Description

Intestinal canal fixer

Technical Field

The utility model relates to the field of medical instrument research, especially an intestinal fixer.

Background

The oral stapling anvil head delivery system (OrVil) anastomosis technology is a full-cavity esophageal jejunum anastomosis method used in laparoscopic full-gastrectomy, compared with the traditional assisted incision anastomosis technology, the OrVil anastomosis technology has more minimally invasive efficiency and more convenient operation, does not increase the incidence of intraoperative and postoperative complications, and is a safe and feasible laparoscopic reconstruction scheme.

When the OrVil anastomosis technology is used for esophagus jejunum docking, a fixing knot needs to be made in vitro by using a rubber ring with the width of about 0.3cm, the rubber ring is used for bundling the jejunum and a surgical instrument together, and the jejunum is prevented from slipping out or tearing embedded tissues in the docking process of the esophagus and the jejunum. However, the rubber ring can press the blood circulation of the intestinal tissue when the jejunum is fixed, and the intestinal tract tightly sleeved by the rubber ring is in an intestinal ischemia state before the anastomosis is finished and the rubber ring is cut open. Particularly, for inexperienced doctors, the operation time of the anastomosis process is too long in clinic, so that the intestinal ischemia time is too long. Poor blood transportation is a risk factor for esophageal jejunal anastomotic leakage, and once anastomotic leakage occurs, serious adverse effects can be caused on postoperative recovery. In addition, after the rubber ring is cut off in the abdominal cavity, a plurality of sections of fragments can be cut off, if the fragments are not completely taken out in the abdominal cavity, foreign bodies in the body can be caused, and adverse reactions can be caused.
