Artificial human skeleton manufacturing method based on radiation detection

Abstract

The invention provides an artificial human skeleton manufacturing method based on radiation detection. The method comprises the following steps: obtaining the bone tissue, skeleton and outline dimension of a human body from a cadaver specimen so as to manufacture an entity model of the specimen or material equivalent to the specimen; manufacturing a three-dimensional virtual digital model of the human body according to a fresh cadaver; after mutual complementation and optimization of the entity model and the digital model, implementing 3D printing to obtain a physical entity model equivalent to the tissue, or manufacturing an entity physical model by using a reverse molding female die, wherein a bone material comprises thermoplastic or thermosetting resin and high-phosphorus high-calcium compound powder, and the high-phosphorus high-calcium compound powder is prepared by mixing apatite and calcium carbonate; bonding the manufactured bone tissue with mucilage equivalent to cartilage to form local parts; and movably or fixedly connecting the local parts to form an entire human body skeleton. According to the method, a high-phosphorus high-calcium radiation absorption characteristic can be met, and a heterogeneous structure and a mosaic structure of bone cortex, cancellous bone and red marrow are realized.

Description

technical field [0001] The invention belongs to the interdisciplinary field of science, engineering and medicine combining medicine, material science, manufacturing and control technology, relates to a method for manufacturing a simulated human skeleton, and in particular to a method for manufacturing a simulated human skeleton based on radiation detection. Background technique [0002] Bones have the functions of overall support, protection of organs and connection of phantom limbs. The weight of bones is 14.2% of the total weight of the body. The human skeleton model is a model that simulates the size of the human bone structure and is connected by joints. It is an intuitive teaching aid for basic anatomy teaching. Through the model, people can correctly understand the bone structure and conduct research on pathology and rehabilitation.

Problems solved by technology

[0003] However, there are some deficiencies in the preparation process of the traditional human skeleton model, which limits the practical application of the human skeleton model; specifically, the deficiencies are as follows:

[0004] 1. Traditional medical skeleton models are mostly made of gypsum plus urine-formaldehyde resin. Although the skeleton models prepared with this raw material have certain mechanical strength, they cannot meet the composition requirements of high phosphorus and high calcium content of radiation model materials. Therefore, it cannot meet the microscopic radiation absorption characteristics of high phosphorus and high calcium;

[0005] 2. The traditional skel
