AR (augmented reality) and VR (virtual reality) combined cornea smart operation training system

Abstract

The invention provides an (augmented reality) and VR (virtual reality) combined cornea smart operation training system. The system collects animal eyeball specimens during operation process and positive three-dimensional images of operation devices used by trainees in real time, performs the real-time side face 3D (three-dimension) scanning on the animal eyeball specimens, the operation devices used by trainees, and hand action of trainees through a TOF (time of flight) sensor, compares with preset data through a central processor and outputs guiding information and correction information, and sets up an augmented reality or virtual reality model containing the positive three-dimensional image, the guiding information and the correction information collected by a 3D microscope; through the AR glasses, the trainees can obtain the operation target object, status of the operation devices in use, the guiding information and correction information in real time, and thus the reality sense and on-site sense of cornea operation training are promoted, the real-time guidance in operation training is improved, the training operation of the cornea operation is shortened, the training cost of cornea is reduced, and the training quality is promoted.

Description

technical field [0001] The invention relates to the technical field of medical training, in particular to a corneal intelligent surgery training system combining AR and VR. Background technique [0002] According to the World Health Organization survey, corneal blindness is the second most common cause of blindness after cataracts. There are currently about 5 million corneal blind patients in China, and more than 100,000 new cases are added every year. Among these patients, most of them can regain their sight through corneal transplantation. However, due to various factors, the sources of corneas in eye banks across my country are extremely scarce, and many patients can only passively wait for donations. Statistics show that there are at least 500,000 patients waiting for corneal transplantation in my country every year, but less than 5,000 patients have the opportunity to receive corneal transplantation and regain sight. [0003] With the continuous development of science...

AI Technical Summary

Problems solved by technology

[0003] With the continuous development of science and technology, the emergence of artificial corneas solves the shortage of corneal donors and brings hope for vision recovery to 5 million and 60 million corneal blind patients in my country, but the serious shortage of corneal transplant doctors still lies in corneal blind patients. Huge obstacles on the way to the light

At present, there are about 28,000 ophthalmologists in the country, but less than 4,000 can perform intraocular surgery, and less than 100 doctors can independently complete corneal transplantation, and ophthalmologist resources are still lacking

[0005] The problem with virtual eye surgery training is that the equipment and procedures are complex and expensive, and the degree of simulation with real surgery is still far away, and the sense of reality is not strong
