Description

가상현실 기반의 교육용 백내장 수술 시뮬레이션 시스템Virtual reality based educational cataract surgery simulation system
본 발명은 가상현실 기반의 교육용 백내장 수술 시뮬레이션 시스템에 관한 것으로, 더욱 상세하게는 사용자의 머리에 착용된 디스플레이부로 가상 백내장 수술 화면이 출력되고, 환자정보가 입력된 백내장 수술 프로그램에 따라, 사용자가 출력된 가상 백내장 수술화면상에서 수술도구를 조작하여, 가상 수술을 수행할 수 있는 가상현실 기반의 교육용 백내장 수술 시뮬레이션 시스템에 관한 기술이다.The present invention relates to a virtual reality-based educational cataract surgery simulation system, and more specifically, a virtual cataract surgery screen is output to the display unit worn on the user's head, and according to a cataract surgery program in which patient information is input, the user outputs it. It is a technology about a virtual reality-based educational cataract surgery simulation system capable of performing virtual surgery by manipulating a surgical tool on a virtual cataract surgery screen.
2015년 Lancet 보고서에 따르면, 안전한 환경에서 수술 받지 못하는 세계인구가 15억명을 상회한다. 하지만, 전세계 외과의사의 3분의 2는 수술 교육을 제대로 받지 못하며, 현재의 도제식 의료 교육방식으로는 그 규모를 늘리기 어려운 현실에 놓여있다. 전문의를 양성하는 데 기본적으로 15,000~20,000시간이 소요되는데, 수련의 주당 근무시간이 유럽의 경우 48시간, 미국의 경우 80시간, 한국의 경우 80시간으로 법제화 되어 있어, 수련인들이 수술에 참여할 수 있는 기회가 적다.According to the 2015 Lancet report, the world population without surgery in a safe environment exceeds 1.5 billion people. However, two-thirds of surgeons around the world are poorly trained in surgery, and today's apprenticeship medical education is in a difficult situation to scale up. It basically takes 15,000 to 20,000 hours to train a specialist, and the working hours per week are legalized to be 48 hours in Europe, 80 hours in the United States, and 80 hours in Korea, so trainees can participate in surgery. Less chance
더불어 백내장은 가장 큰 실명요인으로서, 실명 인구의 48%가 백내장으로 인하여 실명하고, 백내장으로 인한 실명인구가 전세계적으로 1,800만명에 달한다. 노인성 질환인 백내장으로 인해, 70대 인구의 73%가 수술이 필요하고 80대 인구의 96%가 수술이 필요하다. In addition, cataract is the biggest blindness factor, with 48% of the blind population being blind due to cataracts, and the population of blindness due to cataracts reaches 18 million worldwide. Because of senile disease, cataracts, 73% of the 70s need surgery and 96% of the 80s need surgery.
일반적으로 의사의 수술훈련은 사전에 이론 교육을 한 이후 실제 시술에서 연습이 동시에 이루어지도록 되어 있다. 따라서 숙련되기까지는 수술 중에 실수가 발생할 위험이 높고, 사전에 겪어보지 못한 상황을 훈련 받지도 못한 상태에서 접하게 되는 경우도 빈번하므로 사고 발생의 위험성이 항상 존재하게 된다.In general, the surgeon's surgical training is practiced in real practice after theoretical training in advance. Therefore, there is a high risk of mistakes during the operation until skilled, and there is always a risk of accidents because there are frequent situations in which an unprecedented situation is encountered without training.
특히 최근에는 전통적인 절개술보다 회복 시간이나 통증을 획기적으로 줄일 수 있는 최소침습적 수술법들이 확산되고 있다. 최소침습적 수술은 수술 부위를 최소(ex, 10cm이하)로 절개한 이후, 절개 부위를 통하여 내시경과수술기구를 삽입하여 수술하는 방법이다. 그러나 이러한 방법은 수술 기구의 조작이 난해할 뿐만 아니라, 모니터를 통해 보여지는 영상에 원근감이 없고 현실감이 떨어져서 수안 능력의 저해를 가져온다. 또한, 길이가 긴기구들을 통해 수술 부위와 접촉하기 때문에 전통적인 절개술보다 미세한 촉감의 전달이 둔해진다. 더불어, 기구들이 절개 부위를 중심으로 회전하기 때문에 길이에 따른 지렛대 효과로 내부 움직임이 반대로 되어 직관적이지 못하며, 실제보다 동작이 증대된 상태로 수술 부위에 전달되므로 기구의 미세한 제어가 어렵고 손떨림이 증대된다. 따라서 최소침습수술 기술은 전통적인 절개술보다 습득하기가 어렵다.In particular, recently, minimally invasive surgical methods have been spreading that can significantly reduce recovery time or pain than traditional incision. Minimally invasive surgery is a method in which a surgical site is incised to a minimum (ex, less than 10 cm) and then an endoscopic surgical instrument is inserted through the incision site. However, this method is not only difficult to manipulate the surgical instruments, but the image seen through the monitor has no perspective and the sense of reality is reduced, leading to a decrease in the ability of the eye. In addition, the delivery of a fine tactile feel is slower than that of a traditional incision because it comes into contact with the surgical site through long instruments. In addition, because the instruments rotate around the incision, the internal movement is reversed due to the leverage effect along the length, and it is not intuitive. . Therefore, minimally invasive surgical techniques are more difficult to acquire than traditional incisions.
가상현실 기반의 수술 시뮬레이터 시스템에 대한 종래의 기술을 살펴보면, 현실감과 몰입감이 부족하다는 문제점을 갖고 있다. 가상수술 의료 시뮬레이션을 구성하는 다양한 요소 기술 중 현실감 있는 시각적 가시화 기술이 아직까지 수술 환경을 완벽하게 재현하지 못하고 있다. 특히 가상 수술 수행 시에, 가상화면 상에서 수술현장을 체험하는 것에 초점이 맞춰져 있고, 가상수술을 수행함에 있어, 수행자와 가상 수술 시뮬레이터 간의 정보교류가 부족한 현실이다.Looking at the conventional technology for the virtual reality-based surgical simulator system, it has a problem of lack of realism and immersion. Of the various element technologies that make up virtual surgical medical simulation, realistic visual visualization technology has not yet fully reproduced the surgical environment. In particular, when performing a virtual surgery, the focus is on experiencing a surgical field on a virtual screen, and in performing virtual surgery, there is a lack of information exchange between the operator and the virtual surgery simulator.
따라서, 전술한 문제점을 보완하기 위해 본 발명가들은 가상현실 기반의 백내장 수술 시뮬레이터 시스템의 개발이 시급하다 인식하여, 본 발명을 완성하였다.Therefore, in order to supplement the above-mentioned problems, the present inventors recognized that the development of a virtual reality-based cataract surgery simulator system is urgent, and completed the present invention.
