Embodiment

[0027] Taking the frontal plane as an example to describe the operation plane, the three auxiliary positioning planes connected to the frontal plane are the left temporal plane, the parietal plane and the right temporal plane. The fronto-parietal axis and the right temporal-parietal axis are the same as the front-to-back direction of the human body. The two up-and-down axes and the two front-to-back axes intersect on the left-right frontal-parietal axis to form the left and right front corners of the skull. In three-dimensional space, 5 Four faces and two corners connected by three axes form a complete structure, forming a three-dimensional structure with complete structure and stable space.

[0028] S1. Obtain the image data of the skull surface from the head CT, and use a 3D printer to print the three-dimensional spatial structure of the "4 sides, 5 axes, 2 corners" of the head into an integrated skull surface component;

[0029] S2. Completely reset the fitting of the crani...

Abstract

The invention discloses an individualized brain space stereo positioning technology, by introducing a face into the outer surface of the head, Concept of Axis and Angle, Repartition Name. The three-dimensional stereoscopic structure of four faces, five axes and two angles, which is composed of the operation face, three auxiliary locating faces, five axes and two angles, is acquired. Then the imagedata of the skull surface is obtained from the head CT, and the three-dimensional stereoscopic structure of four faces, five axes and two angles of the skull is printed into an integral skull surfacecomponent by using 3D printer. The three-dimensional stereoscopic structure of four faces, five axes and two angles of the skull is obtained. Complete reduction of the head surface component and theskull surface, so that the points on the operative surface and the points on the skull surface component completely coincide, assisting minimally invasive diagnosis, interventional treatment of braindiseases. The invention can realize multi-needle track, different angles and multi-point stereoscopic positioning of brain space from extracranial to intracranial brain pathological changes at the same time.

Description

technical field [0001] The invention relates to the field of brain space positioning, in particular to an individualized brain space stereotaxic positioning technology. Background technique [0002] The current clinical stereotaxic instrument for brain space can only complete single-needle positioning from extracranial to intracranial at a time, and is usually used for the diagnosis of intracranial tumors. There is still no instrument that can simultaneously perform multi-needle tracks, different angles, and multi-point auxiliary positioning on a certain intracranial space from the extracranial, and is used for clinically assisting the treatment of intracranial diseases. Contents of the invention [0003] In order to solve the above problems, the present invention provides a stereotaxic technology for individualized brain space, which is designed by utilizing the anatomical characteristics of the outer surface of the human skull and the CT data of the cranium, and can real...
