperative needn't be liied in bed, do not affect anticoagulant or thrombolytic drug, become in recent years important approach in the coronarography.Adopted first Experience of Transradial to carry out coronarography in 1989 by Campeau abroad, still just begin in recent years to prevail and adopt at home the radial artery percutaneous puncture to carry out the tubulose angiography.Because the easy spasm of radial artery and obturation, advocate that simple coronary angiography selects the 5F angiography tube, common type angiography tube especially, to reduce because the operating time to stimulation and the operation of blood vessel wall that the replacing conduit brings.
But because 5F shares the own characteristic of conduit, in use bring certain problem, when carrying out the right coronary artery radiography according to a conventional method, compare with Judkins R type conduit, the distance of the public tip of 5F end to the first bending is slightly long, and conduit is after rotating into RCS, its tip is easy to point to upper right and the position is higher, so select easily the super circular cone of selecting to enter the right coronary artery open proximal to prop up or enter to be opened on separately near the right coronary artery opening top circular cone of (being opened on separately RCS) branch such as to prop up.And when the blood vessel of conduit insertion is meticulous or excessively dark, decline of pressure or incarceration occur easily, under this state, if exert oneself injection of contrast medium, can cause ventricular fibrillation, coronary artery dissection or little vessel branch to break.
Therefore the clinical common type conduit of using other instead in recent years: TIG conduit (Terumo Corporation more, Japan), MITSUDO-K40 conduit (Hanako Corporation, Japan), BRACHIAL conduit (Medtronic, Inc.) etc.Yet all exist in some aspects its necessarily deficiency with upper conduit.TIG Unlversal catheter tip to the first deflection distance is slightly long than other type common type conduit, although in operation to turn round control property good, case to root of ascending aorta broadening, coronary ostium unusual (as higher or partially rear) is applicable, but during row right coronary artery radiography, because its most advanced and sophisticated easily sensing upper right side and position are higher, easily the super circular cone of selecting to enter the right coronary artery open proximal props up or is opened on separately near the ostium of right coronary artery top circular cone and the branch such as props up, the adverse consequences thereby quiver etc. in the chamber of causing.The smooth degree on the surface of BRACHIAL conduit is slightly poor, and the frictional resistance during the operation conduit is slightly large, walks to occur in line height bending or the operating process to use the type conduit to advance difficulty in the angiospastic situation at some blood vessel.
The utility model content
The technical problems to be solved in the utility model provides the special-purpose left and right coronary angiography conduit of a kind of trans-radial.This conduit is easier to insert ostium of right coronary artery, and alignment is good, can not cause the pressure incarceration, and is safe.
The problem that exists in order to solve prior art, the technical solution adopted in the utility model is:
The special-purpose left and right coronary angiography pipe of trans-radial, include inclined conduit body, horizontal duct body and vertical conduit body, the top of inclined conduit body is provided with side opening, the bottom of inclined conduit body connects by the second bending and horizontal duct bulk phase, angle between inclined conduit body and the horizontal duct body is the 90-120 degree, by the first crooked linking to each other, the angle between horizontal duct body and the vertical conduit body is 90 to spend between horizontal duct body and the vertical conduit body.
The length of described horizontal duct body is the 20-30 millimeter.
The length of described inclined conduit body is the 5-15 millimeter.
The radius of described the first bending is the 13-18 millimeter.
The radius of described the second bending is the 4-6 millimeter.
Advantage and effect that this utility model has are:
The special-purpose left and right coronary angiography pipe of this utility model trans-radial is owing to include inclined conduit body, horizontal duct body and vertical conduit body, the top of inclined conduit body is provided with side opening, the bottom of inclined conduit body connects by the second bending and horizontal duct bulk phase, angle between inclined conduit body and the horizontal duct body is the 90-120 degree, between horizontal duct body and the vertical conduit body by the first crooked linking to each other, angle between horizontal duct body and the vertical conduit body is 90 degree, thereby this structure is easy to keep the coaxial radiography effect of improving with left and right sides coronary ostium; Conduit is easier to insert ostium of right coronary artery, and alignment is good, seldom enters the circular cone that is positioned at right coronary artery opening top or right coronary artery near-end and the tiny branch such as props up, thereby avoid therefore causing the pressure incarceration, and is safe.Because the length of inclined conduit body is the 5-15 millimeter, in operation to turn round control property good, and its front end shape has good plasticity, so adaptability is good, particularly applicable to cases such as coronary ostium are unusual as higher or on the low side.
