Abstract

The invention belongs to the technical field of surgical medical training equipment, and relates to a manufacturing method of a personalized extracorporeal interlayer physical model.The method comprises the following steps of: manufacturing a three-dimensional geometric model based on a medical image, and carrying out smoothing treatment; manufacturing a bottom coating on the three-dimensional geometric model; forming a tearing opening in the bottom layer coating; carrying out surface modification or additional layer coating on a cut tearing-opening-shaped silica gel sheet, and attaching the silica gel sheet to a tearing opening; and manufacturing an outer coating on the bottom coating of the three-dimensional geometric model. According to the modeling method, the technical problem that a developable false lumen model cannot be manufactured in traditional cavity model manufacturing is solved; and meanwhile, a controllable false lumen triggering position and a controllable false lumen development path can be realized; and the aortic dissection model can be well manufactured according to the real size, and the clinical application value of the model is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of surgical medical training equipment, and relates to a method for making a personalized physical model of in vitro dissection, and more specifically, to a multi-layered transparent tube lumen based on a real size that contains developmental characteristics close to aortic dissection How to make a body model. Background technique [0002] Aortic dissection is a serious cardiovascular disease with an incidence rate of about 4 / 100,000 or higher. Large blood vessels such as the aorta generally have a layered structure, which can be simplified as being composed of three layers of intima, media and adventitia. Aortic dissection is manifested by unexplained damage to blood vessels, so that the blood that originally flowed in the lumen appears in the media layer of the blood vessel, and a new blood flow path is formed in the media layer. Due to the combined effect of various inflammatory mediators, the blood flo...
