Abstract

The invention discloses a ventricle puncture guiding device, which belongs to the technical field of medical devices and can solve the problems of complicated, time-consuming, high cost, strong subjectivity, and high puncture difficulty in the prior ventricle puncture. The ventricle puncture guiding device includes: a first positioning structure; it includes a first positioning plate, the first positioning plate has a concave first arc edge; the first arc edge is used to fit the first line on the surface of the skull; The second positioning structure; it includes a second positioning plate and a plurality of third positioning plates; the plurality of third positioning plates are sequentially movably connected head to tail to form a fitting, and the second positioning plate and the plurality of third positioning plates are located on the same plane; The side edges in the length direction of the fitting are used to fit the second line on the surface of the skull; the first line and the second line are perpendicular or intersect; the second positioning plate includes a first side edge close to the first positioning plate, and the first side edge It is used to be in close contact with the surface of the first positioning plate to form an angle line. The invention is used for ventricle puncture.

Description

technical field [0001] The invention relates to a ventricle puncture guiding device, which belongs to the technical field of medical instruments. Background technique [0002] A ventriculocentesis is a medical procedure used to examine the brain. At present, there are two main methods of ventricle puncture: the first is CT (Computed Tomography, computerized tomography) or MRI (Magnetic Resonance Imaging, magnetic resonance imaging) guided stereotaxic puncture; although this method is accurate in positioning, it needs to be performed before surgery. For CT and MRI examinations, it is necessary to plan before the operation, and then import the plan into the computer and directional device. During the operation, the patient needs to be put on a head frame, and a relatively complex and large stereotaxic instrument is required for puncture; therefore, there are many steps in the operation, The time-consuming and applied directional device is expensive and bulky, and is not suita...
