技术领域technical field
本实用新型涉及医疗器械技术领域，具体涉及一种减重代谢手术专用的充气性胃引导管。The utility model relates to the technical field of medical devices, in particular to an inflatable gastric guide tube specially used for weight loss and metabolism surgery.
背景技术Background technique
随着人们生活水平的提高，肥胖症患病率正以惊人的速度增长，目前已成为威胁人们身体健康和生命质量的一个重要问题。而近年来兴起的减重代谢手术则成为肥胖症患者获得长期、稳定减重疗效的唯一方法，同时也成为肥胖相关代谢性疾病最有效的治疗手段。减重代谢手术主要包括腹腔镜下袖状胃切除术及腹腔镜下胃转流术两大类，尽管它们手术方式不同，但它们有个共同的核心步骤是胃的裁切，而剩余胃囊体积的大小则在很大程度上决定了术后并发症的发生率及远期减重效果。为了使剩余胃囊体积能做到量化和均一化，目前临床常采用一种Bougie管作为胃体裁切时的引导管。然而，传统的胃引导管存在以下几个问题：1、腹腔镜下袖状胃切除术及胃转流术保留的胃囊的形状和体积各不相同，因此，临床需要采用两种不同的引导管做引导。2、目前采用的引导管管径很粗，质地较硬，临床常发生插管导致食管破裂、出血、血压下降等并发症【文献：杨建军, 朱晓强, 宋志成,等.减肥手术中Bougie管导致食道破裂的原因分析及对策[J].中华肥胖与代谢病电子杂志, 2015, 1(1):50-52.】。因此，临床迫切需要研制开发出一种新型的胃引导管，以克服上述缺陷。With the improvement of people's living standards, the prevalence of obesity is increasing at an alarming rate, and it has become an important problem that threatens people's health and quality of life. In recent years, bariatric and metabolic surgery has become the only method for obese patients to obtain long-term and stable weight loss efficacy, and it has also become the most effective treatment for obesity-related metabolic diseases. Bariatric and metabolic surgery mainly includes two categories: laparoscopic sleeve gastrectomy and laparoscopic gastric bypass. Although they have different surgical methods, they have a common core step that is the cutting of the stomach, and the remaining gastric pouch. The size of the volume largely determines the incidence of postoperative complications and long-term weight loss. In order to quantify and homogenize the volume of the remaining gastric pouch, a Bougie tube is often used as a guide tube for gastric body cutting. However, the traditional gastric guiding tube has the following problems: 1. The shape and volume of the gastric pouch retained in laparoscopic sleeve gastrectomy and gastric bypass surgery are different, so two different guiding methods are required in clinical practice. tube as a guide. 2. The diameter of the guide tube currently used is very thick and the texture is hard, and complications such as esophagus rupture, hemorrhage, and blood pressure are often caused by intubation in clinical practice. Cause analysis and countermeasures of rupture[J]. Chinese Journal of Obesity and Metabolic Diseases, 2015, 1(1):50-52.]. Therefore, there is an urgent need to develop a new type of gastric guide tube to overcome the above-mentioned defects.
实用新型内容Utility model content
