Abstract

The invention discloses a manufacturing method of an individualized brain space 125I seed implantation auxiliary localizer, comprising the following steps: S1, obtaining head CT scanning data, determining an operation surface and three auxiliary localization surfaces on the brain CT image data; S2, determining the operation surface and three auxiliary localization surfaces on the head CT image data; S2, determining the coverage area of the positioner on the operation surface and the three auxiliary positioning surfaces; S3, spatial repositioning of the positioner; S4, designing the structure of each surface of the positioner; S5, using 3D printer, the designed brain tumor 125I seeds are implanted into the positioner to print the integrally formed skull surface component. The invention utilizes the individualized brain space stereotaxic positioning technology, CT image data, 3D printing technology and 125I seed TPS treatment planning system are used to make 3D printing brain tumor 125Iseed implantation localizer, which can assist the planed implantation of 125I seed into malignant intracranial brain tumor, minimally invasive diagnosis and interventional treatment of brain tumor.

Description

technical field [0001] The present invention relates to brain space 125 I particle implantation assisted positioning technology field, specifically related to a kind of individualized brain space 125 A method for making an auxiliary locator for implantation of I particles. 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 an individualized brain space 125 The production method of I particle implantation auxiliary lo...
