Biomechanical Properties of the Large Intestine

The large intestine is an important part of the human digestive system and the target of many diseases. The biomechanical properties of the large intestine are closely related to the proper functioning of its mechanical behavior. Therefore, the study of its biomechanical properties can help to better understand the key factors of lesions and provide a theoretical basis for the research and application of disease treatment, artificial anal sphincter, and other related medical devices. Physiologic structure of the large intestine is the basis for the study of its biomechanical properties. Constitutive models are commonly used to describe the biomechanical properties of soft tissues and to provide a mathematical characterization of the effects of biological components on the behavior of materials. The studies and results of biomechanical experiments provide a basis for determining the material parameters and the causes of functional damage to the material. In this paper, the biomechanical properties of the large intestine are investigated from two aspects: active properties and passive properties, and three perspectives: physiological structure, constitutive models, and biomechanical experiments. The paper concludes that their effective combination is an important comprehensive method to study the biomechanical properties of the large intestine. It provides a new perspective for the study of biomechanical properties of the large intestine, and provides a theoretical basis for future related biomechanical studies and the development of related medical devices.
