本缝合器设计原理与GF-1型管形消化道吻合器基本相同,而是利用两列交叉排列的钽丝缝钉作粘膜对粘膜全层外翻缝合。动物实验取7条12～15kg杂种狗,不作任何肠道准备,每条狗均用本缝合器作结肠外翻缝合一处,并同时用GF-1型管形消化道吻合器作结肠内翻吻合一处以资对照。术后分别于24、72小时及8、15、35、65、94天剖腹,所有缝(吻)合口均无渗血、裂开、感染或渗漏等并发症。标本均作病理切片检查,在15天以前的各次标本中内翻吻合愈合的程度略优于外翻缝合。但两者愈合过程
The stitching design principle and GF-1 type tubular digestive tract stapler basically the same, but the use of two rows of tantalum wire staples arranged alternately for mucosal eversion stitching. Animal experiments Take 7 12 ~ 15kg mongrel dogs, without any intestinal preparation, each dog with the stitching device for colostomy suture, and at the same time with GF-1 tube digestive tract stapling for the endoscopy In line with a control. Cesarean section was performed at 24, 72 hours and 8, 15, 35, 65 and 94 days after operation respectively. No complications such as bleeding, splitting, infection or leakage were found in all the joints. The specimens were examined by biopsy. The degree of anastomotic anastomosis in each specimen before 15 days was slightly better than that of the valgus suture. But both heal the process
