在对我们机构的学生进行的一项调查中，缝合是最受期待的模拟操作工作坊；然而，皮肤垫的成本、质量和可获取性往往使缝合工作坊难以开展。医院内部制作可用于制造非商业性、高保真且低成本的模拟模型。我们介绍了我们的模拟皮肤模型的制作、价值以及表面效度验证。
利用医院内部的制作实验室，我们开发了一种皮肤和皮下组织模型。我们的模型使用多种市售材料来模拟表皮、真皮、皮下脂肪、筋膜和肌肉。通过与其他常用的商业皮肤模型进行比较，进行了成本分析。专家外科医生对我们的模型与其他商业模型相比的材料特性、耐用性和整体质量进行了评估。
我们新型皮肤垫模型的材料成本是五种不同的常用泡沫和硅胶基商业皮肤模型平均成本的30.9%。这种低成本模型比商业模型更耐用，不需要皮肤垫支架，并且比商业产品具有更高的保真度。除了皮肤缝合，我们的模型还可用于模拟筋膜缝合或筋膜切开术。
利用医院内部工作空间制作模型是一种在降低成本的同时提高手术模拟质量的有效策略。我们制作廉价且高保真皮肤垫的方法可用于多种软组织模型。
In a survey of students at our institution, suturing was the most desired workshop for simulation; however, cost, quality, and availability of skin pads is often prohibitive for suturing workshops. In-hospital fabrication may be utilized to manufacture non-commercial, high-fidelity, and low-cost simulation models. We describe the production, value, and face validation of our simulated skin model. Using an in-hospital fabrication laboratory, we have developed a model for skin and subcutaneous tissue. Our model uses a variety of commercially available materials to simulate the epidermis, dermis, subcutaneous fat, fascia, and muscle. A cost analysis was performed by comparing it to other commonly used commercial skin models. Expert surgeons assessed the material characteristics, durability, and overall quality of our model in comparison to other commercial models. The materials cost of our novel skin pad model was 30.9% of the mean cost of five different commonly used foam and silicone based commercial skin models. This low-cost model is more durable than the commercial models, does not require skin pad holders, and is of higher fidelity than the commercial products. In addition to skin closure, our model may be used to simulate fascial closure or fasciotomy. Model creation using in-hospital workspaces is an effective strategy to decrease cost while improving quality of surgical simulation. Our methods for creation of an inexpensive and high-fidelity skin pad may be purposed for several soft tissue models.
