技术领域technical field
本发明属于一种医用吻合装置，具体涉及一种消化道无缝线吻合装置。The invention belongs to a medical anastomosis device, in particular to a sutureless alimentary canal anastomosis device.
背景技术Background technique
医用吻合装置，用于人体消化管道之间的无缝线吻合，例如小肠手术后小肠两断端之间的吻合。The medical anastomosis device is used for the sutureless anastomosis between the digestive tracts of the human body, such as the anastomosis between the two ends of the small intestine after small bowel surgery.
人体空腔脏器或者血管的吻合及重建是外科手术中的重要操作，以往是应用缝线手工缝合完成，可以达到令人满意的效果，但是操作费时，吻合效果依赖术者缝合技术及经验，缝线相关的并发症也不可避免。数百年来外科医生仍然一直在探索不借助缝线的可降解或者不可降解的吻合装置或者方法来降低手术难度、简化手术步骤、减少术后并发症，并在近几十年来取得了很大的进展。1978年日本Obora等人率先应用两个磁环之间相互的磁性吸力完成了人体管道断端之间的吻合，并提出了磁吻合的概念，其原理在于压榨人体管道断端组织，导致磁环间组织逐渐坏死，断端间瘢痕愈合而完成吻合；之后不断有人将磁吻合应用于消化管道的吻合，本中心也研究设计出了一系列血管、胆肠、肠肠磁性吻合装置。但以往的磁性吻合装置普遍存在异物残留，磁体较大不易取出的弊端。1984年美国Handy等人的发明专利介绍了一种人体空腔脏器或者人体管道之间吻合用装置，生物可降解吻合环（biofragmentable anastomotic ring，BAR），其原理类似磁吻合，利用机械力使断端组织压榨坏死、瘢痕愈合；这种装置采用了可降解聚合材料，可以在完成消化道吻合的基础上使吻合装置在人体内完全降解并排出，无异物残留，并证明了其在肠吻合中的优越性，目前已经完成商品化，广泛应用于临床肠肠吻合。但这种可降解吻合装置仍较为复杂，因操作原因而出现的并发症不可避免。The anastomosis and reconstruction of human hollow organs or blood vessels are important operations in surgical operations. In the past, sutures were used to suture manually, which can achieve satisfactory results, but the operation is time-consuming, and the anastomosis effect depends on the suturing skills and experience of the surgeon. Suture-related complications are also inevitable. For hundreds of years, surgeons have been exploring degradable or non-degradable anastomotic devices or methods without sutures to reduce the difficulty of surgery, simplify surgical steps, and reduce postoperative complications, and have made great progress in recent decades. Progress. In 1978, Obora and others in Japan took the lead in using the mutual magnetic attraction between two magnetic rings to complete the anastomosis between the broken ends of human pipelines, and proposed the concept of magnetic anastomosis. The interstitial tissue is gradually necrotic, and the scar between the broken ends heals to complete the anastomosis; after that, some people continue to apply magnetic anastomosis to the anastomosis of the digestive tract. Our center has also researched and designed a series of magnetic anastomosis devices for blood vessels, biliary intestines, and intestines. However, the previous magnetic anastomosis devices generally have the disadvantages of foreign matter residues and large magnets that are difficult to remove. In 1984, the invention patent of Handy et al. in the United States introduced a device for anastomosis between human hollow organs or human pipelines, the biodegradable anastomotic ring (biofragmentable anastomotic ring, BAR). Stumped tissue necrosis and scar healing; this device uses a degradable polymer material, which can completely degrade and discharge the anastomotic device in the human body on the basis of completing the anastomosis of the digestive tract, without foreign matter residue, and has proved its use in intestinal anastomosis The superiority of the method has been commercialized and widely used in clinical intestinal anastomosis. However, this degradable anastomosis device is still relatively complicated, and complications due to operational reasons are inevitable.
