Description

A Y-type dual-purpose double-cavity and two-bag drainage device

technical field

The utility model relates to a Y-type dual-purpose, double-chamber, and two-bag drainage device, which belongs to the technical field of medical instruments.

Background technique

Intracranial aneurysm rupture and bleeding is one of the common emergencies in neurosurgery. On the basis of completing the etiological treatment, vasospasm and hydrocephalus are the two most important factors affecting the prognosis of patients, and about 12-20% of patients have Cerebral vasospasm, chronic shunt-dependent hydrocephalus occurs in about 10-20% of patients (according to existing studies, the location of aneurysm rupture and blood volume are the main factors affecting both), and further shunt surgery is required. How to clear the subarachnoid space or (and) the blood in the ventricular system early, safely, minimally invasively, and effectively, and how to apply anti-vasospasm drugs through multiple channels are the key links in the prevention and treatment of both.

At present, for the problem of vasospasm, there are mainly the following administration methods: (1) Conventional drug treatment: Due to the existence of the blood-brain barrier, it is difficult to achieve a high blood drug concentration in the brain, and it has side effects on the whole system, and At this stage, there is no clear and effective anti-vasospasm drug used in clinical practice; (2) Endovascular interventional therapy: anti-vasospasm drugs can be applied through intravascular intervention. The operation is complicated and has certain risks, and the treatment cost is high and difficult to treat. Multiple treatments; (3) intraoperative drug therapy: during craniotomy, anti-vasospasm drug application and flushing are used to treat vasospasm. To achieve long-term, stable blood concentration. For the problem of hydrocephalus, there are mainly the following solutions: (1) Lumbar cistern drainage treatment: Lumbar cistern drainage has replaced multiple lumbar punctures, avoiding the shortcomings of multiple and repeated lumbar punctures, but there are still intracranial infections , drainage tube blockage and other deficiencies; patients need to stay in bed during treatment, which has the disadvantages of increased pain and limited body position, and some patients cannot perform lumbar cistern drainage due to coma, lumbar diseases and other conditions; (2) hydrocephalus shunt surgery : For chronic shunt-dependent hydrocephalus that cannot be avoided by lumbar puncture and lumbar cistern drainage, another craniotomy is used to puncture the ventricle, and hydrocephalus-peritoneal shunt or hydrocephalus-atrial shunt is performed.

Among the related patents and literature on vasospasm and hydrocephalus after intracranial aneurysm hemorrhage, Min Yuanqing published a patent on "A Y-shaped double-chamber drainage device for surgical drainage" in February 2002, which is used to realize Flushing, drainage and drug injection are integrated, it is not an intracranial application device, and cannot be left in the body for a long time; Bu Xingyao issued the patent of "Continuous Cerebrospinal Fluid Drainage and Replacement Tube" in October 2008, and invented the integration of drug injection and cerebrospinal fluid drainage in the ventricle The replacement tube cannot achieve the function of local drug delivery in the parent artery. Tang Jiuning discussed the application of lumbar cistern drainage to reduce the incidence of hydrocephalus (chronic shunt dependence), and the application of ventricle-peritoneal shunt and other shunts Treatment of hydrocephalus. In the article "Neurosurgery Expert Consensus on the Prevention and Treatment of Cerebral Vasospasm), the application of anti-vascular drug sticking and flushing to treat vasospasm, intravascular application of anti-vasospasm drugs, and intravenous anti-vasospasm drugs were discussed respectively. However, these treatments The means still cannot completely and effectively control the occurrence and aggravation of cerebral vasospasm and hydrocephalus.

To sum up, there are still many deficiencies in the prevention and treatment of the two at this stage. In the Chinese literature and patents published in China, there is no application of "Y-type dual-purpose double-chamber two-bag drainage device" to treat vasospasm, Reports of hydrocephalus.

Our purpose is to pioneer the use of "Y-type dual-purpose dual-chamber and two-bag drainage device", which combines blood removal from the subarachnoid space and intraventricular system with local blood vessel application of anti-vasospasm drugs to improve the therapeutic effect of cerebral vasospasm. Reduce the incidence of hydrocephalus.
