Problems solved by technology

However, compared with extraventricular shunt, the puncture point and direction of endoscopic third ventriculostomy need to be more precise, because advanced intraventricular surgery is required after puncture, so the puncture direction should not be grasped, because the operation time is prolonged or main reason for failure

Embodiment Construction

[0020] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0021] Such as figure 1 As shown, the present invention provides a lateral ventricle puncture positioning and guiding device, which is mainly composed of a headband 1, a connecting rod 2, a bracket 3, a guide plate 4, a guide tube 5, a protractor 1 6 and a protractor 2 7. The bracket 3 is supported above the headband 1 through the connecting rod 2 at its bottom. A guide groove 8 is respectively arranged on the side plates on both sides of the support 3, and the two guide grooves 8 are parallel. Respectively have a circular shaft one 9 at the two sides of the lower end of guide plate 4, circular shaft one 9 is inserted in the guide groove 8 that is positioned at its same side and can move horizontally therein. The circular shafts 9 on both sides are located on the same straight line, and the guide plate 4 swings back and forth ar...

Abstract

The invention relates to a lateral ventricle puncture location guiding device. The lateral ventricle puncture location guiding device is characterized by comprising a head band, wherein the head band is used for being arranged on the head in a sleeved mode, a guide plate which can horizontally move is arranged on a support, the guide plate is vertically arranged and can swing in a front-and-back mode, the swing angle of the guide plate is set through a first protractor, a guide tube which can horizontally move is arranged on the guide plate, the moving direction of the guide tube is perpendicular to the moving direction of the guide plate, the guide tube is vertically arranged and can swing in a left-and-right mode, and when the guide tube swings to be in place, the position of the guide tube is locked through a second locking mechanism, a through hole is formed in the guide tube, and a puncture needle can be guided to penetrate into the brain through the through hole. The lateral ventricle puncture location guiding device has the advantages of being simple in structure, convenient to use, capable of providing a location guiding device for lateral ventricle puncture and capable of being used for lateral ventricle puncture operations to guide cerebrospinal fluid out.

Description

technical field [0001] The invention relates to a positioning and guiding device for lateral ventricle puncture, which is used in lateral ventricle puncture operation to extract cerebrospinal fluid, and belongs to the technical field of medical devices. Background technique [0002] Hydrocephalus is a disease in which the volume of intracranial cerebrospinal fluid increases, the ventricular system expands or (and) the subarachnoid space expands due to excessive secretion of cerebrospinal fluid or (and) circulation and absorption disorders due to craniocerebral diseases. Its typical symptoms are headache, vomiting, blurred vision, papilledema, and even dizziness and seizures. Other symptoms include unsteady walking, mental decline, and incontinence. Neurological dysfunction in patients with hydrocephalus is related to the severity of hydrocephalus, the more hydrocephalus, the more severe the symptoms. [0003] Hydrocephalus can be caused by a variety of etiologies, commonly...
