Appendectomy is the standard treatment for appendicitis, with the laparoscopic technique offering benefits like lower infection rates and quicker recovery. However, residents often have their first practical experience with the procedure on real patients, increasing surgical risks. In this context, medical simulation emerges as a crucial methodology, allowing professionals to experience a variety of scenarios while preventing harm to patients. The objective of this study is to describe the production of an "ex-vivo" simulation model for laparoscopic appendectomy.
Cold ceramic structures were used to manually shape the anatomical model of the appendix, ensuring its rigidity. On this model, we poured materials to create a flexible mold using acetic silicone. Once the mold was made, we filled it with thermo-moldable styrene polymer rubber, along with dye, and fused it at a specific temperature.
This process resulted in the manufacture of a piece that simulates the appendix, being tear-resistant and suturable, faithfully replicating the structure and characteristics of a human organ. The low weight of the materials facilitates transport, allowing them to be reproduced and used in various situations, from training in hospital settings to universities. The model is applicable in didactic simulations with medical students, residents, and surgeons. Its ease of production and low cost contribute to the practices being repeatable, ensuring a better development of surgical skills.
This work not only contributes to the advancement of medical simulation but also highlights the importance of innovative and collaborative solutions in improving medical education and promoting patient safety.
阑尾切除术是治疗阑尾炎的标准方法,腹腔镜技术具有感染率低、恢复快等优点。然而,住院医师通常在真实患者身上首次获得实际操作经验,从而增加了手术风险。在这种情况下,医学模拟成为一种至关重要的方法,可以让专业人员在避免对患者造成伤害的情况下体验各种场景。本研究的目的是描述一种腹腔镜阑尾切除术的“离体”模拟模型的制作方法。
使用冷陶瓷结构手动塑造阑尾解剖模型,以确保其刚性。在这个模型上,我们使用乙酸硅树脂来制造柔性模具。模具制作完成后,我们在其中填充热塑可成型的苯乙烯聚合物橡胶,同时加入染料,并在特定温度下融合。
这个过程制造出了一块模拟阑尾的部件,具有抗撕裂性和可缝合性,忠实地复制了人体器官的结构和特征。材料的低重量便于运输,使其可以在各种情况下进行复制和使用,无论是在医院环境中的培训,还是在大学中。该模型适用于医学生、住院医师和外科医生的教学模拟。其易于制作和低成本有助于实践的可重复性,确保了手术技能的更好发展。
这项工作不仅有助于医学模拟的发展,还强调了创新和协作解决方案在改善医学教育和促进患者安全方面的重要性。
