The alternative model of silicone for experimental simulation of suture of living tissue in the teaching of surgical technique

Abstract Purpose: To develop a silicone alternative model of tissue suture simulation to be used in the teaching of surgical technique. Methods: Twelve alternative models of silicone for tissue suture simulation were manufactured and implemented as a tool for suture pattern training of undergraduate medical students of Universidade Federal do Amazonas. Forty-eight students participated in the research. The evaluation of the proposed model was done through a questionnaire using the Likert scale, in order to verify the student satisfaction index of the alternative resource and its performance as opposed to the model historically used in the discipline, which is to suture in cloths. Results: The alternative model showed satisfactory results, especially with respect to the structural aspect, such as, better perception of anatomical planes, handling and transport. About 89.58% of positive concordant responses demonstrating expressive approval for incorporation of a complementary form of the alternative methodological proposal of the discipline of surgical technique. Conclusions: The model developed for experimental simulation of tissue sutures has proved to be a fully feasible alternative method for the training of this surgical skill. It is a simple, reproducible and low-cost model.

摘要
研究目的：开发一款组织缝合模拟硅胶替代模型，用于外科技术教学工作。
研究方法：制作12款组织缝合模拟硅胶替代模型，作为缝合模式训练工具，供亚马孙联邦大学（Universidade Federal do Amazonas）的医学本科生使用。本次研究共有48名学生参与。通过李克特量表（Likert scale）问卷对所提出的模型进行评估，以验证该替代教学资源的学生满意度，以及其相较于该课程既往使用的布料缝合模型的教学表现。
研究结果：该替代模型取得了令人满意的效果，尤其在结构层面表现突出，例如可更好地感知解剖平面、便于操作与传递。约89.58%的受访者给出正向一致性评价，表明学生对将该新型辅助教学方法纳入外科技术课程的认可度极高。
研究结论：本次开发的组织缝合实验模拟模型，已被证实是用于该外科技能训练的完全可行的替代方案。该模型操作简便、可重复性强且成本低廉。
