Ex vivo model with bovine heart: a proposal for training microscopic dissection and vascularmicroanastomoses.

ABSTRACT Training is a process that requires patience and constant practice. The execution of microscopic procedures is present in the day-to-day of several surgical specialties, but unfortunately experimental models are not easy to access in our environment. We propose a bovine heart model used by residents and young surgeons in the training of microscopic dissection and microanastomoses. It is described the assembly of this model, which can be performed individually and with accessible material to the surgical departments. Our experience in the preparation of the pieces, as well as tips for the process, are described in the text. The bovine myocardial model can be reproduced in any center with benches and surgical instruments. Low cost, fast preparation, and wide availability of the used tissue are among the advantages of this model. We consider the project useful in the training of surgical residents and young surgeons.

摘要：外科训练是一项需要耐心与反复练习的过程。外科诸多专科的日常工作中均涉及显微操作，但受限于当前临床环境，实验模型往往难以获取。为此，我们提出一种可供外科住院医师与青年外科医师开展显微解剖及显微吻合训练的牛心模型。本文详述了该模型的组装流程，其既可独立完成搭建，所需耗材亦均为外科科室易于获取的常规物资。文中还分享了我们在标本制备过程中的实操经验与技巧。该牛心肌模型可在任何配备手术台与外科器械的医疗中心进行复刻，其优势涵盖成本低廉、制备快捷以及供体组织来源广泛。我们认为该模型在外科住院医师及青年外科医师的培训工作中具备实用价值。
