背景:与传统的显微外科手术相比,超显微外科手术需要更精细的技能,在临床实施之前需要全面的培训。尽管存在各种训练模型,它们往往在成本方面达不到,伦理考虑,和感染风险。我们的目标是开发和评估具有成本效益的超显微手术的新型培训模式,伦理,和无风险。
方法:我们使用聚乙烯醇(PVA)液体胶制造管,聚醋酸乙烯酯树脂(PAR)木胶,和水胶体敷料(HCD),旨在确定合适的,超微手术训练模式的低成本候选人。在显微镜下使用10-0或11-0尼龙缝合线吻合这些管。我们评估了管制造所需的时间和成本,它们的直径,以及模型的整体可行性。
结果:PVA组制造15毫米长的腔管的平均时间和成本为33.5分钟和0.02美元,23分钟,PAR组0.02美元,HCD组63秒和0.40美元,分别。在PVA中,管的平均直径为0.49、0.58和1.55mm,PAR,和HCD组,分别。PVA和PAR管,它们透明而薄的墙壁,与HCD管相比,更容易评估吻合口的通畅性。
结论:我们成功地使用非活体材料开发新的超微手术训练模式,其特点是成本低,没有道德问题,消除感染风险。PAR和PVA管,特别是,适合接受超显微外科住院医师培训。
BACKGROUND: Supermicrosurgery demands more refined skills compared to traditional microsurgery, necessitating comprehensive training prior to clinical implementation. Despite the existence of various training models, they often fall short in terms of cost, ethical considerations, and infection risk. Our objective was to develop and evaluate novel training models for supermicrosurgery that are cost-effective, ethical, and risk-free.
METHODS: We fabricated tubes using polyvinyl alcohol (PVA) liquid glue, polyvinyl acetate resin (PAR) wood glue, and hydrocolloid dressing (HCD), aiming to identify suitable, low-cost candidates for a supermicrosurgery training model. These tubes were anastomosed under a microscope using 10-0 or 11-0 nylon sutures. We assessed the time and cost involved in tube fabrication, their diameters, and the overall feasibility of the models.
RESULTS: The average time and cost to fabricate a 15-mm-long luminal tube were 33.5 min and 0.02 USD for the PVA group, 23 min and 0.02 USD for the PAR group, and 63 s and 0.40 USD for the HCD group, respectively. The average diameter of the tubes was 0.49, 0.58, and 1.55 mm in the PVA, PAR, and HCD groups, respectively. The PVA and PAR tubes, with their transparent and thin walls, facilitated easier evaluation of anastomosis patency compared to the HCD tubes.
CONCLUSIONS: We successfully used non-living materials to develop new supermicrosurgery training models, characterized by their low cost, absence of ethical concerns, and elimination of infection risk. The PAR and PVA tubes, in particular, are suitable for resident training in supermicrosurgery.
