适于内镜下胃肠重建的磁吻合环的优化设计

摘要

Anastomosis and reconstruction of gastrointestinal tract is the basic technique of general surgery. The existing hand-sewn and anastomat anastomosis must be done in the situation of open or laparoscopic surgery. However, no matter open or laparoscopic surgery, both of them will bring unexpected trauma to the patient. Especially for those who suffer from advanced gastrointestinal malignant tumor, it is a dilemma for surgeons whether to give them a palliative operation. Meanwhile it is contrary to the now advocated theory of minimally invasive surgery and fast tract surgery. Therefore, how to reduce the trauma from anastomosis and reconstruction of gastrointestinal tract is of great clinical signiifcance. Based on the years of study of magnetic compression technique and magnamosis, this study introduces an optimal designed magnamosis ring for anastomosis and reconstruction of gastrointestinal tract which can be used via gastroscope. Especially for patients suffering advanced gastrointestinal malignant tumor, this device made traditional anastomosis and reconstruction surgery of gastrointestinal tract transforming to endoscopic procedures, which realizes the palliative operation meanwhile reduces trauma from traditional surgery. This article will introduce structure characteristics of the magnamosis ring in details, operation path and advantages of clinical application.%胃肠道吻合重建是普通外科最基本的操作，现有的胃肠道缝线吻合或吻合器吻合必须通过开腹手术或腔镜手术来完成。然而，无论是开腹手术还是腔镜手术都会给患者带来巨大创伤，尤其是对于胃肠道恶性肿瘤晚期患者，通过手术来达到姑息治疗的目的往往令外科医生难以均衡利弊，同时这也与目前所倡导的微创外科和快速康复外科理念不相符。因此，降低患者胃肠吻合重建创伤有着重要临床研究意义。笔者在磁压迫吻合技术多年研究基础上，优化设计了一种用于胃肠吻合重建的磁性吻合环，借助该吻合环可实现胃镜下操作，尤其适用于胃肠道肿瘤所造成的恶性梗阻姑息治疗，该方法可将传统外科手术变成内镜操作，不仅能实现姑息治疗目的，而且大大降低了传统手术吻合重建带给患者的打击。本文详细介绍该磁吻合环的结构设计特点、手术操作路径及临床应用优势。
