Embodiment Construction

[0028] Embodiments are described in detail below in conjunction with technologies and accompanying drawings.

[0029] The target area is extracted from medical images and preprocessed as shown in Figure 1 to make it convenient for spatial positioning and improve the bonding quality between layers of 3D printing ( figure 2 ), the thickness of the model becomes a hollow structure and the advantages of adding additional features for later clamping, and then slices the optimized model through software slicing software and applies 3D printing to print the model using PVC, a soluble material. Secondary hydration dissolution and surface cleaning. After the silica gel is prepared at a ratio of 10:1, it can be applied to the soluble model, such as image 3 , its technical characteristics include:

[0030] According to the estimated surface area of ​​the model, measure at least 3 times the basic dosage to configure the silicone glue, fix the model on the double-axis rotating device, ...

Abstract

The invention provides a method for making an individualized transparent silica gel model based on soluble materials. The individualized transparent silica gel model is a transparent silica gel modelbased on human organs. A soluble model cavity is made through model cleaning and a 3D printing technology oriented model repairing process based on medical images. The individualized silica gel modelof the invention improves the making process requiring multiple mold reversals in traditional cavity model making. An external model of a target organ can be made at the real size, and the clinical application value of the model is significantly improved. A transparent cardio-cerebral artery silicone tube made by silica gel blending can be used to conduct new medical-engineering applications withhigher practical application value in clinical training, medical education and many other aspects. Therefore, the invention provides a new set of transparent external model making scheme for blood vessels and other lumen tissues for clinic by combining medical image processing, human blood vessel model repairing, 3D printing, silica gel model baking and other interdisciplinary disciplines.

Description

technical field [0001] The invention belongs to the technical field of medical training equipment, and relates to a method for manufacturing a transparent hose cavity model based on a heart and brain blood vessel in a real size. Background technique [0002] Cerebral aneurysm is a serious cerebrovascular disease. Embolization surgery by using a catheter to penetrate the catheter from the large blood vessels of the human body to the location of the disease is a small trauma and quick recovery interventional method, but the surgical operation requires high technical requirements. Clinical experience Accumulation is difficult, and how to make doctors quickly accumulate relevant clinical experience becomes very necessary. Therefore, the present invention develops a carrier for the implementation of simulated training operations—a cerebral aneurysm embolism simulation training system based on CT images of real patients, so that beginners can Rapidly improve the technical level of...
