Virtual model three-dimensional mapping device and method

Abstract

The present invention provides a virtual model three-dimensional mapping device and method, comprising at least three application needle plates arranged on a base frame which can be gathered toward the center of the base frame, a plurality of slidable first needle posts on the application needle plate, and a bottom frame. There are at least three sliding mechanisms on the frame, and the application needle plate is connected with the bottom frame through the sliding mechanism; it also includes a CNC forming machine, which is used for forming the application needle plate; the key point coordinates of the virtual model are connected with the different ranks of the forming device. The depth position of the needle column is mapped one by one, and by analyzing and intelligently dividing the coordinate position of the key points of the virtual model, a plurality of application needle plates are respectively formed by the forming device, and then combined and spliced ​​into the required contour surface, realizing the Shape complex virtual 3D models into solid models.

Description

technical field [0001] The invention relates to the field of auxiliary medical devices, in particular to a virtual model three-dimensional mapping device and method for forming virtual models of aorta and other arterial blood vessels. Background technique [0002] At present, hospitals use CT technology to observe and study patients' conditions and provide solutions. However, the image data captured by CT is not very intuitive. The best way is to convert virtual images into physical models for doctors' reference. The existing technology usually adopts 3D printing converts the virtual model into a real model, but because the arterial structure is very complex, and some areas have a cross-mesh structure, it will consume a lot of time if the model is printed by 3D printing technology. A method of printing a model for in vitro fenestration of aortic stents. Therefore, there is an urgent need for a prototyping technology that can perform rapid prototyping of complex cross-mesh a...
