Method for producing human tissue simulated operation model and guide plate

Abstract

The invention discloses a method for producing a human tissue simulated operation model and a guide plate. The method for producing the human tissue simulated operation model an the guide plate comprises the following steps that CT / MR data about a human tissue are gathered, cleaning up and rebuilding are conducted, exact cutting of model space position data is conducted, based on a grinding model of an operation spot, operational information is added, an operation guide plate model is produced by reversed engineering, the obtained grinding model and operation guide plate model are converted to layer-by-layer cross-section data, and the layer-by-layer cross-section data are introduced to a 3D printer to conduct printing. According to the method for producing the human tissue simulated operation model an the guide plate, the accurate combination of a medical model and the guide plate is obtained by 3D printing, accurate simulated operation can be conducted with low cost and high speed, and a pre-operation simulation plan is executed accurately according to a pre-operation guide plate, so that operational risks are reduced, time on the operation is shortened, operational effect is improved, and great practical value is possessed.

Description

technical field [0001] The invention relates to the technical field of virtual surgery, and more specifically, to a more cost-effective and operable method for making a human tissue simulation surgery model and a guide plate. Background technique [0002] 3D printing technology or rapid prototyping technology is based on computer three-dimensional model data, melting or bonding materials, and building target objects layer by layer. 3D printing technology has been developed for nearly 20 years. In recent years, with the improvement of computer modeling technology and material quality, as well as the decline of printer and material prices, its cost has been greatly reduced, so the development has become more rapid. Especially in many fields such as industrial design, personalized production, rapid prototyping, etc., it has been more substantively applied. [0003] Among them, due to the diversity of the individual characteristics of the human body and the individual character...

Problems solved by technology

However, the current computer virtual surgery plan requires complex software program design, high-priced equipment investment, and professional technical personnel for management and maintenance, which greatly limits the application of virtual surgery in general hospitals.

In addition to the cost factor, the surgeon simulates the operation on the model. Because there is no reference standard or objective reference, the cutting site, direction, depth, and screw direction and depth cannot be accurately grasped during the operation. Certain surgical risks, technically still need to be perfected
