Heart three-dimensional model constructing method and simulated heart surgery guidance system

Abstract

The invention provides a heart three-dimensional model constructing method and a simulated heart surgery guidance system, thereby settling technical problems of single heart surgery training mode, high cost, incapability of simulating a true surgery scene, incapability of realizing preoperative surgery simulation, few compatible heart models and relatively low training efficiency in prior art. A virtual reality simulated heart surgery guidance system comprises a virtual reality display device, a control input device, a memory and a central processor. The method and the system are advantageousin that a hearty dynamic model is displayed so that a doctor understands a heart motion process; immersive training of a true surgery scene is realized through VR technology, thereby optimizing a training effect; a doctor performs training by means of a VR handle and VR glasses, thereby realizing low training cost; a heart model is divided into multiple modules which are be independently edited, thereby facilitating construction of multiple pathological heart dynamic models and improving system compatibility; a wireless transmission module and a wired transmission module are arranged, therebyrealizing multiple-person viewing and improving training efficiency.

Description

technical field [0001] The invention relates to the field of surgical guidance, in particular to a method for constructing a three-dimensional heart model and a simulated cardiac surgery guidance system. Background technique [0002] The "China Cardiovascular Disease Report 2018" estimates that the number of patients with cardiovascular disease in China is 290 million, and some patients need surgery to correct heart deformities or lesions. However, cardiac surgery is highly risky and requires a high level of experience for surgeons. Therefore, doctors need extensive training before performing cardiac surgery. [0003] However, in the prior art, there are mainly two ways for doctors to learn cardiac surgery. One is to watch surgical videos and learn through video materials. In this learning method, real-time training cannot be performed after watching, and the learning efficiency is low, and the videos are past surgical videos with fewer types. The second is to train throu...

Problems solved by technology

In this learning method, real-time training cannot be performed after watching, and the learning efficiency is low, and the videos are past surgical videos, with fewer types

The second is to train through the simulated heart. In this learning method, there is no real surgical environment, and a large number of simulated hearts are required. The cost is high, and it is difficult to customize the production in a short period of time, and it is impossible to realize the surgical simulation before the patient's operation.
