本实用新型涉及一种可吸收单向压缩性肠肠吻合器。The utility model relates to an absorbable one-way compressive intestinal anastomosis device.
背景技术Background technique
肠吻合术是腹部外科最常见的手术之一，也是外科医生必须掌握的手术技巧，是消化道重建的关键技术，关系到手术的成败。理想的肠吻合术应该能避免吻合口漏、狭窄、出血等并发症的发生，并且操作简便。改进和创新吻合技术一直是外科学研究的热点，到目前已发展出了数百种吻合方式。这些方式各有优缺点，但是没有一种能完全满足以上的要求，如临床上最常用的手工缝合法和吻合器法，都不能完全避免吻合口漏、狭窄、出血等并发症的发生。Intestinal anastomosis is one of the most common operations in abdominal surgery, and it is also a surgical technique that surgeons must master. It is a key technique for digestive tract reconstruction and is related to the success of the operation. An ideal intestinal anastomosis should be able to avoid complications such as anastomotic leakage, stenosis, and bleeding, and it should be easy to operate. Improving and innovating anastomosis technology has always been a hot spot in surgical research, and hundreds of anastomosis methods have been developed so far. These methods have their own advantages and disadvantages, but none of them can fully meet the above requirements. For example, the most commonly used manual suture and stapler methods in clinical practice cannot completely avoid the occurrence of complications such as anastomotic leakage, stenosis, and bleeding.
目前肠肠吻合目前主要采用传统手动缝合吻合和管型吻合器两种方式。At present, intestinal anastomosis mainly adopts two methods: traditional manual suture anastomosis and tubular stapler.
传统手动缝合吻合，即手术操作者使用传统外科方法，利用持针器、镊子和针线进行手动缝合、打结。Traditional manual suturing and anastomosis, that is, the operator uses traditional surgical methods to manually suture and tie knots with needle holders, tweezers, and needles and threads.
管型吻合器，即管型吻合器底钉座置入一端肠管内，另一端激发杆再置入，行端端吻合，但管型吻合器主要适用于直肠，部分乙状结肠，如需对结肠，小肠吻合需额外开一个小口，再对小口进行缝合。直线切割闭合器改良肠肠吻合，该方法无误做到肠端端吻合，会改变消化道原有结构。Tubular stapler, that is, the bottom nail seat of the tubular stapler is placed in one end of the intestinal canal, and the other end of the excitation rod is placed again, and the end-to-end anastomosis is performed. However, the tubular stapler is mainly suitable for the rectum and part of the sigmoid colon. If the colon is needed, An anastomosis of the small intestine requires an additional small opening, and then the small opening is sutured. The straight-line cutting and closing device improves intestinal anastomosis. This method can accurately achieve end-to-end anastomosis, which will change the original structure of the digestive tract.
综上所述,目前传统肠肠吻合方式存在操作难度大、术后吻合口漏发生率高的缺陷；而管型吻合器适用肠管范围较小；此外，上述传统的吻合方式在腹腔镜下操作更加困难，主要的吻合口漏的问题无法得到有效解决。In summary, the current traditional intestinal anastomosis method has the disadvantages of difficult operation and high incidence of postoperative anastomotic leakage; while the tubular stapler is suitable for a small range of intestinal canal; Even more difficult, the main problem of anastomotic leakage cannot be effectively resolved.
