动机：外科干预措施的精确和正式规范是许多外科应用程序的必要要求，包括教和学、质量评估和评估以及计算机辅助外科手术。目前，手术过程是通过以下不同的方法来模拟的。这种多样性缺乏一个普遍认可的概念基础，从而阻碍了过程数据的可比性、互操作性和统一解释。目标：然而，如果科学模型在相同的背景下共享一致的概念和形式的数学基础，将是有益的。这种统一的基础将简化数据的获取和交换、研究结果的过渡和解释以及方法和工具的转移和调整。因此，我们提出了一个通用的、形式化的描述手术过程的框架，并给出了它的设计方法。方法：该方法遵循四个层次的翻译方法，包括以语言学理论为导向的形式层次的本体论基础。结果：建立了一个建立在本体论基础上的、形式上和数学上精确的手术过程建模的统一框架。通过将该框架应用于四种当代外科手术过程建模方法，验证了该框架的表达能力和统一能力。结论：该四层方法能够形式化地获取手术干预知识。自然语言术语被一致地翻译到实现级别，以支持用户用自然语言表达其关于过程的专家知识的研究领域，但与此相反，统计分析或数据挖掘需要基于数学上形式化的数据集来执行。这种翻译方法的可获得性是关于未来手术室研究的有价值的扩展。(C)2010年爱思唯尔BM。版权所有。
Motivation: The precise and formal specification of surgical interventions is a necessary requirement for many applications in surgery, including teaching and learning, quality assessment and evaluation, and computer-assisted surgery. Currently, surgical processes are modeled by following various approaches. This diversity lacks a commonly agreed-upon conceptual foundation and thus impedes the comparability, the interoperability, and the uniform interpretation of process data.Objective: However, it would be beneficial if scientific models, in the same context, shared a coherent conceptual and formal mathematical basis. Such a uniform foundation would simplify the acquisition and exchange of data, the transition and interpretation of study results, and the transfer and adaptation of methods and tools. Therefore, we propose a generic, formal framework for specifying surgical processes, which is presented together with its design methodology.Methods: The methodology follows a four-level translational approach and comprises an ontological foundation for the formal level that orients itself by linguistic theories.Results: A unifying framework for modeling surgical processes that is ontologically founded and formally and mathematically precise was developed. The expressive power and the unifying capacity of the presented framework are demonstrated by applying it to four contemporary approaches for surgical process modeling by using the common underlying formalization.Conclusions: The presented four-level approach allows for capturing the knowledge of the surgical intervention formally. Natural language terms are consistently translated to an implementation level to support research fields where users express their expert knowledge about processes in natural language, but, in contrast to this, statistical analysis or data mining need to be performed based on mathematically formalized data sets. The availability of such a translational approach is a valuable extension for research regarding the operating room of the future. (C) 2010 Elsevier BM. All rights reserved.
