Embodiment Construction

[0035] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0036] The following embodiments take the human foot as an example for description.

[0037] Such as figure 1 , This embodiment implements the preparation of the human foot model through the following steps:

[0038] S1: Data acquisition and extraction:

[0039] Use medical imaging equipment CT to detect human foot, obtain foot surface, foot bone, blood vessel and nerve data, save the data, and extract and record the elastic modulus of foot bone, blood vessel and nerve surface;

[0040] S2: Data processing:

[0041] Use medical software to separately process the data of the foot surface, foot bones, blood vessels and nerves to make them into three-dimensional data (a format that can be recognized by a 3D printer);

[0042] S3: Model preparation:

[0043] Use the foot surface data to print the foot shell mold through the FDM 3D printing equipment. During the printing pro...

Abstract

The invention relates to preparation of functional models, in particular to a preparation method for a human body soft and hard tissue functional model. The preparation method solves the problem thatan existing functional model is free of personalized difference, high in cost and unreal in model surface hardness. The preparation method comprises the following steps that image data of human tissueis extracted; the image data is converted into three-dimensional data; 3D printing is used for preparing a tissue mold, and printed tissue models with different hardness are installed and fixed according to the spatial positions of real human tissue and organs; and liquid silica gel (close to the surface hardness and body color of the tissue) is poured into the mold containing hard and soft tissue models in different time periods according to assembly requirements, and the mold is removed after the silica gel is solidified. Through the method, the integrated soft and hard tissue functional model can be obtained, and the model has the body color of the human tissue and organs and the surface hardness close to the surface hardness of the different tissue and organs, and is suitable for simulating real operations and clinical training teaching.

Description

Technical field [0001] The invention relates to the preparation of functional models, in particular to a method for preparing the functional functional models of human soft and hard tissues. Background technique [0002] High-fidelity functional models play an important role in clinical treatment and medical education. Existing functional models are mainly realized through traditional casting and injection molding processes and 3D printing. Traditional casting and injection molding processes take a long time to prepare molds and are costly, and usually ignore the individualized differences between patients. Individualized differences can be achieved through 3D printing, but the medical models that are printed mainly made of hard or soft materials are far from real when used for human model anatomy. Summary of the invention [0003] In order to solve the problems of non-individualized difference, high cost and unreal surface hardness of the existing functional models, the present ...
