Abstract

The invention discloses an immersive neurosurgical operation simulation method with real touch, belongs to the technical field of operation simulation, solves the problem that a human spinal operation cannot be truly simulated. The method comprises the following steps: S1, fusing an MRI image of myoloid tissues with a 3D virtual model of the spinal tissues to obtain 3D virtual models of the spinal tissues and the myoloid tissues, selecting and adding a lesion tissue virtual model in the 3D virtual models of the spinal tissues and the myoloid tissues, and importing data of all the virtual models into the wearable virtual imaging glasses; S2, measuring the elasticity modulus of lesion tissues, the spinal tissues and the myoloid tissues, and performing 3D printing to obtain a solid model consistent with the elasticity modulus of the lesion tissues, the spinal tissues and the myoloid tissues; and S3, through the combined action of the solid model, the wearable virtual imaging glasses and the surgical instrument, the spinal operation condition is simulated to the maximum extent, and a beginner is helped to quickly master the operation skill.

Description

technical field [0001] The invention belongs to the technical field of surgery simulation, in particular to an immersive neurosurgery simulation method with real touch. Background technique [0002] In the teaching of neurosurgery, the existing teaching is still to observe in the actual operation, and it is not practical to operate. For the teaching mode that cannot be combined with operation to learn, its efficiency is low and the learning cycle is long. With the development of science and technology, virtual reality technology is becoming more and more mature, and its imaging reality is getting higher and higher. With the help of sensing equipment, it can realize various scene simulations. Combined with neurosurgery surgery learning, students can combine virtual and real learning. Perform simulations before surgery to improve efficiency and accuracy during real surgery. [0003] The existing technology is to perform spine surgery on other animals to simulate the operation...
