Human anatomic structure model and implant rapid forming method

Abstract

The present invention disclose a human anatomic structure model and implant rapid forming method. The method is characterized by comprising: firstly, obtaining three-dimensional digital models of an implant, an anatomic structure or parts and layers of the anatomic structure by software processing; secondly, performing inward or outward cavity, hollowing and thin wall processing on all or part of the models by the software to form an internal frame structure or add an internal tube cavity structure, thereby obtaining a printing model; thirdly, directly adding a supporting structure to a structure small in size and low in printing cost and performing printing; fourthly, performing 3D supporting structure analysis on a bulky, branch or netty structure, performing segmentation, printing the segmented model, and obtaining the model by assembling and bonding; and finally, further processing the model. According to the method provided by the present invention, the modeling precision can be improved, printing materials can be reduced, the costs and time are saved, and certain technological bottlenecks are avoided, so that the method is practical and easy to generalize.

Description

technical field [0001] The invention relates to the field of computer-aided modeling, in particular to the digital modeling of human body anatomy, implants and rapid prototyping methods. Background technique [0002] At present, the industrial revolution of 3D printing technology is in the ascendant, but the clinical application of this technology is still in the laboratory stage. There are three main reasons that restrict the clinical application of this technology: 1. Accuracy, clinical requirements for accuracy are high, such as tumor volume, location, etc. Information, if the deviation is large, it may lead to wrong tissue cutting during the operation. 2. The molding speed and clinical preoperative preparation time are limited, and the extension of one day will bring economic burden to the patient. However, 3D printing technology is currently time-consuming. In the new Before the technological breakthrough, this status quo will last for a long time. 3. Cost. At present, ...

[0002] At present, the industrial revolution of 3D printing technology is in the ascendant, but the clinical application of this technology is still in the laboratory stage. There are three main reasons that restrict the clinical application of this technology: 1. Accuracy, clinical requirements for accuracy are high, such as tumor volume, location, etc. Information, if the deviation is large, it may lead to wrong tissue cutting during the operation. 2. The molding speed and clinical preoperative preparation time are limited, and the extension of one day will bring economic burden to the patient. However, 3D printing technology is currently time-consuming. In the new Before technological breakthroughs, this status quo will last for a long time. 3. Cost. At present, the cost of 3D printed items is relatively high, and patients often cannot accept the high price, so there is no way to generate profits.

4. It is difficult to develop and promote bio-inks, and the cost is high

In addition, currently infected joint replacement revision temporary bone cement prosthesis is mostly handmade by doctors, and its shape is not accurate enough, which may cause some complications. 3D printing technology can be used to make up for such defects
