Surgical Innovation

University of Otago scientists have patented a gel derived from squid that can reduce bleeding and scarring during surgery. The gel, named Chitodex, is a chemically modified form of the polymer chitosan, which is found in squid and crabs. Trials so far have involved spraying the gel into patients’ noses during endoscopic sinus operations, a procedure that has successfully prevented bleeding during surgery and any scarring afterwards. “This is a very exciting discovery for us. This combination makes it the ‘holy grail’ of medical gels,” said study leader Professor Brian Robinson in the NZ Herald. “It’s really a very exciting product which may have a profound effect on a lot of people around the world, not only for the sinuses but other surgery.”
