[Development and Application of Triple Cannula Dual-Lumen Vacuum Extractor]

Design and make triple cannula dual-lumen vacuum extractor to improve effect of decompression in operation of intestinal obstruction.Triple cannula dual-lumen vacuum extractor was applied in 32 patients who underwent operation of intestinal obstruction from 2012 to 2015 in our hospital. The effect of intestinal decompression and patient prognosis were observed.32 patients that used triple cannula dual-lumen vacuum extractor had good recovery except for one patient abdominal incision with fatty liquefaction. The other patients had one-stage healed without any complication such as intestinal fistula, abdominal infection etc.Application of triple cannula dual-lumen vacuum extractor in operation for intestinal decompression could avoid contamination of abdomen and injury of intestinal mucosa, which had satisfied effect of intestinal decompression and promoted the effect of operation for intestinal obstruction.
