Abstract

The invention provides a surgical simulation method comprising the steps: acquiring a CT scanning image and performing three-dimensional reconstruction and rendering on the image according to an MC moving cube method so as to obtain a three-dimensional simulation model; when detecting the contact between the surgical instrument and the three-dimensional simulation model, the PBD particle positionin the contact process is continuously updated through the PBD position dynamics method to determine the deformed model; and real-time rendering is performed on the deformed model through the MC moving cube method. After the three-dimensional model corresponding to the scanning image is reconstructed by the MC moving cube method, the position of the PBD particles in the contact process is updatedby the PBD position dynamics method to determine the deformed model, and then real-time rendering is performed on the deformed model through the MC moving cube method to generate the touch deformationeffect of the three-dimensional simulation model in real time so as to effectively meet the training requirements of the surgery trainer for the complete video-assisted thoracoscopic lobectomy simulation scene.

Description

technical field [0001] The present application belongs to the field of artificial intelligence, and in particular relates to a surgical simulation method, device and system. Background technique [0002] The research on virtual surgery simulation technology was earlier. Since the world's first virtual surgery simulation system was developed in the early 1990s, it has rapidly developed into one of the most active research hotspots in virtual reality technology. However, in medicine, it is mainly used in orthopedics, stomatology, neurosurgery, etc., but less involved in thoracic surgery. In the lobectomy training simulation system, in addition to realizing the real physical modeling and simulation, the corresponding cutting and suturing operations must be performed on the model, so as to restore the operation process as realistically as possible to achieve a good training effect. [0003] At present, there is no surgical system on the market that realizes a complete set of lo...
