郁宝铭教授吻合器的间世已有半个多世纪,发明和应用最早的国家是原苏联,但未引起世人注意。Ravitch于50年代进一步发展了吻合器技术,并于1972年报道了胃肠道手术中应用吻合器的技术。而端端吻合器(EEA)的出现和应用于直肠低位吻合术中,迅速显示出它的优越性,简化了手术,因而很快被许多外科医师所采用,并取得了较好的效果。然而仍有不足之处。因为直肠低位吻合术的困难在于盆腔深部缝合操作,用吻合器替代手缝,但仍留下一个直肠残端的荷包缝合需用手操作。直肠残端的荷包缝合既是吻合器吻合中的关键部分。又是手法操作上很困难的一部分,因而在吻合器吻合与手法缝合的总疗效上差别不大,双吻合器(double stapling device)的问世是对EEA改
Professor Yu Baoming’s stapling device has been used for more than half a century. The earliest country to invent and apply it was the former Soviet Union, but it did not attract the attention of the world. Ravitch further developed the stapler technology in the 1950s and reported in 1972 on the use of stapler technology in gastrointestinal surgery. The emergence of end-to-end stapler (EEA) and its application in low rectal anastomosis have quickly demonstrated its superiority and simplified surgery, and it has quickly been adopted by many surgeons and achieved good results. However, there are still deficiencies. Because the difficulty of the low rectal anastomosis is due to the deep pelvic suture operation, using a stapler instead of a hand suture, a purse-string suture that leaves a rectal stump requires manual manipulation. The purse-string suture of the rectum stump is a critical part of the stapler anastomosis. It is also a difficult part of manipulative manipulation, and therefore there is little difference in the total efficacy of stapler anastomosis and manipulative stitching. The advent of double stapling devices is a change to EEA.
