Embodiment 1

[0044] see figure 1 , the present embodiment provides a simulation system 10 of a heart bleeding and hemostasis model based on augmented reality, including: a heart bleeding part model 101 manufactured by a three-dimensional model forming device, a depth camera 102 and an augmented reality device 103; the three-dimensional forming device can for example is a 3D printer;

[0045] The heart bleeding part model 101 includes one or more models of bleeding parts of the heart, for performing cardiac hemostasis simulation operations;

[0046] The bleeding site can be determined based on the collected medical images or based on experience. For example, if it is bleeding after cardiac surgery, it can be judged based on experience that the sites that are prone to bleeding after surgery include various incision sutures and puncture needle holes. The heart bleeding site model can be produced based on medical image data, such as images obtained by nuclear magnetic resonance equipment and / ...

Abstract

The invention provides a cardiac hemorrhage and hemostasis model simulation system and method based on augmented reality, and belongs to the technical field of medical analog simulation. The system comprises: a cardiac hemorrhage site model manufactured by using a three-dimensional model forming device, the cardiac hemorrhage site model comprising a model of one or more hemorrhage sites of the heart and used for performing cardiac hemostasis simulation operation; a depth camera, which is used for collecting a depth image of the cardiac hemorrhage part model in real time and is arranged in a preset area near eyes of a cardiac hemostasis simulation operator; and an augmented reality device, which is used for displaying at least part of images of other parts except the bleeding part in the heart according to the first position and / or the first angle, the first position and / or the first angle are / is determined according to the depth image, and the heart part displayed by the augmented reality device is associated with the heart part in the depth image. Entity-based hemostasis simulation operation can be realized, the simulation effect is good, and the manufacturing cost and the manufacturing time of the three-dimensional model can be reduced.

Description

technical field [0001] The invention relates to the field of medical simulation, in particular to a simulation system and method for a heart bleeding and hemostasis model based on augmented reality. Background technique [0002] In the field of medicine, simulation can achieve the role of teaching and training, and can also realize preoperative simulation, reduce operation time, reduce error rate, and improve operation success rate. At present, the more common method is to make a three-dimensional model to realize the simulation, and to realize the simulation through virtual reality. However, in the virtual reality simulation, because the actual model cannot be touched, the simulation effect on the operation is not good. Although the simulation method of making a three-dimensional model solves the problem of the operation simulation effect, the cost of materials and other materials is high, and the required The time is also longer. Especially in the preoperative simulation...
