Description
Technical field
The utility model relates to a kind of dual-purpose two capsule flow diverters of two-chamber of Y type, belong to the field of medical instrument technology.
Background technique
Haemorrhage caused by rupture of intracranial aneurysm is one of common acute disease of neurosurgery, on the basis of completing etiological treatment, blood
Pipe spasm, hydrocephalus are mostly important two factors after influencing patient more, and there are about 12-20% patients, and cerebrovascular convulsion occurs
Contraction, there are about the patients of 10-20%, and chronic shunting dependence hydrocephalus occurs (according to existing research shows that aneurysm rupture bleeding position
Set, blood volume is to influence the principal element of the two), need further shunt operation.How as early as possible, it is safe, minimally invasive, effectively
Removing cavum subarachnoidale or (and) blood of ventricular system, and using vasospasm drug be by all kinds of means to prevent and treat
The key link of the two.
Currently, being directed to vasopasm problem, it is mainly the following administration mode：(1) routine medication：Due to blood brain
Barrier exists, and causes encephalic to be difficult to reach higher blood concentration, and the side effect with whole body system, and just at this stage
For still without the medicinal application of clearly effective vasospasm in clinic；(2) intravascular Interventional Treatment：Intervention can be passed through
Intravascular application vasospasm drug, it is complicated for operation that there is certain risk, and medical expense is high, it is difficult to repeatedly treatment；
(3) medication is treated in art：It sticked in operation of opening cranium using vasospasm drug, rinse treatment vasopasm, this method is only
Be limited in art operation and do not have repeatedly, multiple dosing a possibility that, it is difficult to reach long-term, stable blood concentration.For brain
Ponding problem, mainly by following several solutions：(1) lumbar cistern drainage is treated：Lumbar cistern drainage has replaced multiple waist to wear,
The shortcomings that multiple, waist is worn repeatedly is avoided, but still has the deficiencies of intracranial infection, blocked drainage tube；Patient needs to lie in bed when treating, and has
Increase patient suffering, the disadvantage that position is limited, there are some patientss that cannot implement waist because of the limitation of the state of an illness such as comatose state, lumbar disease
Great Chi drainage；(2) hydrocephalus bypass：Waist is worn, lumbar cistern drainage is not avoided that the chronic shunting dependence brain of generation still
Ponding takes operation of opening cranium again, punctures the ventricles of the brain, carries out hydrocephalus-peritoneal shunt or hydrocephalus-atrium bypass.
After intracranial aneurysm bleeding in vasopasm, hydrocephalic related patents and document, Min Yuanqing was at 2 months 2002
Disclose about《A kind of Y shape double-cavity drainage device for surgical drainage》Patent, for realizing flushing, drainage and injection one
Body is not encephalic application apparatus, cannot permanent indwelling in internal；Star credit is walked to issue in October, 2008《Ventricle cerebrospinal fluid
Continuous drainage displacement pipe》Patent, the displacement pipe of example Note medicine of ventricles of the brain and drainage of cerebrospinal fluid one, can not achieve parent artery office
The function of portion's administration.Tang Jiuning exists《Intracranial aneurysm subarachnoid hemorrhage chronic hydrocephalus progress》In discuss and answer
The incidence that hydrocephalus (chronic shunting dependence) is reduced with lumbar cistern drainage, using the bypasses formula such as ventriculo-peritoneal shunt
Treat hydrocephalus.?《Cerebral angiospasm prevents and treats neurosurgery Consensus of experts)》It is anti-angiogenic that related application is discussed in one text respectively
Drug sticks, rinses treatment vasopasm, intervenes intravascular application vasospasm drug, intravenous applications vasospasm drug
Deng, but control cerebral angiospasm, hydrocephalic generation and the exacerbation that these treatment means still cannot be fully effective.
In conclusion but prevention both at this stage and treatment aspect there is also many deficiencies, during the country publishes
In document and patent, application " the dual-purpose two capsule flow diverter of two-chamber of Y type " treatment vasopasm, hydrocephalic report there are no.
Our purpose is the use " the dual-purpose two capsule flow diverter of two-chamber of Y type " started, will be in cavum subarachnoidale and the ventricles of the brain
Systemic blood removing is combined with local vascular application vasospasm drug, to improve cerebral angiospasm therapeutic effect, is reduced
Hydrocephalus incidence.
