Improved external ventricular drainage device

Abstract

The invention belongs to the technical field of external ventricular drainage, and particularly provides an improved external ventricular drainage device. The improved external ventricular drainage device comprises a handle, wherein a limit block is fixedly connected with one end of the handle, a puncture needle is fixedly connected with one end of the limit block, a connecting block is clamped with the surface of the limit block, a clamp block is fixedly connected with one end of the connecting block, a joint is in sleeve joint with the surface of the connecting block, and a drainage needle is fixedly connected with one end of the joint. According to the improved external ventricular drainage device, the handle, the limit block, the puncture needle, the connecting block, the clamp block,the joint, the drainage needle, a groove, clamp grooves, a first round hole, a limit groove and a second round hole are arranged, by cooperation of the components in actual application, the force bearing area of the handle in a puncturing process is increased, so that the puncturing process is faster and more convenient, meanwhile, under the actions of the limit groove and a limit plate, the handle can rotate the joint and the drainage needle, therefore, the opening direction of the drainage needle is adjusted, and the drainage position is more accurate.

Description

technical field [0001] The invention belongs to the technical field of external ventricular drainage, and in particular relates to an improved external ventricular drainage device. Background technique [0002] Ventricular puncture and drainage, also known as cistern puncture and drainage, is a neurosurgery / general neurosurgery technique. Ventricular puncture and drainage is suitable for: patients with severe intracranial pressure caused by hydrocephalus, who are in critical condition or even occur In the case of brain herniation or coma, ventricle puncture and drainage are first used as emergency decompression rescue measures to create conditions for further examination and treatment. For patients with intraventricular hemorrhage, puncture and drainage of bloody cerebrospinal fluid can reduce ventricular response and prevent ventricular system obstruction. Most of the stress points of the external ventricular drainage devices in the prior art are small and circular, but the...

Ventricular puncture and drainage is suitable for: patients with severe intracranial pressure caused by hydrocephalus, who are in critical condition or even occur In the case of brain herniation or coma, ventricle puncture and drainage are first used as emergency decompression rescue measures to create conditions for further examination and treatment. For patients with intraventricular hemorrhage, puncture and drainage of bloody cerebrospinal fluid can reduce ventricular response and prevent ventricular system obstruction. Most of the force points of the external ventricular drainage devices in the prior art are small and round, but the force points of the device in this way are small, so it is not easy to puncture
