A circular stapler, also known as a circular stapling device or circular stapling instrument, is a medical tool used in surgical procedures, particularly in gastrointestinal surgery. It is commonly employed in procedures such as colorectal surgery and gastric surgery.
The primary purpose of a circular stapler is to create secure and consistent anastomoses (connections between two structures) in the digestive tract. This is often necessary when removing a portion of the intestine or stomach and reconnecting the remaining segments. Circular staplers are designed to form circular staples and simultaneously cut and suture the tissue, facilitating a more efficient and precise surgical procedure.
