Abstract

Background

Lumbar puncture is an essential medical procedure whose objective is to obtain cerebrospinal fluid. Lumbar puncture is considered a complex procedure, mainly for novice residents who suffer from stress and low confidence, which may result in harm to the patient.

Methods

The LPVirSim, has been developed in four stages: i) requirements analysis through user-centred design; ii) prototyping of the virtual environment and the haptic component; iii) preliminary tests with Ph.D. students and physicians using two haptic devices (Omega.7 and Sigma.7); iv) a user study where physicians evaluated the usability and user experience.

Results

The LPVirSim integrates non-technical skills and the possibility of representing different patients for training. Usability increased from 61.76 to 68.75 in the preliminary tests to 71.43 in the user study.

Conclusions

All the results showed good usability and demonstrated that the simulator arouses interest and realistically represents a Lumbar puncture, through the force and visual feedback.

用于医学生培训的腰椎穿刺虚拟模拟器的开发：初步评估。

背景：腰椎穿刺是一项重要的医疗手术，其目的是获取脑脊液。腰椎穿刺被认为是一项复杂的手术，主要针对那些承受压力和信心不足的新手住院医师，这可能会对患者造成伤害。方法：LPVirSim分四个阶段开发：i）通过以用户为中心的设计进行需求分析；ii）虚拟环境和触觉组件的原型设计；iii）使用两种触觉设备（Omega.7和Sigma.7）对博士生和医生进行初步测试；iv）医生评估可用性和用户体验的用户研究。结果：LPVirSim集成了非技术技能和代表不同患者接受培训的可能性。可用性从初步测试中的61.76增加到68.75，在用户研究中增加到71.43。结论：所有结果都显示出良好的可用性，并表明模拟器通过力和视觉反馈引起了人们的兴趣，并真实地再现了腰椎穿刺。

期刊介绍： The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
