在医学教育中,医学生经常因翻译理论解剖学知识和基本外科技能(缝合,组织和仪器处理,和局部麻醉管理)付诸实践。这种困难的常见病因,其中,缺乏低成本和易于组装的低保真度缝合模型。这项研究的目的是证明一个经过验证的,实用,便宜,手形解剖训练模式。它是针对希望熟悉手部神经血管解剖学并提高其基本手术技能的医学生和毕业生。该模型只需要两个乳胶手套,棉花,每个学员两个不同的颜色标记来绘制大神经和血管的过程。施工需要不到15分钟。对于验证,80名学生作为志愿者参加了示范课程。他们在课程结束后评估了课程的有用性和自己的信心。根据李克特5分制,参与者的信心以统计学显著的方式增加(p<0.05)。所有参与者(100%)表示,他们的技能在仪器处理方面“显着提高”,解剖学研究,进行数字麻醉,和缝合技术。总体经验被评为“满意”或以上。所提出的模型可以实现安全温和的软组织处理,它类似于现实的人体组织。低成本,可用性,快速施工是最重要的特征,使这个经过验证的训练模型适合于获得基本的局部麻醉,尊重手神经血管解剖学,和缝合技巧。
During medical education, medical students are often frustrated by difficulties in translating theoretical anatomical knowledge and basic surgical skills (suturing, tissue and instrument handling, and local anesthetic administration) into practice. A common etiological factor for this difficulty, among others, is lack of a low-cost and easy-to-assemble low fidelity suturing model. The purpose of this study is the demonstration of a validated, practical, inexpensive, hand-shaped anatomy training model. It is addressed to medical students and graduates that wish to get acquainted with neurovascular anatomy of the hand and improve their basic surgical skills. The model requires only two latex gloves, cotton, and two different color markers per trainee to draw the course of large nerve and vessels. Construction requires less than 15 minutes. For validation, 80 students participated as volunteers in the demonstration course. They evaluated course usefulness and their own confidence after the course. According to the 5-point Likert scale, the participants\' confidence increased in a statistically significant way ( p < 0.05). All participants (100%) stated that their skills were \"significantly improved\" in terms of instrument handling, anatomy studying, performing digital anesthesia, and suturing technique. Overall experience was rated as \"satisfactory\" or above. The proposed model enables safe gentle soft-tissue handling, and it resembles a realistic human tissue. Low cost, availability, and fast construction are the most important characteristics, making this validated training model appropriate for acquiring fundamental local anesthesia, respect for hand neurovascular anatomy, and suturing skills.
