本文介绍食管渗疗器有关结构,设计原理与工作机制、适应症及使用方法等研究成果。该项研究旨在探索一条治疗食管癌特别是晚期食管癌的新途径。食管渗疗器利用半透膜的特性,通过局部应用高浓度抗癌药物、组织脱水萎缩、持续缓慢地机械扩张达到治疗目的。既无手术创伤,也无放、化疗的副作用。应用前景广阔。 This article describes the research results of esophageal osmotic devices related to structure, design principles, working mechanisms, indications, and methods of use. The study aims to explore a new approach to the treatment of esophageal cancer, especially advanced esophageal cancer. The esophageal osmotic device utilizes the characteristics of a semipermeable membrane to achieve therapeutic goals through the local application of high-concentration anticancer drugs, tissue dehydration atrophy, and sustained slow mechanical expansion. There are neither surgical trauma nor side effects of radiotherapy and chemotherapy. Wide application prospects.
