Research On The Design And Evaluation Of Brain Tumor Virtual Surgery Simulator

Brain tumor refers to a new organism that grows in the cranial cavity.It is the result of abnormal differentiation and proliferation of various tissues located in the brain.It is also called intracranial tumor and brain cancer.At present,most people lack understanding of brain tumors,and a large number of patients died without timely early diagnosis and treatment,so people should pay attention to it.In traditional medicine,surgeons can only use the anatomy of cadavers and previous surgical experience.According to surveys,nearly 30% of clinical operations do not involve the participation of resident physicians,and there are few opportunities for surgery;and with the expansion of the number of enrollments in medical schools,the lack of corpse resources has led to the insecurity of surgical training;plus The problems of long operation training period,low efficiency and high cost make it difficult to train a qualified surgeon,which seriously affects the efficiency of operation.In response to this problem,the paper focuses on the development of a surgical simulator for brain tumor resection,aiming to solve the problem of surgeons training for brain tumor surgery.This article focuses on a self-designed and developed virtual reality-based training system for neurosurgery brain tumor surgery,combined with the Cumulative Summation For Learning Curve(LC-CUSUM)method,and analyzes the preoperative basic training and brain tumors During the operation,the equipment is operated and data collected through cooperation with hospital residents and medical students,and the training method is made reliable through subjective and objective evaluation.The specific work of the thesis consists of the following aspects:(1)Using the Unity 3D platform to design and complete the basic training modules for brain tumor surgery,including: plate drilling,film shearing,and small object transfer.The system function is realized through virtual reality technology.(2)Build the system UI framework.Including the main interface,basic training module,3D reconstruction module,surgery scene,etc.Makes the operation simple and comfortable,and makes it easy for users to operate.The improvement of surgical skills was evaluated by recording experimental data during training.Invite residents and medical students to participate in the surgical evaluation process.The subjective evaluation questionnaire was recorded by experiencing the surgical process,and the experimental data was processed by the method of cumulative learning curve,drawing the training curve of the trainer and analyzing the evaluation result.Through the analysis of subjective evaluation and experimental data,it is found that the surgical skills of the personnel participating in the training have been significantly improved.
