Problems solved by technology

There are many deficiencies in this teaching method, for example: 1. Simulate the rubber figure for teaching. The material of the rubber figure itself is easy to age and needs to be replaced after being used many times. The price of the rubber figure is relatively high, and frequent replacement of teaching aids greatly increases the teaching cost.
2. The teaching of human anatomy in the laboratory by watching videos or autopsy teaching cannot play a role in making students learn anatomy very intuitively and easily, and generates a lot of training costs, such as textbook fees, autopsy fees, internships fee etc.
3. The form of expert operation observation prevents medical workers from fully immersing themselves in the actual scene, and understands and learns various surgical operations through multiple senses such as audio-visual and tactile. For young doctors, it is impossible to personally operate and operate with experts. Timely comparison and discovery of one's own mistakes and deficiencies will undoubtedly waste a lot of cost and time in training young medical staff and fail to obtain good training results
If inexperienced medical students or interns are allowed to perform the operation, the risk of the operation will be greatly increased, and the safety of the patient's life will not be guaranteed, which will increase the hospital's subsequent expenditure costs and negative social impact due to the failure of the operation.
5. Expensive animal experiments to be used in the teaching of animal vivisection
The cost is also relatively objective
6. To control the teaching quality of teachers and strengthen the assessment of trained students, it is impossible to use quantitative and scientific gold standards for quality management and control

Abstract

The invention provides a method for constructing a surgical virtual operation teaching and training system. The method comprises the following concrete steps: (1) acquiring various inspection data classified according to normal people and patients, intensively storing the acquired data, and constructing an integrated male virtual human model and an integrated female virtual human model; (2) carrying out geometric modeling, computational modeling and deformation computation on medical data, and carrying out modeling on bones and soft tissues by adopting a multi-outline three-dimensional reconstruction algorithm; (3) reconstructing by adopting a three-dimensional model of 3DMAX10, mapping and giving physiological characteristics to organic tissues; (4) compiling related objects and simulated scenes of a virtual operation by virtual reality modeling language (VRML); (5) carrying out preoperative preparation in the virtual operation scenes, and checking and confirming patient information;(6) carrying out complete operational details of the actual method of the virtual operation again; (7) establishing a simulated operation teaching evaluation system; and (8) carrying out comprehensive evaluation and examination on a teacher and each trainee. In the method, the simulated operation teaching system is constructed by utilizing the virtual reality technology, thereby providing a wide and transparent simulated teaching and research platform for hospitals and medical schools.
