Tumor grid organ model 3D printing method

Abstract

The invention relates to a tumor grid organ model 3D printing method. The method particularly comprises the following steps: a cross section and a sagittal section when a human body is in a supine position are used for building crossed multiple grids on the surface of an organ, while the 3D grids are built, 3D modeling software specially adopted for original data for medical imaging (CT or MRI) picks out an organ or a tumor or a blood vessel in need of 3D printing, and building of 3D data is carried out. 3D data for the organ or the tumor or the blood vessel are built at the same time, and organ surface 3D grid data are built. The 3D data are inputted to a 3D printer for 3D model printing. According to the printed model of the invention, the tumor can be intuitively observed via a hollow organ shell and the distance between the tumor and the organ surface can be measured, a guide is provided for surgical resection, and a spatial distance between the tumor or the blood vessel inside the organ and an anatomical site on the organ surface can be directly read from the model.

Description

technical field [0001] The invention belongs to the medical field and relates to 3D printing, in particular to a method for 3D printing a grid organ model of a tumor. Background technique [0002] The current 3D printing models of tumors and / or blood vessels mainly use ABS (ABS resin), PLA (polylactic acid) and PVA (polyvinyl alcohol), elastic silica gel, photosensitive resin, and the like. The 3D printing model of ordinary tumors only prints the corresponding blood vessels and tumors, and the organs themselves are not printed. At the same time, only transparent silicone materials can be used for printing organs. The current printing cost is high, and tumors and organs cannot be directly measured through conventional 3D printing models. The distance between the surface and characteristic anatomical parts, and these data are helpful for clinical treatment such as surgery. If you want to print the organ itself and the blood vessels and tumors in the organ at the same time, yo...

Problems solved by technology

The 3D printing model of ordinary tumors only prints the corresponding blood vessels and tumors, and the organs themselves are not printed. At the same time, only transparent silicone materials can be used for printing organs. The current printing cost is high, and tumors and organs cannot be directly measured through conventional 3D printing models. The distance between the surface and characteristic anatomical parts, and these data are helpful for clinical treatment such as surgery

If you want to print the organ itself and the blood vessels and tumors in the organ at the same time, you can only print with transparent silica gel, which is expensive, and you cannot measure or accurately judge the spatial distance parameters of the tumor and blood vessels in the organ relative to the anatomical part of the organ surface through the model; conventional Using PLA and other materials (opaque materials) to print tumors and blood vessels inside the organ cannot print the organ itself at the same time, so through the 3D printing model, it is impossible to judge the spatial distance parameters of the tumor and blood vessels inside the organ relative to the anatomical part of the organ surface
