Medical simulators are a modern-day technology that allow clinicians to acquire the skills and knowledge needed to perform complex surgical procedures. Validating these simulators is crucial prior to their integration in surgical training programs. However, surgical simulators are typically validated as a whole, without emphasizing validation of the instruments themselves. The purpose of this study was to design and validate analog surgical instruments for a novel, minimally invasive spinal fusion simulator. The surgical procedure was performed on cadavers and on a surgical simulator by experienced spine surgeons to compare and validate the analog instruments. Observations were made to assess the duration of each task and the participants' interaction with each instrument, judged by finger position and location. Immediately after the completion of the simulator trial, participants completed a questionnaire on a 5-point Likert scale. The duration of each task in the surgical procedure varied between participants and training platforms (cadaver versus simulator), while participants' interaction with the instruments was similar, regardless of the training platform. Questionnaire results yielded an average score of 3.7/5 for the instrument-related questions. Subsequently, face and content validity were established. The results suggest feasibility and value in independently validating the analog instruments used in simulator training.
医学模拟器是一种现代技术，使临床医生能够获得进行复杂手术所需的技能和知识。在将这些模拟器集成到手术培训计划之前，对其进行验证至关重要。然而，手术模拟器通常作为一个整体进行验证，而不强调对仪器本身的验证。本研究旨在设计和验证一种新型微创脊柱融合模拟器的模拟手术器械。经验丰富的脊柱外科医生在尸体和手术模拟器上进行了手术操作，以比较和验证模拟器械。观察的目的是评估每个任务的持续时间以及参与者对每个仪器的交互作用，通过手指位置和位置来判断。在完成模拟器试验后，参与者立即在 5 点李克特量表上完成了一份问卷。手术过程中每个任务的持续时间因参与者和培训平台（尸体与模拟器）而异，而参与者与仪器的交互作用相似，无论培训平台如何。问卷结果对与仪器相关的问题的平均得分为 3.7/5。随后，确立了表面效度和内容效度。结果表明，独立验证模拟器培训中使用的模拟仪器是可行和有价值的。
