Embodiment 1

[0057] This embodiment relates to a method for printing a liver cancer tissue model using the method of the present invention, comprising the following steps:

[0058] 1) According to liver CT scan data and big data medical data (the data model is as follows Figure 5 and Figure 6 ), and print out the liver pipeline in segments (such as Figure 8 ), and smoothing the surface of the liver duct;

[0059] The segmentation method of the liver duct system is as follows: divide the liver duct system into inferior vena cava, left hepatic vein, middle hepatic vein, right hepatic vein, superior branch of the right posterior lobe, inferior branch of the right posterior lobe, superior branch of the right anterior lobe, The lower branch of the right anterior lobe of the liver, the upper branch of the left outer lobe of the liver, the lower branch of the left outer lobe of the liver and the integral caudate lobe branch and the left inner lobe branch of the liver are divided into eleven ...

Abstract

The invention relates to the field of medical model manufacturing, in particular to a method for printing a liver cancer model by a three-dimensional (3D) printing technology. The method for printing the liver cancer model by the 3D printing technology comprises the following steps: 1) printing a hepatic duct system model by a 3-D printer; and 2) according to the diagnosis, fixing a tumor tissue model at the corresponding position of the hepatic duct system model. By the method, a liver vessel system can be accurately printed; a soft model can be prepared by an industrialized remolding technology; the form of the tumor tissue can be flexibly simulated on the surface of the model; and the formed liver vessel system can be reused, so the use cost is reduced and the defects that the 3-D printing products are liable to break and are expensive are eliminated.

Description

technical field [0001] The invention relates to the field of medical model manufacturing, in particular to a method for preparing a liver cancer model. Background technique [0002] Primary liver cancer is one of the most common malignant liver cancers in the world. Most of the liver cancers occur in developing countries. my country is a high incidence area of ​​liver cancer, accounting for about 55% of the world. Its morbidity and mortality are on a steady upward trend. At present, the only effective treatment for liver cancer is surgical resection. However, for liver cancer resection, there is a certain degree of blindness in surgery, which causes excessive damage to the liver, so the risk of surgery is high. Postoperative complications are many, the recovery time is long, and the prognosis is poor. [0003] The liver is the largest organ in the human body and an important organ for metabolism. Modern people live under great pressure, and bad living habits directly lead ...
