Background technology
Acute cerebrovascular disease is to lead to the one of the major reasons of human death, and in China, the death rate ranks first, higher than cancer
And angiocardiopathy, there is high incidence, high mortality, high relapse rate and high disability rate, cerebral angiography is diagnosis
It is that stenter to implant, Arterial thrombolysis, aneurysm embolism, machinery take the nerves such as bolt with prevention one of cerebrovascular disease most efficient method
The required inspection and evaluation of interventional treatment, cerebral angiography is still the goldstandard of cerebrovascular inspection and evaluation at present.
Cerebral angiography inspection is to be widely used in the novel Examined effect of cerebrovascular disease diagnosis and treatment, its behaviour the nineties in last century
It is as method：1) right common femoral artery is typically chosen as blood vessel approach from femoral artery, Arterial sheath is placed by femoral artery,
Along blood flow paths under seal wire guiding, pigtail catheter is put into arch of aorta initial part, has side close to pigtail catheter distal end
Seal wire is exited in hole, quick to project the contrast agent containing iodine then in the case where high pressure injector is injected, and blood vessel rail is passed through to contrast agent
Mark is continuously free of discontinuities to take the photograph piece, passes through area of computer aided imaging and obtains cerebrovascular form, also referred to as cerebrovascular digital subtraction angiography
(DSA), each branch vessel of the upper artery of bow is fully shown.2) pigtail catheter is exited together after being implanted into seal wire, similarly again
In the case where seal wire guides, replant into single curved angiography catheter (elbow is nearby without side opening), made to bending upper artery progress super-selective artery
Shadow can be very good to show cerebrovascular form and lesion situation by radiography, convenient for further carrying out neural interventional treatment,
Achieve the purpose that prevent acute cerebrovascular disease.As it can be seen that conventional method needs the conduit using two kinds of shapes that could complete radiography behaviour
Make.
The principal element for influencing radiography success rate and complication rate is subject's arteria arcuata developmental morphology and cooperation
Degree.The arch of aorta is divided into I type, II type and III type according to the starting site location of the upper artery of bow, and parting is higher, with aortic arch shape
Into angle it is smaller, implement superselective arteriography and be more difficult to, general I type patient accounts for the overwhelming majority, about more than 80%, and tradition is often
The bend pipe of rule can successful implementation completion radiography.The other types overwhelming majority can by special elbow such as " Simon ",
Conduits such as " Mani " successfully complete inspection, and that seldom sees can be completed by live plasticity conductor housing.The degree of cooperation of patient can
Reach requirement through appropriate calmness.
There is trans-radial to carry out contrast examination as approach blood vessel in recent years, it is possible to reduce the complication of subject occur and
Convenient for nursing, and special angiography catheter is developed, but the purpose of radiography is for further neural interventional treatment, because oar moves
Pulse-phase is tiny to femoral artery, and the conduit of interventional treatment is larger, it is difficult to which trans-radial implements neural interventional treatment, so as to limit this
The development of technology fails to be promoted.Therefore at present main cerebral angiography be still using femoral artery as approach artery based on.
Also there is the use of heart and brain composite conduit, but conductor housing needs seal wire to fix, seal wire influences injecting for contrast agent in conduit, influences
Contrasting effects, while conductor housing has the risk of abjection under the action of high pressure injector, is not also suitable for the cerebrovascular in practice and makes
The application of shadow.
As the development cerebrovascular disease of society has the tendency that occurred frequently year by year, and rejuvenation, while with living standard and matter
The raising of amount, the health care consciousness of people are also gradually increased, it is contemplated that life-time dilatation expectation is also higher, more and more to have cerebrovascular disease
The people of risk factor are ready to receive the inspection and evaluation cerebrovascular of cerebral angiography, to achieve the purpose that prevent cerebrovascular disease.Cause
This improves the safety of cerebral angiography inspection and success rate is particularly important.
The conduit of existing contrast examination has a defect that：It needs curved (see figure with pigtail catheter (see figure 1) and list
Shown in 2) two kinds of conduits could complete to operate, and when operation, needs advance and retreat conduit multiple with seal wire twice, extends operating time, increases
The incidence of operation risk and complication, while increase consumables cost so as to increase financial burden.
The defects of more than occuping, needs to be improved cerebral catheter, ensures outside success rate of operation, requires simultaneously
Reach the safety for improving operation, while can be cost-effective.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of simple in structure, easy to operate and safe and effective
L head dummy cerebral angiography Multifunctional catheters.
The utility model solves above-mentioned technical problem with following technical solution：
The utility model L head dummy cerebral angiography Multifunctional catheters, including catheter body, the distal end of catheter body is curved for nearly L-shaped
Several side openings are provided on the pipe shaft of head, nearly L-shaped elbow and close L-shaped elbow.
The side opening is twist arranged along the pipe shaft of catheter body.
The side opening is 6-7 around the quantity that pipe shaft is arranged one week.
The traditional two angiography catheter effects of the utility model conduit fusion, ensure the success rate checked, are combined into one simultaneously
Consumptive material and expense are reduced, while shortens the review time, reduces the generation of subject's complication, is worth clinical practice and popularization.
