Skull base surgery simulation teaching and training system

Abstract

The embodiment of the invention provides a skull base surgery simulation teaching and training system. The system comprises a tracking module and a fusion display module, wherein the tracking module is used for obtaining the position and posture of the tip end of a surgical tool in real time when the surgical tool performs operation on a printed target head model, obtaining a real-time image shotby a probe installed on the surgical tool and calculating a CT / MR three-dimensional rendering image of the position and posture of the tip end of the surgical tool displayed in a skull base tissue structure at a corresponding position in VR glasses; the fusion display module is used for performing real-time registration and fusion on the CT / MR three-dimensional rendering image determinately displayed in the skull base tissue structure at the corresponding position in the VR glasses calculated according to the position and posture of the tip end of the surgical tool and the real-time image shotby the probe installed on the surgical tool, so that the VR glasses display the three-dimensional image after real-time fusion. The skull base surgery simulation teaching and training system can achieve simulation teaching and training of a skull base surgery, and can effectively reduce the teaching difficulty.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a simulation teaching and training system for skull base surgery. Background technique [0002] At present, the traditional teaching and training methods of skull base surgery are based on the understanding of the narrow space under the direct vision of the endoscope, and the areas adjacent to the anatomical area are in the blind area, or only rely on static CT (Computed Tomography, computerized tomography) or MR imaging. (magnetic resonance, magnetic resonance) images to judge teaching. [0003] However, due to the deep anatomical part of the skull base region, there are important structures such as blood vessels and nerves in the region, the anatomical structure is complex, the space is small, and the operation is very difficult. The traditional teaching and training methods of skull base surgery are limited by multimedia equipment and cannot The intuitive display of ...

Problems solved by technology

[0003] However, due to the deep anatomical part of the skull base region, there are important structures such as blood vessels and nerves in the region, the anatomical structure is complex, the space is small, and the operation is very difficult. The traditional teaching and training methods of skull base surgery are limited by multimedia equipment and cannot Intuitive and vivid display of anatomical regions and their adjacent relationships increases the difficulty of learning, and it is difficult for trainees to form an intuitive, three-dimensional and comprehensive understanding of the skull base surgery space

Moreover, due to the limitations of laws, medical ethics, patient safety, difficulty in obtaining and reusing cadaver heads, and insufficient time for anatomy teaching, it is difficult for trainees to use patients or cadaver head specimens to perform practical operations. The opportunities and time for learning are limited, and it is difficult for trainees to quickly learn and master knowledge
