技术领域technical field
本发明涉及医疗器械技术领域，具体涉及一种用于腹腔镜手术的切口封闭装置。The invention relates to the technical field of medical instruments, in particular to an incision sealing device for laparoscopic surgery.
背景技术Background technique
在临床外科中，进行腹腔镜手术时，需要向腹腔内冲入二氧化碳，形成气腹，以建立手术操作空间，而目前能进入气腹完成腔镜下胃肠吻合的器械主要是腔镜下直线型切割吻合器，这种直线型切割吻合器只能完成侧侧吻合，不能完成端侧吻合，导致开腹手术最常使用的管状吻合器不能在气腹条件下使用，全腹腔镜下行胃十二指肠端侧吻合、胃食道端侧吻合、食道空肠端侧吻合这些胃癌手术中的关键环节无法完成，而直线型切割吻合器所施行的侧侧吻合不能完全替代腹腔镜下胃肠端侧吻合技术。In clinical surgery, when performing laparoscopic surgery, it is necessary to inject carbon dioxide into the abdominal cavity to form a pneumoperitoneum to establish a surgical operation space. At present, the instruments that can enter the pneumoperitoneum to complete laparoscopic gastrointestinal anastomosis are mainly laparoscopic straight line Type cutting stapler, this linear cutting stapler can only complete side-to-side anastomosis, can not complete end-to-side anastomosis, resulting in the tubular stapler most commonly used in laparotomy can not be used under pneumoperitoneum conditions, laparoscopic gastric ten End-to-side duodenal anastomosis, gastroesophageal end-to-side anastomosis, and esophagus-jejunum end-to-side anastomosis cannot be completed, and the side-to-side anastomosis performed by the linear cutting stapler cannot completely replace the laparoscopic end-to-side gastrointestinal anastomosis Anastomosis technique.
