Virtual operation simulation training system for preoperative training and training method thereof

Abstract

The invention discloses a virtual operation simulation training system for preoperative training and a training method thereof. The system comprises a main node and multiple sub nodes in synchronous communication connection with the main node. Each of the main node and the sub nodes comprises a haptic interaction device, a soft tissue cutting simulation module and a realistic real-time rendering module. Through an operation process for a virtual operation trained on the main node recorded by the main haptic interaction device, the main soft tissue cutting simulation module and the main realistic real-time rendering module, the operation of a physician is mapped to each sub node in a real time mode, and the trained physician can sense the operation process via the sub haptic interaction device on the sub node. A model differential encoding algorithm is adopted, and each sub node can quickly obtain a three-dimensional operation model. A high-difficulty operation can be prevented from being trained on a patient, a learning curve and a training cost of the trained physician are shortened, and popularization and improvement of the soft tissue cutting operation technology are promoted.

Description

technical field [0001] The invention relates to a virtual surgery simulation training system for preoperative training and a training method thereof, belonging to the technical field of virtual reality in computer application technology. Background technique [0002] Most of the current soft tissue resections similar to tumors can only rely on the operator's experience and anatomical knowledge to judge the degree of tumor resection. Statistics show that about 20% of cases have postoperative residual lesions or complications such as hemiplegia and aphasia due to damage to normal nerve structures. At the same time, the training process for trainee doctors is also very long and costly. In the learning process, there are generally problems such as high risk, long growth cycle, and difficult implementation. Therefore, there is an urgent need for an effective virtual surgery simulation training system to avoid training difficult operations on patients, and at the same time shorte...
