Problems solved by technology

[0003] However, the cast specimen technique mentioned above also has many limitations. First, a real human specimen is required to make a cast specimen. This technique requires a lot of specimens.
Secondly, due to the interlacing of various human body channels and the complex structure of these cast specimens, it is impossible to reproduce the specimens by using the mold-turning technology commonly used in industry, resulting in high manufacturing costs.
In addition, since each cast specimen is obtained from real human specimens, based on ethical considerations, these cast specimens cannot be used for commodity exchange and popularization of teaching in colleges and universities
The above limitations limit the wide spread and application of cast specimens

Embodiment 1

[0028] Embodiment 1: Introduce the process of making a lung cast specimen model based on the lung cast specimen.

[0029] 1. Perform CT scanning or three-dimensional laser scanning on the lung cast specimen to obtain the tomographic image data of the lung cast specimen.

[0030] 2. Import the continuous tomographic data of the lung cast specimens into the 3D reconstruction software Mimics, integrate the "threshold segmentation", "region growth" and other functional items that come with the 3D reconstruction software, perform image segmentation on the tomographic image data, and manually judge and adjust Two-dimensional images of structures such as pulmonary artery, pulmonary vein, trachea, and bronchi are extracted, and then three-dimensionally reconstructed to obtain three-dimensional computer models of various pipeline structures of lung cast specimens.

[0031] 3. Import the obtained computer 3D model of the lung cast specimen into the image processing software 3-Matic for ...

Embodiment 2

[0033] Embodiment 2: Introduce the process of making a cast specimen model of the calf with bone and artery structure based on the scanning data of the calf with bone and artery structure of the human specimen.

[0034] 1. Carry out CT scanning or three-dimensional laser scanning on the calf of the human specimen to obtain tomographic image data of the calf structure.

[0035] 2. Import the continuous tomographic image data of the calf structure into the 3D reconstruction software Mimics, use different thresholds to perform "threshold segmentation" on the bone and artery structure, and use functions such as two-dimensional image modification and region growth to realize the image of the tomographic image Segment and delete the skin, muscle, nerve tissue, etc. in the image, extract the two-dimensional image of the calf bone and arterial structure, and perform three-dimensional reconstruction on this to obtain the three-dimensional computer model of the calf cast specimen.

Abstract

The invention discloses a method for manufacturing an anthropotomy cast specimen model, which comprises the following steps of: a, acquiring initial image data of the existing cast specimen or the existing human body specimen; b, analyzing the initial image data, extracting structural data of various ducts in the human body from the initial image data, and performing corresponding image processing to form a three-dimensional model of the human body cast specimen; and c, importing the three-dimensional model of the human body cast specimen into quick forming equipment, and three-dimensionally printing the anthropotomy cast specimen model by using the quick forming equipment. A real human body specimen is not needed to manufacture the cast specimen model in the manufacturing method so as to solve the problem of ethics and the difficult problem of seeking manufacturing materials. The method can accurately and quickly manufacture cast specimen models of different human body parts, and greatly expands the wide spread of the human body cast specimen and the application of teaching experiments.

Description

technical field [0001] The invention relates to a method for making a medical model, in particular to a method for making a cast specimen model for anatomical analysis. Background technique [0002] Animals have a variety of different conduits in their bodies that perform different functions. For example, the arteries, veins, lymphatic vessels, digestive tracts, trachea, bronchi and other structures in the human body are interlaced and very complicated, and they must be properly handled in surgical operations. In order to better study the distribution range and traffic anastomosis of the pipeline branches in organs, people have developed anatomical cast specimen technology. Cast specimen technique is a specialized technique for making anatomical specimens, which has high application value in medical teaching and microsurgery. It uses various pipelines in the human body, such as blood vessels, bronchi, lymphatic vessels, hepatic ducts, pancreatic ducts, etc., as molds, and ...
