Abstract

Background: Few studies have analyzed the effect of the size of the working space in training on the acquisition of endoscopic skills. In this study, adult- and infant-sized dry boxes (DBs) were used to verify how the size of the working space in training affects forceps manipulation and learning curve.

Material and methods: Seventy-two medical students were enrolled. The task was peg transfer. The training environment was divided into adult- and infant-sized DBs. Skill evaluations were also divided into adult- and infant-sized DBs (four groups in total). The forceps manipulation characteristics and task completion time were compared before and after training.

Results: Regarding skill evaluations using adult-sized DBs, there were no significant differences between the infant- and adult-sized DB-trained groups. Regarding skill evaluations using infant-sized DBs, there were no significant differences between the groups before training. After training, there was no significant difference in the total path length or average acceleration of the forceps between the groups. However, the infant-sized DB-trained group had a significantly faster average forceps velocity and faster task completion time than the adult-sized DB-trained group.

Conclusion: Training with a small DB is more efficient in acquiring smoother and faster forceps manipulation in a small working space.

根据干燥箱的大小评估技能习得特征。

背景：很少有研究分析了训练中工作空间的大小对掌握内窥镜技能的影响。本研究使用成人和婴儿大小的干燥箱（DBs）来验证训练中工作空间的大小如何影响镊子的操作和学习曲线：材料和方法：72 名医科学生参加了研究。材料和方法：72 名医科学生参加了训练，任务是栓子转移。训练环境分为成人和婴儿大小的 DB。技能评估也分为成人和婴儿大小的 DB（共四组）。对训练前后的镊子操作特征和任务完成时间进行了比较：在使用成人大小的 DB 进行技能评估方面，婴儿和成人大小的 DB 培训组之间没有显著差异。在使用婴儿大小的 DB 进行技能评估方面，训练前各组之间没有显著差异。训练后，各组在镊子的总路径长度或平均加速度方面没有明显差异。然而，婴儿大小的 DB 训练组的平均镊子速度和任务完成时间明显快于成人大小的 DB 训练组：结论：在狭小的工作空间内，使用小型 DB 进行训练能更有效地获得更流畅、更快速的镊子操作。

期刊介绍： Minimally Invasive Therapy and Allied Technologies (MITAT) is an international forum for endoscopic surgeons, interventional radiologists and industrial instrument manufacturers. It is the official journal of the Society for Medical Innovation and Technology (SMIT) whose membership includes representatives from a broad spectrum of medical specialities, instrument manufacturing and research. The journal brings the latest developments and innovations in minimally invasive therapy to its readers. What makes Minimally Invasive Therapy and Allied Technologies unique is that we publish one or two special issues each year, which are devoted to a specific theme. Key topics covered by the journal include: interventional radiology, endoscopic surgery, imaging technology, manipulators and robotics for surgery and education and training for MIS.
