A lateral ventricle frontal horn puncture guiding device

Abstract

The invention provides a lateral ventricle frontal angle puncture guiding device. The lateral ventricle frontal angle puncture guiding device comprises a CT machine, a fixing support, a positioning device, an angle scale and a puncture catheter. The fixing support comprises a fixing rod, the axial direction of the fixing rod is the Y direction, and the direction perpendicular to the Y direction is the X direction. The angle scale is installed on the fixing support through the positioning device, and the angle scale can horizontally move in the X direction and the Y direction and can rotate in the X direction. The puncture catheter is installed on the angle scale, and the deviation angle of the puncture catheter can be adjusted along scale marks of the angle scale. By the adoption of the lateral ventricle frontal angle puncture guiding device, the accurate position of a puncture target point of a patient is extracted through the CT machine, the puncture position, the puncture angle and the puncture depth of the puncture catheter are determined by adjusting the deviation angels of the positioning device and the puncture catheter on the angle scale, the probability of improper puncture is decreased, and the safety level of an operation is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture guiding device for the frontal horn of the lateral ventricle. Background technique [0002] Puncture of the frontal horn of the lateral ventricle is a common operation in neurosurgery for ventriculoperitoneal shunt and external ventricular drainage. The position, angle, depth and other parameters of frontal angle puncture are the key to the success of ventriculoperitoneal shunt and external ventricular drainage. [0003] The ideal location for frontal horn puncture is in front of the foramen of Monro (the foramen of Monro) in the ipsilateral lateral ventricle, away from the intraventricular choroid plexus and the lateral ventricle wall. The commonly used method is freehand puncture, and the puncture point is 2cm inside the hairline and 2.5cm outside the midline of the skull. During the puncture operation, point the puncture needle to the opposite inner canthu...
