The Covidien Endo GIA Ultra 12mm XL is a type of surgical stapler used for laparoscopic (minimally invasive) procedures. Covidien, now part of Medtronic, manufactures this device, which is often employed in gastrointestinal, thoracic, and other surgical operations that require precise tissue cutting and stapling.

Here are some key points about this specific device:

• 12mm Diameter: Refers to the diameter of the trocar or instrument shaft that can be inserted through laparoscopic ports.
• XL (Extra Long): Indicates that this stapler has a longer shaft, allowing it to reach deeper anatomical sites.
• Endo GIA (Gastrointestinal Anastomosis): Refers to the device's primary function of creating anastomoses, or connections, between tissues, especially in gastrointestinal surgery. The device cuts tissue while simultaneously placing rows of staples on either side of the cut to ensure proper closure.

The Endo GIA Ultra stapler is typically used in procedures such as bowel resections, gastric bypass surgery, or lung surgery, where efficient tissue transection and secure closure are necessary.
