A Teat Curette (Cornell or Swedish model) is a highly specialized veterinary surgical instrument used primarily in dairy cattle to remove growths, scar tissue, calculi, or fibrous blockages from the teat cistern and canal. It helps restore normal milk flow when an animal suffers from physical obstructions inside the teat.

Obstruction Removal: Scrapes away unwanted tissue masses or "spiders" (fibrous growths) that block the passage of milk.
