8/16/2023 0 Comments Vr surgery gameThe advent of virtual reality (VR) based laparoscopic surgery simulators (VRLS) has changed the surgeons learning mode. Traditional laparoscopic surgical training usually conducts experiments on animals or corpses organs, leading to adverse effects, such as high cost, low reusability, and related ethical issues. However, residents generally have a long training period (6 years at least) to be qualified laparoscopic surgeons. This might provide a new way of assessing skill acquirement.Īs one of the modern minimally invasive procedures, laparoscopic surgery has become popular primarily due to its minor wounds and rapid recovery. Participants' performance is negatively correlated with cognitive load through quantitative physiological analysis. The results show that the VRLS could highly improve medical students' performance and enable the participants to obtain flow experience with a lower cognitive load. The performance and cognitive load computed from EEG are negatively correlated ( p < 0.05). The performance scores are enhanced significantly ( p < 0.01). ResultsĪfter training on VRLS, the time of the experimental group to complete the same task could drop sharply ( p < 0.01). Finally, the participants were required to fill the questionnaires about their cognitive load and flow experience. Senior surgeons graded their performance using newly designed hybrid standards for fundamental tasks and Global operative assessment of laparoscopic skills (GOALS) standards for colon resection tasks. The physiological data is used to compute cognitive load and flow experience quantitatively. Their operation and physiological data (heart rate and electroencephalogram) are recorded during the pre and post experiments. They were trained on VR-based laparoscopic surgery simulators (VRLS) in the middle of pre and post experiments. They conducted four pre and post experiments in the training box. Fifty-one participants were recruited from a pool of medical students. Our paper resorts to physiological approaches to objectively study the quantitative influence and performance analysis of VR laparoscopic surgical training system for medical students. Few of them investigate how to improve the surgery skills on specific dimensions substantially. However, most existing articles employ subjective methods to study the residents’ surgical skills improvement. Many research papers validate the effectiveness of VR-based surgical simulators in training medical students. Virtual reality (VR) surgery training has become a trend in clinical education.
