Y-type dual-purpose drainage instrument with dual-chamber and dual-capsule

Abstract

The invention discloses a Y-type dual-purpose drainage instrument with two chambers and two capsules, which consists of a child and mother capsule structure and a Y type double-lumen tubes structure. The child and mother capsule structure includes a common external wall of the child and mother capsule, and an ascus inner wall and a mother cyst inner wall which are not communicated with each other, wherein the ascus inner wall and the mother cyst inner wall respectively form a ascus cyst cavity and a mother cyst cavity. The Y-type double-lumen tubes structure is provided with two branched ducts, which are respectively a first branched duct and a second branched duct respectively. One end of the first branched duct is provided with a plurality of side poles and the other end is communicated with the ascus cyst cavity through an intracavity pipeline and an ascus channel, while one end of the second branched duct is provided with an arc capsule structure with an opening on a medial cystic wall and the other end is communicated with the mother cyst cavity through an external cavity pipeline. By adopting the Y-type dual-purpose drainage instrument with two chambers and two capsules, anti-spasm medicine is regularly and sustainably applied in local vessels in a brain, thereby improving the intracranial drug concentration and effectively preventing and controlling the spasm of brain vessels. In addition, the lumbar cistern operation is replaced to avoid puncturing ventricle again in the hydrocephalus shunt operation, thereby reducing incidence of hydrocephalus.

Description

technical field [0001] The invention relates to a Y-type dual-purpose, double-chamber, and two-bag drainage device, which belongs to the technical field of medical devices. Background technique [0002] 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 ...

AI Technical Summary

Problems solved by technology

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 Methods still cannot fully and effectively control the occurrence and aggravation of cerebral vasospasm and hydrocephalus

[0005] 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
