技术领域technical field
本发明涉及医疗器械技术领域，尤其涉及一种肠道吻合口保护装置。The invention relates to the technical field of medical devices, in particular to an intestinal anastomosis protection device.
背景技术Background technique
在肠道进行切割缝合手术后（例如低位直肠癌吻合手术），为了避免排泄物污染吻合口，造成吻合口感染，一般都需要对吻合口进行保护。After intestinal cutting and suturing (such as anastomotic surgery for low rectal cancer), in order to prevent excrement from contaminating the anastomotic stoma and causing anastomotic stoma infection, it is generally necessary to protect the anastomotic stoma.
现有保护吻合口比较普遍的做法是：在人体腹壁上做保护性肠造口，即是将结肠截断后，将与食管、胃相通的结肠断端拉至腹壁并固定在腹壁上，形成临时肠造口，待直肠处吻合口愈合好后，再实施二次手术进行肠道还纳。然而，这样的做法需进行二次还纳手术，会对病人造成二次伤害。The common way to protect the anastomotic stoma is to make a protective enterostomy on the abdominal wall of the human body, that is, after the colon is cut off, the broken end of the colon connected with the esophagus and stomach is pulled to the abdominal wall and fixed on the abdominal wall to form a temporary Enterostomy, after the rectal anastomosis is healed, a second operation is performed to restore the intestine. However, such an approach requires a second recovery operation, which will cause secondary damage to the patient.
