Circular stapler for gastrointestinal surgery
Anastomotic leak are one of the most serious complications in gastrointestinal surgery. Koppler represents a novel technology for reducing the risk of leak after stapling.
Anastomotic leaks occurs when the two ends of intestines are detached after being connected with staples after the surgical procedure. Gastrointestinal content may then leak out into the chest or abdominal cavity with a potentially fatal outcome for the patient.
Existing equipment for stapling with a fixed anvil have obvious limitations increasing the risk of anastomotic leakage. Koppler represent a novel design of a surgical stapler with a foldable anvil causing less stress on the anastomosis and thereby reducing the risk of leak after stapling.
The Inventors behind Koppler are Gastro-surgeons Brynjulf Ystgaard and Lars Cato Rekstad at St. Olavs Hospital in Trondheim. A patent application was filed in June 2016 and Koppler is now in a phase of extensive testing in dialogue with potential commercial partners. The product is developed and commercialised through NTNU Technology Transfer.
