Small Bioprinter for Vocal Cord Surgery
A flexible bioprinter, small enough to print wound-healing material, has been developed for use during vocal cord surgery.
Healing hydrogels, which are cross-linked polymer chains that hold a lot of water, can promote tissue healing and prevent postsurgical complications.
Healing hydrogels can promote tissue healing and prevent postsurgical complications.
However, the current method of delivery using a needle from the outside lacks precision, often failing to reach important areas in the vocal cords.
Breakthrough by Researchers
Researchers led by Luc Mongeau, a professor of mechanical engineering at McGill University, have created a new way to deliver hydrogels during surgery by printing the material directly into the throat.
- The bioprinter is small enough to be used during vocal cord surgery.
- The device prints wound-healing material directly into the throat.
