Three-dimensional organ model and printing method, device and equipment of three-dimensional organ model

Abstract

The invention relates to the technical field of printing and particularly relates to a three-dimensional organ model and a printing method, device and equipment of the three-dimensional organ model. The printing method of the three-dimensional organ model comprises the steps that image data are obtained; three-dimensional modeling is carried out based on the image data to obtain a three-dimensional model, wherein the three-dimensional model comprises at least one of a tissue organ part, a blood vessel part and a lesion part; the tissue organ part and / or the blood vessel part are / is divided into a plurality of sections; different printing attributes are defined for the three-dimensional model to make at least one attribute mutation area exist between any adjacent sections; and printing is carried out to obtain the three-dimensional organ model. By means of the three-dimensional organ model, the printing method, device and equipment of the three-dimensional organ model, all the sectionscan be visually and accurately distinguished, an operation path can be better planned, operation risks can be better reduced, and the purpose of precise medical treatment can be achieved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a three-dimensional organ model, a printing method for the three-dimensional organ model, a printing device and printing equipment. Background technique [0002] With the development of science and technology, human beings have made a lot of progress in medicine, but in clinical medicine, there are still problems of low surgical success rate and high risk for some diseases. At present, 3D printing technology has significant applications in precision medicine. It can quickly create a 3D model that is completely consistent with the patient's organs based on the patient's medical imaging data, which is convenient for doctors to truly predict the intraoperative situation from multiple dimensions before surgery and plan surgery. The path and rehearsal of the operation greatly reduce the risk of the operation. At the same time, in medical teaching, students can also master the composi...

Problems solved by technology

[0003] As we all know, some organs of the human body are segmental organs, such as the liver can be divided into five lobes, eight segments or ten segments through arterial vessels, portal vein, hepatic vein and / or biliary system, and the lung can be divided into five lobes through arterial vessels and / or trachea Twenty segments, if you know which segment of the organ the tumor is in and the approximate location of the tumor before the operation, the doctor only needs to find and remove this segment during the operation, and the tumor will be removed accordingly. Or the doctor can directly find this segment and resect the tumor in this segment; for the doctor, it is much easier to find the segment of the organ than to find the tumor, but since the tumor is usually inside the organ, it is still difficult for the doctor to base on the Some 3D printed models can accurately determine which segment the tumor belongs to, and in the field of teaching, the existing organ models cannot intuitively and clearly distinguish the various segments of organs, which is not convenient for students to learn and master the segments of organs
